**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)

- **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](https://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](https://github.com/affaan-m/everything-claude-code/issues/148), [#161](https://github.com/affaan-m/everything-claude-code/pull/161))

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

- **Interactive installation wizard** — New `configure-ecc` skill provides guided setup with merge/overwrite detection
- **PM2 & multi-agent orchestration** — 6 new commands (`/pm2`, `/multi-plan`, `/multi-execute`, `/multi-backend`, `/multi-frontend`, `/multi-workflow`) for managing complex multi-service workflows
- **Multi-language rules architecture** — Rules restructured from flat files into `common/` + `typescript/` + `python/` + `golang/` directories. Install only the languages you need
- **Chinese (zh-CN) translations** — Complete translation of all agents, commands, skills, and rules (80+ files)
- **GitHub Sponsors support** — Sponsor the project via GitHub Sponsors
- **Enhanced CONTRIBUTING.md** — Detailed PR templates for each contribution type

### v1.3.0 — OpenCode Plugin Support (Feb 2026)

- **Full OpenCode integration** — 12 agents, 24 commands, 16 skills with hook support via OpenCode's plugin system (20+ event types)
- **3 native custom tools** — run-tests, check-coverage, security-audit
- **LLM documentation** — `llms.txt` for comprehensive OpenCode docs

### v1.2.0 — Unified Commands & Skills (Feb 2026)

- **Python/Django support** — Django patterns, security, TDD, and verification skills
- **Java Spring Boot skills** — Patterns, security, TDD, and verification for Spring Boot
- **Session management** — `/sessions` command for session history
- **Continuous learning v2** — Instinct-based learning with confidence scoring, import/export, evolution

## 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.

```bash
# Add marketplace
/plugin marketplace add https://github.com/affaan-m/everything-claude-code

# Install plugin
/plugin install ecc@ecc
```

### Step 2: Install Rules (Required)

> WARNING: **Important:** Claude Code plugins cannot distribute `rules` automatically. Install them manually:

```bash
# 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

# macOS/Linux

# Recommended: install everything (full profile)
./install.sh --profile full

# Or install for specific languages only
./install.sh typescript    # or python or golang or swift or php
# ./install.sh typescript python golang swift php
# ./install.sh --target cursor typescript
# ./install.sh --target antigravity typescript
# ./install.sh --target gemini --profile full
```

```powershell
# Windows PowerShell

# Recommended: install everything (full profile)
.\install.ps1 --profile full

# Or install for specific languages only
.\install.ps1 typescript   # or python or golang or swift or php
# .\install.ps1 typescript python golang swift php
# .\install.ps1 --target cursor typescript
# .\install.ps1 --target antigravity typescript
# .\install.ps1 --target gemini --profile full

# npm-installed compatibility entrypoint also works cross-platform
npx ecc-install typescript
```

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

```bash
# 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 ecc@ecc
```

**That's it!** You now have access to 47 agents, 181 skills, and 79 legacy command shims.

### 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:

```bash
# 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:

```bash
# 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"
```

## Ecosystem Tools

### Skill Creator

Two ways to generate Claude Code skills from your repository:

#### Option A: Local Analysis (Built-in)

Use the `/skill-create` command for local analysis without external services:

```bash
/skill-create                    # Analyze current repo
/skill-create --instincts        # Also generate instincts for continuous-learning
```

This analyzes your git history locally and generates SKILL.md files.

#### Option B: GitHub App (Advanced)

For advanced features (10k+ commits, auto-PRs, team sharing):

[Install GitHub App](https://github.com/apps/skill-creator) | [ecc.tools](https://ecc.tools)

```bash
# Comment on any issue:
/skill-creator analyze

# Or auto-triggers on push to default branch
```

Both options create:
- **SKILL.md files** - Ready-to-use skills for Claude Code
- **Instinct collections** - For continuous-learning-v2
- **Pattern extraction** - Learns from your commit history

### AgentShield — Security Auditor

> Built at the Claude Code Hackathon (Cerebral Valley x Anthropic, Feb 2026). 1282 tests, 98% coverage, 102 static analysis rules.

Scan your Claude Code configuration for vulnerabilities, misconfigurations, and injection risks.

