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

The description adds rich behavioral context beyond annotations: idempotency ('return the existing link instead of creating a duplicate'), verification hold ('may stay unpublished in verification hold'), the fact that it is free and does not create a paid ad campaign, and the update behavior for customDescription. No contradiction with the provided annotations.

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?

One focused paragraph front-loads the primary usage rule, then efficiently covers caveats, exceptions, and output handling. Every sentence adds value—no filler or repetition.

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?

Despite the presence of an output schema and annotations, the description covers edge cases (playlists, duplicates, verification hold), non-goals (ad campaign creation), and final answer formatting. It is thorough enough for an agent to select and invoke the tool correctly in varied situations.

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 0%, so the description must compensate for explaining parameters. It only clarifies spotifyUrl (album/track/artist URL/URI) and customDescription (updates public description). Required artistId is left unexplained, and format, clientRequestId, and userIntentSummary have no semantic clarification despite non-obvious names.

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 a specific verb+resource ('create one free Dynamoi Smart Link from a Spotify album or track URL/URI') and clearly distinguishes itself from the sibling tool for full-catalog artist imports by naming the alternative. This makes the tool's purpose immediately clear and unique among siblings.

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?

Explicitly states when to use this tool ('Use this when the user wants to create one free...'), when not to use it ('Spotify playlist URLs are not supported today'), and names the preferred alternative for other cases ('For full-catalog artist imports or artist hub requests, prefer dynamoi_create_smart_links_from_spotify_artist').

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