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

Annotations already establish a safe, idempotent, closed-world read, so the description correctly spends its words elsewhere: it discloses that results are paged ('one bounded page') and that the payload is untrusted user-derived data — a real security-relevant trait absent from the annotations. It could go further on error behavior when the artifact is missing or not yet generated.

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?

Two sentences, no filler, with the trust warning placed last as a deliberate caveat. Every clause carries information.

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 output schema means return values need no explanation, but a 5-parameter tool with 0% schema coverage and several similarly named siblings is under-served by two sentences. Key unknowns — when artifacts become readable, how targetLanguage interacts with the artifact enum, how to page with cursor — remain undocumented.

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 0%, so the description must carry the parameter burden, and it only partly does: the artifact list in prose loosely maps to the enum, and 'bounded page' gestures at cursor/characterBudget. It says nothing about targetLanguage (presumably required for the translation artifact), cursor semantics, or how characterBudget trades off against page size.

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?

States a specific verb (reads) and resource (a generated transcript artifact) and enumerates the artifact kinds it can return. It implies a distinction from raw transcript reads via 'completed ... artifact', but never names get_transcript, summarize_transcript, or the other generators it sits alongside.

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?

No explicit when-to-use, when-not-to-use, or alternative tool is given. 'Completed' weakly implies the artifact must already be generated, and 'one bounded page' hints at pagination, but an agent gets no guidance on choosing this over get_transcript or on what to do when no artifact exists yet.

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