Internal reference skill — coding standards and patterns for developer agents. Not user-invocable.
Close out work by committing local changes, pushing, waiting for green CI, and merging the PR. Universal — works on any branch with an open PR; no task structure required. Use when asked to 'merge the PR', 'ship it', 'merge and close', 'commit push merge', 'finalize the PR', 'land it on main', 'we're done — close it out', or whenever the user signals end-of-work and the next step is to merge. If (and only if) the current work is one phase of a multi-phase task in `tasks/**/phase-N-*/`, also make upcoming phase tech-decomposition documents accurate for the implementation that just landed by adding handoff notes or updating stale assumptions before merging — otherwise this step is silently skipped. Make sure to use this skill whenever the user signals end-of-implementation and wants the changes merged — even if they don't say the word "skill". NOT for opening a new PR (use plain `gh pr create`). NOT for addressing review comments (use /prc). NOT for preparing a session handoff to a fresh context (use /ph).
Use when a plan, design, or discovery document needs stress-testing for hidden assumptions, scope gaps, unresolved branches, or ambiguous wording; also when the user explicitly says "grill me".
Internal reference skill — shared conventions for all code review agents. Not user-invocable.
Implements a feature from a technical decomposition using TDD, keeping the task document updated and handing off cleanly to review. Use when starting, continuing, or resuming implementation from a tech-decomposition or task directory. Trigger: 'implement this task', 'start implementation', 'continue/resume implementation', 'build from the tech decomposition', or after /ct produces a decomposition. NOT for creating the plan (/ct), feature discovery (/nf), small untracked changes (/si-quick or /quick), or code review (/sr).
Use when asked to review code before merge or review a PR, branch, commit range, task path, or current working tree. Trigger on requests like 'review PR', 'review my changes', 'review this branch', 'is this ready to merge', or other pre-merge review requests. Supports task/spec-aware review when task docs exist. NOT for addressing review comments (use /prc).
Test-driven development with red-green-refactor loop using vertical slices. Use when building features or fixing bugs with TDD, when /si or /si-quick needs canonical TDD discipline, when user mentions "red-green-refactor", "tracer bullets", "test-first", or asks for integration-style tests. Forbids horizontal slicing (all tests then all implementation).
Run Google Antigravity CLI (agy) for web-grounded research, cross-AI review, or validation. Use when asked for 'ask antigravity', 'antigravity review', 'agy search', 'use antigravity', or when you need Google Search grounding or a different AI perspective. NOT for interactive conversations (driven one-shot only).
