Managed Deep Agents - Skills
Summary
Skills allow managed deep agents to access specialized contexts and executable scripts dynamically, moving beyond static instructions. Skills are defined in a structured folder (`skills`) using `skill.md` files, which utilize 'progressive disclosure'—only basic information is given to the LLM initially. This system enables agents to perform complex tasks, such as asking follow-up questions or running Python scripts, and allows for centralized management of these skills via Context Hub without requiring code redeployment.
Key takeaways
-
Skills vs. Instructions
While instructions are always visible in the agent context, skills provide specialized, optional contexts that the agent can read or execute only when needed (progressive disclosure).
-
Skill Definition Structure
2:05
Each skill resides in a dedicated folder under `skills/` and requires a `skill.md` file. This file must contain front matter fields: `name` (the skill name) and `description` (what is shown to the LLM).
-
Executing Scripts
5:40
Skills can contain executable scripts (e.g., Python files like `hello.py`). The agent can identify, read, execute these scripts, and use their output as part of its response.
Technical details
-
Progressive Disclosure
85s
Only the skill's name and description are automatically provided to the LLM initially. Detailed information is loaded only when the LLM chooses to read or utilize the skill further.
-
Skill Implementation (Markdown)
135s
Skills are defined in `skill.md` files, requiring front matter fields for `name` and `description`. Example: Name='question asking', Description='Use this skill to ask follow-up questions when the user's initial question is vague.'
-
Agent Interaction Flow
250s
When an agent uses a skill, it first reads the relevant file (e.g., `skills/qa/skill.md`), which informs its behavior. If scripts are involved, the process includes listing files (`ls`) and executing commands (e.g., running Python).
-
Context Hub Management
430s
When deploying with MDA Dev, skills are pushed to Context Hub. This allows developers to modify skill content (e.g., changing text in `skill.md` or scripts) through the UI without redeploying the underlying code.
