metalworks: Skill for Claude Code

.claude/skills/pr-ready/SKILL.md

pr-ready is a skill for Claude Code from Lab2A/metalworks. It costs 134 tokens per session (1,077 once invoked), scanned A, original, MIT.

A pre-pull-request checklist for the metalworks codebase. A pull request is a proposed set of code changes submitted for review before merging them into a shared project.

In plain words
What is it for?
Use it to run the project's automated quality checks and inspect items such as interface consistency across the command line, MCP, facade, and skill surfaces.
Why use it?
It finds code, type, test, formatting, generated-file, documentation, and change-log problems before review, including checks that continuous integration may omit.

Skill for Claude Code

Written for Claude Code: installed under .claude/. Also seen: mentions .claude-plugin.

This is Lab2A/metalworks's own configuration. It tells Claude Code how to work on metalworks 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 metalworks configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is uv run python scripts/gen_ts_types.py --check.

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

pr-ready 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 2mo 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.

/pr-ready — pre-PR readiness check

You are checking whether the current branch is ready to open a PR against metalworks. Run the automatable gates, inspect the diff for what CI can't check, and report a clean ✓ / ✗ / ? checklist with what's left. metalworks is contract-first with four-surface parity (see docs/architecture.md) — that's what most of these checks protect, so name the principle when something's off.

First, see what changed:

git fetch origin main -q
git diff --stat origin/main...HEAD    # committed changes; add `git status -s` for uncommitted

1. The gate — run each, report pass/fail with the failing output

uv run ruff check .
uv run ruff format --check .
uv run pyright
uv run pytest -q

These are exactly what CI runs (matrix py3.11–3.13 × bare/all; you're running one interpreter, which is enough to catch real failures). A failure here blocks the PR — show the output and the fix.

2. Contract drift — the gate CI does NOT run

uv run python scripts/gen_ts_types.py --check

If it reports drift, the committed ts/contract.ts or src/metalworks/contract/schema/*.json are stale. Run uv run python scripts/gen_ts_types.py and tell the contributor to commit the regenerated files. This is the one gate CI misses, so it's the most common silent break.

3. Surface parity — inspect the diff (judgment, not a command)

If the diff adds or changes a primitive (a research verb / a user-facing capability), confirm it moved on all four surfaces and flag any missing one:

  • Facade — a method on Metalworks in src/metalworks/client.py.
  • CLI — a @research_app.command(...) in src/metalworks/cli/__init__.py (+ a _print_* renderer).
  • MCP — a body in src/metalworks/mcp/tools.py, an async wrapper in src/metalworks/mcp/server.py, and an entry in that file's _TOOL_WRAPPERS tuple (forgetting the tuple = the tool isn't registered).
  • Skill — a plugin/skills/<name>/SKILL.md.

A new contract model also means: it's in scripts/gen_ts_types.py MODELS (+ _SCHEMAS if a snapshot root) and exported from src/metalworks/contract/__init__.py + __all__. Removing a surface is the same rule in reverse — all four gone, plus every doc reference.

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.
