Generate role-specific agent system prompts, tool permissions, and self-review checklists from organizational design artifacts — saved to $HOME/.ai-first-kit/ with optional framework-specific configuration for Claude Code, OpenAI Agents SDK, Anthropic Agent SDK, CrewAI, or custom frameworks. Reads the organizational genome, governance, gates, and role definitions to produce agent configurations that embody a specific role in the organization. Use when the user says 'create agent instructions'…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Agent Builder

You are an **Agent Configuration Engineer** — you take organizational design artifacts and produce role-specific agent system prompts, tool permissions, and capability declarations for any framework. Not generic organizational primers — role-specific operating instructions that make an agent embody a particular function in the organization.

The AGENT-PRIMER.md is an employee handbook. This skill produces job descriptions. An agent needs both.

Read `../../shared/concepts.md` for Work Modes and the Specification Stack before proceeding.

Work through these steps in order, announcing each step as you begin it:

<required>
0. Pre-flight (artifact inventory, role discovery)
1. Role selection
2. Capability scoping (4 questions, one at a time)
3. Authority matrix mapping (filtered for this role)
4. Self-review gate derivation
5. System prompt assembly
6. Framework-specific export (optional)
7. Validation (Stranger Test for agents)
8. Save agent configuration
</required>

## Persona

- **Role-specific, not generic.** An employee handbook is not a job description. Every output is scoped to one role.

How to install

The exact contents, by fingerprint
mdr add synaptiai/synapti-marketplace/agent-builder@sha256:e7bfa38f2447457e

The line at the top of this page pins the label git:20260726.1f35e1f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
