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

Annotations are all false, so they provide no safety or side-effect profile, forcing the description to carry the burden. The description does disclose that it returns a 'stability verdict and observation count' and implies a read-oriented check, but it does not explain side effects, whether any state is written, or what the verdict range/semantics are. No contradiction with annotations, but transparency is only partial.

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 description is a single, well-structured sentence that front-loads the primary purpose and immediately follows with the return value. Every phrase earns its place, and there is no redundant restatement of the tool name or schema.

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?

With no output schema, the description should provide enough detail about return values and invocation context. It mentions a 'stability verdict and observation count' but leaves the verdict's form, possible values, and relationship to structured_data unclear. Given the large sibling set and all-false annotations, a bit more context would be needed for confident autonomous invocation.

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 100%, with all three parameters described meaningfully. The description adds the conceptual context of 'recent submissions' and 'established pattern,' but does not clarify how these map to the structured_data parameter. The schema already handles parameter documentation, so the description's contribution here is minimal but not harmful.

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 description clearly states a specific action ('check whether recent submissions still match the established pattern') and names the relevant resource ('this Blueprint'). It also indicates the output ('stability verdict and observation count'), giving enough specificity to distinguish it from many siblings, though it does not explicitly contrast it with related check tools like check_blueprint_health or check_realization.

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 gives no guidance on when to prefer this tool over alternatives, when not to use it, or what prerequisite context is needed. With many closely related sibling tools, the absence of any usage direction leaves the agent to infer suitability solely from the tool name and generic phrasing.

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