provider_get_theme_file

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

Annotations already declare readOnly, idempotent, openWorld and non-destructive, so the safety profile is covered. The description adds genuinely new behavioral context: the resource needs no authentication and no Accept header with an api version, which an agent could not infer from annotations or schema.

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?

Two short sentences, front-loaded with the action and scope. The trailing raw GET path largely duplicates the annotation title, making it a small redundancy rather than a value-add.

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?

No output schema exists, and the description never says what is returned - raw file bytes, JSON, or a 404 behavior when the file is absent. For a file-fetch tool with zero output documentation, that is a meaningful gap, though the auth exemption note helps.

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?

Schema description coverage is 100%, so both parameters are already documented as path components. The description only restates that the file is identified by theme id/path and adds no format, encoding, or naming-convention detail beyond the schema.

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?

States a specific verb and resource: load a theme file identified by folder and file name. This is clearly distinguishable from siblings like provider_get_theme_flavor_file and provider_get_active_theme, though those alternatives are not named explicitly.

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?

Implied usage only: fetch a theme file when you know its root folder and file name. There is no explicit when-to-use guidance, no mention of how it differs from provider_get_active_theme or provider_get_theme_flavor_file, and no note on what to do when the file does not exist.

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