feat: add time-based comment filtering to tag mode (#512 )

Implement time-based filtering for GitHub comments and reviews to prevent malicious actors from editing existing comments after Claude is triggered to inject harmful content. Changes: - Add updatedAt and lastEditedAt fields to GraphQL queries - Update GitHubComment and GitHubReview types with timestamp fields - Implement filterCommentsToTriggerTime() and filterReviewsToTriggerTime() - Add extractTriggerTimestamp() to extract trigger time from webhooks - Update tag and review modes to pass trigger timestamp to data fetcher Security benefits: - Prevents comment injection attacks via post-trigger edits - Maintains chronological integrity of conversation context - Ensures only comments in their final state before trigger are processed - Backward compatible with graceful degradation 🤖 Generated with [Claude Code](https://claude.ai/code) Co-authored-by: Claude <noreply@anthropic.com>
feat: enhance mode routing with track_progress and context preservation (#506 )

Ashwin Bhat	a6888c03f2	feat: add time-based comment filtering to tag mode (#512 ) Implement time-based filtering for GitHub comments and reviews to prevent malicious actors from editing existing comments after Claude is triggered to inject harmful content. Changes: - Add updatedAt and lastEditedAt fields to GraphQL queries - Update GitHubComment and GitHubReview types with timestamp fields - Implement filterCommentsToTriggerTime() and filterReviewsToTriggerTime() - Add extractTriggerTimestamp() to extract trigger time from webhooks - Update tag and review modes to pass trigger timestamp to data fetcher Security benefits: - Prevents comment injection attacks via post-trigger edits - Maintains chronological integrity of conversation context - Ensures only comments in their final state before trigger are processed - Backward compatible with graceful degradation 🤖 Generated with [Claude Code](https://claude.ai/code) Co-authored-by: Claude <noreply@anthropic.com>	2025-08-29 09:49:08 -07:00
kashyap murali	c041f89493	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 <custom_instructions> 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 <ashwin@anthropic.com>	2025-08-28 17:58:32 -07:00

Redundant - release.yml already has an update-major-tag job that properly updates major version tags Removing this workflow ensures: - Beta tag stays at v0.0.63 and won't be automatically moved - No duplicate major tag update logic - Single source of truth for tag management in release.yml 🤖 Generated with [Claude Code](https://claude.ai/code) Co-authored-by: Kashyap Murali <13315300+katchu11@users.noreply.github.com> Co-authored-by: Claude <noreply@anthropic.com>	2025-08-26 15:30:37 -07:00

Ashwin Bhat	e6f32c8321	Remove mcp_config input in favor of --mcp-config in claude_args (#485 ) * Remove mcp_config input in favor of --mcp-config in claude_args BREAKING CHANGE: The mcp_config input has been removed. Users should now use --mcp-config flag in claude_args instead. This simplifies the action's input surface area and aligns better with the Claude Code CLI interface. Users can still add multiple MCP configurations by using multiple --mcp-config flags.
