Platforms

ECC keeps standards, workflows, and security policy portable across the harnesses teams already use.

Keep install policy, skills, and review workflow consistent across Claude Code, Codex, Cursor, OpenCode, and the GitHub App without forcing a team onto one editor or one vendor surface.

Claude Code deepest workflow depth
Codex app + CLI parity
Cursor OSS config compatibility
OpenCode portable install path

Claude Code

The deepest ECC surface today: skills, hooks, commands, continuous learning, and the most mature workflow customization.

Codex

Strong support for shared skills, reusable commands, and consistent workflows across app and CLI usage.

Cursor

Supported through the OSS install path so teams can keep shared conventions, coding standards, and security checks without maintaining a parallel stack.

OpenCode

An important open harness target for portable config, adapters, and cross-tool workflow packaging.

Verified install surfaces today
  • GitHub App for repo-native onboarding and reviewable PRs
  • ecc-universal on npm for OSS installs
  • ecc-agentshield on npm for security scans
  • GitHub Marketplace action for AgentShield CI scanning
Parity roadmap
  • Selective install profiles that remain portable across harnesses
  • Shared policy and security review concepts above the individual tool
  • Common skill, agent, and workflow packaging
  • Operator visibility through ECC 2.0 control-plane work
Current install flow

Start with the selective install builder for OSS harnesses, then add the GitHub App when you want repo-native guidance, team review, and active-seat billing.

oss install
$ npm i -g ecc-universal
Pick core, developer, security, or full in the selective install builder.
Generate harness-specific config for Claude Code, Codex, Cursor, and OpenCode from one shared profile.
Security layer

Add AgentShield when you need the same config and workflow review model to follow the team across tools, not just inside one editor.

Start with ECC

Move from OSS discovery to repo-native rollout.

The ECC model stays additive: open-source distribution first, GitHub App automation when repository workflows matter, and enterprise support when the organization needs policy, rollout help, and governance.
