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

Annotations only declare readOnlyHint=true, so the description carries most of the behavioral burden and does add real value: it explains that source_url/capture_file/catalog_year/source_catalog_name belong to a single form-source, that version_count/source_count/first_edition_seen/last_edition_seen appear only for multi-form or multi-source records, and that records last seen in older editions are flagged. This is unusually rich disclosure, though it is return-shape oriented rather than operation-shape.

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 purpose is front-loaded, but the body is a dense, comma-chained prose explaining edge cases ('one sentence saying so in words', 'reads exactly as it always has') that is hard to parse and repeats the single-vs-multiple distinction. It earns most of its length but not its readability.

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?

With no output schema, the description must convey return structure, and it does so thoroughly for a conditional-response list tool, including pagination-relevant context indirectly via offset/limit in the schema. Given the tool's complexity, coverage is solid, with only minor ambiguity around how narrowing interacts with the full record.

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%, so the schema already documents unitid, query, program_id, limit, and offset. The description adds only marginal meaning (award words or program id 'narrow' results). Baseline 3 is appropriate when the schema does the heavy lifting.

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+resource (find the checklists an institution publishes) and even defines what a checklist is ('the generic itinerary of requirements for an award'). It also distinguishes itself from the one-record sibling by saying forms 'come from the one-record get, never from a list.' The question phrasing and dense asides slightly blunt the front-loaded clarity.

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?

It implies when to use narrowing parameters ('Optional award words or a program id narrow them; pass one to get_checklist') and routes agents to get_checklist for full form detail. However, the guidance is embedded in a run-on sentence, no explicit when-not conditions are given, and it doesn't state how it relates to compare_program_checklists or other checklist-adjacent siblings.

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