```bash
# Quick scan (no install needed)
npx ecc-agentshield scan

# Auto-fix safe issues
npx ecc-agentshield scan --fix

# Deep analysis with three Opus 4.6 agents
npx ecc-agentshield scan --opus --stream

# Generate secure config from scratch
npx ecc-agentshield init
```

**What it scans:** CLAUDE.md, settings.json, MCP configs, hooks, agent definitions, and skills across 5 categories — secrets detection (14 patterns), permission auditing, hook injection analysis, MCP server risk profiling, and agent config review.

**The `--opus` flag** runs three Claude Opus 4.6 agents in a red-team/blue-team/auditor pipeline. The attacker finds exploit chains, the defender evaluates protections, and the auditor synthesizes both into a prioritized risk assessment. Adversarial reasoning, not just pattern matching.

**Output formats:** Terminal (color-graded A-F), JSON (CI pipelines), Markdown, HTML. Exit code 2 on critical findings for build gates.

Use `/security-scan` in Claude Code to run it, or add to CI with the [GitHub Action](https://github.com/affaan-m/agentshield).

[GitHub](https://github.com/affaan-m/agentshield) | [npm](https://www.npmjs.com/package/ecc-agentshield)

### Continuous Learning v2

The instinct-based learning system automatically learns your patterns:

```bash
/instinct-status        # Show learned instincts with confidence
/instinct-import <file> # Import instincts from others
/instinct-export        # Export your instincts for sharing
/evolve                 # Cluster related instincts into skills
```

See `skills/continuous-learning-v2/` for full documentation.

## Requirements

### Claude Code CLI Version

**Minimum version: v2.1.0 or later**

This plugin requires Claude Code CLI v2.1.0+ due to changes in how the plugin system handles hooks.

Check your version:
```bash
claude --version
```

### Important: Hooks Auto-Loading Behavior

> WARNING: **For Contributors:** Do NOT add a `"hooks"` field to `.claude-plugin/plugin.json`. This is enforced by a regression test.

Claude Code v2.1+ **automatically loads** `hooks/hooks.json` from any installed plugin by convention. Explicitly declaring it in `plugin.json` causes a duplicate detection error:

```
Duplicate hooks file detected: ./hooks/hooks.json resolves to already-loaded file
```

**History:** This has caused repeated fix/revert cycles in this repo ([#29](https://github.com/affaan-m/everything-claude-code/issues/29), [#52](https://github.com/affaan-m/everything-claude-code/issues/52), [#103](https://github.com/affaan-m/everything-claude-code/issues/103)). The behavior changed between Claude Code versions, leading to confusion. We now have a regression test to prevent this from being reintroduced.

---

## Installation

### Option 1: Install as Plugin (Recommended)

The easiest way to use this repo - install as a Claude Code plugin:

```bash
# Add this repo as a marketplace
/plugin marketplace add https://github.com/affaan-m/everything-claude-code

