generate_deck_images

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

With no annotations, the description carries the full burden and does disclose two important traits: the call is paid (monetary side effect) and it is gated behind a literal confirmation value 'GENERATE IMAGES'. It leaves out what happens to existing images, whether spend is bounded, and what the call returns, so it is good but not complete.

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 short sentences, zero filler, with the cost and scope constraint front-loaded and the confirmation requirement second. Nothing is wasted.

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?

No output schema and no annotations mean the description is the only source of behavioral detail, and it covers cost and the confirmation gate adequately. However, it omits prerequisites for obtaining approval_token, the expected result (e.g., a job identifier for status polling), and failure modes, leaving real gaps for a 3-required-param mutation.

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?

All three parameters have 0% schema description coverage, so the description must compensate. It explains only the confirmation parameter's required value; presentation and approval_token (where it comes from, what it authorizes) are left entirely undocumented in both schema and prose.

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 states a specific action (make paid image API calls) against a specific resource (slides in a deck), and scopes it to 'pending slides only'. That is enough for an agent to distinguish it from generation-preview siblings, though it never names an alternative explicitly.

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 'pending slides only' clause implies the precondition for calling it, and the required confirmation string hints at a gated workflow, but there is no explicit statement of when to choose this over preview_deck_generation or mark_slide_for_regeneration. Usage is inferable rather than stated.

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