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

Annotations already declare non-read-only, open-world, non-idempotent, non-destructive behavior, so the bar is lower. The description adds real value by disclosing that the email, first name, and Idea Read are transmitted to a third party (Ruzora) and that the report arrives by email; it could still note that a repeated call re-sends/re-runs rather than returning the same result.

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?

Front-loaded and short, but the third sentence ('Sends the email, first name and Idea Read given here to Ruzora, which uses them to send the report') largely repeats the first sentence's content, so not every sentence fully earns its place.

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?

With no output schema, the description usefully explains what comes back (a keep-going/one-developer/small-team verdict) and how (PDF by email), and it names all three inputs. It is essentially complete for a 3-param submission tool, missing only idempotency/resubmission behavior.

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 3 is the baseline, but the description adds meaning: it clarifies the email is only a delivery address ('Any email works'), that first_name is used in the report, and that idea_read_markdown is the full interview output. That is modest but genuine value beyond the schema text.

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 — send the AI-written Idea Read to Ruzora for a verdict plus PDF — and names the sibling that produces the input (start_honest_read), so an agent can distinguish it from the other 30+ tools. The verdict categories are even enumerated.

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?

It clearly places the tool after start_honest_read ('the Idea Read your AI wrote') and notes 'Any email works,' which resolves a likely prerequisite worry. It stops short of explicit when-not-to-use guidance or warning against resubmitting an already-submitted read.

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