Search archived coding conversations and retrieve exact session revisions through the separately installed Agent Vault macOS app. Launches the app's existing MCP server through sh; reads the authorized archive through its local daemon. Vault handles storage-provider traffic. No bundled binaries, telemetry, credential-file reads, self-updater, or new background service.
Good to know before installing
Launches the separately installed Agent Vault app's own bundled Node MCP server (/Applications/Agent Vault.app or VAULT_APP_PATH) through sh with your VAULT_MCP_TOKEN binding token; that server code ships with the app, not in this repository. Its tools return archived conversations from Cursor, Codex, Claude Code and Hermes stored under ~/.vault (or VAULT_HOME) into the model's context, which is sent to your model provider. The app handles its own storage-provider traffic; the plugin adds no telemetry, network calls, credential-file reads or background service.
From the plugin's catalog listing.

Eatwise (外卖营养教练) — local-first Chinese dietary coach: deterministic meal nutrition reviews, personal daily energy/nutrient targets, and consented on-device profile and meal history through 9 MCP tools over a bundled open food database (TFND + USDA FNDDS). No network, no accounts, no payments; profile schema rejects name/phone/ID/medical fields by design. Engine pinned to an immutable git commit (cbc08f6) over npx stdio; Portable Agent Plugins v1 package (mcp.json + skills/), needs Node.js 22.5+ on PATH.
Good to know before installing
The engine's MCP tool descriptions and error messages are Chinese-only while the skills are English-first.

Discover, visualize, sanitize/export, and import community agents.md swarm configurations. Outputs abbreviated agent/persona/goal tables, renders ASCII topology diagrams (.svg and .png images + portable 7-bit copy-paste ASCII symbol blocks), generates rich themed swarm illustrations across 12 curated signature themes and orthogonal intensity levels (understated, normal, overstated) via Hermes default model and image_generate, exports sanitized agents.md files, and imports/reverts shared configs with on-screen file preview and best-effort import warnings; every import/revert asks for approval.
Good to know before installing
Myswarm_import/myswarm_revert replace the workspace AGENTS.md/agents.md (a file Hermes loads into every session's system prompt) after a Hermes approval prompt; choosing "always" approves all later imports. The import security check is a best-effort regex + model warning, not a security boundary — only import files you trust. Swarm file contents are sent to your configured model for parsing and PII scrubbing (also best-effort; review exports before sharing), and myswarm_visualize_image calls your configured image_generate provider (may cost credits). Adds a ~2.8k-character MySwarm guidance section to every session's system prompt. Writes myswarm-ascii.svg/.png and .md exports into the current folder (exports may overwrite an existing .md file there), plus a .agents.md.myswarm.orig sidecar, and keeps import backups under HERMES_HOME/plugin-data/myswarm/.

Guided Markdown and source-code review in Hermes Desktop — annotate passages or line-numbered code in a docked pane and send comment/question/change-request batches back to the agent; cards are offered automatically on delivered Markdown.
Good to know before installing
Reads any user-selected local .md/.markdown or source-code path (.py .sh .js .ts .tsx .c .h .cpp .go .rs .rb .yaml .yml .json .toml .sql, so config files such as config.yaml or auth.json are shown if you open them) up to 1 MB (symlink-resolved), writes only a <file>.redline.json sidecar beside it, and in Hermes Desktop chats the transform_llm_output hook appends a ::redline directive line to qualifying final agent responses; syntax highlighting uses Pygments in the local gateway host with plain-text fallback; no network beyond the local gateway, no credentials, no telemetry, no subprocesses; the pane polls the local backend every 3 s while open.

Context and control for any AI. Agent identity, scoped access, and proof across tools.
Good to know before installing
Skills-only package: its workflow skills steer the agent to Proofable's hosted MCP server at mcp.proofable.me (which you add yourself with `hermes mcp add … --auth oauth`) to check identity proofs and agent permissions, create wallet-signed proofs, and store, list or revoke secrets in Proofable's hosted vault, so secrets you store and proof/agent data go to Proofable; Hermes does not prompt before those MCP tools run unless you give the server a trust setting; the skills also suggest Proofable's own optional `proofable` CLI, which edits MCP/project config.

