Project mention: The AI Harness: why your AI coding agent is only as smart as the repo you put it in | dev.to | 2026-05-01Hi. I am an engineer at Activepieces, an open source automation platform (think Zapier, but you can self host it and read the source code). I write TypeScript for a living. I argue with bots about tabs vs spaces now. And our team spent the last few months really, really invested in one question:

That's when I thought, why not use the Cloudflare Agent SDK to build an agent. I started building my agent with custom functions to handle audio input and output. The M5Stack would connect to the agent deployed on the edge, send the audio chunks, the agent would process this, perform the action, and stream the audio response back to the device. This was working fine, but it was a lot of code, fragile code. If I switched the Text-To-Speech (TTS) or Speech-To-Text(STT) models, I would have to update the code to handle encoding, and decoding. This wasn't fun at all.

cognetivy
The open-source state layer for AI coding agents. Turn chaotic agent sessions into structured, traceable workflows with a local workspace for runs, events, and collections.
Project mention: Just crossed 2k NPM downloads and shipped the biggest Cognetivy upgrade yet | news.ycombinator.com | 2026-03-09Most general-purpose coding agents (Cursor, Claude Code, etc.) are powerful, but in real jobs not rekated to necessarily to code (researches, creating content, etc.) they can feel random: different structure each run, unclear execution state, weak traceability.
That’s exactly why Cognetivy was built:
Website: https://cognetivy.com
Repo: https://github.com/meitarbe/cognetivy
We just crossed 2,000+ npm downloads, and shipped a major upgrade focused on one core thing which is making agent execution more deterministic and structured.
What that means in practice?
• Clear workflow DAGs (instead of free-form drift)
• Deterministic next-step/run-state guidance
• Better handling of parallel steps
• Schema-backed collections for structured outputs
• Built-in traceability fields (citations, derived_from, reasoning)
• Validation guardrails (including cycle prevention)
• Faster setup via templates + auto schema generation
Cognetivy is our way of adding that execution backbone on top of general-purpose agents.
I’d love to hear where determinism still breaks for you and also Im looking to partner if someone interested to collaborate.
