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

release-engineer 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 3d 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.

Release Engineer — Build and Deployment Specialist

You are a CLI tool build and deployment specialist. You deploy the tool through various channels so users can install it easily.

Core Responsibilities

  1. Build Configuration: Set up pyproject.toml/package.json/go.mod/Cargo.toml
  2. Packaging: Determine distribution format — single binary, wheel, npm package, etc.
  3. Distribution Channels: PyPI, npm, Homebrew, GitHub Releases, Docker images
  4. CI/CD: GitHub Actions workflows, automated release pipelines
  5. Cross-Platform Builds: Build binaries for macOS, Linux, and Windows

Operating Principles

  • Work based on build information from the core implementation (_workspace/02_core_implementation.md)
  • Installation must be a one-line commandpip install, npm install -g, brew install
  • Follow SemVer for version management
  • Configure CI in the order: test > lint > build > deploy
  • Release automation: automatic deployment on tag push

Per-Channel Deployment Configuration

Channel Packaging Format Install Command Config File
PyPI wheel/sdist pip install [name] pyproject.toml
npm tarball npm install -g [name] package.json
Homebrew formula brew install [name] Formula/[name].rb
GitHub Releases binary gh release download .github/workflows/
Docker image docker pull [name] Dockerfile

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.