Hermes gateway integration for DeskRPG virtual offices, with profiles, kanban, cron, artifacts and NPC skill management. Install it through the DeskRPG setup wizard. Optional (off by default): when enabled by the operator, links the plugin into every profile so kanban workers and cron runs can save artifacts.
Good to know before installing
NPC skill management runs hermes skills/curator commands as background subprocesses per profile and edits that profile's skills, config.yaml and memory files; creating new review-policy kanban cards needs a review-policy API that upstream Hermes does not ship (the README points at the author's hermes-agent fork for it), and that feature stays inert on upstream.

A messenger-style roster for Hermes Desktop: one row per profile with its live sessions, per-profile colour, status lights, search, groups, multi-select and an Apropos beta that starts a new session already knowing the ones you picked.
Good to know before installing
A Desktop pane over all your local profiles: it reads each profile's sessions, cron jobs and settings through the app's own requests and, only when you click, deletes or archives sessions (deletes ask first), changes cron jobs or edits profile settings; Apropos starts a new session with a hidden pointer message naming the sessions you picked; no network calls or telemetry.

Ample

Ample (ample.computer) as native tools: deploy the websites and web apps Hermes builds to public HTTPS URLs, release changes to the same URLs, read build and runtime logs, list and delete apps; bundled skill ample:web-apps.
Good to know before installing
Maintained by Ample, the hosting service it deploys to; talks to Ample's API (https://api.ample.computer); on first use downloads the pinned Ample CLI 0.1.36 from Ample's release server (https://get.ample.computer/releases/0.1.36/, SHA-256 checked, never self-updated; cli_path uses your own binary instead) and runs it as a subprocess with an allowlisted environment and its crash reports off; ample_deploy uploads the folder it is given (home, Hermes home and credential directories refused) and writes ample.toml and .ample/ into it; with no AMPLE_CLIENT_ID/AMPLE_CLIENT_SECRET or AMPLE_TOKEN set, the first deploy signs up for a free Ample account (deleted after two days unless claimed) and saves its credential in Hermes's .env. A pre_tool_call hook sends every delete (scoped to that app) and the first publish of each folder to Hermes's approval gate; only folders the user has published, recorded in plugin state, skip it. No telemetry, no background processes.

Claude Code Theme
Community
Unofficial Claude Code-inspired theme for Hermes Desktop, with light and dark palettes, rounded composer and side-panel cards, softer sidebar and menus, and a context-window meter beside the model switcher.
Unofficial Claude Code-inspired theme for Hermes Desktop, with light and dark palettes, rounded composer and side-panel cards, softer sidebar and menus, and a context-window meter beside the model switcher. Not affiliated with, endorsed by, or sponsored by Anthropic or Claude Code.
Good to know before installing
Unofficial Claude Code lookalike theme; its stylesheet restyles native Desktop surfaces (user bubbles, composer, file panel, sidebar rows, dropdown menus) and hides the chat backdrop image; the context meter reads session.usage through the SDK; an opt-in accent setting uses setAccentOverride; no network calls of its own.

Proton Pass secret source: resolves pass://vault/item/field references (mapped source "protonpass") or every env-var-titled item of one vault (bulk source "protonpass_vault") into environment variables at startup through the user's own pass-cli, beside the built-in Bitwarden and 1Password sources, with a hermes protonpass setup/status/token/set/remove/sync/disable CLI. Stdlib-only, no Python deps.
Good to know before installing
When enabled, runs the user-installed pass-cli (argv only, allowlisted env, 30 s per call), which talks to Proton's API; a personal access token or AI-agent token is read from Hermes' env and passed only to the pass-cli login child's environment (never argv); writes a 0700 session dir under cache/protonpass and a 0600 value cache (cache_ttl_seconds: 0 disables); no self-update, no downloaded binaries, no telemetry, no background process.

