**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)

- **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](https://github.com/marketplace/ecc-tools) w
