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

Annotations already declare readOnlyHint, idempotentHint, and openWorldHint=false, so the safety profile is covered. The description adds that the guidance is 'current' (i.e., live content that may change) and enumerates the topics covered, but says nothing about response shape, caching, or whether content varies by locale.

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?

Two sentences, zero filler, with the core purpose front-loaded before the parameter selection hint. Every clause carries information.

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?

No output schema exists, and the description does enumerate what the returned guidance covers (paper dimensions, print files, printing methods), which is enough for an agent to know what it gets back. The only real gap is the silent locale parameter.

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 has to carry the parameter burden. It does map the paperSize enum to human labels ('US Letter, A4, Newspaper Club digital tabloid'), which is genuinely useful, but the locale parameter (en/fr) — which presumably changes the language of the guidance — is never mentioned.

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: 'Read current My Wed Paper guidance' scoped to paper dimensions, print files, and home/professional printing. It is clearly distinct from its siblings (template search, crossword generation) by domain, though it never explicitly contrasts itself with them.

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 second sentence ('Select US Letter, A4, or Newspaper Club digital tabloid') steers the invocation choice at the parameter level, but there is no guidance on when to call this versus anything else, no prerequisites, and no exclusions. Usage is implied rather than stated.

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