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

cull-release-verify 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

Cull Release Verify

Principle

Reconstruct release truth from immutable public evidence. Verification is read-only by default.

Verify

  1. Resolve the Cull checkout and select the explicit version or latest public release.
  2. Run npm run release:cull -- state show --version "$VERSION" --json and parse exactly one JSON envelope.
  3. Bind the annotated Git tag object and peeled commit to the published release, authenticated workflow run, provenance, and required asset inventory.
  4. Download artifacts to an isolated temporary directory. Run Cull's exact artifact verifier; check updater signature, SHA-256 checksums, DMG contents, embedded version and architecture, codesign, Gatekeeper, and notarization staple.
  5. Compare Homebrew version and SHA-256 with public provenance and require its promotion evidence.
  6. Report version, commit, tag object, workflow, asset hashes, release URL, tap commit, installed-version evidence, launch evidence, and mismatches.

Default to no installation. When the user explicitly requests an install smoke, use an isolated location and preserve any existing app. Never edit release state, the GitHub release, tags, the tap, system Applications, or cull.db.

Files

What ships with it

1 file 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.

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.
