Implement Spec
Build the active spec to completion, one reviewable pass at a time. The spec is the source of truth, but the architecture is allowed to improve when the code teaches you the plan is stale.
A pass (usually one slice) is a commit checkpoint, not a stopping point. The job is the whole spec — every slice, every global TODO — not the first green commit. Finishing a pass means starting the next one, not handing back to the user. Only stop when the spec is fully implemented (or a genuine blocker needs a decision only the user can make).
Work in parallel wherever the graph allows. Do not walk the ladder one slice at a time when slices are independent. Read the spec's dependency graph as a wavefront and delegate independent passes to subagents that run concurrently (see Rules) — you orchestrate and integrate; only serialize what genuinely depends on prior work.
Workflow
-
Read the repo README, the spec README, and the next slice before editing. Load any skills named by the spec. Identify the current pickup point, global TODOs, required gates, and what must stay green. If a multi-slice spec lacks a live handoff prompt, add one before the first pass ends.
-
Reconcile the plan with the current code. If the slice would preserve a development-only shim, duplicated type, weak wrapper, or obsolete path, replace it with the simpler architecture and update the spec handoff.
-
Implement one coherent pass: usually one slice, one vertical checkpoint, or one architecture correction. Keep the review surface small enough to audit.
-
Verify the actual contract. For behavior changes, run the focused unit tests first; for browser-visible work, use the real browser/harness and inspect screenshots so the subject is framed and readable, not merely nonblank. A visual CHANGE carries two extra proofs before you claim it: a byte/pixel diff against the pre-change baseline on the production route (static checks and re-anchored assertions all pass on a no-op — a palette pass once shipped "verified" while the production frame was byte-identical), and an unprimed screenshot-critique — at the user's reported framing when the pass answers their visual bug report — before declaring it fixed; the implementer's eyes are primed by the fix and repeatedly pass what fresh eyes catch. Never weaken an existing default gate or repin a failing contract without proving the old contract is wrong.
-
Review the change list and clean up after every pass, before committing. Read
git status/git diff --statline by line and account for every path: one-off probes, shot scripts, scratch files,nohup.out, ad-hoc screenshot dirs, and SPIKE/debug notes never enter a commit — scratch stays out of the tree; review evidence belongs in the spec'sassets/; anything else gets deleted. A file you can't name the durable purpose of does not ship. Delegated agents leak these; the integrating reviewer re-checks the merged tree with the same eye.Sizing the pass — measuring what it cost and reworking it when the line count is out of proportion to the behaviour it delivers — belongs to the shape pass in step 6, under refactor-clean.
-
Run review at the end of every pass, before committing. It sequences the three closeout lenses — refactor-clean on the shape, code-review on the settled diff, write-docs on what the change touched — and you apply the fixes from all three. Long specs are where sediment compounds, so hold the shape pass to this pass's own output: dev-only shims, duplicated concepts, parallel abstractions, and compatibility wrappers it introduced collapse into the clean contract with one owner, so the code reads as designed today, not tacked on. Last, run audit-choices on the cleaned pass — a pure audit that appends every decision made where the spec was silent (your own, and each delegated subagent's when integrating) to the spec's choices ledger (
specs/<feature>/choices.md) with verdicts, changing no code itself. You act on its findings: redo unsound choices from their corrected decisions, adopt the recorded provisional call on any user-only entry — the audit never blocks the run. Rerun the affected checks, then commit only the focused changes from this pass. -
Update the spec README's "Next Agent Prompt": status, completed work, next pickup point, blockers, changed gates, and any architecture decision that changed the plan.
-
Run a maintenance checkpoint as part of the loop, not as endgame cleanup. Trigger it after a red pass, after every two or three slice commits, after a rebase/resume/compaction, before changing feature areas, when evidence invalidates the plan, when the handoff contradicts the TODO/graph, when the choices ledger's entries cluster around one slice, or when the active prompt grows hard to scan. Long specs bloat repeatedly; cleanup is a normal pass, not a cosmetic chore.
A checkpoint cleans both plan and code before more feature work:
- Shorten the README handoff to one current pickup, one priority order, and one compact evidence ledger; move play-by-play into slice files or assets.
