The output is a graded record, a reviewed plan, and merged work — each stage gated by something that has been watched fail. **This skill composes; it does not replace.** Each phase names the skill that owns its mechanics. Load those rather than reimplementing them: | Phase needs | Skill that owns it | |---|---| | Grade vocabulary, record shape, the `## Still open` discipline | `evidence-first-research` | | Merging lane blocks into one record | `multi-lane-report-assembly` | | Adversarially re-deriving a written record from its sources | `research-record-audit` | | Tautology / fake-honesty hunting inside a lane | `code-review-evidence` | | Mechanical per-diff gates inside a lane | `code-review-checklist` | | Blast-radius ranking of a merge | `review-changes` | | Verifying the diff base before judging it | `review-gate-diff-verification` | | Auditing a plan's acceptance gates before anyone builds | `design-gate-audit` | | Getting a human ruling per decision | `owner-gate-review` | | Per-agent isolation | `worktree-agent-isolation` | | Running one work package end to end | `task` (and `create-task-spec` when it needs a spec) | ## Phase 0 — Ground truth before anyone is dispatched Measure, do not assume. Everything the lanes are told must be something you ran. 1. **Run the project's build, test and lint commands** from its config and record the exact numbers — counts, duration, warnings. A prior note saying "two flakes" is a claim about a different machine at a different commit; re-run it. 2. **Size the codebase**: production lines by layer, test lines, ratio. Write the number down before forming an opinion about it — a suspicion recorded as a hypothesis can be disconfirmed, and one held silently cannot. 3. **Verify every claim you plan to brief the lanes with**, at `path:line`. Plan documents, prior reviews and issue bodies go stale between writing and reading; paths move, counts drift, "N unused copies" is routinely 1 used copy. 4. **Name the base commit.** Every finding is against it. Lanes citing a moving ref cite nothing. Brief the lanes with a labelled block — *"VERIFIED GROUND TRUTH (trust these over anything the brief says)"* — so a lane knows which half of its input has been checked. ## Phase 1 — Parallel expert lanes **Derive the lane roster from the repository, never from this list.** Read the project's own stacks, personas and top-level directories, and open one lane per distinct expertise the code actually demands. A fixed roster reviews the project you expected. A service with a separate front end and its own infrastructure definitions needs different lanes from a single-runtime library, and both need lanes nobody would have guessed without looking. Lanes that recur: architecture/layering, domain algorithm (retrieval, scoring, whatever the product's hard part is), the primary language's code quality, data access, test-suite QA, the consumer-facing surface (CLI, API, UI), the product's **design** — flows, states, wording — and operations/infrastructure. The surface and the design are two lanes, not one. "Is this contract correct" and "is this good to use" are different questions, and the second loses to the first whenever they share a lane. Give the design lane a way to *run* the product, and read `references/lane-brief.md` before dispatching it — a design lane briefed like a code lane returns opinions. Each lane is **read-only**, gets **its own worktree and its own workspace id**, and is told: - The verified ground truth, the base commit, and its own lens. - **The lane contract:** one `### F — [GRADE]` block per finding, grade from the closed set `MEASURED` / `READ` / `INFERRED` / `UNVERIFIED` at the end of the claim line, an `**Evidence:**` line carrying `path:line` for everything `READ` or `MEASURED`, a severity, a `## Still open` list, and its grade mix. This is `evidence-first-research`'s vocabulary; do not invent a second one. - **Permission to disagree with the brief, in writing.** Say it: *"if a briefed finding is wrong, proving it wrong is a first-class result and worth more than confirming it."* The highest-value lane output on the session this skill comes from was a lane that proved a briefed feature had never worked at all. A brief that only invites confirmation gets confirmation. - **Decision-ready owner questions**, one line each, so they can be routed without reformatting. Run lanes concurrently up to your dispatch cap; where the cap bites, wave them and give the later wave the integrated result of the earlier one to review rather than the same raw input. ## Phase 2 — Integration Follow `multi-lane-report-assembly` for the mechanics — read it before assembling, because renumbering, truncation at embedded `## ` headers and stale cross-references are where assembled records break. On top of it: - **Convergence raises confidence; lane count does not settle a fact.** Two lanes reaching the same finding independently is evidence. Two lanes disagreeing is not a vote — go read the code and settle it. The minority lane is right often enough that counting is not a method. - **Re-verify at `path:line` every finding that drives expensive work** before it enters the record. Cheap findings can ride on their lane's grade; a finding that will cost a week cannot. - Record what is **healthy**, explicitly, so a later simplification pass does not sweep it up. - Record every **disconfirmed hypothesis** as plainly as the defects. "We suspected bloat; we measured it; the suspicion was wrong" is a finding. ## Phase 3 — Adversarial verification Dispatch an independent reviewer **instructed to falsify the record**, with the sources but not your reasoning. It re-derives every load-bearing claim, re-runs every `MEASURED` one, and checks quotes verbatim at their cited lines — `research-record-audit` owns that procedure; read it when briefing this pass. Then publish what it changed, in the record, as a table: claim → refuted / corrected / softened / reproduced. A reader must be able to see which way the errors ran. On the source session this pass refuted or corrected six claims while every core conclusion survived — the failures were in supporting numbers, which is exactly what gets quoted later. **Attack before anyone implements.