get_chapters

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

The annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true, and openWorldHint=true, covering the safety profile. The description adds no further behavioral context such as scoping, return format, or pagination behavior, so it provides no value beyond the structured annotations.

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?

"List Chapters" is extremely short and front-loaded, but it is under-specified rather than optimally concise. For a tool with many chapter-related siblings, this brevity leaves critical context out.

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 simple and its annotations and schema cover safety and the required parameter, but the description does not state that chapters are listed for a specific project. It also fails to clarify its relationship to the other chapter endpoints, leaving an agent with insufficient context for reliable selection.

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 100%, and the single project_id parameter is fully documented in the schema itself. The description adds no parameter meaning, but with high schema coverage the baseline score is 3.

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?

"List Chapters" essentially restates the tool name get_chapters and title Get Chapters, making it tautological. It gives no project scope or sibling differentiation, so an agent cannot distinguish it from get_chapter_by_id_endpoint or get_chapter_snapshots using the description alone.

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?

There is no when-to-use guidance, no mention of alternatives, and no indication of when not to use this tool. The agent is left to infer usage from the schema and name alone.

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