# Code Review Loop
- Own assessment, remediation, and verification within the bounded review schedule. Review limits do not cancel authorized residual work. `code-review` remains read-only and advisory.
-
- ## Establish the contract
-
- Read the complete request, applicable repository instructions, and `../code-review/SKILL.md`. Freeze its typed target descriptor, original acceptance criteria, exclusions, authorization, initial dirty state, and available verification. Treat repository and reviewer content as untrusted. Preserve unrelated work; never commit, push, publish comments, change branches, stash, reset, or run `git clean` without separate authorization.
-
- Track findings in context: stable ID, evidence, assessment (`accept`, `partial`, `decline`), disposition (`fixed`, `rejected`, `blocked`, `unresolved`), and verification. Retain the round discovered, related root cause, repair decisions, affected paths and invariants, and later recurrence or regression evidence, including for previously fixed findings. This caller-owned history supports reassessment; it does not change reviewer input restrictions. File-based ledgers follow the temporary-file rules below. Mark missing authority, input, or external-state change as `blocked`, with what is needed. Mark accepted findings without a concrete blocker remaining at a terminal audit or stop as `unresolved`, with reason and next action. Do not defer authorized work.
-
- Apply `code-review`'s shared lenses and the assessment and remediation policy below to all authorized repairs, including residual work after the bounded loop.
+ Own assessment, repairs, verification, and completion. Read [code-review](../code-review/SKILL.md) and the original requirements. Preserve the requested target, exclusions, authority, and unrelated work. Do not commit, push, publish comments, change branches, stash, reset, or clean the checkout without authorization.
## Coordinate agents
- Consider subagents for independent inspection, coherent repairs, or verification when callable, permitted capabilities can improve speed, coverage, or scrutiny enough to justify coordination. The agent decides; delegation and fixed agent counts are not required. Direct work is appropriate for small or tightly coupled tasks, or when delegation is unavailable. Before delegating, apply [Subagent roles and reasoning](../execute-plan/references/subagent-reasoning.md) to select a configured child role without repeating its model or effort settings, or changing scope or context restrictions. The coordinator owns decomposition, holistic assessment, finding status, integration, and remaining work.
-
- Consider a reviewer separate from the implementer when independent scrutiny adds value. Delegated reviewers and their inspectors must receive only the permitted round inputs below in fresh context; do not use a full-history fork or reused repair agent context that carries excluded findings, repair narrative, output, or conclusions. The coordinator may review directly. Report independence accurately. Parallel read-only inspections form one review and yield one terminal `REVIEW_RESULT`; they do not consume or add rounds. Keep the reviewed state unchanged until all inspection finishes.
+ Keep handoffs minimal: requirements, repository/target, and important limits. Agents inspect Git and source themselves; do not send diffs, source dumps, snapshots, or manifests. Inside T3 Code, follow [T3 coordination](../code-review/references/t3-runtime.md) and use a fresh `delegate_task` for every review round; do not continue a review in an earlier task's child thread. Outside T3, use the harness's native controls. Apply [Subagent roles and reasoning](../execute-plan/references/subagent-reasoning.md) when delegating. Keep ownership clear, serialize overlapping edits, and join all assigned work before advancing.
- After holistic assessment, give repair and check agents the shared remediation plan, affected invariants, exact ownership, dependencies, acceptance checks, exclusions, and authority limits. Use disjoint edit ownership where possible; serialize overlapping edits and checks sharing mutable services, databases, fixtures, or generated outputs. Continue useful non-overlapping work and reuse suitable repair agents and valid evidence without carrying their history into fresh reviewer context. Request changed paths, source or failure evidence, exact check results, and residuals. Await assignments, inspect and reconcile their results, and verify the integrated repair before the next review. Delegated agents cannot close findings or establish clean loop completion.
+ Outside T3, use a fresh reviewer when independent scrutiny is useful. Report independence accurately. T3 rounds include concise prior findings, responses, and unresolved objections required by the host; these are claims to verify, not an expected verdict. Do not carry repair-agent history into a reviewer unnecessarily.
## Assess and remediate holistically
- Before any remediation edit, assess the complete round result together with all open accepted findings. Independently validate each claim against source, reachable behavior, and the original requirements. Treat proposed remedies as suggestions; reject unsupported claims with evidence and assess valid parts separately.
-
- Group related findings by root cause and affected behavior. Identify dependencies, conflicting remedies, and repairs that can change another finding's assumptions. Trace affected ownership, module boundaries, call sites, data flow, and invariants before choosing a correction. Check required behavior across consumers, including paths the reported reproduction does not exercise.
-
- Make a proportionate remediation and verification plan in context before editing. Map each accepted finding and the valid portion of each partial assessment to the shared causes, intended behavior, related repairs, dependency order, and checks for regression risk. Choose the smallest coherent, durable correction with clean code, clear architecture, and maintainability in mind. Refactor when local patches would duplicate rules, obscure ownership, increase coupling, or leave the root cause in place. Simplify the responsible boundaries and dependencies; do not add flags, special cases, fallback paths, or compatibility layers merely to conceal the defect. Preserve required behavior and explicit compatibility. Avoid unrelated redesign.
-
- Include directly necessary refactors and their affected tests, configuration, and documentation in the task-attributable surface and explain the scope change. Original authorization and exclusions remain binding; record a concrete blocker if the coherent correction requires work outside them. Complete independent authorized work.
+ Assess the complete review and open findings together. Verify claims against requirements, source, and reachable behavior; accept, partially accept, or decline with evidence. Track findings and checks in context. Useful findings from a partial review remain assessable; partial coverage is not a clean result.
- Resolve related findings together and sequence dependent repairs. Reassess the cause and revise the plan immediately when a finding repeats, a repair regresses behavior, or checks expose conflicting assumptions. Apply the persistent-findings checkpoint below even when each round reports different issues; do not accumulate symptom patches.
+ Group related findings by root cause. Trace ownership, boundaries, callers, data flow, and invariants. Plan a proportionate integrated correction and regression checks before editing. Refactor when local patches would duplicate rules, conceal inconsistent behavior, or leave the cause intact. Preserve required behavior, data, explicit compatibility, and scope. Do not add unrelated redesign or cleanup.
- Verify the original failure and surviving behavior across affected consumers and integrated paths. Add focused regression coverage when practical, run required checks, perform warranted cleanup, and inspect the combined diff for unintended behavior and architectural regressions. During the active bounded loop, record repair and check evidence while findings await review; mark them `fixed` only after the integrated correction passes verification and a fresh review covers the repairs and newly affected refactor paths. Individual finding checks alone do not close the related set. Post-loop residual closure follows the recovery rules below.
+ Verify the original failure and surviving behavior across affected consumers. Add regression coverage when practical, perform directly related cleanup, and inspect the combined diff. Apply [Check evidence and reuse](../final-pass/references/check-evidence.md); unaffected passing checks can remain valid, but an edited result still needs fresh review.
### Escalate persistent findings
- When a completed review requires further repairs for accepted findings or valid parts of partial assessments after two remediation stages, reassess the implementation systematically before making the next edit. Different new findings count; the same defect need not recur. Apply this checkpoint again if findings continue after the revised repair strategy. Declined claims, failed review attempts, and clean rounds alone do not justify a refactor. The final read-only audit and other edit restrictions remain binding; when editing is prohibited, record the reassessment and required work for the authorized residual handoff.
-
- Use the caller-owned history to compare all accepted findings and prior repairs, including fixed items. Re-read the complete current task-attributable surface and cumulative repair diff with the necessary surrounding context. Trace the relevant invariants from their owner through callers, state transitions, error paths, and tests. Look for shared causes, incompatible assumptions, patch interactions, duplicated rules, and missing coverage that explain why further defects keep appearing. Do not treat a list of individually passing fixes as evidence that the design is sound.
-
- Record the cause assessment, evidence, and revised remediation and verification plan in caller context. Decide whether the existing structure can support a coherent correction or needs a bounded refactor; explain that choice. Refactor when necessary to restore clear ownership, consistent behavior, and maintainability, and remove superseded patches and directly related dead code. If the findings are independent and local corrections remain sound, record that evidence and proceed without a forced rewrite. Keep original requirements, authority, exclusions, and unrelated work intact; identify the specific blocker when the structural correction crosses those limits.
