Hermes Agent

Hermes Agent v0.20.0 (2026.8.3)

August 3, 2026

• •Talk to Hermes — streaming, conversational voice with barge-in — Voice mode used to mean: speak, wait for the whole reply to generate, then listen to one long audio file. Now Hermes speaks clause-by-clause as the response streams, you can interrupt it mid-sentence by just talking (it stops, listens, and the model is told you cut in), and busy-aware silence detection means it doesn't talk over you. This works in CLI voice mode, on the desktop, and through gateway adapters. Talking to Hermes finally feels like a conversation, not a voicemail exchange. (#69511, #73862, #74223, #74000, #69602 — @teknium1, @OutThisLife)
• •Wake words and hands-free control — Say your own open-vocabulary wake phrase ("hey Hermes", or anything you pick) and Hermes starts listening — detection runs on-device, so no audio leaves your machine while it waits. Multi-profile voice routing means different wake words can reach different profiles, and saying "stop" ends the voice chat on every surface without touching the keyboard. Your terminal is now something you can talk to from across the room. (#70509, #73106, #73933 — @teknium1)
• •Voice on every platform — Send a voice note to Hermes on WhatsApp, Feishu, DingTalk, LINE, QQ, Photon, or Weixin and it's transcribed and answered; auto-TTS replies are delivered platform-aware (opus where platforms want opus, captions attached correctly). STT is now fully configurable — its own hermes tools category, GUI toggles, dashboard dropdowns, unified language resolution so transcripts stop coming back in the wrong language, and OpenAI's gpt-transcribe support. One unified spoken-text preprocessor cleans markdown, code, and URLs out of speech across all TTS providers. (#73515, #73508, #73910, #73513, #73067 — @teknium1)
• •Research you can trust — grounded citations with fact-checking — The new grounded-citations skill makes Hermes produce research where every claim is backed by a verifiable source: quotes are matched against the actual page text (not hallucinated), citations link to the exact evidence, and a fact-checking mode turns the same machinery on any document or claim you hand it — it tells you what checks out, what doesn't, and what couldn't be verified. If you use Hermes for research, this is the difference between "sounds right" and "provably sourced." (#71698, #77104 — @teknium1)
• •Outbound webhooks — Hermes pushes events to your systems — Until now, integrating with Hermes meant polling or listening on a platform. Now Hermes pushes signed lifecycle events (session activity, turn completions, tool events) to any HTTP endpoint you register — with HMAC signatures so your receiver can verify authenticity. Wire Hermes into your CI, your home automation, your dashboards, or any service that speaks HTTP, with no polling loop. (#69406 — @teknium1)
• •The desktop app becomes a platform — artifacts, plugin SDK, quick entry — Hermes desktop now renders artifacts: versioned cards with sandboxed live preview in a right-rail viewer, so generated HTML/apps run safely next to the chat. A real plugin SDK landed with Kanban as its founding plugin, ctx.download for handing users files, floating pane placement, and multiple GUI windows. A global-hotkey quick-entry window captures a thought into any session from anywhere in your OS. The desktop stopped being a chat client and started being a workbench. (#72345, #61173, #74413, #72315, #68259, #73143 — @OutThisLife, @teknium1)
• •Hermes speaks Agent-to-Agent — A2A v1.0 — A new bundled plugin implements the Agent-to-Agent protocol, so Hermes can discover, talk to, and be driven by other A2A-compatible agents. This closes issue #514 — one of the oldest open feature requests in the repo. If you're building multi-agent systems with heterogeneous stacks, Hermes now has a standard wire protocol for joining them. (#77109 — @teknium1)
• •CLI power-user wave — !command runs a shell command instantly without spending a model turn. /init scans your project and generates (or updates) an AGENTS.md. /diff shows staged/all/session changes from any surface, /context breaks down exactly what's filling your context window, /focus gives you a reduced-output view with hidden-line recovery, and Ctrl+S stashes a half-written prompt into a browsable panel. Plus hermes import-agent migrates your Claude Code or Codex CLI setup into Hermes in one command.

Hermes Agent v0.19.0 (2026.7.20) — The Quicksilver Release

July 20, 2026

• •Hermes got dramatically faster — first token in a fraction of the time — Cold-start "Initializing agent..." used to eat ~4.3 seconds before your first turn even reached the model; it's now ~0.9s, an ~80% cut that applies to the CLI, gateway, TUI, desktop, and cron alike. Round 2 attacked what you see while waiting: reasoning models now stream their thinking live by default (no more staring at a spinner for 30 seconds), and the response box paints per token instead of per line. If Hermes ever felt like it took a deep breath before answering, that breath is gone. (#59332, #59389 — @teknium1)
• •The desktop app speed wave — 20+ targeted perf PRs — Long replies used to cost 14× more CPU in the markdown splitter than they do now; giant diffs froze the review pane until we virtualized it; switching sessions thrashes layout no more. Streaming no longer re-renders the sidebar and every tool row per token, profile backends pre-warm on hover intent, and boot-hidden panes mount at idle instead of on the cold-start critical path. The net effect: the desktop app feels like a native app under load, even with huge transcripts and busy agents. (#67154, #67818, #65898, #66033, #66747, #67742 and more — @OutThisLife)
• •Manage your Nous plan from the terminal — `/subscription` and `/topup` — Changing your subscription used to mean a trip to the billing website. Now /subscription opens a full flow right in the TUI or classic CLI: see your plan and remaining allowance, preview exactly what an upgrade costs ("Pay $46.30 & upgrade now") or when a downgrade takes effect, and apply it — with scheduled-change banners and undo. The desktop app got a matching billing settings tab. Your wallet never has to leave the keyboard. (#51639, #61054, #61067 — @alt-glitch)
• •Smart approvals are now the default — When Hermes wants to run a flagged command, an LLM reviewer now assesses it independently instead of asking you to approve every single one — and each verdict covers only that exact command, so a later command matching the same pattern gets its own review. Combined with the new user-defined deny rules (which block commands even under yolo mode) and /deny <reason> (which tells the agent why you refused so it course-corrects), day-to-day approval fatigue drops sharply without giving up control. (#62661, #59164, #54518 — @teknium1)
• •Plug your password manager into Hermes — Bitwarden & 1Password secret sources — API keys no longer have to live in a plaintext .env. A new pluggable SecretSource interface lets Hermes fetch secrets from Bitwarden and 1Password (op:// references) at load time, with multiple vaults enabled simultaneously, deterministic precedence, conflict warnings, and per-variable provenance. This consolidated eleven competing community PRs into one orchestrated interface — future vault providers drop in as plugins. (#59498 — @teknium1, 1Password provider salvaged from @hwrdprkns)
• •Watch your subagents work — live transcripts + durable background delegation — delegate_task dispatches now return live transcript files you can tail -f the moment the subagents launch: every tool call, result, and streamed reply, one human-readable log per child. And background delegation completions are now durable — if the process restarts mid-run, results are restored and delivered through an ownership-checked ledger instead of vanishing. Fan out a fleet, watch any worker live, and never lose the results. (#67479, #63494 — @teknium1)
• •A finished answer can no longer be lost — the delivery-obligation ledger — If the gateway died between generating your response and confirming the platform actually delivered it, that answer used to be silently gone (and you'd paid for the turn). Final responses are now recorded in a durable ledger in state.db around the platform send and redelivered on the next boot — closing a P1 silent-loss window for Telegram, Discord, Slack, and every other channel. (#67181 — @teknium1)
• •One gateway, many profiles — profile-based message routing — A single multiplexed gateway sharing one bot token can now route specific guilds, channels, or threads to different profiles — each with fully isolated config, skills, memory, and secrets. Point your work Discord server at the work profile and your hobby server at personal, from one bot. A second multiplex hardening wave means one misconfigured profile can no longer take down the whole gateway. (#64835 salvaging @Burgunthy, #65700, #60589 — @teknium1, @benbarclay + six salvaged contributors)

