Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00062 | $0.01712 |
| Opus 5.5 | $0.00025 | $0.00685 |
| Sonnet 5.5 | $0.00012 | $0.00342 |
| Haiku 4.5 | $0.00006 | $0.00171 |
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.
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 ships with it
13 files 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.

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.

prompting:scan is a skill published in the GitHub repository bendrucker/claude (18 stars, last pushed today), licensed MIT. It adds 62 tokens to every session and 1,712 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