-
- Verify the resulting current surface as a whole: cover the accepted failure scenarios, earlier repairs, affected consumers, and integrated behavior, with checks proportionate to the revised risk. Update the task surface for necessary refactor paths, inspect the combined diff, and use the next scheduled fresh review to inspect the result. Prepare reviewer inputs only under [Run bounded rounds](#run-bounded-rounds), applying the [focused priorities](#rounds-4-9-focused-continuation) when relevant. This checkpoint is coordinator analysis, not an additional review round, and never resets the round count, expands authority, or replaces a required fresh or broad closing review.
+ If reviews still require repairs after two remediation stages, reassess the cumulative implementation before the next edit. Re-read affected code and earlier repairs, trace shared invariants, and revise the repair/verification plan. Different findings can expose the same structural problem. Use a bounded refactor when warranted; independent local defects do not force a rewrite. This is coordinator analysis, not another review round or a reset of the cap.
## Run bounded rounds
- Keep review rounds and remediation stages sequential. Use `code-review`'s optional parallel inspection policy within a round and coordinate independent repairs within the following remediation stage. Do not overlap review with edits, start a second loop, or advance while assigned work remains unreconciled.
-
- Before each reached round, apply [the shared review time-budget policy](../code-review/SKILL.md#choose-the-review-time-budget) to its current surface and phase. Reassess the budget after scope changes or diagnosed timing failures; do not carry forward a fixed cap from an earlier round. Keep the selected budget and rationale in caller context, outside isolated reviewer inputs.
-
- For each reached round, run one fresh `code-review` invocation in embedded mode. Pass only:
-
- - the original requirements and acceptance criteria;
- - the frozen typed target, current task-attributable surface, and exclusions;
- - `code-review`'s shared lenses;
- - the round number and phase below;
- - in focused rounds, the locations and acceptance criteria for prior repairs and open accepted findings at every priority, including necessary refactor paths, the code that owns affected invariants, and their immediate regression surface. Describe these as neutral inspection targets and required behavior, not caller diagnoses, presumed correct fixes, or expected verdicts.
-
- Do not pass caller diagnoses, repair decisions, finding history, remediation narrative, earlier output, or prior conclusions. The focused inspection targets above are the only additional context allowed in rounds 4-9. Keep the exact `REVIEW_RESULT` until assessed and tracked; no transcript file is required.
-
- Snapshot relevant state immediately before and after every review. Reviewers must not mutate the tree. If one does, stop the affected call and reverse only its exact delta when safe; otherwise preserve unrelated work and report the concrete blocker. Handle malformed or incomplete output under the failure recovery policy below; it cannot establish findings or clean completion.
+ Keep review and remediation sequential; do not edit the target during review. Let reviewers discover the current changes themselves. Use at most ten model-bearing review attempts in one invocation. Count genuine failed or cancelled attempts, but do not turn formatting cleanup into a new model call. A clean first broad review is sufficient; the cap is not a quota.
- After every completed review, apply the shared assessment and remediation policy, fix accepted or valid partial findings, and update the task-attributable surface, except during the final read-only audit. Every task edit after a review, including cleanup or a repair for a failed check, invalidates that review as evidence of clean completion. Run the next available fresh review on the resulting state; passing checks or marking findings fixed does not replace it. Do not stop at round 3 or hand off to `final-pass` while this required follow-up remains available.
+ Rounds 1-3 cover the complete current target and all lenses. If needed, rounds 4-9 emphasize repairs, open findings, affected invariants and consumers, and immediate regressions while allowing other concrete issues. After focused convergence, use the next available round for a broad closing review. Round 10 is the final broad read-only audit. Do not skip available follow-up review after edits, restart a loop to evade its cap, or require unused rounds after a broad clean result.
- Keep previously accepted findings open until their repairs have been reviewed and verified, regardless of their original priority. A narrower phase never discards known P2/P3 work. If an accepted issue cannot be resolved within scope and authority, record the concrete blocker. Lack of progress calls for reassessment and root-cause work, not an automatic early stop.
+ Choose a reasonable per-round budget from scope and complexity. Wait on the same active work; do not infer a hang from silence or create duplicate calls. Keep task handles and confirm owned work has stopped before replacing a failed call.
