export_to_faiss

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

With no annotations, the description must disclose behavioral traits. It only gives a generic fact about FAISS but does not mention whether the tool overwrites files, requires network access, or any side effects.

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

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

The description is short but includes an irrelevant sentence about FAISS capabilities that does not aid tool usage. The essential purpose is stated, but the structure could be improved by removing extraneous information.

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

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

The description is insufficient for a tool with 2 parameters and an output schema. It does not cover default behavior, required format, or return value, making the agent rely solely on parameter names.

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

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

Schema description coverage is 0% and the tool description provides no explanation for the two parameters (skill_dir and output_dir). This leaves the agent without context for input values.

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

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

The description clearly states 'Export skill to FAISS vector index format' which specifies a concrete verb and resource. It distinguishes from siblings like export_to_chroma, export_to_qdrant, etc., by naming the target format.

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

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

No guidance is provided on when to choose FAISS over other vector stores or any prerequisites. The description lacks context for comparing alternatives.

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