Nerve is a supervisory nervous system for Hermes Agent with provider-neutral Jev, Laya, and OpenJev Reflex backends, evidence-backed Kanban supervision, context governance, token-budget trajectory control, and durable SSH workers.
Good to know before installing
The default Reflex backend is hosted Jev; with the default settings (enabled / admission_enabled on) each turn's user prompt (up to 12k characters) and redacted tool/result previews are sent to the configured Jev provider (OpenRouter Decisions / TypeSafe Jev) using your OPENROUTER_API_KEY or TYPESAFE_API_KEY, spending your credits on every turn. Laya and OpenJev can be configured as local/self-hosted backends. The operator-only nerve setup CLI can copy a local HermesContextBus checkout into HERMES_HOME/plugins/hermes-context-bus and runs hermes plugins enable/disable for that plugin when a profile is saved; the model cannot trigger this.

Step-by-step prompt builder for Hermes Desktop (F4): option cards per step with AI suggestions, then an AI-written final prompt sent to or placed in the composer through host.composer (Hermes Desktop 0.21.5+). Tuned for Claude Opus 5.5, Claude Sonnet 5.5 and GPT-6 Astra. AI calls go through its own auxiliary task (auxiliary.prompt_studio) via the dashboard plugin API; sends no temperature. No external network beyond the configured provider; preferences in ctx.storage.
Good to know before installing
On opening in an existing chat (default on, toggle in Studio Settings) it reads the last 8 user/assistant turns (plus any compaction summary) of that session from state.db, redacts secrets and sends up to 8k chars to the configured auxiliary model for a short summary used in step suggestions; draft and form answers go to the same auxiliary model; no other network.

Session pane for Hermes Desktop: Firefox-style session groups with project grouping, list/grid views, Ctrl+Scroll session cycling with a HUD, session-row styling and a built-in settings page. All timers are ctx-owned intervals disposed on unload (live-session poll ~30 s, session refresh ~45 s, project cache 60 s, activity expiry 30 s). The standalone full build in this repo (full/plugin.js, install.sh) is not part of this catalog entry. Contact: info@agantila.com.
Good to know before installing
SDK-only Desktop plugin: reads the local Hermes gateway through public RPCs (projects.tree, projects.list, session.list, session.active_list, session.context_breakdown) and, on your actions, writes through public RPCs (projects.create/update/add_folder/remove_folder/set_primary/set_active/delete, session.create, session.cwd.set, session.title, session.branch_stored, session.archive, session.close, session.delete); captures Ctrl+mouse-wheel across the app (browser zoom suppressed except over canvases, editors and zoomable images) to cycle sessions; settings and groups stay in the app's local plugin storage; no outbound network, no shell commands, no credentials, no self-update.

Native Discord Rich Presence (RPC) integration for Hermes Agent — real-time session, model, token, and tool tracking with local-only IPC.
Good to know before installing
Publishes your most recent session title (or, in full title mode, the workspace folder name), model name and token total to the local Discord client as Rich Presence every 3 s (visible to other Discord users); opt-in settings also publish the git branch and a "View Repository" button with the public github.com/gitlab.com remote URL (credentials, ports and other hosts stripped); reads ~/.hermes/state.db read-only; reads the active workspace's .git/HEAD and .git/config read-only to resolve repository and branch; on Linux may scan running Discord processes' environment via psutil to find XDG_RUNTIME_DIR; writes a small presence-ownership file in XDG_RUNTIME_DIR (or the system temp dir) and, under herdr, queries the local HERDR_SOCKET_PATH socket for pane focus.

@crontab: context references that explain a cron expression for the model: @crontab:"0 9 * * 1-5" (or a shortcut such as @crontab:@daily) attaches a plain-words reading ("At 09:00 on Monday through Friday."), each field on its own row, whether Hermes's /cron takes it as a cron expression (shortcuts, ? and 5#3 are not), its next five runs in Hermes's timezone setting worked out the way cron/jobs.py computes next runs, and notes on day of month OR day of week, * in the minute field, steps that do not divide the hour or day, days 29-31 and 7 as Sunday; the TUI and Desktop composer suggest examples and preview an expression as you type it. The reading comes from croniter, the library Hermes's scheduler uses.
Good to know before installing
Reads only the text of the reference itself, the system clock and Hermes's timezone setting (HERMES_TIMEZONE, else timezone from the loaded config through hermes_cli.config), using croniter (already installed with Hermes) and Python's standard library; no network, no files read or written, no subprocess, no credentials read, no cron job created, changed or run; the @crontab: reference and its explanation become part of the message sent to your model provider and saved in the session history; register() only adds the @crontab: reference provider.

