qwen_register_external_project

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

With no annotations, the description carries the full burden of disclosure. It does reveal a concrete side effect: writing a .txt link file with an absolute path. However, it says nothing about what the 'create' boolean does, whether the path must already exist, reversibility, or other behavioral consequences.

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?

One sentence contains the essential verb, target, and mechanism with no filler or repetition. The key detail of saving an absolute path is front-loaded and immediately usable.

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?

The tool has 3 parameters, no annotations, and no per-parameter descriptions. The 'create' flag is a significant behavioral fork that the description ignores, and there is no guidance on prerequisites, success criteria, or how this relates to materializing an external project. The output schema may cover return values, but it does not compensate for these 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?

The description adds meaningful parameter semantics by specifying that 'path' must be an absolute path and that registration is done via a link file. 'name' is inferable as the project identifier, but the optional 'create' parameter is entirely unexplained. With 0% schema description coverage, the description only partially compensates.

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 names a specific action (register), a target (external project), and the mechanism (saving its absolute path into a .txt link file). The 'external' qualifier helps distinguish this from qwen_create_project, though it does not explicitly name any sibling.

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 word 'external' implies this is for projects that exist outside the current project structure, but there is no explicit when-to-use or when-not-to-use guidance. It does not clearly contrast with qwen_create_project or qwen_resolve_project, leaving usage boundaries largely inferential.

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