Skills System

Skills are on-demand knowledge documents the agent can load when needed. They follow a progressive disclosure pattern to minimize token usage and are compatible with the agentskills.io open standard.

All skills live in ~/.hermes/skills/ — the primary directory and source of truth. On fresh install, bundled skills are copied from the repo. Hub-installed and agent-created skills also go here. The agent can modify or delete any skill.

You can also point Hermes at external skill directories — additional folders scanned alongside the local one. See External Skill Directories below.

• Bundled Skills Catalog
• Official Optional Skills Catalog

Using Skills

Every installed skill is automatically available as a slash command:

# In the CLI or any messaging platform:
/gif-search funny cats
/axolotl help me fine-tune Llama 3 on my dataset
/github-pr-workflow create a PR for the auth refactor
/plan design a rollout for migrating our auth provider

# Just the skill name loads it and lets the agent ask what you need:
/excalidraw

The bundled plan skill is a good example. Running /plan [request] loads the skill's instructions, telling Hermes to inspect context if needed, write a markdown implementation plan instead of executing the task, and save the result under .hermes/plans/ relative to the active workspace/backend working directory.

You can also interact with skills through natural conversation:

hermes chat --toolsets skills -q "What skills do you have?"
hermes chat --toolsets skills -q "Show me the axolotl skill"

Progressive Disclosure

Skills use a token-efficient loading pattern:

Level 0: skills_list()           → [{name, description, category}, ...]   (~3k tokens)
Level 1: skill_view(name)        → Full content + metadata       (varies)
Level 2: skill_view(name, path)  → Specific reference file       (varies)

The agent only loads the full skill content when it actually needs it.

Platform-Specific Skills

Skills can restrict themselves to specific operating systems using the platforms field:

Value	Matches
macos	macOS (Darwin)
linux	Linux
windows	Windows

platforms: [macos]            # macOS only (e.g., iMessage, Apple Reminders, FindMy)
platforms: [macos, linux]     # macOS and Linux

When set, the skill is automatically hidden from the system prompt, skills_list(), and slash commands on incompatible platforms. If omitted, the skill loads on all platforms.

Skill output and media delivery

When a skill response (or any agent response) includes a bare absolute path to a media file — for example /home/user/screenshots/diagram.png — the gateway auto-detects it, strips it from the visible text, and delivers the file natively to the user's chat (Telegram photo, Discord attachment, etc.) instead of leaving the raw path in the message.

For audio specifically, the [[audio_as_voice]] directive promotes audio files to native voice-message bubbles on platforms that support them (Telegram, WhatsApp).

Forcing document-style delivery: [[as_document]]

Sometimes you want the opposite of inline preview: you want the file delivered as a downloadable attachment, not a re-compressed image bubble. The classic example is a high-resolution screenshot or chart — Telegram's sendPhoto recompresses it to ~200 KB at 1280 px, destroying readability. A 1-2 MB PNG sent via sendDocument keeps the original bytes intact.

If a response (or any text inside it — typically the last line) contains the literal directive [[as_document]], every media path extracted from that response is delivered as a document/file attachment rather than an image bubble:

Here is your rendered chart:

/home/user/.hermes/cache/chart-q4-2025.png

[[as_document]]

The directive is stripped before delivery, so users never see it. Granularity is intentionally all-or-nothing per response: emit [[as_document]] once and every image path in the same response is delivered as a document. This mirrors the scope of [[audio_as_voice]].

Use it from a skill when:

• You produce screenshots or charts the user needs as files (for editing in another tool, archiving, sharing intact).
• The default lossy preview would obscure detail (small text, pixel-accurate diagrams, color-sensitive renders).

Platforms without a separate document path (e.g. SMS) fall back to whatever attachment mechanism they have.

