Refine Test Plan

Update it_{current_iteration}_test-plan.md in place. The file already exists and is provided in context.

Do NOT implement code. Only revise the test plan document.

Two modes available — determined by the mode context variable:

• Editor mode (default): apply user-requested updates to the plan.
• Challenger mode (mode = "challenger"): run an adversarial review of the plan and challenge weak coverage, assertions, and missing cases before applying any edits.

Inputs

| Source | Used for | |--------|----------| | test_plan_file | Current plan file name | | test_plan_content | Existing test plan content | | User responses | Clarifications and approval of proposed edits |

Editor Mode

Ask only what is needed, then update the document directly.

Focus on:

• Preserve the existing section structure, headings, and overall organization unless the user explicitly requests structural changes
• Test scope completeness
• Acceptance criteria traceability
• Execution order and environment assumptions
• Clarity and actionability of assertions

Challenger Mode

Act as an independent reviewer trying to break the plan.

Evaluate at minimum:

1. Coverage gaps for each acceptance criterion
2. Missing negative/error-path scenarios
3. Weak or non-verifiable assertions
4. Ambiguous setup/fixtures/test data
5. Over-reliance on manual testing where automation should be used
6. Missing quality checks (typecheck, lint, CI gates) where applicable

Present findings one at a time:

Challenge [N/total]: <area>

Finding: <specific weakness>
Risk: <why this can fail in practice>
Suggestion: <concrete improvement>

Accept / Reject / Discuss?

Only apply accepted suggestions to the document after all findings are triaged.
