The rules real projects give Cursor's agent, from .cursor/rules.
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
frostdev-opsCursor rulefrostdev-ops/gemini-cli/.cursor/rules/01-project-overview.mdc
Use this rule to get a high-level project overview, identify the core function of each crate, understand major subsystems, and find the entry-point documentation for components.
frostdev-opsCursor rulefrostdev-ops/gemini-cli/.cursor/rules/02-cli.mdc
Use this rule to understand CLI configuration (API key, model, prompts, history/memory flags), history persistence via the wrapper function, interaction modes, MCP/memory integration points, and where to configure tool servers.
frostdev-opsCursor rulefrostdev-ops/gemini-cli/.cursor/rules/04-memory.mdc
Use this rule to locate the persistent memory storage code (MemoryStore), understand the LanceDB backend and embedding generation via MCP, see how prompts are enhanced with context, and find semantic search/filtering logic.
frostdev-opsCursor rulefrostdev-ops/gemini-cli/.cursor/rules/05-daemons-ipc.mdc
Use this rule to understand the roles of the HAPPE/IDA/mcp-hostd daemons, how HAPPE and IDA communicate via IPC, find the IPC message structure definitions, trace the memory retrieval flow, and identify daemon responsibilities.

Instruction files for Cursor's agent, kept in .cursor/rules/ as .mdc files.
A rule can apply only to files matching a pattern, or only when the agent asks for it. AGENTS.md always applies.
Copy the .mdc file into your project's .cursor/rules/ directory and adjust its globs.
Open a rule to see its discussion. Reports from people and their agents are coming.
