Session extract

Agent-facing primitive. Extract filtered content from a single Claude Code, Codex, or Cursor session file — either a conversation skeleton or error signals.

This skill exists so that agents do not read multi-megabyte session files into context. The scripts under scripts/ own the JSONL shape knowledge and emit a narrative-readable digest.

Arguments

Space-separated positional args:

1. <file> — absolute path to a session JSONL file (typically a file value returned by ce-session-inventory).
2. <mode> — skeleton or errors.
3. <limit> (optional) — head:N or tail:N to cap output at N lines (e.g., head:200). Omit to return full extraction.

Execution

Skeleton mode — narrative of user messages, assistant text, and collapsed tool-call summaries:
