authenticate_sandbox

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

The annotations already disclose that this is open-world, non-read-only, and non-idempotent. The description adds useful behavior beyond that: it hits the UAT login endpoint, reads local KOUNT_CLIENT_ID and KOUNT_API_KEY configuration, caches the bearer token, never returns credential values, and does not call order APIs. It omits cache duration or token expiry behavior, but the core side effects and credential handling are clear.

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 definition is compact and front-loads the main action and external endpoint. Most clauses earn their place by adding endpoint, credential-source, caching, return-safety, or scope information, though the final fragment is slightly terse and could be structured more cleanly.

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 zero-parameter authentication utility with no output schema, the description covers the external endpoint, environment-based credentials, caching behavior, and the important guarantee that secrets are not returned. It lacks details about token/cache lifetime and exactly what a successful non-secret response contains, which keeps it from being fully complete.

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?

The tool has zero parameters, so the schema baseline is 4. The description reinforces this with 'No arguments,' which helps an agent avoid inventing inputs for an authentication call.

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 states a specific verb and resource: obtain and cache a bearer token from the Equifax UAT token endpoint. It clearly distinguishes this authentication utility from sibling tools focused on readiness checks, schemas, validation, examples, and error explanations.

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?

Usage is implied: call this to obtain and cache auth credentials, and it explicitly says no order API calls are made. However, it does not state when in the workflow to call it, whether it must precede specific sibling tools, or what alternatives exist if authentication is already cached.

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