ECC v2.0.0-rc.1 Release Notes

Positioning

ECC v2.0.0-rc.1 is the first release-candidate surface for ECC as a cross-harness operating system for agentic work.

Claude Code remains a core target. Codex, OpenCode, Cursor, Gemini, and other harnesses are treated as execution surfaces that can share the same skills, rules, MCP conventions, and operator workflows. ECC is the reusable substrate; Hermes is documented as the operator shell that can sit on top of that layer.

What Changed

Added the sanitized Hermes setup guide to the public release story.
Added launch collateral in-repo so the release can ship from one reviewed surface.
Clarified the split between ECC as the reusable substrate and Hermes as the operator shell.
Documented the cross-harness portability model for skills, hooks, MCPs, rules, and instructions.
Added a Hermes import playbook for turning local operator patterns into publishable ECC skills.

Why This Matters

ECC is no longer only a Claude Code plugin or config bundle.

The system now has a clearer shape:

reusable skills instead of one-off prompts
hooks and tests for workflow discipline
MCP-backed access to docs, code, browser automation, and research
cross-harness install surfaces for Claude Code, Codex, OpenCode, Cursor, and related tools
Hermes as an optional operator shell for chat, cron, handoffs, and daily work routing

Release Candidate Boundaries

This is a release candidate, not the final GA claim.

What ships in this surface:

public Hermes setup documentation
release notes and launch collateral
cross-harness architecture documentation
Hermes import guidance for sanitized operator workflows

What stays local:

secrets, OAuth tokens, and API keys
private workspace exports
personal datasets
operator-specific automations that have not been sanitized
deeper CRM, finance, and Google Workspace playbooks

Upgrade Motion

Read the Hermes setup guide.
Review the cross-harness architecture.
Start with one workflow lane: engineering, research, content, or outreach.
Import only sanitized operator patterns into ECC skills.
Treat ecc2/ as an alpha control plane until release packaging and installer behavior are finalized.
