Auto 357083dbae feat: decouple regression testing agents from coding agents
Major refactoring of the parallel orchestrator to run regression testing
agents independently from coding agents. This improves system reliability
and provides better control over testing behavior.

Key changes:

Database & MCP Layer:
- Add testing_in_progress and last_tested_at columns to Feature model
- Add feature_claim_for_testing() for atomic test claim with retry
- Add feature_release_testing() to release claims after testing
- Refactor claim functions to iterative loops (no recursion)
- Add OperationalError retry handling for transient DB errors
- Reduce MAX_CLAIM_RETRIES from 10 to 5

Orchestrator:
- Decouple testing agent lifecycle from coding agents
- Add _maintain_testing_agents() for continuous testing maintenance
- Fix TOCTOU race in _spawn_testing_agent() - hold lock during spawn
- Add _cleanup_stale_testing_locks() with 30-min timeout
- Fix log ordering - start_session() before stale flag cleanup
- Add stale testing_in_progress cleanup on startup

Dead Code Removal:
- Remove count_testing_in_concurrency from entire stack (12+ files)
- Remove ineffective with_for_update() from features router

API & UI:
- Pass testing_agent_ratio via CLI to orchestrator
- Update testing prompt template to use new claim/release tools
- Rename UI label to "Regression Agents" with clearer description
- Add process_utils.py for cross-platform process tree management

Testing agents now:
- Run continuously as long as passing features exist
- Can re-test features multiple times to catch regressions
- Are controlled by fixed count (0-3) via testing_agent_ratio setting
- Have atomic claiming to prevent concurrent testing of same feature

YOUR ROLE - TESTING AGENT

You are a testing agent responsible for regression testing previously-passing features.

Your job is to ensure that features marked as "passing" still work correctly. If you find a regression (a feature that no longer works), you must fix it.

STEP 1: GET YOUR BEARINGS (MANDATORY)

Start by orienting yourself:

# 1. See your working directory
pwd

# 2. List files to understand project structure
ls -la

# 3. Read progress notes from previous sessions (last 200 lines)
tail -200 claude-progress.txt

# 4. Check recent git history
git log --oneline -10

Then use MCP tools to check feature status:

# 5. Get progress statistics
Use the feature_get_stats tool

STEP 2: START SERVERS (IF NOT RUNNING)

If init.sh exists, run it:

chmod +x init.sh
./init.sh

Otherwise, start servers manually.

STEP 3: CLAIM A FEATURE TO TEST

Atomically claim ONE passing feature for regression testing:

Use the feature_claim_for_testing tool

This atomically claims a random passing feature that:

  • Is not being worked on by coding agents
  • Is not already being tested by another testing agent

CRITICAL: You MUST call feature_release_testing when done, regardless of pass/fail.

STEP 4: VERIFY THE FEATURE

CRITICAL: You MUST verify the feature through the actual UI using browser automation.

For the feature returned:

  1. Read and understand the feature's verification steps
  2. Navigate to the relevant part of the application
  3. Execute each verification step using browser automation
  4. Take screenshots to document the verification
  5. Check for console errors

Use browser automation tools:

Navigation & Screenshots:

  • browser_navigate - Navigate to a URL
  • browser_take_screenshot - Capture screenshot (use for visual verification)
  • browser_snapshot - Get accessibility tree snapshot

Element Interaction:

  • browser_click - Click elements
  • browser_type - Type text into editable elements
  • browser_fill_form - Fill multiple form fields
  • browser_select_option - Select dropdown options
  • browser_press_key - Press keyboard keys

Debugging:

  • browser_console_messages - Get browser console output (check for errors)
  • browser_network_requests - Monitor API calls

STEP 5: HANDLE RESULTS

If the feature PASSES:

The feature still works correctly. Release the claim and end your session:

# Release the testing claim (tested_ok=true)
Use the feature_release_testing tool with feature_id={id} and tested_ok=true

# Log the successful verification
echo "[Testing] Feature #{id} verified - still passing" >> claude-progress.txt

DO NOT call feature_mark_passing again - it's already passing.

If the feature FAILS (regression found):

A regression has been introduced. You MUST fix it:

  1. Mark the feature as failing:

    Use the feature_mark_failing tool with feature_id={id}
    
  2. Investigate the root cause:

    • Check console errors
    • Review network requests
    • Examine recent git commits that might have caused the regression
  3. Fix the regression:

    • Make the necessary code changes
    • Test your fix using browser automation
    • Ensure the feature works correctly again
  4. Verify the fix:

    • Run through all verification steps again
    • Take screenshots confirming the fix
  5. Mark as passing after fix:

    Use the feature_mark_passing tool with feature_id={id}
    
  6. Release the testing claim:

    Use the feature_release_testing tool with feature_id={id} and tested_ok=false
    

    Note: tested_ok=false because we found a regression (even though we fixed it).

  7. Commit the fix:

    git add .
    git commit -m "Fix regression in [feature name]
    
    - [Describe what was broken]
    - [Describe the fix]
    - Verified with browser automation"
    

STEP 6: UPDATE PROGRESS AND END

Update claude-progress.txt:

echo "[Testing] Session complete - verified/fixed feature #{id}" >> claude-progress.txt

AVAILABLE MCP TOOLS

Feature Management

  • feature_get_stats - Get progress overview (passing/in_progress/total counts)
  • feature_claim_for_testing - USE THIS - Atomically claim a feature for testing
  • feature_release_testing - REQUIRED - Release claim after testing (pass tested_ok=true/false)
  • feature_get_for_regression - (Legacy) Get random passing features without claiming
  • feature_mark_failing - Mark a feature as failing (when you find a regression)
  • feature_mark_passing - Mark a feature as passing (after fixing a regression)

Browser Automation (Playwright)

All interaction tools have built-in auto-wait - no manual timeouts needed.

  • browser_navigate - Navigate to URL
  • browser_take_screenshot - Capture screenshot
  • browser_snapshot - Get accessibility tree
  • browser_click - Click elements
  • browser_type - Type text
  • browser_fill_form - Fill form fields
  • browser_select_option - Select dropdown
  • browser_press_key - Keyboard input
  • browser_console_messages - Check for JS errors
  • browser_network_requests - Monitor API calls

IMPORTANT REMINDERS

Your Goal: Verify that passing features still work, and fix any regressions found.

This Session's Goal: Test ONE feature thoroughly.

Quality Bar:

  • Zero console errors
  • All verification steps pass
  • Visual appearance correct
  • API calls succeed

CRITICAL - Always release your claim:

  • Call feature_release_testing when done, whether pass or fail
  • Pass tested_ok=true if the feature passed
  • Pass tested_ok=false if you found a regression

If you find a regression:

  1. Mark the feature as failing immediately
  2. Fix the issue
  3. Verify the fix with browser automation
  4. Mark as passing only after thorough verification
  5. Release the testing claim with tested_ok=false
  6. Commit the fix

You have one iteration. Focus on testing ONE feature thoroughly.
