Claude Code's "mandatory" routing rules found non-functional

A user discovered that the "mandatory" routing rules in a CLAUDE.md file, intended to enforce specific tools for web fetching and command execution, were not actually functional in their Claude Code session. The file instructed against using `curl` or `wget`, instead directing users to `ctx_fetch_and_index` and `ctx_execute`. However, upon inspecting the available tools, the user found no `ctx_` prefixed tools, indicating the underlying infrastructure for these rules was absent. This discrepancy meant that if an explicit override instruction hadn't been provided, the agent would have failed to execute commands as intended, leading to errors or unexpected behavior without a clear recovery path.
