Source: Issue #812

Automated Status Summary

Scope

After merging PR #103 (multi-agent routing infrastructure), we need to:

Context for Agent

Design Decisions & Constraints

• 4. Clean up comment patterns to avoid a mix of old UI-agent and new CLI-agent comments
• The keepalive loop now:
• | <!-- keepalive-loop-summary --> | github-actions[bot] | NEW: CLI agent iteration tracking | ✅ Keep for CLI agents |
• | <!-- keepalive-state:v1 --> | agents-workflows-bot[bot] | State tracking | ⚠️ Multiple copies accumulate |
• | <!-- keepalive-round: N --> | stranske | OLD: Instruction comment | ❌ CLI agents dont need this |
• The goal: For CLI agents (agent:* label), we should have exactly one updating comment (<!-- keepalive-loop-summary -->) instead of accumulating 10+ comments per PR.
• Requires PR #103 to be merged first
• This round you MUST:
• Review the Scope/Tasks/Acceptance below, identify the next incomplete task that requires code, implement it, then post a reply comment with the completed items using their exact original text.
• | Keepalive | ✅ enabled |

• After merging PR #103 (multi-agent routing infrastructure), we need to:
• 3. Mark a task checkbox complete ONLY after verifying the implementation works.

Tasks

• 1. Validate the CLI agent pipeline works end-to-end with the new task-focused prompts
• 2. Add GITHUB_STEP_SUMMARY output so iteration results are visible in the Actions UI
• 3. Streamline the Automated Status Summary to reduce clutter when using CLI agents
• 4. Clean up comment patterns to avoid a mix of old UI-agent and new CLI-agent comments

Acceptance criteria

• CLI agent receives explicit tasks in prompt and works on them
• Iteration results visible in Actions workflow run summary
• PR body shows checkboxes but not workflow clutter when using CLI agents
• UI Codex path (no agent label) continues to show full status summary
• CLI agent PRs have ≤3 bot comments total (summary, one per iteration update) instead of 10+
• State tracking is consolidated in the summary comment, not scattered

Pull request overview

This pull request fixes a bug where merge operations during conflict resolution were failing due to missing git identity configuration. The workflow was attempting to merge without configuring user.name and user.email, causing git to exit with "fatal: empty ident name not allowed", which prevented the conflict resolution workflow from functioning properly.

Changes:

• Added git identity configuration before merge operations in the "Surface merge conflicts" step
