fetch_config

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states this is a retrieval operation (implying read-only) and mentions possible failure ('or None if failed'), which adds useful context. However, it doesn't describe authentication needs, rate limits, what specific configuration data is returned, or how failures manifest beyond returning None.

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 appropriately sized and front-loaded with the core purpose in the first sentence. The parameter and return sections are structured but slightly verbose for a zero-parameter tool. The mention of 'ctx' parameter that doesn't align with the schema creates minor inefficiency.

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 this is a read operation with no annotations, no output schema, and zero parameters, the description is minimally adequate. It covers the basic purpose and return behavior but lacks details about what configuration data is included, format specifics beyond 'stringified JSON', or error handling beyond returning None. For a configuration retrieval tool, users would benefit from more context about the data structure.

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 input schema has 0 parameters with 100% coverage, so the schema fully documents the absence of parameters. The description adds value by explicitly stating there's a 'ctx' parameter (though this appears to be documentation convention rather than an actual parameter based on the schema) and clarifying the return type semantics. Since there are no actual parameters to document, this exceeds the baseline.

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's purpose with a specific verb ('Retrieve') and resource ('current bot configuration'). It distinguishes itself from siblings like 'reload_config' (which likely modifies configuration) and 'fetch_bot_status' (which retrieves operational status rather than configuration). However, it doesn't explicitly differentiate from all possible configuration-related tools.

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 provides no guidance on when to use this tool versus alternatives. While it's implied this is for reading configuration (vs. 'reload_config' for updating), there's no explicit mention of prerequisites, timing considerations, or comparisons to other fetch tools like 'fetch_bot_status' that might provide overlapping information.

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