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

The description asserts a read-only retrieval operation ('Hämtar') while annotations include destructiveHint: true, directly contradicting the expected side-effect profile. This contradiction warrants a score of 1 despite the description adding useful context about error behavior and AI review.

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 description is four sentences, each contributing: purpose, error semantics, content provenance, and optional parameter explanation. It is front-loaded with the primary action and avoids redundancy.

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 simple retrieve-by-ID tool with no output schema, the description covers the main returns, error handling, optional transcript, and content generation process. It is sufficiently detailed for an agent to invoke correctly.

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 coverage is 100%, but the description adds meaning for include_transcript by clarifying that the transcript is Aapl.se's own content, not a third-party source. This extra context helps agents decide whether to request it, raising the score above baseline.

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 uses the specific verb 'Hämtar' and clearly identifies the resource as a single episode of Aapl Pod, listing return fields (title, description, chapters, sources). It distinguishes from sibling list_podd_episodes by focusing on an individual episode via ID.

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 description implies usage for fetching a single known episode, but does not explicitly state when to use it over siblings like list_podd_episodes. The unknown-ID error handling is noted, but no explicit exclusions or alternatives are named.

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