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

No annotations are provided, so the description carries full behavioral transparency. It discloses that this is a mutating operation, that it optionally regenerates the activity plan, that activity regeneration preserves evolved activities by default, that regenerated activities must name a Key Result, and that the operation is sensitive/provision. This is usefulerly behavioral tone. It doesn't explicitly state rollback/reversibility, but it explains planning and side effects meaningfully.

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 leads with the primary action and a compact scope list, then gives the when to use, then the approval caveat at the end. It front-load the purpose, contains no wast, and the long bracket note is still relevant. It is not perfectly acousisic, but it is easily scanable.

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?

It includes what is updated, when to use it, optional behavior details, the special default for activity plans, the KR rule, and a notible process (sensitive-tier approval) that is not in structred fields. The main gap is that it doesn't mention the output format, but with no output schema and a strong description, this weighs more minor.

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 percent and the schema already describes all four parameters in detail, including how to find agent IDs and what companyId must be.a. The description repeats 'updates ... optionally activity plans' and adds no essential parameter guidance beyond the schema. Baseline 3 is appropriate.

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 is clear: 'Regenerate an agent's JD' is a specific verb+resource, and it enumerates the parts that are updated: mission, expertise, guardrails, success metrics, and planned activities. It also distinguishes who it works for, hired agents and Linnet, from generic agent tools. It does not fight an explicit sibling contrast, but the core purpose is unambiguous.

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 explicitly names when to use the tool: when the company has evolved, when an agent needs knowack, or when the user wants to refine direction. It adds an operational condition around sensitive approval. It does not provide negative guidance or alternatives, but it gives enough context for an agent to identify the primary triggering situation.

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