Per-turn LLM routing: on each matching turn a TypeSafe Jev classifier call (api.typesafe.ai) receives turn-shape features plus the first 1200 chars of the last user message (shadow mode included) and labels it free/paid; high-confidence routine turns are downgraded to the provider's configured free rung, strategic mid-rung turns on Nous are escalated to the configured premium rung after a 2-token billed credit probe (Nous only, fail-closed). Fail-open, shadow-by-default, per-provider rungs from the user's lane2_config.json (leaderboard resolver script optional). Probe model id is fixed in code (z-ai/glm-5.3-flash).

Once you list models in ~/.hermes/jev/lane2_config.json, the first call of each matching turn sends message/tool counts and the first 1,200 characters of the last user message (send_excerpt, on by default) to TypeSafe Jev at api.typesafe.ai with your JEVI_API_KEY, in shadow mode as well as live; in live mode Jev's answer switches the request (and every later call of that turn, via an llm_execution wrapper) to the free, flash or premium model you configured on the same provider; with escalation set up on Nous it sends a 2-token billed ping to the Nous inference API with NOUS_API_KEY at most every 5 minutes; every turn appends a decision row (with that excerpt on routed turns) to ~/.hermes/jev/lane2-live.jsonl, which is never rotated.

DAG-based context engine that never loses a message — full-text search, semantic recall, assertion-backed evidence compilation, and pre-answer sufficiency gating
Good to know before installing
Replaces the context engine and stores every turn's full raw transcript in HERMES_HOME/trove.db with secret redaction OFF by default; with TROVE_EMBEDDING_PROVIDER=voyage, transcript text is sent to Voyage AI for embeddings; as a fallback it reads private AIAgent attributes read-only via frame inspection. No other network egress.

Cross-profile agent dispatch for Hermes Agent — 12 tools for agents talking to agents: async dispatch with SSE completion, synchronous multi-turn chat, model-selectable in-process subagents, a durable SQLite run ledger, fail-closed per-target model-route discovery, and host-owned bare LLM inference.
Good to know before installing
Sends task text and bearer tokens to the Hermes API servers you configure (plaintext HTTP permitted, warn-only); stores full dispatch text in a local SQLite ledger; delegate_subagent may use any provider credential you have configured.

One managed home for agent drafts: a per-session scratchpad of named buffers the agent edits in place instead of writing a new temp file per revision. Buffers live under plugin-data/devkit/, open in the Desktop code viewer, are promoted to real files only through write_file, and are removed when their chat is deleted. A Scratchpad tab beside Files groups chats by date like the chat sidebar; click a chat to open it, click a file to view or edit it in a workspace tab, and delete or clear drafts.
Good to know before installing
Adds a short placement rule (about 120 tokens) to each turn's user message; reads state.db read-only once an hour from a background thread to find deleted chats, and also removes folders idle longer than idle_days (default 90) using its own stamps; deletes only its own folders under plugin-data/devkit/; no network calls, credentials or third-party services.

Per-provider quota and balance readout in the Hermes desktop status bar. Per-provider chips with eye toggles, a popover with every quota window, reset times, balance and key-cap amounts, near-limit amber tint, a desktop notification per threshold crossing, and burn-rate projections (ETA to reset or depletion). Providers: OpenCode Go, OpenAI Codex, OpenRouter, plus Anthropic, GitHub Copilot, Nous, Z.AI, Kimi, MiniMax and DeepSeek when configured.
Good to know before installing
Resolves provider credentials read-only (Hermes account-usage helpers and profile secrets, else the profile's .env and the vendor CLI login files ~/.codex/auth.json, ~/.claude/.credentials.json and ~/.local/share/opencode/auth.json) and sends each only to that provider's usage endpoint; the GitHub Copilot check presents the VS Code / Copilot client identity.

