dev:validate

SkillDev tools

Use when the user wants to validate the plugin, check integrity, verify cross-references, or before a release. Also use when the user says 'validate', 'check plugin', or 'verify'.

Available today. Use it from your connected AI after setup.

Connect ahel once, and every AI you use reads what you have installed.

Then ask your AI: use the dev:validate skill

What this skill tells your AI

The instructions your AI receives, as published by raphaelchristi/harness-evolver in .claude/skills/dev-validate/SKILL.md and read by ahel’s review.

Check plugin integrity: skill/agent frontmatter, cross-references, Python tool syntax, version sync, hook script executability.

Checks

1. Version Sync

PKG_V=$(python3 -c "import json; print(json.load(open('package.json'))['version'])")
PLUGIN_V=$(python3 -c "import json; print(json.load(open('.claude-plugin/plugin.json'))['version'])")
if [ "$PKG_V" = "$PLUGIN_V" ]; then
    echo "OK: versions match ($PKG_V)"
else
    echo "FAIL: package.json=$PKG_V, plugin.json=$PLUGIN_V"
fi

2. Skill Frontmatter

For each skills/*/SKILL.md:

  • Must have name: in frontmatter
  • Must have description: in frontmatter
  • Must have allowed-tools: in frontmatter
for f in skills/*/SKILL.md; do
    NAME=$(grep -m1 "^name:" "$f" | cut -d: -f2- | xargs)
    DESC=$(grep -m1 "^description:" "$f")
    TOOLS=$(grep -m1 "^allowed-tools:" "$f")
    if [ -z "$NAME" ] || [ -z "$DESC" ] || [ -z "$TOOLS" ]; then
        echo "FAIL: $f missing frontmatter fields"
    else
        echo "OK: $f ($NAME)"
    fi
done

3. Agent Frontmatter

For each agents/*.md:

  • Must have name: in frontmatter
  • Must have description: in frontmatter
  • Must have tools: in frontmatter
  • Must have color: in frontmatter
for f in agents/*.md; do
    NAME=$(grep -m1 "^name:" "$f" | cut -d: -f2- | xargs)
    COLOR=$(grep -m1 "^color:" "$f" | cut -d: -f2- | xargs)
    if [ -z "$NAME" ] || [ -z "$COLOR" ]; then
        echo "FAIL: $f missing name or color"
    else
        echo "OK: $f ($NAME, $COLOR)"
    fi
done

4. Agent Cross-References

Check that every subagent_type: referenced in skills exists as an agent file:

for AGENT in $(grep -roh 'subagent_type: "[^"]*"' skills/ | sed 's/subagent_type: "//;s/"//' | sort -u); do
    if [ ! -f "agents/$AGENT.md" ]; then
        echo "FAIL: subagent_type '$AGENT' referenced in skills but agents/$AGENT.md not found"
    else
        echo "OK: $AGENT agent exists"
    fi
done

5. Python Tool Syntax

ERRORS=0
for f in tools/*.py; do
    python3 -c "import ast; ast.parse(open('$f').read())" 2>&1
    if [ $? -ne 0 ]; then
        echo "FAIL: $f has syntax errors"
        ERRORS=$((ERRORS+1))
    else
        echo "OK: $f"
    fi
done
echo "Python tools: $ERRORS errors"

6. Hook Script

if [ -f "hooks/session-start.sh" ]; then
    if [ -x "hooks/session-start.sh" ]; then
        echo "OK: hooks/session-start.sh is executable"
    else
        echo "FAIL: hooks/session-start.sh not executable"
    fi
    if [ -f "hooks/hooks.json" ]; then
        python3 -c "import json; json.load(open('hooks/hooks.json'))" 2>&1
        if [ $? -eq 0 ]; then echo "OK: hooks.json valid JSON"; else echo "FAIL: hooks.json invalid"; fi
    fi
else
    echo "WARN: no hooks/session-start.sh"
fi

7. CLAUDE.md Accuracy

Check that tool count and agent count in CLAUDE.md match reality:

TOOL_COUNT=$(ls tools/*.py 2>/dev/null | wc -l)
AGENT_COUNT=$(ls agents/*.md 2>/dev/null | wc -l)
echo "Tools: $TOOL_COUNT Python files"
echo "Agents: $AGENT_COUNT agent definitions"
