TDQS

B3.4/5.0
Behavior4/5

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

Annotations already cover safety (readOnly, idempotent, non-destructive), and the description adds real behavioral detail beyond them: 20 unit rows per page, continuation via the returned next_page, and a filter-scope caveat. It does not say what the breakdown section contains or whether other sections paginate.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single compact sentence cluster with semicolons, front-loading the read action before pagination and filter caveats. Dense and largely waste-free, though the pagination clause is slightly cryptic about which section's next_page is meant.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

No output schema, so the description correctly covers the next_page return contract and paging limit, and the annotations handle the safety profile. Still incomplete for a 6-parameter tool: a third of the inputs have no stated meaning anywhere.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0% across 6 parameters, so the description carries the full burden. It only illuminates two of them — units_page (20 rows per page, follow next_page) and detachment_id (do not apply to unit rows) — leaving report_id, faction_id, release_id and dataset_revision unexplained.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb+resource: reads a report plus its breakdown-statistics first page. It is distinguishable from list_reports (list) and get_roster (roster) by the 'report + sub-statistics' framing, though it never names a sibling to contrast with.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is only implied — you call it when you have a report_id and need its detail. The one explicit guideline is a negative one: the detachment filter must not be applied to unit rows. No guidance on when to prefer list_reports or get_matchups instead.

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