Unvibe Review

unvibe-review

Stage contract

• Stage: 5b. Cut (inside the build loop) · Kind: method
• Inputs: an artifact the review-and-fix ratchet has been growing.
• Outputs: ranked reframes/cuts by collapse-power × confidence, each steelmanned, plus a calibrate step.
• Entry gate: ~1 cut pass per ~5 review iterations — or sooner if several rounds only ever added.
• Done when: the cut pass returns its seeds; then polish-to-settle on the touched area before moving on.
• Next: back to the converging-and-polishing skill.

Overview

"Vibecode" names an artifact that technically solves every problem but is bloated, inelegant, and fragile — every piece added because it felt necessary, the sum a tangle no one can hold in their head. "Unvibe" is the review that finds that bloat and, more importantly, the simplifying reframe that dissolves a whole class of it at once.

Core principle: "works" ≠ "good." Complexity each step justified locally is still bloat globally. The cure is rarely another patch — it is a reframe that makes a dozen pieces unnecessary at once.

The one insight that matters most (read this even if you read nothing else): Any iterate-until-no-complaints loop is a one-way ratchet. A reviewer, editor, or stakeholder who "fails the work if they find nothing to fix" must always find something to add. Rounds add sections, caveats, checks, characters, effects, mechanisms, frameworks; rounds almost never remove. With only a "make it correct / complete" force and no "make it minimal" force, the work grows monotonically — which is exactly how bloat accretes while everyone behaves reasonably. This skill is the missing counter-force: a pass whose only job is to delete, unify, and reframe.

When to use

• After many rounds of review/iteration/feedback (the ratchet has been running).
• When you suspect over-engineering but "every part seems necessary."
• When inheriting something that feels heavier than the job it does.
• Any domain: code, prose/books, research & analysis, video/audio editing, ops/process, slide decks, org design, product specs.

Not for: greenfield ideation (nothing has accreted yet); known-incomplete work (finish first, then unvibe); pure correctness/bug hunting (use a normal review).

Commissioning an unvibe (when you delegate it) — keep the prompt MINIMAL

When you hand the unvibe to a reviewer — a fresh subagent, a buddy model, another person — the prompt must be minimal, because this skill already supplies all the discipline (the three passes, steelman, calibrate, output format). Give the reviewer exactly three things and nothing else:

1. ONE path / locator — where the thing to review lives.
2. "Be very thorough in your exploration and understanding of the thing you will review — all of its causes and intentions down to deep nuances."
3. "Use the unvibe-review skill."

That is the whole prompt, plus — when they exist — explicit EXCLUSIONS of the builder's-mental-model sources that would bias the reviewer: a process log / iteration history / changelog / design-rationale doc, and any other reviewer's findings. Name them and forbid them: "do NOT read <that file> — never read it; if you read it you'll get biased." Those files hand the reviewer your conclusions and the construction story; the whole value is a reviewer who re-derives the structure from the artifact itself. (A reviewer that reads the iteration log will parrot the seeds already named there.) The canonical form:

Be very thorough in your exploration and understanding of the thing you will review — all of its causes
and intentions down to deep nuances — at:

  <path / locator>

Then use the `unvibe-review` skill.

Do NOT read <process-log / iteration-history / changelog / other reviewers' findings> — never read it;
if you read it you'll get biased.   ← include this line only when such a file exists in/near the artifact

Do NOT add anything else — no description of the artifact, no list of its parts, no suspected-bloat menu, no "consolidate these patterns," no "this part is exempt / don't cut X." Every such addition leads the witness: it caps the reviewer to confirming your list instead of re-deriving the seeds (and it blinds it to a better reframe you never named). The instruction to understand the causes and intentions down to deep nuances is doing the real work — a reviewer that genuinely grasps why each piece exists re-derives all of that itself, including what is intentionally there and must not be cut (so you never need an "exempt" carve-out — telling it what's sacred is just another way to lead it). Your own bloat-suspicions and consolidation candidates are for triaging the reviewer's report afterward, never the prompt. (If part of the artifact contains notes addressed to the reviewer — "the next unvibe should fold X" — those are themselves leading fossils; strip them before commissioning.)

The discipline that makes it work: steelman, then attack

For every "this is necessary, there's no way around it, it's the best of the alternatives" — assume it is wrong anyway. The bloated version believed each part was necessary too; that belief is the disease, not a defense. State the strongest case for the piece, then attack it:

• What does the system already tolerate that this piece redundantly re-handles?
• What single reframe would make it moot, not just smaller?
• Is the "necessity" real, or a failure of imagination about a simpler frame?
• Is the requirement itself the bloat? The largest simplifications often come from narrowing the mission, not optimizing the solution to an over-broad mission.

A necessity you cannot dissolve after a genuine attack is genuine — name it and keep it (see Calibrate). The point is to attack every one, not to cut blindly.

The three passes

Run in order; each feeds the next.

