# compose-doctor

A skill that diagnoses broken Goldsky Compose apps: failing tasks, crashloops, missed events, bundler and wallet errors. Useful once an app is deployed and something stops working.

## What it does

The skill walks a fixed path: auth check, app lookup, status, logs, secrets, wallets, manifest, diagnosis, fix. At each step it runs `goldsky compose` commands and reads the output instead of handing you a command list. Without a `Bash` tool it prints the commands and asks you to paste the output back.

Log matching is an exact substring check against the `.message` field when `--json` is set. One trap matters here: `--json` commands write failures to stderr as `{"error":true,"code":"<CODE>","message":"..."}` and exit 1, so an agent reading stdout alone sees nothing and mis-diagnoses. Secret values are never retrievable — they are encrypted end-to-end and `secret list` returns names only.

This skill fixes existing apps. New ones go through `/compose`, CLI and manifest lookups live in `skills/compose/references/`, and secret management belongs to `/secrets`. Turbo, Mirror and Subgraph problems have their own skills, so don't expect this one to cover them.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add goldsky-io/goldsky-agent --skill compose-doctor -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add goldsky-io/goldsky-agent --skill compose-doctor -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add goldsky-io/goldsky-agent --skill compose-doctor -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install goldsky-io/goldsky-agent compose-doctor
```

2. **Manually: put the files in place**
- File: `.github/skills/compose-doctor/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add goldsky-io/goldsky-agent --skill compose-doctor -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/goldsky-io/goldsky-agent --path skills/compose-doctor
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add goldsky-io/goldsky-agent --skill compose-doctor -a opencode
```

### Claude.ai

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

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/goldsky-io/goldsky-agent/tree/HEAD/skills/compose-doctor/SKILL.md

## When to use it
- trace a failing task through logs and run history
- work out why cron never fires or events go missing
- fix a bundler error or a rejected manifest
- cross-check declared secrets against the ones that actually exist
- explain a reverted transaction or a gas sponsorship failure

## Example prompts
- my-app is failing, check the status and logs and tell me what broke
- Why isn't cron firing for my-app? Look at the runs from the last hour
- The transaction reverted with Transaction Receipt failed with status — find the failed run and the reason

description: "Diagnose an existing Goldsky Compose app with failing tasks, crashloops, missed events, cron not firing, HTTP 500s, wallet or gas sponsorship failures, missing secrets, bundler errors, manifest validation failures, or esbuild failures. Use when an app is named alongside a problem involving goldsky compose, including 'No bundler provider available', named wallets without a private key in local dev, and 'Transaction Receipt failed with status'. Load /compose first; inspect status, logs, secrets, and wallets to find the cause. New apps belong in /compose; reference-only lookups use skills/compose/references/. Use /secrets for secret management and /auth-setup for login. Turbo, Mirror, Subgraph, and Edge issues have separate skills."

# Compose Doctor

Diagnose and fix broken Compose apps. Workflow-oriented: we walk through auth → app identification → status → logs → secrets → wallets → manifest → diagnosis → fix. Part of the Compose skill family: /compose is the entry point, `skills/compose/references/` is the lookup layer, and this skill is the debugger.

## Boundaries

- Diagnose and fix EXISTING Compose apps interactively.
- Do not build new apps. Use `/compose` for that.
- Do not serve as a CLI/manifest reference. Read `skills/compose/references/`.
- For secrets creation/management mechanics, use `/secrets`. But DO check whether required secrets exist as part of diagnosis.
- Do not handle Turbo, Mirror, or Subgraph pipeline problems. Use `/turbo-doctor`, `/mirror-doctor`, or `/subgraph-doctor`.

## Mode Detection

Before running any commands, check if you have the `Bash` tool available:

- **If Bash is available** (CLI mode): Execute commands directly and parse output.
- **If Bash is NOT available** (reference mode): Output commands for the user to run. Ask them to paste the output back so you can analyze it and provide recommendations.

## Diagnostic Workflow

### Step 1 — Verify Auth

`goldsky project list 2>&1`. If not logged in, use `/auth-setup`.

### Step 2 — Identify the App

`goldsky compose list`. Confirm the app exists and note its current status.

### Step 3 — Check Status

`goldsky compose status -n <app>` or `goldsky compose status -n <app> --json`.

Statuses the CLI renders: RUNNING, PAUSED, STARTING, STOPPING, ERROR, NOT_FOUND (the value comes from the API, so treat the list as non-exhaustive). Decision tree:

- **RUNNING** but misbehaving → Step 4 (logs).
- **ERROR** → Step 4 (logs) is the fastest path.
- **PAUSED** → ask if intentional. `goldsky compose resume -n <app>` if not.
```