- Correct completed/rejected/next markers; delete stale TODOs, stale acceptance claims, duplicated status sections, and obsolete prompts.
- Re-rank remaining work so the next red/high-risk contract is explicit, and demote branches that are not on that path.
- Reslice any still-red, overloaded, or foggy slice into smaller independently verifiable passes before implementing past it.
- Delete or collapse scaffolding from earlier passes when it no longer owns a real contract.
- If the work feels off-track, ask a fresh review/subagent to audit spec shape and priority order, then apply the fixes.
Commit the checkpoint as its own focused pass when cleanup changes the spec, code shape, or handoff enough that future agents would otherwise inherit stale context. It is done only when a fresh agent can read the README handoff, TODO, and slice graph and choose the same next action without conversation history.
-
Continue. If any slice or global TODO is still open, go straight back to step 1 for the next one — same session, no pause for acknowledgement. Keep looping until every TODO is closed.
-
Run review once more over the whole spec. The per-pass reviews each judged one slice against the code as it stood then; this one judges the finished feature. Scope it to the spec's full diff, not the last pass — that is the only scope where duplication spread across slices, a shape that only reads wrong once every slice has landed, and docs that describe increments instead of the feature are visible at all. Apply the fixes, rerun the gates, commit.
-
Consolidate the choices ledger, then close. When the last slice lands, the
choices.mdyou've been appending to per pass is build-order sediment: entries banked early carry "provisional — revisit in slice N" verdicts that a later pass silently resolved, entries a later pass reverted still sit there, and the same choice may appear twice. The per-pass rule "banked is settled, never re-listed" is what let that drift accumulate — so the final consolidation is its deliberate exception. Before archiving, rewritechoices.mdfrom scratch as the final ledger: re-audit every banked choice against the final shipped code (not the pass it landed in), collapse each provisional/needs-later entry to its actual end state, drop anything a later pass superseded or reverted, and merge duplicates. Keep it choices only — no gate results, e2e evidence, or review-finding narration; those are reported elsewhere and are not decisions the user now owns. Present it per audit-choices: grouped by verdict, ranked least-confident-first, every entry ELI5 and standalone. Then close the spec with close-spec.
Rules
- Delegate independent work to subagents so passes run in parallel. The spec's dependency graph is the map: whenever two or more slices, branches (e.g. frontend vs backend), sub-slices, replication spikes, or recon tasks have no unmet dependency on each other, hand them to subagents that run concurrently (spawn them in one message) instead of doing them yourself in sequence. Give each subagent its own git worktree when they touch files in parallel so their diffs don't collide, and keep work that shares the same files or API seam on a single agent to avoid merge chaos. Each delegated unit still owns its full pass — implement, verify, review, focused commit — and you integrate the results, resolve conflicts, rerun the affected gates on the merged tree, and keep the Next Agent Prompt coherent. Only serialize what the graph says must be serial; never idle a lane waiting on an unrelated one.
- Treat backward compatibility as non-goal for unshipped/dev scaffolding. Delete old paths, wrappers, aliases, fallback modes, and stale tests when the new architecture replaces them.
- Do not let tests get easier by accident. A split harness or new runner must preserve the old default coverage unless the spec explicitly changes it.
- Commit every clean pass, then immediately begin the next one. A green commit is a checkpoint, not permission to stop. If a pass is not green, do not commit it as finished; report the failing contract and exact evidence.
- Do not stop while work remains. "Slice N is done and committed" is not a finished task while later slices or TODOs are open — a single completed slice is a reason to continue, never to hand back. The only legitimate early stops are: a hard blocker that needs a user-only decision, a gate that cannot be made green with an honest fix, or the user interrupting. Running low on context is not a stop — update the handoff and keep going. When you must stop, say exactly which slice is next and why you paused.
- Keep visual evidence honest: contact sheets, GIFs, screenshots, and baselines must show the thing being judged at the intended camera/framing.
- Sweep every user-visible surface implied by the slice. A model, state, or data change is not done if the main view, cards, menus, reports, and verification fixtures now tell different stories.
- When the implementation touches shared behavior, leave docs or spec rationale using write-docs principles: durable invariants and pointers, not copied inventories.
