whoami

Read-onlyIdempotent

Unified Dutify whoami: fresh credential/workspace discovery. Does not require a selected workspace or reserve quota.

Tool call template

This tool declares no required parameters. Add optional parameters from the input schema as needed.

{
  "id": 1,
  "jsonrpc": "2.0",
  "method": "tools/call",
  "params": {
    "arguments": {},
    "name": "whoami"
  }
}

Input Schema

Name	Required	Description	Default
`account`	No	Multi-account auth only: name of the account from X-Dutify-Accounts to use for this call. Ignored in single-account mode (X-API-Key header). When multiple accounts are configured and this is omitted, the call fails with ACCOUNT_REQUIRED listing the available names. list_accounts never requires a selection.
`workspace`	No	Workspace identifier or exact name for this call. Overrides the configured workspace. For personal keys, discover candidates with list_workspaces and select explicitly. Does not change other calls or expand a workspace key's access.

Behavior3/5

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

Annotations already establish read-only, idempotent, and non-destructive behavior. The description adds that it requires no selected workspace and does not reserve quota, which is useful beyond annotations, but it does not describe return shape or discovery failure modes.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two short, front-loaded sentences with no wasted text. The core purpose comes first and the workspace/quota caveat follows immediately.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple read-only discovery tool with full parameter descriptions and annotations, the description is nearly complete. It could say more about what the discovery returns, but the complexity is low and no output schema is expected.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 100% description coverage for both optional parameters, so the heavy lifting is already done in structured data. The description adds no parameter-specific syntax or selection guidance, making the baseline 3 appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description identifies a concrete discovery operation: "fresh credential/workspace discovery" via `whoami`. It is clear enough to distinguish from most task tools, but it does not explicitly contrast with close siblings such as `list_accounts`, `list_workspaces`, or `find_my_workspace`.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It provides a usage context by saying no selected workspace or quota reservation is required, which implies it is useful in unconfigured or discovery scenarios. However, it does not explicitly state when to use this tool instead of `list_accounts`, `list_workspaces`, or `find_my_workspace`.

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