Kane CLI Hack Day

Attest

Kane CLI runs every step of a README or AI how-to in a real Chrome; each line comes back proven, stale or broken with a screenshot, and an agent fixes stale steps.

Documentation is the test suite nobody runs. Getting-started guides and AI how-to answers drift as UIs change, and AI coding agents learn from those docs, so a stale doc step becomes a hallucinated ag

Kane CLI Hack Day

See it work

1Ingest the doc at a fixed commit and number its lines
2Compile claims (shell, browser, prose) with line spans; fenced blocks become shell claims verbatim
3Run shell claims in a scratch directory; keep dev servers alive for the browser steps

03 · The harness

Kane CLI Hack Day

The intelligence behind shipping

Attest is the harness: it writes the Kane tests from a doc, runs them, reads Kane's evidence and decides a verdict per doc line. Kane is a witness, not a judge: each step stores the exact visible text closest to what the doc promised, so a renamed control comes back as stale with the new label instead of a failure. Stale or broken verdicts feed a closed loop (Codex patches only the doc, Kane re-proves). Every Kane run is filed with kanehack report. Attest's own README is proven by Kane (6 of 6).

01Compile the doc into claims pinned to line spans
02Write browser claims as a Kane _test.md, run testmd --agent
03Read NDJSON and the evidence pack, badge each doc line
04Agent patches stale steps, Kane re-proves from cache

What improved

Kane CLI runs every step of a README or AI how-to in a real Chrome; each line comes back proven, stale or broken with a screenshot, and an agent fixes stale steps.

3 doc steps Stale doc steps caught on live UIs and fixed (Vite heading, GitHub settings label, Attest README) (baseline 0 doc steps; source: https://github.com/SyberLabs/attest/blob/main/demo/cards.md)
5 loops closed Agent loops closed with the patched step re-proven by Kane (5 of 9 attempts; 10 dependent steps proven from the same run) (baseline 0 loops closed; source: https://github.com/SyberLabs/attest/blob/main/NOTES.md)
0 Kane credits Kane credits to re-prove the Vite doc after the fix, replayed from cache (vs authoring the same 3 steps) (baseline 48.5 Kane credits; source: https://github.com/SyberLabs/attest/blob/main/NOTES.md)
