Distill Sessions

Turn raw session transcripts into a ranked list of concrete improvements. Read-only analysis of the logs; never modify the log files. Output a numbered proposal list with one verbatim (redacted) evidence line per finding, then let the user pick which to apply.

Where the logs live

• Claude Code: ~/.claude/projects/<slug>/*.jsonl (top-level sessions). Per-session subagent transcripts are under <uuid>/subagents/agent-*.jsonl — skip these when counting "sessions"; they're part of a parent.
• Codex: ~/.codex/sessions/<year>/<month>/<day>/rollout-*.jsonl.

Both are JSONL — one event per line.

1. Pick the N most recent sessions

Default N = 50 unless the user gives a number. date/strftime may be missing from the shell — use perl for timestamps.
