Claude Duet harness engineering doc turned into a builder's guide
The author condenses Anthropic's 12-minute official Claude Duet harness engineering read into a builder guide covering isolated browser, credential proxy and independent checks, plus a brief-to-delivery pipeline with checkpoints and verification.
Anthropic just dropped the Claude Duet Harness Engineering 12-minute official read. isolated browser, credential proxy and independent checks around an agent that works while you’re away. i turned it into a practical harness guide for builders: brief → context → tools → observations → verification → repair → delivery → define what enters each step and what must come back → record tool results, artifact paths and errors → keep checkpoints so unfinished work can resume → verify the actual output against acceptance checks → send failures back for a focused repair → keep missing evidence marked UNVERIFIED → return files, setup instructions and check results i also added five runtime decisions and a worked example: CSV → searchable comparison board → checks → delivery packet save this, then read my article on harness engineering for my AI employee ↓