Conditional Activation (Fallback Skills)

Skills can automatically show or hide themselves based on which tools are available in the current session. This is most useful for fallback skills — free or local alternatives that should only appear when a premium tool is unavailable.

metadata:
  hermes:
    fallback_for_toolsets: [web]      # Show ONLY when these toolsets are unavailable
    requires_toolsets: [terminal]     # Show ONLY when these toolsets are available
    fallback_for_tools: [web_search]  # Show ONLY when these specific tools are unavailable
    requires_tools: [terminal]        # Show ONLY when these specific tools are available

Field	Behavior
fallback_for_toolsets	Skill is hidden when the listed toolsets are available. Shown when they're missing.
fallback_for_tools	Same, but checks individual tools instead of toolsets.
requires_toolsets	Skill is hidden when the listed toolsets are unavailable. Shown when they're present.
requires_tools	Same, but checks individual tools.

Example: The built-in duckduckgo-search skill uses fallback_for_toolsets: [web]. When you have FIRECRAWL_API_KEY set, the web toolset is available and the agent uses web_search — the DuckDuckGo skill stays hidden. If the API key is missing, the web toolset is unavailable and the DuckDuckGo skill automatically appears as a fallback.

Skills without any conditional fields behave exactly as before — they're always shown.

Secure Setup on Load

Skills can declare required environment variables without disappearing from discovery:

required_environment_variables:
  - name: TENOR_API_KEY
    prompt: Tenor API key
    help: Get a key from https://developers.google.com/tenor
    required_for: full functionality

When a missing value is encountered, Hermes asks for it securely only when the skill is actually loaded in the local CLI. You can skip setup and keep using the skill. Messaging surfaces never ask for secrets in chat — they tell you to use hermes setup or ~/.hermes/.env locally instead.

Once set, declared env vars are automatically passed through to execute_code and terminal sandboxes — the skill's scripts can use $TENOR_API_KEY directly. For non-skill env vars, use the terminal.env_passthrough config option. See Environment Variable Passthrough for details.

Skill Config Settings

Skills can also declare non-secret config settings (paths, preferences) stored in config.yaml:

metadata:
  hermes:
    config:
      - key: myplugin.path
        description: Path to the plugin data directory
        default: "~/myplugin-data"
        prompt: Plugin data directory path

Settings are stored under skills.config in your config.yaml. hermes config migrate prompts for unconfigured settings, and hermes config show displays them. When a skill loads, its resolved config values are injected into the context so the agent knows the configured values automatically.

See Skill Settings and Creating Skills — Config Settings for details.

External Skill Directories

If you maintain skills outside of Hermes — for example, a shared ~/.agents/skills/ directory used by multiple AI tools — you can tell Hermes to scan those directories too.

Add external_dirs under the skills section in ~/.hermes/config.yaml:

skills:
  external_dirs:
    - ~/.agents/skills
    - /home/shared/team-skills
    - ${SKILLS_REPO}/skills

Paths support ~ expansion and ${VAR} environment variable substitution.

How it works

• Read-only: External dirs are only scanned for skill discovery. When the agent creates or edits a skill, it always writes to ~/.hermes/skills/.
• Local precedence: If the same skill name exists in both the local dir and an external dir, the local version wins.
• Full integration: External skills appear in the system prompt index, skills_list, skill_view, and as /skill-name slash commands — no different from local skills.
• Non-existent paths are silently skipped: If a configured directory doesn't exist, Hermes ignores it without errors. Useful for optional shared directories that may not be present on every machine.

Example

~/.hermes/skills/               # Local (primary, read-write)
├── devops/deploy-k8s/
│   └── SKILL.md
└── mlops/axolotl/
    └── SKILL.md

~/.agents/skills/               # External (read-only, shared)
├── my-custom-workflow/
│   └── SKILL.md
└── team-conventions/
    └── SKILL.md

All four skills appear in your skill index. If you create a new skill called my-custom-workflow locally, it shadows the external version.

