Cole Medin
Cole's gone full dark factory — AI writing code, reviewing its own PRs, merging, and looping, and he's building it live on Archon so you can steal the workflow.

Building an AI Dark Factory: A Codebase That Writes Its Own Code, Live
AI writes, reviews, and merges its own code
Watch this if you want to see how Archon can orchestrate a fully autonomous code-ship loop — directly relevant to leveling up mx-workflow's automation.
details
What it is: A livestream where Cole builds a "dark factory" — a system where an AI coding agent writes code, opens PRs, reviews them itself, merges, and loops back for the next task, with zero human code review.
How it works:
- Built on top of Archon, Cole's open-source harness builder for AI coding
- Archon workflows are node-based: each node is either a prompt sent to a coding agent session or a deterministic command (validation, testing, context curation)
- The dark factory chains these nodes into an autonomous loop: plan → implement → test → review → merge → repeat
- Human approval gates are optional — Cole is deliberately removing them to test full autonomy
- Archon handles orchestration, parallel agent sessions, and logging so you can monitor what's happening
Tools & links:
- Archon — open-source harness builder for AI coding agents, the core engine behind the dark factory
- Archon workflows — prepackaged workflows for fixing GitHub issues, creating PRs from ideas, PR validation/review, and PRD generation with human-in-the-loop
- Archon ships as a Claude Code plugin with a built-in skill — say "use archon to build this feature" and it picks the right workflow
How mx-workflow could steal from this:
- Archon's node-based workflow model (prompt nodes + deterministic command nodes) is a more structured version of what mx-workflow does with slash commands — consider whether mx-workflow commands could be composed into repeatable, chainable workflows
- The dark factory pattern (write → test → review → merge → loop) is essentially `/mx:shipit` on autopilot — Archon adds the orchestration layer that makes that loop autonomous
- Archon's approach of enforcing deterministic validation steps (not leaving linting/testing to the agent's discretion) directly mirrors mx-workflow's `/mx:validate` philosophy but makes it structural rather than optional
- Worth studying how Archon separates "things the agent decides" from "things the harness enforces" — that distinction is the whole game for reliable AI coding

GLM-5.1 is open-weight, MIT-licensed, and outscoring GPT-5.4 and Opus 4.6 on SWEBench — you could fine-tune this for your own coding workflows today.

Insane Open Source AI Model Just Dropped
GLM-5.1 beats GPT-5.4 at coding, open-weight
Watch this if you want to run a frontier-class coding model locally or fine-tune one specifically for your web app stack — MIT license means no strings.
details
What it is: GLM-5.1 from Z.ai (Zhipu AI), an open-weight model released under the MIT license that's outperforming GPT-5.4 and Opus 4.6 on software engineering benchmarks.
Benchmarks that matter:
- SWEBench Pro (real-world software engineering): GLM-5.1 scores 58.4 vs GPT-5.4's 57.7 and Opus 4.6's 57.3
- Beating closed-source frontier models while being fully downloadable is the headline
Why this matters for web app builders:
- MIT license = download, fine-tune, run locally, embed in your pipeline, no usage fees
- Available on HuggingFace right now — model weights are public
- You could fine-tune this on your own codebase patterns (SvelteKit, Supabase, your conventions) and get a coding model that knows your stack intimately
- Potential to plug into local AI coding setups alongside tools like Archon or Claude Code as an alternative model backend
Tools & links:
- GLM-5.1 on HuggingFace — THUDM is Zhipu's HuggingFace org, search for GLM-5.1 weights
- Z.ai (Zhipu AI) — the Chinese AI lab behind the model
Bottom line: The gap between open-weight and closed-source models on coding tasks is effectively zero now. If you're building web apps and paying per token, this changes the math.
What Shipped
claude-code
Thinking hints, worktree paths, plugin monitors, WebFetch upgrade.
Plugin monitors, PreCompact hooks, and smarter WebFetch make Claude Code more capable as an automation backbone for your app-building workflow.
details
What changed (v2.1.105–v2.1.107):
- `EnterWorktree` now accepts a `path` param to switch into an existing worktree
- PreCompact hook support — hooks can block compaction (exit code 2 or `{"decision":"block"}`)
- Background monitors for plugins via top-level `monitors` manifest key, auto-armed at session start
- `/proactive` is now an alias for `/loop`
- Stalled API streams abort after 5 min of no data and retry non-streaming
- WebFetch strips `<style>` and `<script>` so CSS-heavy pages no longer exhaust the content budget
- Stale agent worktrees from squash-merged PRs are now auto-cleaned
- Thinking hints shown sooner during long operations (v2.1.107)
- Skill description listing cap raised from 250 → 1,536 chars
- `/doctor` now shows status icons; press `f` to auto-fix issues
Bug fixes (notable):
- Images on queued messages no longer dropped
- Fixed blank screen when prompt wraps to second line
- Fixed alt+enter / Ctrl+J newline regression
- Fixed one-shot scheduled tasks re-firing repeatedly
- Fixed marketplace auto-update breaking when plugin processes hold files open
- Fixed leading whitespace trimming that broke ASCII art
Breaking changes:
- None
Links:
Why it matters for you: Plugin monitors and PreCompact hooks give you deeper control over Claude Code automation, and the WebFetch fix directly improves scraping reliability for workflows like mx-brief.
Supabase
Stripe Sync Engine donated to Stripe's GitHub org.
If you use Supabase + Stripe (like mx-au-mane), the sync engine now lives under Stripe's official maintenance — more stable long-term.
details
What changed:
- The Stripe Sync Engine, originally built by Supabase to sync Stripe data into Postgres, has been donated to the Stripe GitHub org
- This means Stripe now officially maintains the project
Breaking changes:
- None announced, but the repo URL will change — update any references if you depend on the Supabase fork
Links:
Why it matters for you: For mx-au-mane's finance tracking with Supabase + Stripe, having the sync engine under Stripe's official stewardship means better long-term support and tighter integration.
