--- title: "Skills" sidebarTitle: "Skills" summary: "Skills teach your agent how to use tools. Learn how they load, how precedence works, and how to configure gating, allowlists, and environment injection." read_when: - Adding or modifying skills - Changing skill gating, allowlists, or load rules - Understanding skill precedence and snapshot behavior --- Skills are markdown instruction files that teach the agent how and when to use tools. Each skill lives in a directory containing a `SKILL.md` file with YAML frontmatter and a markdown body. OpenClaw loads bundled skills plus any local overrides, and filters them at load time based on environment, config, and binary presence. Build and test a custom skill from scratch. Review and approve agent-drafted skill proposals. Full `skills.*` config schema and agent allowlists. Browse and install community skills. ## Loading order OpenClaw loads from these sources, **highest precedence first**. When the same skill name appears in multiple places, the highest source wins. | Priority | Source | Path | | ----------- | ---------------------- | --------------------------------------- | | 1 — highest | Workspace skills | `/skills` | | 2 | Project agent skills | `/.agents/skills` | | 3 | Personal agent skills | `~/.agents/skills` | | 4 | Managed / local skills | `~/.openclaw/skills` | | 5 | Bundled skills | shipped with the install | | 6 — lowest | Extra directories | `skills.load.extraDirs` + plugin skills | Skill roots support grouped layouts. OpenClaw discovers a skill whenever `SKILL.md` appears anywhere under a configured root: ```text /skills/research/SKILL.md ✓ found as "research" /skills/personal/research/SKILL.md ✓ also found as "research" ``` The folder path is for organization only. The skill's name, slash command, and allowlist key all come from the `name` frontmatter field (or the directory name when `name` is missing). Codex CLI's native `$CODEX_HOME/skills` directory is **not** an OpenClaw skill root. Use `openclaw migrate plan codex` to inventory those skills, then `openclaw migrate codex` to copy them into your OpenClaw workspace. ## Per-agent vs shared skills In multi-agent setups, each agent has its own workspace. Use the path that matches your desired visibility: | Scope | Path | Visible to | | -------------- | ---------------------------- | --------------------------- | | Per-agent | `/skills` | Only that agent | | Project-agent | `/.agents/skills` | Only that workspace's agent | | Personal-agent | `~/.agents/skills` | All agents on this machine | | Shared managed | `~/.openclaw/skills` | All agents on this machine | | Extra dirs | `skills.load.extraDirs` | All agents on this machine | ## Agent allowlists Skill **location** (precedence) and skill **visibility** (which agent can use it) are separate controls. Use allowlists to restrict which skills an agent sees, regardless of where they are loaded from. ```json5 { agents: { defaults: { skills: ["github", "weather"], // shared baseline }, list: [ { id: "writer" }, // inherits github, weather { id: "docs", skills: ["docs-search"] }, // replaces defaults entirely { id: "locked-down", skills: [] }, // no skills ], }, } ``` - Omit `agents.defaults.skills` to leave all skills unrestricted by default. - Omit `agents.list[].skills` to inherit `agents.defaults.skills`. - Set `agents.list[].skills: []` to expose no skills for that agent. - A non-empty `agents.list[].skills` list is the **final** set — it does not merge with defaults. - The effective allowlist applies across prompt building, slash-command discovery, sandbox sync, and skill snapshots. ## Plugins and skills Plugins can ship their own skills by listing `skills` directories in `openclaw.plugin.json` (paths relative to the plugin root). Plugin skills load when the plugin is enabled — for example, the browser plugin ships a `browser-automation` skill for multi-step browser control. Plugin skill directories merge at the same low-precedence level as `skills.load.extraDirs`, so a same-named bundled, managed, agent, or workspace skill overrides them. Gate them via `metadata.openclaw.requires.config` on the plugin's config entry. See [Plugins](/tools/plugin) and [Tools](/tools) for the full plugin system. ## Skill