Returns the current toolkit state: installed MCPs, their connection status, the accounts connected to each one, and how many catalog tools each exposes.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and destructiveHint. The description is consistent with these, adding detail on return content but no further behavioral context like rate limits or data freshness. It meets the minimum bar but doesn't enrich beyond annotations.
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 a single, well-structured sentence that front-loads the action and then lists the returned components. Every clause adds value, with no filler or repetition.
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?
For a simple read-only info tool with no parameters and no output schema, the description fully specifies the tool's scope and output. An agent can confidently decide when and how to invoke this tool based on the provided detail.
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 zero parameters, and schema coverage is trivially 100%. The description adds clarity about what the returned state includes, which is useful given no parameter details are needed. Baseline for 0 params is 4 and the description meets it.
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 function with a specific verb ('Returns') and identifies the resource ('current toolkit state'). It enumerates the specific content returned (installed MCPs, connection status, connected accounts, catalog tool counts), which distinguishes it from sibling tools like authenticate or list_accounts.
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 implies clear usage context: call this to inspect toolkit state. It doesn't explicitly mention when not to use it or name alternative tools, but the context is obvious from the description and sibling list. A strong but not fully explicit guideline.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Add one secure layer between your agents and this server.
Every tool has a clearly distinct purpose. The Garmin-specific tools each handle a unique operation on workouts or accounts, and the platform tools (authenticate, connect, marketplace, etc.) are separate and easily distinguishable.
The naming is inconsistent: Garmin tools use a consistent 'garmin_verb_noun' pattern, but the platform tools (authenticate, connect, marketplace, report_bug, show_version, toolkit_info) lack any prefix or pattern, creating a mismatch.
With 16 tools, the count is slightly above the typical sweet spot but still justified. The domain of workout management requires several operations, and the platform utilities are essential for the server's operation within the MCP ecosystem.
The Garmin workout tools cover the full lifecycle: create, retrieve, update, delete, plus scheduling. Listing accounts and the platform utilities round out the surface. Minor gaps (e.g., no tool to fetch activities) are acceptable given the server's focus on 'treinos' (workouts).