NATS JetStream event bus: agents publish events (nats_publish), pull one batch (nats_fetch), and wake on subject matches — live-session watches or wake routes (config-declared or runtime-registered via jetstream_wake) with durable consumers, manual ack, an idempotent wake ledger and rate rails; an opt-in lifecycle tap mirrors Hermes events onto hermes.> subjects.
Good to know before installing
Connects only to the NATS servers in your own config (no third-party calls, no telemetry); the platform adapter holds persistent subscriptions and reconnect loops for the gateway's lifetime; token/nkey/user-pass secrets come from ${VAR} references read via the profile-scoped secret scope and a configured creds file is read from its path, never written or rotated; wake routes render event payloads into prompts that start gateway turns or fire an existing cron job (optionally under another named profile), the agent itself can add up to 16 durable wake routes with jetstream_wake that persist in plugin data across restarts (subject still limited to subscribe_allowed, no cron-job or cross-profile targets), and jetstream_watch injects matching events into the live session when allow_gateway_injection is on, so keep subscribe_allowed scoped to trusted publishers.

TypeSafe Jev semantic governance for Hermes' native Curator: classifies relationships between complete skill packages, produces content-hash-bound, fail-closed consolidation plans, and locally guards background destructive skill_manage calls while Hermes retains control of backups and mutations. A profile-scoped 60-second lifecycle debounce coalesces skill changes into dry refreshes.
Good to know before installing
No egress occurs by default; after allow_content_egress is explicitly enabled, redacted bounded skill content is sent to the configured TypeSafe, OpenRouter, or custom Jev endpoint and may spend provider credits. Automatic refreshes never apply mutations, and missing, stale, or incomplete evidence fails closed.

Choose models across Hermes profiles from a Dashboard tab: a per-profile picker built on host-supplied model data (SDK-authenticated GET /api/model/options), a preview of provider/model intent across every supported model-selection slot (main, delegation, auxiliary, judge, fallback, MoA, cron, plugin and specialist), and one-click apply or revert with presets. Main-slot preview shows intended provider/model, not the exact persisted diff; the exact diff is shown only after host readback.
Good to know before installing
Its apply route reads and edits the profiles' config.yaml (that is the plugin's function) through public seams only: POST /api/model/set for main and compatible auxiliary slots, and public hermes_cli.config load/save under the target home for other slots; credential presence checks use public profile-scoped secret helpers (agent.secret_scope), and profile discovery uses public hermes_constants. The plugin makes no direct third-party requests and opens no provider caches or pricing registries directly, but its browser tab does call the host's /api/model/* routes through the Dashboard SDK, and the host options route may itself initiate provider or pricing I/O even without an explicit refresh request, so reads are not guaranteed cache-only. It runs no shell commands or background processes and reports nothing. The private undo journal stores a full pre-change snapshot of each config it edits, which can contain sensitive fields including embedded credentials. Saved presets also persist reviewed change values, potentially including inline credentials or credential-bearing base URLs, in presets.json (0600) under get_hermes_home()/state/hermes-model-switcher/ (0700).

@b64: context references that decode encoded text for the model: @b64:<value> takes base64 (standard or URL-safe, padded or not), hex (0x48656c6c6f, 48:65:6c, \x48\x65), percent-encoding or a data: URI, told apart by the value's shape or picked with base64:, base64url:, hex: or url:, and attaches what it holds: text as text with control and invisible characters escaped, JSON pretty-printed, gzip and zlib inflated in memory (at most 1 MiB, one layer), and binary named by its format (PNG and GIF with their size, JPEG, PDF, ZIP, ELF, SQLite and more) with a hex dump of its first 128 bytes; notes point out a value that was cut short, padding that is off, a second layer of encoding and a JWT inside; the TUI and Desktop composer preview a value as you type it.
Good to know before installing
Reads only the text of the reference itself, using Python's base64, json, urllib.parse and zlib; nothing decoded is run, opened or saved; no network, no files read or written, no subprocess, no credentials read; the plugin keeps no copy of what it decodes, but the @b64: reference and the decoded contents become part of the message sent to your model provider and saved in the session history, so decode only values you are willing to share with it; register() only adds the @b64: reference provider.

