From 49c50756d0d6868e7c5e247062d0ae3077b88280 Mon Sep 17 00:00:00 2001 From: fullsend-code Date: Tue, 26 May 2026 19:08:57 +0000 Subject: [PATCH 1/9] docs(#1537): clarify findings vs inline comments distinction MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The log messages in submitFormalReview() said "finding(s) omitted" when out-of-diff findings could not be posted as inline comments. This wording led agents to incorrectly conclude the findings were irrelevant to the verdict. In reality, the GitHub API cannot accept review comments on lines outside the PR diff — the findings themselves remain valid and still influence the verdict. Changes: - postreview.go: Reword log messages from "finding(s) omitted: ..." to "inline comment(s) omitted (...) — findings still count toward verdict". Add a code comment explaining the GitHub API limitation. - postreview_test.go: Update test assertions to match new messages. - pr-review/SKILL.md: Add a "Findings vs inline comments" section documenting the pipeline: findings determine the verdict; inline comments are a delivery mechanism with GitHub API constraints. Note: pre-commit could not run in sandbox (Go toolchain permission error, exit 3). TestResolveLinuxBinary_Download failed due to sandbox network restrictions (pre-existing, unrelated).

Without capturing the full prompt/completion pairs, you cannot reconstruct why an agent did what it did. The reasoning is not in the code — it is in the model interaction. This is fundamentally different from debugging traditional software where you can read the source and step through the logic. -**Distributed agency.** In a multi-agent system (see [code-review.md](code-review.md), [agent-architecture.md](agent-architecture.md)), a single PR review involves multiple independent agents — triage, intent alignment, correctness, security, injection defense — each making separate decisions that compose into an outcome. Understanding "why did this PR get approved" requires tracing across all of them. This is analogous to distributed tracing in microservices, but harder because each "service" is non-deterministic. +**Distributed agency.** In a multi-agent system (see [code-review.md](code-review.md), [agent-architecture.md](agent-architecture.md)), a single PR review involves multiple independent agents — correctness, security, intent-coherence, style-conventions, docs-currency, cross-repo-contracts — each making separate decisions that compose into an outcome.

This is analogous to distributed tracing in microservices, but harder because each "service" is non-deterministic. **Scale of activity.** A mid-to-large org may have dozens of repos with heterogeneous languages, frameworks, and deployment patterns. Agents operating across all of them generate a volume of decisions, reviews, and changes that no human can read in full. The operators need aggregated views, anomaly detection, and drill-down capabilities — not raw logs.
