rynmesh_fetch_peer_preview

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It mentions fetching 'directly from a peer endpoint,' which implies a network operation, but does not disclose possible side effects, security/trust implications, expected peer validation, error behavior, or whether this is a read-only operation.

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 one short sentence with the core action front-loaded. There is little wasted text, though 'Compatibility tool' adds limited value and could be removed or expanded into a more useful clue.

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?

Given no annotations, no output schema, and a crowded sibling list with several fetch-preview variants, the description is too thin. It does not explain endpoint format, expected_peer_id semantics, return behavior, or how this differs from rynmesh_fetch_peer_content_preview.

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. It adds some meaning for clip_id ('by clip ID'), but the required endpoint parameter is not described at all, and expected_peer_id is not mentioned. The description leaves the two most context-dependent parameters unexplained.

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 states a clear verb+resource: 'fetch a preview directly from a peer endpoint by clip ID.' It distinguishes this tool from local preview tools and from content-preview siblings by emphasizing 'peer endpoint' and 'clip ID.' However, the phrase 'Compatibility tool' is vague and does not clarify exactly what compatibility behavior is involved.

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 gives no guidance on when to use this tool versus sibling tools such as rynmesh_fetch_peer_content_preview, rynmesh_fetch_preview, or rynmesh_fetch_peer_full. It does not state prerequisites, when to prefer this over alternatives, or when not to use it.

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