Changelog
Every change on modernEngineer: new pieces and updated pieces.
- Setting up Cloud Harness MCP on your own domain + ChatGPT
Deploy Cloud Harness MCP to a VPS, gate the hostname with Cloudflare Access, turn on Managed OAuth, then wire up the ChatGPT connector. With 21 real screenshots, identifying data blurred.
- Inside OMP #3: the Advisor is not just a second model
The Advisor is a supervisory control loop running alongside the main agent in the same session, not a stronger model called in to give an opinion.
- OMP Plan mode and AgentKit ak:plan: same word plan, different operating layer
OMP /plan locks the runtime read-only, AgentKit ak:plan produces a durable file-backed roadmap. When to use which, and why not to nest the two workflows.
- Imagegen: 7 design directions for on-style images
Install the imagegen skill, pick one of seven visual directions, and generate infographics that stay on content.
- Install AgentKit from the control plane — stable/beta
Do not copy the kit into every project. The manifest picks a channel; the control plane keeps immutable releases.
- cmux SKILL family — operating map
One entry point routes every cmux request. Identity before mutation. Additive layout with --focus false.
- Use the Codex app as an agent coordination hub
Run several Codex threads in parallel, each in its own worktree, with paste-ready prompts.
- Controlled cross-runtime AI skills management
Import, adapt, link, and retire AI skills across runtimes without losing provenance.
- Install Subscriber Skills via CLI
- Working with Fable 5: fix the map before entering the territory
The distance between prompt and codebase is unknowns. A six-stage pipeline, three fixed gates around ck:cook, and the cost of choosing a model per stage.
- When to use /ck:plan --deep --tdd
--deep helps the plan see the full scope, --tdd adds a regression gate for refactors. When each option pays off, and when you can skip them.
