append_dashboard_view

Add a new view to a Home Assistant Lovelace dashboard by passing its URL path and view definition, so you can create tabs with cards, icons, and titles.

A view looks like:: {"title": "Moestuin", "path": "moestuin", "icon": "mdi:sprout", "cards": [ ... ]}

TDQS

C2.9/5.0
Behavior2/5

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

With no annotations, the description carries the full behavioral burden. It only signals a mutation via 'append' and shows a sample view shape; it says nothing about permissions, ordering/index behavior, what happens to existing views, or failure modes.

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?

Front-loads the core action in the first sentence and follows with a single illustrative example; nothing is wasted. The '::' punctuation is awkward but does not impede comprehension.

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

Completeness2/5

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

A mutation tool with no annotations, no output schema, and 0% parameter description coverage needs more than this. The view example is helpful, but url_path, return behavior, and error handling are all absent.

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 0%, so the schema does not help. The description partially compensates by giving a concrete example of the free-form 'view' object (title/path/icon/cards), but it gives no explanation of 'url_path' at all, leaving one of two required parameters fully opaque.

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?

States a specific verb ('append'), resource ('view'), and target ('dashboard'), so an agent can immediately grasp the operation. It implicitly differs from siblings like replace_dashboard_view and delete_dashboard_view via the verb, but never names those alternatives explicitly.

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

Usage Guidelines2/5

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

The verb 'append' weakly implies a use case (adding rather than replacing a view), but there is no explicit when-to-use guidance, no mention of prerequisites, and no comparison to replace_dashboard_view, set_dashboard_config, or create_dashboard.

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