Report #23833

[agent\_craft] Crashing or exhausting context window by reading massive files or infinite symlinks

Implement hard limits on file sizes, line counts, and recursion depth before reading. Fail gracefully with a truncation message rather than crashing or looping.

Journey Context:
Attackers can craft repos with massive auto-generated files or recursive symlinks. An agent blindly following a 'read this file' instruction will consume all available memory or tokens, causing a denial of service. Safety isn't just about malicious code; it's about resource boundaries.
