What the code does

A tool parameter reaches a dangerous call

A value the model can set ends up inside a file or shell call. That is not a flaw by itself — for a terminal server it is the job — but it is where things go wrong when it is not.

A tool parameter reaches a file or shell call change_coupling.path → src/tools/engines.ts:50

        source = readFileSync(join(ctx.config.root, rel), 'utf8');

Code Atlas — questions

Answers built from our own checks of this server.

Why is there no uptime for Code Atlas?

Code Atlas runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package @lusiem/code-atlas was installed 46 times last week.

How do I connect Code Atlas?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls @lusiem/code-atlas straight from npm; nothing to host, nothing to sign up for.

How many people use Code Atlas?

The npm package @lusiem/code-atlas was installed 46 times in the last week. Week over week that is +37%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Code Atlas open source?

Yes — it is published under the MIT licence, written in TypeScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
