Diagnoses Grammarly API errors like 400/401/413/429 with fixes for auth, chunking, backoff. Includes curl tests for connectivity and scoring endpoint.
npx claudepluginhub jeremylongshore/claude-code-plugins-plus-skills --plugin grammarly-packThis skill is limited to using the following tools:
**Cause:** Text has fewer than 30 words.
Executes Grammarly API outage triage: curl health checks, severity classification, TypeScript fallback implementation.
Guides Next.js Cache Components and Partial Prerendering (PPR): 'use cache' directives, cacheLife(), cacheTag(), revalidateTag() for caching, invalidation, static/dynamic optimization. Auto-activates on cacheComponents: true.
Guides building MCP servers enabling LLMs to interact with external services via tools. Covers best practices, TypeScript/Node (MCP SDK), Python (FastMCP).

Cause: Text has fewer than 30 words. Fix: Ensure minimum 30 words. Pad short texts with context if needed.
Cause: Token expired or invalid. Fix: Re-authenticate with client credentials grant.
Cause: Text exceeds 100,000 characters or 4 MB.
Fix: Split into chunks using paragraph boundaries. See grammarly-sdk-patterns for chunking function.
Cause: Rate limit exceeded.
Fix: Implement exponential backoff. See grammarly-rate-limits.
Cause: Large document processing or service delay. Fix: Poll every 3-5 seconds, timeout after 90 seconds.
Cause: Short text produces unreliable results. Fix: AI detection works best on 200+ words. Scores on short text are less reliable.
