get_entity_configurations

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

No annotations are provided, so the description carries the full burden. It discloses that the tool is a discovery/read operation and what data it returns, but does not state whether it is safe/non-mutating, has side effects, requires auth, or provides caching. A 3 reflects adequate-but-incomplete behavioral disclosure for a no-annotation tool.

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?

Three short sentences, front-loaded with the core capability, followed by the usage trigger and the optional filter. No waste; every sentence contributes.

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?

The tool is a simple single-parameter discovery endpoint with no output schema. The description covers purpose, usage timing, and parameter behavior sufficiently for an agent to call it. Minor gap: it does not describe the shape of returned field metadata beyond a parenthetical list, which for a discovery tool would help the next step.

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 only one parameter at 100% schema coverage, the schema already fully documents 'entityType' including the enum values and the omission behavior. The description restates the optional filter ('Optionally filter by entityType') without adding syntax or format detail beyond the schema. Baseline 3 is appropriate.

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 ('Discover available entity types and their fields') and enumerates what is returned (field names, types, options, lifecycle operations). Clearly distinguishable from siblings like get_note_configurations and get_entity, which fetch different resources.

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?

Explicit when-to-use: 'Call this before creating or updating entities to learn what fields are available.' It names the relevant sibling operations (create/update) as the trigger, so the agent knows exactly when this tool precedes others.

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