meta-ads-audit
作为系列首步，生成可复用的业务上下文供其它技能使用
需要 OAuth 授权读取广告账户数据
诊断 Meta（Facebook/Instagram）广告账户健康并保存可复用的业务上下文（只读）。
先跑一次会把 Meta（Facebook/Instagram）账号的业务信息抓一遍，诊断账户健康并把可复用的业务上下文保存为只读文件，供后续功能复用。通常在第一次接入或发现缺少 meta business-context.json 时使用。特别之处是只读分析不改账号，只给出修复建议，真正修改需要用户按建议去执行。

Meta Ads (Facebook + Instagram) account audit and business context setup. Run this first — it gathers business information, analyzes account health, and saves context that all other Meta ads skills reuse. Trigger on "audit my Meta ads", "audit my Facebook ads", "Meta ads audit", "set up my Meta ads", "onboard Meta", "Meta account overview", "how's my Meta account", "Meta health check", "what should I fix in my Facebook ads", or when the user is new to NotFair Meta and hasn't run an audit before. Also trigger proactively when other Meta ads skills detect that meta business-context.json is missing.

Diagnose Meta (Facebook + Instagram) account health and persist business context for downstream skills (`/meta-ads`). **Read-only** — never mutates the account. The user runs `/meta-ads` to execute fixes you recommend.
## Setup
Follow `../shared/preamble.md` — MCP detection, OAuth, ad account selection.
## Filesystem contract (MUST persist)
| Artifact | Path | When |
|---|---|---|
| Business context | `{data_dir}/meta/business-context.json` | First full audit, or refresh when `audit_date` is >90 days old. Skip on scoped audits if file is fresh. |
| Personas | `{data_dir}/meta/personas/{accountId}.json` | Every full audit. |
These are the handoff to `/meta-ads` — write
