No annotations provided, so description carries full burden. It discloses that images are presented to the AI as if uploaded by the user, requires client vision support, and is restricted to allowed directories. No contradictory or omitted behaviors.

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?

Four concise sentences, each providing essential information: purpose, behavior, format support, and constraints. No redundant or extraneous content. Information is 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?

Given the simple tool (one parameter, no output schema), the description covers purpose, usage, format, and requirements adequately. Could mention if images are stored temporarily, but not critical.

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 coverage is 100%, but description adds value: explains the 'path' parameter accepts single or multiple images, and advises providing an array for compatibility. This goes beyond the schema's basic description.

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 verb and resource: 'Attach an image file for AI vision analysis.' It explains the purpose (enable AI to see and describe visual content) and distinguishes from file operation siblings like delete_files, read_file, etc.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

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?

Comprehensive for a write tool: covers formats, encoding, directory limitations, and multi-line handling. No output schema, but return behavior is implied. Appropriate given sibling tools and no nested objects.

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?

Adds significant meaning beyond the input schema: path context (allowed directories) and extensive content details (format support, HTML tags, multi-line instructions). Schema coverage is 50%, but the description compensates fully.

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 'Create/replace files' and specifies supported formats (text, PDF, DOCX with HTML). Distinguishes from sibling tools like edit_file (for modifying) and read_file (for reading) by focusing on writing and specific formats.

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 explicit guidance on multi-line content formatting and allowed directories. Implies appropriate use for creating/replacing files, but does not explicitly state when not to use or mention alternatives like edit_file for editing.

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

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.
