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 ``` ```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 # 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 # Try a command (plugin install uses namespaced form) /everything-claude-code:plan "Add user authentication" # Manual install (Option 2) uses the shorter form: # /plan "Add user authentication" # Check available commands /plugin list everything-claude-code@everything-claude-code ``` ✨ **That's it!** You now have access to 29 agents, 132 skills, and 60 commands. ### Multi-model commands require additional setup > ⚠️ `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" ``` --- ## 📦 What's Inside This repo is a **Claude Code plugin** - install it directly or copy components manually. ``` everything-claude-code/ |-- .claude-plugin/ #

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 # 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 > ⚠️ **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 affaan-m/everything-claude-code # Install the plugin /plugin install everything-claude-code@everything-claude-code ``` Or add directly to your `~/.claude/settings.json`: ```json { "extraKnownMarketplaces": { "everything-claude-code": { "source": { "source": "github", "repo": "affaan-m/everything-claude-code" } } }, "enabledPlugins": { "everything-claude-code@everything-claude-code": 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 commands cp everything-claude-code/commands/*.md ~/.claude/commands/ # Copy skills (core vs niche) # 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/$s ~/.claude/skills/ # done ``` #### Add hooks to settings.json Copy the hooks from `hooks/hooks.json` to your `~/.claude/settings.json`. #### Configure MCPs Copy desired MCP servers from `mcp-configs/mcp-servers.json` to your `~/.claude.json`. **Important:** Replace `YOUR_*_HERE` placeholders with your actual API keys. --- ## 🎯 Key Concepts ### Agents Subagents handle delegated tasks with limited scope. Example: ```markdown --- name: code-reviewer description: Reviews code for quality, security, and maintainability tools: ["Read", "Grep", "Glob", "Bash"] model: opus --- You are a senior code reviewer... ``` ### Skills Skills are workflow definitions invoked by commands or agents: ```markdown # TDD Workflow 1. Define interfaces first 2. Write failing tests (RED) 3. Implement minimal code (GREEN) 4. Refactor (IMPROVE) 5. Verify 80%+ coverage ``` ### Hooks Hooks fire on tool events. Example - warn about console.log: ```json { "matcher": "tool == \"Edit\" && tool_input.file_path matches \"\\\\.(ts|tsx|js|jsx)$\"", "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?

How do I check which agents/commands are installed? ```bash /plugin list everything-claude-code@everything-claude-code ``` This shows all available agents, commands, and skills from the plugin.
My hooks aren't working / I see "Duplicate hooks file" errors 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).
Can I use ECC with Claude Code on a custom API endpoint or model gateway? 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)
My context window is shrinking / Claude is running out of context 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.
Can I use only some components (e.g., just agents)? 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.
Does this work with Cursor / OpenCode / Codex / Antigravity? Yes. ECC is cross-platform: - **Cursor**: Pre-translated configs in `.cursor/`. See [Cursor IDE Support](#cursor-ide-support). - **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). - **Claude Code**: Native — this is the primary target.