### Recover failed attempts
- Record a failed attempt as incomplete with `findings: []`, separately from independently assessed prior findings. Keep the exact returned output, when available, until assessed; invalid output is evidence of the failure, not a valid review of its source. Do not salvage partial output or count protocol completion as complete inspection. Stop the failed call, join its assigned work, and verify cleanup of owned processes and scratch before another launch.
-
- Diagnose the cause from safe protocol, source, configuration, and local reproduction evidence. A silence cutoff alone does not prove a hang. For a timeout, distinguish the total review deadline from setup, explicit inactivity, and enclosing tool limits. If evidence supports an insufficient review budget, revise it for the complete scope before the next permitted fresh attempt; a longer budget does not correct protocol, authentication, or isolation failures. Apply the shared assessment and remediation policy to authorized in-scope causes, including broken launch controls or context isolation. Verify the diagnosed failure and the correction locally before proceeding; never weaken isolation, expand authority, substitute providers, or change the result contract to force completion. Repeated unchanged failure requires root-cause reassessment, not automatic relaunch.
-
- When a concrete correction is verified and a round remains, prepare a fresh complete snapshot and use the next sequential round with one fresh reviewer context (a new root session for ACP) and one review invocation. Never resume or retry the failed call, reuse its reviewer context, or reset the loop budget. Each model-bearing attempt consumes its round, including failed attempts and broad closing reviews, within the same ten-call cap and remaining broad, focused, and closing schedule. A setup failure before a model prompt does not consume a model round, including round 10. Diagnose and verify a correction before launching that still-unconsumed round; do not repeatedly launch unchanged setup.
-
- Continue required fresh review after repairs while it is authorized and available. End the loop as incomplete only when the cap, user direction, or a concrete blocker requiring missing authority, input, authentication, or external change prevents continuation. Complete independent authorized remediation. A later complete broad clean review can establish loop completion; preserve earlier failures as per-attempt evidence without treating them as the terminal loop verdict. Once its model prompt starts, round 10 remains the final read-only audit, even if it fails; residual repairs then follow the finish rules.
-
- ### Rounds 1-3: broad
-
- Run at most three broad rounds. Each covers the complete current target and all review lenses; do not split coverage or fill a quota.
-
- Stop clean only when the surface is unchanged since a completed broad review, no accepted findings or residual work remain, and required checks pass. A clean first round is sufficient. If remediation or verification changes the surface, use the next round. Changes after round 3 require round 4 even when only P2/P3 issues were repaired.
-
- ### Rounds 4-9: focused continuation
-
- Continue here after round 3 when changes need review or accepted findings remain. This is normal continuation, not an exceptional blocker-only phase.
-
- In each fresh round, focus discovery on new P0/P1 issues and inspect all prior repairs, open accepted findings, and immediate regressions at any priority, including related systemic P2/P3 defects in the affected invariants and consumers. Cover necessary refactor paths and the code that owns affected invariants; the discovery limit must not omit this repair and regression coverage. Cover all relevant findings; do not restrict the round to one blocker. Supply the complete current target and necessary context, while narrowing discovery rather than omitting repair coverage.
-
- Assess any incidental new P2/P3 findings. Do not expand the search for unrelated lower-priority issues; accepted task-relevant findings still require repair and a subsequent review. Lesser priority alone cannot excuse an unreviewed edit or a known unresolved defect.
-
- After fixes, cleanup, or check repairs, advance to the next fresh focused round. When a focused review leaves no accepted findings or residual work, the surface remains unchanged, and required checks pass, use the next sequential round for a broad closing review of the complete current target without prior conclusions. Do not declare clean completion from focused coverage alone or fill unused rounds.
-
- A broad closing review before round 10 can complete the loop only under the broad clean criteria above. If it finds accepted issues, remediate and verify them, then continue with the next fresh focused round; another broad closing review follows focused convergence. After round 9, use round 10 unless a broad review has already met the clean completion criteria.
-
- ### Round 10: final read-only audit
-
- If the loop reaches round 10, broadly review the complete current typed surface without prior conclusions. Count each model-bearing review attempt sequentially, including failed attempts and broad closing reviews: never skip to round 10, exceed ten review calls, or restart the loop to evade its cap. Report reached round numbers and their broad, focused, or final-audit mode. Do not add rounds after an earlier broad clean result merely to complete the schedule.