Skill Bundles

Skill bundles are tiny YAML files that group several skills under a single slash command. When you run /<bundle-name>, every skill listed in the bundle loads at once — useful when a particular task always benefits from the same set of skills together.

Quick example

# Create a bundle for backend feature work
hermes bundles create backend-dev \
  --skill github-code-review \
  --skill test-driven-development \
  --skill github-pr-workflow \
  -d "Backend feature work — review, test, PR workflow"

Then in the CLI or any gateway platform:

/backend-dev refactor the auth middleware

The agent receives all three skills loaded into one user message, with any text after the slash command attached as a user instruction.

YAML schema

Bundles live in ~/.hermes/skill-bundles/<slug>.yaml and look like this:

name: backend-dev
description: Backend feature work — review, test, PR workflow.
skills:
  - github-code-review
  - test-driven-development
  - github-pr-workflow
instruction: |
  Always start by writing failing tests, then implement.
  Open the PR through the standard workflow with co-author tags.

Fields:

• name (optional — defaults to the filename stem) — the bundle's display name. Normalized to a hyphen slug for the slash command (Backend Dev → /backend-dev).
• description (optional) — short text shown in /bundles and hermes bundles list.
• skills (required, non-empty list) — skill names or paths relative to your skills directory. Use the same identifier you'd pass to /<skill-name>.
• instruction (optional) — extra guidance prepended to the loaded skill content. Useful for codifying "how we always use these together."

Managing bundles

# List all installed bundles
hermes bundles list

# Inspect one bundle
hermes bundles show backend-dev

# Create a bundle interactively (omit --skill flags to enter them one per line)
hermes bundles create research

# Overwrite an existing bundle
hermes bundles create backend-dev --skill ... --force

# Delete a bundle
hermes bundles delete backend-dev

# Re-scan ~/.hermes/skill-bundles/ and report changes
hermes bundles reload

From inside a chat session, /bundles lists every installed bundle and its skills.

Behavior

• Bundles take precedence over individual skills when slugs collide. If you name a bundle research and you also have a skill called research, /research invokes the bundle. This is intentional — you opted into the bundle by naming it.
• Missing skills are skipped, not fatal. If a bundle lists skill-foo and you haven't installed it, the bundle still loads the skills that do resolve, and the agent gets a note listing what was skipped.
• Bundles work in every surface — interactive CLI, TUI, dashboard chat, and every gateway platform (Telegram, Discord, Slack, …) — because dispatch is centralized in the same place as individual skill commands.
• Bundles do not invalidate the prompt cache. They generate a fresh user message at invocation time, the same way /<skill-name> does — no system prompt mutation.

When bundles beat installing each skill manually

Use a bundle when:

• You always pair the same skills for a recurring task (/backend-dev, /release-prep, /incident-response).
• You want a one-character-shorter mental model than typing several /skill invocations in a row.
• You want to ship a team-wide "task profile" by checking the bundle YAML into a shared dotfiles repo and symlinking it into ~/.hermes/skill-bundles/.

A bundle is just a YAML alias — it doesn't install skills for you. The skills themselves must already be present (in ~/.hermes/skills/ or an external skill directory). Otherwise the bundle invocation just skips the missing ones.

Agent-Managed Skills (skill_manage tool)

The agent can create, update, and delete its own skills via the skill_manage tool. This is the agent's procedural memory — when it figures out a non-trivial workflow, it saves the approach as a skill for future reuse.

When the Agent Creates Skills

• After completing a complex task (5+ tool calls) successfully
• When it hit errors or dead ends and found the working path
• When the user corrected its approach
• When it discovered a non-trivial workflow

Actions

Action	Use for	Key params
create	New skill from scratch	name, content (full SKILL.md), optional category
patch	Targeted fixes (preferred)	name, old_string, new_string
edit	Major structural rewrites	name, content (full SKILL.md replacement)
delete	Remove a skill entirely	name
write_file	Add/update supporting files	name, file_path, file_content
remove_file	Remove a supporting file	name, file_path

팁

The patch action is preferred for updates — it's more token-efficient than edit because only the changed text appears in the tool call.

