Bwahahaha: anthropics / claude-code — [CRITICAL] Subagent spawning and subagent pattern bugs trigger infinite recursion, infinite token usage, grossly inefficient token usage, and lost accumulated subagent work. #68619

Multiple regressions compound into a catastrophic token burn scenario. Subagents recursively spawn child agents 50+ levels deep, ignoring CLAUDE_CODE_FORK_SUBAGENT=0. Permission denials trigger further agent spawning instead of stopping. Agents fetch individual files from GitHub repos via HTTP (one WebFetch or curl per file, each with a full prompt and context payload) instead of cloning locally. Subagent permissions do not propagate to the user for approval. And if the user interrupts any of this, all intermediate work from every agent in the tree is lost. The entire token spend goes in the garbage.

In the observed case: 1.2M+ tokens consumed in ~30 minutes on a task that should have been git clone + find . -name '*.sol'. The recursive agent tree was still growing when observed.
