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

Annotations already establish that this is a non-read-only, non-destructive, open-world write operation. The description adds useful behavioral context—confirmation is required and a minimum interval applies—but leaves other important behavior such as idempotency handling and what exactly is modified unexplained.

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 short but fragmented and cryptic, especially 'pausing immediate, minimum15min.' Brevity here comes at the cost of clarity rather than being efficiently front-loaded.

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 10-parameter save tool with no output schema and no parameter descriptions, the definition is far from complete. It mentions confirmation and a minimum interval but omits the meaning of required fields like workspace and idempotency_key and the other schedule fields.

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 has 10 parameters with 0% description coverage, so the description must carry the burden. It does not name or explain any parameter, and vague phrases like 'capped' and 'minimum15min' do not map clearly to fields such as max_awt_per_run or cron.

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 verb and resource: 'Save capped recurring runs.' However, 'capped recurring runs' is jargon and the tool is not clearly identified as a schedule-save operation, so the purpose is only vaguely clear.

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 gives a prerequisite ('after MCP confirmation') and a constraint ('minimum15min'), which implies when the tool should be used. It does not compare against alternatives or explain when not to use it, so guidance is minimal but present.

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