Workshop [Skill Workshop](/tools/skill-workshop) is a proposal queue between the agent and your active skill files. When the agent spots reusable work, it drafts a proposal instead of writing directly to `SKILL.md`. You review and approve before anything changes. ```bash openclaw skills workshop list openclaw skills workshop inspect openclaw skills workshop apply ``` See [Skill Workshop](/tools/skill-workshop) for the full lifecycle, CLI reference, and configuration. ## Installing from ClawHub [ClawHub](https://clawhub.ai) is the public skills registry. Use `openclaw skills` commands for install and update, or the `clawhub` CLI for publish and sync. | Action | Command | | ---------------------------------- | ------------------------------------------------------ | | Install a skill into the workspace | `openclaw skills install ` | | Install from a Git repository | `openclaw skills install git:owner/repo@ref` | | Install a local skill directory | `openclaw skills install ./path/to/skill --as my-tool` | | Install for all local agents | `openclaw skills install --global` | | Update all workspace skills | `openclaw skills update --all` | | Update a shared managed skill | `openclaw skills update --global` | | Update all shared managed skills | `openclaw skills update --all --global` | | Verify a skill's trust envelope | `openclaw skills verify ` | | Print the generated Skill Card | `openclaw skills verify --card` | | Publish / sync via ClawHub CLI | `clawhub sync --all` | `openclaw skills install` installs into the active workspace `skills/` directory by default. Add `--global` to install into the shared `~/.openclaw/skills` directory, visible to all local agents unless agent allowlists narrow it. Git and local installs expect `SKILL.md` at the source root. The slug comes from `SKILL.md` frontmatter `name` when valid, then falls back to the directory or repository name. Use `--as ` to override. `openclaw skills update` tracks ClawHub installs only — reinstall Git or local sources to refresh them. `openclaw skills verify ` asks ClawHub for the skill's `clawhub.skill.verify.v1` trust envelope. Installed ClawHub skills verify against the version and registry recorded in `.clawhub/origin.json`. ClawHub skill pages expose the latest security scan state before install, with detail pages for VirusTotal, ClawScan, and static analysis. The command exits non-zero when ClawHub marks verification as failed. Publishers recover false positives through the ClawHub dashboard or `clawhub skill rescan `. Gateway clients that need non-ClawHub delivery can stage a zip skill archive with `skills.upload.begin`, `skills.upload.chunk`, and `skills.upload.commit`, then install with `skills.install({ source: "upload", ... })`. This path is off by default and requires `skills.install.allowUploadedArchives: true` in `openclaw.json`. Normal ClawHub installs never need that setting. ## Security Treat third-party skills as **untrusted code**. Read them before enabling. Prefer sandboxed runs for untrusted inputs and risky tools. See [Sandboxing](/gateway/sandboxing) for agent-side controls. Workspace, project-agent, and extra-dir skill discovery only accepts skill roots whose resolved realpath stays inside the configured root, unless `skills.load.allowSymlinkTargets` explicitly trusts a target root. Managed `~/.openclaw/skills` and personal `~/.agents/skills` may contain symlinked skill folders, but every `SKILL.md` realpath must still stay inside its resolved skill directory. Gateway-backed skill installs (onboarding, Skills settings UI) run the built-in dangerous-code scanner before executing installer metadata. `critical` findings block by default; `suspicious` findings warn only. `openclaw skills install ` downloads a ClawHub skill folder directly and does not use the installer-metadata scanner. `skills.entries.*.env` and `skills.entries.