sync_skills

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

Annotations are absent, so the description must disclose behavioral traits. It only mentions the act of synchronization and the target locations, but does not clarify the direction of sync, potential side effects (e.g., overwriting files), or whether this is a read or write operation. This is insufficient for a mutation 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?

The description is a single, concise sentence with no fluff. It leads with the verb and primary resource, though the phrase 'with your personal skill collection... and global cache' is slightly ambiguous. Overall, it is efficient and front-loaded.

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 absence of output schema and annotations, the description is too thin. It fails to explain return values, side effects, or how this tool relates to sibling tools. For a sync operation with potential file mutations, this lacks critical context for an agent to use safely.

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 coverage is 100% with both parameters (configPath, projectPath) having meaningful descriptions. The tool description adds little beyond the schema, only reinforcing the config path. Baseline 3 is appropriate since the schema already documents the parameters adequately.

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 function with a specific verb 'Synchronize' and names the resources involved: project workspace skills, personal skill collection (~/.ai-skills/skills.config.json), and global cache. It distinguishes from sibling tools by implying a broader sync operation rather than install/remove/list, though it doesn't explicitly contrast them.

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 is provided on when to use this tool versus alternatives like install_skills or remove_skills. There is no mention of appropriate contexts, prerequisites, or exclusions, leaving the agent without direction on tool selection.

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