Put Paramset

put_paramset

DestructiveIdempotent

Write multiple HomeMatic device parameters in one operation, such as a thermostat weekly profile. Provide the channel address and key-value pairs to update configuration directly.

Instructions

Write multiple parameters at once (e.g. thermostat weekly profile). Interface is auto-resolved from address.

Tool call template

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

Input Schema

Name	Required	Description
`set`	Yes	Key-value pairs to write (e.g. {TEMPERATURE_WINDOW_OPEN: 5.0})
`address`	Yes	Channel address
`confirm`	No	Set true to authorize this write against a protected CCU target (e.g. prod). Unlocks writes to that target for the rest of the session.
`interface`	No	Interface name override
`paramsetKey`	Yes	Paramset to write

A4/5.0

Behavior3/5

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

With destructiveHint and idempotentHint already annotated, the description need not restate safety. It adds one useful behavior (interface auto-resolution from address), but does not describe write effects on existing values or the confirm/protected-target flow, leaving some behavioral context to the schema.

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?

Two sentences with no filler. The main action and an example come first, followed by the interface behavior; every clause contributes.

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?

Given the rich 100%-covered schema and the destructive/idempotent annotations, the description plus schema are sufficient to invoke the tool correctly for common cases. It lacks an explicit alternative routing and return-value note, but these are minor for this write tool.

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 adds a small amount (interface auto-resolution and an example for set), but most parameter meaning is already in the schema; it does not materially compensate for any gap.

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 uses a specific verb ('Write'), resource ('multiple parameters'/paramset), and provides a concrete example (thermostat weekly profile). This clearly distinguishes it from siblings like set_value (single-value write) and get_paramset (read).

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

Usage Guidelines4/5

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

'Write multiple parameters at once' gives clear context for when to use this tool instead of a single-value write, and the example adds a realistic use case. It does not explicitly name alternatives or exclusions, so it stops short of a 5.

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