gif_lzw_analysis

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

With no annotations, the description carries the full burden. It describes the analysis behavior (checking sub-block sizes and entropy for anomalies) but does not explicitly state whether the tool is read-only, requires permissions, or has any side effects. The behavioral traits are adequately implied but not fully disclosed.

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?

Two concise sentences that front-load the action ('Analyze...') and add purpose ('Checks... for anomalies...'). Every sentence provides value; no fluff or redundancy.

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 one parameter, no output schema, and simple analysis purpose, the description is mostly complete. It explains what the tool does and why (steganography detection). Minor gap: could mention output format briefly, but not critical for this 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 coverage is 100% with a clear description for file_path. The tool description does not add additional meaning beyond what the schema already provides (path to GIF file). Per rules, baseline 3 is appropriate.

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 tool analyzes LZW compressed sub-block sizes and entropy in GIF images, with a specific focus on detecting steganographic manipulation. This verb+resource combination distinguishes it from sibling tools like gif_frame_analysis or gif_palette, which do not mention LZW analysis.

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 implies the tool is for detecting steganography in GIF LZW streams ('may indicate steganographic manipulation'), but it does not explicitly state when to use it versus alternatives or provide exclusion criteria. No guidance on prerequisites or when not to use it.

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