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

Annotations already declare readOnly, idempotent, non-destructive, and closed-world, so the safety profile is covered. The description adds real value beyond that by enumerating the returned sections (The Gap, Left Said, Right Said, The Record, Consensus Watch, Sunday-only Claim of the Week and Democracy Watch) and by flagging the data-freshness caveat that facts are as of the edition date.

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 core addressing rule and default are front-loaded in the first clause, with content scope and freshness caveat following. The long run-on section enumeration is dense but each item carries information, so little is wasted.

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 correctly takes on the return-shape burden and describes the edition's contents and the Sunday variation. Only minor gaps remain, such as error behavior for an unknown or malformed id.

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 schema already documents both the id forms and the newest-edition default. The description's examples ("042", "42", "P001", URL) largely restate that, adding little semantic meaning beyond the structured field, so baseline 3 applies.

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?

States a specific verb and resource ("get one Straight Record edition in full") plus the exact addressing modes (id, alternate id forms, or URL) and the no-arg default. This clearly distinguishes it from siblings like get_good_day_edition, latest, and search without requiring the schema to be opened.

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?

"Use for reading every story's..." gives explicit usage context, and the default-to-newest behavior is stated. It stops short of naming when to prefer siblings such as latest, fetch, or search, so there is no explicit when-not guidance.

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