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

No annotations are provided, so the description bears full responsibility for disclosing behavior. It only says 'Transcript', revealing nothing about the operation's effects, output format, rate limits, or Instagram-specific constraints. This is a complete absence of behavioral transparency.

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?

While extremely short, this is under-specification rather than conciseness. The single word 'Transcript' does not convey enough information to be useful; it is not a well-structured description that efficiently communicates purpose.

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 tool with no output schema, no annotations, and a single parameter, the description is completely inadequate. It does not state what the tool returns, what Instagram content it applies to, or how it differs from the many similar sibling tools. The description fails to make the tool usable.

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% (the single 'url' parameter is described as 'Instagram post or reel URL'), so the baseline is 3. However, the description adds no additional meaning beyond the schema—no format details, constraints, or examples—so it remains at the baseline.

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 is simply the noun 'Transcript', which restates the tool name without adding any verb or resource. It does not explain what the tool actually does (e.g., retrieve transcripts for Instagram posts/reels) and fails to distinguish itself from many sibling tools.

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 guidance on when to use this tool versus alternatives. The description provides no context, prerequisites, or exclusions, leaving the agent without any basis for selecting this over similar scraping tools.

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