#11876 or preserve premature issue framing. It treats the friction as a workflow-shape failure: full review bodies after cycle 1 create context-drain minefields.
Concept
Adopt a stricter review-loop rule:
One full PR review is fine. After that, the default must be micro-delta.
The current Cycle-N follow-up template is still too large for long-running PRs. Once a PR has received one full semantic review, later cycles should not add another large GitHub review/comment body unless a genuinely new semantic surface appears.
Empirical Trigger
PR #11876 crossed the existing review-cost circuit breaker before the latest re-review:
node ai/scripts/diagnostics/review-cost-meter.mjs 11876
Total Discussion: 34260 bytes
Formal Reviews: 3
The operator correction was explicit: repeated full reviews turn PR conversations into context-drain minefields; a future model trying to read the whole thread risks context pruning before reaching the relevant delta.
Premature implementation issue #11885 is not authority for implementation. It should be treated as an accidental early ticket and superseded by this discussion unless/until this proposal graduates.
Why #11440 Was Not Enough
Discussion #11440 correctly identified review-loop cost and introduced a circuit breaker. The current failure shows the shipped shape is still too permissive:
- The threshold fires too late for modern swarm loops.
- The Cycle-N follow-up template still encourages large public review bodies.
- CI holds and author update notes still tend to land in PR conversations instead of A2A/body edits.
- Formal review validators may force agents back into the full-template shape even when a compact micro-delta would be safer.
Proposed Rule Shape
- Cycle 1: full review template allowed and expected for semantic coverage.
- Cycle 2+: default surface is micro-delta only.
- Full-template reset: allowed only when reviewer names a new semantic surface that invalidates prior review coverage.
- CI pending/red: A2A-only or a short hold note; no full formal review body.
- Author updates: PR body edits in place; author wake/update goes through A2A, not PR comments.
- Formal state flip: when
manage_pr_review is needed, use the smallest validator-accepted body that preserves graph anchors.
Double Diamond Divergence Matrix
| Option |
When this would be right |
Evidence / falsifier |
Adoption or rejection rationale |
Residual risk |
| A. Keep current #11440 breaker |
Late-cycle bloat is rare or thresholds catch it early enough |
Falsified by #11876: 34KB / 3 formal reviews and agents still drifted toward another follow-up review |
Reject as default; the primitive exists but fires too late and too weakly |
Existing implementation remains useful precedent |
| B. Lower thresholds only |
Current micro-delta shape is right; only trigger timing is wrong |
Falsified by operator feedback: the re-review template itself is the bloat source after cycle 1 |
Partial; threshold tightening helps but does not fix public-body shape |
Could still leave validator/template pressure unresolved |
| C. One full review, then micro-delta |
Cycle 1 needs semantic coverage; later cycles mostly verify deltas or state flips |
Supported by #11876 and prior #11440/#11444 context-window damage evidence |
Recommended; preserves rigor while changing public payload shape |
Needs validator-compatible compact formal review body |
| D. No formal review bodies after cycle 1 |
PR conversations are too costly for any later formal review |
Falsifier: GitHub reviewDecision still needs explicit state flips for merge gate |
Reject; would recreate formal-state gaps |
Could be viable only with new state primitive |
Open Questions
- [OQ_RESOLUTION_PENDING] What is the exact micro-delta schema that satisfies graph ingestion without becoming another large template?
- [OQ_RESOLUTION_PENDING] Should the trigger be unconditional cycle-2+ or cycle-2+ plus minimum byte/review-count floor?
- [OQ_RESOLUTION_PENDING] Should author-side response discipline live in
pull-request or a shared review-loop payload?
- [OQ_RESOLUTION_PENDING] Does
manage_pr_review validation need a distinct micro-delta schema, or can compact metric anchors fit the existing validator safely?
- [OQ_RESOLUTION_PENDING] How should premature tickets like #11885 be dispositioned when an operator redirects to ideation?
Graduation Criteria
This discussion may graduate only after:
- A non-author peer runs
/peer-role and pressures the proposed cycle-2+ default.
- The discussion body resolves the micro-delta schema and validator strategy.
- Author-side parity is explicitly accepted, rejected, or deferred with rationale.
- Premature ticket #11885 is closed or clearly marked non-authoritative.
- A compact AC set exists that can land in one implementation ticket without rewriting the whole PR-review system.
Non-Goals
- Weakening Verify-Before-Assert.
- Removing Cycle-1 full semantic review.
- Bypassing the formal GitHub review state when it must flip.
- Using PR comments as the default update channel for late-cycle coordination.
