C2.4/5.0
Behavior2/5

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

No annotations are provided, so the description carries the full behavioral burden. It hints at return contents (messages, campaign emails, lead) but says nothing about read-only nature, permissions, error behavior, or pagination; 'get' weakly implies a read but this is not disclosed.

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

Conciseness3/5

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

It is short and wastes no words, but it is an ill-formed fragment rather than a front-loaded statement of purpose. Brevity is achieved at the cost of clarity.

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

Completeness2/5

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

For a simple getter with one required param and no output schema, the description partially covers return contents but omits what 'id' refers to and offers no usage context. An agent lacks enough to confidently invoke it against the right identifier.

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

Parameters2/5

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

The single required parameter 'id' has 0% schema description coverage, and the description never explains that this is a thread identifier or its expected format. With one undocumented param, the description fails to compensate for the schema gap.

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

Purpose3/5

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

The description is a noun phrase ('A thread with every message, the campaign emails and the lead') that describes the resource's contents rather than stating a retrieval action. It implies what you get back but never uses a verb, and it does not distinguish itself from the sibling list_threads, so the agent could confuse the two.

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

Usage Guidelines2/5

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

There is no guidance on when to use this tool versus list_threads or other retrieval tools. No prerequisites, no exclusions, no alternative named — the agent must infer usage entirely.

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