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

Goes well beyond the annotations (write, non-destructive, non-idempotent). It discloses that keyless reports are filed under a single reused per-source anonymous account, displayed as 'unverified', and excluded from scoring — behavior an agent could not infer from the schema. It also adds a data-handling constraint ('no personal data in notes').

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 key point (no download/registration, failures count) is front-loaded, but the single dense paragraph chains many semicolon-joined clauses and repeats 'Optional' from the schema. Several attribution details could be tightened without losing meaning.

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 write tool with no output schema, the description covers the important unknowns: anonymity, account reuse, verification labeling, and score impact. It does not state what the call actually returns (e.g., a report id or the new API key on the handle path), which is the main remaining gap.

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, but the description adds real meaning: model/client/tool_versions are rendering hints shown as 'Tested on', handle+signature yield an API key in the same call, and notes must stay short and free of personal data. It does not clarify the api_key-vs-header precedence beyond noting both are equivalent.

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 specific action and resource: submit the outcome of a recipe you tried, in one call, without registration. It clearly distinguishes itself from register_bot (which it explicitly recommends doing first), but it never differentiates itself from the sibling report_result, which is presumably the keyed variant. An agent can grasp the intent but may hesitate between quick_report and report_result.

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?

Strong conditional guidance: send an API key if you have one, otherwise the report is anonymous and unverified and does not move the score; prefer register_bot(handle, signature) first for attribution. It also explains the optional handle+signature path for an instant key. It stops short of naming the sibling report_result or stating when keyless reporting is preferable to registering.

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