fetch_config

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

With no annotations, the description must disclose behavioral traits. It does not explain what happens on errors, whether files are overwritten, or the effect of parameters like 'refresh' and 'destination'. Only inputs are described, not side effects or return behavior.

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 long with no fluff. It front-loads the main purpose and then succinctly lists modes. Could be slightly more structured but is effective.

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?

Given 9 parameters, no annotations, and an output schema present but not described, the description lacks completeness. It does not cover behavior of all modes, error handling, or return format. Sibling differentiation is minimal.

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 0%. The description mentions 5 of 9 parameters (config_name, git_url, source, list_available, category) but omits 'destination', 'branch', 'token', 'refresh'. It adds limited meaning beyond the schema for the mentioned parameters.

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. It explicitly lists three modes and mentions both listing and downloading, distinguishing it from siblings like list_configs (likely only lists) and others.

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 but provides no explicit guidance on when to use each mode or when to prefer this tool over siblings like list_configs or generate_config. Usage context is implied but not explicit.

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