## What it does

The skill handles one task per run and talks to `executor.sh/mcp`, a proxy fronting whatever the operator wired up: upstream MCP servers, OpenAPI specs, GraphQL endpoints. Credentials stay in Executor and get attached upstream on each call, so the agent never holds them. Tool discovery happens on every run — the catalog is only as big as what you connected.

You need the OAuth Connect from the dashboard MCP panel, requested with `offline_access`. Tokens are kept as `MCP_EXECUTOR_TOKEN` and `MCP_EXECUTOR_OAUTH` and refreshed by `scripts/mcp-oauth-refresh.sh` before each run. When that refresh fails and tools answer 401, the skill stops with `EXEC_AUTH_STALE` and asks you to reconnect the server. With no connection at all there are no `mcp__executor__*` calls to make, and it exits with `EXEC_NOT_CONNECTED`.

Each call lands in one of three states. Allowed calls return a result. A call awaiting approval parks until a human clears it in the Executor console — the skill does not retry it, finishes what the remaining tools allow, and reports the pending link. Blocked calls stay blocked; routing around them with another tool is off the table. Writes are real side effects, so an irreversible one is sequenced last. The run caps at 15 calls because the upstreams behind the proxy are rate-limited and may be metered.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add aeonfun/aeon --skill executor-mcp -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/executor-mcp/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/executor-mcp/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add aeonfun/aeon --skill executor-mcp -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/executor-mcp/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add aeonfun/aeon --skill executor-mcp -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/executor-mcp/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install aeonfun/aeon executor-mcp
```

2. **Manually: put the files in place**

npx skills add aeonfun/aeon --skill executor-mcp -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/aeonfun/aeon --path skills/executor-mcp
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/executor-mcp/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add aeonfun/aeon --skill executor-mcp -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

## When to use it
- collapse a pile of integrations into one MCP endpoint
- list which integrations are connected right now
- call an external API without handing the agent credentials
- hold a risky write until a human approves it
- report which tools actually ran during the task

## Example prompts
- What integrations are connected in Executor?
- List my open Linear issues and summarize by project.
- Run this through the Executor catalog: pull the open issues and group them by project.

> **${var}** — the task to run against the Executor catalog, e.g. `list my open Linear issues and summarize by project` or `what integrations are connected?`. Required. If empty, log `EXEC_NO_TASK` and exit cleanly (no notify).

Execute one task through **Executor Cloud** (`executor.sh/mcp`) — a proxy that fronts every integration the operator connected (upstream MCP servers, OpenAPI specs, GraphQL endpoints) as a single tool catalog. Credentials live in Executor and are attached upstream per call; this agent never sees them. Every call is governed by a per-tool policy: **allow**, **require approval**, or **block**.

## Detection & auth

The server is wired by the dashboard MCP panel's one-click **Connect** (OAuth with `offline_access`; tokens stored as `MCP_EXECUTOR_TOKEN` + `MCP_EXECUTOR_OAUTH`, refreshed each run by `scripts/mcp-oauth-refresh.sh`). Its tools surface as `mcp__executor__*` — the catalog is whatever the operator connected, so **discover it from the server every run**; never assume an integration exists.

- **No `mcp__executor__*` tool callable** → the server isn't connected (or its secrets are missing, in which case the workflow logged a `::warning::` and skipped MCP). Log `EXEC_NOT_CONNECTED`, notify once pointing the operator at the dashboard → MCP → Connect Executor, and exit.
- **Tools exist but return 401/invalid-token** → the OAuth refresh failed (see `docs/mcp-oauth.md`). Log `EXEC_AUTH_STALE`, notify the operator to re-connect the server once in the dashboard, and exit.

## Steps

### 1. Discover the catalog

Enumerate the tools Executor exposes and map `${var}` onto them. If the task is a pure catalog question (`what integrations are connected?`), answer from discovery alone — that's a complete run. If the task needs an integration that isn't in the catalog, log `EXEC_NO_INTEGRATION`, notify which integration is missing (the operator adds it in the Executor console at executor.sh), and exit — don't improvise a substitute.

### 2. Execute
```
