manage_project_file

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

No annotations are provided, so the description must fully disclose behavior. It mentions automatic file determination based on context but does not detail side effects (e.g., overwrite vs. append), permissions needed, or what happens if a file is missing. The description provides moderate transparency but lacks depth.

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 two sentences long, with no redundant words. The first sentence clearly states the function, and the second provides usage context, making it efficient and front-loaded.

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 has 3 parameters with 2 enums and no output schema. The description adequately covers the tool's purpose and usage, but lacks details on return behavior or error handling. For its complexity, it is mostly complete.

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 baseline is 3. The description adds value by explaining how the 'action' parameter maps to file types and how 'auto' mode works, going beyond the schema's enum descriptions.

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: automatically determining which project file to create or update based on context. It specifies the files involved (index.md, ROADMAP.md, etc.) and positions itself as the primary tool for project documentation changes, distinguishing it from sibling tools.

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 says 'Use this when making changes to the project' and explains the automatic determination logic. However, it does not explicitly state when to use sibling tools (e.g., create_or_update_todo) instead, leaving some ambiguity for precise actions.

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