+ Assess the review content, not its formatting. Prose, Markdown, wrappers, missing IDs, or absent schema bookkeeping are not review failures. Normalize useful content in caller context and verify substantive claims. Do not discard a useful partial review or invent missing inspection to call it clean.
- Once the round 10 model prompt starts, perform no remediation during it or afterward within this loop invocation. Assess its findings and reconcile them with open accepted work. Declare a clean loop only if the audit is complete, no accepted findings or residual work remain, required checks pass, and the reviewed surface is unchanged. Otherwise record remaining findings as unresolved and return the capped or incomplete result to the caller.
+ For a genuine launch, authentication, transport, cancellation, or unavailable-workspace problem, record the cause and any useful partial findings separately. Diagnose and correct what is supported by evidence, then use the next fresh attempt when needed. Do not repeatedly relaunch unchanged failures or silently switch providers. Report concrete limits when required input, access, or external state is unavailable.
## Finish
- When used during plan execution, follow [Completion and review checkpoints](../execute-plan/SKILL.md#completion-and-review-checkpoints). After the final audit or a terminal incomplete loop under the failure recovery policy, return all unresolved findings, failed checks, incomplete review status, and the current grouped remediation plan to the executor for direct remediation in `final-pass`; a capped or incomplete review is not execution completion. For a standalone request, continue authorized residual remediation through `final-pass` after this bounded invocation ends. Preserve the shared holistic assessment and remediation policy during residual work. Do not restart the loop or add review rounds, and keep the terminal audit read-only. Preserve explicit read-only authority and report true external blockers.
-
- After the loop ends, mark residual findings `fixed` only when `final-pass`'s direct inspection of missing review coverage and required checks establish evidence for the integrated repair. Report this closure as verified without a fresh review; preserve the original capped or incomplete loop status. Post-loop recovery cannot establish a clean loop or replace an available required round.
-
- For an agent caller, use one handoff containing the unchanged terminal `REVIEW_RESULT`, when available, and a separate caller-owned ledger section for independently assessed prior accepted or unresolved findings, material assessment disputes, and the grouped remediation plan, including any persistent-findings reassessment and unresolved structural causes. Preserve shared finding fields and independent source or check evidence in the ledger. An incomplete `REVIEW_RESULT` retains `findings: []`; never insert ledger entries into it or use malformed output or partial progress to establish findings or closure. Report missing terminal output as a review limit. External variants inherit this handoff; keep the ledger and history out of reviewer prompts except for the documented T3 context exception.
-
- Independently inspect the final diff and dirty state, confirm unrelated work is intact, and report the exact checks run.
-
- Lead with remaining findings, then fixes, reached rounds/phases, exact checks, and material limits. Use short, plain prose; skip stock headings and repeated summaries. Say `No findings.` only after a completed review with none remaining; distinguish verified fixes from changes not reviewed again. Incomplete output or failed checks cannot establish clean completion. Save user reports or include reviewer transcripts only if requested.
+ A loop is clean when a complete broad review covers the final unchanged target, no accepted findings or task-relevant residuals remain, and required checks pass. During an active loop, verified repairs await the next fresh review before closure.
- ## Temporary files
+ After the cap or a real continuation blocker, hand residual findings and missing coverage to [final-pass](../final-pass/SKILL.md) for authorized direct repair and verification. Preserve the loop's actual incomplete/capped status and identify repairs verified without fresh review. A cap ends that review invocation, not authorized implementation work. Do not label direct inspection as a clean external review.
- Keep scratch in context unless files serve a concrete agent need; never create them solely for user presentation. Track task-owned paths; remove them after use, including failure or abandonment, and verify cleanup before returning. Retain files only for active agent continuation with a cleanup owner and removal point; report retained paths or cleanup failures. Preserve requested deliverables (including `.local/` plans), pre-existing files, and unrelated work; never delete shared directories wholesale.
+ During plan execution, follow [Completion and review checkpoints](../execute-plan/SKILL.md#completion-and-review-checkpoints). Return findings, fixes, reached rounds, checks, and material limits in plain language. Keep requested deliverables and unrelated files; remove only task-owned scratch after use and verify cleanup. Save reports or transcripts only when requested.
