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

Annotations already declare the safety profile (readOnlyHint=false, destructiveHint=false, openWorldHint=true). The description adds genuinely new context: the reversibility ('one call undoes it'), the rationale for running without asking, and an auth requirement ('Needs the user's Cotlet API key with access to this app'). It stops short of describing what a call returns or edge cases.

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?

Front-loaded with purpose and effect, then the reversibility/safety rationale and the auth note. Slightly bloated by the redundant 'Beautiful.ai:' prefix and the loosely worded 'It reaches no one', but overall tight for a simple toggle.

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 three-param toggle with full schema coverage and no output schema, the description covers purpose, effect, safety/reversibility, and auth. Complete enough to call correctly; only minor gaps remain around return behavior and position semantics.

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%, so skipped, slide_number, and presentation_id are fully documented in the schema. The description adds no format or syntax detail beyond that, so baseline 3 applies.

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 pair (skip/unskip) and resource (a slide), and clarifies the effect: the slide is left out when presenting or shown again. An agent can distinguish this from the other beautiful-ai slide tools without opening the schema.

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 phrase 'when presenting' gives a clear situational context, but there is no guidance on when not to use it or which sibling handles related slide operations (e.g., get_slides, update_slide_text). Usage is implied rather than explicitly scoped against alternatives.

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