Hermes Agent v0.18.2 (2026.7.7.2)

July 8, 2026

• •fix(whatsapp): unpin Baileys from git commit, use published 7.0.0-rc13 (#60643) — the WhatsApp bridge dependency now installs from the published npm release instead of a pinned git commit, making installs and Docker image builds reliable.

Hermes Agent v0.18.1 (2026.7.7)

Hermes Agent v0.18.0 (2026.7.1) — The Judgment Release

July 1, 2026

• •Mixture-of-Agents is now a first-class model you can pick — MoA used to be a mode you toggled; now every named MoA preset shows up as a selectable model under a moa provider, right alongside Claude, GPT, and Grok in every model picker (CLI, TUI, desktop, gateway). Pick "my-council" the same way you'd pick any model, and Hermes routes your prompt through that ensemble automatically. An ensemble of frontier models deliberating on your hardest questions is now one selection away, on every surface. (#46081, #53548, #53561 — @teknium1)
• •See every model's reasoning, then watch the answer stream in — When a MoA ensemble runs, each reference model's full output now renders as its own labelled block — you can read what GPT-5 thought, what Claude thought, and what Grok thought, before the aggregator synthesizes them into one answer. And that final answer now streams to you live instead of appearing all at once after a long silence. This works in the CLI, the TUI, and the desktop app. You get to watch the committee deliberate, not just read the verdict. (#53793, #53855, #55625, #56101 — @teknium1)
• •The agent verifies its own work — "done" means proven, not claimed — Hermes now records verification evidence for coding work and can decide it's finished by actually running your project's checks, not by asserting success. /goal gained completion contracts: you state what "done" looks like, and the standing-goal loop judges completion against that evidence instead of stopping when the model feels like it. There's a pre_verify hook for wiring in custom checks and a one-time migration that tunes the defaults sensibly. The difference between "I think I fixed it" and "the tests pass, here's proof." (#50501, #52285, #55413, #53552 — @teknium1, @OutThisLife)
• •`/learn` — turn anything into a reusable skill by describing it — Run /learn <anything> and Hermes distills a reusable skill out of whatever you point it at — a directory, a URL, or just the workflow you walked it through five minutes ago. It writes the skill to the standards in your CONTRIBUTING.md automatically. The next time you need that workflow, it's already there. Teaching Hermes a new trick is now a single command, not a manual skill-authoring session. (#51506, #52372 — @teknium1)
• •`/journey` — a playable timeline of everything Hermes has learned about you — The CLI and TUI gained /journey, a learning timeline that shows the memories and skills Hermes has accumulated over time — and you can edit or delete any of them right from the view. Pair it with the desktop's new memory graph (a top-down, playable radial timeline of memories and skills) and for the first time you can actually see what your agent knows, watch it grow, and prune what's wrong. Your agent's memory stops being a black box. (#55555, #55859, #55226 — @OutThisLife)
• •Delegate a pile of work and keep going — background fan-out — delegate_task can now fan out multiple subagents that all run in the background: your chat is never blocked, and when every subagent finishes, their results come back as a single consolidated turn. Kick off "research these five competitors in parallel" or "audit these three modules," then carry on with something else while a small fleet works. When it's all done, you get one clean summary instead of babysitting each one. (#49734 — @teknium1)
• •First-class coding Projects in the desktop app — The desktop app gained real, per-profile Projects — a sidebar of your codebases, a coding rail, a review pane, git worktree management, and agent-facing project tools, all backed by a proper project → repo → lane model. Instead of scattered chat sessions, your coding work is organized into projects the agent understands and can act on. It's the desktop turning into an actual coding cockpit. (#49037, #54385, #54517 — @OutThisLife)
• •Run Hermes at scale — scale-to-zero and drain coordination — The gateway can now go dormant when idle and quiesce cleanly before a restart, migration, or auto-update — without dropping in-flight conversations. A hosted or relay-only Hermes can scale to zero when nobody's talking to it and wake back up on demand, and disruptive lifecycle actions coordinate an external drain so nobody gets cut off mid-turn. Running Hermes for a team or as a hosted service just got a lot more production-grade. (#52243, #52937, #54824 — @teknium1, @benbarclay)

Hermes Agent v0.17.0 (v2026.6.19)

