Provides context for debugging REPLs, suggesting use to verify sessions before sending input. Does not explicitly exclude alternative tools but gives practical usage guidance.

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?

Annotations already declare destructiveHint=true, signaling potential deletion or modification. The description adds context about path normalization and allowed directories but does not disclose behavior if destination already exists (e.g., overwrite or error). This is a notable gap for a destructive operation.

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 concise with two short paragraphs. The first sentence immediately states the core purpose. The second paragraph contains essential usage notes. No unnecessary information, and structure is front-loaded effectively.

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 two-parameter schema and lack of output schema, the description covers purpose, constraints, and path guidance. It lacks details about return values, error conditions, or behavior on conflict, but overall it provides sufficient context for basic usage.

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 0% description coverage for both parameters. The description clarifies that source and destination are paths and recommends absolute paths, adding some guidance. However, it does not explicitly describe each parameter's expected format (e.g., source must be an existing file/directory) or constraints beyond paths.

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 explicitly states the tool moves or renames files and directories, using specific verbs and resources. It clearly distinguishes from sibling tools like write_file or create_directory by focusing on relocation/renaming rather than creation or content modification.

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 provides explicit guidance on using absolute paths, warnings about relative and tilde paths, and mentions that source and destination must be within allowed directories. However, it lacks explicit 'when not to use' or comparison to alternatives like copy instead of move.

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?

Annotations already declare readOnlyHint and openWorldHint. The description adds significant behavioral details: offset/length semantics, performance optimizations, format-specific output, and path restrictions. No contradiction with annotations.

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 verbose and could be more concise. It includes extensive details on format handling and workflows, which are valuable but not all essential for basic use. The structure is clear but front-loads information well.

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 tool's complexity (8 params, multiple formats, no output schema), the description covers most needed context: file types, offset/length, URL support, performance, and restrictions. It lacks some details like return value format for all cases, but overall comprehensive.

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?

With 0% schema description coverage, the description compensates fully. It explains all key parameters (offset, length, range, sheet, isUrl) with examples and edge cases, making their meaning and behavior clear beyond the 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?

The description clearly states 'Read contents from files and URLs' with specific format handling for PDF, Excel, images, DOCX, etc. It distinguishes itself from sibling tools like 'execute_command' by recommending its use for viewing 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 provides clear guidance: prefer over 'execute_command', use offset/length for partial reading, always use absolute paths, and includes an editing workflow for DOCX. It implicitly advises when not to use it (e.g., for URLs, full content read).

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?

Annotations indicate readOnlyHint=true (non-destructive). Description adds behavioral details: partial failure (failed reads don't stop operation), image handling as viewable content, and path normalization. No contradictions with annotations.

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?

Description is moderately sized with clear structure. First sentence captures purpose. Some repetition in path guidance could be condensed, but overall efficient.

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 essential aspects: file reading behavior, image support, failure handling, directory constraints, and path recommendations. Sufficient for a file-reading tool.

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 0% description coverage, so description carries full burden. It explains that content is returned with path references and that images are handled. Adds path advice (absolute paths). Could be more specific about array constraints (e.g., max size) but adds significant value 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?

Description clearly states 'Read the contents of multiple files simultaneously' with specifics on content handling (text and images) and lists recognized image types. Distinguishes from sibling 'read_file' by focusing on multiple files.

Annotations provide readOnlyHint=true, and the description elaborates with offset behavior, output protection, smart features, and detection states. No contradiction; adds significant value beyond annotations.

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 examples, but somewhat verbose. Redundant phrases like 'This command can be referenced...' could be removed. Front-loaded purpose, but length could be trimmed without losing clarity.

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?

Covers tool purpose, all parameters except verbose_timing fully, output protection, and detection states. No output schema, but describes return format partially with examples. Mostly complete for the tool's complexity.

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 0%, so description must compensate. It thoroughly explains offset and length with examples, mentions timeout_ms, but does not explicitly describe pid or verbose_timing. Partial coverage, so score 3.

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 'Read output from a running process with file-like pagination support.' The verb 'read' and resource 'output from a running process' are specific and unambiguous. Distinguishes from siblings like read_file and interact_with_process.

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?

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?

Annotations already set destructiveHint=true, but the description adds critical behavioral context: warns about security risks and specifically explains that setting allowedDirectories to empty array grants full file system access. This goes beyond annotations.

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?

No contradiction.

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 quite long and includes repetitive elements (e.g., workflow and common patterns both mention python3 -i). However, it is well-structured with clear sections and front-loaded with critical purpose and rules. Some pruning would improve conciseness.

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?
