Cursor rules

Skill HKTITAN/cursor-sdk/skills/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).From its SKILL.md

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.md for nested context
Migrating from .cursorrules to .cursor/rules/*.mdc
Choosing between always-on, auto-attached, agent-requested, and manual rules
