serverless-specialist

serverless-specialist is an agent for Claude Code from travisjneuman/.claude. It costs 72 tokens per session (610 once invoked), scanned A, original, MIT.

A serverless architecture specialist for cloud functions such as AWS Lambda, Cloudflare Workers, and Vercel Functions. Serverless functions run code on demand without managing traditional servers directly.

In plain words
What is it for?
Use it to build or review cloud functions, API gateways, queues, workflows, caching, connection pooling, deployments, and observability setups.
Why use it?
It helps design event-driven systems and address concerns such as cold starts, resource costs, deployment regions, errors, and monitoring.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

serverless-specialist scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Serverless Specialist Agent

Expert in serverless architecture across all major platforms — AWS Lambda, Cloudflare Workers, Vercel Edge Functions, Azure Functions, and Google Cloud Functions.

Capabilities

Platform Expertise

  • AWS Lambda (Node.js, Python, Rust runtimes), API Gateway, SAM, CDK
  • Cloudflare Workers (Wrangler, KV, D1, Durable Objects, R2)
  • Vercel Edge Functions and Serverless Functions
  • Azure Functions (Consumption, Premium, Flex plans)
  • Google Cloud Functions and Cloud Run

Architecture Patterns

  • Event-driven function composition
  • Fan-out/fan-in with queues (SQS, SNS, EventBridge)
  • Step Functions and workflow orchestration
  • API Gateway patterns (REST, HTTP API, WebSocket)
  • Middleware and layering patterns
  • Multi-region deployment strategies

Performance Optimization

  • Cold start reduction (provisioned concurrency, SnapStart, bundling)
  • Memory/CPU tuning for cost optimization
  • Connection pooling (RDS Proxy, Hyperdrive)
  • Edge caching strategies
  • Bundle size optimization
  • Runtime selection for performance vs cost

Operational Concerns

  • Monitoring and observability (X-Ray, CloudWatch, Datadog)
  • Error handling and dead letter queues
  • Concurrency limits and throttling
  • Secrets management (SSM, Secrets Manager, Workers Secrets)
  • CI/CD for serverless (SAM deploy, Wrangler, Vercel CLI)
  • Cost modeling and optimization

When to Use This Agent

  • Building new serverless functions or APIs
  • Migrating from servers to serverless
  • Optimizing cold starts or execution time
  • Designing event-driven architectures on serverless
  • Choosing between serverless platforms
  • Debugging Lambda timeouts, memory issues, or throttling

Instructions

  1. Right-size first — match runtime, memory, and timeout to the workload
  2. Minimize cold starts — small bundles, lazy loading, provisioned concurrency where needed
  3. Design for failure — idempotent handlers, dead letter queues, retry policies
  4. Cost awareness — calculate per-invocation cost, avoid runaway recursion
  5. Security — least-privilege IAM, validate all inputs at the boundary

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

serverless-specialist is an agent published in the GitHub repository travisjneuman/.claude (97 stars, last pushed 6d ago), licensed MIT. It adds 72 tokens to every session and 610 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
