MUST BE USED when user asks to: implement a feature, fix a bug, write code, add functionality, build something, code this, make changes. Implements code changes — when used within the SDLC workflow, PR creation is handled separately by pr-preparer.

MUST BE LOADED for any coding task: implementing features, fixing bugs, writing code, refactoring, or making changes. This skill provides the mandatory step-by-step SDLC (Software Development Lifecycle) workflow for orchestrating development using specialized skills and sub-agents. Load this skill when the user asks to 'add', 'create', 'build', 'fix', 'update', 'change', 'implement', or 'refactor' anything.
MUST BE LOADED BEFORE modifying docs/tasks.md, docs/changes/, or task lists. Also load when user mentions tasks.md, changes/, 'the task file', specs, or discusses tasks/tracking. Triggers include: 'add a task', 'update tasks', 'mark as done', 'mark complete', 'track this', 'next task', 'what's next', 'work on next', create tickets/issues, 'add a feature', 'improve X to allow Y', plan features, break down tasks, or ANY project/task management discussion. This skill handles all task tracking through docs/tasks.md, docs/changes/ task lists, or external tools (GitHub Issues, Jira).
Spawn a coordinated sub-agent team to implement a spec or multi-task feature in parallel. Use when user says '/team', 'use a team', 'parallel implementation', 'work on multiple tasks', or provides a spec/issue that requires coordinated multi-PR work. The main session acts as coordinator — no code, no commits, only delegation and quality control.
Write, update, and maintain living specification documents and propose change documents. Use when user says 'write a spec', 'create a spec', 'spec out', 'update spec', 'spec this', 'design a feature', 'write a feature spec', or needs to create/modify specs in docs/specs/ or propose changes in docs/changes/. Handles the complete spec lifecycle: creation, updates, gap analysis, and change proposals.
Run OpenAI Codex's AI code review LOCALLY via the `codex` CLI BEFORE opening a PR (part of pre-PR self-review). Runs one-shot, reviewing the current branch against main, prints findings to stdout, and you resolve them before the PR is opened. Use during pre-PR self-review, alongside fx-dev:coderabbit-review.
Process and resolve GitHub Copilot automated PR review comments. Use when the user says "check copilot review", "handle copilot comments", "resolve copilot feedback", "address copilot suggestions", or mentions Copilot PR comments. Also use after PR creation when Copilot has left automated review comments.

When invoked by the SDLC workflow (as a sub-agent), the coder is implementation-only: write code, run tests, commit. Do NOT create PRs — the SDLC orchestrator delegates that to pr-preparer. When invoked directly by the user (not via SDLC), the coder owns the full lifecycle including PR creation.
feature/<issue>-<name> from mainfeature/<issue>-<name>-part-<n> for logical separationWhen invoked from SDLC: Stop after step 4 (implement with tests + commit). Do NOT create PRs or launch reviewers.
#<number>, no waves/phases. A commit subject auto-links #N to PR/issue #N, and it propagates into the PR title (GitHub pre-fills the title from a single commit's subject) and the squash-merge commit subject — so the PR-title rule applies here too: never put #<number> (#4, (#4), #123) in a commit subject unless N is a real PR/issue ref on this repo, and never use a wave/phase/step/change-doc number there. See the fx-dev:github skill's "#<number> PR-Title Rule".NEVER skip tests. Using test.skip, it.skip, describe.skip is FORBIDDEN.
If a test cannot pass:
If tests require infrastructure (auth, database, APIs):
Remember: Ship working code in small PRs. You own the entire lifecycle - implement, review, fix, and prepare for user approval.
