Skills config

Most skills configuration lives under skills in ~/.openclaw/openclaw.json. Agent-specific visibility lives under agents.defaults.skills and agents.list[].skills.

{
  skills: {
    allowBundled: ["gemini", "peekaboo"],
    load: {
      extraDirs: ["~/Projects/agent-scripts/skills"],
      allowSymlinkTargets: ["~/Projects/manager/skills"],
      watch: true,
      watchDebounceMs: 250,
    },
    install: {
      preferBrew: true,
      nodeManager: "npm",
      allowUploadedArchives: false,
    },
    workshop: {
      autonomous: { enabled: false },
      allowSymlinkTargetWrites: false,
      approvalPolicy: "pending",
      maxPending: 50,
      maxSkillBytes: 40000,
    },
    entries: {
      "image-lab": {
        enabled: true,
        apiKey: { source: "env", provider: "default", id: "GEMINI_API_KEY" },
        env: { GEMINI_API_KEY: "GEMINI_KEY_HERE" },
      },
      peekaboo: { enabled: true },
      sag: { enabled: false },
    },
  },
}

Note

For built-in image generation, use agents.defaults.imageGenerationModel plus the core image_generate tool instead of skills.entries. Skill entries are for custom or third-party skill workflows only.

Loading (skills.load)

Additional skill directories to scan, at the lowest precedence (after bundled and plugin skills). Paths are expanded with `~` support. Trusted real target directories that symlinked skill folders may resolve into, even when the symlink lives outside the configured root. Use this for intentional sibling-repo layouts such as `/skills/manager -> ~/Projects/manager/skills`. Keep this list narrow — do not point at broad roots like `~` or `~/Projects`. Watch skill folders and refresh the skills snapshot when `SKILL.md` files change. Covers nested files under grouped skill roots. Debounce window for skill watcher events in milliseconds.

Install (skills.install)

Prefer Homebrew installers when `brew` is available. Node package manager preference for skill installs. This only affects skill installs — the Gateway runtime should still use Node (Bun is not recommended for WhatsApp/Telegram). Use `openclaw setup --node-manager` for npm, pnpm, or bun; set `"yarn"` manually for Yarn-backed skill installs. Allow trusted `operator.admin` Gateway clients to install private zip archives staged through `skills.upload.*`. Normal ClawHub installs do not need this setting.

Operator Install Policy (security.installPolicy)

Use security.installPolicy when operators need a trusted local command to approve or block skill and plugin installs with host-specific policy. The policy runs after OpenClaw has staged source material and before the install or update continues. It applies to ClawHub skills, uploaded skills, Git/local skills, skill dependency installers, and plugin install/update sources.

{
  security: {
    installPolicy: {
      enabled: true,
      // Omit targets to cover every supported target.
      targets: ["skill", "plugin"],
      exec: {
        source: "exec",
        command: "/usr/local/bin/openclaw-install-policy",
        args: ["--json"],
        timeoutMs: 10000,
        noOutputTimeoutMs: 10000,
        maxOutputBytes: 1048576,
        passEnv: ["OPENCLAW_STATE_DIR", "PATH"],
        env: { POLICY_MODE: "strict" },
        trustedDirs: ["/usr/local/bin"],
      },
    },
  },
}

Enables operator-owned install policy. When enabled without a valid `exec` command, installs fail closed. Optional target filter. When omitted, policy applies to every supported target so new installs do not unexpectedly fail open. Absolute path to the trusted policy executable. OpenClaw runs it without a shell and validates the path before use. Static arguments passed after `command`. Maximum wall-clock runtime for one policy decision. Maximum time without stdout or stderr output before the policy fails closed. Maximum combined stdout and stderr bytes accepted from the policy process. Literal environment variables provided to the policy process. Environment variable names copied from the OpenClaw process into the policy process. Only named variables are passed. Optional allowlist of directories that may contain the policy executable. Bypasses command path ownership and permission checks. Use only when the path is protected by another mechanism. Allows the configured command path to be a symlink. The resolved target must still satisfy the other path checks. Interpreter script arguments must be direct regular files, not symlinks.

The policy receives one JSON object on stdin with protocolVersion: 1, openclawVersion, targetType, targetName, sourcePath, sourcePathKind, optional structured source, structured origin, and request. It must write one JSON object on stdout: { "protocolVersion": 1, "decision": "allow" } or { "protocolVersion": 1, "decision": "block", "reason": "..." }. Non-zero exit, timeout, malformed JSON, missing fields, or unsupported protocol versions fail closed.

OpenClaw does not execute install policy during normal Gateway startup. Installs and updates fail closed when policy is enabled but unavailable. openclaw doctor performs static validation, and openclaw doctor --deep executes a synthetic install probe against the configured command.

Bulk updates apply policy per target: a blocked skill or plugin update fails that target without disabling the policy or skipping later targets in the batch.