June 19, 2026

• •Hermes reaches iMessage — Photon Spectrum, no Mac relay required — There's now an iMessage platform plugin built on Photon's managed line pool. Run hermes photon login, authenticate with a device code, and Hermes can send and receive iMessage — no Mac sitting in a closet running a relay, no BlueBubbles bridge to babysit. It's positioned as the successor to BlueBubbles: free to start, nothing to self-host. If your friends and family live in the blue bubbles, Hermes lives there now too. (#32348, #42582, #44713 — @teknium1)
• •Raft — Hermes joins the Raft agent network as a gateway channel — A new bundled Raft platform adapter lets Hermes connect to Raft as an external agent through a wake-channel bridge. Set RAFT_PROFILE, run the bridge, and Raft can wake Hermes to handle messages — with a privacy-by-contract design where wake payloads carry only metadata (event IDs, timestamps), never message bodies. Another surface where Hermes can show up and do work. (#48210 — @xxchan, @teknium1)
• •A substantially more capable desktop app — v0.16.0 shipped the desktop app; v0.17.0 deepened it across dozens of PRs. Rebindable keyboard shortcuts, native OS notifications with per-type toggles, live subagent watch-windows that stream a delegated agent's activity into its own pane, a composer model selector with per-model presets, automatic RTL/bidi text direction, a resizable VS Code-themed terminal pane, per-thread composer drafts, and the ability to install any VS Code Marketplace theme directly into the app. The desktop is now a serious daily driver, not a preview. (#45866, #40660, #47060, #46959, #43292, #44596 — @OutThisLife, @teknium1)
• •Background / async subagents — delegate work and keep going — delegate_task(background=true) now dispatches a subagent that runs in the background and returns a handle immediately. You and the model keep working while it churns, and the full result re-enters the conversation as a new turn the moment it finishes. Kick off a long research dive or a multi-step build, then carry on with something else instead of sitting blocked waiting on it. (#40946, #46968 — @teknium1)
• •Edit images, not just generate them — image-to-image in `image_generate` — image_generate can now edit and transform a source image, not only create one from scratch. Pass an existing image and a prompt and it routes to the backend's edit endpoint (same tool, same pattern as video_generate), across every supported image provider. "Make this logo blue," "remove the background," "turn this sketch into a render" — all from the tool you already use. (#48705 — @teknium1)
• •Automation Blueprints — schedule things without learning cron — Pick an automation by name and Hermes asks you for what it needs — no cron syntax, no slot=value typing. One blueprint definition renders natively on every surface: a form in the dashboard, a slash command in the CLI/TUI/messenger, a conversation with the agent, an entry in the docs catalog. "Daily news briefing at 8am" becomes a thing you set up by answering questions, not by memorizing 0 8 * * *. (#41309 — @teknium1)
• •Cursor's Composer model, through your xAI Grok subscription — grok-composer-2.5-fast is now in the xAI OAuth model picker, with its context window reconciled to the full 200k. Composer is the fast coding model behind Cursor — and if you have an xAI Grok subscription, you can now point Hermes at it directly over OAuth, no separate API key. Your Grok plan, Hermes's agent loop, Composer's coding speed. (#47908, #6f89e17 — @teknium1)
• •Full profile builder in the dashboard — Build a complete Hermes profile from the browser — pick its model, choose its skills, attach its MCP servers — without hand-editing config.yaml. The dashboard also unified multi-profile management into one machine-wide view with a global profile switcher, so you manage every profile from a single place. (#39084, #44007 — @teknium1)

Hermes Agent v0.16.0 (2026.6.5) — The Surface Release

June 6, 2026

• •Hermes Desktop — a real native app, not a terminal wrapper — This is the headline. There's now a apps/desktop/ Electron application that installs like any other desktop app on macOS, Linux, and Windows, updates itself in place from inside the app, and gives you a polished GUI for everything Hermes does. You get a proper chat window with streaming, a session list you can archive and search, drag-and-drop files anywhere in the chat area, clipboard image paste, a Cmd+K command palette, and a model picker right in the status bar. If you've been telling friends "it's a CLI agent" and watching their eyes glaze over — now you can just send them an installer. None of this existed a week ago. (#20059, #35607, #37099, #37379, #38631 — @OutThisLife, @jquesnelle, @ethernet8023, @austinpickett, @benbarclay)
• •Run the desktop app against a remote Hermes — sign in with OAuth or username/password — The desktop app doesn't have to run Hermes locally. Point it at a remote Hermes gateway (your homelab, a hosted box, a teammate's server) and it connects over a secure WebSocket, authenticating with OAuth or a username/password login — no fiddling with --insecure flags or hand-copied session tokens. Each profile can target its own remote host, and you can run concurrent sessions across multiple profiles in one window with cross-profile @session links. The practical version: your laptop runs a thin GUI, the heavy agent runs wherever your API keys and compute live. (#37888, #38851, #39330, #39778 — @benbarclay, @OutThisLife, @teknium1)
• •The web dashboard is now a full admin panel — configure everything from the browser — The dashboard grew from "view your sessions" into a complete administration surface. There's a Channels page that sets up every gateway messaging platform (Telegram, Discord, Slack, etc.) from the browser, an admin panel for the MCP catalog with enable/disable toggles, credential management, webhook and hook creation, memory configuration, gateway controls, and a System page with check-before-update and one-click Debug Share. You no longer have to SSH in and edit config.yaml to wire up a new messaging channel or MCP server — it's all point-and-click now. (#36704, #36736, #37211, #38205, #38600 — @teknium1)
• •Hermes Desktop speaks Simplified Chinese — full 简体中文 in the chat GUI — The desktop app now ships a complete Simplified Chinese (简体中文) translation across every UI surface — the chat window itself, sidebar, settings, command center, cron, messaging, profiles, skills, agents, the lot. English stays the default; switch language in Appearance settings and the choice persists to your config (display.language). It's built on a proper typed i18n layer, so adding more languages from here is straightforward. (#38241 — @JimLiu)
• •Leaner default skill set — Hermes ships only what you actually need — The bundled skill set got a deliberate trim. Skills that were redundant or dead are gone (spotify — superseded by the native Spotify plugin's 7 tools; linear — superseded by hermes mcp install linear; kanban-codex-lane, debugging-hermes-tui-commands, a stale domain orphan, and several empty category markers). Heavier or niche skills moved from bundled to optional (the Baoyu creative set, dspy, subagent-driven-development, minecraft-modpack-server, pokemon-player, hermes-s6-container-supervision) — still one hermes skills install away, just not loaded by default. And a new environments: relevance gate keeps context-specific skills (kanban, docker/s6) out of the skills index for users who'll never use them, while still loading them on explicit request. The result: a smaller, sharper default skill list, less noise in the picker, and a lighter prompt. The curator can now prune unused built-in skills too (not just agent-created ones), with usage tracked for every skill. (#39028, #36701, #36228 — @teknium1)
• •NVIDIA/skills is now a built-in trusted skills tap — NVIDIA/skills joins OpenAI, Anthropic, and HuggingFace as a default trusted tap in the Skills Hub — discoverable, browsable, searchable, and auto-updating through the same pipeline. NVIDIA's verified skills for CUDA-X, AIQ, cuOpt and the rest of their product stack are one install away, with real category labels from the repo's skills.sh.json sidecar. (#34333 — @teknium1)
• •Quick Setup via Nous Portal — from install to first message in seconds — First-time setup was thinned down to two clear paths: Quick Setup (sign in with Nous Portal, get a model picker, start chatting immediately) or Full Setup (the detailed wizard for power users). hermes portal is now the human-readable alias that runs the full quick-setup Nous flow. The first-run menu explains the difference inline so newcomers aren't guessing. The goal: a brand-new user shouldn't need to read docs to send their first message. (#35723, #36227, #38449, #38465 — @teknium1, @kshitijk4poor)
• •Fuzzy model picker, everywhere — type a few letters, find your model — The model picker now does fuzzy search across the desktop app, web dashboard, TUI, and CLI. Type "v4fl" and deepseek-v4-flash surfaces; multi-endpoint providers are grouped under one row instead of cluttering the list with duplicates, and each row carries a description so you know what you're picking. The catalog refreshes hourly instead of daily, so new models show up the same day they launch. New this window: deepseek-v4-flash, MiniMax-M3 with 1M context, qwen3.7-plus. (#36928, #35227, #35756, #35659, #36214 — @kshitijk4poor, @teknium1)

