get_chapter_backlog

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only says 'Get' which implies a read operation, but it does not describe what the backlog contains, whether it includes completed items, how results are ordered, or any other behavioral traits.

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 short and free of fluff, but it is so terse that it mostly restates the tool name ('chapter' + 'backlog'). It is concise without being informative, so it earns a middle score.

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 two required string parameters, no output schema, no annotations, and a family of similar backlog tools, the description is incomplete. An agent cannot determine what values to pass, what the response looks like, or how this tool differs from get_subject_backlog and get_backlog.

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 must compensate for the undocumented parameters. It mentions 'specific chapter,' which gives some meaning to the chapter parameter, but it completely ignores the required 'subject' parameter and does not clarify its format or relationship to the chapter.

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 states a specific verb ('Get') and resource ('backlog for a specific chapter'), so an agent can tell it is a chapter-scoped backlog retrieval. However, it does not explicitly distinguish it from sibling tools like get_subject_backlog or get_backlog, and it repeats much of the tool name.

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 guidance on when to use this tool versus alternatives such as get_subject_backlog or get_backlog. The description only implies a chapter-level scope and provides no context about selection criteria, prerequisites, or exclusions.

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