* feat: implement Claude Code GitHub Action v1.0 with auto-detection and slash commands
Major features:
- Mode auto-detection based on GitHub event type
- Unified prompt field replacing override_prompt and direct_prompt
- Slash command system with pre-built commands
- Full backward compatibility with v0.x
Key changes:
- Add mode detector for automatic mode selection
- Implement slash command loader with YAML frontmatter support
- Update action.yml with new prompt input
- Create pre-built slash commands for common tasks
- Update all tests for v1.0 compatibility
Breaking changes (with compatibility):
- Mode input now optional (auto-detected)
- override_prompt deprecated (use prompt)
- direct_prompt deprecated (use prompt)
* test + formatting fixes
* feat: simplify to two modes (tag and agent) for v1.0
BREAKING CHANGES:
- Remove review mode entirely - now handled via slash commands in agent mode
- Remove all deprecated backward compatibility fields (mode, anthropic_model, override_prompt, direct_prompt)
- Simplify mode detection: prompt overrides everything, then @claude mentions trigger tag mode, default is agent mode
- Remove slash command resolution from GitHub Action - Claude Code handles natively
- Remove variable substitution - prompts passed through as-is
Architecture changes:
- Only two modes now: tag (for @claude mentions) and agent (everything else)
- Agent mode is the default for all events including PRs
- Users configure behavior via prompts/slash commands (e.g. /review)
- GitHub Action is now a thin wrapper that passes prompts to Claude Code
- Mode names changed: 'experimental-review' → removed entirely
This aligns with the philosophy that the GitHub Action should do minimal work and delegate to Claude Code for all intelligent behavior.
* fix: address PR review comments for v1.0 simplification
- Remove duplicate prompt field spread (line 160)
- Remove async from generatePrompt since slash commands are handled by Claude Code
- Add detailed comment explaining why prompt → agent mode logic
- Remove entire slash-commands loader and directories as Claude Code handles natively
- Simplify prompt generation to just pass through to Claude Code
These changes align with v1.0 philosophy: GitHub Action is a thin wrapper
that delegates everything to Claude Code for native handling.
* chore: remove unused js-yaml dependencies
These were added for slash-command YAML parsing but are no longer
needed since we removed slash-command preprocessing entirely
* fix: remove experimental-review mode reference from MCP config
The inline comment server configuration was checking for deprecated
'mode' field. Since review mode is removed in v1.0, this conditional
block is no longer needed.
* prettify
* feat: add claudeArgs input for direct CLI argument passing
- Add claude_args input to both action.yml files
- Implement shell-style argument parsing with quote handling
- Pass arguments directly to Claude CLI for maximum flexibility
- Add comprehensive tests for argument parsing
- Log custom arguments for debugging
Users can now pass any Claude CLI arguments directly:
claude_args: '--max-turns 3 --mcp-config /path/to/config.json'
This provides power users full control over Claude's behavior without
waiting for specific inputs to be added to the action.
* refactor: use industry-standard shell-quote for argument parsing
- Replace custom parseShellArgs with battle-tested shell-quote package
- Simplify code by removing unnecessary -p filtering (Claude handles it)
- Update tests to use shell-quote directly
- Add example workflow showing claude_args usage
This provides more robust argument parsing while reducing code complexity.
* bun format
* feat: add claudeArgs input for direct CLI argument passing
- Add claude_args input to action.yml for flexible CLI control
- Parse arguments with industry-standard shell-quote library
- Maintain proper argument order: -p [claudeArgs] [legacy] [BASE_ARGS]
- Keep tag mode defaults (needed for functionality)
- Agent mode has no defaults (full user control)
- Add comprehensive tests for new functionality
- Add example workflow showing usage
* format
* refactor: complete v1.0 simplification by removing all legacy inputs
- Remove all backward compatibility for v1.0 simplification
- Remove 10 legacy inputs from base-action/action.yml
- Remove 9 legacy inputs from main action.yml
- Simplify ClaudeOptions type to just timeoutMinutes and claudeArgs
- Remove all legacy option handling from prepareRunConfig
- Update tests to remove references to deleted fields
- Remove obsolete test file github/context.test.ts
- Clean up types to remove customInstructions, allowedTools, disallowedTools
Users now use claudeArgs exclusively for CLI control.
* fix: update MCP server tests after removing additionalPermissions
- Change github_ci server logic to check for workflow token presence
- Update test names to reflect new behavior
- Fix test that was incorrectly setting workflow token
* model version update
* Update package json
* remove deprecated workflow file (tests features we no longer support)
* Simplify agent mode and re-add additional_permissions input
- Agent mode now only triggers when explicit prompt is provided
- Removed automatic triggering for workflow_dispatch/schedule without prompt
- Re-added additional_permissions input for requesting GitHub permissions
- Fixed TypeScript types for mock context helpers to properly handle partial inputs
- Updated documentation to reflect simplified mode behavior
* Fix MCP config not being passed to Claude CLI
The MCP servers (including github_comment server) were configured but not passed to Claude. This caused the "update_claude_comment" tool to be unavailable.
Changes:
- Write MCP config to a file at $RUNNER_TEMP/claude-mcp-config.json
- Add mcp_config_file output from prepare.ts
- Pass MCP config file via --mcp-config flag in claude_args
- Use fs/promises writeFile to match codebase conventions
* Fix MCP tool availability and shell escaping in tag mode
Pass MCP config and allowed tools through claude_args to ensure tools like
mcp__github_comment__update_claude_comment are properly available to Claude CLI.
Key changes:
- Tag mode outputs claude_args with MCP config (as JSON string) and allowed tools
- Fixed shell escaping vulnerability when JSON contains single quotes
- Agent mode passes through user-provided claude_args unchanged
- Re-added mcp_config input for users to provide custom MCP servers
- Cleaned up misleading comments and unused file operations
- Clarified test workflow is for fork testing
Security fix: Properly escape single quotes in MCP config JSON to prevent
shell injection vulnerabilities.

