write_file

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

With no annotations provided, the description carries the full burden. It discloses the important behavior of automatically creating parent directories, but it does not mention whether writes overwrite existing files or any path traversal restrictions. This is a partial disclosure.

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, concise sentence that includes the core action, the target workspace, and a key behavioral detail. It is front-loaded and free of unnecessary words.

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?

For a tool with only two required parameters, no output schema, and low complexity, the description is fairly complete. It states the primary function and an important side effect. It could mention overwriting behavior, but for a write tool this is often assumed, so the description is sufficient for most use cases.

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% because both path and content have descriptions in the input schema. The description adds no new parameter-level details beyond the schema's own descriptions, so it stays at the baseline for high coverage.

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 uses a specific verb 'write' plus resource 'file to workspace' and adds a distinct behavioral detail (auto-creating parent directories). This clearly identifies the tool's function and distinguishes it from siblings like read_file and list_files.

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 does not explicitly state when to use this tool or mention alternatives, but it implies usage for writing files in the workspace. The context of sibling tool names provides some implicit guidance, but there is no explicit when-to-use or when-not-to-use.

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