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

With no annotations, the description carries full burden and reveals key behaviors: calls an external API, costs $1 per call, consumes credits, returns a dict with status/remaining/constraint. It does not detail error handling or rate limits, but the main behavioral traits are well covered.

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 structured with a brief intro, cost note, Args list, and Returns summary. It is not overly verbose; each sentence serves a purpose. However, the Args section could be slightly more compact, but overall it is well-organized and front-loaded.

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?

Given the complexity (10 parameters, no annotations, no output schema), the description is largely complete: it explains the tool's purpose, cost, parameter semantics, and return format. It lacks details on error scenarios or edge cases, but the core information is sufficient for correct use.

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 schema has 0% description coverage, so the description fully compensates by explaining all 10 parameters: character_name as the character, q1-q4 as personality axes with options A-D, s1-s4 as style sliders with range 1-5 and defaults, and free_text as optional free-form input. This adds significant context beyond the schema's type/enum definitions.

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 the verb 'Generate' and the resource 'character constraints using the FIVE engine', and explains the purpose: to keep an LLM character's voice consistent. There are no sibling tools to differentiate, but the purpose is specific and unambiguous.

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 usage for generating character constraints but does not provide explicit when-to-use or when-not-to-use guidance. The cost disclosure ($1 per call) serves as a caution, but no exclusions or alternatives are mentioned, which is acceptable given no siblings.

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