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

Annotations only cover readOnlyHint=false/destructiveHint=false/openWorldHint=true; the description goes further by disclosing the return payload (number of matches replaced plus resulting slide text), noting no one is notified and the change is reversible in one call, and stating the required Cotlet API key scope. These are genuine additions beyond the structured fields.

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 lead sentences are redundant: 'Replace text on one slide, keeping its Smart Slide layout' is immediately restated as 'Replaces exact text on one slide and keeps its layout.' Later sentences (return value, reversibility, auth) earn their place, but the opening duplication wastes space.

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?

With no output schema, the description usefully covers the return value, the reversibility/no-notification behavior, and the required auth scope, so an agent has enough to invoke it correctly. Minor gaps remain (no explicit confirmation of failure behavior when the find text is absent).

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 every parameter (find, replace, slide_number, presentation_id) is already documented. The description confirms exact-text replacement but adds no syntax or format detail beyond the schema, 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 (Replace/Update) and resource (text on one slide) with a distinguishing constraint (keeps Smart Slide layout). An agent can readily separate it from siblings like set_speaker_notes or get_slides based on name and description alone.

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 scope ('on one slide') implies when to reach for it, but there is no explicit when-to-use vs when-not guidance or named alternative among the beautiful-ai siblings. 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.
