# ECC

Your agent can write code, but ECC gives it a coordinated engineering system and toolbox: it plans before it builds, verifies changes with tests, reviews its own work from a fresh context, remembers what matters, and turns repeated wins into reusable skills and workflows.

```text
plan -> test -> implement -> review -> verify -> remember -> improve
```

Instead of rebuilding that process in every prompt, you install it once and make it part of how your agent works.

> Optimize the context window. Persist everything else.

ECC is MIT-licensed open source. It works best with Claude Code today, has a supported Codex sync path, and provides capability-limited adapters for Cursor, OpenCode, Gemini, Zed, GitHub Copilot, Antigravity, Qwen, and other harnesses. See the [support status matrix](#platform-support) before assuming feature parity.

Access to 68 agents, 292 skills, and 94 legacy command shims, plus hooks, rules, memory, continuous learning, and AgentShield security scanning. The agents are specialized for planning, review, build repair, security, architecture, and domain work.

## Install ECC

> [!IMPORTANT]
> ECC 2.2 includes guided package setup for Claude Code, Codex, and Kimi Code.
> The universal package requires Node.js 18 or newer. Claude plugin setup also
> requires Git and Claude Code 2.1 or newer on `PATH`.

### Recommended: universal guided setup

For Claude Code plugin setup, updates, scope changes, and hook-profile changes:

```bash
npx ecc-universal@2.2.1 setup
```

If npm reports a version or cache error, confirm the registry version before retrying:

```bash
npm view ecc-universal version
```

ECC 2.2 supports the same guided setup through modern package runners:

| Package runner | Guided setup command |
|---|---|
| npm / npx | `npx ecc-universal@2.2.1 setup` |
| pnpm | `pnpm dlx ecc-universal@2.2.1 setup` |
| Yarn 2+ | `yarn dlx ecc-universal@2.2.1 setup` |
| Bun | `bunx ecc-universal@2.2.1 setup` |

The examples select [the published ECC 2.2.1 release](https://www.npmjs.com/package/ecc-universal/v/2.2.1), matching this repository's release version. A version pin is not a security audit or an integrity check. Review the release source and registry integrity before running package code; use a reviewed checkout for unreleased changes.

Yarn Classic 1 does not provide `yarn dlx`; use `npx`, install the package globally, or upgrade Yarn for a temporary one-shot run.

The wizard inventories the official marketplace and every native Claude install scope before making changes, then installs, updates, or safely moves `ecc@ecc` to the scope you choose. Rerun the same command whenever you want to update ECC, change scope, or change its hook profile. This setup wizard currently configures the Claude Code plugin; use the multi-harness wizard below for Codex or Kimi Code.

To configure more than one coding agent in one reviewed flow, use the multi-harness wizard:

```bash
npx ecc-universal@2.2.1 install --guided
```

It lets you select any combination of Claude Code, Codex, and Kimi Code, shows each install channel and destination, preflights every selection before the first write, and asks for one final confirmation.

| Harness | Guided install behavior |
|---|---|
| Claude Code | Native `ecc@ecc` plugin with one `user`, `project`, or `local` scope and an ECC hook profile |
| Codex | Native Codex marketplace/plugin lifecycle; hook review and trust remain Codex-owned |
| Kimi Code | Managed project files under `./.kimi-code`; ECC hooks, model/provider settings, and authentication are not configured |

For automation, make every provider-specific choice explicit:

```bash
npx ecc-universal@2.2.1 install --guided \
  --harness claude --harness codex --harness kimi \
  --claude-scope local --claude-hooks standard \
  --profile core --yes
```

Verify the native guided Codex path and managed Kimi path without writing first:

```bash
npx ecc-universal@2.2.1 install --guided --harness codex --dry-run
npx ecc-universal@2.2.1 install --profile core --target kimi --dry-run
```

Additional package-name commands are also available through the 2.2 alias:

```bash
npx ecc-universal@2.2.1 consult "security reviews" --target claude
npx ecc-universal@2.2.1 install --profile minimal --target claude --with capability:machine-learning
npx ecc-universal@2.2.1 doctor --target kimi
```

Do not use `npx ecc-install --profile minimal --target claude`: `ecc-install` is a binary name inside `ecc-universal`, not a separately published npm package.