Skills Hub

Browse, search, install, and manage skills from online registries, skills.sh, direct well-known skill endpoints, and official optional skills.

github	openai/skills/k8s	Direct GitHub repo/path installs and custom taps.
clawhub, lobehub, claude-marketplace	Source-specific identifiers	Community or marketplace integrations.

Integrated hubs and registries

Hermes currently integrates with these skills ecosystems and discovery sources:

1. Official optional skills (official)

These are maintained in the Hermes repository itself and install with builtin trust.

• Catalog: Official Optional Skills Catalog
• Source in repo: optional-skills/
• Example:

hermes skills browse --source official
hermes skills install official/security/1password

2. skills.sh (skills-sh)

This is Vercel's public skills directory. Hermes can search it directly, inspect skill detail pages, resolve alias-style slugs, and install from the underlying source repo.

• Directory: skills.sh
• CLI/tooling repo: vercel-labs/skills
• Official Vercel skills repo: vercel-labs/agent-skills
• Example:

hermes skills search react --source skills-sh
hermes skills inspect skills-sh/vercel-labs/json-render/json-render-react
hermes skills install skills-sh/vercel-labs/json-render/json-render-react --force

3. Well-known skill endpoints (well-known)

This is URL-based discovery from sites that publish /.well-known/skills/index.json. It is not a single centralized hub — it is a web discovery convention.

• Example live endpoint: Mintlify docs skills index
• Reference server implementation: vercel-labs/skills-handler
• Example:

hermes skills search https://mintlify.com/docs --source well-known
hermes skills inspect well-known:https://mintlify.com/docs/.well-known/skills/mintlify
hermes skills install well-known:https://mintlify.com/docs/.well-known/skills/mintlify

4. Direct GitHub skills (github)

Hermes can install directly from GitHub repositories and GitHub-based taps. This is useful when you already know the repo/path or want to add your own custom source repo.

Default taps (browsable without any setup):

• openai/skills

• anthropics/skills

• huggingface/skills

• VoltAgent/awesome-agent-skills

• garrytan/gstack

• Example:

hermes skills install openai/skills/k8s
hermes skills tap add myorg/skills-repo

5. ClawHub (clawhub)

A third-party skills marketplace integrated as a community source.

• Site: clawhub.ai
• Hermes source id: clawhub

6. Claude marketplace-style repos (claude-marketplace)

Hermes supports marketplace repos that publish Claude-compatible plugin/marketplace manifests.

Known integrated sources include:

• anthropics/skills
• aiskillstore/marketplace

Hermes source id: claude-marketplace

7. LobeHub (lobehub)

Hermes can search and convert agent entries from LobeHub's public catalog into installable Hermes skills.

• Site: LobeHub
• Public agents index: chat-agents.lobehub.com
• Backing repo: lobehub/lobe-chat-agents
• Hermes source id: lobehub

8. Direct URL (url)

Install a single-file SKILL.md directly from any HTTP(S) URL — useful when an author hosts a skill on their own site (no hub listing, no GitHub path to type). Hermes fetches the URL, parses the YAML frontmatter, security-scans it, and installs.

• Hermes source id: url
• Identifier: the URL itself (no prefix needed)
• Scope: single-file SKILL.md only. Multi-file skills with references/ or scripts/ need a manifest and should be published via one of the other sources above.

hermes skills install https://sharethis.chat/SKILL.md
hermes skills install https://example.com/my-skill/SKILL.md --category productivity

Name resolution, in order:

1. name: field in the SKILL.md YAML frontmatter (recommended — every well-formed skill has one).
2. Parent directory name from the URL path (e.g. .../my-skill/SKILL.md → my-skill, or .../my-skill.md → my-skill), when it's a valid identifier (^[a-z][a-z0-9_-]*$).
3. Interactive prompt on a terminal with a TTY.
4. On non-interactive surfaces (the /skills install slash command inside the TUI, gateway platforms, scripts), a clean error pointing at the --name override.

