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

No annotations are provided, so the description carries full burden. It discloses that it automatically gets the correct issue, that no parameters are needed for current articles, and returns titles with URLs. It also explains the 2-month offset. It does not mention permissions, rate limits, or side effects, but those are not likely required.

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 description is front-loaded with 'STEP 1' and key purpose, then provides necessary context. It is informative without being overly verbose, though it could be slightly tightened.

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?

Given the 4 parameters and no output schema, the description is complete enough for the primary use case (current articles). It does not cover advanced usage with non-default parameters, but that is secondary. The explanation of the timing offset adds necessary context.

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 all parameters. The description adds practical context like default behavior and the timing offset, but does not significantly add meaning beyond the schema. Baseline 3 is appropriate.

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 clearly states it gets JW.org Watchtower study articles and returns article titles with RTF download URLs. It distinguishes from siblings by specifying it's for current/this week's Watchtower content and should be used FIRST.

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 description explicitly states when to use this tool (for current/this week's Watchtower content) and advises to use it FIRST without parameters. It also explains the timing offset. However, it does not provide guidance on when not to use it or alternatives for other editions.

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