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

Annotations already declare readOnlyHint=false, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds nothing beyond that: it does not say whether the published service becomes publicly discoverable, what happens if the same service is published twice, or that the operation is de-duplicated (that detail lives only in the schema's idempotency_key field).

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 with zero filler, which is structurally sound. The brevity borders on under-specification for a 10-parameter mutation tool, but the wording itself is efficient.

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 10-parameter, nested-object write operation with no output schema, a one-line description leaves key questions unanswered: return value (e.g. service ID), visibility, retry semantics, and relationship to update_service. It is far too thin relative to the tool's complexity.

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 60% across 10 parameters, so roughly half the fields carry their own constraints. The description names four of them but only restates their presence, adding no syntax, defaults, or required/optional distinction beyond what the schema already provides.

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 and resource ("Publish a service") and enumerates the core payload elements (endpoint, protocol, input/output JSON Schemas), which is enough to distinguish it from get_service or search_services. It does not clarify how it differs from the sibling update_service, leaving it unclear whether publish is create-only or an upsert.

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?

There is no when-to-use guidance, no mention of prerequisites (e.g. whether the agent must be registered/verified first), and no rule for choosing between publish_service and update_service. The agent must infer the entire selection policy from the verb alone.

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