Get one claim in full

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

Annotations already declare readOnlyHint=true, so the description does not need to emphasize safety. It adds value by disclosing the full set of returned fields, including raw run ids, links, permalink, and citation string, which goes beyond the schema. No contradiction is present.

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 concise and front-loaded with the core action ('Fetch a single claim'), followed by a list of contents and an id example. Every sentence adds value, and the format is ideal for quick scanning.

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 single-id lookup tool with one parameter, complete schema coverage, and a readOnly annotation, the description fully covers what the agent needs to know: what it returns, what the id looks like, and the tool's non-mutating nature. No output schema exists, but the description lists the return fields explicitly.

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 coverage is 100%, and the description reinforces the id format with an example ('strix.qwen36.interactive2.c1.ttfa-nothink') and mentions the id pattern. This adds practical guidance beyond the schema's basic type description, though the schema already documents the parameter adequately.

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 the tool fetches a single claim by id and enumerates the exact fields returned, distinguishing it from siblings like list_measured and search_claims. The verb 'Fetch' and resource 'single claim from the AGmind registry' are specific, and the inclusion of an example id format adds clarity.

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 when a specific claim id is known and full detail is needed, but it does not explicitly state when not to use it or mention alternatives. Sibling tools exist (list_measured, search_claims), so more explicit guidance could help, but the context is clear enough for a targeted lookup tool.

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