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

Annotations already mark this as destructive and not read-only, while the description adds context by naming archive and re-prioritize as example operations. It does not describe the nature of the destructive effects or whether changes are reversible, but it does not contradict the annotations.

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 two sentences with the core behavior front-loaded and an actionable prerequisite included in the second sentence. Every part earns its place; there is no redundant or filler content.

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?

The essential batch semantics and required pre-read skill are covered, and annotations already supply safety and idempotency context. It does not discuss return values or partial-failure behavior, but the schema and annotations cover most operational needs.

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?

The schema already provides descriptions for archived, priority, and archivedReason (75% coverage), and the description's examples map onto those same parameters. The description adds no new parameter-level semantics beyond what the schema already exposes.

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 precise verb and resource: 'Update multiple topics at once.' It also gives concrete example uses ('archive or re-prioritize a set of topics') and the plural scope clearly distinguishes it from the sibling update_topic tool.

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 provides a clear usage context by indicating batch operation over multiple topics and instructs the agent to read the 'write-tools' skill before the first call. It does not explicitly name alternatives or state when not to use it, so it falls short of a 5.

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