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

With no annotations provided, the description carries the burden of behavioral disclosure. It usefully reveals memory-bounded chunking behavior and the 0.01 USDC cost, but it does not disclose output format, error behavior, or how the payment signature interacts with execution. This is partial transparency, not full.

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 a single tightly written sentence followed by a parenthetical cost note. Every word earns its place, the core capability is front-loaded, and there is no filler or repetition of the tool name.

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?

There is no output schema and no description of the return shape, and the input schema's payload field is generic boilerplate. The phrase 'across byte streams' is not reconciled with the JSON-string payload, so an agent cannot confidently construct the input or predict the result. This is a significant gap for a tool with no annotations.

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 baseline is 3. The description adds the useful context of byte streams and multi-algorithm computation, but it does not clarify how the string payload should encode the input data or how paymentSignature relates to the stated cost. It provides no meaningful parameter-level example or structure.

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 names the exact verb ('Computes'), the precise resource (MD5, SHA-1, SHA-256, SHA-512 checksums), and a distinguishing trait (simultaneously across byte streams with memory-bounded chunking). This clearly separates it from sibling tools and tells an agent exactly what operation will be performed.

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 implies when to use the tool: when multiple checksums are needed in a single pass, especially for large streams needing memory-bounded chunking. However, it never explicitly states when not to use it or points to any alternative tool, leaving the agent to infer selection criteria.

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