Company Considerations by Market

get_structuring_playbook

Read-onlyIdempotent

General considerations by customer market (USA, EU, Switzerland, Asia, Middle East), what a holding company does and does not do, a checklist of obligations and questions to take to a licensed adviser. Tax follows the owner. No structure is recommended. General information, not advice.

TDQS

A3.6/5.0

Behavior4/5

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

The annotations already declare readOnlyHint, idempotentHint, non-destructive and closed-world, so safety needs no restating. The description adds real behavioral framing that the annotations do not: the output is deliberately advisory-free ('No structure is recommended'), carries a not-advice disclaimer, and is scoped to general considerations — which tells an agent not to present its content as a recommendation.

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

Conciseness3/5

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

It is short and front-loads the resource, but the middle sentence is a comma-spliced run-on inventory ('what a holding company does and does not do, a checklist of obligations and questions to take to a licensed adviser') that reads as a table of contents rather than a statement of purpose. No sentence is wasteful, but the telegraphic list style costs clarity.

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?

An output schema exists, so return structure need not be explained, and all three parameters are fully documented in the schema with annotations covering the safety profile. What is missing is routing context — how this differs from get_structuring_roster and when an agent should escalate from this general playbook to plan_global_setup or a consultation.

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 coverage is 100%, so the baseline is 3. The description does add a small amount of meaning by expanding the market codes (ch to Switzerland, mea to Middle East) and by linking the holding parameter to the holding-layer discussion. The archetype parameter (solo-lean | scaleup | enterprise) is not addressed at all, so the addition is partial.

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 enumerates what the playbook contains — market-by-market considerations, what a holding company does and does not do, and an obligations checklist — so an agent can tell it is a general-orientation reference rather than a specific computation. It never names or distinguishes itself from the closely named sibling get_structuring_roster or from plan_global_setup, so the boundary remains inferential.

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?

Usage is only implied: the closing 'General information, not advice' plus 'No structure is recommended' signal this is the orientation step before a licensed adviser or a concrete plan. There is no explicit when-to-use statement and no mention of the alternative tools (get_structuring_roster, plan_global_setup, compare_formation) an agent should pick instead for roster detail or an actual recommended structure.

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