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

Annotations already declare readOnly, idempotent, non-destructive; the description reinforces this with 'for reading' and adds concrete behavioral context: it loads metadata, timestamped narration transcript, and the context.md file, and it supports both URL or handle+slug targeting. No contradiction with annotations, and no hidden mutating side effects are implied.

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?

Three dense sentences, each with a distinct job: enumerate what is loaded, explain how to target it, and state the supported use cases with the slide-citation convention. There is no filler or repetition of schema/annotation data.

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 read-only, three-optional-parameter tool, the description covers identification, payload contents, ownership scope, and downstream usage/citation behavior. With an output schema and safety annotations present, no essential caller-facing information is missing.

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?

The main description adds the target-selection semantics that the schema leaves implicit: either the full watch URL or the handle+slug pair, with an example URL format. It also states the presentation need not be owned, which clarifies authorization scope. Slug still lacks its own schema description, but the OR-combination guidance compensates for the 67% schema coverage.

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 clearly identifies the action ('Load... for reading') and resource (shared Bisque presentation), and enumerates the distinctive payload: metadata, per-slide transcript with timestamps, and the author's context.md. It does not explicitly name sibling tools, so the differentiation from get_presentation_spec/analytics/status relies on the reader inferring that 'context/reading' is not those read-only views.

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?

It gives concrete usage context: use this when the task is to read, summarize, cite, or answer questions from a presentation, and it clarifies that the target need not be owned by the user. It does not explicitly state when not to use it or name alternative tools for metrics/spec/status.

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