# Install the plugin
/plugin install ecc@ecc
```

Or add directly to your `~/.claude/settings.json`:

```json
{
  "extraKnownMarketplaces": {
    "ecc": {
      "source": {
        "source": "github",
        "repo": "affaan-m/everything-claude-code"
      }
    }
  },
  "enabledPlugins": {
    "ecc@ecc": true
  }
}
```

This gives you instant access to all commands, agents, skills, and hooks.

> **Note:** The Claude Code plugin system does not support distributing `rules` via plugins ([upstream limitation](https://code.claude.com/docs/en/plugins-reference)). You need to install rules manually:
>
> ```bash
> # Clone the repo first
> git clone https://github.com/affaan-m/everything-claude-code.git
>
> # Option A: User-level rules (applies to all projects)
> mkdir -p ~/.claude/rules
> cp -r everything-claude-code/rules/common ~/.claude/rules/
> cp -r everything-claude-code/rules/typescript ~/.claude/rules/   # pick your stack
> cp -r everything-claude-code/rules/python ~/.claude/rules/
> cp -r everything-claude-code/rules/golang ~/.claude/rules/
> cp -r everything-claude-code/rules/php ~/.claude/rules/
>
> # Option B: Project-level rules (applies to current project only)
> mkdir -p .claude/rules
> cp -r everything-claude-code/rules/common .claude/rules/
> cp -r everything-claude-code/rules/typescript .claude/rules/     # pick your stack
> ```

---

### Option 2: Manual Installation

If you prefer manual control over what's installed:

```bash
# Clone the repo
git clone https://github.com/affaan-m/everything-claude-code.git

# Copy agents to your Claude config
cp everything-claude-code/agents/*.md ~/.claude/agents/

# Copy rules directories (common + language-specific)
mkdir -p ~/.claude/rules
cp -r everything-claude-code/rules/common ~/.claude/rules/
cp -r everything-claude-code/rules/typescript ~/.claude/rules/   # pick your stack
cp -r everything-claude-code/rules/python ~/.claude/rules/
cp -r everything-claude-code/rules/golang ~/.claude/rules/
cp -r everything-claude-code/rules/php ~/.claude/rules/

# Copy skills first (primary workflow surface)
# Recommended (new users): core/general skills only
cp -r everything-claude-code/.agents/skills/* ~/.claude/skills/
cp -r everything-claude-code/skills/search-first ~/.claude/skills/

# Optional: add niche/framework-specific skills only when needed
# for s in django-patterns django-tdd laravel-patterns springboot-patterns; do
# cp -r everything-claude-code/skills/$s ~/.claude/skills/
# done

# Optional: keep legacy slash-command compatibility during migration
mkdir -p ~/.claude/commands
cp everything-claude-code/commands/*.md ~/.claude/commands/
```

#### Add hooks to settings.json

Copy the hooks from `hooks/hooks.json` to your `~/.claude/settings.json`.

#### Configure MCPs

Copy desired MCP server definitions from `mcp-configs/mcp-servers.json` into your official Claude Code config in `~/.claude/settings.json`, or into a project-scoped `.mcp.json` if you want repo-local MCP access.

If you already run your own copies of ECC-bundled MCPs, set:

```bash
export ECC_DISABLED_MCPS="github,context7,exa,playwright,sequential-thinking,memory"
```

ECC-managed install and Codex sync flows will skip or remove those bundled servers instead of re-adding duplicates.

**Important:** Replace `YOUR_*_HERE` placeholders with your actual API keys.

## Key Concepts

### Agents

Subagents handle delegated tasks with limited scope. Example:

```markdown
---
name: code-reviewer
description: Reviews code for quality, security, and maintainability
tools: ["Read", "Grep", "Glob", "Bash"]
model: opus
---

You are a senior code reviewer...
```

### Skills

Skills are the primary workflow surface. They can be invoked directly, suggested automatically, and reused by agents. ECC still ships `commands/` during migration, but new workflow development should land in `skills/` first.

```markdown
# TDD Workflow

1. Define interfaces first
2. Write failing tests (RED)
3. Implement minimal code (GREEN)
4. Refactor (IMPROVE)
5. Verify 80%+ coverage
```

### Hooks

Hooks fire on tool events. Example - warn about console.log:

```json
{
  "matcher": "tool == \"Edit\" && tool_input.file_path matches \"\\\\.(ts|tsx|js|jsx)$\"",
  "hooks": [{
    "type": "command",
    "command": "#!/bin/bash\ngrep -n 'console\\.log' \"$file_path\" && echo '[Hook] Remove console.log' >&2"
  }]
}
```

### Rules

Rules are always-follow guidelines, organized into `common/` (language-agnostic) + language-specific directories:

