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

readme 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 8d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/banner.py, scripts/fetch_commons.py, scripts/inspect_project.py, …), 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 — 159 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Write Me a README

Create a trustworthy repository front page from project evidence. Write for a new visitor who must understand the value, verify the fit, and reach a working first result quickly.

Resolve every bundled path relative to this SKILL.md. Run scripts with the current Python interpreter; do not assume the skill is installed at a fixed global path.

Operating contract

  • Produce or update README.md in the target project unless the user requests audit-only output.
  • Inspect before writing. Treat source files, manifests, tests, CI, examples, existing docs, and user statements as evidence in that order.
  • Never invent commands, compatibility, performance, adoption, maintainers, security posture, or production readiness.
  • Never copy prose, slogans, banners, or layouts from another repository. Learn patterns, then create original content and visuals.
  • Preserve useful existing material, deliberate terminology, status warnings, legal notices, and user-authored sections.
  • Keep source-code changes out of scope. Add only README-related files unless the user explicitly expands the task.
  • Do not promise search ranking, GitHub Trending placement, virality, or adoption. Optimize discoverability, comprehension, conversion, and trust.
  • Prefer a complete first pass over blocking questions. Ask only when a missing choice would materially change the result and cannot be inferred safely.

1. Establish scope

Infer these choices from the request and repository:

  • Mode: create, refresh, redesign, translate, or audit-only.
  • Audience: end user, library consumer, operator, contributor, learner, or mixed.
  • Language: preserve the established README language; otherwise use the dominant project-doc language; otherwise default to English.
  • Voice: honor an explicit style request; otherwise infer the established brand voice and default to confident-friendly. Use one primary profile plus at most one modifier, such as professional + warm or playful + concise.
  • Visuals: generate a banner for a new README by default. Keep an existing high-quality branded hero unless replacement is requested. Honor text-only requests.
  • Depth: keep a small tool concise; move extensive concepts, API reference, and contributor internals to existing or new docs/ pages only when needed.

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.
