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

No annotations are provided, so the description carries the full behavioral burden, yet 'Update hosted relay dismiss using privacy-filtered project metadata' discloses almost nothing: it never says whether the dismissal is reversible, what state the relay moves to, whether it consumes the handoff, what permissions are required, or what happens to the linked project/execution records. For a mutation tool this is a severe gap.

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?

It is a single short sentence with no filler, so it is concise, but the sentence is grammatically awkward and front-loads an ambiguous action ('Update ... dismiss') that obscures rather than anchors the meaning.

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 7-parameter mutation tool with no output schema, the description neither explains the effect of the operation nor how the required version/idempotency parameters interact with retries. It is far too thin to let an agent invoke this correctly against the crowded relay_* sibling set.

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?

With 7 parameters (4 required, including projectId, handoffId, idempotencyKey, expectedVersion) and a nested details object, the description adds no parameter meaning at all – it only vaguely gestures at 'project metadata' without mapping to any field. Even with 100% schema coverage, the schemas themselves are largely boilerplate, and the description does nothing to compensate for fields like handoffId, sessionId, or executionId.

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?

'Update hosted relay dismiss' largely restates the tool name rather than explaining what dismissing a relay actually does (decline/reject a pending handoff?). The resource is ambiguous – 'relay dismiss' is not clarified as an action on a handoff, session, or execution – and nothing distinguishes it from siblings like relay_accept, relay_release, or relay_mark_sent.

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 context is given: the description never states the condition under which an agent should dismiss a relay versus accepting, releasing, or re-polling it. There are no prerequisites, no exclusions, and no named alternative among the many relay_* siblings.

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