- Let Claude handle config merging natively through multiple flags
- Fix TypeScript errors in test file
This approach is cleaner and relies on Claude's built-in support for multiple --mcp-config flags instead of manual JSON merging.
* feat: Copy project subagents to Claude runtime environment
Enables custom subagents defined in .claude/agents/ to work in GitHub Actions by:
- Checking for project agents in GITHUB_WORKSPACE/.claude/agents/
- Creating ~/.claude/agents/ directory if needed
- Copying all .md agent files to Claude's runtime location
- Following same pattern as slash commands for consistency
Includes comprehensive test coverage for the new functionality.

- .github/workflows/auto-fix-ci-inline.yml
- slash-commands/fix-ci.md
- .claude/commands/fix-ci.md
The workflow_run event support remains as it's useful for general automation.
* feat: Expose GitHub token as action output for external use
This allows workflows to use the Claude App token obtained by the action
for posting comments as claude[bot] instead of github-actions[bot].
Changes:
- Add github_token output to action.yml
- Export token from prepare.ts after authentication
- Allows workflows to use the same token Claude uses internally
* Debug: Add logging and always output github_token in prepare step
* Fix: Add git authentication to agent mode
Agent mode now fetches the authenticated user (claude[bot] when using Claude App token)
and configures git identity properly, matching the behavior of tag mode.
This fixes the issue where commits in agent mode were failing due to missing git identity.
* minor bun format
* remove unnecessary file
* fix: Add branch environment variable support to agent mode for signed commits
- Read CLAUDE_BRANCH and BASE_BRANCH env vars in agent mode

- This allows both tag mode and agent mode to use the same function
- Removes code duplication and ensures consistent git configuration
* feat: Improve error message for 403 permission errors when committing
When the github_file_ops MCP server gets a 403 error, it now shows a cleaner
message suggesting to rebase from main/master branch to fix the issue.

* refactor: Remove timeout_minutes parameter from action (#482)
This change removes the custom timeout_minutes parameter from the action in favor of using GitHub Actions' native timeout-minutes feature.
Changes:
- Removed timeout_minutes input from action.yml and base-action/action.yml
- Removed all timeout handling logic from base-action/src/run-claude.ts
- Updated base-action/src/index.ts to remove timeoutMinutes parameter
- Removed timeout-related tests from base-action/test/run-claude.test.ts
- Removed timeout_minutes from all example workflow files (19 files)
Rationale:
- Simplifies the codebase by removing custom timeout logic

* refactor: Remove unused slash commands and agents copying logic
Removes experimental file copying features that had no default content:
- Removed experimental_slash_commands_dir parameter and related logic
- Removed automatic project agents copying from .claude/agents/
- Eliminated flaky error-prone cp operations with stderr suppression
- Removed 175 lines of unused code and associated tests
These features were infrastructure without default content that used
problematic error handling patterns (2>/dev/null || true) which could
hide real filesystem errors.

