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

castorini-release 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/preflight.sh), 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.

What it actually says

Castorini Release

PyPI/TestPyPI publish workflow for nuggetizer, ragnarok, rank_llm, and umbrela.

Start with the reference checklist and use the bundled preflight script before uploading anything.

Reference Files

  • references/pypi-checklist.md — Step-by-step checklist with commands
  • references/release-sequence.md — Supported repos and the high-level release sequence

Preflight Script

Run the preflight checks before publishing:

bash skills/castorini-release/scripts/preflight.sh <repo-path>

This verifies:

  • Package builds successfully
  • twine check passes (metadata, description rendering)
  • No uncommitted changes
  • Version is bumped from the last release

Gotchas

  • All four repos use bumpver; confirm the version change landed in the tracked files before you build.
  • uv build should be run from the package root, not from the monorepo root or a skill directory.
  • A TestPyPI upload only proves packaging and upload credentials; it does not guarantee PyPI will accept the same distribution later.
  • TestPyPI installs often need --extra-index-url https://pypi.org/simple/ because transitive dependencies may not exist on TestPyPI.
  • Tagging rules and release-note locations are not fully standardized across the repos, so verify the target repo before creating the final tag.
Files

What ships with it

3 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.

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.
