Cursor Rules
Project, user, and team rules that the Cursor SDK and Agent load — `.cursor/rules/*.mdc`, `AGENTS.md`, and the legacy `.cursorrules`. Use when authoring rules that the SDK will pick up via `local.settingSources`, or when writing rule frontmatter with the right type (always / auto-attached / agent-requested / manual).

Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

cursor-rules
Rules are how you bake context into a project so every Agent run starts with the right instructions. The SDK reads them through local.settingSources — see [[../cursor-sdk/references/local-options]].
When to use
- Adding repo-level coding conventions an SDK agent should follow
- Writing per-folder
AGENTS.mdfor nested context - Migrating from
.cursorrulesto.cursor/rules/*.mdc - Choosing between always-on, auto-attached, agent-requested, and manual rules
File locations
- [[references/file-locations]] —
.cursor/rules/,AGENTS.md, legacy.cursorrules - [[references/scope-and-precedence]] — team / project / user, hierarchy
Authoring .mdc rules
- [[references/mdc-frontmatter]] —
description,globs,alwaysApply - [[references/rule-types]] — Always / Auto-attached / Agent-requested / Manual
- [[references/glob-patterns]] —
**/*.tsx, comma-separated lists
AGENTS.md
- [[references/agents-md]] — markdown-only, nested per directory
- [[references/agents-md-vs-rules]] — when to pick which
SDK integration
- [[references/sdk-integration]] —
settingSourcesand what loads where - [[references/limitations]] — Tab and Inline Edit don't read rules