Hermes Agent v0.15.1 (2026.5.29) — The Patch Release

May 29, 2026

• •Dashboard 401 reload loop fixed — In loopback mode the dashboard's identity probe (/api/auth/me) returns 401 by design, but v0.15.0's stale-token reload guard treated every 401 as a rotated session token and full-page-reloaded to pick up a fresh one. Every successful sibling call cleared the one-shot reload guard, so the page reload-looped forever (Firefox: "Navigated to /sessions" storm; Chrome: React re-render storm). Fix adds an allowUnauthorized opt-out to fetchJSON that skips only the loopback stale-token reload — 401 still throws so AuthWidget swallows it, gated-mode login_url redirects are unaffected. Closes #34206, #34202. (#30698 — @austinpickett)
• •Docker dashboard `--insecure` is now an explicit env opt-in, never derived from bind host — Previously the Docker entrypoint inferred --insecure when the dashboard bound to a non-loopback host. That conflated "I want LAN access" with "I want to disable the same-origin guard." The fix splits them: bind host is bind host, and disabling the dashboard's loopback auth requires an explicit HERMES_DASHBOARD_INSECURE=1. Existing setups that genuinely wanted insecure binding must now set the env var. (#34188, #34204 — @benbarclay)
• •MCP bare command resolution under Docker — MCP servers configured with bare commands (npx, npm, node) now resolve against /usr/local/bin so they actually launch inside the Docker image where those binaries live. v0.15.0 left these failing silently in containers when the agent's effective PATH didn't include the Node toolchain location. (#34186 — @benbarclay)
• •Skills page sidebar / source pills restored — A stale useMemo dependency in the new dashboard skills page collapsed the source pills and category sidebar to "All" only. Fixed; both surfaces now reflect the live catalog state. (#34194)
• •Kanban worker can be killed again — SIGTERM on a kanban worker was being absorbed by an intermediate process and the worker stayed running. Closes #28181. (#34045)
• •Full skills.sh catalog (858 → 19,932 entries) — The skills hub page was pulling a partial paginated catalog. The fetch now walks the sitemap, so all 19,932 skills.sh entries surface in the picker instead of just the first 858. (#34025)
• •`/api/auth/me` 401 no longer triggers reload loop in loopback mode — (#30698 — @austinpickett)
• •Skills page source pills + category sidebar restored — stale useMemo dep (#34194)

Hermes Agent v0.15.0 (2026.5.28) — The Velocity Release

May 28, 2026

• •The Big Refactor — `run_agent.py` is no longer 16,000 lines — The file at the heart of Hermes — the agent conversation loop — has been reduced from 16,083 lines to 3,821 (-76%), with the extracted code redistributed across 14 cohesive modules under agent/. Behavior is unchanged: every extraction keeps a thin forwarder on AIAgent, every test patch path still works, every external caller is compatible. The reason you care: future Hermes development moves faster, plugin authors can finally grep the codebase, and the file that took 90 seconds to load in your editor opens in a blink. (#27248)
• •Kanban grew into a real multi-agent platform — 104 PRs end to end — Triage auto-decomposes one task into a tree of sub-tasks. hermes kanban swarm creates a full Swarm v1 graph in one command — root, parallel workers, gated verifier, gated synthesizer, shared blackboard. Tasks support per-task model overrides (cheap models for boilerplate, expensive ones for hard sub-tasks), board-level default workdirs, per-task worktree paths and branches, scheduled start times, configurable claim TTL, retry fingerprinting, stale-task detection, respawn guards, and a drag-to-delete trash zone. Workers report through /workers/active, /runs/{id}, and /inspect endpoints. (#27572, #28443, #28364, #28394, #28462, #28384, #28467, #28455, #28452, #28432, #28468, #28420)
• •Cold-start perf wave keeps going — another second saved, 47% fewer per-turn function calls — Three new optimization rounds: defer openai._base_client import (-240ms / -17MB on every CLI invocation), hot-path optimizations cut 47% of per-conversation function calls (399k → 213k for 31-turn chat), defer compression-feasibility check (-170 to -290ms on every agent construction), adaptive subprocess polling (-195ms per tool call, 1+ second per turn). Termux cold start drops from 2.9s to 0.8s. hermes --version cold drops 63% (701ms → 258ms), flipping the head-to-head benchmark against Codex CLI from 5/11 wins to 6/11. (#28864, #28866, #28957, #29006, #29419, #30121, #30609, #31968)
• •`session_search` rebuilt — no LLM, no cost, 4,500× faster — The old session_search was an aux-LLM-powered tool that cost ~$0.30/call and took ~30 seconds to summarize three sessions, sometimes confabulating when the right session wasn't even in the FTS5 hit list. The new shape is one tool with three modes (discovery, scroll, browse) inferred from which args are set — no mode parameter, no aux-LLM, no config knob, no companion skill. Discovery is ~20ms instead of ~90s; scroll is ~1ms. Searching your past sessions for context is now free and instant. (#27590)
• •Promptware defense — Brainworm-class attacks blocked at three chokepoints — Inspired by recent Brainworm / Promptware Kill Chain research (Origin HQ, arxiv 2601.09625), Hermes now defends the context window against prompt-injection attacks that try to hijack the agent via tool output, recalled memory, or stored skills. Single source of truth (tools/threat_patterns.py) with ~15 new Brainworm/C2 patterns; recalled memory is scanned at load time; tool results get delimiter markers so a malicious file or remote service can't impersonate Hermes' own system content. Paired with a new security-guidance plugin that pattern-matches dangerous code writes. (#32269, #33131, #9151)
• •Bitwarden Secrets Manager — one bootstrap token replaces every per-provider API key — Stop keeping plaintext API keys in ~/.hermes/.env. Install Bitwarden Secrets Manager (bws auto-installs lazily on first use), point Hermes at it with one bootstrap token (BWS_ACCESS_TOKEN), and every credential you need comes from Bitwarden at startup. Rotate a key in the Bitwarden web app and the rotation actually takes effect — Bitwarden defaults to source-of-truth so its values overwrite matching env vars on startup. Flip secrets.bitwarden.override_existing: false to invert. EU Cloud and self-hosted Bitwarden server URLs supported. Detected credentials are now labeled with their source so you can see at a glance which keys came from Bitwarden vs. the local env. (#30035, #31378, #30364)
• •ntfy as the 23rd messaging platform — push notifications without an account — ntfy is the self-hostable push-notification service with no signup, no API key, just a topic URL. Hermes now adapts to it as a platform plugin (zero edits to core), so your agent can send you push notifications from any cron job, kanban task completion, or chat send_message — to your phone, your watch, your desktop, your homelab. (salvages #30625 → originally #4043) (#30867)
• •Skill bundles — `/<name>` loads multiple skills at once — A skill bundle is a named group of skills that loads them all together with one slash command. Set up your "writing day" bundle (humanizer + ideation + obsidian + youtube-content) and /writing-day activates all four for the session. Skills Hub now has health checks, a freshness badge, and a watchdog cron. Three new optional skills land: code-wiki (Karpathy's LLM-Wiki, persistent indexed dev wiki), openhands (delegate to OpenHands for parallel coding agents), and web-pentest (OWASP-style web pentest recipes). (#28373, #32345, #32240, #32261, #32265)

