generate_plugin_skill

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

The description discloses that the tool writes SKILL.md to disk and explicitly notes it does not create scripts/ or assets/. It also states the return format as either a string or an error object, going beyond the idempotentHint annotation to clarify side effects and failure behavior.

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 contain the full purpose, side effect, and return behavior, with no filler. The main action is front-loaded in the first sentence.

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 schema and output schema, the description provides sufficient context: what it generates, where it writes, what it returns, and what it excludes. No critical information is missing for a user to use this tool correctly.

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 input schema covers all three parameters with descriptive text (100% coverage), and the description adds no additional parameter-level details. It references the plugin's fully-qualified name and type indirectly, but the schema already documents these sufficiently.

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 states a specific verb+resource: 'Generate a skill package for one plugin.' It clarifies scope (single plugin) and differentiates from sibling tools like generate_role_skill and generate_collection_skills.

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 phrase 'for one plugin' provides clear context for when to use this tool, implying the alternative generate_role_skill for roles. However, it does not explicitly name alternatives or exclusion criteria, so it stops short of a 5.

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