review-prompt

review-prompt is a skill for Claude Code from doodledood/manifest-dev. It costs 60 tokens per session (530 once invoked), scanned A, original, MIT.

A review guide for checking the quality of instructions written for language models, without changing those instructions.

In plain words
What is it for?
It helps assess a prompt, explain its strengths and problems, rank the most important fix, and suggest a concrete improvement.
Why use it?
It helps find contradictions, unnecessary wording, missing goals, and other issues that can make an agent behave incorrectly.

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

review-prompt 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 10d 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.

What it actually says

Review LLM prompts. Report findings without modifying files — this skill diagnoses; it never edits the prompt.

First: invoke the prompt-engineering skill to load the principles. Evaluate the prompt against them.

The provenance question leads: for each line, where did it come from — a user ruling, knowledge outside what the run will read, or a default it counteracts? A line the author could have worked out from material the run also gets is the finding. Judge a prompt by what its lines do, never by sections it lacks: a short prompt with nothing spare is the target, not a deficient one.

Input: if no prompt is given (file path or inline text), ask before analyzing — don't assume.

Report format:

Assessment: {Excellent | Good with Minor Issues | Needs Work}

Strengths — what's working, what the author should preserve.

Issues:

Issue Severity Fix
{description} High / Medium / Low {concrete recommendation}

Priority: the highest-impact change first.

Severity:

  • High — the prompt actively misbehaves or breaks a contract. Examples: contradiction between two rules that can't both hold; missing the goal entirely; absolute used on a judgment call that observably misfires; the agent declares a need for a tool it doesn't have, or omits a tool it actually uses.
  • Medium — the prompt works but drifts toward known failure modes. Examples: vague directive that produces inconsistent behavior across runs; restated model default adding noise the model has to wade through; a line whose only provenance is the author's own reading; a real gap left unclosed; arbitrary numbers without a rubric; boundary failures — naming a harness-bound primitive, a rule-scope qualifier that silently excludes valid cases, mechanism stated as the only path, or one principle split across multiple places.
  • Low — minor friction with no functional impact. Examples: duplication that doesn't change behavior; awkward phrasing where the meaning is still unambiguous; stylistic-only cleanup.

Only flag high-confidence issues. Low-confidence findings are noise — skip style preferences, minor wording, and unverified hunches.

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.
