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

With no annotations, the description carries full behavioral burden and discloses solid context: the server adds the token address signature, the 3-minute validity window, and a default 60-second confirmation wait. It still omits failure/rejection behavior and idempotency, so it is strong but not complete.

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?

Three tight sentences, front-loaded with the purpose, followed by constraints and the confirmation default. No filler, though the second sentence packs two distinct facts (provenance and signature) without separating their implications.

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 mutation tool with no annotations and no output schema, the description covers key operational constraints but leaves three undocumented parameters and the response/failure surface unexplained. Adequate to call, but an agent lacks guidance on error handling and parameter values.

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% for all 3 parameters, so the description must compensate but largely does not: transaction_base64 and last_valid_block_height receive no explanation. Only wait_for_confirmation is partially addressed via the 'waits up to 60 seconds by default' sentence.

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: relaying a signed launch transaction, scoped to 'launch' which differentiates it from claim-path siblings like prepare_claim_transaction and report_claim_sent. However, it does not explicitly name which sibling produces the transaction or contrast itself against the claim submission flow, leaving some ambiguity.

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 3-minute acceptance window for transactions 'prepared by Paid2Call' implies a prerequisite step (prepare/sign) and bounds when this tool is valid, which is genuinely useful. But it never names the alternative or prerequisite tool, nor states what to do when the window has expired, so usage is only implied.

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