Instructions
Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.
This server publishes no instructions, or was last inspected before Glama recorded them.

Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| antigravity_runA | Start one Antigravity CLI turn in a new conversation. Useful for repository research, a second opinion, and explicitly requested edits. Returns a conversation_id for follow-up. Up to 4 agy calls can run concurrently per server; excess calls return BUSY. Parallel calls share workspace files and your existing Antigravity account and quota. |
| antigravity_continueA | Follow up in an existing Antigravity conversation. Different explicit conversation_ids can run in parallel; simultaneous continuations of the same ID return BUSY. Without an ID, agy resumes its most recent conversation and requires exclusive access to this server, otherwise BUSY is returned. Other CLI sessions may change the latest conversation. Use the same workspace as the original turn. |
| antigravity_modelsA | List available model slugs and display names using agy models. Does not start a model turn; may contact the Antigravity service. |

Scored across 3 tools
Each tool has a distinct purpose: run starts a new conversation, continue follows up on an existing one, and models lists available models. There is no overlap or ambiguity between them.
All tools use the consistent 'antigravity_' prefix followed by a clear verb (run, continue, models). The naming pattern is uniform and predictable.
Three tools is an ideal size for this server's scope: it provides the essential operations for interacting with the Antigravity CLI (start, continue, list models) without unnecessary bloat or missing functionality.
The server covers the full lifecycle of an Antigravity turn: starting a new conversation, continuing it, and discovering available models. Given its focused purpose, there are no obvious gaps.