ECC also ships advanced managed adapters for `cursor`, `antigravity`, `gemini`, `opencode`, `codebuddy`, `joycode`, `qwen`, `zed`, `hermes`, and `openclaw`. Those targets still use their documented `ecc install --target ...` paths until each adapter has passed the guided collision, update, repair, and uninstall lifecycle matrix. Neither wizard silently installs into every detected harness.

### Pick one path only (per harness)

You can use ECC with Claude Code, Codex, and other harnesses at the same time. Choose one install method for each harness:

- **Recommended default:** run the guided Claude plugin setup above
- **Also supported for Claude Code:** use the [native plugin commands](#claude-code-details)
- **Available in release 2.2:** guided package setup for Claude Code, Codex, and Kimi Code
- **Works:** Claude Code plugin + Codex native plugin
- **Works:** Claude Code plugin + the legacy Codex sync flow
- **Avoid:** Claude Code plugin + full Claude manual install
- **Avoid:** Codex sync + Codex marketplace plugin

**Do not stack install methods.** Installing ECC twice into the same harness can duplicate skills, commands, hooks, or configuration; installing it once into multiple harnesses does not.

If you already layered multiple installs and things look duplicated, skip straight to [Reset / Uninstall ECC](#reset--uninstall-ecc).

**Install trouble?** Open the short [install or runtime problem form](https://github.com/affaan-m/ECC/issues/new?template=install-problem.yml), or run `ecc feedback`. ECC never uploads diagnostics automatically.

### Claude Code details

Alternatively, run Claude Code's native plugin commands inside Claude Code:

```text
/plugin marketplace add https://github.com/affaan-m/ECC
/plugin install ecc@ecc
```

The native path installs ECC's skills, agents, commands, and plugin-managed hooks. If you choose it, stop there. Do not also run a full manual install into Claude Code.

Claude Code owns these built-in commands, including their errors when a marketplace, plugin, or conflicting scope already exists. ECC cannot intercept that parser. If either native command reports an existing install or scope conflict, use the 2.2 guided setup or resolve the conflicting Claude plugin scope before retrying; do not layer a manual install on top.

After ECC is installed, `/ecc:configure-ecc` is the namespaced in-Claude reconfiguration skill. It delegates to the same safe setup flow, but it is available only after the plugin is installed and cannot replace Claude Code's built-in `/plugin` command during a first install.

Claude Code plugins cannot distribute `rules`, so add only the rule packs you actually want:

```bash
git clone https://github.com/affaan-m/ECC.git
cd ECC
mkdir -p ~/.claude/rules/ecc
cp -R rules/common ~/.claude/rules/ecc/
cp -R rules/typescript ~/.claude/rules/ecc/  # replace with your stack
```

Start with `rules/common` plus one language or framework pack you actually use. If you install the plugin, do not run `./install.sh --profile full` afterward.

<details>
<summary><strong>Prefer settings.json? Add the marketplace declaratively</strong></summary>

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

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

This gives you the same result as the two `/plugin` commands above.
</details>

<details>
<summary><strong>Naming + migration note (ecc@ecc, affaan-m/ECC, ecc-universal)</strong></summary>

ECC 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.

npm releases are cut per version tag, not per commit, so `ecc-universal` tracks releases (2.1, 2.2, ...) rather than every push to `main`. Install from git if you want the bleeding edge.