```
rules/
  common/          # Universal principles (always install)
  typescript/      # TS/JS specific patterns and tools
  python/          # Python specific patterns and tools
  golang/          # Go specific patterns and tools
  swift/           # Swift specific patterns and tools
  php/             # PHP specific patterns and tools
```

See [`rules/README.md`](rules/README.md) for installation and structure details.

## Which Agent Should I Use?

Not sure where to start? Use this quick reference. Skills are the canonical workflow surface; slash entries below are the compatibility form most users already know.

| I want to... | Use this command | Agent used |
|--------------|-----------------|------------|
| Plan a new feature | `/ecc:plan "Add auth"` | planner |
| Design system architecture | `/ecc:plan` + architect agent | architect |
| Write code with tests first | `/tdd` | tdd-guide |
| Review code I just wrote | `/code-review` | code-reviewer |
| Fix a failing build | `/build-fix` | build-error-resolver |
| Run end-to-end tests | `/e2e` | e2e-runner |
| Find security vulnerabilities | `/security-scan` | security-reviewer |
| Remove dead code | `/refactor-clean` | refactor-cleaner |
| Update documentation | `/update-docs` | doc-updater |
| Review Go code | `/go-review` | go-reviewer |
| Review Python code | `/python-review` | python-reviewer |
| Review TypeScript/JavaScript code | *(invoke `typescript-reviewer` directly)* | typescript-reviewer |
| Audit database queries | *(auto-delegated)* | database-reviewer |

### Common Workflows

Slash forms below are shown because they are still the fastest familiar entrypoint. Under the hood, ECC is shifting these workflows toward skills-first definitions.

**Starting a new feature:**
```
/ecc:plan "Add user authentication with OAuth"
                                              → planner creates implementation blueprint
/tdd                                          → tdd-guide enforces write-tests-first
/code-review                                  → code-reviewer checks your work
```

**Fixing a bug:**
```
/tdd                                          → tdd-guide: write a failing test that reproduces it
                                              → implement the fix, verify test passes
/code-review                                  → code-reviewer: catch regressions
```

**Preparing for production:**
```
/security-scan                                → security-reviewer: OWASP Top 10 audit
/e2e                                          → e2e-runner: critical user flow tests
/test-coverage                                → verify 80%+ coverage
```

## FAQ

<details>
<summary><b>How do I check which agents/commands are installed?</b></summary>

```bash
/plugin list ecc@ecc
```

This shows all available agents, commands, and skills from the plugin.
</details>

<details>
<summary><b>My hooks aren't working / I see "Duplicate hooks file" errors</b></summary>

This is the most common issue. **Do NOT add a `"hooks"` field to `.claude-plugin/plugin.json`.** Claude Code v2.1+ automatically loads `hooks/hooks.json` from installed plugins. Explicitly declaring it causes duplicate detection errors. See [#29](https://github.com/affaan-m/everything-claude-code/issues/29), [#52](https://github.com/affaan-m/everything-claude-code/issues/52), [#103](https://github.com/affaan-m/everything-claude-code/issues/103).
</details>

<details>
<summary><b>Can I use ECC with Claude Code on a custom API endpoint or model gateway?</b></summary>

Yes. ECC does not hardcode Anthropic-hosted transport settings. It runs locally through Claude Code's normal CLI/plugin surface, so it works with:

- Anthropic-hosted Claude Code
- Official Claude Code gateway setups using `ANTHROPIC_BASE_URL` and `ANTHROPIC_AUTH_TOKEN`
- Compatible custom endpoints that speak the Anthropic API Claude Code expects

Minimal example:

