社区实战：遇到“OpenClaw 做不到”时，用自定义 Skill 补齐能力
问题/场景：默认工具链无法覆盖特定动作，导致用户流程中断。前置条件：具备本地开发环境并可修改 skills 目录。实施步骤：1) 定义失败场景与输入输出契约；2) 用最小功能写一个 skill；3) 在沙箱中回归测试；4) 增加错误处理与边界提示；5) 发布并写使用文档。关键命令：`npm run build`、`git status`、`openclaw help`。验证方法：原失败场景可稳定复现并被 skill 成功处理。风险与边界：技能权限过大可能引入安全风险，需最小权限设计。来源归因：Reddit 讨论 + skill 文档实践。

Prerequisites
- You can edit and test skill files in the workspace.
- A reproducible failing scenario is captured before coding the new skill.
Steps
- Write down the exact user task that currently fails and define expected output schema.
- Implement a minimal skill that only solves the target gap (no extra permissions).
- Run local/sandbox tests with both happy-path and malformed inputs.
- Add explicit error messages and fallback handling for unsupported cases.
- Document usage examples and maintenance boundaries in SKILL.md.
Commands
npm run buildgit statusopenclaw helpVerify
The original failing workflow now succeeds in at least 3 repeated runs without widening tool permissions.
Caveats
- Do not grant shell/network permissions unless the scenario explicitly requires them.
- Version drift between skill spec and runtime may break execution（需验证）.