If your local Claude setup was wiped or reset, that does not mean you need to repurchase anything. Start with `node scripts/ecc.js list-installed`, then run `node scripts/ecc.js doctor` and `node scripts/ecc.js repair` before reinstalling. That usually restores ECC-managed files without rebuilding your setup.
</details>

### Codex App and CLI

Current Codex releases can install ECC as a native repo-marketplace plugin. The marketplace entry uses the repository root so Codex's cache receives the manifest together with all referenced skills, MCP configuration, hook runtime, scripts, and assets:

```bash
codex plugin marketplace add affaan-m/ECC
codex plugin add ecc@ecc
codex plugin list --json
node scripts/codex/check-plugin-cache.js
```

Both add commands are idempotent. To refresh later, run `codex plugin marketplace upgrade ecc` followed by `codex plugin add ecc@ecc`. Codex stores one enabled plugin state in the active `CODEX_HOME`; it does not offer Claude's `user`, `project`, and `local` scopes. Its native hooks require an explicit trust decision and do not use Claude's four ECC hook profiles. Inside Codex, invoke `$configure-ecc` for the guided provider-aware flow.

The older `scripts/sync-ecc-to-codex.sh` path is a deprecated compatibility option for users who intentionally need copied and merged configuration in `~/.codex`; it is not required for the native plugin. New sync runs write an ownership manifest so cleanup can preserve modified user files. Run Codex once first so `~/.codex/config.toml` exists, then:

```bash
git clone https://github.com/affaan-m/ECC.git
cd ECC
npm install
bash scripts/sync-ecc-to-codex.sh
```

To inspect or remove that legacy layer without touching Codex conversations or native plugin caches:

```bash
node scripts/ecc.js uninstall --legacy-codex-sync --dry-run
node scripts/ecc.js uninstall --legacy-codex-sync
```

Pre-manifest installations are handled conservatively: ECC removes its marked `AGENTS.md` block but preserves copied files it cannot prove it owns and reports them for review.

You can also open the ECC repository directly in Codex for a project-local setup. Codex reads the root `AGENTS.md` and the trusted project configuration in `.codex/` without a global sync. Do not add the native marketplace plugin on top of the sync flow.

For repo navigation, surface ownership, and PR diff packet guidance, read the [Codex ECC Navigation Map](docs/CODEX-NAVIGATION-GUIDE.md). See the [.codex plugin notes](.codex-plugin/README.md) for native lifecycle details.

### Other agents and editors

<details>
<summary><strong>Cursor, OpenCode, Gemini, Zed, Antigravity, Qwen, Hermes, OpenClaw, Kimi, CodeBuddy, JoyCode, Copilot</strong></summary>

Clone ECC once, then choose the target that matches your harness:

```bash
git clone https://github.com/affaan-m/ECC.git
cd ECC
```

| Harness | Install or setup | Notes |
|---|---|---|
| Cursor | `./install.sh --profile minimal --target cursor` | Project-local `.cursor/` adapter |
| OpenCode | `npm install && npm run build:opencode && ./install.sh --profile full --target opencode --enable-hooks` | Builds the plugin payload before the full install |
| Gemini CLI | `./install.sh --profile minimal --target gemini` | Project-local `.gemini/` config |
| Zed | `./install.sh --profile minimal --target zed` | Project-local `.zed/` adapter |
| Antigravity | `./install.sh --profile minimal --target antigravity` | See the [Antigravity guide](docs/ANTIGRAVITY-GUIDE.md) |
| Qwen CLI | `./install.sh --profile minimal --target qwen` | See the [Qwen guide](docs/QWEN-GUIDE.md) |
| Hermes | `./install.sh --profile minimal --target hermes` | See the [Hermes setup guide](docs/HERMES-SETUP.md) |
| OpenClaw | `./install.sh --profile minimal --target openclaw` | Managed home-directory install |
| Kimi Code CLI | `./install.sh --profile minimal --target kimi` | Project-local `.kimi-code/` install · [Get Kimi Code](https://www.kimi.com/code?aff=ecc) |
| CodeBuddy | `./install.sh --profile minimal --target codebuddy` | Project-local `.codebuddy/` install |
| JoyCode | `./install.sh --profile minimal --target joycode` | Project-local `.joycode/` install |

GitHub Copilot support is already included in this repository. `.github/copilot-instructions.md` provides the instruction layer, `.github/prompts/` contains the reusable `/plan`, `/tdd`, `/security-review`, `/build-fix`, and `/refactor` prompts, and `.vscode/settings.json` enables `chat.promptFiles`.

