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

With no annotations, the description carries the behavioral burden and does well: it discloses normalisation, a typed allow/review/deny gate, authority defaults, and that the response includes exact on-chain cost in SOL and USD. It stops short of explicitly stating side effects, rate limits, or how review/deny outcomes are surfaced.

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 purpose is front-loaded and the text is compact. There is minor redundancy between 'Free.' and 'it costs nothing', but otherwise every sentence contributes useful context.

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 an eight-parameter planning tool with no output schema, the description gives enough to select and invoke it correctly: purpose, sequencing, validation gate, authority defaults, and cost output. More detail on the exact response shape and gate outcomes would make it fully 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?

Schema description coverage is 100%, so the schema already documents all eight parameters thoroughly, including defaults and enums. The description reinforces a few defaults such as mint revocation and freeze authority, but adds little semantic detail beyond what the schema provides.

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: validate a Solana token launch. It distinguishes itself from the build step with 'before building it', so an agent can separate planning from transaction construction without opening schemas.

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 description explicitly says 'Use this first' and explains why: it is free and catches mistakes before signing. It implies the build tool should come later, but does not explicitly name the alternative sibling tool or state when not to use this one.

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