Kelet is a root-cause analysis agent for LLM applications that goes beyond trace visualization. Where most observability tools stop at showing you what happened, Kelet automatically reads your traces, cross-references failure patterns across thousands of sessions — thumbs-down ratings, abandoned conversations, LLM-judge flags — generates root cause hypotheses, and produces targeted prompt patches to address them. The workflow is: connect your traces (LangSmith, Langfuse, or direct API), let Kelet ingest your failure signals, and receive a prioritized list of failure clusters with explanations and draft prompt fixes. SOC 2 Type II certified, read-only access to traces — nothing is mutated. The indie team positions it as the missing "closing of the loop" in LLM observability: most teams can detect failures but have no systematic path from detection to fix. The HN thread surfaced a real pain point: teams know their chatbot is failing somewhere, but diagnosing which prompts, tools, or routing decisions are responsible requires manual trace archaeology. Kelet automates that archaeology and produces actionable output, not just dashboards.

Oh My Codex (OMX) is an orchestration layer for OpenAI's Codex CLI, inspired by oh-my-zsh. It transforms the bare Codex CLI into a full multi-agent coordination platform: parallel agent teams running in isolated git worktrees, persistent memory and state across sessions, 33 specialized prompts for common dev tasks, a hooks system for automation, and terminal HUD displays. The project exploded to 12,600+ GitHub stars with nearly 3,000 gained in a single day — one of the fastest-trending repos on GitHub Trending. It fills a real gap: Codex CLI is powerful but raw, and OMX adds the orchestration primitives that serious agentic dev workflows need without requiring a completely different tool. Parallel worktrees are the standout feature — each agent gets a clean isolated branch, and OMX handles merging and conflict resolution. The hooks system lets you trigger OMX agents from git events, CI, or external scripts. It's MIT licensed and pure community energy — no VC, no startup, just a builder scratching their own itch.
Reviewer scorecard
“The loop has been open for too long — collect traces, stare at them, guess at fixes, repeat. Kelet closes it. Read-only access is the right trust model for early adoption. If it actually surfaces actionable prompt patches instead of generic insights, this becomes a staple of any serious LLM app development workflow.”
“Parallel worktree agents with automatic merge coordination is exactly the missing piece in Codex CLI. I ran three specialized agents simultaneously on a refactor last night and the hooks system handled the integration. 12K stars in a day doesn't lie — ship it.”
“Automated prompt patches from an LLM analyzing other LLM failures is a confidence game — how do you know the fix didn't introduce a new failure mode? Without a rigorous eval harness baked into the loop, you're swapping one unknown for another. The SOC 2 cert is good but the methodology needs more transparency.”
“GitHub star velocity is often disconnected from production utility. This is a weekend project layered on top of a rapidly changing CLI tool — OpenAI can deprecate or change Codex CLI's interface at any point and OMX breaks. I'd wait for 3-6 months of stability before building workflows on it.”
“LLM apps are entering the maintenance and reliability phase — the 'build it and see' era is over. Systematic failure analysis with auto-generated remediation is the natural next layer of the stack. Kelet is early, but the category is real and it will be important infrastructure within 18 months.”
“This is what the oh-my-zsh moment for AI dev tooling looks like. A community-built orchestration standard that becomes the default way developers manage coding agents could define the category. Early adoption of the right abstraction matters.”
“If you've shipped a chatbot or AI writing tool and are drowning in 'the bot said something weird' support tickets, Kelet is the triage system you didn't know you needed. Finding which prompt variant is responsible for the weirdness has historically been a manual nightmare.”
“Even as a non-backend developer, having 33 pre-built specialized prompts that I can trigger with hooks is genuinely accessible. It lowers the bar to using AI coding agents without needing to be a prompt engineer. Fun and practical.”
