session-summary

Write the per-session entry in a feature's session-log.md so the human can close the laptop and pick back up cleanly. The human-readable counterpart to the machine handoffs. checkpoint: null.

When to use

At the end of a work session on a feature. A lifecycle hook may nudge this workflow when supported by the current Codex hook schema; that hook is optional project config, not part of this skill.

Not for: mid-session (nothing's wrapping up); syncing the tracker (progress-log); per-skill records (each skill's own handoff).

Workflow

Resolve + scope — resolve the methodology root + manifest via ${PLUGIN_ROOT}/scripts/dae_resolve.py (see references/resolving.md). Scope = the feature(s) the session touched (default: current branch; multiple → an entry in each; none → nothing to log, stop).
Gather — synthesize from this session's handoffs/*.md, git activity on the branch, and conversation context (decisions, problems, deferrals).
Append the entry — append (never overwrite) to features/NNN-<slug>/session-log.md:
