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

Annotations already declare destructiveHint=true and openWorldHint=true, so the safety profile is carried by structured data. The description adds genuine behavioral context beyond that: header values 'are never shown back' (a write-only/redaction trait) and the default signals behavior. It does not explain what delete destroys or the auth specifics, so it is adequate but not rich.

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?

Two sentences, front-loaded with what the resource is, then the create and flush specifics. Dense but efficient, and each clause carries information. Slightly terse given the tool's complexity.

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?

This is a six-action, seven-parameter management tool with no output schema and no annotation coverage of the CRUD lifecycle. The description addresses only create and flush and omits list/get/update/delete entirely, so it is not complete enough for an agent to safely operate all actions.

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 57%, so the schema does part of the work but the description should compensate more. It adds meaning for endpoint (OTLP base URL), headers, and the 'both by default' behavior for signals, but says nothing about id, enabled, action semantics, or idempotencyKey. Marginal value over the already-documented fields.

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 (OpenTelemetry exports pushing sandbox OTLP logs and CPU/memory metrics) and explains the create/flush semantics. However, it frames the tool only around create and flush, leaving the multiplexed list/get/update/delete actions of the action enum effectively unstated, so an agent cannot fully tell what the tool manages.

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 implies when create is used (takes endpoint, headers, signals) and when flush is used ('flush pushes now'), but gives no guidance for list/get/update/delete actions, no when-not conditions, and no alternatives among siblings. Usage is largely left to inference from the action enum.

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