vale-ai-tells: Skill for Claude Code

.claude/skills/codex-review-prose-fix/SKILL.md

codex-review-prose-fix is a skill for Claude Code from tbhb/vale-ai-tells. It costs 62 tokens per session (328 once invoked), scanned A, original, MIT.

A read-only review step for checking a prose-editing fix. It looks for changed meaning, missing precision, unrelated edits, suppression comments, and language problems.

In plain words
What is it for?
Use it after a prose linter has passed and a writer has edited a target file. It checks the full change and reports either that it is clean or the exact corrections still needed.
Why use it?
A spelling or style checker may miss changes that alter the original claim or make the writing less precise. This review provides an independent check before the fix is accepted.

Skill for Claude Code

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

This is tbhb/vale-ai-tells's own configuration. It tells Claude Code how to work on vale-ai-tells 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 vale-ai-tells configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is bash .agents/skills/codex-fix-prose/scripts/check-suppressions.sh --diff <state> <target>.

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

codex-review-prose-fix 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 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.

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 a prose fix

The caller supplies the repository root, target, and workflow state. Work read-only. Run:

bash .agents/skills/codex-fix-prose/scripts/check-suppressions.sh --diff <state> <target>
bash .agents/skills/codex-fix-prose/scripts/check-suppressions.sh --verify <state> <target>

Read the resulting target in full. Don't repeat the prose lint command. Its clean result is the premise of this review.

Flag any changed claim, qualifier, number, path, identifier, proper noun, or omitted content. Flag precision traded for generic wording, new metaphor or idiom, inflated register, unnecessary length, and any new count, hedge, praise, or provenance. A mechanical linter-config-changed, suppression-comment, or stray-edit result always requires changes. Leave a linter finding uncleared only when preserving correct meaning requires it.

Sweep the whole diff for every class of issue you find, then return exactly:

REVIEW: CLEAN

or:

REVIEW: CHANGES REQUIRED

1. `<exact text>` — <problem>. Fix: <specific correction>.

Don't edit any file.

Files

What ships with it

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.