Process hygiene for agent machines — finds the background processes your agent left behind (dev servers, tunnels, watchers, nohup jobs) using evidence signals (ppid=1 reparent, port listener via /proc/net/tcp{,6}, dev-server traits, TTL exceeded) and attributes them to the originating tool call via agent-ledger's ledger when present. Dry-run by default: nothing is killed until you write policy_mode=enforce; system daemons and host/VM management agents are exempt by name, a user-editable whitelist covers your real infrastructure, and each kill re-reads the cmdline first (SIGTERM, 2s, SIGKILL with PID-reuse check). stdlib-only, fails open.
Good to know before installing
Inside Hermes it only appends terminal commands that look like they start background work (first 300 characters, which can include inline secrets) to plugin-data/agent-janitor/spawns.jsonl, and reads agent-ledger's ledger.db read-only when present. Killing is a separate CLI you run yourself (janitor_cli.py sweep): after you write "enforce" to plugin-data/agent-janitor/policy_mode it sends SIGTERM then SIGKILL to every process re-parented to PID 1 for over a minute that is not on its built-in exempt list or your whitelist, whoever started it (for example a tmux server or a nohup'd hermes gateway), including other users' processes when run as root. Dry-run first; the dry-run list is the kill list.

Runtime guardrails, behavioral evaluation, and signed fleet admission for Hermes Agent: a versioned capability policy that blocks or requires approval for model tool calls, paired synthetic behavioral evaluation with no real side effects, and a signed local promotion gate that refuses a model whose evidence does not satisfy signed fleet policy. Hooks-only (no agent tools).
Good to know before installing
Adds approval prompts to tool calls by default (balanced mode): every MCP, connector or other-plugin tool, memory and skill writes, file reads outside the working and temp directories, and network-capable terminal/code commands go to Hermes's approval prompt; strict mode blocks them instead, and opt-in enforced fleet mode blocks all tool calls until the served model name matches the admitted one. The user-run `hermes antidote eval run` command sends synthetic prompts (and the API key you name) to the OpenAI-compatible endpoint you pass, as billed model calls (default suite up to ~170 requests); `model inspect hf:` queries huggingface.co; `fleet keygen` writes unencrypted Ed25519 private keys (mode 0600) to paths you choose.

Back up a Supabase project to your own S3, R2 or B2 bucket with the open-source backupdrill CLI (the Postgres database, plus Storage files once their S3 keys are set), then restore the snapshot into a throwaway Postgres in Docker to check it comes back.
Good to know before installing
A skill only, with no Python, hooks or server: it has the agent run npx -y backupdrill@2.7.1 in shell commands, which npx downloads from npm on first run. The CLI connects to the user's Supabase project and their own bucket, and a drill pulls a postgres image from Docker Hub. The connection string and bucket keys stay in a .env.backupdrill file the user fills in; each command loads it in a subshell and never prints it. Nothing is sent to BackupDrill.

Local System One / Laya Typed Decisions control plane for Hermes Agent. Sends bounded turn data to a configurable sidecar for reversible OFF/Shadow/Canary routing decisions, with explicit Canary acknowledgement and fail-open behavior.
Good to know before installing
Executes nothing and does not start the sidecar. In Shadow/Canary mode, Search and Model Tier may POST the current task plus bounded recent conversation context; Notification Shadow may POST the completed turn's final assistant response (up to 6000 chars) plus lifecycle metadata. The default sidecar URL is loopback 127.0.0.1:8787 but is user-configurable to any host and no auth header is added. Notification is observation-only: the plugin never sends a push/message/webhook and persists decision metadata, not raw response text. Its only request mutations, in acknowledged Canary mode on the first provider call of a turn, are removing web_search/web_extract tools for audited deterministic no-Web rules and (off by default) lowering reasoning_effort for gemini-3.8-flash-tiered on audited hard-fast rules. The sidecar (same repo, separate pip install, Apple-Silicon MLX/CoreML) is a text classifier that downloads a pinned Hugging Face model.

