SolidworksMCP-python: Skill for Claude Code

.claude/skills/openspec-proposal-auditor/SKILL.md

openspec-proposal-auditor is a skill for Claude Code from andrewbartels1/SolidworksMCP-python. It costs 103 tokens per session (2,856 once invoked), scanned A, original, MIT.

A review process for checking OpenSpec planning documents against the actual codebase and linked GitHub issues. OpenSpec is a format for describing proposed software changes before they are built.

In plain words
What is it for?
It is for auditing proposals, specifications, designs, and task lists for accuracy and readiness.
Why use it?
It catches unclear scope, stale statements, and claims that do not match the repository before implementation starts.

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

openspec-proposal-auditor 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 222 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Role: OpenSpec Proposal Auditor

Audit the planning artifacts of an OpenSpec change for clarity, conciseness, scope discipline, and — critically — factual accuracy against ground truth: the actual repo (code, tests, docs) and the actual state of any GitHub issues/PRs the artifacts reference. This is a read-only review. It never edits change artifacts; it produces findings and a concern register for the user (or /opsx:update) to act on.

Gate, not a formality. The point of this skill is to catch stale or invented claims before design.md/tasks.md get treated as ready to implement — this repo has a documented history of exactly that problem (see openspec/changes/close-tool-surface-gaps-and-housekeeping/proposal.md for a real example: three issues turned out to be already partly shipped by merged PRs the issue text didn't know about). A proposal that "reads well" is not the bar. A proposal whose every checkable claim has been checked, is.

When to run this

  • Before running /opsx:apply on a change — always, not just on request.
  • Immediately after any /opsx:update revision to the same change.
  • On explicit request ("audit this proposal", "check the proposal for issue #NN", "run the proposal auditor").

Selecting the change

If a change name is given, use it. Otherwise run openspec list --json, and if more than one change exists, list the 3-4 most recently modified and ask the user to pick (same convention as /opsx:update). Announce "Auditing change: ".

Procedure

Work through the steps in order. Do not skip Step 1 to jump to scoring — the scoring in Step 2 depends on the verification table Step 1 produces, and the Concern Register in Step 3 depends on both.

Step 0 — Load everything

  • openspec status --change "<name>" --json for artifact paths and state.
  • Read every existing artifact in full: proposal.md, every specs/**/*.md, design.md, tasks.md. Read from disk, not from conversation memory, even if you authored them earlier this session.
  • Read openspec/config.yaml (or openspec/project.md if this store uses that filename) for the project's own stated context and conventions — this is the baseline Step 2's Drift check compares against.
  • Read CLAUDE.md at the repo root for architecture/convention ground truth not captured in the openspec config.

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.
