create_project_snapshot

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

No annotations are provided, so the description carries full burden. It mentions analyzing changes via 'Serena' and saving incrementally/fully based on 'save count', but these are vague and undefined. It does not disclose side effects, permissions, or return behavior, leaving significant gaps for a mutation tool.

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 short and front-loaded with the core purpose. However, the second sentence introduces ambiguous terms ('Serena', 'save count') that reduce clarity. Still, it is concise without excessive wordiness.

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?

With 4 parameters, no output schema, and no annotations, the description is insufficient. It does not explain what happens after creation, what 'save count' means, who Serena is, or whether existing snapshots are affected. The complexity of a project snapshot tool demands more context.

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 does not add any parameter-specific meaning beyond what the schema already provides; it only references an unrelated 'save count' concept.

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 a project-wide snapshot creation with the verb 'Create' and resource 'project-wide snapshot'. The 'like Cursor' analogy helps, and 'project-wide' distinguishes it from sibling create_file_snapshot, giving it a specific scope.

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 explicit guidance on when to use this tool versus create_file_snapshot or other alternatives. The description implies project-level snapshots but does not mention exclusions or alternative tools. 'Like Cursor' is an analogy, not a usage directive.

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