check_for_updates

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

No annotations provided. Description discloses what is returned but omits details on network usage, potential delays, or error handling. Adequate for a simple check, but could be more transparent.

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 concise sentences: first states function and outputs, second gives usage guidance. No wasted words.

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?

For a simple no-parameter tool, description covers purpose, return values, and when to call. Lacks mention of connectivity prerequisites, but sufficient for most cases.

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?

Input schema has zero parameters, so no additional description needed. The description adds no parameter info, but schema coverage is 100% by absence.

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 the tool checks for memoryweb updates, specifies return values (current version, latest, instructions), and gives a direct usage example. It distinguishes from sibling tools which are about memory/domain operations.

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?

Explicitly says 'Call this when the user asks if memoryweb is up to date,' providing clear context. No mention of when not to use, but no obvious alternative exists among siblings.

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