The harness-native operator system for agentic work. Built from real-world multi-harness engineering workflows.

Not just configs. A complete system: skills, instincts, memory optimization, continuous learning, security scanning, and research-first development. Production-ready agents, skills, hooks, rules, MCP configurations, and legacy command shims evolved over 10+ months of intensive daily use building real products.

Works across Codex, Claude Code, Cursor, OpenCode, Gemini, Zed, GitHub Copilot, and other AI agent harnesses.

ECC v2.0.0 adds the public Hermes operator story on top of that reusable layer: start with the Hermes setup guide, then review the 2.0.0 release notes and cross-harness architecture.

OSS stays free. This repo is MIT-licensed forever. ECC Pro is the hosted GitHub App for private repos. Sponsors and Pro subscribers fund the work — that's why a single maintainer ships weekly across 7 harnesses.

What's New

v2.0.0 — The Agent Harness Operating System (Jun 2026)

Stable graduation of the 2.0 line: 261 skills, the control-pane substrate (session adapters + MCP inventory), the worktree-lifecycle service, the orch-* orchestrator family, and the launch of the ECC Discord community. Full notes: docs/releases/2.0.0/release-notes.md.

v2.0.0-rc.1 — Surface Refresh, Operator Workflows, and ECC 2.0 Alpha (Apr 2026)

Dashboard GUI — New Tkinter-based desktop application (ecc_dashboard.py or npm run dashboard) with dark/light theme toggle, font customization, and project logo in header and taskbar.
Public surface synced to the live repo — metadata, catalog counts, plugin manifests, and install-facing docs now match the actual OSS surface: 66 agents, 268 skills, and 84 legacy command shims.
Operator and outbound workflow expansion — brand-voice, social-graph-ranker, connections-optimizer, customer-billing-ops, ecc-tools-cost-audit, google-workspace-ops, project-flow-ops, and workspace-surface-audit round out the operator lane.
Media and launch tooling — manim-video, remotion-video-creation, and upgraded social publishing surfaces make technical explainers and launch content part of the same system.
Framework and product surface growth — nestjs-patterns, richer Codex/OpenCode install surfaces, and expanded cross-harness packaging keep the repo usable beyond Claude Code alone.
Itô prediction-market skill pack — ito-market-intelligence, ito-basket-compare, ito-trade-planner, ito-data-atlas-agent, prediction-market-oracle-research, and prediction-market-risk-review add public, non-advisory market/basket workflows while keeping live Itô API access gated and separate from ECC Tools billing.
Optimization skill pack — parallel-execution-optimizer, benchmark-optimization-loop, data-throughput-accelerator, latency-critical-systems, and recursive-decision-ledger turn repeated speed/recursion prompts into bounded benchmark, throughput, and decision-ledger workflows.
ECC 2.0 alpha is in-tree — the Rust control-plane prototype in ecc2/ now builds locally and exposes dashboard, start, sessions, status, stop, resume, and daemon commands. It is usable as an alpha, not yet a general release.
Operator status snapshots — ecc status --markdown --write status.md turns the local state store into a portable handoff covering readiness, active sessions, skill-run health, install health, pending governance events, and linked work items from Linear/GitHub/handoffs. Use ecc work-items upsert ... for manual entries, ecc work-items sync-github --repo owner/repo for PR/issue queue state, and ecc status --exit-code to fail automation when readiness needs attention.
Ecosystem hardening — AgentShield, ECC Tools cost controls, billing portal work, and website refreshes continue to ship around the core plugin instead of drifting into separate silos.

v1.9.0 — Selective Install & Language Expansion (Mar 2026)

Selective install architecture — Manifest-driven install pipeline with install-plan.js and install-apply.js for targeted component installation. State store tracks what's installed and enables incremental updates.