** A refuted number that reached a plan costs a work package. ## Phase 4 — Calibrate severity against production reality A defect that is real in code and has never once fired in a deployment is still real — and it is not a hotfix. Before ranking anything, query the live system read-only: does the table the defect writes to have any rows? Has the flag it depends on ever been set? Is the feature reachable at all in the shipped configuration? Where the live system is a managed service rather than a file you can open, "read-only" is an access decision with a cost — say which instrument you used (a direct query, telemetry, logs, a staging replica) and grade the answer accordingly. An `UNVERIFIED` calibration is a legitimate result; a calibration inferred from the code is not one at all. State the result as *loaded, not fired* when that is what it is. This changes urgency and sequencing; it must not change the finding. Two blockers on the source session had never fired in production — which made the campaign a planned release rather than a hotfix, and surfaced a sequencing constraint nobody had seen: *improving the broken filter's recall before the honest write outcome landed would have converted a dormant defect into an active one.* ## Phase 5 — Plan, then review the plan Package findings by **surface**, so everything touching one file lands in one change. Every package carries acceptance criteria **and a gate that has been watched go red**. Then put the plan through two independent reviews before implementation — an architect pass for sequencing and blast radius, and an adversarial pass that attacks the plan's own claims and its gates (`design-gate-audit` owns gate honesty; read it when auditing acceptance criteria). Fold both into a revision, and **list what the revision changed** — a plan whose corrections are invisible teaches nobody, and reviewers cannot tell a considered rejection from an overlooked one. Sequencing rules worth writing down every time: - **Name the serialisation points.** A file that five packages edit is not parallelisable, however independent the packages read. - **The measurement chain runs backwards from what you want to prove.** If package C's ranking change must be measured on a corpus, and package A changes what the corpus contains, the order is A → corpus → C. Getting this backwards is easy and invisible until the numbers are useless. - **Two packages that make each other worse in between ship as one change.** Deleting the last copy of some data in one package while another still fabricates success is strictly worse than the state you started in. **Draw the module the plan changes, before and after.** Two diagrams in the repo's own diagram convention: the current shape built from verified code facts, the proposed shape built from what the review decided. A reviewer sees a restructuring in a picture that they will not see in a finding table. Route every question that needs a human through `owner-gate-review` — one decision, one ruling, and generate its form programmatically from a decisions array rather than hand-editing the template. Where no owner is available, decide, record the decision and the reason, and mark it reversible. ## Phase 6 — Waved implementation Each package runs through `task`, in its own worktree, TDD-first, with its named gate. Waves are ordered by the sequencing rules; packages inside a wave run concurrently only where they share no serialisation point. Two hazards specific to running many lanes at once: - **A lane holding unpushed work is a lane that has stalled invisibly.** Its branch looks absent from the integration side while its worktree holds everything. Require a push after every commit, and check for unpushed commits before concluding a lane produced nothing. - **Every gate value that is a pin — a line count, a member count, a metric floor — carries a raise history on the constant.** A ratchet re-pinned silently is a ratchet that has been turned off. See the failure modes below. ## Phase 7 — Merge, and review every join Defects that exist only where two individually-correct branches meet are the ones no lane can find. On the source session at least five did. Verify the base first (`review-gate-diff-verification`, read it before judging a merged diff), then on the **merged** tree, not the branches: - Re-run the build and the full suite. A per-branch green says nothing about the join. - **Read what a mechanical conflict resolution dropped.** Taking one side wholesale silently removes anything the other side added that had no counterpart — a test, an assertion, a deliberately-changed constant. Diff each resolved file against *both* parents and account for every line that vanished. - **Check that test infrastructure still does its job.** A helper that builds a pre-migration fixture stops being able to build it the moment another branch adds a constraint it does not know to drop; the test then fails in arrange, not assert. - **Check the dispatch, not just the compile.