Use when the user wants to execute tasks autonomously, run compounder on a tasks.md file, start autonomous development, compound through a task list, or implement tasks iteratively. Guides autonomous task execution using compound loops.

TDD Green Phase expert. Activate when: - Test is written and failing, need to make it pass - User mentions "make test pass", "green phase", "minimal implementation" - Writing implementation code to satisfy tests - Questions about simplest solution to pass tests Auto-triggers on: making tests pass, minimal implementation, green phase

This skill should be used when creating or extending ActorSheet/ItemSheet classes, implementing getData or _prepareContext, binding events with activateListeners, handling drag/drop, or migrating from ApplicationV1 to ApplicationV2. Covers both legacy V1 and modern V2 patterns.

Use when working with Cloudflare Workers, edge computing, serverless functions, or any Cloudflare platform services.

Generate breadboard circuit mockups and visual diagrams using HTML5 Canvas drawing techniques. Use when asked to create circuit layouts, visualize electronic component placements, draw breadboard diagrams, mockup 6502 builds, generate retro computer schematics, or design vintage electronics projects. Supports 555 timers, W65C02S microprocessors, 28C256 EEPROMs, W65C22 VIA chips, 7400-series logic gates, LEDs, resistors, capacitors, switches, buttons, crystals, and wires.

This skill should be used when the user asks to "add a database table", "create a new context", "query the database", "add a field to a schema", "validate form input", "fix N+1 queries", "preload this association", "separate these concerns", or mentions Repo, changesets, migrations, Ecto.Multi, has_many, belongs_to, transactions, query composition, or how contexts should talk to each other.

Expert at crafting clear, meaningful git commit messages following conventional commit standards and repository conventions. Use when user asks to create commit messages, write commits, or needs help with git commit text. Analyzes git diffs and repository history to generate contextual, well-structured commit messages.

Generate summaries of therapy sessions and journal entries at various lengths and for different audiences. Supports action item extraction, highlights reels, and session prep. Use for quick recaps, sharing with others, or preparing for your next session.

Automatically extract reusable patterns from Claude Code sessions and save them as learned skills for future use.