New skills — pytorch-patterns for deep learning workflows, documentation-lookup for API reference research, bun-runtime and nextjs-turbopack for modern JS toolchains, plus 8 operational domain skills and mcp-server-patterns.
Session & state infrastructure — SQLite state store with query CLI, session adapters for structured recording, skill evolution foundation for self-improving skills.
Orchestration overhaul — Harness audit scoring made deterministic, orchestration status and launcher compatibility hardened, observer loop prevention with 5-layer guard.
Observer reliability — Memory explosion fix with throttling and tail sampling, sandbox access fix, lazy-start logic, and re-entrancy guard.
12 language ecosystems — New rules for Java, PHP, Perl, Kotlin/Android/KMP, C++, and Rust join existing TypeScript, Python, Go, and common rules.
Community contributions — Korean and Chinese translations, biome hook optimization, video processing skills, operational skills, PowerShell installer, Antigravity IDE support.
CI hardening — 19 test failure fixes, catalog count enforcement, install manifest validation, and full test suite green.

v1.8.0 — Harness Performance System (Mar 2026)

Harness-first release — ECC is now explicitly framed as an agent harness performance system, not just a config pack.
Hook reliability overhaul — SessionStart root fallback, Stop-phase session summaries, and script-based hooks replacing fragile inline one-liners.
Hook runtime controls — ECC_HOOK_PROFILE=minimal|standard|strict and ECC_DISABLED_HOOKS=... for runtime gating without editing hook files.
New harness commands — /harness-audit, /loop-start, /loop-status, /quality-gate, /model-route.
NanoClaw v2 — model routing, skill hot-load, session branch/search/export/compact/metrics.
Cross-harness parity — behavior tightened across Claude Code, Cursor, OpenCode, and Codex app/CLI.

Quick Start

Get up and running in under 2 minutes:

Pick one path only

Most Claude Code users should use exactly one install path:

Recommended default: install the Claude Code plugin, then copy only the rule folders you actually want.
Use the manual installer only if you want finer-grained control, want to avoid the plugin path entirely, or your Claude Code build has trouble resolving the self-hosted marketplace entry.
Do not stack install methods. The most common broken setup is: /plugin install first, then install.sh --profile full or npx ecc-install --profile full afterward.

If you already layered multiple installs and things look duplicated, skip straight to Reset / Uninstall ECC.

Low-context / no-hooks path

If hooks feel too global or you only want ECC's rules, agents, commands, and core workflow skills, skip the plugin and use the minimal manual profile:

./install.sh --profile minimal --target claude

.\install.ps1 --profile minimal --target claude
# or
npx ecc-install --profile minimal --target claude

This profile intentionally excludes hooks-runtime.

If you want the normal core profile but need hooks off, use:

./install.sh --profile core --without baseline:hooks --target claude

Add hooks later only if you want runtime enforcement:

./install.sh --target claude --modules hooks-runtime

Find the right components first

If you are not sure which ECC profile or component to install, ask the packaged advisor from any project:

npx ecc consult "security reviews" --target claude

It returns matching components, related profiles, and preview/install commands. Use the preview command before installing if you want to inspect the exact file plan.

For production ML/MLOps workflows, keep the install opt-in and component-scoped:

npx ecc consult "mlops training model deployment" --target claude
npx ecc install --profile minimal --target claude --with capability:machine-learning

Step 1: Install the Plugin (Recommended)

NOTE: The plugin is convenient, but the OSS installer below is still the most reliable path if your Claude Code build has trouble resolving self-hosted marketplace entries.

# Add marketplace
/plugin marketplace add https://github.com/affaan-m/ECC

# Install plugin
/plugin install ecc@ecc

Naming + Migration Note

ECC now has three public identifiers, and they are not interchangeable:

GitHub source repo: affaan-m/ECC
Claude marketplace/plugin identifier: ecc@ecc
npm package: ecc-universal

This is intentional. Anthropic marketplace/plugin installs are keyed by a canonical plugin identifier, so ECC uses ecc@ecc to keep tool names and slash-command namespaces short enough for strict Desktop/API validators. Older posts may still show the former long marketplace identifier; treat that as a legacy alias only. Separately, the npm package stayed on ecc-universal, so npm installs and marketplace installs intentionally use different names.