For a harness without a native ECC target, use the [manual adaptation guide](docs/MANUAL-ADAPTATION-GUIDE.md). It explains how to carry a small set of ECC skills and workflow instructions into chat-style tools without pretending hooks or native skill discovery are available.

Cursor installs agent definitions under `.cursor/agents/ecc-*.md`. Cursor-native loading behavior can vary by Cursor build. ECC does not install root `AGENTS.md` into `.cursor/`. The adapter keeps Cursor's context scoped to its native rules and agent surfaces.

Deep per-harness notes (feature parity, hook adapters, limitations) live in [Platform Support](#platform-support) below.
</details>

## Advanced Install Options

<details>
<summary><strong>Low-context install with no hook runtime</strong></summary>

### Low-context / no-hooks path

Use this when you want ECC's rules, agents, commands, platform config, and core workflows without runtime hooks:

```bash
npx ecc-universal@2.2.1 install --profile minimal --target claude
```

From a source checkout, the equivalent command is:

```bash
./install.sh --profile minimal --target claude
```

Windows:

```powershell
.\install.ps1 --profile minimal --target claude
```

This profile intentionally excludes `hooks-runtime`.

Claude manual installs place each skill directly under `~/.claude/skills/<skill-name>/` (or `.claude/skills/<skill-name>/` for `claude-project`) so Claude Code can discover it. When upgrading an older ECC manual install, the installer migrates only nested `skills/ecc/` files recorded in ECC install-state. If a flat skill directory is user-owned, ECC preserves it, prints a conflict warning, and keeps any older managed copy tracked for a safe uninstall instead of overwriting user files.

For the normal core profile with hooks disabled:

```bash
./install.sh --profile core --without baseline:hooks --target claude
./install.sh --profile core --no-hooks --target claude
```

Add the hook runtime later only if you want it:

```bash
./install.sh --target claude --modules hooks-runtime --enable-hooks
```

Any install whose profile or modules would materialize the hook runtime requires
an explicit decision. Without `--enable-hooks` or `--no-hooks`, the installer
prints what the hooks can do and stops before writing anything. The guided
installer (`ecc install --guided`) asks for this choice interactively.
</details>

<details>
<summary><strong>Choose only the components you need</strong></summary>

### Find the right components first

Ask the packaged advisor which components match your work:

```bash
node scripts/ecc.js 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.

You can also install explicit skills or capabilities:

```bash
./install.sh --target claude --skills tdd-workflow,security-review
node scripts/ecc.js install --profile minimal --target claude --with capability:machine-learning
```

Manual component-by-component copying also works. Each component is fully independent:

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

Retired shims live in `legacy-command-shims/`. Copy individual files from there only if you still need old names such as `/tdd`.
</details>

<details>
<summary><strong>Project-local rules instead of global rules</strong></summary>

Use project-local rules when ECC's standards should apply to one repository rather than every Claude Code session:

```bash
cd your-project
mkdir -p .claude/rules/ecc
cp -R /path/to/ECC/rules/common .claude/rules/ecc/
cp -R /path/to/ECC/rules/typescript .claude/rules/ecc/
```

Rules are always-loaded context, so begin with `common` and one pack for the stack you actually use. 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.
</details>

<details>
<summary><strong>Fully manual Claude install</strong></summary>

Use this only when you are intentionally skipping the plugin path:

```bash
git clone https://github.com/affaan-m/ECC.git
cd ECC
./install.sh --profile full
```

Windows:

```powershell
git clone https://github.com/affaan-m/ECC.git
cd ECC
.\install.ps1 --profile full
```

If you choose this path, stop there. Do not also run `/plugin install`.

For hand-picked manual installs, Claude discovers skills as direct children of `~/.claude/skills/`; do not nest them under `~/.claude/skills/ecc/`.

#### Install hooks

Do not copy the raw repo `hooks/hooks.json` into `~/.claude/settings.json` or `~/.claude/hooks/hooks.json`. That file is plugin/repo-oriented; use the installer so hook command paths are rewritten correctly:

