Skill Retro

Analyze how skills performed in the current session and apply improvements via skill-creator.

Process

Step 1: Preprocess Session

Run the preprocessing script to extract a clean transcript from the current session's JSONL log:

node ${CLAUDE_SKILL_DIR}/scripts/preprocess.mjs --cwd <current-working-directory>

Capture the JSON output. Key fields:

• transcript_file — path to the temp file containing the full transcript (at ~/.claude/tmp/skill-retro-<session-id>.json)
• stats.skill_invocations — count of skills used

The script writes the full transcript to a temp file to avoid flooding the main thread's context window. Only the summary (stats + file path) appears in stdout.
