authenticate

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

No annotations are provided, so the description must disclose behavior fully. It mentions OAuth, implying user redirection and token handling, but does not explain side effects (e.g., whether tokens are stored, if the tool is reusable, or error states). For a one-time setup, this is insufficient detail.

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 (one line) and front-loaded with the key action. Every word is meaningful; the phrase 'À lancer une seule fois' adds valuable usage context without redundancy.

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 low complexity (one-time OAuth auth), the description is largely complete. It covers the core action and usage frequency. However, it lacks details on failure modes or re-authentication, and the output schema is not described, but that is not required per instructions if output schema exists.

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?

There are zero parameters, so the input schema is fully covered. According to guidelines, baseline for 0 parameters is 4. The description does not need to add parameter details, and it correctly focuses on the action.

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 verb 'Connecte' (connect) and the resource 'ton compte Strava' (your Strava account) via OAuth. It explicitly distinguishes itself from sibling tools (data retrieval/analysis) by being an authentication step, and 'À lancer une seule fois' reinforces its one-time nature.

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 usage guidance by stating 'À lancer une seule fois' (run only once), implying it is a setup step. However, it does not explicitly state when to use vs alternatives or mention prerequisites (e.g., having a Strava account). No sibling authentication tools exist, so differentiation is unclear.

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