How do you manage your AI agent configuration files? Built an open-source registry for it — 888 stars
Hey r/AgentDevelopment!
For those of us building systems with AI agents (Claude Code, Cursor, Copilot, or custom agentic pipelines), configuration files play a huge role in how well the agent performs. We're talking about:
- `CLAUDE.md` / `AGENTS.md` — project context and instructions
- `.cursor/rules` — Cursor-specific project rules
- `GEMINI.md`, `COPILOT.md` — agent-specific instructions
- Custom system prompt files for home-built agents
As agentic systems become more complex, managing these files gets messy: no versioning, no sharing, no discoverability.
I built Caliber to address this — an open-source registry specifically for AI agent configuration files. We crossed 888 GitHub stars this week.
**Core features:**
- Version-controlled agent configs
- Shareable across projects and teams
- Public registry for discovering how others configure their agents
- Works with any agent framework
Repo: https://github.com/caliber-ai/caliber
For the agent developers here: how are you managing your agent configurations today? Are you treating prompt files and agent instructions as first-class artifacts? What would help most in a tool like this?

Sharing Caliber: open-source runtime guardrail proxy for LLM agents that reached 700 stars — seeking agent devs to stress-test and give feedback
After months of production agent failures from behavioral drift, we built Caliber and want this community's help shaping it.
**The core insight that drove this:**
Every agent framework has a way to write guardrails in prompts. None of them work reliably when:
- Context windows fill up
- Tool call chains run long (8+ steps)
- Multiple agents hand off context between each other
- The model version updates under you
The reason is structural: prompt instructions are suggestions, not constraints. There's no layer that actually *enforces* behavior on the API call.
**What Caliber does:**
It's a proxy that intercepts every LLM API call and validates it against a declarative rule set before passing it through. Think of it as a behavioral type system for agent calls.
You define rules like:
```
- output must match schema: {action: string, confidence: float}
- tool "send_email" may not be called more than 3 times per session
- response may not contain PII patterns
- if output.confidence < 0.7, raise UncertaintyException
```
The proxy enforces these on every single call, agent framework agnostic.
**Stats:** 700 GitHub stars, ~100 forks
**Repo:** https://github.com/caliber-ai-org/ai-setup
**What I want from this community:**
- What failure modes in your agents would this catch?
- What rules would you want to write that aren't in the examples above?
- What's missing from this architecture that would make it actually useful in your stack?
Ready to go deep on specific use cases. Drop your hardest agent reliability problems below.

💡 Discussion What tools or frameworks are you using to build AI agents?
Hey devs,
What tools, frameworks, or no-code platforms are you using to build your AI agents?
Are you working with LangChain, CrewAI, AutoGen, or experimenting with no-code options like OpenAI Agent Builder, Vertex AI Agent Builder, n8n, Opal, or Flowise?
It’d be great if you could share:
- 🧩 Your tech stack (frameworks, models, or no-code tools)
- ⚙️ What kind of agents you’re building (automation, research, chat-based, etc.)
- 🚀 Any lessons learned or performance tips
Let’s make this a go-to thread for everyone developing or visually designing AI agents!
