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

Annotations already establish this is a safe, read-only operation against an open world, so the description's burden is lighter. It usefully discloses the return shape (signed flag, then coin address and links), but says nothing about behavior before signing, error cases, or latency.

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?

One front-loaded sentence covering both the primary answer and the conditional payload, with no filler. The trailing clause 'once it has' is slightly clipped but not wasteful.

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 must carry return semantics, and it does name the key fields returned. However, it leaves out the unsigned/error path and treats the sole input as self-evident, which is thin for a status-lookup tool.

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 0% and the description never mentions draft_id, so the only information an agent has is the parameter name and its string type. It does not explain what a draft is, where the id comes from, or what happens with an invalid id.

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 resource (a planned launch) and what is reported about it (signed status, plus coin address and links once signed). It is clear enough to separate from plan_launch or get_coin, though it never names those siblings or their boundaries explicitly.

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 phrase 'planned launch' implies this is a follow-up to plan_launch, but there is no explicit when-to-use, no prerequisite statement (e.g., a draft_id must already exist), and no exclusion against alternatives like get_coin or list_coins.

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