# build — TDD story implementation Cycle per story: plan -> RED -> GREEN -> refactor -> QA -> complete. Full orchestration contract in [`wave-orchestration.md`](../../references/wave-orchestration.md); fan-out rules in [`subagent-fanout.md`](../../references/subagent-fanout.md). Next step: `pact review` (if `steps.review`) or `pact ship`. ## Progress tracking Open a `TodoWrite` list: one item per phase, plus one per wave once the wave plan is known. ## Phase 0 — schema gate `pact schema --gate`. Mismatch -> `/pact:migrate`. ## Phase 1 — scope Parse `$ARGUMENTS`: - a **story path** -> that one story, inline (validate its frontmatter first). - **story ids** (`01-02 01-05`) -> one wave. - **`--epic NN`** -> every non-`done` story of that epic, in waves. - **`--story ID`** -> force inline even if peers exist. - **empty** -> the current spec's non-`done` stories, in waves. If no spec is active, pick interactively from `FEATURE_INDEX.md`. - **`--mode`** sets the execution mode for this run (see Phase 5). No `--mode` -> ask once with `[workflow].default_exec_mode` as the default. A dispatch prompt beginning `MODE: delegated` means this run **is** a `story-implementer` worktree agent — follow `agents/story-implementer.md` and skip the rest of this file. ## Phase 2 — active-spec lock One active spec at a time from here through merge. If another spec's `spec/<id>` branch exists and is unmerged and it is not the spec in scope, **stop**: tell the user to finish it or `pact
