Use when the user mentions dspy/DSPy, Signature, Module, teleprompter/optimizer, compile, evaluate, few-shot, RAG, tool use, or local LLM endpoints (Ollama/vLLM/LM Studio).

Use this skill for Pest PHP testing in Laravel projects only. Trigger whenever any test is being written, edited, fixed, or refactored — including fixing tests that broke after a code change, adding assertions, converting PHPUnit to Pest, adding datasets, and TDD workflows. Always activate when the user asks how to write something in Pest, mentions test files or directories (tests/Feature, tests/Unit) or architecture tests. Covers: test()/it()/expect() syntax, datasets, mocking, browser testing, arch(), Livewire component tests, RefreshDatabase, and all Pest 3 features. Do not use for editing factories, seeders, migrations, controllers, models, or non-test PHP code.

Guidance for facet `effect/Sink#transforms` focused on APIs like map, mapEnd, and flatMap. Load after `effect-skill-router` when this facet is the primary owner.

name: CI

This skill allows the agent to interact with live web pages to verify functionality and design.

Guidance for facet `effect/Schema#composition` focused on APIs like HashMap, HashMapIso, and compose. Load after `effect-skill-router` when this facet is the primary owner.

Plans a user-provided feature idea by reading SPEC and code (read-only), analyzing scope, proposing a design aligned with existing architecture, optionally clarifying underspecified requirements with focused questions, and opening a GitHub issue that documents requirements, assumptions, design, subtasks with dependencies, and acceptance criteria—without modifying the repository. Use when the user wants a feature scoped and filed as an issue before any implementation, spec edits, or PR work.