Currently when running the `gh` command in the action, there is an error in the action logs that suggests that the GH_TOKEN isn't being set. We've solved this internally in our company by providing the GH_TOKEN in the action.
When running tests locally, process.env.RUNNER_TEMP is undefined, causing
the code to literally create "undefined/claude-prompts/" directories in
the working directory. Added fallback to "/tmp" following the pattern

* fix: prevent duplicate function signatures in review mode suggestions
This fixes a critical bug in the experimental review mode where GitHub
suggestions could create duplicate function signatures when applied.
The issue occurred because:
- GitHub suggestions REPLACE the entire selected line range
- Claude wasn't aware of this behavior and would include the function
signature in multi-line suggestions, causing duplication
Changes:
- Added detailed instructions about GitHub's line replacement behavior
- Provided clear examples for single-line vs multi-line suggestions
- Added explicit warnings about common mistakes (duplicate signatures)
- Improved code readability by using a codeBlock variable instead of
escaped backticks in template strings
This ensures Claude creates syntactically correct suggestions that
won't break code when applied through GitHub's suggestion feature.

- Uses override_prompt or direct_prompt if available, falls back to minimal prompt
- Fixes 'Prompt file does not exist' error for workflow_dispatch and schedule events
- Add TODO comment to refactor this to use createPrompt in the future
Fixes#403
Allows modes to provide custom system prompts that are appended to Claude's base system prompt. This enables mode-specific instructions without modifying the core action logic.
- Add optional getSystemPrompt method to Mode interface
- Implement method in all existing modes (tag, agent, review)
- Update prepare.ts to call getSystemPrompt and export as env var
- Wire up APPEND_SYSTEM_PROMPT in action.yml to pass to base-action
All modes currently return undefined (no additional prompts), but the infrastructure is now in place for future modes to provide custom instructions.

- Remove duplicate claude-review-mode.yml workflow
- Add synchronize event to review PR updates
- Update permissions for review mode (remove id-token, add pull-requests/issues write)
* feat: enhance review mode to provide detailed tracking comment summary
- Update review mode prompt to explicitly request detailed summaries
- Include issue counts, key findings, and recommendations in tracking comment
- Ensure users can see complete review overview without checking each inline comment
* Revert "refactor: consolidate review workflows and use review mode"
This reverts commit 54ca9485992b394e00734f4e4cfd2e62b377f9d1.
* fix: address PR review feedback for review mode
- Make generatePrompt required in Mode interface
- Implement generatePrompt in all modes (tag, agent, review)
- Remove unnecessary git/branch operations from review mode
- Restrict review mode triggers to specific PR actions
- Fix type safety issues by removing any types
- Update tests to support new Mode interface
* test: update mode registry tests to include review mode
* chore: run prettier formatting
* fix: make mode parameter required in generatePrompt function
Remove optional mode parameter since the function throws an error when mode is not provided. This makes the type signature consistent with the actual behavior.
* fix: remove last any type and update README with review mode
- Remove any type cast in review mode by using isPullRequestEvent type guard
- Add review mode documentation to README execution modes section
- Update mode parameter description in README configuration table
* mandatory bun format
* fix: improve review mode GitHub suggestion format instructions
- Add clear guidance on GitHub's suggestion block format
- Emphasize that suggestions must only replace the specific commented lines
- Add examples of correct vs incorrect suggestion formatting
- Clarify when to use multi-line comments with startLine and line parameters
- Guide on handling complex changes that require multiple modifications
This should resolve issues where suggestions aren't directly committable.
* Add missing MCP tools for experimental-review mode based on test requirements
* chore: format code
* docs: add experimental-review mode documentation with clear warnings
* docs: remove emojis from experimental-review mode documentation
* docs: clarify experimental-review mode triggers - depends on workflow configuration
* minor format update
* test: fix registry tests for experimental-review mode name change
* refactor: clean up review mode implementation based on feedback
- Remove unused parameters from generatePrompt in agent and review modes
- Keep Claude comment requirement for review mode (tracking comment)
- Add overridePrompt support to review mode
- Remove non-existent MCP tools from review mode allowed list
- Fix unused import in agent mode
These changes address all review feedback while maintaining clean code
and proper functionality.
* fix: remove redundant update_claude_comment from review mode allowed tools
The github_comment server is always included automatically, so we don't
need to explicitly list mcp__github_comment__update_claude_comment in
the allowed tools.
* feat: review mode now uses review body instead of tracking comment
- Remove tracking comment creation from review mode
- Update prompt to instruct Claude to write comprehensive review in body
- Remove comment ID requirement for review mode
- The review submission body now serves as the main review content
This makes review mode cleaner with one less comment on the PR. The
review body contains all the information that would have been in the
tracking comment.
* add back id-token: write for example
* Add PR number for context + make it mandatory to have a PR associated
* add `mcp__github__add_issue_comment` tool
* rename token
* bun format

