update_meta_download

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

No annotations are provided, so the description carries the full burden. It discloses the action and the 'in-progress' constraint, but doesn't explain what happens if the export isn't in-progress, whether the change is reversible, or if it triggers emails. The term 'toggle' also adds ambiguity about whether it flips or sets the value.

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?

One sentence, front-loaded with a specific verb, and no redundant information. Every word earns its place.

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 tool is a simple setter, and the description plus schema cover essential inputs and the action. The 'in-progress' qualifier and guid reference are enough for basic use, but the toggle/set ambiguity and lack of behavior details slightly reduce completeness.

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 coverage is 50% with only guid described. The description compensates by identifying send_email as the flag to toggle, and the schema already documents guid via create_meta_download reference. With only two parameters, this is sufficient.

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 uses the specific verb 'Toggle' and identifies the resource 'send_email flag' on a 'metadata export', which clearly distinguishes it from siblings like create_meta_download. However, 'toggle' is slightly imprecise because the schema requires a boolean value, implying the tool sets the flag to the provided value rather than flipping the current state.

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 implies this tool updates an existing metadata export's email preference, and the schema's guid description references create_meta_download. It offers clear context for when to use it (on an in-progress export), but lacks explicit exclusions or alternative tool references.

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