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

With no annotations, the description carries the full burden, and it discloses the most important trait: this is a passive information lookup and the actual signup/email confirmation happens on the user's side, not through the tool. It doesn't say whether the answer is static or time-sensitive (e.g. whether the waitlist is open), which is the remaining behavioral unknown.

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?

Two short sentences: the first says what the answer contains, the second says what to do with it. No filler, and the content statement is front-loaded.

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 no-parameter, no-annotation informational tool with no output schema, this covers what is returned (join link plus benefits) and the agent's role in presenting it. A little more on the shape of the answer or whether the waitlist status can change would make it complete.

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?

The tool takes zero parameters, so the baseline of 4 applies. The description correctly implies no input is needed and none of its text invents parameter concepts.

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 the content precisely: how a person joins the Oddi Forge waitlist and what they get. This is topically distinct from the sibling getters (faq, news, project facts, team). It lacks an explicit verb like 'Returns' or 'Get', so a reader has to infer it is an informational lookup rather than an action.

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?

'Share the link with the user' gives clear operational guidance on what to do with the result, and 'the user signs up and confirms their email themselves' draws a hard boundary on what the agent must not attempt. It does not name when to prefer a sibling (e.g. get_faq for related questions), so routing guidance is only implied by topic.

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