Skill system

What a Skill is

A Skill bundles prompts, tools, and workflows into a standardized unit so Agents can invoke domain expertise like calling a function.

One Skill ≈ best practices for one professional role

Examples:

• document-editing — in-place binary Docx/Xlsx/Pptx editing
• code-review — code review (built-in MISRA / ISO 26262 rules)
• patent-agent — patent drafting (claims / specification / figures)
• lark-im — Feishu IM operations
• graft — cross-session output references

├── SKILL.md              ← required: metadata + prompt snippets
├── tools/                ← optional: skill-specific tools
├── references/           ← optional: referenced docs
└── tests/                ← optional: contract tests

SKILL.md front matter defines:

• name — skill id; /slash command activation
• description — trigger phrases and scenarios
• execution_mode — precise / balanced / creative
• tags — categories

Activation

Skills are activated on demand so they do not bloat the default Agent context:

Source tiers

• builtin — official platform Skills
• tenant — enterprise Skills (tenant-wide)
• user — personal Skills

SkillHub

Organizations and the community publish, subscribe, and update Skills to grow the ecosystem.
