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

With no annotations, the description carries the full burden. It discloses idempotency and preservation of existing VIBE.md and vibe.config.json files, which are useful behavioral notes. However, it does not mention side effects, error conditions, authentication requirements, or what happens when files are absent. The disclosure is partial but not contradictory.

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 sentence that front-loads the core purpose and adds two key behavioral guarantees (idempotency and file preservation). There is zero waste; every clause earns its place. Structure is optimal for a tool with such a narrow scope.

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?

The tool lacks an output schema, so the description should explain what the tool returns or how the agent should interpret the result. It does not. It also omits details about failure modes, the impact of the optional url parameter, and any prerequisites like existing project structure. For a tool that performs detection and configuration, this is incomplete.

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?

Schema description coverage is 100%, so the baseline is 3. The description adds no extra meaning to the parameters beyond what the schema already states. It neither clarifies the url parameter's role nor the codebase_path format. The schema is adequate, so a 3 is appropriate.

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: configuring a project and detecting its framework, running server, and authentication method. It names the resource (project) and the actions (configure, detect). While it does not explicitly distinguish from siblings, the sibling list contains no overlapping tools, so clarity is high.

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 or when not to use it. There is no mention of exclusions, prerequisites, or conditions that would lead an agent to choose this tool over another. The purpose is implied but not explicitly framed against other options.

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