prompting:scan

prompting:scan is a skill for Claude Code from bendrucker/claude. It costs 62 tokens per session (1,712 once invoked), scanned A, original, MIT.

A repository-prose scanner that detects common AI-writing patterns in files such as READMEs, documentation, proposals, and skill files.

In plain words
What is it for?
Use it to audit selected prose files, measure trope density in a draft, compare two drafts, and report each finding with its file location.
Why use it?
It helps find repetitive or unnatural wording before it is committed or checked in continuous integration, a system that automatically validates changes.

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

prompting:scan 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 5d ago.

The scan reads SKILL.md. This mod also ships 11 executable files (scripts/audit.test.ts, scripts/audit.ts, scripts/edit.ts, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Scan

Run the scanner over the paths in $ARGUMENTS, defaulting to the current directory:

bun ${CLAUDE_SKILL_DIR}/scripts/scan.ts [<path>...] [--all] [--quiet] [--score]

It reports each alert as file:line:col: level: check: message on stdout and a per-check count table on stderr, and exits non-zero on any alert. A check is an error once the precision eval confirms it and a warning until then. --quiet drops the table. --score replaces it with one row per scanned file, clean files included, giving its alerts, its prose words outside frontmatter and code, and alerts per 1,000 words, plus a total. Run it before and after an edit round over the same paths to compare them.

Without --all it reads the paths that hold documents a model executes: SKILL.md, CLAUDE.md, AGENTS.md, .claude/agents, .claude/commands, .claude/rules, a skill's references/, and a prompt/ or prompts/ directory holding .md or .txt files. Use --all for a prompt that lives somewhere else, such as one extracted from a string in a product repo. It reads .md and .txt under either setting, so --all widens which documents count without pulling in source files. Either way it also scans the files a scanned CLAUDE.md or AGENTS.md imports with @path, up to four hops deep, and lists on stderr each import outside the scanned paths or missing. It skips node_modules, .git, fixtures, __snapshots__, and evals.

Checks

Rewrites

Sharpen the sentence the alert names.

  • Prompting.WeakModality: the instruction is a suggestion the model can decline, so whether it fires is left to the run.
  • Prompting.VagueCriterion: the done-state is one the model cannot check. The model decides for itself when to stop.
Deletions

Delete the span the alert names.

  • Prompting.NoOp: the instruction restates a default the model already follows, spending context and changing nothing.
  • Prompting.StaleMeasurement: the document reports a tally a past run counted. The run prints the number again, so the document caches its own output and drifts as the work behind it moves.
  • Prompting.TicketRef: a bare issue number points at a tracker the model cannot read, and the prose around it goes stale when the issue closes.

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.
