Create and refine OpenCode agents via guided Q&A. Use when creating an agent file, improving an existing agent, configuring AGENTS.md frontmatter, setting subagent_type, defining allowed-tools, restricting permissions, designing agent routing, writing a system prompt, configuring mode: subagent, setting a permission block, or working with the Task tool delegation pattern. Examples: 'Create an agent for code reviews', 'My agent ignores context', 'Add a database expert subagent', 'Make my agent…
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 Architect
Create and refine OpenCode agents through a guided Q&A process.
## Quick Start
Create `.opencode/agents/<name>.md`:
```markdown
---
description: Code review specialist. Use when user says "review", "check my code", "find bugs".
---
You are an expert code reviewer. Analyze code for bugs, security issues, and performance problems.
Provide specific, actionable feedback with line references.
```
For subagents (Task tool only), add `mode: subagent`. For permission restrictions, add a `permission:` block:
```yaml
---
mode: subagent
permission:
bash:
"*": "ask"
"npm test": "allow"
---
```
Run `bun run opencode` and type `/agents` to confirm the new agent appears in the list.
## Mindset
**An agent is a markdown file with YAML frontmatter.** Three decisions drive every design:
| Decision | Why it matters |
|----------|----------------|
| **Scope** (`description`) | Controls when the agent triggers — too vague = never fires, too broad = fires on everything |
| **Mode** (`mode:`) | `all` = visible everywhere; `subagent` = Task-tool only; `primary` = main list only |
…Read the whole file at its exact version.
How to install
mdr add pantheon-org/tekhne/opencode-design-agents@sha256:869f3cb8c22ad0a2The line at the top of this page pins the label git:20260316.2d4c8cf, 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.