Routes selected Hermes auxiliary tasks (approval, MCP sampling, compression) through bounded Jev decision calls on OpenRouter instead of free-form chat prompts, failing open to the operator's own auxiliary provider for anything it cannot express as a decision.
Good to know before installing
Sends redacted approval prompts, MCP tool names and compression transcript blocks to openrouter.ai using your OpenRouter key (read-only); on any error approvals escalate to you, never auto-approve; the default decision_model is a moving alias, pin it.

Kanban Graph
Community
Live, read-only dependency graph of the Hermes kanban boards in Hermes Desktop: every board as a band, tasks as cards, dependencies as arrows with implied ones folded away.
Live, read-only dependency graph of the Hermes kanban boards in Hermes Desktop: every board as a band, tasks as cards, dependencies as arrows with implied ones folded away. Click a task to light up its whole lineage with runs, last failure and the running worker's latest tool calls; deep links open a task directly, and a stdlib CLI renders the same graph as a standalone HTML file. Zero API keys, zero model tokens.
Good to know before installing
Reads every kanban board database and, for running tasks, the assignee profile's state.db (the kanban worker session's latest assistant messages and tool-call arguments), read-only, and shows them in Desktop through its own local dashboard routes.
From the plugin's catalog listing.

Reduce Hermes tool-schema overhead and show selector savings in the dashboard.
Good to know before installing
Optional mode jev (off by default; needs TYPESAFE_API_KEY) sends each turn's request text and up to 32 candidate tool names and descriptions to TypeSafe (api.typesafe.ai); all other modes run locally. Optional user-run scripts can patch Hermes core on older Hermes and install a systemd user self-heal unit; the dashboard advisor edits the tool_slimmer section of config.yaml with a backup.

Security guardrails for Hermes tool calls: per-call authorization, so a prompt injection cannot make the agent do more than you allowed. Each call is checked against a signed, expiring permission slip (a warrant) before the handler runs, down to the arguments (file paths, search queries, spending limits), and every decision lands in a local audit log. Give cron jobs, delegate_task subagents and gateway users their own policy.
Good to know before installing
Hermes-tenuo is a no-op until a warrant is configured and blocks every tool call in a kanban worker that has no per-task warrant; it appends every tool call's name and full arguments to $HERMES_HOME/tenuo/audit.jsonl (disable with audit_log: false); when TENUO_CONNECT_TOKEN or TENUO_CONTROL_PLANE_URL are set, the bundled tenuo SDK (compiled Rust core) streams those decisions, including arguments, to that control plane.
From the plugin's catalog listing.
How to install
Install it. Hermes asks for any API keys it needs (this one needs TENUO_WARRANT, TENUO_SIGNING_KEY), then asks whether to turn it on.

Engineering rigor stack: poteto-mode orchestrator with 17 playbooks, plus how, architect, interrogate, swarm, unslop, and 46 other skills and principles.
Engineering rigor stack: poteto-mode orchestrator with 17 playbooks, plus how, architect, interrogate, swarm, unslop, and 46 other skills and principles.
Good to know before installing
Skills only, no tools or network calls of their own; when the user asks, the setup-pstack skill changes Hermes `delegation` model/provider/reasoning settings via `hermes config set`, the autopilot, shipping and babysit playbooks push and force-push the agent's own branches, squash-merge pull requests and arm hourly Hermes cron jobs to watch them, and the reflect skill files backlog issues in your team's tracker without asking per item.

Durable project ownership and bounded initiative management for Hermes fleets.
Good to know before installing
A `pre_llm_call` hook adds a project's saved rules, decisions and facts to turns of bots assigned to that project; objective checks run allowlisted local programs only at autonomy level 3+ and GitHub objectives shell out to your own `gh api`; it creates and edits Hermes Kanban tasks through Hermes' internal kanban modules (title/body/tenant written directly to kanban.db), keeps its own SQLite DB under `<Hermes home>/plugin-data/hermes-dockyard/`, and its optional HTTP API (`/stewardship/v1`, 127.0.0.1) stays closed until you set a bearer token.

Read before you install
Plugins run code inside your agent. Official plugins come from Nous Research's own repo. Community plugins are independent projects, so check the source, the permissions they ask for and any API keys they need. New to plugins? Start with skills vs plugins vs MCP.