*.apiKey` inject secrets into the **host** process for that agent turn only — not into the sandbox. Keep secrets out of prompts and logs. For the broader threat model and security checklists, see [Security](/gateway/security). ## SKILL.md format Every skill needs at minimum a `name` and `description` in the frontmatter: ```markdown --- name: image-lab description: Generate or edit images via a provider-backed image workflow --- When the user asks to generate an image, use the `image_generate` tool... ``` OpenClaw follows the [AgentSkills](https://agentskills.io) spec. The frontmatter parser supports **single-line keys only** — `metadata` must be a single-line JSON object. Use `{baseDir}` in the body to reference the skill folder path. ### Optional frontmatter keys URL shown as "Website" in the macOS Skills UI. Also supported via `metadata.openclaw.homepage`. When `true`, the skill is exposed as a user-invocable slash command. When `true`, OpenClaw keeps the skill's instructions out of the agent's normal prompt. The skill is still available as a slash command when `user-invocable` is also `true`. When set to `tool`, the slash command bypasses the model and dispatches directly to a registered tool. Tool name to invoke when `command-dispatch: tool` is set. For tool dispatch, forwards the raw args string to the tool with no core parsing. The tool receives `{ command: "", commandName: "", skillName: "" }`. ## Gating OpenClaw filters skills at load time using `metadata.openclaw` (single-line JSON in the frontmatter). A skill with no `metadata.openclaw` block is always eligible unless explicitly disabled. ```markdown --- name: image-lab description: Generate or edit images via a provider-backed image workflow metadata: { "openclaw": { "requires": { "bins": ["uv"], "env": ["GEMINI_API_KEY"], "config": ["browser.enabled"] }, "primaryEnv": "GEMINI_API_KEY", }, } --- ``` When `true`, always include the skill and skip all other gates. Optional emoji shown in the macOS Skills UI. Optional URL shown as "Website" in the macOS Skills UI. Platform filter. When set, the skill is only eligible on the listed OSes. Each binary must exist on `PATH`. At least one binary must exist on `PATH`. Each env var must exist in the process or be provided via config. Each `openclaw.json` path must be truthy. Env var name associated with `skills.entries..apiKey`. Optional installer specs used by the macOS Skills UI (brew / node / go / uv / download). Legacy `metadata.clawdbot` blocks are still accepted when `metadata.openclaw` is absent, so older installed skills keep their dependency gates and installer hints. New skills should use `metadata.openclaw`. ### Installer specs Installer specs tell the macOS Skills UI how to install a dependency: ```markdown --- name: gemini description: Use Gemini CLI for coding assistance and Google search lookups. metadata: { "openclaw": { "emoji": "♊️", "requires": { "bins": ["gemini"] }, "install": [ { "id": "brew", "kind": "brew", "formula": "gemini-cli", "bins": ["gemini"], "label": "Install Gemini CLI (brew)", }, ], }, } --- ``` - When multiple installers are listed, the gateway picks one preferred option (brew when available, otherwise node). - If all installers are `download`, OpenClaw lists each entry so you can see all available artifacts. - Specs can include `os: ["darwin"|"linux"|"win32"]` to filter by platform. - Node installs honor `skills.install.nodeManager` in `openclaw.json` (default: npm; options: npm / pnpm / yarn / bun). This only affects skill installs; the Gateway runtime should still be Node. - Gateway installer preference: Homebrew → uv → configured node manager → go → download. - **Homebrew:** OpenClaw does not auto-install Homebrew or translate brew formulas into system package commands. In Linux containers without `brew`, brew-only installers are hidden; use a custom image or install the dependency manually. - **Go:** if `go` is missing and `brew` is available, the gateway installs Go via Homebrew first and sets `GOBIN` to Homebrew's `bin`. - **Download:** `url` (required), `archive` (`tar.gz` | `tar.bz2` | `zip`), `extract` (default: auto when archive detected), `stripComponents`, `targetDir` (default: `~/.openclaw/tools/`). `requires.bins` is checked on the **host** at skill load time. If an agent runs in a sandbox, the binary must also exist **inside the container**. Install it via `agents.defaults.sandbox.docker.setupCommand` or a custom image. `setupCommand` runs once after container creation and requires network egress, a writable root FS, and a root user in the sandbox. ## Config