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

No annotations exist, so the description carries the full load, and it does disclose the single most important behavioral trait: it is a dry run unless commit is set, so the safe default is preview. It also discloses the blocking precondition. It stops short of saying what a dry run returns, whether a real submission is reversible, or what happens after submission, which matters for a mutation of this weight.

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?

Four short sentences ordered by what → precondition → content rule → safety default, with no filler. The 'DRY-RUN BY DEFAULT' fragment is deliberately front-loaded as the last and most operationally important signal.

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 15-parameter mutation with no annotations and no output schema, it covers purpose, gating, content sourcing, and dry-run safety — everything needed to avoid a wrong call. What's missing is post-call behavior: what the dry run echoes back, whether submission is irreversible, and whether re-submission after rejection is allowed.

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 100%, so the baseline is 3; the description earns a point above it by constraining how the free-text answer parameters must be sourced ('the developer's own words about their testing — never invent them'), which the schema cannot express. It also reinforces the commit parameter's default behavior at the description level rather than leaving it buried.

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 specific verb and resource ('Submit the production-access application questionnaire') scoped to 'a personal developer account', which no sibling tool covers. The prerequisite reference to setup_closed_testing and get_setup_state lets an agent place it precisely in the workflow without opening any schema.

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?

Explicit gating condition ('Only possible once the closed-testing tester/day requirement is met') plus named tools to verify that condition before calling. It also sets a content rule — answers must be the developer's own words, never invented — which is usage guidance an agent would otherwise get wrong.

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