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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00066 | $0.03870 |
| Opus 5 | $0.00033 | $0.01935 |
| Sonnet 5 | $0.00013 | $0.00774 |
| Haiku 4.5 | $0.00007 | $0.00387 |
Grade C, and why
ship-check (clarifyprompt-mcp overrides) scanned grade C with 1 finding 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 12d 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.
Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
The single most expensive class of mistake this repo has hit: a `package-lock.json` regeneration that silently changed more than intended. When a release touches the lockfile (dependency bump, SDK upgrade, `npm audit fix How it starts
The opening of the file, as written. The whole thing — 216 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ship-check — clarifyprompt-mcp overrides
Loaded by the user-scoped ship-check skill at ~/.claude/skills/ship-check/SKILL.md when running audits in this repo. Uses the cascade syntax (CSS-like specificity) the parent skill defines:
OVERRIDE: <general-check>— replace the general check entirelyDISABLE: <general-check>— skip the general check, requires a rationaleAUGMENT: <general-check>— keep general + add moreADD: <new-check>— a check with no general equivalent
Each directive is also tagged with a generalization hint — whether the check is purely repo-specific forever, or a candidate to promote back to the user-scoped skill once it proves useful elsewhere.
AUGMENT: Version consistency — extra source for MCP Node SDK
The general check already inspects package.json, package-lock.json, server.json (both top-level and packages[*].version), CHANGELOG.md, and ecosystem-specific manifests. This repo additionally has:
src/index.ts→ theMcpServer({ name, version })literal must match all of the above.
Run the general check, then verify grep -oE 'version: "[^"]+"' src/index.ts matches package.json#version.
Generalization hint: the src/index.ts McpServer literal is specific to MCP servers built with @modelcontextprotocol/sdk for Node. Promotion candidate once a second such project adopts ship-check, with detection gated on the SDK being a declared dep.
AUGMENT: Secrets sweep — repo-specific guards
Keep all general patterns AND additionally hard-fail on:
- Any 40+ character hex string following
_authToken=(a leaked~/.npmrcvalue). - The literal token prefix
npm_EYF3iBwowe rotated during 1.2.0 prep — defense against someone re-adding it from transcript history.
The second pattern is an artifact of this project's history and expires once the token is safely out of all backscroll. Review quarterly; remove when no longer needed.
Generalization hint: "add project-specific secret patterns" is itself a general capability — the parent skill already supports it via this AUGMENT operator. The specific patterns here are clarifyprompt-only.
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.

ship-check (clarifyprompt-mcp overrides) is a skill published in the GitHub repository LumabyteCo/clarifyprompt-mcp (12 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 66 tokens to every session and 3,870 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