```bash
export ANTHROPIC_BASE_URL=https://your-gateway.example.com
export ANTHROPIC_AUTH_TOKEN=your-token
claude
```

If your gateway remaps model names, configure that in Claude Code rather than in ECC. ECC's hooks, skills, commands, and rules are model-provider agnostic once the `claude` CLI is already working.

Official references:
- [Claude Code LLM gateway docs](https://docs.anthropic.com/en/docs/claude-code/llm-gateway)
- [Claude Code model configuration docs](https://docs.anthropic.com/en/docs/claude-code/model-config)

</details>

<details>
<summary><b>My context window is shrinking / Claude is running out of context</b></summary>

Too many MCP servers eat your context. Each MCP tool description consumes tokens from your 200k window, potentially reducing it to ~70k.

**Fix:** Disable unused MCPs per project:
```json
// In your project's .claude/settings.json
{
  "disabledMcpServers": ["supabase", "railway", "vercel"]
}
```

Keep under 10 MCPs enabled and under 80 tools active.
</details>

<details>
<summary><b>Can I use only some components (e.g., just agents)?</b></summary>

Yes. Use Option 2 (manual installation) and copy only what you need:

```bash
# Just agents
cp everything-claude-code/agents/*.md ~/.claude/agents/

# Just rules
mkdir -p ~/.claude/rules/
cp -r everything-claude-code/rules/common ~/.claude/rules/
```

Each component is fully independent.
</details>

<details>
<summary><b>Does this work with Cursor / OpenCode / Codex / Antigravity?</b></summary>

Yes. ECC is cross-platform:
- **Cursor**: Pre-translated configs in `.cursor/`. See [Cursor IDE Support](#cursor-ide-support).
- **Gemini CLI**: Experimental project-local support via `.gemini/GEMINI.md` and shared installer plumbing.
- **OpenCode**: Full plugin support in `.opencode/`. See [OpenCode Support](#opencode-support).
- **Codex**: First-class support for both macOS app and CLI, with adapter drift guards and SessionStart fallback. See PR [#257](https://github.com/affaan-m/everything-claude-code/pull/257).
- **Antigravity**: Tightly integrated setup for workflows, skills, and flattened rules in `.agent/`. See [Antigravity Guide](docs/ANTIGRAVITY-GUIDE.md).
- **Non-native harnesses**: Manual fallback path for Grok and similar interfaces. See [Manual Adaptation Guide](docs/MANUAL-ADAPTATION-GUIDE.md).
- **Claude Code**: Native — this is the primary target.
</details>

<details>
<summary><b>How do I contribute a new skill or agent?</b></summary>

See [CONTRIBUTING.md](CONTRIBUTING.md). The short version:
1. Fork the repo
2. Create your skill in `skills/your-skill-name/SKILL.md` (with YAML frontmatter)
3. Or create an agent in `agents/your-agent.md`

---

## Cursor IDE Support

ECC provides **full Cursor IDE support** with hooks, rules, agents, skills, commands, and MCP configs adapted for Cursor's native format.

### Quick Start (Cursor)

```bash
# macOS/Linux
./install.sh --target cursor typescript
./install.sh --target cursor python golang swift php
```

```powershell
# Windows PowerShell
.\install.ps1 --target cursor typescript
.\install.ps1 --target cursor python golang swift php
```

### What's Included

| Component | Count | Details |
|-----------|-------|---------|
| Hook Events | 15 | sessionStart, beforeShellExecution, afterFileEdit, beforeMCPExecution, beforeSubmitPrompt, and 10 more |
| Hook Scripts | 16 | Thin Node.js scripts delegating to `scripts/hooks/` via shared adapter |
| Rules | 34 | 9 common (alwaysApply) + 25 language-specific (TypeScript, Python, Go, Swift, PHP) |
| Agents | Shared | Via AGENTS.md at root (read by Cursor natively) |
| Skills | Shared + Bundled | Via AGENTS.md at root and `.cursor/skills/` for translated additions |
| Commands | Shared | `.cursor/commands/` if installed |
| MCP Config | Shared | `.cursor/mcp.json` if installed |

### Hook Architecture (DRY Adapter Pattern)

Cursor has **more hook events than Claude Code** (20 vs 8). The `.cursor/hooks/adapter.js` module transforms Cursor's stdin JSON to Claude Code's format, allowing existing `scripts/hooks/*.js` to be reused without duplication.

