agenthold_register

Register an agent to obtain a unique session ID for managing shared resources in multi-agent workflows. Required before using other agenthold tools.

Instructions

Register yourself and receive a unique agent_id. IMPORTANT: You MUST call this once before using any other agenthold tool that requires an agent_id. Pass your name (e.g. 'editor-agent') and optionally the model you are running on (e.g. 'claude-sonnet-4-6'). The returned agent_id is your identity for this session — use it in all subsequent agenthold_claim and agenthold_release calls. Do not call this more than once per session.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

TDQS

A4.4/5.0
Behavior4/5

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

With no annotations provided, the description carries full burden and does well by explaining the session-based nature ('for this session'), the one-time requirement, and that the returned agent_id serves as identity for subsequent operations. It doesn't cover error conditions or rate limits, but provides solid behavioral context.

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?

Front-loaded with the core purpose, followed by critical usage instructions. Every sentence earns its place: registration purpose, prerequisite warning, parameter guidance, session identity explanation, and usage restriction. No wasted words.

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 registration tool with no annotations and no output schema, the description does well by explaining the session-based workflow, one-time requirement, and relationship to sibling tools. It could mention what happens on registration failure or the format of the returned agent_id, but covers the essential context.

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?

Schema description coverage is 100%, so the schema already fully documents both parameters. The description provides examples ('e.g. 'editor-agent'', 'e.g. 'claude-sonnet-4-6'') that match the schema descriptions, adding minimal value beyond what's already structured. Baseline 3 is appropriate.

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?

The description clearly states the specific action ('Register yourself'), the resource ('receive a unique agent_id'), and distinguishes this from sibling tools by explaining it's a prerequisite for other agenthold tools. It goes beyond just restating the name to explain the registration function.

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 states when to use ('call this once before using any other agenthold tool that requires an agent_id'), when not to use ('Do not call this more than once per session'), and mentions specific alternatives ('agenthold_claim and agenthold_release calls'). Provides clear sequencing guidance.

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