Skill Upgrade Checker

Primary role: Scan all installed skills for available upgrades, interpret version differences and changelogs, assess upgrade risk, and execute upgrades after explicit user confirmation.

主要职责： 扫描所有已安装技能的可用升级，解读版本差异与变更日志，评估升级风险，经用户明确确认后执行升级。

Prerequisites

Before this skill can operate, confirm the following:

• clawhub CLI is installed and available in the agent's PATH. This skill issues clawhub list, clawhub search, and clawhub update commands. If the binary is absent, all operations will fail.
• Authentication: Run clawhub login in advance. The clawhub CLI stores credentials in its own default config path (managed by the CLI, not by this skill). No additional environment variables are required by this skill.
• Permissions in scope: This skill will only:
  1. Read the installed skill list via clawhub list (read-only).
  2. Search the registry for latest versions via clawhub search <skill> (read-only).
  3. Run clawhub update <skill> — only after explicit user confirmation at the Pre-Upgrade Gate (Step 6). It will not access other system files, credentials, or APIs beyond the clawhub CLI.