Hermes Agent v0.14.0 (2026.5.16)

May 16, 2026

• •xAI Grok via SuperGrok OAuth — and grok-4.3 jumps to a 1M context window — If you pay for SuperGrok, you can now use Grok inside Hermes by signing in with your xAI account — no API key, no separate billing. The wire-through also bumps grok-4.3 to a 1M token context window, so you can drop whole codebases or research corpora into a single prompt. Includes proper handling for entitlement errors and an SSH-to-tunnel docs page for when you're SSH'd into a remote box and need to complete the OAuth flow. (#26534, #26664, #26644, #26592)
• •OpenAI-compatible local proxy for OAuth providers — Run hermes proxy and you get a http://localhost:port endpoint that speaks the OpenAI API but is backed by whichever OAuth provider you're signed into — Claude Pro, ChatGPT Pro, SuperGrok. Now any tool that expects an OpenAI-compatible endpoint (Codex CLI, Aider, Cline, Continue, your custom scripts) just works with your existing subscription, no API key required. One subscription, every tool. (#25969)
• •`x_search` — first-class X (Twitter) search tool — The agent can now search X directly without installing a skill or wiring up a custom integration. Search the timeline, find threads, surface specific posts — straight from the chat. Auth with either your X OAuth login or an API key, whichever you have. (#26763)
• •Microsoft Teams — end-to-end — Hermes can now read messages from Teams and post back. The full Microsoft Graph stack lands together: auth + client foundation, a webhook listener that receives Teams events, a pipeline plugin runtime, and outbound delivery. Wire up the bot once, then chat to your agent from any Teams channel, DM, or group. (salvages of #21408–#21411) (#21922, #21969, #22007, #22024)
• •Debloating wave — lighter installs, less you don't use — A clean pip install hermes-agent used to pull down everything: every messaging adapter SDK, every image-gen SDK, every voice/TTS provider, whether you used them or not. Now those heavy backends (Slack / Matrix / Feishu / DingTalk adapters, hindsight client, codex app-server, Pixverse / Camofox / image-gen SDKs, voice/TTS providers) install automatically the first time you actually use them. The [all] extras drop everything covered by lazy-deps, the installer falls back through tiers when a wheel doesn't fit your platform, and a supply-chain advisory checker scans every install for unsafe versions. Faster installs, smaller disk footprint, fewer transitive vulnerabilities. (#24220, #24515, #25014, #25038, #25766, #21818)
• •`pip install hermes-agent && hermes` — Hermes Agent is now a real PyPI package. No more cloning the repo or running shell installers — one pip command and you're running. The wheel ships with the Ink TUI bundle and the shell launcher, so the full experience comes out of the box. (salvage of #26350) (#26593, #26148)
• •Cross-session 1h Claude prompt cache — When you use Claude through Anthropic, OpenRouter, or Nous Portal, the prompt prefix (system prompt, skills, memory) now caches for an hour across sessions. Start a /new session and the first response comes back faster and cheaper because the cache is still warm from your last session. Background memory review hits the cache too, so it's not paying full price every turn. (#23828, #25434, #24778)
• •180x faster `browser_console` evaluations — When the agent uses the browser tool to inspect a page or run JavaScript, those calls now share one persistent connection to Chrome instead of spinning up a new DevTools session every time. The difference is huge: things that used to take a couple of seconds per call return in milliseconds. Real-world page interactions feel instant. (#23226)

