+# Skills Config
+
+All skills-related configuration lives under `skills` in `~/.clawdbot/clawdbot.json`.
+
+```json5
+{
+  skills: {
+    allowBundled: ["brave-search", "gemini"],
+    load: {
+      extraDirs: [
+        "~/Projects/agent-scripts/skills",
+        "~/Projects/oss/some-skill-pack/skills"
+      ]
+    },
+    install: {
+      preferBrew: true,
+      nodeManager: "npm" // npm | pnpm | yarn | bun
+    },
+    entries: {
+      "nano-banana-pro": {
+        enabled: true,
+        apiKey: "GEMINI_KEY_HERE",
+        env: {
+          GEMINI_API_KEY: "GEMINI_KEY_HERE"
+        }
+      },
+      peekaboo: { enabled: true },
+      sag: { enabled: false }
+    }
+  }
+}
+```
+
+## Fields
+
+- `allowBundled`: optional allowlist for **bundled** skills only. When set, only
+  bundled skills in the list are eligible (managed/workspace skills unaffected).
+- `load.extraDirs`: additional skill directories to scan (lowest precedence).
+- `install.preferBrew`: prefer brew installers when available (default: true).
+- `install.nodeManager`: node installer preference (`npm` | `pnpm` | `yarn` | `bun`, default: npm).
+- `entries.<skillKey>`: per-skill overrides.
+
+Per-skill fields:
+- `enabled`: set `false` to disable a skill even if it’s bundled/installed.
+- `env`: environment variables injected for the agent run (only if not already set).
+- `apiKey`: optional convenience for skills that declare a primary env var.
+
+## Notes
+
+- Keys under `entries` map to the skill name by default. If a skill defines
+  `metadata.clawdbot.skillKey`, use that key instead.
+- Changes to skills are picked up on the next new session.