--- ## 🧪 Running Tests The plugin includes a comprehensive test suite: ```bash # Run all tests node tests/run-all.js # Run individual test files node tests/lib/utils.test.js node tests/lib/package-manager.test.js node tests/hooks/hooks.test.js ``` --- ## 🤝 Contributing **Contributions are welcome and encouraged.** This repo is meant to be a community resource. If you have: - Useful agents or skills - Clever hooks - Better MCP configurations - Improved rules Please contribute! See [CONTRIBUTING.md](CONTRIBUTING.md) for guidelines. ### Ideas for Contributions - Language-specific skills (Rust, C#, Kotlin, Java) — Go, Python, Perl, Swift, and TypeScript already included - Framework-specific configs (Rails, FastAPI, NestJS) — Django, Spring Boot, Laravel already included - DevOps agents (Kubernetes, Terraform, AWS, Docker) - Testing strategies (different frameworks, visual regression) - Domain-specific knowledge (ML, data engineering, mobile) --- ## 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 | Component | Count | Details | |-----------|-------|---------| | Config | 1 | `.codex/config.toml` — top-level approvals/sandbox/web_search, MCP servers, notifications, profiles | | AGENTS.md | 2 | Root (universal) + `.codex/AGENTS.md` (Codex-specific supplement) | | Skills | 16 | `.agents/skills/` — SKILL.md + agents/openai.yaml per skill | | MCP Servers | 6 | Supabase, Playwright, Context7, GitHub, Memory, Sequential Thinking (auto-merged via add-only sync) | | Profiles | 2 | `strict` (read-only sandbox) and `yolo` (full auto-approve) | | Agent Roles | 3 | `.codex/agents/` — explorer, reviewer, docs-researcher | ### Skills Skills at `.agents/skills/` are auto-loaded by Codex: | Skill | Description | |-------|-------------| | tdd-workflow | Test-driven development with 80%+ coverage | | security-review | Comprehensive security checklist | | coding-standards | Universal coding standards | | frontend-patterns | React/Next.js patterns | | frontend-slides | HTML presentations, PPTX conversion, visual style exploration | | article-writing | Long-form writing from notes and voice references | | content-engine | Platform-native social content and repurposing | | market-research | Source-attributed market and competitor research | | investor-materials | Decks, memos, models, and one-pagers | | investor-outreach | Personalized outreach, follow-ups, and intro blurbs | | backend-patterns | API design, database, caching | | e2e-testing | Playwright E2E tests | | eval-harness | Eval-driven development | | strategic-compact | Context management | | api-design | REST API design patterns | | verification-loop | Build, test, lint, typecheck, security | ### 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 experimental multi-agent workflows. - Enable `features.multi_agent = true` in `.codex/config.toml` - Define roles under `[agents.]` - 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 | ✅ 29 agents | ✅ 12 agents | **Claude Code leads** | | Commands | ✅ 60 commands | ✅ 31 commands | **Claude Code leads** | | Skills | ✅ 132 skills | ✅ 37 skills | **Claude Code leads** | | Hooks | ✅ 8 event types | ✅ 11 events | **OpenCode has more!** | | Rules | ✅ 29 rules | ✅ 13 instructions | **Claude Code leads** | | MCP Servers | ✅ 14 servers | ✅ Full | **Full parity** | | Custom Tools | ✅ Via hooks | ✅ 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. ### Available Commands (31+) | Command | Description | |---------|-------------| | `/plan` | Create implementation plan | | `/tdd` | Enforce TDD workflow | | `/code-review` | Review code changes | | `/build-fix` | Fix build errors | | `/e2e` | Generate E2E tests | | `/refactor-clean` | Remove dead code | | `/orchestrate` | Multi-agent workflow | | `/learn` | Extract patterns from session | | `/checkpoint` | Save verification state | | `/verify` | Run verification loop | | `/eval` | Evaluate against criteria | | `/update-docs` | Update documentation | | `/update-codemaps` | Update codemaps | | `/test-coverage` | Analyze coverage | | `/go-review` | Go code review | | `/go-test` | Go TDD workflow | | `/go-build` | Fix Go build errors | | `/python-review` | Python code review (PEP 8, type hints, security) | | `/multi-plan` | Multi-model collaborative planning | | `/multi-execute` | Multi-model collaborative execution | | `/multi-backend` | Backend-focused multi-model workflow | | `/multi-frontend` | Frontend-focused multi-model workflow | | `/multi-workflow` | Full multi-model development workflow | | `/pm2` | Auto-generate PM2 service commands | | `/sessions` | Manage session history | | `/skill-create` | Generate skills from git | | `/instinct-status` | View learned instincts | | `/instinct-import` | Import instincts | | `/instinct-export` | Export instincts | | `/evolve` | Cluster instincts into skills | | `/promote` | Promote project instincts to global scope | | `/projects` | List known projects and instinct stats | | `/prune` | Delete expired pending instincts (30d TTL) | | `/learn-eval` | Extract and evaluate patterns before saving | | `/setup-pm` | Configure package manager | | `/harness-audit` | Audit harness reliability, eval readiness, and risk posture | | `/loop-start` | Start controlled agentic loop execution pattern | | `/loop-status` | Inspect active loop status and checkpoints | | `/quality-gate` | Run quality gate checks for paths or entire repo | | `/model-route` | Route tasks to models by complexity and budget | ### 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** | 21 | Shared (AGENTS.md) | Shared (AGENTS.md) | 12 | | **Commands** | 52 | Shared | Instruction-based | 31 | | **Skills** | 102 | 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 | 1.9.0 | **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. --- ## ⚠️ 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 --- ## 💜 Sponsors This project is free and open source.