# Frontmatter has no name and the URL slug is unhelpful — supply one:
hermes skills install https://example.com/SKILL.md --name sharethis-chat

# Or inside a chat session:
/skills install https://example.com/SKILL.md --name sharethis-chat

Trust level is always community — the same security scan runs as for every other source. The URL is stored as the install identifier, so hermes skills update re-fetches from the same URL automatically when you want to refresh.

Security scanning and --force

All hub-installed skills go through a security scanner that checks for data exfiltration, prompt injection, destructive commands, supply-chain signals, and other threats.

hermes skills inspect ... now also surfaces upstream metadata when available:

• repo URL
• skills.sh detail page URL
• install command
• weekly installs
• upstream security audit statuses
• well-known index/endpoint URLs

Use --force when you have reviewed a third-party skill and want to override a non-dangerous policy block:

hermes skills install skills-sh/anthropics/skills/pdf --force

Important behavior:

• --force can override policy blocks for caution/warn-style findings.
• --force does not override a dangerous scan verdict.
• Official optional skills (official/...) are treated as builtin trust and do not show the third-party warning panel.

Trust levels

Level	Source	Policy
builtin	Ships with Hermes	Always trusted
official	optional-skills/ in the repo	Builtin trust, no third-party warning
trusted	Trusted registries/repos such as openai/skills, anthropics/skills, huggingface/skills	More permissive policy than community sources
community	Everything else (skills.sh, well-known endpoints, custom GitHub repos, most marketplaces)	Non-dangerous findings can be overridden with --force; dangerous verdicts stay blocked

Update lifecycle

The hub now tracks enough provenance to re-check upstream copies of installed skills:

hermes skills check          # Report which installed hub skills changed upstream
hermes skills update         # Reinstall only the skills with updates available
hermes skills update react   # Update one specific installed hub skill

This uses the stored source identifier plus the current upstream bundle content hash to detect drift.

GitHub rate limits

Skills hub operations use the GitHub API, which has a rate limit of 60 requests/hour for unauthenticated users. If you see rate-limit errors during install or search, set GITHUB_TOKEN in your .env file to increase the limit to 5,000 requests/hour. The error message includes an actionable hint when this happens.

Publishing a custom skill tap

If you want to share a curated set of skills — for your team, your org, or publicly — you can publish them as a tap: a GitHub repository other Hermes users add with hermes skills tap add <owner/repo>. No server, no registry sign-up, no release pipeline. Just a directory of SKILL.md files.

Repo layout

A tap is any GitHub repo (public or private — private needs GITHUB_TOKEN) laid out like this:

owner/repo
├── skills/                       # default path; configurable per-tap
│   ├── my-workflow/
│   │   ├── SKILL.md              # required
│   │   ├── references/           # optional supporting files
│   │   ├── templates/
│   │   └── scripts/
│   ├── another-skill/
│   │   └── SKILL.md
│   └── third-skill/
│       └── SKILL.md
└── README.md                     # optional but helpful

Rules:

• Each skill lives in its own directory under the tap's root path (default skills/).
• The directory name becomes the skill's install slug.
• Each skill directory must contain a SKILL.md with standard SKILL.md frontmatter (name, description, plus optional metadata.hermes.tags, version, author, platforms, metadata.hermes.config).
• Subdirectories like references/, templates/, scripts/, assets/ are downloaded alongside SKILL.md at install time.
• Skills whose directory name starts with . or _ are ignored.

Hermes discovers skills by listing every subdirectory of the tap path and probing each for SKILL.md.

