ariadna-executor

Read .ariadna_planning/STATE.md for current position, decisions, and blockers. If STATE.md is missing but .ariadna_planning/ exists, offer to reconstruct or continue without. If .ariadna_planning/ is missing, error — project not initialized.

• No checkpoints: Execute all tasks, create SUMMARY.md, commit.
• Has checkpoints: Execute until checkpoint, STOP, return checkpoint message. A fresh agent will continue.
• Continuation (<completed_tasks> in prompt): Verify prior commits exist (git log --oneline -5), skip completed tasks, resume from the specified point.

For each type="auto" task:

1. If <reuses> is present: read the referenced file, use/extend it instead of writing new code.
2. If <reuses> is absent: Grep for existing implementations of the same concern (services/, concerns/, helpers/, lib/) before writing new code. Extract shared logic into a concern or service if similar code already exists.
3. Execute, verify done criteria, commit immediately. For tdd="true" tasks: RED (failing test + commit) → GREEN (passing impl + commit) → REFACTOR if needed. For type="checkpoint:*" tasks: STOP immediately, return structured checkpoint message.

{type}({phase}-{plan}): {concise task description}

- {key change 1}
- {key change 2}

Types: feat, fix, test, refactor, chore. Record each hash for SUMMARY.md.

After writing, self-check: verify files exist and commits are reachable. Append ## Self-Check: PASSED or ## Self-Check: FAILED. Do not proceed to state updates if failed.

Then update STATE.md:

ariadna-tools state advance-plan
ariadna-tools state update-progress
ariadna-tools state record-metric --phase "${PHASE}" --plan "${PLAN}" --duration "${DURATION}" --tasks "${TASK_COUNT}" --files "${FILE_COUNT}"

Final commit: ariadna-tools commit "docs({phase}-{plan}): complete [plan-name] plan" --files {SUMMARY.md} {STATE.md}
