create_chapter

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

No annotations exist, so the description must disclose behavioral traits. It mentions creation but omits whether it is destructive (creates a new record), permission requirements, idempotency, or side effects. The code constraint is the only behavioral detail.

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 brief (one sentence plus a constraint), but it could be restructured to front-load the core purpose while incorporating more parameter details. It is not overly verbose, but minimalism sacrifices clarity.

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 tool's complexity (5 parameters, 3 required, no output schema), the description is incomplete. It lacks explanation of return values, error conditions, or the relationship between project_id and chapter hierarchy. The code constraint is the only substantive addition.

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 0%, so the description should compensate. It adds meaning only for the 'code' parameter (format constraint). Other parameters (project_id, name, description, order) have no additional explanation, leaving their semantics to the schema titles alone.

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 action (Create) and the resource (a chapter under a project). It distinguishes from siblings like create_section or create_item by specifying the parent context.

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 the tool is used to create chapters, but it does not provide when-not-to-use guidance or mention alternative tools like list_chapters or bulk_create_items. The code format hint is helpful but not sufficient.

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