DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

The same shell-preamble machinery would install a bq shim, and cannot currently be enabled

Bash Tool

The same shell preamble would install a bq shim on PATH, and cannot be turned on here.

The bq shim preamble builder always yields null because both accessors that would activate it return nothing.

What

The preamble this subsystem would add puts a bq shim on PATH from a per-version directory under Claude Code's temp root and can extend PYTHONPATH. No setting reaches it in this build: the two accessors that would activate it return nothing, so the preamble builder always yields null and the directory is never written.

Details
  • Remote config key tengu_sl_gate_config, in-source fallback all false with python_leg "on".
  • Telemetry bash_sl_gate includes a materialise_failed reason for a directory that could not be written.
  • The key does not appear in v2.1.238.
Evidence

sl-gate: could not write the carrier, off this process:

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
