What it does

• Code search

Features 4

• Full code searchSemantic retrieval over the codebase that selects the relevant slice of code before the model spends tokens exploring.
• Intelligent context curationRetrieves, compresses and ranks context by task relevance instead of dumping the whole codebase into the prompt.
• Commit history contextGrounds retrieval in why changes were made, which reduces time agents spend on code archaeology.
• External sourcesBrings docs, tickets and design decisions into retrieval so agents avoid dead-end searches.

"Usage is measured in dollars across LLMs, Context Engine, and compute" on each plan, and every plan card lists Cosmos; the Cosmos page names the Context Engine among its building blocks. It is also offered to third-party agents through the Context Engine MCP ("1,000 free queries during launch"), a second route the one-route field cannot carry.
