disallowedTools

A Claude Code settings key, 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

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.

Changelog entries naming it

1. v2.1.236Deny rules match batched tools by the original tool name

   A disallowedTools rule now also blocks the batched wrapper around that tool.

2. v2.1.227agent() refuses spawns whose tool restrictions cannot be applied

   Spawning a sub-agent fails outright if its disallowed-tools list can't actually be applied.

A reference table page is one whose own table defines this name, and it is where the description above came from. A page that mentions it carries the name somewhere in its text and may say nothing about it at all. Every page carrying it.

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 settings key does. All settings keys.
