write_multiple_files

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

With no annotations, the description covers concurrency, format support, auto-detection, partial failure handling, and restricted directories. Missing explicit statement about overwrite behavior and return value details, but overall good.

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?

Well-structured with sections and bolded IMPORTANT note. Slightly verbose (e.g., redundant auto-detection statement), but overall efficient and front-loads key info.

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?

Given no output schema, description covers format support, error handling, allowed directories, and multi-line content. Lacks explicit overwrite behavior and return fields, but sufficiently complete for agent use.

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 has 100% coverage with description on content field. Description adds nuance about multi-line content using actual newlines and auto-detection, but does not significantly expand beyond schema.

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?

Clearly states it writes multiple files concurrently, supports text, PDF, DOCX with HTML formatting, and auto-detects file type by extension. Distinguishes from sibling `write_file` which handles single files, and other file operations.

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?

Provides context for when to use this tool (multiple concurrent writes) and includes important constraints like allowed directories. Lacks explicit when-not or alternatives like `write_file`, but the intent is clear.

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