Use when the user wants to make a pytest suite faster, profile slow tests or fixtures, find unused or mis-scoped fixtures, consolidate duplicate test tracks, migrate to typed parametrize, or apply safe test speedups. Triggers on phrases like "speed up my tests", "why are my tests slow", "profile pytest", "optimize the test suite", "find slow fixtures", "my fixtures are slow", "which fixtures are unused", "the test suite takes too long", or "parallelize my tests". Runs a resumable four-phase pipeline (scan, benchmark, plan, execute) that measures before it mutates and applies each speedup as its own verified commit. Does not edit the suite until a speedup clears the noise band and a safety gate.
Use when the user wants multiple independent ideas, alternatives, or approaches from different AI models for a creative prompt, design question, or open-ended problem. Triggers on phrases like "brainstorm", "give me ideas", "multiple approaches", "what are my options", or "explore alternatives"
Use when the user wants to brainstorm and refine developer-experience, documentation, or tooling UX work through a "serene DX" aesthetic lens — three fixed variants that sweep across DX Bliss (frictionless), DX Serenity (calm clarity), and DX Sublimity (showcase-grade novelty). Triggers on phrases like "serene bliss", "DX bliss", "DX serenity", "DX sublimity", "reader happiness", "make this serene", "serene developer experience", or "serene DX". Runs the /weave:serene-bliss command, which dispatches three lens variants across all available models in parallel and judges each refine pass with a multi-model panel (Claude + Antigravity + GPT, peer-only averaging).
Delegate a task to Google's Gemini via the Antigravity (agy) CLI. Use this skill when the user explicitly asks to use Antigravity, agy, Gemini, or Google's model for a task, or when you determine that Gemini would provide better results for a specific task. Detects the agy binary, falls back to the gemini CLI, then to agent --model gemini-3.1-pro if neither is available.
Use when running a prompt through Google's Gemini directly. A manual invocation point for /model-cli:agy — the Antigravity (agy) CLI supersedes the standalone gemini CLI (Google retires it on 2026-06-18), so both entry points resolve through the same backend chain: agy, then the gemini CLI, then agent --model gemini-3.1-pro.
Delegate a task to OpenAI's GPT via the Codex CLI. Use this skill when the user explicitly asks to use Codex, GPT, or OpenAI for a task, or when you determine that GPT would provide better results for a specific task (e.g., tasks requiring OpenAI-specific strengths). Detects the codex binary, falls back to agent --model gpt-5.4-high if unavailable.
TDD xfail workflow with hermetic reproduction guards — reproduce a bug as a strictly-expected-to-fail test, verify the reproduction is genuine, apply a fix with diff-gate enforcement, and remove the xfail marker. Use when fixing bugs that need strict proof the test fails for the right reason, not because a mock is misconfigured. Triggers on "xfail", "strict xfail", "hermetic TDD", "reproduce with xfail", or "expected failure workflow".
Use when the user wants to generate multiple original ideas from different AI models then iteratively judge, weave, and refine them into the best possible result across multiple passes. Triggers on phrases like "brainstorm and refine", "generate ideas then improve", "explore options then synthesize", or "brainstorm then polish"
