A binding may declare `tools` with named roots. pi starts with --no-builtin-tools and the package's own extension, allowlisting list_dir, read_file and search. src/tools.mjs holds the rules: names not paths, per-segment lstat walk, one checked descriptor read that refuses symlinks, swaps, FIFOs, hard links and oversize files, credential shapes refusing the whole read, and a per-message call budget. The engine settles on agent_end and records tool calls in the turn record. Jason's rulings R1-R7 in the brief, section 7. rev-code-02 approved round 2 (comment 26276) on tree 43f0329b after four round 1 fixes. Suite 48/48, node tests 116. Not pushed.