Hermes Agent v0.13.0 (2026.5.7) — The Tenacity Release

May 7, 2026

• •Multi-agent Kanban — delegate to an AI team that actually finishes — Spin up a durable board, drop tasks on it, and let multiple Hermes workers pick them up, hand off, and close them out. Heartbeats, reclaim, zombie detection, retry budgets, and a hallucination gate keep the team honest. One install, many kanbans. (#17805, #19653, #20232, #20332, #21330, #21183, #21214)
• •`/goal` — the agent doesn't forget what you asked it to do — Lock the agent onto a target and it stays on task across turns. The Ralph loop as a first-class primitive. (#18262, #18275, #21287)
• •Show it a video — new video_analyze tool for native video understanding on Gemini and compatible multimodal models. (@alt-glitch) (#19301)
• •Clone a voice — xAI Custom Voices lands as a TTS provider with voice cloning support. (@alt-glitch) (#18776)
• •Hermes speaks your language — static gateway + CLI messages translate to 7 locales: Chinese, Japanese, German, Spanish, French, Ukrainian, and Turkish. Docs site gains a Chinese (zh-Hans) locale. (#20231, #20329, #20467, #20474, #20430, #20431)
• •Google Chat — the 20th messaging platform — plus a generic platform-plugin hooks surface so third-party adapters drop in without touching core (IRC and Teams migrated). (#21306, #21331)
• •Sessions survive restarts — gateway bounces mid-agent, /update restarts, source-file reloads — conversations auto-resume when the gateway comes back. (#21192)
• •Security wave — 8 P0 closures — redaction ON by default, Discord role-allowlists guild-scoped (CVSS 8.1 cross-guild DM bypass closed), WhatsApp rejects strangers by default, TOCTOU windows closed across auth.json and MCP OAuth, browser enforces cloud-metadata SSRF floor, cron prompt-injection scans assembled skill content, hermes debug share redacts at upload. (#21193, #21241, #21291, #21176, #21194, #21228, #21350, #19318)

Hermes Agent v0.12.0 (2026.4.30)

April 30, 2026

• •Autonomous Curator — hermes curator runs as a background agent on the gateway's cron ticker (7-day cycle default). It grades your skill library, consolidates related skills, prunes dead ones, and writes per-run reports to logs/curator/run.json + REPORT.md. Archived skills are classified consolidated-vs-pruned via model + heuristic. Defense-in-depth gates protect bundled/hub skills from mutation. Unified under auxiliary.curator — pick the curator's model in hermes model, manage it from the dashboard. hermes curator status ranks skills by usage (most-used / least-used). (#17277, #17307, #17941, #17868, #18033)
• •Self-improvement loop — substantially upgraded — The background review fork (the core of Hermes' self-improvement: after each turn it decides what memories/skills to save or update) is now class-first (rubric-based rather than free-form), active-update biased (prefers the skill the agent just loaded), handles references//templates/ sub-files, and properly inherits the parent's live runtime (provider, model, credentials actually propagate). Restricted to memory + skills toolsets so it can't sprawl. Memory providers shut down cleanly. Prior-turn tool messages excluded from the summary so the fork sees a clean context. (#16026, #17213, #16099, #16569, #16204, #15057)
• •Skill integrations — major expansion — ComfyUI v5 with official CLI + REST + hardware-gated local install, moved from optional to built-in by default (#17610, #17631, #17734). TouchDesigner-MCP bundled by default, expanded with GLSL, post-FX, audio, geometry, and 9 new reference docs (#16753, #16624, #16768 — @kshitijk4poor + @SHL0MS). Humanizer skill ports a text-cleaner that strips AI-isms (#16787). claude-design HTML artifact skill + design-md (Google DESIGN.md spec) + airtable salvage + skill_manage edits in external_dirs + direct-URL skill install + /reload-skills slash command. (#16358, #14876, #16291, #17512, #16323, #17744)
• •LM Studio — first-class provider — upgraded from a custom-endpoint alias to a full-blown native provider: dedicated auth, hermes doctor checks, reasoning transport, live /models listing. (Salvage of @kshitijk4poor's #17061.) (#17102)
• •Four more new inference providers — GMI Cloud (first-class, salvage of #11955 — @isaachuangGMICLOUD), Azure AI Foundry with auto-detection, MiniMax OAuth with PKCE browser flow (salvage #15203), Tencent Tokenhub (salvage of #16860). (#16663, #15845, #17524, #16960)
• •Pluggable gateway platforms + Microsoft Teams — the gateway is now a plugin host. Drop-in messaging adapters live outside the core, and Microsoft Teams is the first plugin-shipped platform. (Salvage of #17664.) (#17751, #17828)
• •Tencent 元宝 (Yuanbao) — 18th messaging platform — native gateway adapter with text + media delivery. (#16298, #17424)
• •Spotify — native tools + bundled skill + wizard — 7 tools (play, search, queue, playlists, devices) behind PKCE OAuth, interactive setup wizard, bundled skill, surfacing in hermes tools, cron usage documented. (#15121, #15130, #15154, #15180)

Hermes Agent v0.11.0 (2026.4.23)

April 23, 2026

• •New Ink-based TUI — hermes --tui is now a full React/Ink rewrite of the interactive CLI, with a Python JSON-RPC backend (tui_gateway). Sticky composer, live streaming with OSC-52 clipboard support, stable picker keys, status bar with per-turn stopwatch and git branch, /clear confirm, light-theme preset, and a subagent spawn observability overlay. ~310 commits to ui-tui/ + tui_gateway/. (@OutThisLife + Teknium)
• •Transport ABC + Native AWS Bedrock — Format conversion and HTTP transport were extracted from run_agent.py into a pluggable agent/transports/ layer. AnthropicTransport, ChatCompletionsTransport, ResponsesApiTransport, and BedrockTransport each own their own format conversion and API shape. Native AWS Bedrock support via the Converse API ships on top of the new abstraction. (#10549, #13347, #13366, #13430, #13805, #13814 — @kshitijk4poor + Teknium)
• •Five new inference paths — Native NVIDIA NIM (#11774), Arcee AI (#9276), Step Plan (#13893), Google Gemini CLI OAuth (#11270), and Vercel ai-gateway with pricing + dynamic discovery (#13223 — @jerilynzheng). Plus Gemini routed through the native AI Studio API for better performance (#12674).
• •GPT-5.5 over Codex OAuth — OpenAI's new GPT-5.5 reasoning model is now available through your ChatGPT Codex OAuth, with live model discovery wired into the model picker so new OpenAI releases show up without catalog updates. (#14720)
• •QQBot — 17th supported platform — Native QQBot adapter via QQ Official API v2, with QR scan-to-configure setup wizard, streaming cursor, emoji reactions, and DM/group policy gating that matches WeCom/Weixin parity. (#9364, #11831)
• •Plugin surface expanded — Plugins can now register slash commands (register_command), dispatch tools directly (dispatch_tool), block tool execution from hooks (pre_tool_call can veto), rewrite tool results (transform_tool_result), transform terminal output (transform_terminal_output), ship image_gen backends, and add custom dashboard tabs. The bundled disk-cleanup plugin is opt-in by default as a reference implementation. (#9377, #10626, #10763, #10951, #12929, #12944, #12972, #13799, #14175)
• •`/steer` — mid-run agent nudges — /steer <prompt> injects a note that the running agent sees after its next tool call, without interrupting the turn or breaking prompt cache. For when you want to course-correct an agent in-flight. (#12116)
• •Shell hooks — Wire any shell script as a Hermes lifecycle hook (pre_tool_call, post_tool_call, on_session_start, etc.) without writing a Python plugin. (#13296)

