fetch_config

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

No annotations are provided, so the description must fully disclose behavior. It mentions fetching and listing but does not clarify side effects (e.g., file overwrites, authentication requirements, error handling). The token parameter hints at auth, but description omits this.

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 two sentences, front-loaded with the core purpose and modes. No redundant information, every sentence adds value.

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?

With 9 parameters, no schema descriptions, and no annotations, the description is insufficient. It lacks parameter guidance and behavioral details, though output schema exists. The tool's complexity demands more comprehensive documentation.

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 coverage is 0%, so the description must compensate. It mentions config_name, git_url, source, and list_available implicitly, but does not explain destination, category, branch, token, or refresh. High-level modes are described but parameter mapping is incomplete.

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 tool fetches configs from API, git URL, or registered source, and supports three modes. It distinguishes from sibling tools like list_configs and validate_config by specifying the action of fetching or downloading.

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?

The description outlines three modes and when each might be used (named source, git URL, API). However, it does not explicitly state when not to use this tool or mention alternative sibling tools like list_configs for merely listing.

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