Add workflow to detect invalid CI command attempts (#2037)

justin808 · claude · web-flow · commit 83f2686a0f78 · 2025-11-17T16:32:46.000-10:00
## Summary This PR adds a GitHub Actions workflow that detects when users try to use CI commands in PR comments but get the syntax wrong. It provides helpful guidance on the correct commands and available alternatives. ## Problem Users sometimes try variations like: - `/run-ci` - `/skip-ci` - `/enable-full-ci` - `/trigger-tests` These don't match our actual commands (`/run-skipped-ci`, `/stop-run-skipped-ci`), so nothing happens and users are left confused. ## Solution New workflow (`.github/workflows/detect-invalid-ci-commands.yml`) that: 1. **Detects similar commands**: Watches for slash commands containing CI-related keywords (run, skip, ci, full, trigger, enable, disable, test, etc.) 2. **Excludes valid commands**: Doesn't trigger for `/run-skipped-ci` or `/stop-run-skipped-ci` 3. **Posts helpful response**: Provides comprehensive documentation of: - All available GitHub comment commands - What each command does - Requirements and examples - Local debugging alternatives (CI scripts) 4. **Adds reaction**: Puts a 👀 emoji on the original comment so users know it was seen ## Example Response When someone comments `/run-ci`, the bot will respond with: > 👋 It looks like you may have tried to use a CI command, but it doesn't match the available commands. > > **Invalid command(s) detected:** `/run-ci` > > ## Available GitHub Comment Commands > > ### 1. `/run-skipped-ci` - Enable Full CI Mode > [Full documentation...] > > ### 2. `/stop-run-skipped-ci` - Disable Full CI Mode > [Full documentation...] > > ### 3. `@claude` - Claude Code AI Review > [Full documentation...] > > ## Local CI Debugging > [Local alternatives like `bin/ci-rerun-failures`...] ## Testing - ✅ Validated YAML syntax - ✅ Tested command detection logic with 10 test cases - ✅ Verified pattern matching for slash commands - ✅ Confirmed valid commands are excluded - ✅ Prettier and RuboCop passing ## Benefits - **Better DX**: Users get immediate, helpful feedback - **Self-service**: Reduces need to ask maintainers for help - **Documentation**: Commands are documented in the response - **Discoverability**: Users learn about local debugging tools 🤖 Generated with [Claude Code](https://claude.com/claude-code)  - - - This change is [<img src="https://reviewable.io/review_button.svg" height="34" align="absmiddle" alt="Reviewable"/>](https://reviewable.io/reviews/shakacode/react_on_rails/2037)   ## Summary by CodeRabbit * **Chores** * Added a workflow that detects potential CI-related slash commands in PR comments and posts a helpful, formatted response listing detected commands, usage tips, and debugging/local CI guidance. * Updated CI trigger behavior to run all workflows when no skipped checks are found, simplified status and comment messaging, and improved progress/label reporting.  --------- Co-authored-by: Claude <noreply@anthropic.com>

+
+            ## Available GitHub Comment Commands
+
+            ### 1. \\\`/run-skipped-ci\\\` - Enable Full CI Mode
+            Triggers all CI workflows that were skipped due to unchanged code.
+
+            **What it does:**
+            - Runs tests across all supported versions (Ruby 3.2-3.4, Node 20-22, Shakapacker 8-9, React 18-19)
+            - Adds the \\\`full-ci\\\` label to persist full testing on future commits
+            - Triggers: Main tests, Generator tests, and React on Rails Pro tests
+
+            **Requirements:**
+            - Must have write access to the repository
+            - Use at the start of a comment or after a newline
+
+            **Example:**
+            \\\`\\\`\\\`
+            /run-skipped-ci
+            \\\`\\\`\\\`
+
+            ---
+
+            ### 2. \\\`/stop-run-skipped-ci\\\` - Disable Full CI Mode
+            Returns to standard CI behavior (optimized suite, skips tests for unchanged code).
+
+            **What it does:**
+            - Removes the \\\`full-ci\\\` label from the PR
+            - Future commits will use the fast feedback CI suite
+            - Does NOT stop currently running workflows
+
+            **Requirements:**
+            - Must have write access to the repository
+
+            **Example:**
+            \\\`\\\`\\\`
+            /stop-run-skipped-ci
+            \\\`\\\`\\\`
+
+            ---
+
+            ### 3. \\\`@claude\\\` - Claude Code AI Review
+            Invokes Claude Code AI to perform code review or answer questions.
+
+            **What it does:**
+            - Analyzes code changes and provides feedback
+            - Follows instructions specified in the comment
+            - Can read CI results on PRs
+
+            **Example:**
+            \\\`\\\`\\\`
+            @claude please review the error handling in this PR
+            \\\`\\\`\\\`

+
+            ## Local CI Debugging
+
+            Instead of using comment commands, you can replicate CI failures locally:
+
+            **Check CI status:**
+            \\\`\\\`\\\`bash
+            gh pr view --json statusCheckRollup
+            \\\`\\\`\\\`
+
+            **Re-run only failed jobs:**
+            \\\`\\\`\\\`bash
+            bin/ci-rerun-failures
+            \\\`\\\`\\\`
+
+            **Run specific failed specs:**
+            \\\`\\\`\\\`bash
+            pbpaste | bin/ci-run-failed-specs  # macOS
+            \\\`\\\`\\\`
+
+            **Switch between CI configurations:**
+            \\\`\\\`\\\`bash
+            bin/ci-switch-config minimum  # Test with Ruby 3.2, Node 20, etc.
+            bin/ci-switch-config latest   # Return to Ruby 3.4, Node 22, etc.
+            \\\`\\\`\\\`
