Fix Test

IMPORTANT: Start your response with a context preamble.

Call help_lookup(topic="fix-test", mode="preamble") and display the returned preamble text as a blockquote. Then tell the user they can say "tell me more" for a step-by-step guide, or answer the scoping questions below to proceed.

If the MCP call fails, fall back to:

Fix Test — Diagnoses failing tests, classifies the root cause, and applies targeted fixes automatically.

Scoping

Before running, ask:

1. Target: "Which test is failing? A specific file, test name, or should I find failures automatically?"
2. Context: "Did this start failing after a recent change, or has it been broken?"

Execution

Step 1: Identify Failures

Run the failing test(s) to capture the error:

uv run pytest <target> -v --tb=short 2>&1 | tail -40

Step 2: Diagnose Root Cause

Common failure patterns:

Pattern	Root Cause	Fix
ModuleNotFoundError	Import path changed	Update import
AttributeError: mock	Mock target wrong	Match import path
AssertionError	Expected value drift	Update assertion
TypeError: __init__	Constructor changed	Update call site
FileNotFoundError	Fixture path wrong	Use tmp_path

Step 3: Apply Fix and Re-run

Apply the fix, then re-run the test. If it still fails, diagnose again with the new error. Repeat up to 3 times.

uv run pytest <target> -v --tb=short

Step 4: Report

After fixing (or exhausting 3 attempts), report:

## Fix Test Results

**Tests Fixed:** X/Y | **Attempts Used:** Z/3

### Fixed
| Test | Root Cause | Fix Applied |
|------|------------|-------------|

### Still Failing (if any)
| Test | Error | Attempts | Notes |
|------|-------|----------|-------|

Follow-Up

After presenting results, offer:

• "Want me to generate missing tests for the fixed module?"
• "Should I check for similar failures elsewhere?"
• "Want a deeper look at the root cause?"
