Everything Claude Code (ECC) — Agent Harness Performance System Skill by ara.so — Daily 2026 Skills collection. Everything Claude Code (ECC) is a production-ready performance optimization system for AI agent harnesses. It provides specialized subagents, reusable skills, custom slash commands, memory-persisting hooks, security scanning, and language-specific rules — all evolved from 10+ months of daily real-world use. Works across Claude Code, Cursor, Codex, OpenCode, and Antigravity. Installation Option 1: Plugin Marketplace (Recommended)

Inside Claude Code, run:

/plugin marketplace add affaan-m/everything-claude-code /plugin install everything-claude-code@everything-claude-code Option 2: Manual Clone git clone https://github.com/affaan-m/everything-claude-code.git cd everything-claude-code

Install rules for your language stack

./install.sh typescript

Multiple languages:

./install.sh typescript python golang swift

Target a specific IDE:

./install.sh --target cursor typescript Install Rules (Always Required) Claude Code plugins cannot auto-distribute rules — install them manually via ./install.sh or copy from rules/ into your project's .claude/rules/ directory.

Planning & architecture

/everything-claude-code:plan "Add OAuth2 login flow" /everything-claude-code:architect "Design a multi-tenant SaaS system"

PM2 orchestration

Package manager setup

/everything-claude-code:setup-pm With manual install, drop the everything-claude-code: prefix: /plan , /sessions , etc. Hook Runtime Controls ECC hooks fire at agent lifecycle events. Control strictness at runtime without editing files:

Set hook strictness profile

export ECC_HOOK_PROFILE = minimal

Least intrusive

export ECC_HOOK_PROFILE = standard

Default

export ECC_HOOK_PROFILE = strict

Maximum enforcement

Disable specific hooks by ID (comma-separated)

export ECC_DISABLED_HOOKS = "pre:bash:tmux-reminder,post:edit:typecheck" Hook events covered: SessionStart , Stop , PostEdit , PreBash , PostBash , and more. Package Manager Detection ECC auto-detects your package manager with this priority chain: CLAUDE_PACKAGE_MANAGER environment variable .claude/package-manager.json (project-level) package.json → packageManager field Lock file detection ( package-lock.json , yarn.lock , pnpm-lock.yaml , bun.lockb ) ~/.claude/package-manager.json (global) First available manager as fallback

Set via environment

export CLAUDE_PACKAGE_MANAGER = pnpm

Set globally

node scripts/setup-package-manager.js --global pnpm

Set per-project

node scripts/setup-package-manager.js --project bun

Detect current setting

node scripts/setup-package-manager.js --detect Skills System Skills are markdown modules the agent loads to gain domain expertise. Install individually or in bulk. Using a Skill

Reference a skill explicitly in your prompt

"Use the search-first skill to find the right caching approach before implementing"

Or trigger via slash command

/everything-claude-code:research "content hashing strategies for API responses" Notable Built-in Skills Skill Purpose search-first Research before coding — avoids hallucinated APIs cost-aware-llm-pipeline Optimizes token spend across model calls content-hash-cache-pattern Cache invalidation via content hashing skill-stocktake Audits which skills are loaded and active frontend-slides Zero-dependency HTML presentation builder configure-ecc Guided interactive ECC setup wizard swift-actor-persistence Swift concurrency + persistence patterns regex-vs-llm-structured-text Decides when to use regex vs LLM parsing Writing a Custom Skill Create skills/my-skill.md :

Rules

Rule one

Rule two Instincts System (Continuous Learning) Instincts are session-extracted patterns saved for reuse. They carry confidence scores and evolve over time. Export an Instinct /everything-claude-code:instinct-import Instinct File Format

name : prefer - zod - for - validation confidence : 0.92 extracted_from : session - 2026-02-14

Action Always use Zod for runtime schema validation in TypeScript projects.

Evidence Caught 3 runtime type errors that TypeScript alone missed during session.

Examples ```typescript import { z } from 'zod' const UserSchema = z.object({ id: z.string().uuid(), email: z.string().email(), role: z.enum(['admin', 'user']) }) type User = z.infer < typeof UserSchema

``` Rules Architecture Rules enforce coding standards per language. Install only what your stack needs.

TypeScript + Python

./install.sh typescript python

In your prompt, reference an agent explicitly

"Delegate architecture decisions to the architect agent" "Use the planner agent to break this feature into tasks" Available agents include: planner , architect , researcher , verifier , security-auditor , and more. Each lives in agents/.md with its own system prompt, tools list, and constraints. AgentShield Security Scanning Run security scans directly from Claude Code: /everything-claude-code:security-scan This invokes the AgentShield scanner (1282 tests, 102 rules) against your codebase and surfaces: Hardcoded secrets Injection vulnerabilities Insecure dependencies Agent prompt injection patterns Memory Persistence Hooks ECC hooks automatically save and restore session context: // hooks/session-start.js — loads prior context on new session const fs = require ( 'fs' ) const path = require ( 'path' ) const memoryPath = path . join ( process . env . HOME , '.claude' , 'session-memory.json' ) if ( fs . existsSync ( memoryPath ) ) { const memory = JSON . parse ( fs . readFileSync ( memoryPath , 'utf8' ) ) console . log ( 'Restored session context:' , memory . summary ) } // hooks/stop.js — saves session summary on exit const summary = { timestamp : new Date ( ) . toISOString ( ) , summary : process . env . ECC_SESSION_SUMMARY || '' , skills_used : ( process . env . ECC_SKILLS_USED || '' ) . split ( ',' ) } fs . writeFileSync ( memoryPath , JSON . stringify ( summary , null , 2 ) ) Cross-Platform Support Platform Support Claude Code Full (agents, commands, skills, hooks, rules) Cursor Full (via --target cursor installer flag) OpenCode Full (plugin system, 20+ hook event types, 3 native tools) Codex CLI Full ( codex.md generated via /codex-setup ) Codex App Full ( AGENTS.md -based) Antigravity Full (via --target antigravity installer flag) Common Patterns Research-First Development "Before implementing the payment webhook handler, use the search-first skill to verify current Stripe webhook verification best practices." Token Optimization

Route to cheaper model for simple tasks

/everything-claude-code:model-route "Write a unit test for this pure function"

Use background processes for long analysis

/everything-claude-code:harness-audit Parallelization with Git Worktrees

Create isolated worktrees for parallel agent tasks

git worktree add .. /feature-auth -b feature/auth git worktree add .. /feature-payments -b feature/payments

Each Claude Code session operates in its own worktree

Merge when both complete

Verification Loop /everything-claude-code:loop-start

Begin tracked loop

... agent does work ...

/everything-claude-code:loop-status

Check progress

/everything-claude-code:quality-gate

Enforce pass criteria before merge

Troubleshooting Plugin commands not found after install /plugin list everything-claude-code@everything-claude-code

If empty, re-run: /plugin install everything-claude-code@everything-claude-code

Rules not applied

Rules require manual install — plugin system cannot distribute them

cd everything-claude-code && ./install.sh typescript

Verify:

ls ~/.claude/rules/

or .claude/rules/ in project root

Hooks not firing

Check profile setting

echo $ECC_HOOK_PROFILE

Check disabled list

echo $ECC_DISABLED_HOOKS

Reset to defaults

unset ECC_HOOK_PROFILE unset ECC_DISABLED_HOOKS Instinct import drops content Ensure you're on v1.4.1+. Earlier versions had a bug where parse_instinct_file() silently dropped Action/Evidence/Examples sections. Pull latest and re-run. Wrong package manager used node scripts/setup-package-manager.js --detect export CLAUDE_PACKAGE_MANAGER = pnpm
