extract_exif_tool

Extract EXIF and metadata from files, including images, documents, and media. Retrieve camera info, GPS coordinates, timestamps, and hundreds of other fields.

Instructions

Extract EXIF and metadata from a file using ExifTool.

Supports images, documents, media files, and many other formats. Extracts: camera info, GPS coordinates, timestamps, software versions, author information, and hundreds of other metadata fields.

TDQS

A4/5.0
Behavior3/5

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

No annotations are provided, so the description carries the full burden. It implies a read-only operation by using 'Extract' and mentions the underlying ExifTool, but it does not disclose potential side effects, limitations, or error behavior. This is adequate but not rich.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise and front-loaded with a clear verb and resource. Two sentences plus a bulleted list of examples convey the necessary information without any wasted words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool is simple (one parameter) and has an output schema, so the description does not need to explain return values. It adequately covers supported formats and the breadth of metadata extracted, though it could mention error conditions or file size limitations.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 100% coverage with a simple 'file_path' parameter described as 'Path to the file'. The description adds no further meaning to the parameter beyond what the schema already provides, so the baseline of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states a specific action (extract EXIF and metadata) on a specific resource (a file) using a well-known tool (ExifTool). It clearly differentiates from sibling tools like extract_strings_tool or calculate_hashes_tool, which serve different purposes.

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

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides clear context on what types of files are supported and what kind of metadata is extracted, implying when to use it. However, it does not explicitly mention alternatives or when not to use it, though the extensive list of supported formats makes the intended use fairly obvious.

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