hcl_list_devices

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

The annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so safety is fully covered. The description adds that results carry 'file evidence and firmware boundaries', which is useful content context, but says nothing about scope, filtering, or ordering beyond that.

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?

A single front-loaded sentence with no filler. The trailing phrase 'with file evidence and firmware boundaries' is slightly opaque but is the only place value beyond the schema is conveyed.

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?

An output schema exists so return values need no explanation, and the zero-parameter read-only nature keeps demands low. However, with 51 sibling tools and several overlapping list/detail tools, the description should have clarified what 'model defaults' means and how this differs from hcl_get_device_details.

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 tool takes zero parameters, and the empty schema is self-explanatory, so there is nothing for the description to disambiguate. Baseline 4 applies; the description neither helps nor misleads here.

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 verb 'List' plus the resource 'installed HCL model defaults' is specific enough to be actionable, but the phrasing drifts from the tool name (devices vs. model defaults), leaving it unclear whether this enumerates discovered devices, model definitions, or default settings. It does not distinguish itself from the nearby hcl_get_device_details or the other hcl_list_* siblings.

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?

There is no statement of when to call this instead of hcl_get_device_details, hcl_list_projects, or hcl_list_templates, and no preconditions or exclusions are given. The agent must infer the usage context from the tool name alone.

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