```
Cursor stdin JSON → adapter.js → transforms → scripts/hooks/*.js
                                              (shared with Claude Code)
```

Key hooks:
- **beforeShellExecution** — Blocks dev servers outside tmux (exit 2), git push review
- **afterFileEdit** — Auto-format + TypeScript check + console.log warning
- **beforeSubmitPrompt** — Detects secrets (sk-, ghp_, AKIA patterns) in prompts
- **beforeTabFileRead** — Blocks Tab from reading .env, .key, .pem files (exit 2)
- **beforeMCPExecution / afterMCPExecution** — MCP audit logging

### Rules Format

Cursor rules use YAML frontmatter with `description`, `globs`, and `alwaysApply`:

```yaml
---
description: "TypeScript coding style extending common rules"
globs: ["**/*.ts", "**/*.tsx", "**/*.js", "**/*.jsx"]
alwaysApply: false
---
```

---

## Codex macOS App + CLI Support

ECC provides **first-class Codex support** for both the macOS app and CLI, with a reference configuration, Codex-specific AGENTS.md supplement, and shared skills.

### Quick Start (Codex App + CLI)

```bash
# Run Codex CLI in the repo — AGENTS.md and .codex/ are auto-detected
codex

# Automatic setup: sync ECC assets (AGENTS.md, skills, MCP servers) into ~/.codex
npm install && bash scripts/sync-ecc-to-codex.sh
# or: pnpm install && bash scripts/sync-ecc-to-codex.sh
# or: yarn install && bash scripts/sync-ecc-to-codex.sh
# or: bun install && bash scripts/sync-ecc-to-codex.sh

# Or manually: copy the reference config to your home directory
cp .codex/config.toml ~/.codex/config.toml
```

The sync script safely merges ECC MCP servers into your existing `~/.codex/config.toml` using an **add-only** strategy — it never removes or modifies your existing servers. Run with `--dry-run` to preview changes, or `--update-mcp` to force-refresh ECC servers to the latest recommended config.

For Context7, ECC uses the canonical Codex section name `[mcp_servers.context7]` while still launching the `@upstash/context7-mcp` package. If you already have a legacy `[mcp_servers.context7-mcp]` entry, `--update-mcp` migrates it to the canonical section name.

Codex macOS app:
- Open this repository as your workspace.
- The root `AGENTS.md` is auto-detected.
- `.codex/config.toml` and `.codex/agents/*.toml` work best when kept project-local.
- The reference `.codex/config.toml` intentionally does not pin `model` or `model_provider`, so Codex uses its own current default unless you override it.
- Optional: copy `.codex/config.toml` to `~/.codex/config.toml` for global defaults; keep the multi-agent role files project-local unless you also copy `.codex/agents/`.

### What's Included

### Key Limitation

Codex does **not yet provide Claude-style hook execution parity**. ECC enforcement there is instruction-based via `AGENTS.md`, optional `model_instructions_file` overrides, and sandbox/approval settings.

### Multi-Agent Support

Current Codex builds support stable multi-agent workflows.

- Enable `features.multi_agent = true` in `.codex/config.toml`
- Define roles under `[agents.<name>]`
- Point each role at a file under `.codex/agents/`
- Use `/agent` in the CLI to inspect or steer child agents

ECC ships three sample role configs:

| Role | Purpose |
|------|---------|
| `explorer` | Read-only codebase evidence gathering before edits |
| `reviewer` | Correctness, security, and missing-test review |
| `docs_researcher` | Documentation and API verification before release/docs changes |

---

## OpenCode Support

ECC provides **full OpenCode support** including plugins and hooks.

### Quick Start