- For long specs, keep the spec itself reviewable as an invariant. Do not let the README become a transcript of every attempt; keep one current handoff, one TODO/graph, and one compact evidence ledger, with details in slice files or assets.
- Human checkpoints never block. At a slice's review or sign-off gate, open the relevant shots with preview-shots, state the decision and the options, and give the user ~5 minutes to weigh in — keep building other non-blocked work meanwhile, never idle. If they don't answer, make the call yourself on the evidence, record the decision and its rationale in the spec (the checkpoint's resolution), and keep going — and close the shots you opened (preview-shots cleans up Preview) so a long unattended run never piles up windows. A goal or implementation NEVER stops to wait on the user; it documents the assump

# Implement Spec
Build the active spec to completion, one reviewable pass at a time. The spec is
the source of truth, but the architecture is allowed to improve when the code
teaches you the plan is stale.
A pass (usually one slice) is a **commit checkpoint, not a stopping point.** The
job is the whole spec — every slice, every global TODO — not the first green
commit. Finishing a pass means starting the next one, not handing back to the
user. Only stop when the spec is fully implemented (or a genuine blocker needs a
decision only the user can make).
**Work in parallel wherever the graph allows.** Do not walk the ladder one slice
at a time when slices are independent. Read the spec's dependency graph as a
wavefront and **delegate independent passes to subagents that run concurrently**
(see Rules) — you orchestrate and integrate; only serialize what genuinely
depends on prior work.
## Workflow
1. Read the repo README, the spec README, and the next slice before editing.
Load any skills named by the spec. Identify the current pickup point, global
TODOs, required gates, and what must stay green. If a multi-slice spec lacks
a live handoff prompt, add one before the first pass ends.
2. Reconcile the plan with the current code. If the slice would preserve a
development-only shim, duplicated type, weak wrapper, or obsolete path,
replace it with the simpler architecture and update the spec handoff.
3. Implement one coherent pass: usually one slice, one vertical checkpoint, or
one architecture correction. Keep the review surface small enough to audit.
4. Verify the actual contract. For behavior changes, run the focused unit tests
first; for browser-visible work, use the real browser/harness and inspect
screenshots so the subject is framed and readable, not merely nonblank.
A visual CHANGE carries two extra proofs before you claim it: a
byte/pixel diff against the pre-change baseline on the production route
(static checks and re-anchored assertions all pass on a no-op — a
palette pass once shipped "verified" while the production frame was
byte-identical), and an unprimed
[screenshot-critique](../../visual/screenshot-critique/SKILL.md) — at the
user's reported framing when the pass answers their visual bug report —
before declaring it fixed; the implementer's eyes are primed by the fix
and repeatedly pass what fresh eyes catch.
Never weaken an existing default gate or repin a failing contract without
proving the old contract is wrong.
5. **Review the change list and clean up after every pass, before committing.**
Read `git status`/`git diff --stat` line by line and account for every path:
one-off probes, shot scripts, scratch files, `nohup.out`, ad-hoc screenshot
dirs, and SPIKE/debug notes never enter a commit — scratch stays out of the
tree; review evidence belongs in the spec's `assets/`; anything else gets
deleted. A file you can't name the durable purpose of does not ship.
Delegated agents leak these; the integrating reviewer re-checks the merged
tree with the same eye.
Sizing the pass — measuring what it cost and reworking it when the line count
is out of proportion to the behaviour it delivers — belongs to the shape pass
in step 6, under [refactor-clean](../refactor-clean/SKILL.md).
6. Run [review](../review/SKILL.md) at the end of every pass, before committing.
It sequences the three closeout lenses — refactor-clean on the shape,
code-review on the settled diff, write-docs on what the change touched — and
you apply the fixes from all three. Long specs are where sediment compounds,
so hold the shape pass to this pass's own output: dev-only shims, duplicated
concepts, parallel abstractions, and compatibility wrappers it introduced
collapse into the clean contract with one owner, so the code reads as designed
today, not tacked on. Last, run
[audit-choices](../audit-choices/SKILL.md) on the cleaned pass — a pure
audit that appends every decision made where the spec was silent (your own,
and each delegated subagent's when integrating) to the spec's choices
ledger (`specs/<feature>/choices.md`) with verdicts, changing no code
itself. You act on its findings: redo unsound choices from their corrected
decisions, adopt the recorded provisional call on any user-only entry — the
audit never blocks the run. Rerun the affected checks, then commit only the
focused changes from this pass.
