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 / Environment variables

CLAUDE_CODE_TOOL_MEMORY_CGROUP_EXCLUDE

A Claude Code environment variable, 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

Memory limits now reach npm, git, tmux, LSP, MCP and hooks, but everything except Bash is excluded.

Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.246.

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. v2.1.246Per-class memory caps on spawned processes, wired through but off for everything except Bash

    Memory limits now reach npm, git, tmux, LSP, MCP and hooks, but everything except Bash is excluded.

    named in this entry

  2. v2.1.246Tool subprocesses can be launched inside a memory-capped cgroup

    MCP servers, hooks, plugin installs and tmux sessions can run under a memory cap, dark-launched here.

    named in this entry

Documentation pages

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.

Names beside it

Every environment variable in the inventory starting claude_code_tool_memory, up to twelve of them.

CLAUDE_CODE_TOOL_MEMORY_LIMITOn Linux you can cap memory for shell commands so a runaway process cannot eat your machine. 2.1.233

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 environment variable does. All environment variables.
