Claw Doctor — OpenClaw Self-Repair Skill

This skill diagnoses and fixes common OpenClaw / NanoClaw problems. When something breaks, run through the checklist below before giving up.

When to Activate

Activate this skill when the user reports any of the following:

• "skill not found" / skill does not trigger
• "No such file or directory" when running a skill script
• API key errors from a skill
• Skill produces no output or wrong output
• "SKILL.md is invalid" / YAML parse errors
• A skill works globally but not in workspace (or vice versa)
• Skills were working before but stopped after an update

Skill Load Order & Paths

OpenClaw loads skills from two locations. Workspace skills take priority.

Priority 1 (high): <workspace>/skills/<skill-name>/SKILL.md
Priority 2 (low):  ~/.openclaw/skills/<skill-name>/SKILL.md

Diagnostic: list all loaded skills

# Show what's installed globally
ls ~/.openclaw/skills/ 2>/dev/null || echo "No global skills dir"

# Show what's installed in current workspace
ls ./skills/ 2>/dev/null || echo "No workspace skills dir"

If a skill appears in both, the workspace version wins — check for version mismatches.

Problem 1 — Skill Does Not Trigger

Symptom: User invokes a skill but Claude ignores it or does not follow the skill procedure.

Diagnosis checklist:

1. Is the SKILL.md actually present and readable?

   cat ./skills/<skill-name>/SKILL.md | head -20
   

2. Does the frontmatter YAML parse correctly?

   python3 -c "
   import re, sys
   txt = open('skills/<skill-name>/SKILL.md').read()
   fm = re.search(r'^---\n(.*?)\n---', txt, re.DOTALL)
   print('Frontmatter found:', bool(fm))
   if fm:
       import yaml; d = yaml.safe_load(fm.group(1)); print('Keys:', list(d.keys()))
   "
   

3. Do the keywords in the SKILL.md match what the user said?

   • Add more keyword variants (synonyms, abbreviations) if not matching.

4. Is description clear enough for the model to identify the skill?

   • Short, specific descriptions outperform vague ones.

Fix: Ensure frontmatter is valid YAML (no tabs, proper quoting, correct indentation).

Problem 2 — Script Not Found (Path Resolution)

Symptom: bash: scripts/run: No such file or directory

This is the most common skill bug. Scripts referenced in SKILL.md as scripts/foo are relative to the skill's installation directory inside the OpenClaw plugin cache, not the current working directory.

Canonical fix — resolve the script path dynamically before every use:

# For a skill named "my-skill" with a script named "run"
MY_SCRIPT=$(find ~/.openclaw -name "run" -path "*/my-skill/*/scripts/*" -type f 2>/dev/null | head -1)
# Fallback: check workspace skills
[ -z "$MY_SCRIPT" ] && MY_SCRIPT=$(find ./skills -name "run" -path "*/my-skill/scripts/*" -type f 2>/dev/null | head -1)

if [ -z "$MY_SCRIPT" ]; then
  echo "ERROR: script not found. Is the skill installed?"
  exit 1
fi

$MY_SCRIPT <args>

Also check: Is the script executable?

chmod +x ~/.openclaw/skills/my-skill/scripts/*
chmod +x ./skills/my-skill/scripts/*

Problem 3 — API Key Not Configured

Symptom: Skill returns {"success": false, "setup_required": true} or 401/403 errors.

Standard API key setup flow:

1. The skill's SKILL.md should document where the key is stored (usually ~/.openclaw/secrets/<skill-name>.key or an env var).
2. Check if the key file exists:

   ls ~/.openclaw/secrets/ 2>/dev/null || echo "No secrets dir"
   

3. Run the skill's setup command (usually scripts/run setup <api-key>).
4. Verify the key was saved:

   cat ~/.openclaw/secrets/<skill-name>.key 2>/dev/null | head -c 20
   

If no setup command exists, ask the user to set the env var directly:

export SKILL_API_KEY="their-key-here"
# Add to ~/.zshrc or ~/.bashrc for persistence

Problem 4 — Dependency Missing (Node.js / Python / tool)

Symptom: node: command not found, python3: No such file or directory, jq: command not found

Quick dependency check:

echo "=== Core deps ===" && \
node --version 2>/dev/null || echo "MISSING: node" && \
python3 --version 2>/dev/null || echo "MISSING: python3" && \
jq --version 2>/dev/null || echo "MISSING: jq" && \
curl --version 2>/dev/null | head -1 || echo "MISSING: curl"

Fix by platform:

For Python skill dependencies:

pip3 install -r skills/<skill-name>/requirements.txt 2>/dev/null \
  || echo "No requirements.txt found"

For Node skill dependencies:

cd skills/<skill-name> && npm install 2>/dev/null \
  || echo "No package.json found"

Problem 5 — YAML Frontmatter Errors

Symptom: Skill loads but metadata is wrong / keywords not indexed.

Valid frontmatter template:

---
name: my-skill-name         # lowercase, hyphens only
description: One clear sentence describing what this skill does.
keywords:
  - keyword-one
  - keyword-two
license: MIT
---

Common mistakes:

Validate:

python3 -c "
import yaml, sys
txt = open('skills/<skill-name>/SKILL.md').read().split('---')[1]
try:
    d = yaml.safe_load(txt)
    print('OK:', d)
except yaml.YAMLError as e:
    print('YAML ERROR:', e)
    sys.exit(1)
"

Problem 6 — Skill Worked Before, Broke After Update

Symptom: OpenClaw updated and a skill stopped working.

Checklist:

1. Check if the OpenClaw plugin cache was cleared:

   ls ~/.openclaw/plugins/cache/ 2>/dev/null | head -10
   

2. Reinstall the skill from source:

   # From a cloned skills repo
   cp -r /path/to/skills-repo/skills/<skill-name> ~/.openclaw/skills/
   

3. Check for breaking changes in OpenClaw's skill API — look at the OpenClaw changelog for SKILL.md format updates.

4. Test the script directly (bypassing OpenClaw):

   bash skills/<skill-name>/scripts/<main-script> --help
   

Full Health Check

Run this to get a complete snapshot of the OpenClaw environment:

echo "=== OpenClaw Health Check ===" && \
echo "--- Global skills ---" && ls ~/.openclaw/skills/ 2>/dev/null || echo "(none)" && \
echo "--- Workspace skills ---" && ls ./skills/ 2>/dev/null || echo "(none)" && \
echo "--- Secrets ---" && ls ~/.openclaw/secrets/ 2>/dev/null || echo "(none)" && \
echo "--- Plugin cache ---" && ls ~/.openclaw/plugins/cache/ 2>/dev/null | head -5 || echo "(empty)" && \
echo "--- Dependencies ---" && \
  node --version 2>/dev/null && \
  python3 --version 2>/dev/null && \
  jq --version 2>/dev/null && \
echo "=== Done ==="

For Claude Code Users

This skill also works as a Claude Code user-invocable skill. Add the following to ~/.claude/CLAUDE.md under ## User-Invocable Skills:

### claw-doctor

Diagnose and fix OpenClaw / NanoClaw problems.

**Trigger**: user mentions skill not loading, script not found, API key error, SKILL.md broken, OpenClaw not working

**Procedure**: Follow the claw-doctor SKILL.md checklist:
1. Identify symptom category (trigger / script path / API key / dependency / YAML / post-update)
2. Run the relevant diagnostic commands
3. Apply the fix and verify with the Full Health Check

1. The symptom (exact error message or behavior)
2. Root cause
3. Diagnostic command
4. Fix

Keep entries short and command-first. The doctor should be fast to consult.
