Guys! I just stumbled upon an open-source project that really made me pause. It’s an open-source project by cogsec expert @affaan called Everything Claude Code, or ECC for short. GitHub 205K Project URL: https://github.com/affaan-m/ECC At first, I thought it was just another collection of prompts repackaged under a different name. But after clicking in, I realized it’s not. It basically prepares all the annoying stuff you usually deal with when setting up an AI coding workflow, ahead of time. Finding agents, configuring skills, writing commands, building workflows, doing security checks, integrating Claude Code / Codex / Cursor… Normally, doing all this yourself can easily take hours to days. But ECC has already bundled: 63 agents, 249 skills, 79 commands, AgentShield with 1282 built-in security tests. Supports Claude Code, Codex, Cursor, OpenCode, Gemini. Covers planning, code review, bug fixing, TDD, documentation, research, content workflows. What struck me most: It doesn’t feel like just giving you a few prompts. It feels like, before you even start a project, it lays out a complete AI coding toolbox in front of you. Of course, this doesn’t mean your project will automatically succeed just by installing it. But if you’ve ever spent a lot of time building your own AI coding workflow, searching for the right agents, tweaking commands, configuring environments, you’ll understand why this repo is worth saving. Honestly, this is one of the more interesting AI coding repos I’ve seen in recent weeks.

Built from real-world multi-harness engineering workflows. 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 Codex, Claude Code, Cursor, OpenCode, Gemini, Zed, GitHub Copilot, and other AI agent harnesses. ECC v2.0.0-rc.1 adds the public Hermes operator story on top of that reusable layer: start with the Hermes setup guide, then review the rc.1 release notes and cross-harness architecture. — ECC Pro Private repos · GitHub App · $19/seat/mo Sponsor Fund the OSS · From $5/mo Community Discussions · Q&A · Show & Tell GitHub App Install · PR audits · Free tier OSS stays free.

Shorthand GuideSetup, foundations, philosophy. Read this first. Longform GuideToken optimization, memory persistence, evals, parallelization. Security GuideAttack vectors, sandboxing, sanitization, CVEs, AgentShield. | Topic | What You’ll Learn | |—––|—————––| | Token Optimization | Model selection, system prompt slimming, background processes | | Memory Persistence | Hooks that save/load context across sessions automatically | | Continuous Learning | Auto-extract patterns from sessions into reusable skills | | Verification Loops | Checkpoint vs continuous evals, grader types, pass@k metrics | | Parallelization | Git worktrees, cascade method, when to scale instances | | Subagent Orchestration | The context problem, iterative retrieval pattern | — ## What’s New ### v2.0.0-rc.1 — 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: 63 agents, 249 skills, and 79 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. - Itô prediction-market skill pack — ito-market-intelligence, ito-basket-compare, ito-trade-planner, ito-data-atlas-agent, prediction-market-oracle-research, and prediction-market-risk-review add public, non-advisory market/basket workflows while keeping live Itô API access gated and separate from ECC Tools billing. - Optimization skill pack — parallel-execution-optimizer, benchmark-optimization-loop, data-throughput-accelerator, latency-critical-systems, and recursive-decision-ledger turn repeated speed/recursion prompts into bounded benchmark, throughput, and decision-ledger workflows. - 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. - Operator status snapshots — ecc status --markdown --write status.md turns the local state store into a portable handoff covering readiness, active sessions, skill-run health, install health, pending governance events, and linked work items from Linear/GitHub/handoffs. Use ecc work-items upsert ... for manual entries, ecc work-items sync-github --repo owner/repo for PR/issue queue state, and ecc status --exit-code to fail automation when readiness needs attention. - 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.

The most common broken setup is: /plugin install first, then install.sh --profile full or npx ecc-install --profile full afterward. If you already layered multiple installs and things look duplicated, skip straight to Reset / Uninstall ECC. ### Low-context / no-hooks path If hooks feel too global or you only want ECC’s rules, agents, commands, and core workflow skills, skip the plugin and use the minimal manual profile: bash ./install.sh --profile minimal --target claude powershell .\install.ps1 --profile minimal --target claude # or npx ecc-install --profile minimal --target claude This profile intentionally excludes hooks-runtime. If you want the normal core profile but need hooks off, use: bash ./install.sh --profile core --without baseline:hooks --target claude Add hooks later only if you want runtime enforcement: bash ./install.sh --target claude --modules hooks-runtime ### Find the right components first If you are not sure which ECC profile or component to install, ask the packaged advisor from any project: bash npx ecc consult "security reviews" --target claude It returns matching components, related profiles, and preview/install commands. Use the preview command before installing if you want to inspect the exact file plan. For production ML/MLOps workflows, keep the install opt-in and component-scoped: bash npx ecc consult "mlops training model deployment" --target claude npx ecc install --profile minimal --target claude --with capability:machine-learning ### Step 1: Install the Plugin (Recommended) > 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/ECC # Install plugin /plugin install ecc@ecc ### Naming + Migration Note ECC now has three public identifiers, and they are not interchangeable: - GitHub source repo: affaan-m/ECC - Claude marketplace/plugin identifier: ecc@ecc - npm package: ecc-universal This is intentional. Anthropic marketplace/plugin installs are keyed by a canonical plugin identifier, so ECC uses ecc@ecc to keep tool names and slash-command namespaces short enough for strict Desktop/API validators. Older posts may still show the former long marketplace identifier; treat that as a legacy alias only. Separately, the npm package stayed on ecc-universal, so npm installs and marketplace installs intentionally use different names. ### Step 2: Install Rules Only If You Ne