Example stdin:

{
  "protocolVersion": 1,
  "openclawVersion": "2026.6.1",
  "targetType": "skill",
  "targetName": "weather",
  "sourcePath": "/var/folders/.../openclaw-skill-clawhub/root",
  "sourcePathKind": "directory",
  "source": {
    "kind": "clawhub",
    "authority": "openclaw",
    "mutable": false,
    "network": true
  },
  "origin": {
    "type": "clawhub",
    "registry": "https://clawhub.openclaw.ai",
    "slug": "weather",
    "version": "1.0.0"
  },
  "request": {
    "kind": "skill-install",
    "mode": "install",
    "requestedSpecifier": "clawhub:[email protected]"
  },
  "skill": {
    "installId": "clawhub"
  }
}

Minimal policy command:

#!/usr/bin/env node

let input = "";
process.stdin.setEncoding("utf8");
process.stdin.on("data", (chunk) => {
  input += chunk;
});
process.stdin.on("end", () => {
  const request = JSON.parse(input);
  if (request.targetType === "plugin" && request.source?.kind === "local-path") {
    process.stdout.write(
      JSON.stringify({
        protocolVersion: 1,
        decision: "block",
        reason: "local plugin paths are not approved on this host",
      }),
    );
    return;
  }
  process.stdout.write(JSON.stringify({ protocolVersion: 1, decision: "allow" }));
});

Bundled skill allowlist

Optional allowlist for **bundled** skills only. When set, only bundled skills in the list are eligible. Managed, agent-level, and workspace skills are unaffected.

Per-skill entries (skills.entries)

Keys under entries match the skill name by default. If a skill defines metadata.openclaw.skillKey, use that key instead. Quote hyphenated names (JSON5 allows quoted keys).

`false` disables the skill even when bundled or installed. The `coding-agent` bundled skill is opt-in — set it to `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: `{ source: "env", provider: "default", id: "VAR_NAME" }`. 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.

Agent allowlists (agents)

Use agent config when you want the same machine/workspace skill roots but a different visible skill set per agent.

{
  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
    ],
  },
}

Shared baseline allowlist inherited by agents that omit `agents.list[].skills`. Omit entirely to leave skills unrestricted by default. Explicit final skill set for that agent. Explicit lists **replace** inherited defaults — they do not merge. Set to `[]` to expose no skills for that agent.

Warning

Agent skill allowlists are a visibility and loading filter for OpenClaw skill discovery, prompts, slash-command discovery, sandbox sync, and skill snapshots. They are not a shell-time authorization boundary. If an agent can run host exec, that shell can still run external clients or read host files that are visible to the execution user, including MCP client registries such as ~/.openclaw/skills/config/mcporter.json. For per-agent MCP isolation, combine skill allowlists with sandbox/OS-user isolation, deny or tightly allowlist host exec, and prefer per-agent credentials at the MCP server.

Workshop (skills.workshop)

When `true`, agents can create pending proposals from durable conversation signals after successful turns. User-prompted skill creation always goes through Skill Workshop regardless of this setting. `pending` requires operator approval before agent-initiated apply, reject, or quarantine. `auto` allows those actions without approval. Allow Skill Workshop apply to write through workspace skill symlinks whose real target is already trusted by `skills.load.allowSymlinkTargets`. Keep this disabled unless generated proposal applies should mutate that shared skill root. Maximum pending and quarantined proposals retained per workspace. Maximum proposal body size in bytes. Proposal descriptions are hard-capped at 160 bytes because they appear in discovery and listing output.

Symlinked skill roots

By default, workspace, project-agent, extra-dir, and bundled skill roots are containment boundaries. A symlinked skill folder under <workspace>/skills that resolves outside the root is skipped with a log message.

To allow an intentional symlink layout, declare the trusted target:

{
  skills: {
    load: {
      extraDirs: ["~/Projects/manager/skills"],
      allowSymlinkTargets: ["~/Projects/manager/skills"],
    },
  },
}

With this config, <workspace>/skills/manager -> ~/Projects/manager/skills is accepted after realpath resolution. extraDirs scans the sibling repo directly; allowSymlinkTargets preserves the symlinked path for existing layouts.

Skill Workshop apply does not write through those symlinks by default. To let Workshop apply mutate skills under already-trusted symlink targets, opt in separately:

{
  skills: {
    load: {
      allowSymlinkTargets: ["~/Projects/manager/skills"],
    },
    workshop: {
      allowSymlinkTargetWrites: true,
    },
  },
}

Managed ~/.openclaw/skills and personal ~/.agents/skills directories already accept skill-directory symlinks (per-skill SKILL.md containment still applies).

Sandboxed skills and env vars

Warning

`skills.entries.

.envandapiKeyapply to **host** runs only. Inside a sandbox they have no effect — a skill that depends onGEMINI_API_KEYwill fail withapiKey not configured` unless the sandbox is given the variable separately.

Pass secrets into a Docker sandbox with:

{
  agents: {
    defaults: {
      sandbox: {
        docker: {
          env: { GEMINI_API_KEY: "your-key-here" },
        },
      },
    },
  },
}

Note

Users with Docker daemon access can inspect sandbox.docker.env values through Docker metadata. Use a mounted secret file, a custom image, or another delivery path when that exposure is not acceptable.

Loading order reminder

workspace/skills      (highest)
workspace/.agents/skills
~/.agents/skills
~/.openclaw/skills
bundled skills
skills.load.extraDirs (lowest)

Changes to skills and config take effect on the next new session when the watcher is enabled, or on the next agent turn when the watcher detects a change.
