A collection of skills for Claude Code. Each skill adds a slash command or automation that extends what Claude can do in your terminal.
| Skill | Command | Description |
|---|---|---|
| Council | /council |
Virtual advisory board of domain experts. Feynman is always present to ask first-principles questions. |
| Council Grill | /grill |
Grill-me meets the council: an interrogator walks the decision tree asking the whole frontier each round, the council answers and pushes back, and the loop runs until every decision is settled and a spec falls out. Council runs on the Codex MCP where available, otherwise two Fable-class agents taking turns. |
| Interrogation Protocol | /interrogate |
Cognitive lens analysis — 36 operational protocols across design, engineering, business, product, refactoring, security, and AI. Not persona simulation; transferable methods. |
| Auto-Archive | /archive |
Auto-archive sessions at 60% context window with keyword-indexed summaries for LLM discoverability. |
| Cognitive Mesh | /mesh |
BDI+OODA cognitive mesh for structured problem-solving. Beliefs-Desires-Intentions manage internal state, Observe-Orient-Decide-Act drive execution. The mesh tightens each cycle until the problem is solved. Execution, not analysis. |
| Picasso Bull | /picasso |
Progressive code refinement through deliberate waves, inspired by Picasso's Bull lithograph series. Wave 1 makes behavior and invariants explicit; later waves remove non-essential complexity while preserving them. |
| Rails PBT | /rails-pbt |
Property-based tests for Rails with the pbt gem. Ranks targets by blast radius, writes a property catalog for human review, then generates plain RSpec property specs from eight recipes and triages the failures. |
