feat(work): pnpm work decompose subcommand
Closes the gap surfaced by the user: `pnpm work` usage referenced
`decompose` (via docs + the to-prd skill) but the subcommand was
never built. Mirrors `pnpm work dispatch`'s shape.
scripts/work/decompose.mjs (new):
- validatePrdForDecompose(prdPath) — refuses draft (must go
through human review first), in-review (review incomplete),
shipped (epic already exists); accepts only approved
- printDecomposePlan(prdId, prdPath, frontmatter) — print-mode
output showing the PRD's eligibility + sandcastle invocation
plan + auth modes
- executeDecompose(prdId, prdPath, prdText) — invokes sandcastle
with .sandcastle/decomposer.prompt.md, passing PRD_FILE_CONTENT
promptArg. The decomposer agent writes the epic + per-story
files to disk on a sandcastle branch the human can review
- runCli(args, { workRoot }) — entry point used by cli.mjs
- Direct invocation also supported (mirrors dispatch.mjs's
invokedDirectly guard, NEW pattern after this commit)
scripts/work/decompose.test.mjs (new, 9 tests, all green):
- validatePrdForDecompose: accepts approved; rejects draft,
in-review, shipped, unknown status, missing file
- runCli: writes error + returns 1 on missing PRD; writes error
+ returns 1 on draft PRD; prints plan + returns 0 on approved
scripts/work/cli.mjs:
- Adds `decompose` subcommand to usage + dispatch
- Usage formatting realigned for the 3-line subcommand block
scripts/work/dispatch.mjs:
- **Fix** the bug surfaced by the user: dispatch.mjs's CLI ran
as a top-level side effect whenever any of its exports was
imported. decompose.mjs imports resolveClaudeAuth from it, so
importing decompose.mjs printed "No ready task to dispatch."
Added an `import.meta.url === \`file://${process.argv[1]}\``
guard so the CLI only runs when invoked directly. This unblocks
cross-import without side effects.
Smoke-tested end-to-end:
- `pnpm work decompose` (no id) prints usage + exits 2
- `pnpm work decompose 2026-05-13-binder-wrap-helper` prints the
decompose plan with status: approved (eligible)
- 9/9 unit tests green
- dispatch.mjs's existing direct-invocation path unchanged
