What is skul CLAUDE.md?

Project instructions for Skul, a TypeScript command-line tool for managing AI configuration bundles across several coding tools.

Use them to run development commands and verify formatting, linting, type checking, tests, coverage, and builds.

They provide the commands and checks needed to install dependencies, test the project, check types, build it, and meet continuous-integration requirements.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00243	$0.00243
Opus 5.5	$0.00097	$0.00097
Sonnet 5.5	$0.00049	$0.00049
Haiku 4.5	$0.00024	$0.00024

Security

Grade A, and why

skul CLAUDE.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 2mo 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

Overview

Skul is a TypeScript CLI for managing project-scoped AI configuration bundles across multiple tools (Claude Code, Cursor, Codex, OpenCode). It handles bundle discovery, materialization, registry tracking, stealth mode, and cross-tool translation.

Note: This CLI has not been shipped yet.

Commands

Run pnpm install first — this installs dependencies and sets up the prek pre-commit hooks.

pnpm test           # run tests once
pnpm run typecheck  # type-check without emitting
pnpm run build      # compile to dist/
pnpm run dev        # run CLI via tsx

CI checks

These three commands must pass before pushing — they're what .github/workflows/ci.yml runs:

pnpm run check:ci       # biome lint + format check (no autofix)
pnpm run typecheck      # tsc --noEmit
pnpm run test:coverage  # vitest run --coverage

To autofix lint and formatting issues locally before re-running check:ci, use pnpm run check (which runs biome check --write .).

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.
