make_payment_txn

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

With no annotations provided, the description carries full burden for behavioral disclosure. 'Create a payment transaction' implies a write operation that likely requires authentication and network interaction, but the description doesn't mention these requirements. It doesn't disclose whether this actually submits the transaction or just constructs it, what happens on failure, or any rate limits. For a financial transaction tool with zero annotation coverage, this is a significant gap.

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 description is extremely concise at just three words. While it may be too brief for adequate tool understanding, it contains zero wasted words and is perfectly front-loaded. Every word directly contributes to stating the tool's purpose.

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 complex financial transaction tool with 10 parameters, no annotations, and no output schema, the description is severely inadequate. It doesn't explain what happens after creation (is it submitted? signed?), what the return value is, error conditions, authentication requirements, or network implications. The description fails to provide the contextual completeness needed for safe and effective use.

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 10 parameters thoroughly. The description adds no additional parameter semantics beyond what's in the schema. According to scoring rules, when schema coverage is high (>80%), the baseline is 3 even with no param info in the description, which applies here.

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?

The description 'Create a payment transaction' clearly states the verb ('Create') and resource ('payment transaction'), but it's vague about what this actually means in the Algorand context. It doesn't distinguish this from sibling tools like 'make_asset_transfer_txn' or other transaction creation tools, leaving ambiguity about when to use payment vs asset transfers.

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?

No guidance is provided about when to use this tool versus alternatives. With many sibling tools for different transaction types (asset transfers, app calls, keyreg, etc.), the description offers no context about when a payment transaction is appropriate versus other transaction types. It doesn't mention prerequisites like needing sender authentication or network connectivity.

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