csift

# csift — ripgrep for Claude Code session transcripts Surface: **v0.12.1** (must == `csift --version`). MECHANICAL GUARD: at first use after any compaction or context restore, run `csift --version` — if it differs from this Surface line, the copy you are reading is a stale in-context echo, and the installed SKILL.md is the one that matches the binary: Read it before anything else. Same diagnosis when an invocation you were CONFIDENT about errors (an older surface from prefill/summary/habit); never fall back to hand-parsing the jsonl. Rust CLI over CC session `.jsonl` under `~/.claude/projects/<encoded-cwd>/`. Built for an LLM consumer: token-lean text, uniform JSON, pure regex (RE2-class, linear-time; no backrefs/lookaround — they fail to compile by design). Smart-case: a pattern is case-insensitive unless it carries an uppercase; `-i` forces insensitive. `csift <cmd> --help` is the authoritative flag manual. Flag order is genuinely free — before/after the subcommand, before/after positionals, all equivalent. ## Why not hand-roll this format Every row below is measured, not hypothetical, and none of them threw an exception: a hand-written pass returns a plausible number that is wrong in a direction you cannot see. | what a hand-written pass does | what it actually returns | the csift move | |---|---|---| | filters `type:"user"` for human turns | **3.03x overcount** (3,607 vs 1,191 corpus-wide; 8.6x in the most multi-agent lane): peer-session inbox messages and harness no...
