skillNinja_uninstall

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

With no annotations provided, the description carries full burden for behavioral disclosure. It mentions the tool 'Removes skill folder and updates AGENTS.md', which implies destructive changes, but doesn't specify permissions needed, whether the action is reversible, or any side effects like dependency impacts. This is a significant gap 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 brief and front-loaded with the main action, but includes redundant Japanese translation ('/ スキルをアンインストール') that adds no value for an AI agent. Otherwise, it's efficiently structured in a single 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 this is a destructive mutation tool with no annotations and no output schema, the description is incomplete. It should address behavioral aspects like error conditions, confirmation prompts, or what happens to dependent skills, but provides only basic action details.

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 100%, so the schema already documents both parameters ('skillName' and 'workspacePath'). The description adds no additional meaning or context about these parameters beyond what the schema provides, meeting the baseline for high coverage.

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 ('Uninstall') and resource ('Agent Skill from the workspace'), and mentions specific effects ('Removes skill folder and updates AGENTS.md'). However, it doesn't explicitly differentiate from siblings like 'skillNinja_remove' or 'skillNinja_delete' (though none exist), so it's not a perfect 5.

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 description provides no guidance on when to use this tool versus alternatives like 'skillNinja_install' or 'skillNinja_updateIndex'. It lacks context about prerequisites (e.g., skill must be installed first) or exclusions, leaving the agent with minimal usage direction.

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