Fix Failing Tests

Execution Flow

Task Context

Before starting execution, initialize task_context.json:

{
  "task_id": "<task_id from input>",
  "current_step": 0,
  "current_step_id": null,
  "status": "running",
  "steps": {
    "fix_loop": "pending",
    "present": "pending"
  },
  "updated_at": "<ISO timestamp>"
}

Update this file after each step completes. On error, set step status to "failed" and overall status to "failed".

Step 1: fix_loop

Type: loop Description: Run tests, analyze failures, fix source code, repeat until green

Iteration Loop

Goal: pytest exits with 0 failures (all tests pass) Max Iterations: 10

This step executes as a loop. The body steps repeat until the goal is met or max iterations reached.

Loop Body (repeats each iteration)

Body Step 1: run_tests

Type: script

Execution: Execute the following command:

cd examples/fix-loop && python3 -m pytest tests/ --tb=short 2>&1 | tail -60

Body Step 2: fix

Type: agent

Execution: Launch an independent agent with the following prompt file:

Look at the pytest failures from run_tests. Pick ONE source file that has failing tests and fix the bugs in that file.

Rules:

• Only modify files in src/, NEVER modify test files
• Fix exactly ONE file, then stop immediately
• Do NOT read or modify any other source files

Goal Evaluation

After all body steps complete, evaluate:

Goal: pytest exits with 0 failures (all tests pass)

1. If goal IS met → mark this step completed, proceed to next step.
2. If goal NOT met and iterations remain → reset body steps, start next iteration.
3. If max iterations reached → mark step completed with status "max_iterations_reached", report what remains.

Append a summary to iteration_history after each iteration.

Progress Tracking

After completing this step, update task_context.json:

• Set current_step_id to "fix_loop"
• Set steps.fix_loop to "completed"

Step 2: present

Type: inline

Execution

Follow these instructions:

Generate a markdown report summarizing the fix loop results. Include:

• Total iterations taken
• What was fixed in each iteration (file + bug description)
• Final test results
• How cascading dependencies caused failures to clear automatically Write the report to fix_report.md

Progress Tracking

After completing this step, update task_context.json:

• Set current_step_id to "present"
• Set steps.present to "completed"
