name	deliver
description	Take one ticket or idea from raw intent to merge-ready (or shipped, when asked): context-first, docs→tests→code, live QA, refactor at three altitudes, semantic commits, diverse-provider review, adversarial pre-ship thinking. Use for "deliver this", "build this ticket", "make it merge-ready", "take this end to end". Trigger: /deliver.

/deliver

One piece of work, end to end, done the way we'd be proud of. This skill is judgment checkpoints, not phase machinery — you own the decomposition, and even the best model skips some of these steps unprompted. Don't.

Context first

Before writing anything: read the ticket and the live code it touches; build real product understanding (who uses this, what breaks if it's wrong); /research best practices when the design has open questions; and pre-factor — if the change lands in messy ground, clean the ground first as its own commit. If the ticket has no goal or acceptance oracle, run /shape (or write the oracle yourself for small work) before building. For product direction, positioning, long-lived workflow, or project-identity changes, read root VISION.md when present; if direction matters and the repo has no credible north star, route to /vision before building. If the goal is still in the user's head, interrogate before shaping with the interrogate-first lens (harnesses/shared/references/interrogate-first.md); one good question beats a guessed plan. Building without an oracle yields plausible garbage. For public API, CLI, UI, performance, compatibility, migration, or operator workflow changes, load harnesses/shared/references/works-critique.md before pre-ship review. For automation, optimization, or refactor pressure, apply harnesses/shared/references/delete-first.md and the synced Ponytail skill (skills/.external/dietrich-ponytail/SKILL.md) before adding surface.

For non-trivial execution, start from the HTML plan artifact when one exists; otherwise author a small one directly from skills/shape/templates/html-plan.html, open it, and use the rendered page to check clarity, sequence, risk, and proof before coding. The plan must stand alone for the executor: hero as the work contract, support sections for alternatives/tradeoffs, acceptance, verification, communication cadence, stop conditions, and useful adversarial review. Include the quality system from harnesses/shared/references/quality-system.md: standards, proof methods, critic topology, and stop rules. The point is visual planning, not a Markdown conversion. Skip only for trivial mechanical fixes, no-browser environments, or explicit operator waiver.

Verification system first (shared AGENTS.md, Layer 1): locate the repo's live-verification harness — the one command that exercises a change against the running thing and emits reviewable evidence. If none exists, building it is the ticket's first milestone, not a detour; every milestone after ships through it. The harness-before-feature session catches the bugs unit tests structurally cannot. For evals, benchmarks, QA paths, agent behavior, performance, or unclear proof loops, load harnesses/shared/references/verification-system-first.md and name the claim, falsifier, driver, grader, evidence packet, and cadence before edits.

Docs → tests → code

Write the documentation first: what will be true when this works (README section, doc comment, API doc — whatever the repo's convention is). Then failing tests that encode it. Then code to green. After green, loop back and sync all three — docs, tests, and code must agree at the end, not just the start. Work on a feature branch; never commit to the default branch.

Lenses, when judgment is contested: Ousterhout (deep modules, small interfaces), Carmack (shippability — what can be cut), Kent C. Dodds (test what users do, not implementation), Uncle Bob (leave it cleaner than found).

Deviations

The plan will be wrong somewhere — live code always holds unknowns the shape didn't map. When an edge case forces an off-plan choice that doesn't break the shape itself: pick the conservative option, log it in a Deviations section of the plan artifact (site, what forced it, what you chose), and keep going. If the deviation invalidates the shape, that's the re-shaping stop (Gotchas), not a ledger entry.

The ledger is routed, not private notes: reviewers get the deviation sites as risk coordinates (locations, never your justifications — that stays the reasoning-trail rule), /qa drives them as the edges most plausibly broken, and each entry is a discovered unknown that feeds the shape or backlog after landing.

QA the live thing

"Tests pass" is not verification. Run the application and drive the surface that changed — /qa routes by app shape (browser, API, CLI, library, MCP). Run it through the verification harness you located or built in Context first. Leave an evidence packet — screenshots, transcripts, request/response pairs, a verdict — where the repo keeps its receipts, so the claim is checkable after you're gone.

Refactor at three altitudes

With working code in hand, ask at each level — and act on what you find. When the refactor must prove it changed nothing observable and the target has no characterization tests, "unit tests pass" cannot see the seam a lift most often breaks — reach for the live-diff pattern in harnesses/shared/references/verification-system-first.md (diff the local branch against the deployed/pre-refactor build over the same backing store).

1. The diff. Would we write it this way from scratch? Duplicate code to DRY out? Conditionals to collapse? Slop to delete (unnecessary comments, defensive try/catch, casts, dead branches)?
2. The codebase. Is there a cleaner seam? Does this change reveal an abstraction that should exist — or one that should die?
3. The backlog. Does what you learned change what the product should do next? File tickets for the bigger moves; don't smuggle them into this branch.

For non-trivial code, add the synced thermo-nuclear-code-quality-review skill (skills/.external/cursor-thermo-nuclear-code-quality-review/SKILL.md) as the harsh maintainability pass before declaring the diff clean. Use julius-caveman for compressed progress/review synthesis when the evidence is long; keep code, commits, PR text, and irreversible warnings normal.

Land it

• Semantic conventional commits, push (the /yeet discipline: classify, split by concern, why-shaped bodies).
• Review by diverse providers — never only yourself. /code-review fans out fresh-context reviewers across model families; fix blockers, re-review until clean. Iterate until CI is green and rigorous — if the gate wouldn't have caught the likely failure, strengthening it is part of this ticket (/ci). Respond to every review finding: fix, ticket, or rejected with a stated reason.
• Think adversarially before shipping. If this breaks in production, what breaks first? How would we know — which log line, metric, or alert? If the answer is "we wouldn't," add the logging/alerting now, not after the incident. Dependency upgrades ride as one curated, risk-assessed commit — never a pile of unexamined bumps.
• Default stop: merge-ready. Squash-merge to master (the /ship trailer canon, meta/CONTRACTS.md) only when the operator asked for shipped, not just delivered. Then monitor if the repo has a post-ship signal, and ta-da.

Done means

State plainly: what behavior changed and how you verified it live (exact command/route/surface), what review found and how it was resolved, the deviation ledger (or "none"), what residual risk remains, and final git status --short + branch/remote state. A clean tree is part of done — every leftover path gets committed, ignored, moved out, or named as a blocker. No green-gate hand-waving: name the evidence, not the aggregate. If the work produced a reusable repo-technical lesson, offer /compound before the evidence goes stale.

Gotchas

• Skipping shape. No oracle → no delivery. Write one or route to /shape.
• Re-shaping mid-build. If implementation reveals the shape is wrong, stop and say so — don't spin on a broken spec.
• Self-review leniency. The author's context rationalizes the author's choices. Reviewers get the diff and the oracle, never your reasoning trail.
• Stale tickets. If the item already shipped (closure trailer in history, _done/ copy), refuse and fix the backlog instead.
• Heavy/parallel lanes route to /sprites; quick exploration stays local. Don't pre-shred work into atomic tasks — an outcome-shaped lane owns its own decomposition.
