package_skill

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

Annotations are absent, so the description must fully disclose behavioral traits. It mentions automatic uploading, but lacks details on whether the operation modifies the skill directory, requires specific permissions, or the outcome when no API key is set.

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 present the core action and additional behavior efficiently. No redundant information, though a more structured breakdown of parameters could improve clarity without adding excessive length.

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 description omits details about the output schema (present but not described), the behavior of the 'target' parameter when set to 'auto', and how this tool relates to the sibling upload_skill. This limits an agent's ability to fully understand when and how to use it.

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 compensates partially by linking skill_dir to the skill directory, hinting at target via platform listing, and auto_upload via upload behavior. However, it does not explicitly describe parameter values or defaults.

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 action: package a skill directory into platform-specific formats (ZIP or tar.gz) for specific platforms. It distinguishes from siblings like upload_skill or install_skill by focusing on the packaging aspect.

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 like upload_skill (which exists as a sibling). The description implies a use case but does not state exclusions or provide comparisons.

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