7. Update the spec README's "Next Agent Prompt": status, completed work, next
pickup point, blockers, changed gates, and any architecture decision that
changed the plan.
8. Run a **maintenance checkpoint** as part of the loop, not as endgame cleanup.
Trigger it after a red pass, after every two or three slice commits, after a
rebase/resume/compaction, before changing feature areas, when evidence
invalidates the plan, when the handoff contradicts the TODO/graph, when the
choices ledger's entries cluster around one slice, or when the
active prompt grows hard to scan. Long specs bloat repeatedly; cleanup is a
normal pass, not a cosmetic chore.
A checkpoint cleans both plan and code before more feature work:
- Shorten the README handoff to one current pickup, one priority order, and
one compact evidence ledger; move play-by-play into slice files or assets.
- Correct completed/rejected/next markers; delete stale TODOs, stale
acceptance claims, duplicated status sections, and obsolete prompts.
- Re-rank remaining work so the next red/high-risk contract is explicit, and
demote branches that are not on that path.
- Reslice any still-red, overloaded, or foggy slice into smaller independently
verifiable passes before implementing past it.
- Delete or collapse scaffolding from earlier passes when it no longer owns a
real contract.
- If the work feels off-track, ask a fresh review/subagent to audit spec shape
and priority order, then apply the fixes.
Commit the checkpoint as its own focused pass when cleanup changes the spec,
code shape, or handoff enough that future agents would otherwise inherit stale
context. It is done only when a fresh agent can read the README handoff, TODO,
and slice graph and choose the same next action without conversation history.
9. **Continue.** If any slice or global TODO is still open, go straight back to
step 1 for the next one — same session, no pause for acknowledgement. Keep
looping until every TODO is closed.
10. **Run [review](../review/SKILL.md) once more over the whole spec.** The
per-pass reviews each judged one slice against the code as it stood then; this
one judges the finished feature. Scope it to the spec's full diff, not the last
pass — that is the only scope where duplication spread across slices, a shape
that only reads wrong once every slice has landed, and docs that describe
increments instead of the feature are visible at all. Apply the fixes, rerun
the gates, commit.
11. **Consolidate the choices ledger, then close.** When the last slice lands, the
`choices.md` you've been appending to per pass is build-order sediment: entries
banked early carry "provisional — revisit in slice N" verdicts that a later pass
silently resolved, entries a later pass reverted still sit there, and the same
choice may appear twice. The per-pass rule "banked is settled, never re-listed"
is what let that drift accumulate — so the final consolidation is its deliberate
exception. Before archiving, **rewrite `choices.md` from scratch** as the final
ledger: re-audit every banked choice against the **final shipped code** (not the
pass it landed in), collapse each provisional/needs-later entry to its actual
end state, drop anything a later pass superseded or reverted, and merge
duplicates. Keep it **choices only** — no gate results, e2e evidence, or
review-finding narration; those are reported elsewhere and are not decisions the
user now owns. Present it per [audit-choices](../audit-choices/SKILL.md): grouped
by verdict, ranked least-confident-first, every entry ELI5 and standalone.
*Then* close the spec with [close-spec](../close-spec/SKILL.md).

- **Delegate independent work to subagents so passes run in parallel.** The
spec's dependency graph is the map: whenever two or more slices, branches (e.g.

each subagent its own git worktree when they touch files in parallel so their

Start with one small task
- 1Read the source. Confirm the input, expected output, dependencies and permissions.
- 2Ask your agent for a plan. Approve setup and any costs before running a small isolated test.
- 3Check the output and changed files. Report only what actually ran; keep the source revision for reproduction.
Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.

Preserve the core workflow, adapt paths to this repo, and keep the rule scoped to tasks where it is relevant. Skill purpose: Implement an existing spec through committed passes. Use for long or multi-pass specs that need maintenance checkpoints to periodically clean code, handoffs, priorities, and plan bloat before drift accumulates.