Hermes Agent v0.10.0 (2026.4.16)

April 16, 2026

• •Nous Tool Gateway — Paid Nous Portal subscribers now get automatic access to web search (Firecrawl), image generation (FAL / FLUX 2 Pro), text-to-speech (OpenAI TTS), and browser automation (Browser Use) through their existing subscription. No separate API keys needed — just run hermes model, select Nous Portal, and pick which tools to enable. Per-tool opt-in via use_gateway config, full integration with hermes tools and hermes status, and the runtime correctly prefers the gateway even when direct API keys exist. Replaces the old hidden HERMES_ENABLE_NOUS_MANAGED_TOOLS env var with clean subscription-based detection. (#11206, based on work by @jquesnelle; docs: #11208)
• •@jquesnelle (emozilla) — Original Tool Gateway implementation (#10799), salvaged and shipped in this release

Hermes Agent v0.9.0 (v2026.4.13)

April 13, 2026

• •Local Web Dashboard — A new browser-based dashboard for managing your Hermes Agent locally. Configure settings, monitor sessions, browse skills, and manage your gateway — all from a clean web interface without touching config files or the terminal. The easiest way to get started with Hermes.
• •Fast Mode (`/fast`) — Priority processing for OpenAI and Anthropic models. Toggle /fast to route through priority queues for significantly lower latency on supported models (GPT-5.4, Codex, Claude). Expands across all OpenAI Priority Processing models and Anthropic's fast tier. (#6875, #6960, #7037)
• •iMessage via BlueBubbles — Full iMessage integration through BlueBubbles, bringing Hermes to Apple's messaging ecosystem. Auto-webhook registration, setup wizard integration, and crash resilience. (#6437, #6460, #6494)
• •WeChat (Weixin) & WeCom Callback Mode — Native WeChat support via iLink Bot API and a new WeCom callback-mode adapter for self-built enterprise apps. Streaming cursor, media uploads, markdown link handling, and atomic state persistence. Hermes now covers the Chinese messaging ecosystem end-to-end. (#7166, #7943)
• •Termux / Android Support — Run Hermes natively on Android via Termux. Adapted install paths, TUI optimizations for mobile screens, voice backend support, and the /image command work on-device. (#6834)
• •Background Process Monitoring (`watch_patterns`) — Set patterns to watch for in background process output and get notified in real-time when they match. Monitor for errors, wait for specific events ("listening on port"), or watch build logs — all without polling. (#7635)
• •Native xAI & Xiaomi MiMo Providers — First-class provider support for xAI (Grok) and Xiaomi MiMo, with direct API access, model catalogs, and setup wizard integration. Plus Qwen OAuth with portal request support. (#7372, #7855)
• •Pluggable Context Engine — Context management is now a pluggable slot via hermes plugins. Swap in custom context engines that control what the agent sees each turn — filtering, summarization, or domain-specific context injection. (#7464)

Hermes Agent v0.8.0 (v2026.4.8)

April 8, 2026

• •Background Process Auto-Notifications (`notify_on_complete`) — Background tasks can now automatically notify the agent when they finish. Start a long-running process (AI model training, test suites, deployments, builds) and the agent gets notified on completion — no polling needed. The agent can keep working on other things and pick up results when they land. (#5779)
• •Free Xiaomi MiMo v2 Pro on Nous Portal — Nous Portal now supports the free-tier Xiaomi MiMo v2 Pro model for auxiliary tasks (compression, vision, summarization), with free-tier model gating and pricing display in model selection. (#6018, #5880)
• •Live Model Switching (`/model` Command) — Switch models and providers mid-session from CLI, Telegram, Discord, Slack, or any gateway platform. Aggregator-aware resolution keeps you on OpenRouter/Nous when possible, with automatic cross-provider fallback when needed. Interactive model pickers on Telegram and Discord with inline buttons. (#5181, #5742)
• •Self-Optimized GPT/Codex Tool-Use Guidance — The agent diagnosed and patched 5 failure modes in GPT and Codex tool calling through automated behavioral benchmarking, dramatically improving reliability on OpenAI models. Includes execution discipline guidance and thinking-only prefill continuation for structured reasoning. (#6120, #5414, #5931)
• •Google AI Studio (Gemini) Native Provider — Direct access to Gemini models through Google's AI Studio API. Includes automatic models.dev registry integration for real-time context length detection across any provider. (#5577)
• •Inactivity-Based Agent Timeouts — Gateway and cron timeouts now track actual tool activity instead of wall-clock time. Long-running tasks that are actively working will never be killed — only truly idle agents time out. (#5389, #5440)
• •Approval Buttons on Slack & Telegram — Dangerous command approval via native platform buttons instead of typing /approve. Slack gets thread context preservation; Telegram gets emoji reactions for approval status. (#5890, #5975)
• •MCP OAuth 2.1 PKCE + OSV Malware Scanning — Full standards-compliant OAuth for MCP server authentication, plus automatic malware scanning of MCP extension packages via the OSV vulnerability database. (#5420, #5305)

Hermes Agent v0.7.0 (v2026.4.3)