```bash
bash ./install.sh --target claude --modules hooks-runtime --enable-hooks
```

That installs the hook scripts under `~/.claude/` and registers the resolved
hook entries in `~/.claude/settings.json`. Existing user settings and hooks are
preserved; ECC-owned entries are tracked by stable ID for idempotent updates
and safe uninstall.

If you installed ECC via `/plugin install`, do not copy those hooks into `settings.json`. Claude Code v2.1+ already auto-loads plugin `hooks/hooks.json`, and duplicating them in `settings.json` causes duplicate execution and cross-platform hook conflicts.

On Windows, Claude's config root is `%USERPROFILE%\.claude`; install the hook runtime with:

```powershell
pwsh -File .\install.ps1 --target claude --modules hooks-runtime --enable-hooks
```

#### Configure MCPs

Claude plugin installs intentionally do not auto-enable ECC's bundled MCP server definitions. This avoids overlong plugin MCP tool names on strict third-party gateways while keeping manual MCP setup available.

Use Claude Code's `/mcp` command or CLI-managed MCP setup for live Claude Code server changes; Claude Code persists those choices in `~/.claude.json`. For repo-local MCP access, copy desired MCP server definitions from `mcp-configs/mcp-servers.json` into a project-scoped `.mcp.json`.

ECC ships exactly one default connector (`chrome-devtools`); everything else is a skill wrapping a CLI/REST API or an opt-in catalog entry. The rule and the June 2026 audit that retired the previous six defaults live in [docs/MCP-CONNECTOR-POLICY.md](docs/MCP-CONNECTOR-POLICY.md).

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

```bash
export ECC_DISABLED_MCPS="chrome-devtools"
```

ECC-managed install and Codex sync flows will skip or remove those bundled servers instead of re-adding duplicates. `ECC_DISABLED_MCPS` is an ECC install/sync filter, not a live Claude Code toggle.

**Important:** Replace `YOUR_*_HERE` placeholders with your actual API keys.
</details>

<details>
<summary><strong>Multi-model commands require additional setup</strong></summary>

`multi-*` commands are **not** covered by the base plugin/rules install.

To use `/multi-plan`, `/multi-execute`, `/multi-backend`, `/multi-frontend`, and `/multi-workflow`, you must also install the `ccg-workflow` runtime. Choose and review an exact release using the [upstream CCG installation guide](https://github.com/fengshao1227/ccg-workflow#readme), then initialize that installed runtime. ECC does not bundle CCG or attest to a compatible, audited CCG release; this guide does not bootstrap an unspecified registry version.

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.
</details>

<details>
<summary><strong>Reset, repair, or uninstall</strong></summary>

### Reset / Uninstall ECC

If you installed from the universal package, run these commands from the same
project directory used for installation:

```bash
npx ecc-universal@2.2.1 list-installed
npx ecc-universal@2.2.1 doctor
npx ecc-universal@2.2.1 repair
npx ecc-universal@2.2.1 uninstall --dry-run
npx ecc-universal@2.2.1 uninstall
```

From a source checkout, inspect the managed state before reinstalling:

```bash
node scripts/ecc.js list-installed
node scripts/ecc.js doctor
node scripts/ecc.js repair
node scripts/ecc.js uninstall --dry-run
```

For a direct source-checkout uninstall:

```bash
node scripts/uninstall.js --dry-run
node scripts/uninstall.js
```

If you are leaving, the uninstall command prints an optional [20-second feedback form](https://github.com/affaan-m/ECC/issues/new?template=quick-feedback.yml). It is a public GitHub issue, never blocks uninstall, and ECC does not upload diagnostics. You can also run `ecc feedback` at any time to see the problem, feedback, and feature routes.

Plugin users should remove the plugin from Claude Code, then delete only the rule folders they manually copied and no longer want. ECC only removes files recorded in its install-state. It does not claim unrelated files in your harness directories.

If you stacked methods, clean up in this order:

1. Remove the Claude Code plugin install.
2. Run the ECC uninstall command from the project directory that contains the managed install-state.
3. Delete any extra rule folders you copied manually and no longer want.
4. Reinstall once, using a single path.

## Start Using ECC

Start with the workflow you need, not the full catalog.

| What you are doing | Start here |
|---|---|
| Building a feature | `/ecc:plan "describe the feature"`, then `tdd-workflow` |
| Fixing a bug | Reproduce it with a failing test, then use `tdd-workflow` |
| Reviewing new code | `/code-review` for a fresh-context review |
| Repairing a build | `/build-fix` |
| Cleaning a codebase | `/refactor-clean` |
| Checking context pressure | `/context-budget` |
| Ending a long session | `/save-session` or `/learn-eval` |
| Resuming later | `/resume-session` |
| Auditing agent config | `/security-scan` with a reviewed scanner, or installed `agentshield scan --path .` |

<details>
<summary><strong>Plugin commands and manual commands</strong></summary>

Claude Code plugin commands use the namespaced form:

```text
/ecc:plan "Add authentication"
```

Manual installs may expose the shorter compatibility form:

```text
/plan "Add authentication"
```

Skills are the primary workflow surface. Commands remain convenient entry points and compatibility shims. Check what is installed with:

```bash
/plugin list ecc@ecc
```
</details>

<details>
<summary><strong>Which agent should I use?</strong></summary>

Skills are the canonical workflow surface; maintained slash entries stay available for command-first workflows.

| I want to... | Use this surface | 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-workflow` skill | 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-testing` skill | 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 F# code | *(invoke `fsharp-reviewer` directly)* | fsharp-reviewer |
| Review TypeScript/JavaScript code | *(invoke `typescript-reviewer` directly)* | typescript-reviewer |
| Develop HarmonyOS apps | *(invoke `harmonyos-app-resolver` directly)* | harmonyos-app-resolver |
| Audit database queries | *(auto-delegated)* | database-reviewer |
| Review production ML changes | `mle-workflow` skill + `mle-reviewer` agent | mle-reviewer |

<summary><strong>Common workflows</strong></summary>

Slash forms below are shown where they remain part of the maintained command surface. Retired short-name shims such as `/tdd` and `/eval` live in `legacy-command-shims/` for explicit opt-in only.

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

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

**Preparing for production:**
```

e2e-testing skill                             -> e2e-runner: critical user flow tests
/test-coverage                                -> verify 80%+ coverage
```
</details>

## Self-Hosted Models and Custom Endpoints

ECC works through each harness's normal configuration, so you can use an official provider, a compatible custom API endpoint or model gateway, or a self-hosted model without changing ECC's workflows.

For Claude Code, ECC does not hardcode Anthropic-hosted transport settings. Minimal gateway 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. See Anthropic's [LLM gateway documentation](https://docs.anthropic.com/en/docs/claude-code/llm-gateway) and [model configuration documentation](https://docs.anthropic.com/en/docs/claude-code/model-config).

Run or self-host any open-source model behind that gateway using separate compute and serving setup. If you need GPU capacity, [Itô](https://compute.itomarkets.com) is ECC's preferred compute sponsor; any GPU provider works. The sponsorship link is passive: it does not invoke an RFQ, reserve capacity, provision compute, or configure serving. Separately, `ecc ito find` invokes the explicitly configured canonical Itô CLI and submits a live authenticated RFQ; it does not reserve capacity. Managed inference through Itô is not live yet.

### Self-host Kimi with ECC + Itô compute

The Kimi Code harness and the model-serving layer are separate. ECC configures the agent harness; you bring an API endpoint ([get a Kimi API key](https://platform.kimi.ai?aff=ecc)) or self-host an open-weight Kimi model on your own GPU capacity. This adapter is verified against Kimi Code 0.31.x (`@moonshot-ai/kimi-code`):

<table aria-label="Local Kimi model path" width="100%">

  </a><br />
  <sub>Install project instructions and skills, then start Kimi Code.</sub>
</td>
</tr>
</table>

Configure the endpoint with Kimi Code's <a href="https://moonshotai.github.io/kimi-cli/en/configuration/providers.html">official provider guide</a>, then install ECC:

