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

With no annotations, the description carries the full burden of explaining side effects and requirements. It does not state whether this is a read-only operation, whether authentication or permissions are needed, or any error/rate-limit behavior. The only extra context is the output format (JSON-LD), which is minimal.

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, concise sentence that leads with the key concept (PROV-O history) and includes the output format. Every word adds value, and there is no wasted text.

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?

For a simple tool with one parameter and no output schema, the description is nearly adequate. It conveys the purpose and output format, but lacks crucial context about return structure, error conditions, or how this differs from related provenance/delta tools. A richer description would improve usability.

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 schema provides 0% description coverage, so the description must clarify the parameter. It does link the 'named graph' phrase to the required named_graph_iri, indicating the parameter identifies the target graph. However, it does not specify IRI format requirements or provide examples, so the added value is limited.

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 identifies the resource ('PROV-O ingestion/activity history for a named graph') and mentions the output format (JSON-LD), but lacks an explicit verb like 'get' or 'retrieve'. It does not clearly differentiate from sibling tools like brainkb_provenance_job or brainkb_delta_history, making the tool's exact action somewhat ambiguous.

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 use this tool versus alternatives. The description only states what it returns, not in what scenarios it is appropriate or preferable to sibling tools such as brainkb_provenance_job or brainkb_delta_history.

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