Manage Metrics

Collects wall-clock duration and token usage data per phase, generates incremental metrics.md reports in the plan directory.

Scope: hybrid means this skill stores data per-plan (.plan/plans/{plan_id}/) but can also enrich from the host platform's session transcripts on disk.

Enforcement

Base contract: See manage-contract.md for shared enforcement rules, TOON output format, and error response patterns.

Skill-specific constraints:

• Script-only skill — all access via the script API
• Never hard-code token values — only use data from Task agent <usage> tags
• Metrics data stored in .plan/plans/{plan_id}/work/metrics.toon; human-readable output in .plan/plans/{plan_id}/metrics.md
• Phase names must be one of: 1-init, 2-refine, 3-outline, 4-plan, 5-execute, 6-finalize (must match manage-status phases exactly)