```bash
# Install OpenCode
npm install -g opencode

# Run in the repository root
opencode
```

The configuration is automatically detected from `.opencode/opencode.json`.

### Feature Parity

| Feature | Claude Code | OpenCode | Status |
|---------|-------------|----------|--------|
| Agents | PASS: 47 agents | PASS: 12 agents | **Claude Code leads** |
| Commands | PASS: 79 commands | PASS: 31 commands | **Claude Code leads** |
| Skills | PASS: 181 skills | PASS: 37 skills | **Claude Code leads** |
| Hooks | PASS: 8 event types | PASS: 11 events | **OpenCode has more!** |
| Rules | PASS: 29 rules | PASS: 13 instructions | **Claude Code leads** |
| MCP Servers | PASS: 14 servers | PASS: Full | **Full parity** |
| Custom Tools | PASS: Via hooks | PASS: 6 native tools | **OpenCode is better** |

### Hook Support via Plugins

OpenCode's plugin system is MORE sophisticated than Claude Code with 20+ event types:

| Claude Code Hook | OpenCode Plugin Event |
|-----------------|----------------------|
| PreToolUse | `tool.execute.before` |
| PostToolUse | `tool.execute.after` |
| Stop | `session.idle` |
| SessionStart | `session.created` |
| SessionEnd | `session.deleted` |

**Additional OpenCode events**: `file.edited`, `file.watcher.updated`, `message.updated`, `lsp.client.diagnostics`, `tui.toast.show`, and more.

### Plugin Installation

**Option 1: Use directly**
```bash
cd everything-claude-code
opencode
```

**Option 2: Install as npm package**
```bash
npm install ecc-universal
```

Then add to your `opencode.json`:
```json
{
  "plugin": ["ecc-universal"]
}
```

That npm plugin entry enables ECC's published OpenCode plugin module (hooks/events and plugin tools).
It does **not** automatically add ECC's full command/agent/instruction catalog to your project config.

For the full ECC OpenCode setup, either:
- run OpenCode inside this repository, or
- copy the bundled `.opencode/` config assets into your project and wire the `instructions`, `agent`, and `command` entries in `opencode.json`

### Documentation

- **Migration Guide**: `.opencode/MIGRATION.md`
- **OpenCode Plugin README**: `.opencode/README.md`
- **Consolidated Rules**: `.opencode/instructions/INSTRUCTIONS.md`
- **LLM Documentation**: `llms.txt` (complete OpenCode docs for LLMs)

## Cross-Tool Feature Parity

ECC is the **first plugin to maximize every major AI coding tool**. Here's how each harness compares:

| Feature | Claude Code | Cursor IDE | Codex CLI | OpenCode |
|---------|------------|------------|-----------|----------|
| **Agents** | 47 | Shared (AGENTS.md) | Shared (AGENTS.md) | 12 |
| **Commands** | 79 | Shared | Instruction-based | 31 |
| **Skills** | 181 | Shared | 10 (native format) | 37 |
| **Hook Events** | 8 types | 15 types | None yet | 11 types |
| **Hook Scripts** | 20+ scripts | 16 scripts (DRY adapter) | N/A | Plugin hooks |
| **Rules** | 34 (common + lang) | 34 (YAML frontmatter) | Instruction-based | 13 instructions |
| **Custom Tools** | Via hooks | Via hooks | N/A | 6 native tools |
| **MCP Servers** | 14 | Shared (mcp.json) | 7 (auto-merged via TOML parser) | Full |
| **Config Format** | settings.json | hooks.json + rules/ | config.toml | opencode.json |
| **Context File** | CLAUDE.md + AGENTS.md | AGENTS.md | AGENTS.md | AGENTS.md |
| **Secret Detection** | Hook-based | beforeSubmitPrompt hook | Sandbox-based | Hook-based |
| **Auto-Format** | PostToolUse hook | afterFileEdit hook | N/A | file.edited hook |
| **Version** | Plugin | Plugin | Reference config | 1.10.0 |

**Key architectural decisions:**
- **AGENTS.md** at root is the universal cross-tool file (read by all 4 tools)
- **DRY adapter pattern** lets Cursor reuse Claude Code's hook scripts without duplication
- **Skills format** (SKILL.md with YAML frontmatter) works across Claude Code, Codex, and OpenCode
- Codex's lack of hooks is compensated by `AGENTS.md`, optional `model_instructions_file` overrides, and sandbox permissions

## Background

I've been using Claude Code since the experimental rollout. Won the Anthropic x Forum Ventures hackathon in Sep 2025 with [@DRodriguezFX](https://x.com/DRodriguezFX) — built [zenith.chat](https://zenith.chat) entirely using Claude Code.

These configs are battle-tested across multiple production applications.

## Token Optimization

Claude Code usage can be expensive if you don't manage token consumption. These settings significantly reduce costs without sacrificing quality.

### Recommended Settings

Add to `~/.claude/settings.json`:

```json
{
  "model": "sonnet",
  "env": {
    "MAX_THINKING_TOKENS": "10000",
    "CLAUDE_AUTOCOMPACT_PCT_OVERRIDE": "50"
  }
}
```

| Setting | Default | Recommended | Impact |
|---------|---------|-------------|--------|
| `model` | opus | **sonnet** | ~60% cost reduction; handles 80%+ of coding tasks |
| `MAX_THINKING_TOKENS` | 31,999 | **10,000** | ~70% reduction in hidden thinking cost per request |
| `CLAUDE_AUTOCOMPACT_PCT_OVERRIDE` | 95 | **50** | Compacts earlier — better quality in long sessions |

Switch to Opus only when you need deep architectural reasoning:
```
/model opus
```

### Daily Workflow Commands

| Command | When to Use |
|---------|-------------|
| `/model sonnet` | Default for most tasks |
| `/model opus` | Complex architecture, debugging, deep reasoning |
| `/clear` | Between unrelated tasks (free, instant reset) |
| `/compact` | At logical task breakpoints (research done, milestone complete) |
| `/cost` | Monitor token spending during session |

### Strategic Compaction

The `strategic-compact` skill (included in this plugin) suggests `/compact` at logical breakpoints instead of relying on auto-compaction at 95% context. See `skills/strategic-compact/SKILL.md` for the full decision guide.

**When to compact:**
- After research/exploration, before implementation
- After completing a milestone, before starting the next
- After debugging, before continuing feature work
- After a failed approach, before trying a new one

**When NOT to compact:**
- Mid-implementation (you'll lose variable names, file paths, partial state)

### Context Window Management

**Critical:** Don't enable all MCPs at once. Each MCP tool description consumes tokens from your 200k window, potentially reducing it to ~70k.

- Keep under 10 MCPs enabled per project
- Keep under 80 tools active
- Use `disabledMcpServers` in project config to disable unused ones

### Agent Teams Cost Warning

Agent Teams spawns multiple context windows. Each teammate consumes tokens independently. Only use for tasks where parallelism provides clear value (multi-module work, parallel reviews). For simple sequential tasks, subagents are more token-efficient.

---

## WARNING: Important Notes

### Token Optimization

Hitting daily limits? See the **[Token Optimization Guide](docs/token-optimization.md)** for recommended settings and workflow tips.

Quick wins:

```json
// ~/.claude/settings.json
{
  "model": "sonnet",
  "env": {
    "MAX_THINKING_TOKENS": "10000",
    "CLAUDE_AUTOCOMPACT_PCT_OVERRIDE": "50",
    "CLAUDE_CODE_SUBAGENT_MODEL": "haiku"
  }
}
```

Use `/clear` between unrelated tasks, `/compact` at logical breakpoints, and `/cost` to monitor spending.

### Customization

These configs work for my workflow. You should:
1. Start with what resonates
2. Modify for your stack
3. Remove what you don't use
4. Add your own patterns
