Calculator Skill 提供数学计算能力，支持加减乘除、幂运算等基本数学运算。
当用户需要计算数学表达式时使用此技能，例如：
调用 calculator 工具，输入数学表达式。
expression: 数学表达式（字符串）
+, -, *, /, ^(, )3.14输入: 2 + 3 * 4
输出: 14
输入: (10 + 5) / 3
输出: 5
输入: 2 ^ 10
输出: 1024
用户: 计算 25% 的 200 是多少？
助手: 让我用计算器来算：
所以 25% 的 200 是 50。
用户: 帮我算一下 2 的 10 次方
助手: 使用幂运算计算：
结果是 1024。
Deep bug analysis to break the fix-forget-repeat cycle. Analyzes root cause category, why fixes failed, prevention mechanisms, and captures knowledge into specs. Use after fixing a bug to prevent the same class of bugs.
Understand and customize the local Trellis architecture inside a user project. Use when modifying .trellis plus platform hooks, settings, agents, skills, commands, prompts, workflows, the channel runtime (trellis channel), bundled runtime agents under .trellis/agents/, selectable workflow templates, registry-backed spec refresh, cross-session memory (trellis mem) generated by trellis init, or AI-facing bundled skills (trellis-channel, trellis-session-insight, trellis-spec-bootstrap) and bundled-skill auto-dispatch flow.
Captures executable contracts and coding conventions into .trellis/spec/ documents. Use when learning something valuable from debugging, implementing, or discussion that should be preserved for future sessions.