Update add_pull_request_review_comment_to_pending_review to add_comment_to_pending_review
following upstream change in github/github-mcp-server#697
- Update .github/workflows/claude-review.yml
- Update examples/claude-auto-review.yml
In the previous commit (e07ea013bd), the GITHUB_HOST variable was placed after the image name in the Docker run command, which caused a runtime error. This commit moves the -e option before the image name so it is correctly passed into the container.
* feat: add agent mode for automation scenarios
- Add agent mode that always triggers without checking for mentions
- Implement Mode interface with support for mode-specific tool configuration
- Add getAllowedTools() and getDisallowedTools() methods to Mode interface
- Simplify tests by combining related test cases
- Update documentation and examples to include agent mode
- Fix TypeScript imports to prevent circular dependencies
Agent mode is designed for automation and workflow_dispatch scenarios
where Claude should always run without requiring trigger phrases.

* minor formatting issue
* Update to say beta instead of main
* Fix missed tracking comment to be false
* add schedule & workflow dispatch paths. Also make prepare logic conditional
* tests
* Add test workflow for workflow_dispatch functionality
* Update workflow to use correct branch reference

* minor lint update
* update workflow dispatch agent example
* minor lint update
* refactor: simplify prepare logic with mode-specific implementations
* ensure tag mode can't work with workflow dispatch and schedule tasks
* simplify: remove workflow_dispatch/schedule from create-prompt
- Remove workflow_dispatch and schedule event handling from create-prompt
since agent mode doesn't use the standard prompt generation flow
- Enforce mode compatibility at selection time in the registry instead
of runtime validation in tag mode
- Add explanatory comment in agent mode about why prompt file is needed
- Update tests to reflect simplified event handling
This reduces code duplication and makes the separation between tag mode
(entity-based events) and agent mode (automation events) clearer.
* simplify PR by making agent mode only work with workflow dispatch and schedule events
* remove unnecessary changes
* remove unnecessary changes from PR
- Revert update-comment-link.ts changes (agent mode doesn't use this)
- Revert create-initial.ts changes (agent mode doesn't create comments)
- Remove unused default-branch.ts file
- Revert install-mcp-server.ts changes (agent mode uses minimal MCP)
These files are only used by tag mode for entity-based events, not needed
for workflow_dispatch/schedule support via agent mode.
* fix: handle optional entityNumber for TypeScript
- Add runtime checks in files that require entityNumber
- These files are only used by tag mode which always has entityNumber
- Agent mode (workflow_dispatch/schedule) doesn't use these files
* linting update
* refactor: implement discriminated unions for GitHub contexts
Split ParsedGitHubContext into entity-specific and automation contexts:
- ParsedGitHubContext: For entity events (issues/PRs) with required entityNumber and isPR
- AutomationContext: For workflow_dispatch/schedule events without entity fields
- GitHubContext: Union type for all contexts
This eliminates ~20 null checks throughout the codebase and provides better type safety.
Entity-specific code paths are now guaranteed to have the required fields.

* update comment
* More robust type checking
* refactor: improve discriminated union implementation based on review feedback
- Use eventName checks instead of 'in' operator for more robust type guards
- Remove unnecessary type assertions - TypeScript's control flow analysis works correctly
- Remove redundant runtime checks for entityNumber and isPR
- Simplify code by using context directly after type guard

* some structural simplification
* refactor: further simplify discriminated union implementation
- Add event name constants to reduce duplication
- Derive EntityEventName and AutomationEventName types from constants
- Use isAutomationContext consistently in agent mode and registry
- Simplify parseGitHubContext by removing redundant type assertions
- Extract payload casts to variables for cleaner code
