Features

  • spec: add opt-in AI usage tracking to spec new (#20)

Gate AI usage tracking behind a new --usage flag on /spec new. When
set, a background subagent monitors the executing agent's session
files and writes token/tool telemetry to ai-usage.md inside the plan
directory. Behaviour is byte-for-byte unchanged when the flag is
absent.

Wiring

  • Add USAGE_MODE parsing plus monitor and finalize steps to the new
    workflow.
  • Add ai-usage-template.md and usage-monitor.md references.
  • Document --usage in SKILL.md.

Session detection and aggregation

  • Select the cwd-matching session file (skip the subagent's own
    transcript) so a background monitor measures the parent planning
    session, not itself.
  • Bound token and tool aggregation to USAGE_START_EPOCH via each
    line's timestamp, matching the advertised planning window.
  • Guard the best-effort other-agent probe with nullglob/globstar so
    placeholder globs expand instead of staying literal.
  • Support Claude Code as a first-class source and other agents on a
    best-effort basis with graceful degradation.

Reporting

  • Relabel the usage Total row "Total (all classes)" and clarify it is
    a tokens-processed record, not a cost figure.
