sysknife_execute

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

Without annotations, description partially covers behavioral traits by disclosing the critical approval requirement. However, it does not mention execution order, synchronicity, or error behavior, leaving gaps for the agent.

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 with no redundant information. First sentence states core purpose, second sentence adds essential usage constraint. Every word earns its place.

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 output schema exists and the single parameter is well-documented, the description provides sufficient context including prerequisite (sysknife_plan) and approval flow. Could mention error handling or return format but overall adequate.

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 has 100% coverage with descriptions for all parameters. The description adds value by clarifying that steps should be taken verbatim from sysknife_plan output and that approval_receipt is a one-time receipt, enhancing parameter understanding.

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 the tool executes steps produced by sysknife_plan, specifying the verb 'execute' and the resource 'exact steps'. It differentiates itself from the planner tool sysknife_plan by indicating the output source.

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?

Description explicitly requires a one-time receipt from CLI approval and states MCP cannot approve its own mutations, providing when-not-to-use context. However, it does not name alternative sibling tools for other use cases.

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