This skill should be used after productive sessions to extract learnings and route them to appropriate Reusable Intelligence Infrastructure (RII) components. Use when corrections were made, format drift was fixed, new patterns emerged, or the user explicitly asks to "harvest learnings" or "capture session intelligence". Transforms one-time fixes into permanent organizational knowledge by implementing updates across multiple files.

Execute agentic coding tools directly via bash commands with output capture. Use this when the user requests to run AI agents (Gemini, Claude Code, etc.) and get their results directly.

Manages practice rules. Use when user states a preference or approach, or asks to add/modify rules for coding, architecture, tooling, or best practices.

Use this skill when creating new skills via forced conceptual collision of existing patterns. Duct-tapes jank-builder to super-collider for autopoietic meta-skill generation.

Documentation organization, maintenance, and cleanup. USE WHEN: organizing docs, cleaning project root, updating documentation, checking for redundancy, maintaining docs structure. NOT FOR: technical implementation (use relevant technical skill). Examples: <example> Context: User added documentation to wrong location. user: "I added a new API doc file to the root directory" assistant: "I'll use docs-keeper to organize it in the proper docs/ location." <commentary>File organization is docs-keeper responsibility.</commentary> </example> <example> Context: User needs to update docs after code changes. user: "I modified the auth system and need to update the docs" assistant: "I'll use docs-keeper to update the authentication documentation." <commentary>Documentation updates are docs-keeper responsibility.</commentary> </example>
