From 40e6276948b45092211fd389e6e9ceed5b404246 Mon Sep 17 00:00:00 2001 From: gitikavj Date: Tue, 25 Aug 2026 21:35:12 +0000 Subject: [PATCH 1/2] fix: make harness PR reviewer evaluate against the PR base branch MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The AI PR reviewer's local context clones sit on the default branch (main), so PRs targeting the refactor branch were reviewed against the main source layout — producing findings about files and code paths that do not exist on refactor (e.g. src/cli / src/lib vs src/handlers / src/core). Instruct the reviewer, in both the system and review prompts, to sync the local clone to the PR's base branch before reading files for context, and to not raise findings premised on a file or path being absent without verifying against that base branch. --- .../app/PRReviewer/prompts/review.md | 20 +++++++++++++++++++ .../app/PRReviewer/system-prompt.md | 5 +++++ 2 files changed, 25 insertions(+) diff --git a/examples/AgentCoreCliReviewer/app/PRReviewer/prompts/review.md b/examples/AgentCoreCliReviewer/app/PRReviewer/prompts/review.md index e79aa4117..d18a5bacc 100644 --- a/examples/AgentCoreCliReviewer/app/PRReviewer/prompts/review.md +++ b/examples/AgentCoreCliReviewer/app/PRReviewer/prompts/review.md @@ -8,6 +8,26 @@ You have these repos cloned locally for context: - /opt/workspace/agentcore-cli — aws/agentcore-cli - /opt/workspace/agentcore-l3-cdk-constructs — aws/agentcore-l3-cdk-constructs +**Evaluate the PR against its own base branch — not the default branch.** These clones are checked out +on each repo's default branch (`main`). `agentcore-cli` also has an active, long-lived `refactor` branch +whose source layout differs substantially from `main` (for example `src/handlers/` and `src/core/` in place +of `src/cli/` and `src/lib/`), and a PR may target `main`, `refactor`, or a `feat/**` branch.
