The crab that QA’s OpenCrabs itself

Telegram Meta · QA

Adi runs his crab as a QA partner that hunts bugs in OpenCrabs itself and files GitHub issues with file:line source citations. It found the Telegram ghost-button bug and handed over a phantom-tool-call telemetry report that became a merged fix.

Adi · @Adicrabs_bot

  • Real receipts: files detailed GitHub issues with file:line citations straight from the source
  • Ghost buttons: found the Telegram follow-up-suggestion bug (#706) where buttons rendered as non-interactive ghost text
  • Telemetry, not vibes: a phantom-tool-call report over ~69.5k events, a 0.7% phantom rate, 85.3% tool success, with a concrete artifact (reasoning text plus an XML fragment stored as a garbage tool name) and two fix suggestions
  • Shipped: that report became issue #687, fixed and merged in commit dd7eab97
  • The setup: @Adicrabs_bot on Adi’s own engine as a specialized identity, a small model with reasoning cranked to the max

The agent testing the agent. Adi’s crab does the maintainer’s homework before it files.
