ponens
Turn an AI agent's session into a reviewable, verifiable reasoning record — and govern it.
pip install ponens
When an AI coding agent finishes, all you really have is a diff and a chat log. ponens turns that
into a reasoning trace: a structured, reviewable record of what was built and why — the steps,
the decisions, the artifacts and their lineage, the declared goal and whether it was met, what was
verified, and what was left uncertain — at the altitude a reviewer actually reads, not a replay of
the dialogue.
Reasoner-agnostic, local-first (no backend required), MIT-licensed.

Quick start
pip install ponens
ponens emit -o trace.json # capture an agent session as a reasoning trace
ponens trace view trace.json # open the interactive viewer (flow · lineage · goals · policies)
ponens trace grade trace.json # score the record on a reviewer-oriented rubric
ponens trace check trace.json # computable governance — machine-checked policies, PASS/FAIL
Already instrumented with OpenTelemetry or Langfuse? Bring those traces in and add the governance layer:
ponens otel import spans.json -o trace.json
ponens langfuse import lf.json -o trace.json
What you get
- A reasoning trace, not a transcript — atomic actions, typed artifacts, and a lineage DAG (what produced what), plus a declared residual surface (the gaps the agent left open).
- Goals graded met vs certified — did it meet its definition of done (resolved from the trace's own evidence), and did a reviewer other than the doer confirm that was the right definition? "Done" separated from "right."
- Computable governance — organizational and best-practice policies as machine-checked formulas over the trace (temporal + structural), a deterministic PASS/FAIL gate that runs offline in CI. Ready policy packs (formal-methods, the FIX Community's AI guidelines, and more) in the gallery.
- An interactive viewer —
ponens trace viewrenders the flow, the lineage graph, the goals, and the policy verdicts in a single self-contained page.
