Radicle + GitHub MCP Server

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. The statement 'GitHub sync functionality is not available' implies this tool reports an error or status, but it doesn't specify the behavior (e.g., whether it throws an exception, returns a message, logs details, or provides diagnostic info). For a tool with zero annotation coverage, this leaves critical behavioral traits undefined.

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 extremely concise with a single, straightforward sentence: 'GitHub sync functionality is not available.' It is front-loaded and wastes no words, making it easy to parse. For a simple status-reporting tool, this brevity is appropriate and efficient.

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 the tool's complexity (simple status reporting) and the presence of an output schema (which likely handles return values), the description is incomplete. It fails to explain what the tool actually does behaviorally (e.g., returns an error code or message) or how it fits with siblings like 'rad_sync'. For a tool in a set of GitHub/Radicle operations, more context on its role is needed.

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 has 0 parameters, and schema description coverage is 100% (though trivial since there are no parameters). With no parameters to document, the description doesn't need to add semantic details beyond the schema. A baseline score of 4 is appropriate as the description doesn't contradict the empty schema and the absence of parameters is inherently clear.

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 'GitHub sync functionality is not available' is a tautology that essentially restates the tool name 'github_sync_unavailable'. It doesn't specify what action this tool performs (e.g., returns an error message, logs unavailability, provides fallback options) or what resource it operates on. While it hints at a status reporting function, it lacks a clear verb+resource statement that distinguishes it from its sibling 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. It doesn't mention any context for invocation (e.g., when GitHub sync is attempted but unavailable), prerequisites, or relationships to sibling tools like 'rad_sync'. Without explicit or implied usage instructions, agents must infer context from the name alone, which is insufficient.

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