overrides Toggle and configure bundled or managed skills under `skills.entries` in `~/.openclaw/openclaw.json`: ```json5 { skills: { entries: { "image-lab": { enabled: true, apiKey: { source: "env", provider: "default", id: "GEMINI_API_KEY" }, env: { GEMINI_API_KEY: "GEMINI_KEY_HERE" }, config: { endpoint: "https://example.invalid", model: "nano-pro", }, }, peekaboo: { enabled: true }, sag: { enabled: false }, }, }, } ``` `false` disables the skill even when bundled or installed. The `coding-agent` bundled skill is opt-in — set `skills.entries.coding-agent.enabled: true` and ensure one of `claude`, `codex`, `opencode`, or another supported CLI is installed and authenticated. Convenience field for skills that declare `metadata.openclaw.primaryEnv`. Supports a plaintext string or a SecretRef object. Environment variables injected for the agent run. Only injected when the variable is not already set in the process. Optional bag for custom per-skill configuration fields. Optional allowlist for **bundled** skills only. When set, only bundled skills in the list are eligible. Managed and workspace skills are unaffected. Config keys match the **skill name** by default. If a skill defines `metadata.openclaw.skillKey`, use that key under `skills.entries`. Quote hyphenated names: JSON5 allows quoted keys. ## Environment injection When an agent run starts, OpenClaw: OpenClaw resolves the effective skill list for the agent, applying gating rules, allowlists, and config overrides. `skills.entries..env` and `skills.entries..apiKey` are applied to `process.env` for the duration of the run. Eligible skills are compiled into a compact XML block and injected into the system prompt. After the run ends, the original environment is restored. Env injection is scoped to the **host** agent run, not the sandbox. Inside a sandbox, `env` and `apiKey` have no effect. See [Skills config](/tools/skills-config#sandboxed-skills-and-env-vars) for how to pass secrets into sandboxed runs. For the bundled `claude-cli` backend, OpenClaw also materializes the same eligible skill snapshot as a temporary Claude Code plugin and passes it via `--plugin-dir`. Other CLI backends use the prompt catalog only. ## Snapshots and refresh OpenClaw snapshots eligible skills **when a session starts** and reuses that list for all subsequent turns in the session. Changes to skills or config take effect on the next new session. Skills refresh mid-session in two cases: - The skills watcher detects a `SKILL.md` change. - A new eligible remote node connects. The refreshed list is picked up on the next agent turn. If the effective agent allowlist changes, OpenClaw refreshes the snapshot to keep visible skills aligned. By default, OpenClaw watches skill folders and bumps the snapshot when `SKILL.md` files change. Configure under `skills.load`: ```json5 { skills: { load: { extraDirs: ["~/Projects/agent-scripts/skills"], allowSymlinkTargets: ["~/Projects/manager/skills"], watch: true, watchDebounceMs: 250, }, }, } ``` Use `allowSymlinkTargets` for intentional symlinked layouts where a skill root symlink points outside the configured root, for example `/skills/manager -> ~/Projects/manager/skills`. If the Gateway runs on Linux but a **macOS node** is connected with `system.run` allowed, OpenClaw can treat macOS-only skills as eligible when the required binaries are present on that node. The agent should run those skills via the `exec` tool with `host=node`. Offline nodes do **not** make remote-only skills visible. If a node stops answering bin probes, OpenClaw clears its cached bin matches. ## Token impact When skills are eligible, OpenClaw injects a compact XML block into the system prompt. The cost is deterministic: ```text total = 195 + Σ (97 + len(name) + len(description) + len(filepath)) ``` - **Base overhead** (only when ≥ 1 skill): ~195 characters - **Per skill:** ~97 characters + your `name`, `description`, and `location` field lengths - XML escaping expands `& < > " '` into entities, adding a few characters per occurrence - At ~4 chars/token, 97 chars ≈ 24 tokens per skill before field lengths Keep descriptions short and descriptive to minimize prompt overhead. ## Related Step-by-step guide to authoring a custom skill.
