Everything you need to see what your agents did
Claude + Codex + Cursor capture
Three coding-agent harnesses, one unified local history and trace model.
Local-first storage
Everything stays in ~/.thirdeye/. No account or remote service required.
Pydantic Logfire export
Optionally mirror completed turns as nested OpenTelemetry traces without adding hook latency.
Per-turn token usage
JSONL sidecars + a SQLite index. Roll up by model, time, or platform.
Tag & search
Annotate any event with tags. Search substring or filter by platform, tag, or date.
Evals as rubrics
Named directive rubrics graded by an installed CLI agent as LLM-as-judge.
Sync to Logfire
Mirror completed agent turns to Pydantic Logfire as structured traces.
Open Thirdeye UI
Explore sessions, evals, usage, and settings in a local browser.