Step 2: Install Rules Only If You Need Them

WARNING: Important: Claude Code plugins cannot distribute rules automatically.

If you already installed ECC via /plugin install, do not run ./install.sh --profile full, .\install.ps1 --profile full, or npx ecc-install --profile full afterward. The plugin already loads ECC skills, commands, and hooks. Running the full installer after a plugin install copies those same surfaces into your user directories and can create duplicate skills plus duplicate runtime behavior.

For plugin installs, manually copy only the rules/ directories you want under ~/.claude/rules/ecc/. Start with rules/common plus one language or framework pack you actually use. Do not copy every rules directory unless you explicitly want all of that context in Claude.

Use the full installer only when you are doing a fully manual ECC install instead of the plugin path.

If your local Claude setup was wiped or reset, that does not mean you need to repurchase ECC. Start with node scripts/ecc.js list-installed, then run node scripts/ecc.js doctor and node scripts/ecc.js repair before reinstalling anything. That usually restores ECC-managed files without rebuilding your setup. If the problem is account or marketplace access for ECC Tools, handle billing/account recovery separately.

# Clone the repo first
git clone https://github.com/affaan-m/ECC.git
cd ECC

# Install dependencies (pick your package manager)
npm install        # or: pnpm install | yarn install | bun install

# Plugin install path: copy only ECC rules into an ECC-owned namespace
mkdir -p ~/.claude/rules/ecc
cp -R rules/common ~/.claude/rules/ecc/
cp -R rules/typescript ~/.claude/rules/ecc/

# Fully manual ECC install path (use this instead of /plugin install)
# ./install.sh --profile full

# Windows PowerShell

# Plugin install path: copy only ECC rules into an ECC-owned namespace
New-Item -ItemType Directory -Force -Path "$HOME/.claude/rules/ecc" | Out-Null
Copy-Item -Recurse rules/common "$HOME/.claude/rules/ecc/"
Copy-Item -Recurse rules/typescript "$HOME/.claude/rules/ecc/"

# Fully manual ECC install path (use this instead of /plugin install)
# .\install.ps1 --profile full
# npx ecc-install --profile full

For manual install instructions see the README in the rules/ folder. When copying rules manually, copy the whole language directory (for example rules/common or rules/golang), not the files inside it, so relative references keep working and filenames do not collide.

Fully manual install (Fallback)

Use this only if you are intentionally skipping the plugin path:

./install.sh --profile full

.\install.ps1 --profile full
# or
npx ecc-install --profile full

If you choose this path, stop there. Do not also run /plugin install.

Reset / Uninstall ECC

If ECC feels duplicated, intrusive, or broken, do not keep reinstalling it on top of itself.

Plugin path: remove the plugin from Claude Code, then delete the specific rule folders you manually copied under ~/.claude/rules/ecc/.
Manual installer / CLI path: from the repo root, preview removal first:

node scripts/uninstall.js --dry-run

Then remove ECC-managed files:

node scripts/uninstall.js

You can also use the lifecycle wrapper:

node scripts/ecc.js list-installed
node scripts/ecc.js doctor
node scripts/ecc.js repair
node scripts/ecc.js uninstall --dry-run

ECC only removes files recorded in its install-state. It will not delete unrelated files it did not install.

If you stacked methods, clean up in this order:

Remove the Claude Code plugin install.
Run the ECC uninstall command from the repo root to remove install-state-managed files.
Delete any extra rule folders you copied manually and no longer want.
Reinstall once, using a single path.

Step 3: Start Using

# Skills are the primary workflow surface.
# Existing slash-style command names still work while ECC migrates off commands/.

# Plugin install uses the canonical namespaced form
/ecc:plan "Add user authentication"

# Manual install keeps the shorter slash form:
# /plan "Add user authentication"

# Check available commands
/plugin list ecc@ecc

That's it! You now have access to 67 agents, 278 skills, and 94 legacy command shims.

