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

With no annotations, the description carries the full behavioral burden, and it discloses almost nothing: no error behavior for unresolvable ids, no permission requirements, no side-effect profile. It only implies the tool is a lookup that returns fields.

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?

It is short and front-loaded, but it is a bare notation fragment rather than a concise sentence, and the terseness crosses into under-specification instead of efficient communication.

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?

With no annotations and no output schema, the description must carry the full load, yet it only gestures at the return fields (id, sid, type, path). For a 2-parameter tool whose semantics are unclear, this is inadequate.

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 100%, so both parameters are already documented in the schema and baseline is 3. The description's 'sid or full id' echoes the schema rather than adding format or constraint detail, and the listed id/sid/type/path are outputs, not parameters.

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 arrow notation states an input-to-output transformation (sid/full id in, id/sid/type/path out), so the resolution purpose is inferable. However, it never names what entity is being resolved, leaving it ambiguous against siblings like get_thread, get_paper, or explore.

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?

There is no statement of when to use this tool rather than an alternative, and none of the 35 siblings are referenced. The agent gets a capability hint but no routing guidance.

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