review-behaviors

review-behaviors is a skill for Claude Code from mrinalwadhwa/fluent. It costs 41 tokens per session (340 once invoked), scanned A, original, Apache-2.0.

A review process for statements that describe how software should behave. It checks whether each statement is precise, testable, consistent with the others, and complete enough for its intended scope.

In plain words
What is it for?
Use it to review behavior changes in a code diff, audit all behavior statements in a codebase, and check that they follow recognized event-and-system-response patterns.
Why use it?
Vague or contradictory behavior statements make requirements difficult to implement and verify. The review identifies wording and coverage problems before they cause confusion in development.

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-behaviors 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

Purpose

Decide whether the behavior statements under review are fit to ship. Identify improvements that would make each statement more precise about what the system does, or the collection more coherent and complete as a whole.

Scope

The invoking layer decides what's in scope. For a diff-scoped review, that's the behavior statements changed in the diff. For a full-codebase audit, that's the entire set of behavior statements. Check each statement for quality and check the collection for coherence and completeness.

Method

  1. Read references/behaviors.md for behavior-writing standards.

  2. For each in-scope behavior statement:

    • Verify it uses one of the six EARS patterns from references/behaviors.md. Statements without a recognized trigger (WHEN, WHILE, IF, WHERE) or without "THE SYSTEM SHALL" are hard to verify.
    • Evaluate against the "Properties of a good behavior statement" and "What not to specify" sections in references/behaviors.md.
    • Identify improvements.
  3. Check the collection for coherence — vocabulary consistency, contradictions, coverage, and redundancy — using the "Coherence across behavior statements" section of references/behaviors.md.

  4. For each improvement, decide if it blocks shipping. Statements that leak implementation, combine multiple behaviors, or lack a way to verify typically block. Style issues and minor phrasing don't.

The invoking layer may add checks in addition to those above.

Files

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