```bash
bash ./install.sh --target kimi --profile minimal
node scripts/ecc.js doctor --target kimi
kimi
```

Kimi Code discovers the installed `.kimi-code/AGENTS.md` instructions and `.kimi-code/skills/` workflows natively; project-level `.agents/skills/` is also an official discovery location. ECC safely merges project MCP entries into `.kimi-code/mcp.json` and does not change the user-level `~/.kimi-code/config.toml`. Kimi Code supports native hooks, but ECC's current managed-project adapter does not configure them, so this installer does not offer Kimi hook profiles. The installer dry-run and regression suite verify that every managed Kimi write stays inside the project-local `.kimi-code/` root.

### Itô compute CLI bridge

`ecc ito` delegates to the separately installed canonical Itô client; ECC does not maintain a second API client. `ecc ito login [--no-browser]` performs device authorization, opens the Itô verification page by default, and persists a device token in macOS Keychain; `--no-browser` suppresses the page handoff. ECC itself does no browser automation. `ecc ito auth` is validation-only and rejects `--no-browser`. The available operations are `ecc ito login`, `ecc ito auth`, `ecc ito find`, `ecc ito status`, and the separately gated `ecc ito evals`. The matching MCP tools remain `ito_auth`, `ito_find`, and `ito_status`; `ito_auth` validates existing credentials and node qualification is CLI-only.

The `ito-compute-cli` package is currently unpublished. Build it locally from the Itô runtime repo (private while the desk hardens; design partners get access) under `cli/ito-compute-cli`, run `npm ci` and `npm run check`, then set `ECC_ITO_CLI_EXECUTABLE` to that build's absolute `dist/bin/ito.js` path. Login never inherits `ITO_API_KEY`; auth, find, and status forward `ITO_API_KEY` directly when configured, and `ITO_AUTH_MODE=legacy` is not required. `ecc ito logout` revokes the current device credential and retains its local copy if remote revocation cannot be confirmed. Device tokens use macOS Keychain by default; explicit file fallback must retain owner-only directory/file permissions. ECC does not discover this credential-bearing client through `PATH`. See the [`ito-compute` skill](skills/ito-compute/SKILL.md) for the full RFQ authority and MCP setup contract.

`find` submits a live authenticated RFQ. It does not reserve capacity. `evals` requires both `ITO_ENABLE_SIXTYTWO_LIVE=1` and `--live-sixtytwo`, a separately installed `sixtytwo-cli==0.3.33`, an explicit node list, and an existing absolute configuration directory. It cannot rent, launch, recover, repair, or purchase. ECC exposes no quote lock, purchase, workload, or inference path, and it never replaces a missing client or failed live call with a local result.

## What's New

Current release: **2.2.1** (2026-08-31). Highlights of the 2.2 line:

- Guided, manifest-driven setup across Claude Code, Codex, and Kimi Code, with install-state ownership, doctor, repair, and uninstall.
- Native Antigravity install, a thin Pi adapter, and the packed-artifact release gate tested on Linux, macOS, and Windows.
- Plan Canvas browser review, the unified memory vault (`ecc memory`), and the Itô compute skill family.

### v2.0.0: The Agent Harness Operating System (Jun 2026)

Stable graduation of the 2.0 line: control-pane substrate, worktree lifecycle service, the `orch-*` orchestrator family, and the Discord community. Notes: [docs/releases/2.0.0/release-notes.md](docs/releases/2.0.0/release-notes.md).

## Key Concepts

<details>
<summary><strong>Agents, skills, hooks, and rules explained</strong></summary>

### 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 maintained `commands/` during migration, while retired short-name shims live under `legacy-command-shims/` for explicit opt-in only. 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
  arkts/           # HarmonyOS / ArkTS patterns and constraints
```

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