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.

Claude Code v2.1.248

Lists of sensitive config and credential paths

Under the hood
Useful2 Signal3
Permissions

New lists name sensitive config and credential files like .npmrc and .claude.json.

The lists exist; the guard that reads them is not in the same code.

What

New lists name config files treated specially, including .npmrc, .envrc, .mcp.json, .claude.json and .pre-commit-config.yaml, along with credential directory paths such as .config/gh and .claude/settings.local.json. Which file-access guard reads these lists is not decided in the same code, so no behaviour change is visible from them alone.

Evidence

.pre-commit-config.yaml

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