install_skill

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

With no annotations, the description transparently discloses that the tool is 'reserved for future' – indicating it likely performs no action currently. It also clarifies that workspace skills are managed elsewhere, avoiding unintended use.

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 two sentence long, efficient, and immediately conveys the purpose and context. No redundant words.

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 tool is a placeholder, the description adequately covers its reserved nature, current non-functionality, and alternative methods. No output schema needed.

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% (all 3 parameters documented). The description adds minimal value beyond the schema, only hinting that skill_name refers to external skills. Baseline 3 is appropriate given 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 tool is 'Reserved for future external skill installation' and distinguishes it from managing workspace skills via team-memory or Agent Portal UI. This provides a specific verb+resource and differentiates from sibling tools.

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 implies not to use this tool for workspace skills by pointing to alternatives, but lacks explicit when-to-use guidance for the future external installation scenario. However, it clearly advises against current misuse.

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