textokit_dev_utils

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

No annotations are provided, so the description carries the full behavioral burden. It usefully discloses pricing (0.001 USDC per call) and the x402/Base wallet payment model, plus a free sample alternative, but it does not state whether operations are read-only, what errors or payment failures look like, or what the response format is.

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 two compact sentences. The operation list is front-loaded, and the pricing/payment note is important and efficiently stated. There is no wasted text.

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 multi-operation utility with six parameters and nine enum operations, the description covers the broad operation families and payment model but omits two enumerated operations and gives no per-operation behavioral detail. The schema fills most parameter gaps, but the absence of annotations or an output schema leaves the description somewhat incomplete.

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 each parameter, including enum values and defaults. The description adds only a high-level operation list and does not explain how parameters like `value`, `secret`, and `algorithm` behave per operation, so it meets the baseline rather than adding meaning beyond the schema.

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 specific operation families (hash, HMAC, JWT decode, UUID, base64, time zone) that map closely to the `op` enum, so an agent can tell what the tool does. It is not fully precise because it omits some supported operations like `url_parse` and `unix_to_iso`, and calls itself 'utilities', but the overall purpose is clear.

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 usage through the listed operations and points to `textokit_sample` as a free alternative. However, it does not explicitly say when to use this tool versus the sample or other siblings, nor does it describe selection conditions for individual operations.

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