rook-release: Skill for Claude Code

.claude/skills/chirp/SKILL.md

chirp is a skill for Claude Code from bringfire/rook-release. It costs 95 tokens per session (2,292 once invoked), scanned A, original, MIT.

A tool for adding one Chirp component to a Grasshopper canvas. Components can serve roles such as planner, interpreter, critic, narrator, classifier, gate, or editor.

In plain words
What is it for?
It helps create a specified Chirp component when you have a design context and a component category.
Why use it?
It provides a direct way to place a needed Chirp role into a Grasshopper design.

Skill for Claude Code

Written for Claude Code: installed under .claude/.

This is bringfire/rook-release's own configuration. It tells Claude Code how to work on rook-release itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything rook-release configures →

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

chirp 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 26d 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.

Chirp — Single Component

Create one Chirp component on the GH canvas with the correct category, pins, signature, and visual treatment. Every component gets a Reasoning output and an optional Correction input automatically.

Categories

Category Purpose DSPy Module Typical Inputs Typical Outputs
planner Brief → structured parameters ChainOfThought Brief (string) Domain-specific params (typed)
interpreter Upstream Reasoning → domain-specific parameters ChainOfThought Reasoning (string) + context Domain-specific params (typed)
critic Multiple Reasonings → conflict detection MultiChainComparison 2+ Reasoning inputs Conflicts (string), Score (float), Coherent (bool)
narrator Multiple Reasonings → design narrative ChainOfThought 2+ Reasoning inputs Narrative (string), Summary (string)
classifier Data → categorical decision Predict Data + optional Intent (string) Category (string), Confidence (float)
gate Reasoning → rule activations Predict Reasoning (string) Boolean/enum flags
editor Reasoning + Correction → reconciled Reasoning ChainOfThought Reasoning (string) + Correction (string) Reasoning only (reconciled)

Universal Pins (auto-added to ALL categories)

Outputs:

  • Reasoning (string) — LLM chain-of-thought. Always present. Reserved name.

Inputs:

  • Correction (string, optional) — Human override. When empty, no effect. When connected to a Panel with text, the LLM prioritizes it over upstream assumptions and explains the reconciliation in its Reasoning output.
  • Freeze (bool, optional) — When true, the component replays its frozen result and never calls the model; with no frozen result it uses deterministic defaults and warns. Default false.
  • Frozen (string, optional) — The frozen store: one entry per list item (the last successful model response for that item), written by the component itself into this pin's persistent data so it is saved in the .gh file and travels with it. Leave it unconnected; wire a Panel only to supply a store by hand.

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.

chirp is a skill published in the GitHub repository bringfire/rook-release (6 stars, last pushed yesterday), licensed MIT. It adds 95 tokens to every session and 2,292 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
