iterative-runner
Runs Claude in a retry loop until tests pass or task completes. Use for TDD loops, overnight builds, or any task needing repeated iteration until success. Triggers on: loop until done, keep trying, retry until pass, TDD loop, iterate until tests pass.
Best use case
iterative-runner is best used when you need a repeatable AI agent workflow instead of a one-off prompt. It is especially useful for teams working in multi. Runs Claude in a retry loop until tests pass or task completes. Use for TDD loops, overnight builds, or any task needing repeated iteration until success. Triggers on: loop until done, keep trying, retry until pass, TDD loop, iterate until tests pass.
Runs Claude in a retry loop until tests pass or task completes. Use for TDD loops, overnight builds, or any task needing repeated iteration until success. Triggers on: loop until done, keep trying, retry until pass, TDD loop, iterate until tests pass.
Users should expect a more consistent workflow output, faster repeated execution, and less time spent rewriting prompts from scratch.
Practical example
Example input
Use the "iterative-runner" skill to help with this workflow task. Context: Runs Claude in a retry loop until tests pass or task completes.

# Iterative Runner Runs Claude in a persistent loop that keeps retrying until tests pass or the task is complete. ## When to Use - Running TDD loops that iterate until all tests pass - Overnight builds that need to keep trying until successful - Any task requiring repeated attempts until completion criteria are met - Automated retry for flaky or complex implementations ## Core Concept ```bash while :; do cat PROMPT.md | claude ; done ``` Keep iterating until task is complete. ## Workflow ### Step 1: Define Completion Criteria Specify clear success conditions: - All tests passing - No linter errors - Specific output marker (e.g., `<promise>DONE</promise>`) ### Step 2: Set Safety Limits Always use `--max-iterations` to prevent infinite loops. ### Step 3: Run the Loop ```bash # Basic loop iterative-runner "Build feature X" --completion-promise "DONE" --max-iterations 30 # TDD loop iterative-runner "Implement feature using TDD. 1. Write failing test 2. Implement to pass 3. Run tests 4. Fix if failing 5. Repeat Output <promise>DONE</promise> when all tests green." --max-iterations 50 ``` ## Prompt Best Practices 1. **Clear completion criteria** - Define what "done" means 2. **Incremental goals** - Break into phases 3. **Self-correction** - Include retry logic 4. **Escape hatch** - Always use --max-iterations ## Template ``` Implement [FEATURE]. Requirements: - [Requirement 1] - [Requirement 2] Success criteria: - All tests passing - No linter errors After 15 failed iterations: - Document blockers - List attempted approaches Output <promise>COMPLETE</promise> when done. ```
