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

Annotations declare readOnlyHint=false, openWorldHint=true, and destructiveHint=false, so the safety profile is partially covered. However, the description adds almost nothing beyond that: it does not say whether this kicks off an asynchronous job that must be polled via glowups_get, what idempotency_key does on retry, or what max_awt and quote_only imply (latency/cost controls). "Starts directly" hints at initiation but never confirms it.

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?

It is a single short fragment with no filler, so nothing is wasted, but the semicolon structure conveys two vague clauses rather than a front-loaded statement of action and scope. Brevity here comes at the cost of specification rather than through efficiency.

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?

This is a complex tool with 9 parameters, a nested object, enums, and no output schema, and the description does not cover initiation semantics, polling/return expectations, or parameter meaning. Given the low schema coverage and only partial annotations, the definition leaves an agent without enough information to invoke it correctly on the first try.

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 description coverage is only 11% across 9 parameters, including a nested `revise` object and a deprecated `output` enum, so the description carries the burden of compensation and does not meet it. The phrase "from a website or idea" loosely maps to website_url and direction values, but direction enums, quote_only, max_awt, and idempotency_key are entirely unexplained.

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?

"GlowUp report from a website or idea; starts directly" identifies the resource (a GlowUp report) and implies job initiation, but the verb is oblique and "starts directly" is never explained. It does not distinguish this tool from nearby siblings such as glowups_get, glowup_attach, or glowup_build_open, so an agent cannot tell which one to pick from the description alone.

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?

There is no when-to-use or when-not-to-use guidance and no alternative named. The description also never mentions the revise flow exposed by the nested `revise` parameter, so an agent has no signal that this tool can iterate on an existing GlowUp rather than only create one.

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