Jason-hub-star Aim Before Build
This stage is read-only. Its cheapest valid outcome is discovering that no implementation is needed.
Workflow
- Separate the requested target from the action verb. Resolve project-specific terms from code or current documentation.
- Trace the relevant path end to end. Count completed behavior paths, not changed files.
- Check decisions, archived attempts, and recent commits for conflicts or previously rejected approaches.
- Return exactly one verdict:
CONFLICTING: the goal contradicts current architecture or a confirmed decision; do not start.ALREADY_DONE: the behavior exists and is verified; stop.PARTIAL: name the shortest missing end-to-end path.NOT_STARTED: identify the first owned path and whether planning risk is high.
An index or search result can prove presence, but an empty result alone cannot prove absence.
Output
Verdict, direct evidence, completed paths n/m, conflict history, and one next action.
Next
Use converge-plan for an expensive uncertain decision, goal-contract for multi-turn work with a clear target, or direct implementation for a small reversible change.
