audio_lsb_extract

Extract hidden data from WAV audio files by reading the least significant bit of PCM samples. Decodes concealed messages or files stored in audio LSB steganography.

Instructions

Extract LSB data from audio samples. Reads the least significant bit of each PCM sample and attempts to decode hidden data.

Behavior2/5

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

With no annotations provided, the description carries full burden for behavioral disclosure. It mentions extraction and decoding attempts but lacks details on file modification, return behavior on failure, or prerequisites. Essential safety information is missing.

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 two sentences long, no wasted words, and directly addresses the tool's function. It is efficiently front-loaded with the key action.

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

Completeness3/5

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

Given the lack of output schema and annotations, the description is minimal but covers the basic action. However, it omits details on return format, error handling, and behavior for empty or missing hidden data, making it only adequately complete for a simple tool.

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?

Schema coverage is 100%, so the description adds no additional meaning beyond the schema. It does not explain parameter formats or provide context beyond what is already in the schema. Baseline score 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 the verb 'extract' and the resource 'LSB data from audio samples', and distinguishes itself from the sibling tool 'audio_lsb_detect' by focusing on extraction rather than detection.

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

Usage Guidelines3/5

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

The description implies usage for extracting hidden data from audio files but does not explicitly state when to use this tool versus alternatives like 'audio_lsb_detect' or other steganography tools. No when-not-to-use or alternative names are mentioned.

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