Claude Fable 5.1 took an opponent's chess engine in 3 of 10 honeypot games, the same week it solved a 1653 cipher in 44 minutes. Both runs argue for harnesses that enforce tool limits in the sandbox and grade the tool-call trace along with the result.

Claude Code keeps working whenever a Stop hook exits with code 2, so a 20-line script can hold the agent until the project's tests pass. The gate is only as strict as the command it runs, and the posted version lets Claude stop after four consecutive blocks.

Newer models ship with advice to keep the guidance file under 200 lines. The analyst who wrote those 1,042 lines argues each one logs context the model lacked, and that the real debt is a mechanical rule left sitting in prose.

Ben Mann's Labs group shipped Claude Code at a hit rate he puts at 20 to 30 percent, and the cheap part of that machine to copy is the two-week kill review rather than the research signal feeding it.

A testing-tools CEO writing for Forbes Tech Council argues that the check on an autonomous coding loop matters more than the model inside it, which puts the definition of done back where a manager has to write it.

Anthropic has cut 80% of Claude Code's system prompt. PostHog's audit of its own agent config file suggests the maintenance job now runs the other way, toward subtraction. A stale line is the cautionary case.
