get_fixture_metadata

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

No annotations are provided, so the description carries the full burden. It states the tool 'Return' information, implying a read-only operation, but does not explicitly disclose side-effect-free behavior, auth requirements, or failure modes. For a simple metadata getter, this is adequate but not thorough.

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 a single sentence with no wasted words. It is front-loaded with the action and object, and every word contributes to meaning. Excellent conciseness.

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 provides enough information for an agent to understand the tool's purpose and what it returns. Given the zero-parameter schema and the presence of an output schema, the description is complete for the tool's low complexity, though it doesn't elaborate on what 'provenance' entails.

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?

The tool takes zero parameters, so the baseline is 4. The description adds no parameter-specific context because none is needed. It correctly focuses on what the tool returns rather than parameter details.

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 states a specific verb (Return) and resource (provenance and version information for the active graph fixture). It clearly distinguishes from sibling tools like search_graph and generate_java_test, which serve entirely different purposes. The purpose is unambiguous.

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?

The description implies use for retrieving metadata about the active graph fixture, which is clear given the tool name and siblings. However, it does not explicitly state when not to use it or mention alternatives. The context is clear enough that an agent would not confuse it with the search or test generation tools.

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