sync

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

The idempotentHint annotation indicates safe re-runs, but the description does not disclose what actions synchronization performs (e.g., installing/uninstalling packages, mutating the lockfile, requiring network). It leaves the user guessing about side effects and requirements.

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 short sentence, so it is concise, but it lacks substance. It does not earn its place by providing actionable information, unlike more useful descriptions that mention scope or alternatives. It is not overly verbose, but it is under-specified.

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?

Despite having full schema parameter descriptions, an output schema, and an idempotence annotation, the tool description is too vague to be complete. It fails to explain the tool's role in the project lifecycle or how it relates to many similarly named sibling tools, leaving the agent without adequate context to choose or invoke it correctly.

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?

All three parameters (locked, dry_run, upgrade) have full descriptions in the input schema, so the schema covers parameter semantics thoroughly. The tool description adds no parameter-level information, making a baseline score of 3 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 'Synchronize the project environment' identifies a verb (synchronize) and a resource (project environment), but it does not specify what synchronization entails or how it differs from sibling tools like pip_sync or lock. It is a clear but vague statement of purpose.

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?

No guidance is given about when to use this tool versus alternatives. The sibling list includes many tools that could overlap (e.g., pip_sync, lock, init), but the description offers no context for selection or exclusion.

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