warmup_semantic_search

Initialize the embedding model and vector store for semantic search to prevent timeout on first query. Downloads and loads the Nomic model, runs a test embedding, and sets up the vector store connection.

Instructions

Pre-load the embedding model and vector store for semantic search.

Call this before your first semantic search to avoid timeout. Downloads and initializes the Nomic embedding model (~270MB) and creates the vector store connection.

The warmup process:

  1. Downloads the embedding model (if not cached)

  2. Loads the model into memory

  3. Runs a test embedding to warm up inference

  4. Initializes the vector store connection

Returns: Dictionary with warmup status: - status: "ready" if successful - model: Name of the embedding model loaded - dimensionality: Embedding dimensions configured - inference_mode: How embeddings are computed (local/remote) - test_embedding_size: Size of test embedding (confirms model works) - warmup_time_seconds: Time taken to warm up

Note: - First call downloads ~270MB model (takes 30-60 seconds) - Subsequent calls are instant (model cached on disk) - Model stays in memory for fast inference after warmup

Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries full burden. It thoroughly discloses the warmup process (download, load, test embedding, init vector store), mentions model size (~270MB), time estimates (30-60 seconds), caching behavior, and memory persistence. Output fields are fully described, leaving no behavioral ambiguity.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured with clear sections (main purpose, process steps, return values, notes). Every sentence adds value, and the information is front-loaded. There is no redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no parameters and a detailed output schema, the description is complete. It explains why to use it, what happens during execution, and what the return values mean. It addresses performance implications and caching, making it fully informative.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

There are zero parameters, so baseline is 4. The description does not need to add additional parameter information, and it appropriately focuses on the tool's behavior and return values.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: pre-loading the embedding model and vector store for semantic search. It uses specific verbs ('Pre-load', 'Downloads and initializes') and distinguishes itself from sibling semantic search tools by being a setup step to avoid timeouts.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description explicitly says to call this before the first semantic search to avoid timeout, providing clear usage context. It does not explicitly state when not to use, but the context strongly implies it is only needed as a one-time warmup, making the guidance adequate.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
