nexo_skill_create

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

No annotations provided, so description must disclose behavioral traits. It mentions creating a skill but does not specify whether it overwrites existing skills with same id, what happens on id conflict, required permissions, or return behavior. This is insufficient for a creation tool.

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 of 14 words, very concise. Lists key components upfront. However, no structural elements like bullet points or separations, and could benefit from additional clarity without adding much 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?

Given 16 parameters with many defaults and no output schema, the description is incomplete. It does not explain what the tool returns, how to interpret success, or how defaults interact. Also fails to provide context among many sibling tools.

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?

Schema description coverage is 0%, so description must add meaning to parameters. It mentions 'guide/execute/hybrid metadata, triggers, params schema, and execution level' which maps to a few parameters (level, trigger_patterns, params_schema, execution_level), but ignores 12 other parameters like id, name, description, tags, etc. Without parameter descriptions in schema, this is inadequate.

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?

Description clearly states 'Create a new skill' and lists key components (guide/execute/hybrid metadata, triggers, params schema, execution level). However, it does not differentiate from other skill creation tools like nexo_skill_compose or nexo_skill_merge, which could create similar 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?

No guidance on when to use this tool vs alternatives. With many skill-related siblings (apply, approve, compose, merge, etc.), the description should explicitly state when to use create instead, but it does not.

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