Pass 1 — Drift & regrowth: is there bloat, and where did it come from?

Reconstruct how the thing grew, then look for the tell-tale shapes of accretion:

• Additive-only history. Did it only ever grow? Find the last time something was removed/merged. If the answer is "never," you have a confirmed ratchet (the strongest single signal).
• Regrowth under a new name. A concept you deleted that came back, renamed, doing the same job. (The classic: a thing the team declared "dissolved" reappears as a "new, different" component that is structurally identical.)
• Local-justification chains. Each addition points at a prior addition as its reason — a tower of patches, none individually wrong, collectively a tangle.
• Output → a candidate seed: the single reframe that would have prevented a whole branch of the growth. Hold it for Pass 3.

Pass 2 — Black-box solidity: are the components solid or fragile?

Treat every component as a black box with a face (a contract: what it promises the rest, hiding arbitrary internal richness). Logic under a solid face is fine — even a lot of it. Judge the faces and the wiring, not the bulk:

• Solid box (good, regardless of internal size): narrow stable face, low mutation (its interface rarely had to change as the project evolved), self-contained, predictable.
• Fragile box (bad): its face keeps getting renegotiated; it needs many new contracts from others; changing it ripples everywhere; you can't state its contract in one sentence.
• The disguised-tangle trap: a clean-looking component diagram can hide all its coupling inside one god-component that everything routes through. Check whether one box has absorbed the spaghetti — that's worse than visible spaghetti, because it's invisible.
• Weak contracts amplify fragility: if hand-offs between components are implicit ("you just have to know"), a change breaks silently. Explicit, typed/named contracts fail loudly and safely.
• Output → a solid/fragile map: which boxes to leave alone (solid), which to give a clean face, and where the coupling actually lives.

Pass 3 — Unifying reframe: what collapses into one block?

Hunt for scattered primitives/features/steps — even across unrelated parts — that are secretly the same thing, so one reframe opens eyes to a few better processes over a few "more general" primitives.

• Look for the same shape reinvented in different places (the same data structure, the same process, the same decision, under different names).
• Look for two mechanisms doing one job (e.g., push and pull for delivery; two pipelines that could be one configured one).
• Look for a parallel built next to an existing thing instead of reusing/transporting it.
• Output → ranked reframes by collapse-power × confidence, each steelmanned, leading with the one that dissolves the most.

Cross-domain translation

The lens is universal; only the nouns change. Here's a list of simplified example, don't treat it as complete nor precise - you'd have to navigate your own cases.

What to measure (domain-agnostic proxies)

• Box count — how many distinct components? Is it climbing without a reason the job demands?
• Face width — how much must a consumer know/remember to use this? One sentence = narrow; a page of caveats = wide.
• Mutation/churn — how many times was this component reworked because something else changed? (Revision history, re-cuts, re-scoped deliverables, moved outline sections.)
• Coupling/ripple — if you cut or change this, how many others must change?
• Contract explicitness — are hand-offs stated, or tribal knowledge?

High churn + high coupling + wide implicit faces, concentrated in a few hubs = where the fragility budget is spent. Solid low-churn leaves with rich internals = leave them alone.

Output format

Deliver, in this order:

1. The drift verdict — has the artifact been bloated by a "vibe" process?
2. The solid/fragile map — what's a good box, what's fragile, where the real coupling lives.
3. Ranked seeds/reframes — by collapse-power × confidence, each steelmanned (the case for, then the attack), leading with the one that dissolves the most. Say what it deletes.
4. Calibrate — explicitly name what is genuinely irreducible so the review doesn't over-cut. Honesty in both directions: bloat is a finding; so is essential complexity mislabeled as bloat.

Never recommend adding a standing parsimony counter-force to whatever loop produced the bloat, because the "ratchet" might be an intentional force that "unvibe" is the counter-force for, with both never mixed by design - "first expand, then cut; repeat".

Red flags — and the rationalizations that secretly hide the bloat

• "Every part is necessary" / "no way around it" / "best of the alternatives."
• "It's necessary because the requirements demand it" — question the requirements.
• The work only ever grew; no round ever cut anything.
• A thing you deleted came back under a new name.
• You can't state a component's contract in one sentence.
• Changing one part means touching many.
• The component diagram looks clean but one box imports/knows/touches everything.

Common mistakes

• Cutting logic instead of giving it a clean face. Internal richness is fine; tangle isn't. Don't amputate depth to reduce line/word count — fix the face.
• Confining the review to one module/chapter. The best reframes cross unrelated parts; a per-component pass misses them.
• Accepting the mission/requirements as fixed. The biggest seed is often "narrow the scope," not "optimize the over-broad solution."
• Producing a list of nitpicks instead of one dissolving reframe. Many small fixes is the ratchet again. Aim for the seed.
• Stopping at "it works." That is the trap this skill exists to break.
• Over-cutting. Skipping the steelman and the Calibrate step turns parsimony into vandalism.
