auth-preflight skillA

auth-preflight is agent-read markdown (skill) from ai-analyst-lab/ai-analyst: Verify Google Workspace MCP authentication at the start of any session that needs Google APIs (Docs, Slides, Drive). This skill prevents auth failures mid-workflow by testing credentials upfront. Use this skill automatically at session start when the task involves Google Docs, Google Slides, Drive uploads, or any MCP Google Workspace tool. Also trigger when users mention "Google Doc", "Google Slides", "upload to Drive", "export to Google", "share on Drive", or any Google-related output format. A.

What the file says

# Skill: Auth Preflight

## Purpose

Verify Google Workspace MCP authentication BEFORE beginning any Google-dependent work. Catches auth issues in <30 seconds instead of discovering them after 5-10 minutes of chart generation, narrative writing, or deck building.

**Core principle:** Fail fast with clear guidance, not slow with cryptic errors mid-workflow.

## When to Apply

Trigger this skill immediately when:
- The task involves Google Docs, Slides, or Drive
- Any `mcp__google-*` tool will be called
- The user mentions "Google Doc", "Google Slides", "upload to Drive", "create a deck", "export to Google", "share on Drive"
- Before running google-slides-creator, google-slides-reviewer, gdoc-builder, or any Google-dependent agent

**Critical timing:** Run auth preflight as your FIRST action, before exploring data, generating charts, parsing narratives, or any other substantive work.

## Preflight Workflow

### Step 1: Detect MCP Configuration

Read `.mcp.json` to discover which Google MCP server(s) are configured:

```bash
cat .mcp.json | grep -A3 google
```

Look for entries like:
- `google-docs` → Google Docs + Drive MCP server (most common)
