get_thread

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

No annotations are provided, so the description must cover behavioral traits. It includes a detailed section claiming no side effects, no authentication for basic usage, and local processing, but these contradict the presence of an 'api_key' parameter and the likely external API call. The description is internally inconsistent, reducing trustworthiness.

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 overly long with repetitive and irrelevant sections (e.g., generic transparency details not specific to get_thread). The first sentence is concise, but subsequent content is verbose and dilutes clarity.

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 tool has 4 parameters, no output schema, and no enums, yet the description omits return value structure, pagination info, or error cases specific to thread fetching. The generic error handling and behavior sections do not compensate for missing specifics.

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 0%, so the description must add meaning. The 'Args' section merely restates parameter names with generic phrases like 'The channel to analyze or process', adding no new information. It fails to explain format (e.g., thread_ts timestamp syntax) or the role of api_key.

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 first line clearly states the tool retrieves a full thread with replies, but the subsequent text describes it as providing structured analysis or classification, which is incongruent and confuses the purpose. The tool is partly distinguishable from siblings (get_thread vs. send_message), but the conflicting descriptions undermine 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 'When to use' and 'When NOT to use' sections are generic, referencing 'structured analysis' and 'real-time production decision-making', which do not align with the thread retrieval purpose. No guidance is given on when to prefer this tool over siblings like search_messages or list_channels.

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