DevPlane
Two products in one project. (1) A local cockpit for multi-tool software development — assignment registry, two-phase actor handoff, coordination-event log, MCP server, CLI, Chrome extension; the operator-side measurement layer AI coding tools' agent-side metrics miss. (2) The portfolio's shared engineering brain — pattern library, architecture maps, session handoffs, cross-project assignment registry, API registry, decision log, capabilities catalog, and the capability-architecture doctrine the whole portfolio is built against.
Two convergent problems. AI coding tools' productivity claims rest on agent-side measurements — lines produced, tasks completed, time-to-PR. If the Ironies of Automation are operative (operator vigilance falling as agent reliability rises), those measurements systematically overstate net effect. There is no operator-side cockpit catching the loss. And on the portfolio side, every repo accumulates its own patterns, architecture maps, handoffs, and decisions — most of which are unreachable from any other repo. The result is rebuilding the same primitive five times across five products and not noticing.
A local dashboard + MCP server + CLI + Chrome extension that orchestrates day-to-day work inside one target project (kanban, actions, dispatch, session reports). A multi-agent kanban with a completion-block protocol that tracks per-card execution across heterogeneous AI tools. Two-phase actor handoff (builder → reviewer) where the second transition requires an artifact only the reviewer can produce. Cross-tool sync via a hub SDK so an operator coordinates Cursor, Claude Code, Replit, and other agents through one board. The continuous production telemetry that runs the C1 risk-compensation field study — a pre-registered test of Bainbridge 1983 in real coding work, with hypotheses, analysis plan, and falsification criteria specified before data accumulates. The cross-project documentation hub: pattern library (~20 production-validated patterns), architecture maps per repo, session-handoff archive, assignment registry across repos, API registry, decision log, capabilities catalog, and the Portfolio Capability Platform Playbook that governs how every product folder is structured (src/capabilities/<name>/{contracts,core,adapters,ui,tests} with extraction maturity levels 0–3). Performix is the first reference implementation of the doctrine.
- 01Two-phase actor handoff (builder → reviewer) where the second transition requires an artifact only the reviewer can produce — enforces review without trusting it
- 02Coordination-event log as a research instrument, not just an audit trail — the apparatus for the C1 risk-compensation field study
- 03Completion blocks as a protocol — every assignment ends with structured machine-readable completion, not free-text close-out
- 04Hub-and-spoke sync between heterogeneous AI tools so an operator coordinates Cursor + Claude Code + Replit + custom agents through one board
- 05Cross-project documentation hub — patterns, maps, handoffs, assignments, APIs, decisions, and capabilities legible across every repo in the portfolio. Reduces the rebuild-it-five-times tax that solo-cadence multi-product work would otherwise pay.
- 06Capability Architecture Doctrine — the portfolio-wide playbook for structuring applications as compositions of extractable capabilities with contracts, adapters, and props-driven UI. Performix is the first reference implementation; subsequent products inherit the structure.
Private. The operator-side coordination spine for the multi-app portfolio. Live locally, measuring, instrumented for the C1 field study. Productising as a multi-tenant SaaS per docs/DEVPLANE-ROADMAP.md. Portfolio consolidation plan in flight: 5 clusters + DevPlane (Fantasy Football absorbs mfl-command-center; namesake/ monorepo absorbs baby-namer family; etc.). Pattern library ships ~20 reusable patterns; capability doctrine is the architectural framework for everything built going forward.
DevPlane is two bets in one project. The first bet is operator-side: the productivity claims being made for AI coding tools are largely grounded in agent-side measurements — and those measurements systematically miss what an operator running multiple agents actually has to do. Build the cockpit, instrument it, run the pre-registered field study against the agents-on-tap-make-everyone-faster claim, and either the data validates or qualifies it. Either way it is more honest than what the field has today. The second bet is shared-brain: every repo in this portfolio accumulates its own patterns, maps, handoffs, and decisions — and most of them stay locked inside the repo that produced them. DevPlane's cross-project documentation role pulls those into one legible surface so the next product can stand on the last one's shoulders rather than rebuilding from scratch. The two bets reinforce each other: the cockpit collects the telemetry that the shared-brain layer turns into pattern recommendations across products.
