sentinel_manifest

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

With no annotations, the description carries the burden, and 'Read-only public GET' usefully discloses the safety profile and that no authentication is required. However, it says nothing about return format, size, or caching behavior for what is effectively a schema document.

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?

A single front-loaded sentence that identifies the resource, lists its contents, and states the access profile with zero waste.

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 zero-parameter meta tool with no output schema, the description adequately signals what the caller will receive (endpoints, schemas, license, reliability commitment). Minor gap: it does not hint at how an agent should use the manifest once retrieved.

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 tool takes zero parameters, so the baseline of 4 applies; there is no parameter surface for the description to explain or for the schema to omit.

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 resource (the Sentinel service manifest) and enumerates its contents: endpoints, response schemas, license and reliability commitment. It is clearly a discovery/meta tool distinct from the data-returning sentinel_* siblings, though it does not name any sibling explicitly.

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?

No when-to-use guidance and no alternatives are named. The agent must infer that this is a bootstrap/discovery call; nothing tells it when this is preferable to, say, sentinel_accuracy or sentinel_current_risk.

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