Implementation Reference

  • The handler logic for list_statuses that interacts with the Redmine API to fetch issue statuses.
    def list_statuses(self) -> List[Dict[str, Any]]:
        try:
            return [
                {"id": s.id, "name": s.name}
                for s in self._redmine.issue_status.all()
            ]
        except Exception as e:
            raise RedmineError(f"list_statuses failed: {e}") from e
  • The tool registration and entry point for list_statuses in the MCP server.
    @mcp.tool()
    def list_statuses() -> List[Dict[str, Any]]:
        """Returns a list of available issue statuses."""
        logger.info("tool=list_statuses")
        try:
            return _client().list_statuses()
        except RedmineError as e:
            logger.error(f"list_statuses error: {e}")
            raise
Behavior2/5

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 but only states it 'returns a list' without detailing aspects like pagination, rate limits, authentication needs, or whether it's a read-only operation. This is inadequate for a tool with zero annotation coverage, as it leaves critical behavioral traits unspecified.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, efficient sentence with no wasted words. It's front-loaded with the core action ('Returns a list'), making it easy to parse quickly, and every part of the sentence contributes directly to understanding the tool's purpose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity (0 parameters, output schema exists), the description is minimally adequate but lacks depth. It doesn't explain what 'issue statuses' entail (e.g., open, closed, in progress) or how the output is structured, relying entirely on the output schema. For a list tool with no annotations, more context on behavior would improve completeness.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has 0 parameters, and the input schema has 100% description coverage (though empty). The description doesn't need to add parameter semantics, so it meets the baseline of 4 for zero-parameter tools, as there's nothing to compensate for.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

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 ('Returns') and resource ('list of available issue statuses'), making it easy to understand what it does. However, it doesn't explicitly differentiate from sibling tools like 'list_priorities' or 'list_trackers', which have similar naming patterns but return different resource types.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

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 prerequisites, context (e.g., for issue management workflows), or comparisons to siblings like 'list_issues' or 'search_issues_full', leaving the agent to infer usage based on naming alone.

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