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

Annotations already declare the key profile: readOnlyHint=false, destructiveHint=false, idempotentHint=false, openWorldHint=true, so the agent knows this is a non-destructive but non-repeatable outbound submission. The description reinforces this by calling it a support request, but adds nothing about what actually happens after submission—whether a human reviews it, how long approval takes, or whether the whitelist applies immediately. For an external-world escalation tool those are the behaviors that matter most, and they are absent.

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?

A single sentence that front-loads the action and packs the qualifying audience into a compact list with no filler. It could have used a second short sentence for post-submission behavior without becoming bloated.

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?

No output schema exists, so return values are entirely on the description, and it does not say whether the call yields a ticket ID, an approval status, or an immediate whitelist change. Combined with the lack of any guidance on the two defaulted parameters, the definition is thin for a mutating, externally-routed request tool, even if an agent can still invoke it correctly from the schema alone.

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 60%, so baseline behavior is middling. The description gives useful range context for requested_daily_limit ('25–100 compiles/day') that the schema does not, but says nothing about client_ip (defaulted to 127.0.0.1) or how the three required identity fields relate to the request. Half the parameters carry real meaning only from the schema.

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 names a concrete action (submit a Support Whitelist Request) and its outcome (higher daily compilation write limits) and enumerates who qualifies: engineering teams, corporate NAT IPs, PCB layout agencies. That is enough to distinguish it from compile-and-DRM siblings, though it never explicitly contrasts itself with any of them, so it stops short of a 5.

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 qualifying condition is implied in the phrasing 'needs higher daily compilation write limits (e.g. 25–100 compiles/day)', which tells an agent this is an escalation path rather than a per-compile action. However there is no explicit 'use when/do not use when' statement, no mention of prerequisites (whether an existing account or prior denial is required), and no alternative named for teams whose limits are already sufficient.

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