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.

Reference / Feature flags

tengu_remote_tool_classifier

A Claude Code feature flag, read out of the shipped bundle. No mined inventory carries it: everything below comes from what this site has written about it.

What it is

Tool calls and Bash can be routed to another machine over a device bridge.

Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.242.

Presence across releases

The miner has never read a build containing this name. It is here because a changelog entry of ours names it, which is evidence that it existed and not evidence of which releases carried it. The inventory starts at v2.1.138 and everything older than that was never mined.

Gate readings

No release here has a gate table behind it for this flag. Most published releases have none at all: the readings exist only for versions the pipeline captured flag state on.

Changelog entries naming it

  1. v2.1.248Remote host tool classification extended beyond Bash

    Remote hosts now classify more than just Bash calls when deciding what's allowed.

    gate cited by this entry

  2. v2.1.242Groundwork for running tools on another machine over the device bridge

    Tool calls and Bash can be routed to another machine over a device bridge.

Documentation pages

None of Anthropic's documentation pages this site has a copy of carries this name.

Read out of the published npm bundle release by release, and out of Anthropic's own documentation as this site captured it. Nothing on this page is a description anybody here wrote about what the feature flag does. All feature flags.
