From c041f894935e23b9badcd6de3f8fe3dfb4d9069d Mon Sep 17 00:00:00 2001 From: kashyap murali Date: Thu, 28 Aug 2025 17:58:32 -0700 Subject: [PATCH] feat: enhance mode routing with track_progress and context preservation (#506) * feat: enhance mode routing with track_progress and context preservation This PR implements enhanced mode routing to address two critical v1 migration issues: 1. Lost GitHub context when using custom prompts in tag mode 2. Missing tracking comments for automatic PR reviews Changes: - Add track_progress input to force tag mode with tracking comments for PR/issue events - Support custom prompt injection in tag mode via section - Inject GitHub context as environment variables in agent mode - Validate track_progress usage (only allowed for PR/issue events) - Comprehensive test coverage for new routing logic Event Routing: - Comment events: Default to tag mode, switch to agent with explicit prompt - PR/Issue events: Default to agent mode, switch to tag mode with track_progress - Custom prompts can now be used in tag mode without losing context This ensures backward compatibility while solving context preservation and tracking visibility issues reported in discussions #490 and #491. * formatting * fix: address review comments - Simplify track_progress description to be more general - Move import to top of types.ts file * revert: keep detailed track_progress description The original description provides clarity about which specific event actions are supported. * fix: add GitHub CI MCP tools to tag mode allowed list Claude was trying to use CI status tools but they weren't in the allowed list for tag mode, causing permission errors. This fix adds the CI tools so Claude can check workflow status when reviewing PRs. * fix: provide explicit git base branch reference to prevent PR review errors - Tell Claude to use 'origin/{baseBranch}' instead of assuming 'main' - Add explicit instructions for git diff/log commands with correct base branch - Fixes 'fatal: ambiguous argument main..HEAD' error in fork environments - Claude was autonomously running git diff main..HEAD when reviewing PRs * fix prompt generation * ci pass --------- Co-authored-by: Ashwin Bhat --- action.yml | 6 + src/create-prompt/index.ts | 20 ++- src/create-prompt/types.ts | 3 + src/github/context.ts | 2 + src/modes/agent/index.ts | 43 ++++++ src/modes/detector.ts | 77 +++++++++-- src/modes/tag/index.ts | 23 +++- test/create-prompt.test.ts | 35 ++++- test/install-mcp-server.test.ts | 1 + test/mockContext.ts | 1 + test/permissions.test.ts | 1 + tests/modes/detector.test.ts | 229 ++++++++++++++++++++++++++++++++ 12 files changed, 414 insertions(+), 27 deletions(-) create mode 100644 tests/modes/detector.test.ts diff --git a/action.yml b/action.yml index 31e3fca..fa852dc 100644 --- a/action.yml +++ b/action.yml @@ -73,6 +73,10 @@ inputs: description: "Enable commit signing using GitHub's commit signature verification.
