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 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.
• 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 agents — typescript-reviewer, pytorch-build-resolver, java-build-resolver, java-reviewer, kotlin-reviewer, kotlin-build-resolver expand language coverage to 10 languages.
• 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.
• 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 skills — article-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 skills — search-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
• 978 internal tests — Expanded validation suite across agents, skills, commands, hooks, and rules

v1.4.1 — Bug Fix (Feb 2026)

• Fixed instinct import content loss — parse_instinct_file() was silently dropping all content after frontmatter (Action, Evidence, Examples sections) during /instinct-import. (#148, #161)

v1.4.0 — Multi-Language Rules, Installation Wizard & PM2 (Feb 2026)

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
git clone https://github.com/affaan-m/everything-claude-code.git
cd everything-claude-code

# 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/

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

# Windows PowerShell

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

# 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.

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 namespaced form
/ecc:plan "Add user authentication"

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

# Check available commands
/plugin list everything-claude-code@everything-claude-code

That's it! You now have access to 48 agents, 183 skills, and 79 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, 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:

1. Environment variable: CLAUDE_PACKAGE_MANAGER
2. Project config: .claude/package-manager.json
3. package.json: packageManager field
4. Lock file: Detection from package-lock.json, yarn.lock, pnpm-lock.yaml, or bun.lockb
5. Global config: ~/.claude/package-manager.json
6. 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"