Minimal tap example

my-org/hermes-skills
└── skills/
    └── deploy-runbook/
        └── SKILL.md

skills/deploy-runbook/SKILL.md:

---
name: deploy-runbook
description: Our deployment runbook — services, rollback, Slack channels
version: 1.0.0
author: My Org Platform Team
metadata:
  hermes:
    tags: [deployment, runbook, internal]
---

# Deploy Runbook

Step 1: ...

After pushing that to GitHub, any Hermes user can subscribe and install:

hermes skills tap add my-org/hermes-skills
hermes skills search deploy
hermes skills install my-org/hermes-skills/deploy-runbook

Non-default paths

If your skills don't live under skills/ (common when you're adding a skills/ subtree to an existing project), edit the tap entry in ~/.hermes/.hub/taps.json:

{
  "taps": [
    {"repo": "my-org/platform-docs", "path": "internal/skills/"}
  ]
}

The hermes skills tap add CLI defaults new taps to path: "skills/"; edit the file directly if you need a different path. hermes skills tap list shows the effective path per tap.

Installing individual skills directly (without adding a tap)

Users can also install a single skill from any public GitHub repo without adding the whole repo as a tap:

hermes skills install owner/repo/skills/my-workflow

Useful when you want to share one skill without asking the user to subscribe to your whole registry.

Trust levels for taps

New taps are assigned community trust by default. Skills installed from them run through the standard security scan and show the third-party warning panel on first install. If your org or a widely-trusted source should get higher trust, add its repo to TRUSTED_REPOS in tools/skills_hub.py (requires a Hermes core PR).

Tap management

hermes skills tap list                                # show all configured taps
hermes skills tap add myorg/skills-repo               # add (default path: skills/)
hermes skills tap remove myorg/skills-repo            # remove

Inside a running session:

/skills tap list
/skills tap add myorg/skills-repo
/skills tap remove myorg/skills-repo

Taps are stored in ~/.hermes/.hub/taps.json (created on demand).

Bundled skill updates (hermes skills reset)

Hermes ships with a set of bundled skills in skills/ inside the repo. On install and on every hermes update, a sync pass copies those into ~/.hermes/skills/ and records a manifest at ~/.hermes/skills/.bundled_manifest mapping each skill name to the content hash at the time it was synced (the origin hash).

On each sync, Hermes recomputes the hash of your local copy and compares it to the origin hash:

• Unchanged → safe to pull upstream changes, copy the new bundled version in, record the new origin hash.
• Changed → treated as user-modified and skipped forever, so your edits never get stomped.

The protection is good, but it has one sharp edge. If you edit a bundled skill and then later want to abandon your changes and go back to the bundled version by just copy-pasting from ~/.hermes/hermes-agent/skills/, the manifest still holds the old origin hash from whenever the last successful sync ran. Your fresh copy-paste contents (current bundled hash) won't match that stale origin hash, so sync keeps flagging it as user-modified.

hermes skills reset is the escape hatch:

# Safe: clears the manifest entry for this skill. Your current copy is preserved,
# but the next sync re-baselines against it so future updates work normally.
hermes skills reset google-workspace

# Full restore: also deletes your local copy and re-copies the current bundled
# version. Use this when you want the pristine upstream skill back.
hermes skills reset google-workspace --restore

# Non-interactive (e.g. in scripts or TUI mode) — skip the --restore confirmation.
hermes skills reset google-workspace --restore --yes

The same command works in chat as a slash command:

/skills reset google-workspace
/skills reset google-workspace --restore

Profiles

Each profile has its own .bundled_manifest under its own HERMES_HOME, so hermes -p coder skills reset <name> only affects that profile.

Slash commands (inside chat)

All the same commands work with /skills:

/skills browse
/skills search react --source skills-sh
/skills search https://mintlify.com/docs --source well-known
/skills inspect skills-sh/vercel-labs/json-render/json-render-react
/skills install openai/skills/skill-creator --force
/skills check
/skills update
/skills reset google-workspace
/skills list

Official optional skills still use identifiers like official/security/1password and official/migration/openclaw-migration.
