reqsign_generate_aws

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

With no annotations, the description must disclose behavior and side effects, but it only restates the core action. It does not say whether this writes files, returns a signature, uses the api_key, or has any other operational effect.

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 one-line description is free of filler and front-loads the main purpose, so it is concise. However, it is so skeletal that it provides little structure beyond a phrase, making it minimal rather than a well-shaped tool definition.

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 annotations, so the description must carry the full context. It fails to explain the output, credential requirements, or relationship to a project directory, leaving an agent without enough information to invoke the tool correctly.

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 coverage is only 50%; directory is described by the schema, but api_key is undocumented and the description adds no meaning to either parameter. An agent cannot tell what api_key represents or how it is used in AWS Signature V4 generation.

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 uses a specific verb ('Generate') and a precise resource ('AWS Signature V4'), making the tool's purpose immediately clear. It also differentiates from adjacent tools like reqsign_generate_hmac by naming the exact signing scheme, even without mentioning that sibling 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?

No guidance is given about when to choose this tool over reqsign_generate_hmac or reqsign_add_verification. The only context is the resource name, which implies AWS use but does not state prerequisites, alternatives, or exclusions.

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