skills: Instructions file for Claude Code

CLAUDE.md

skills CLAUDE.md is an instructions file for Claude Code from workersio/skills. It costs 561 tokens per session, scanned A, original, MIT.

Repository instructions for maintaining the Workersio testing workflow and its Claude and Codex plugin files. CLAUDE.md is a guidance file that tells coding agents how a project is organized and maintained.

In plain words
What is it for?
Use it when updating the WIO testing skill, its reference material, plugin manifests, marketplace files, subagents, or test-review reminder hooks.
Why use it?
It keeps important paths, workflow documentation, manifests, hooks, and copied agent files consistent, reducing the chance that maintenance changes the wrong source or omit related configuration.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: reads .claude/ paths; mentions .claude-plugin; mentions CLAUDE.md.

This is workersio/skills's own configuration. It tells Claude Code how to work on skills itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything skills configures →

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

skills CLAUDE.md 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 1mo 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.

CLAUDE.md

This repository packages the wio testing workflow skill and plugin.

Canonical Paths

  • Plugin: plugins/wio
  • Skill source: plugins/wio/skills/wio/SKILL.md
  • References: plugins/wio/skills/wio/references/
  • Hook script: plugins/wio/skills/wio/scripts/test-review-reminder.py
  • Claude plugin manifest: plugins/wio/.claude-plugin/plugin.json
  • Claude marketplace: .claude-plugin/marketplace.json
  • Claude plugin subagents: plugins/wio/agents/
  • Claude project subagents: .claude/agents/ when copied for project-local use
  • Claude hooks: .claude/settings.json
  • Codex plugin manifest: plugins/wio/.codex-plugin/plugin.json
  • Codex marketplace: .agents/plugins/marketplace.json
  • Codex subagents: .codex/agents/
  • Codex hooks: .codex/hooks.json

Maintenance Rules

  • Keep detailed testing content in references, not in SKILL.md.
  • Do not remove existing reference context.
  • Keep plugins/wio/skills/wio as the source of truth for WIO workflow and testing references.
  • Keep the reviewer focused on user value and team time saved.
  • Any test that does not materially reduce user-visible errors, production risk, support load, debugging time, review time, or release risk should be marked REDO or REMOVE.
  • When adding a reference topic, add both overview.md and tools.md, then link it from the WIO reference index.
  • Do not create separate scan, test, workload, review, or doctor skills. They are command modes inside the single wio skill.
  • Do not duplicate references under plugin, cloud, Claude, command, hook, or subagent folders.
  • Subagents may inspect, challenge, and review, but the main agent writes tests and applies the final KEEP, REDO, or REMOVE decision.
  • Claude Code plugins discover Markdown subagents from the plugin root agents/ directory; project-local Claude Code discovers them from .claude/agents/.
  • Codex discovers TOML custom agents from .codex/agents/. Codex plugins do not replace that project custom-agent location.
  • Keep marketplace entries in the official host locations: .agents/plugins/marketplace.json for Codex and .claude-plugin/marketplace.json for Claude Code.
  • Keep install instructions in README.md explicit enough that Codex or Claude can run native marketplace/plugin commands and copy host-specific agent files without a helper script.

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.
