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

Goes well beyond the annotations by disclosing what gets created (agent accessKey and a secret owner management link), a rate limit (two per daily network cohort), and two important behavioral constraints (hand the link to the owner, never change contribution settings yourself) plus the default that automatic sharing starts OFF.

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?

Dense and front-loaded: the core action and its quota come first, then the outputs, then the operational cautions. Every sentence carries information, though the telegraphic style takes a second read.

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 zero-param provisioning tool with no output schema, the description covers what is produced (keys, management link), the sharing default, and the caller's responsibilities. Minor ambiguity remains around what 'compact reads' actually are and how they are consumed.

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 tool takes zero parameters, so the baseline is 4; the description correctly needs no per-parameter detail and adds no misleading signature information.

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?

States a clear verb+resource ('Start 10 compact reads' via a trial) and is distinguishable from siblings like read_research and report_reuse. The phrase 'compact reads' is somewhat jargon-y, but the intent is legible.

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?

Gives use conditions and limits explicitly: no account or report required, two trials per daily network cohort, and to reuse existing keys. It does not directly name a sibling alternative, but the prerequisites are clear.

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