AMZ Vault

Workforce: Check in

workforce_check_in

Check in with the AMZ Vault AI Workforce and receive the next worker packet. Execute the packet exactly as instructed, submit results with workforce_report, then call this again — loop until packets_remaining is 0, then give the user a short closing summary. Stage changes only (never confirm): workforce changes are approved by the owner in the AMZ Vault dashboard. The server decides all assignments and enforces a per-check-in budget so the workforce never exhausts the user's Claude usage. Optional departments (e.g. ["D1","D4"]) restricts this check-in to those departments' work - used by per-department scheduled tasks; omit to serve everything. Optional brands (brand names or connection ids) restricts it to those brands - used when brands run on different daily start times.

Tool call template

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

    "name": "workforce_check_in"
  }
}

Input Schema

Name	Required	Description	Default
`brands`	No	Optional brand names (or seller connection ids) to restrict this check-in to - other brands' queues wait for their own scheduled task.
`departments`	No	Optional department codes to restrict this check-in to (from the packet catalog, e.g. ["D1","D4"]).

Behavior5/5

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

Adds substantial behavioral context beyond the annotations: the tool stages but never confirms, the server controls assignments and budget, and the check-in is part of a repeatable loop. There is no contradiction with readOnlyHint=false or destructiveHint=false.

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

Conciseness4/5

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

The core protocol is front-loaded and every sentence carries operational meaning, but the final two sentences on departments and brands are long, multi-clause, and could be structured more cleanly. Overall still dense and useful.

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

Completeness5/5

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

For a stateful loop tool with no output schema, the description covers the full lifecycle: what to do with the packet, how to report, when to stop, and safety constraints. The 'worker packet' concept is treated as shared vocabulary and is sufficient given the sibling workforce_report.

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

Parameters4/5

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

The schema already covers both parameters at 100%, and the description adds useful usage context: departments map to scheduled tasks, brands relate to differing daily start times, and omitting filters serves everything. This goes beyond the schema but is not exhaustive.

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

Purpose5/5

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

Opens with a specific verb and resource: 'Check in with the AMZ Vault AI Workforce and receive the next worker packet.' This clearly differentiates the tool from reporting/status siblings like workforce_report and workforce_status by framing it as the entry point to a work loop.

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

Usage Guidelines5/5

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

Explicitly describes the loop protocol: execute the packet, submit results with workforce_report, call again until packets_remaining is 0, then summarize. It also states when department/brand filters should be used and that only staging is allowed, never confirmation.

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