decrypt_and_extract_dir

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

The description states the basic operation but lacks disclosures about batch behavior (e.g., overwrite policy, error handling, permission requirements). With no annotations, more detail is needed for full transparency.

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?

Extremely concise at one sentence, but lacks structure (e.g., bullet points). It earns its place but could be slightly more organized.

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 batch processing complexity and missing parameter documentation, the description is incomplete. While an output schema exists, the absence of param semantics and usage context leaves significant gaps.

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 coverage, the description should explain parameters, but it does not. base_path, output_dir, and appid are not described beyond the schema field names, providing no added meaning.

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's action (decrypt and extract) and target resource (every .wxapkg file in a package version directory), distinguishing it from siblings like decrypt_and_extract_appid which likely targets a single app.

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 guidance on when to use this tool versus alternatives (e.g., decrypt_and_extract_appid). No context on prerequisites or conditions, leaving the agent without decision support.

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