hacs_install_hacs_repository

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

With no annotations and a brief description, the tool leaves critical behavioral details unclear: required permissions, side effects (e.g., downloading files), error handling, and reversibility. The description does not disclose that installation is a write operation.

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 is a single sentence of 11 words, achieving conciseness. However, it could include a bit more context without becoming verbose.

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?

For a simple install tool, the description misses key details: repo_id format, version constraints, prerequisites (e.g., HACS must be installed), and output/error behavior. The presence of an output schema is not leveraged in the description.

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?

The description adds meaning for the optional 'version' parameter (pinning), but provides no explanation for 'repo_id', which is required. Given 0% schema description coverage, the description should compensate but falls short.

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 clearly states the action (install), the resource (HACS repository), and the optional version pinning. It effectively differentiates from sibling tools like hacs_uninstall_hacs_repository and hacs_update_hacs_repository.

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?

No guidance on when to use this tool over alternatives such as hacs_add_custom_repository or hacs_update_hacs_repository. There is no mention of prerequisites or context for its use.

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