Cursor rules documentation alwaysApply globs description-based selection rule activation standalone chat
💡 Result:
In Cursor, rules are managed using.mdc files located in the.cursor/rules/ directory [1][2][3]. These files utilize YAML frontmatter to determine how and when they are applied, replacing the legacy root-level.cursorrules file [2][4][5]. The application behavior is controlled by three primary frontmatter fields: alwaysApply, globs, and description [1][6][3]. Based on how these are set, rules fall into one of four activation categories: 1. Always Apply: Set alwaysApply: true. The rule is included in every chat session regardless of context [1][7][6]. Other fields (globs, description) are ignored [1][8][3]. Use this sparingly for repo-wide, non-negotiable constraints [7][9][3]. 2. Apply to Specific Files (Auto-attached): Set alwaysApply: false and provide a globs pattern [7][8][6]. The rule is automatically added to the context when an edited or referenced file matches the specified glob pattern [1][7][3]. Globs should be defined as a comma-separated string (e.g., globs: src//.ts, src//.tsx) [7][8][6]. 3. Apply Intelligently (Agent-selected): Set alwaysApply: false, include a description, and leave globs empty [1][7][8]. The Cursor Agent reads the description and determines if the rule is relevant to the current task [1][6][10]. 4. Apply Manually: Set alwaysApply: false and leave both globs and description omitted [7][8][6]. The rule remains dormant and is only included when you explicitly @-mention it in chat (e.g., @my-rule) [1][7][3]. To ensure rules function correctly, they must have the.mdc extension; plain.md files in the.cursor/rules directory are ignored because they lack the necessary metadata structure [1][7][2][6]. Legacy.cursorrules files are often ignored by modern Agent modes and should be migrated to the.mdc directory format for consistent performance [2][4]. Standalone chat sessions and Agent interactions utilize these rules to maintain context-aware guidance throughout your workflow [7][6][4].

Apply this rule to standalone documentation lookups.
With alwaysApply: false, globs: ["**/*"] auto-attaches the rule only when an edited or referenced file matches the glob. A standalone API lookup can therefore bypass the rule. If the policy must apply to every chat, set alwaysApply: true. Otherwise, remove globs and use description-based selection.

Do not use broad github.com as an official-documentation filter.
The host-wide filter can return arbitrary repositories, forks, issues, or user pages. This conflicts with the rule's requirement to use official documentation.
Remove github.com from the example or require a project-specific official repository scope.

Define a fail-closed freshness policy.
The rule only requires checking fetched_at; it does not define a freshness threshold or handling for missing or stale timestamps. Require an ISO-8601 timestamp, reject or re-fetch stale results, and include the exact fetched_at value when citing documentation.
