The performance optimization system for AI agent harnesses. From an Anthropic hackathon winner.

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 Claude Code, Codex, Cursor, OpenCode, Gemini, and other AI agent harnesses.

What's New

v1.10.0 — 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: 38 agents, 156 skills, and 72 legacy command shims.
  • Operator and outbound workflow expansionbrand-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 toolingmanim-video, remotion-video-creation, and upgraded social publishing surfaces make technical explainers and launch content part of the same system.
  • Framework and product surface growthnestjs-patterns, richer Codex/OpenCode install surfaces, and expanded cross-harness packaging keep the repo usable beyond Claude Code alone.
  • 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.
  • 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.
  • 6 new agentstypescript-reviewer, pytorch-build-resolver, java-build-resolver, java-reviewer, kotlin-reviewer, kotlin-build-resolver expand language coverage to 10 languages.
  • New skillspytorch-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 controlsECC_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.
  • 997 internal tests passing — full suite green after hook/runtime refactor and compatibility updates.

v1.7.0 — Cross-Platform Expansion & Presentation Builder (Feb 2026)

  • Codex app + CLI support — Direct AGENTS.md-based Codex support, installer targeting, and Codex docs
  • frontend-slides skill — Zero-dependency HTML presentation builder with PPTX conversion guidance and strict viewport-fit rules
  • 5 new generic business/content skillsarticle-writing, content-engine, market-research, investor-materials, investor-outreach
  • Broader tool coverage — Cursor, Codex, and OpenCode support tightened so the same repo ships cleanly across all major harnesses
  • 992 internal tests — Expanded validation and regression coverage across plugin, hooks, skills, and packaging

v1.6.0 — Codex CLI, AgentShield & Marketplace (Feb 2026)

  • Codex CLI support — New /codex-setup command generates codex.md for OpenAI Codex CLI compatibility
  • 7 new skillssearch-first, swift-actor-persistence, swift-protocol-di-testing, regex-vs-llm-structured-text, content-hash-cache-pattern, cost-aware-llm-pipeline, skill-stocktake
  • AgentShield integration/security-scan skill runs AgentShield directly from Claude Code; 1282 tests, 102 rules
  • GitHub Marketplace — ECC Tools GitHub App live at github.com/marketplace/ecc-tools with free/pro/enterprise tiers
  • 30+ community PRs merged — Contributions from 30 contributors across 6 languages

Quick Start

Get up and running in under 2 minutes:

Step 1: Install the Plugin

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/everything-claude-code

# Install plugin
/plugin install everything-claude-code@everything-claude-code

Naming + Migration Note

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

  • GitHub source repo: affaan-m/everything-claude-code
  • Claude marketplace/plugin identifier: everything-claude-code@everything-claude-code
  • npm package: ecc-universal

This is intentional. Anthropic marketplace/plugin installs are keyed by a canonical plugin identifier, so ECC standardized on everything-claude-code@everything-claude-code to keep the listing name, /plugin install, /plugin list, and repo docs aligned to one public install surface. Older posts may still show the old short-form nickname; that shorthand is deprecated. Separately, the npm package stayed on ecc-universal, so npm installs and marketplace installs intentionally use different names.

Step 2: Install Rules (Required)

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. 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 ecc list-installed, then run ecc doctor and ecc 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

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

# Plugin install path: copy only rules
mkdir -p ~/.claude/rules
cp -R rules/common ~/.claude/rules/
cp -R rules/typescript ~/.claude/rules/
