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

Goes well beyond annotations (readOnly=false, idempotent=false, destructive=false) by disclosing that nothing is pinned or published, that the full updated page JSON is returned, that the caller must pin to IPFS and sign updatePage themselves on a named Registry contract, gas cost, and that the server never signs. This is exactly the extra behavioral context the annotations don't carry.

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?

Dense but front-loaded: scope first, then prepare semantics, then the follow-up flow, then parameter options. Every sentence carries information, though the contract/signature detail is packed into one long clause that could be trimmed slightly.

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 correctly states the return (complete updated page JSON) and the required downstream steps (pin to IPFS, call updatePage). Combined with scope and parameter paths, an agent has everything needed to invoke and complete the workflow.

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% so the baseline is 3, but the description assembles the either/or logic: add accepts track_url OR ipfs_cid, remove matches by track_index OR track_url. That mapping of mutually exclusive paths adds meaning beyond the per-field schema text.

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 (add/remove) and resource (a track on the music block) with the exact scope (agent_username's own page, no target-page parameter). It clearly separates itself from sibling prepare_* tools by describing a track-mutation workflow.

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?

Gives clear context on when to use it and its constraints (own page only, prepare-don't-execute), plus the follow-up steps to actually apply changes. It stops short of naming a specific sibling alternative for related page edits, so it's strong but not fully explicit about when-not.

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