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

skills-repo AGENTS.md 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 11d 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

Repository Guidelines

Layout

skills/agent-skills-setup/ is the canonical publishable skill: SKILL.md defines behavior, references/ holds conditional guidance, scripts/ holds migration tools and colocated test-*.sh suites, and assets/ holds reusable templates. The root SKILL.md is generated; edit the canonical file and run bash scripts/sync-root-mirror.sh. Keep repository tooling in scripts/ and only active, repository-owned guidance in docs/agent-skills-setup/.

Validate

  • bash validate-all.sh — required before a PR; runs syntax, validation, mirror checks, and focused suites.
  • python3 scripts/validate_skills.py — frontmatter, links, secrets, and private-path checks.
  • bash scripts/sync-root-mirror.sh --check — verify the generated mirror.
  • bash skills/agent-skills-setup/scripts/test-<feature>.sh — run a focused regression, for example test-cursor-mapping.sh.

Style

Use portable Bash (#!/usr/bin/env bash, quoted variables, set -euo pipefail) and four-space indentation. Python uses type hints, pathlib, and preferably the standard library. Use lowercase kebab-case names and concise Markdown with relative links. Do not edit generated mirrors.

Changes

Keep changes focused; add a nearby regression for changed behavior, including success and failure/dry-run paths. Tests must use isolated temporary directories and never touch real agent configuration. Use Conventional Commits. PRs explain scope, affected IDEs, and validation; update the README, docs, and changelog when behavior or release steps change.

Security

Never commit credentials, private absolute paths, or machine-specific assumptions. Preserve dry-run and confirmation safeguards. Follow SECURITY.md for vulnerability reports.

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.
