 ### !pause / !resume <agent>
 Temporarily mute an agent without destroying it. Agent stays alive but stops responding. Useful when you need a channel to yourself.

+### SKILL.md pattern for agent tools
+Replace hardcoded tools in agent.py with a discoverable skill directory. Each skill is a folder with a SKILL.md (description, parameters, examples) and a script (run.sh/run.py).
+
+```
+~/.fireclaw/skills/
+  web_search/
+    SKILL.md        # name, description, parameters — parsed into tool definition
+    run.py          # actual implementation
+  fetch_url/
+    SKILL.md
+    run.py
+  git_diff/
+    SKILL.md
+    run.sh
+```
+
+Agent discovers skills at boot, loads SKILL.md into Ollama tool definitions, invokes scripts on tool call. Adding a new tool = drop a folder. No agent.py changes needed.
+
+Could also support per-template skill selection — coder gets git/code skills, researcher gets search/fetch skills, worker gets everything.
