A plain `.md` file in `.cursor/rules` is +ignored by Cursor itself for having the wrong extension, and is not measured +either. `AGENTS.md` is one of exactly four documented rule types ("a simple +alternative to `.cursor/rules`"), read from the project root and +subdirectories, with "Nested AGENTS.md support" listed as a shipped +improvement, so it is matched anywhere in the tree, the same reasoning +Copilot's own engine gives for the same file. + +**`.cursorrules` does not appear in current official docs at all.** The docs +list four rule types, Project Rules, User Rules, Team Rules and `AGENTS.md`, +and `.cursorrules` isn't one of them. Multiple independent community sources +describe it as still read, applied globally, just deprioritised in favour of +`.mdc` files, though no official source confirms this directly. Measured +either way. + +**Skill roots are measured anywhere in the tree, on purpose, the opposite +adjustment from the old `.cursor/rules` assumption this replaced.** Confirmed +directly: "Cursor walks the skills root recursively and picks up any +`SKILL.md` it finds", and separately, a `.cursor/skills/` (or +`.agents/skills/`, `.claude/skills/`, `.codex/skills/`) folder "anywhere +inside your repository is picked up, so monorepos can colocate skills with +the package they apply to", for example `apps/web/.cursor/skills/`. Both +behaviours are documented, not inferred. The category folder itself carries +no meaning to Cursor beyond organisation, for example +`.cursor/skills/shipping/land-it/`, with the skill's identity coming from the +folder that holds `SKILL.md`, so this engine keeps the category in its own +key for precision even though Cursor itself does not use it for identity. +Both of Cursor's Claude- and Codex-compatible skill roots are measured for +the same reason Copilot measures them: whichever directories Cursor actually +reads are this repository's Cursor composition, regardless of which vendor's +name is on the directory. + +## What it does not do + +- **It does not measure `~/.cursor/mcp.json`.** That is a home-directory file, + configured per developer, and it never arrives by pull request.

A file added three directories down changes how the +agent behaves in that subtree without touching anything at the root, and that +is exactly the change worth catching. Vendored directories (`node_modules`, +`vendor`, `.venv` and friends) are skipped, so a dependency shipping its own +`GEMINI.md` is not counted as yours. + +**Skills stay fixed at the repository root**, the opposite choice from +`GEMINI.md`. Gemini CLI's docs describe workspace skills as living within the +current directory, with no equivalent to Cursor's documented +monorepo-anywhere skill roots, so matching below the root here would not +reflect anything Gemini CLI actually does. + +**`.gemini/settings.json` is digested whole**, not parsed for the one +`mcpServers` key that matters. The same file carries unrelated settings, +including the `context.fileName` override mentioned below, and a parser that +mishandles the file would quietly report nothing changed about a file it +failed to read. So an unrelated settings edit shows up as MCP-adjacent drift. +That is a false positive a reviewer resolves by reading the diff, the same +tradeoff Copilot's engine makes for `devcontainer.json`, and the direction +worth being wrong in. + +## What it does not do + +- **It does not follow `context.fileName`.** Gemini CLI's `settings.json` can + rename the file it looks for away from `GEMINI.md`. Detecting an arbitrary + configured name would mean parsing `settings.json` first to know what to + even look for, real complexity for what is, today, a rarely used override. + This measures the documented default name and says so, rather than silently + covering less than a green check implies. +- **It does not measure `~/.gemini/GEMINI.md` or `~/.gemini/settings.json`.** + Both are home-directory files, configured per developer, and neither ever + arrives by pull request. A check that implied otherwise would be worse than + one that says nothing, the same reasoning Copilot's README gives for + `~/.copilot/mcp-config.json`. +- **It does not evaluate whether a context file is good.** It tells you one + changed and who changed it. Judgement is the reviewer's. +- **It is not a sandbox.** It reports composition, it does not constrain + execution. +- **It emits no signed record.** Same reasoning as Copilot: a repository + cannot know which model backs a given Gemini CLI session, since that is a + session-time choice, not fixed by anything in the repository.