Dashboard GUI

Launch the desktop dashboard to visually explore ECC components:

npm run dashboard
# or
python3 ./ecc_dashboard.py

Features:

Tabbed interface: Agents, Skills, Commands, Rules, Settings
Dark/Light theme toggle
Font customization (family & size)
Project logo in header and taskbar
Search and filter across all components

Multi-model commands require additional setup

WARNING: multi-* commands are not covered by the base plugin/rules install above.

To use /multi-plan, /multi-execute, /multi-backend, /multi-frontend, and /multi-workflow, you must also install the ccg-workflow runtime.

Initialize it with npx ccg-workflow.

That runtime provides the external dependencies these commands expect, including:

~/.claude/bin/codeagent-wrapper

~/.claude/.ccg/prompts/*

Without ccg-workflow, these multi-* commands will not run correctly.

Cross-Platform Support

This plugin now fully supports Windows, macOS, and Linux, alongside tight integration across major IDEs (Cursor, Zed, OpenCode, Antigravity) and CLI harnesses. All hooks and scripts have been rewritten in Node.js for maximum compatibility.

Package Manager Detection

The plugin automatically detects your preferred package manager (npm, pnpm, yarn, or bun) with the following priority:

Environment variable: CLAUDE_PACKAGE_MANAGER
Project config: .claude/package-manager.json
package.json: packageManager field
Lock file: Detection from package-lock.json, yarn.lock, pnpm-lock.yaml, or bun.lockb
Global config: ~/.claude/package-manager.json
Fallback: First available package manager

To set your preferred package manager:

# Via environment variable
export CLAUDE_PACKAGE_MANAGER=pnpm

# Via global config
node scripts/setup-package-manager.js --global pnpm

# Via project config
node scripts/setup-package-manager.js --project bun

# Detect current setting
node scripts/setup-package-manager.js --detect

Or use the /setup-pm command in Claude Code.

Hook Runtime Controls

Use runtime flags to tune strictness or disable specific hooks temporarily:

# Hook strictness profile (default: standard)
export ECC_HOOK_PROFILE=standard

# Comma-separated hook IDs to disable
export ECC_DISABLED_HOOKS="pre:bash:tmux-reminder,post:edit:typecheck"

# Cap SessionStart additional context (default: 8000 chars)
export ECC_SESSION_START_MAX_CHARS=4000

# Disable SessionStart additional context entirely for low-context/local-model setups
export ECC_SESSION_START_CONTEXT=off

# Session-tmp retention window in days (default: 30).
# Set to 0, off, false, disabled, never, or none to keep all sessions (disable pruning).
export ECC_SESSION_RETENTION_DAYS=14

# Cap how many learned instincts SessionStart injects into context (default: 6)
export ECC_MAX_INJECTED_INSTINCTS=6

# Minimum confidence an instinct needs to be injected, 0-1 (default: 0.7)
export ECC_INSTINCT_CONFIDENCE_THRESHOLD=0.7

# Keep context/scope/loop warnings but suppress API-rate cost estimates
export ECC_CONTEXT_MONITOR_COST_WARNINGS=off

Windows PowerShell:

[Environment]::SetEnvironmentVariable('ECC_CONTEXT_MONITOR_COST_WARNINGS', 'off', 'User')
[Environment]::SetEnvironmentVariable('ECC_SESSION_RETENTION_DAYS', '14', 'User')

Agent data home (multi-harness isolation)

Memory persistence hooks (session summaries, learned skills, session aliases, metrics) store data under a single agent data root. By default that root is ~/.claude. When you use ECC in both Claude Code and Cursor on the same machine, set a separate root for Cursor so the two environments do not overwrite each other's session files:

# Cursor-only boundary (Claude Code keeps the default ~/.claude)
export ECC_AGENT_DATA_HOME="$HOME/.cursor/ecc"

Paths resolved under that root include:

$ECC_AGENT_DATA_HOME/session-data/ — session summaries
$ECC_AGENT_DATA_HOME/skills/learned/ — learned skills from evaluate-session
$ECC_AGENT_DATA_HOME/session-aliases.json — session aliases
$ECC_AGENT_DATA_HOME/metrics/ — cost and activity metrics
