gif_detect

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

Describes key analysis actions but does not explicitly state read-only nature, error conditions, or limitations. With no annotations, the description only partially discloses behavior; the agent must assume non-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?

Two sentences, front-loaded with purpose, then specific analyses. No redundant information; every sentence adds value. Ideal length for quick comprehension.

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 input and analysis actions but omits output details (format of report, boolean vs. detailed). Since no output schema exists, the description should describe the return value for completeness. Missing this context reduces completeness.

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?

Only one parameter (file_path) with schema description 'Path to GIF image file'. The tool description adds 'GIF file' context but no additional semantics beyond the schema. Schema coverage is 100%, so 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?

Clearly states auto-detection of steganography in GIF files, listing specific techniques (LSB, appended data, comment extensions) and reports (frame count, animation info). Distinguishes from sibling tools like gif_frame_analysis or gif_palette_lsb.

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?

No explicit guidance on when to use this tool versus alternatives. Does not mention when not to use it or suggest specialized tools for specific stego types, leaving the agent to infer from the description alone.

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