Decide Fit First

• Core job: 当你在改进智能体的规划、调用工具、从错误中恢复以及收敛到完成状态的方式时，使用此技能。 1. 行动空间质量 2. 观察质量 3. 恢复质量 4. 上下文预算质量 1. 使用稳定、明确的工具名称。 2. 保持输入模式优先且范围狭窄。 3. 返回确定性的输出形…
• Best fit: Use it when the task has reusable inputs, steps, and validation criteria rather than a one-off answer.
• Avoid forcing it: If the source lacks commands, platform support, or external-service evidence, keep those fields unknown instead of guessing.

Design Intent

• Structure: The skill is organized around “核心模型”, “行动空间设计”, “粒度规则”, “观察设计”, showing how the author expects the agent to judge fit, collect context, and produce verifiable output.
• Trigger evidence: Prioritize the author’s wording around when to use it, what context to collect, and what output shape to produce.
• Evidence boundary: Author text states facts, repository files prove commands and paths, and Fluxly only adds fit, limits, and usage judgment.

How To Use It

• Inputs: Provide target material, scope, expected result, forbidden changes, and validation method.
• Invocation: Name agent-harness-construction directly; if the source includes slash commands, start with the command and then add task context.
• Validation: Start small and check whether the result follows “核心模型 / 行动空间设计 / 粒度规则” before expanding.

Boundaries And Review

• Dependencies: It usually needs no extra API key, so start with a small validation task.
• Permissions: Declared permissions include read; ask the agent to state file, command, and rollback boundaries before acting.
• Quality bar: A useful result names the deliverable, evidence, and next action. Generic prose means the task needs tighter context.
