validate_reviewed_chapter_quiz

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

With no annotations, the description carries the full behavioral burden. It usefully discloses that the tool does not stage, select, or submit, which suggests limited state change, but it does not state whether validation is read-only, what permissions are required, or how failures are reported.

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 definition is a single front-loaded sentence with no filler. It is concise and readable, though its terseness leaves important semantic gaps that are penalized elsewhere.

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?

An output schema exists, so return values need not be explained. But for a tool with three required, completely undocumented parameters and no annotations, the description should define the review/evidence format and validation criteria; it does not.

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%, and the description does not mention any of the three required parameters: observation_id, answers, or reviews. It adds no meaning beyond the bare property names in the schema.

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 and resource: validate review format/evidence. It also distinguishes the operation from staging, selecting, and submitting, which separates it from the submit_reviewed_chapter_quiz sibling. The main limitation is that 'review format/evidence' is somewhat abstract without saying 'chapter quiz' explicitly.

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 phrase 'without staging, selecting or submitting' implies this is a pre-submission validation step and not a submission action. However, it does not explicitly say when to call this instead of submit_reviewed_chapter_quiz or other quiz tools, nor does it describe prerequisites or expected workflow.

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