April 3, 2026

• •Pluggable Memory Provider Interface — Memory is now an extensible plugin system. Third-party memory backends (Honcho, vector stores, custom DBs) implement a simple provider ABC and register via the plugin system. Built-in memory is the default provider. Honcho integration restored to full parity as the reference plugin with profile-scoped host/peer resolution. (#4623, #4616, #4355)
• •Same-Provider Credential Pools — Configure multiple API keys for the same provider with automatic rotation. Thread-safe least_used strategy distributes load across keys, and 401 failures trigger automatic rotation to the next credential. Set up via the setup wizard or credential_pool config. (#4188, #4300, #4361)
• •Camofox Anti-Detection Browser Backend — New local browser backend using Camoufox for stealth browsing. Persistent sessions with VNC URL discovery for visual debugging, configurable SSRF bypass for local backends, auto-install via hermes tools. (#4008, #4419, #4292)
• •Inline Diff Previews — File write and patch operations now show inline diffs in the tool activity feed, giving you visual confirmation of what changed before the agent moves on. (#4411, #4423)
• •API Server Session Continuity & Tool Streaming — The API server (Open WebUI integration) now streams tool progress events in real-time and supports X-Hermes-Session-Id headers for persistent sessions across requests. Sessions persist to the shared SessionDB. (#4092, #4478, #4802)
• •ACP: Client-Provided MCP Servers — Editor integrations (VS Code, Zed, JetBrains) can now register their own MCP servers, which Hermes picks up as additional agent tools. Your editor's MCP ecosystem flows directly into the agent. (#4705)
• •Gateway Hardening — Major stability pass across race conditions, photo media delivery, flood control, stuck sessions, approval routing, and compression death spirals. The gateway is substantially more reliable in production. (#4727, #4750, #4798, #4557)
• •Security: Secret Exfiltration Blocking — Browser URLs and LLM responses are now scanned for secret patterns, blocking exfiltration attempts via URL encoding, base64, or prompt injection. Credential directory protections expanded to .docker, .azure, .config/gh. Execute_code sandbox output is redacted. (#4483, #4360, #4305, #4327)

Hermes Agent v0.6.0 (v2026.3.30)

March 30, 2026

• •Profiles — Multi-Instance Hermes — Run multiple isolated Hermes instances from the same installation. Each profile gets its own config, memory, sessions, skills, and gateway service. Create with hermes profile create, switch with hermes -p <name>, export/import for sharing. Full token-lock isolation prevents two profiles from using the same bot credential. (#3681)
• •MCP Server Mode — Expose Hermes conversations and sessions to any MCP-compatible client (Claude Desktop, Cursor, VS Code, etc.) via hermes mcp serve. Browse conversations, read messages, search across sessions, and manage attachments — all through the Model Context Protocol. Supports both stdio and Streamable HTTP transports. (#3795)
• •Docker Container — Official Dockerfile for running Hermes Agent in a container. Supports both CLI and gateway modes with volume-mounted config. (#3668, closes #850)
• •Ordered Fallback Provider Chain — Configure multiple inference providers with automatic failover. When your primary provider returns errors or is unreachable, Hermes automatically tries the next provider in the chain. Configure via fallback_providers in config.yaml. (#3813, closes #1734)
• •Feishu/Lark Platform Support — Full gateway adapter for Feishu (飞书) and Lark with event subscriptions, message cards, group chat, image/file attachments, and interactive card callbacks. (#3799, #3817, closes #1788)
• •WeCom (Enterprise WeChat) Platform Support — New gateway adapter for WeCom (企业微信) with text/image/voice messages, group chats, and callback verification. (#3847)
• •Slack Multi-Workspace OAuth — Connect a single Hermes gateway to multiple Slack workspaces via OAuth token file. Each workspace gets its own bot token, resolved dynamically per incoming event. (#3903)
• •Telegram Webhook Mode & Group Controls — Run the Telegram adapter in webhook mode as an alternative to polling — faster response times and better for production deployments behind a reverse proxy. New group mention gating controls when the bot responds: always, only when @mentioned, or via regex triggers. (#3880, #3870)

Hermes Agent v0.5.0 (v2026.3.28)

March 28, 2026

• •Nous Portal now supports 400+ models — The Nous Research inference portal has expanded dramatically, giving Hermes Agent users access to over 400 models through a single provider endpoint
• •Hugging Face as a first-class inference provider — Full integration with HF Inference API including curated agentic model picker that maps to OpenRouter analogues, live /models endpoint probe, and setup wizard flow (#3419, #3440)
• •Telegram Private Chat Topics — Project-based conversations with functional skill binding per topic, enabling isolated workflows within a single Telegram chat (#3163)
• •Native Modal SDK backend — Replaced swe-rex dependency with native Modal SDK (Sandbox.create.aio + exec.aio), eliminating tunnels and simplifying the Modal terminal backend (#3538)
• •Plugin lifecycle hooks activated — pre_llm_call, post_llm_call, on_session_start, and on_session_end hooks now fire in the agent loop and CLI/gateway, completing the plugin hook system (#3542)
• •Improved OpenAI Model Reliability — Added GPT_TOOL_USE_GUIDANCE to prevent GPT models from describing intended actions instead of making tool calls, plus automatic stripping of stale budget warnings from conversation history that caused models to avoid tools across turns (#3528)
• •Nix flake — Full uv2nix build, NixOS module with persistent container mode, auto-generated config keys from Python source, and suffix PATHs for agent-friendliness (#20, #3274, #3061) by @alt-glitch
• •Supply chain hardening — Removed compromised litellm dependency, pinned all dependency version ranges, regenerated uv.lock with hashes, added CI workflow scanning PRs for supply chain attack patterns, and bumped deps to fix CVEs (#2796, #2810, #2812, #2816, #3073)

Hermes Agent v0.4.0 (v2026.3.23)

March 24, 2026

• •OpenAI-compatible API server — Expose Hermes as an /v1/chat/completions endpoint with a new /api/jobs REST API for cron job management, hardened with input limits, field whitelists, SQLite-backed response persistence, and CORS origin protection (#1756, #2450, #2456, #2451, #2472)
• •6 new messaging platform adapters — Signal, DingTalk, SMS (Twilio), Mattermost, Matrix, and Webhook adapters join Telegram, Discord, and WhatsApp. Gateway auto-reconnects failed platforms with exponential backoff (#2206, #1685, #1688, #1683, #2166, #2584)
• •@ context references — Claude Code-style @file and @url context injection with tab completions in the CLI (#2343, #2482)
• •4 new inference providers — GitHub Copilot (OAuth + token validation), Alibaba Cloud / DashScope, Kilo Code, and OpenCode Zen/Go (#1924, #1879 by @mchzimm, #1673, #1666, #1650)
• •MCP server management CLI — hermes mcp commands for installing, configuring, and authenticating MCP servers with full OAuth 2.1 PKCE flow (#2465)
• •Gateway prompt caching — Cache AIAgent instances per session, preserving Anthropic prompt cache across turns for dramatic cost reduction on long conversations (#2282, #2284, #2361)
