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

With no annotations, the description carries the full burden and mostly delivers: it declares 'Free, no side effects', explains that unregistered tools appear with registered: false and in a top-level unregistered array, and notes the live-wire vs registry diff for deploy-drift detection. It does not discuss pagination or size limits, but for a no-arg read this is strong disclosure.

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 core purpose is front-loaded and clear, but the deploy-drift/unregistered explanation is stated twice (issue #174 and again for issue #175) in near-identical wording, and the canonical-UUID aside adds length without adding invocation value. The duplication dilutes an otherwise well-structured description.

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?

An output schema exists, so return-shape detail is not required here, and the description still covers purpose, audience, safety, and the edge case of unregistered tools. For a zero-param, read-only tool it is essentially complete, with only pagination/size behavior left unstated.

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 is 4; there is nothing for the description to clarify beyond what the empty schema already states.

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 first sentence states a specific verb (Return) and resource (canonical (tool_id, mcp_name, ...) for every exposed tool), which no sibling tool provides. An agent can distinguish this registry-identity dump from beesknees_list_constraint_types or beesknees_list_coupons without opening any schema.

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?

It names the consumers and the reason to call it: 'The authoritative source for any client (Studio, agents, FE)' and 'Reconcile uses this output to UUID-join against the stored pricing model'. That is clear usage context, but no explicit when-not-to-use or named alternative is given.

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