** A method added on one side and a fake extended on the other can compile and still never be called. Your stack's extension names the concrete shape this takes. - Write the integration reasoning into the merge commit. It is the only place that survives. ## Phase 8 — Record the decisions Every conclusion that changes how the system is built becomes a decision record in whatever form the project already keeps, and each one **names what it supersedes**. A campaign this size routinely contradicts earlier decisions; a superseding record that does not say so leaves two live answers. Three rules learned by getting them wrong: - **Separate what was measured from what was not, inside one record.** A decision that deletes two things — one measured to fail, one that never ran and therefore could not be evaluated — must not let the measurement carry both. Removing unreachable code is a maintenance argument, not an efficacy one, and a record that blurs them will be quoted as if it measured both. - **Record refuted directions, not just the chosen one.** A reader who cannot see that an alternative was tested and lost will propose it again. Include your own rejected argument. - **A decision resting on a circular benchmark can be overturned mid-implementation.** When that happens, supersede rather than amend, and say which measurement changed the verdict. Note where the deleted code is recoverable from. ## The failure modes this exists to catch Each of these happened, most more than once. They are the reason for the phases above; read `references/failure-modes.md` when you hit one, or before designing a benchmark or a gate. 1. **Circular benchmark.** A filter validated on a corpus built from the shape it matches scores perfectly by construction — and a later review reuses that rigged corpus to argue the opposite. **Control, required not advised: held-out evaluation by family.** Partition the corpus by the thing that generated it (tool family, source repo, operator, document type), train or tune on some families and evaluate on the held-out ones. A number that does not survive leave-one-family-out does not ship. An in-sample 0.946 AUC is a description of the corpus. 2. **Vacuous gate.** A metrics test reporting nDCG/MRR/recall of 0 for every query while asserting only "in range [0, 1]". A test comparing a column that is 0-of-2518 populated against a stale map: *always false equals always false*. Every gate is broken on purpose once and watched go red, before it is trusted. 3. **The specification encodes the defect.** A test or `.feature` file asserts the bug as required behaviour, so the fix turns it red and the reflex is to "restore" it. **Adjudicate, in the commit message**: is the assertion the contract, or a transcription of what the code did? Four separate cases on one session; every one was the second. 4. **Join defect.** See Phase 7. 5. **In-sample numbers.** Any metric produced on the data it was tuned on. Label it, and re-derive held-out before it justifies work. 6. **The finding that is a refutation.** The mechanism is usually silent: a parameter dropped because nothing matched it, a value written to a column that does not exist. A feature can pass review, an ADR, a benchmark and a full green suite while doing nothing. Treat a RED test that refuses to go red as evidence, not as a broken test. 7. **Ratchets re-pinned without a raise history**, and **lanes stalling with unpushed work**. 8. **Derive, don't pin.** Every expectation that mirrors something else — a tool list, a hash map, a set of statements, a fixture's contents — is derived from the source of truth at test time, or it is a second source of truth that drifts silently. A hand-maintained copy is a defect with a delay fuse. ## Gotchas - **The base moves under you.** If the trunk merges during the review, the squashed result can differ from the head every lane read. Re-fetch, diff the reviewed head against the merged commit, re-run the gates on the merged state, and re-verify each finding against the merged file before accepting it. - **Never weaken a gate to make a merge green.** Six retrieval failures on the source session were genuine ranking movement on a denser corpus; they were left failing and routed to the package that owned them. A gate lowered to pass is a gate deleted. - **Characterization tests keep CI honest, not quiet.** When a finding cannot be fixed in this wave, pin the *current* behaviour with a test that names it as character … ## Source & license This open-source skill is cataloged on AgentStack and links to its original source — we do not rehost the code. - **Author:** [Arasz](https://github.com/Arasz) - **Source:** [Arasz/ai-badger](https://github.com/Arasz/ai-badger) - **License:** MIT - **Homepage:** https://github.com/Arasz/ai-badger Install and usage instructions live in the source repository linked above. ## Pricing - **Free** — Free ## Security capabilities Automated source analysis of v0.1.0 — what this tool can access: - **Network access:** no - **Filesystem access:** no - **Shell / process execution:** no - **Environment & secrets:** no - **Dynamic code execution:** no *"Yes" means the capability is present in the source — more access means more to trust, not that it is unsafe.* ## Versions - **0.1.0** — security scan: passed — Imported from the upstream source. ## Links - Listing page: https://agentstack.voostack.com/l/skill-arasz-ai-badger-complete-project-scope-code-review - Seller: https://agentstack.voostack.com/s/arasz - Browse the marketplace: https://agentstack.voostack.com/browse --- Listed on AgentStack — the marketplace for AI agent skills and MCP servers.
