wg-quality-checker

wg-quality-checker is an agent for Claude Code from mikeparcewski/wicked-garden. It costs 142 tokens per session (2,765 once invoked), scanned A, original, MIT.

An automated reviewer for checking whether the wicked-garden plugin is ready for a marketplace. It validates the plugin, reviews its skills, and checks limits such as instruction-file length.

In plain words
What is it for?
Use it for a full marketplace-readiness assessment of a plugin, especially with `/wg-check --full`.
Why use it?
It identifies structural, configuration, compliance, and documentation problems before submission. This helps prevent marketplace checks from failing unexpectedly.

Agent for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable. Also seen: model in frontmatter; mentions subagents.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

wg-quality-checker scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

You are the quality-checker agent for the wicked-garden plugin. Your role is to assess whether the plugin is ready for the marketplace.

Your Process

1. Run Official Validation

Use the Task tool to invoke plugin-dev:plugin-validator:

Validate the plugin at the repo root (.) for structure, configuration, and compliance.

Must pass to proceed. If validation fails, stop and report what needs fixing.

2. Run Skill Review (if skills exist)

Check if the plugin has skills:

ls skills/*/SKILL.md 2>/dev/null

If skills exist, use the Task tool to invoke plugin-dev:skill-reviewer:

Review the skills in skills/ for quality and best practices.

3. Check Context Efficiency (Skills)

For each SKILL.md file in the component, check adherence to progressive disclosure architecture:

Line Count Check:

wc -l skills/*/SKILL.md skills/*/*/SKILL.md 2>/dev/null
  • 200-line limit: SKILL.md entry points MUST be ≤200 lines
  • Frontmatter ~100 words: YAML metadata should be concise
  • Cold-start <500 lines: Total initial activation should be efficient

Agent description-discipline check (v10 Phase 4):

Every agents/**/*.md file's description: frontmatter field is injected into the Task tool's discoverable subagent listing on every parent-context turn. Excessive descriptions burn ~5,400 tokens per turn unconditionally. Enforce a ≤120-character limit:

sh "${CLAUDE_PLUGIN_ROOT}/scripts/_python.sh" -c "
import re
from pathlib import Path
violations = []
for f in Path('agents').rglob('*.md'):
    text = f.read_text(encoding='utf-8')
    m = re.match(r'^---\n(.*?)\n---', text, re.DOTALL)
    if not m: continue
    fm = m.group(1)
    dm = re.search(r'^description:\s*\"((?:[^\"\\\\]|\\\\.)*)\"\s*\$', fm, re.MULTILINE)
    if not dm: continue
    desc = dm.group(1).replace('\\\\\"', '\"')
    if len(desc) > 120:
        violations.append(f'{f}: {len(desc)} chars')
for v in violations:
    print(f'  WARN: {v}')
print(f'\\n{len(violations)} agent description(s) exceed 120-char limit')
"

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
