Ir-Kat — Do The Work

Execute a complete phase cycle: plan with Scribe, build with Builder, review with Overseer. If the Overseer kicks back, the Builder fixes and the Overseer re-reviews, up to 3 attempts.

The PHASE_PROMPT is provided via $ARGUMENTS. It can be either:

• Inline prompt text
• A file path to a PHASE_PROMPT.md

Step 1: Create task list

Create tasks for the phase loop:

1. "Validate PHASE_PROMPT" — Validating PHASE_PROMPT
2. "Plan phase with Scribe" — Planning phase with Scribe
3. "Build phase with Builder" — Building phase with Builder
4. "Review phase with Overseer" — Reviewing phase with Overseer
5. "Report result" — Reporting result

Step 2: Validate PHASE_PROMPT

Mark task 1 as in_progress.

If $ARGUMENTS looks like a file path (ends in .md or contains /), read the file. Otherwise, treat $ARGUMENTS as the prompt text directly.

Verify the prompt is non-empty and contains meaningful content.

If invalid, mark task 1 as completed, report the error, and stop.

Mark task 1 as completed.

Step 3: Plan phase with Scribe

Mark task 2 as in_progress.

Use the Task tool to invoke @ushabti:scribe with the following prompt:

Plan a phase from the following PHASE_PROMPT. Follow your standard procedure — read laws, style, docs, and existing phases, then create the phase directory with phase.md, steps.md, and progress.yaml.

PHASE_PROMPT: {the prompt content from Step 2}

Wait for the Scribe to complete. Verify that the phase directory was created by invoking the find-current-phase skill. The newest phase with status planned is the one just created.

If the Scribe failed, report the error and stop.

Mark task 2 as completed.

Step 4: Build phase with Builder

Mark task 3 as in_progress.

Use the Task tool to invoke @ushabti:builder with the following prompt:

Implement the current phase. Follow your standard procedure — read laws, style, docs, find the current phase, and implement all steps. Update progress.yaml as you go. When all steps are complete, set the phase status to review.

Wait for the Builder to complete. Verify the phase status is now review by invoking the get-phase-status skill.

If the Builder failed, report the error and stop.

Mark task 3 as completed.

Step 5: Review phase with Overseer

Mark task 4 as in_progress.

Set a retry counter to 0.

Use the Task tool to invoke @ushabti:overseer with the following prompt:

Review the current phase. Follow your standard procedure — read laws, style, the phase files, and the code changes. Verify acceptance criteria are met. Either declare the phase green (status: complete) or kick it back (status: building) with specific feedback.

Wait for the Overseer to complete.

Check the phase status by invoking the get-phase-status skill:

If status is complete: The phase is green. Mark task 4 as completed. Proceed to Step 6.

If status is building (kicked back): Increment retry counter.

• If retry counter < 3:

  • Read the review file (.ushabti/phases/{phase}/review.md) to understand what the Overseer found.
  • Use the Task tool to invoke @ushabti:builder with the following prompt:

    The Overseer reviewed the current phase and kicked it back. Read the review at .ushabti/phases/{phase}/review.md for details. Fix the issues identified, then set the phase status back to review.

  • When the Builder completes, invoke @ushabti:overseer again with the same prompt as above.
  • Repeat this check.

• If retry counter >= 3:

  • The phase is blocked. Mark task 4 as completed. Proceed to Step 6 with outcome "blocked".

Step 6: Report result

Mark task 5 as in_progress.

Report the outcome:

If green:

Phase loop complete. The phase has been planned, built, and reviewed successfully.

• Phase: {phase directory name}
• Status: GREEN
• Review cycles: {retry counter + 1}

If blocked:

Phase loop blocked after 3 review cycles. Manual intervention required.

• Phase: {phase directory name}
• Status: BLOCKED
• Last review: see .ushabti/phases/{phase}/review.md

Mark task 5 as completed.
