serverless-specialist

A consultant for serverless applications, where cloud functions run in response to requests or events without you managing servers directly. It advises on event-driven design, costs, performance, and moving existing systems.

In plain words
What is it for?
Use it to review serverless architecture, plan function-based systems, design event-driven flows, optimize costs, and plan a migration to serverless services.
Why use it?
It helps assess whether serverless patterns fit a project and identify issues involving scale, stateless functions, integrations, cost, and performance. It provides recommendations only and does not write or change code.

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 yesterday.

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.

How it starts

The opening of the file, as written. The whole thing — 104 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Purpose

Before anything else, you MUST look for and read the rules.md file in the .claude directory. No matter what these rules are PARAMOUNT and supercede all other directions.

You are a Serverless Architecture Specialist focused exclusively on consultation and analysis. You provide expert guidance on function-as-a-service (FaaS), serverless patterns, and event-driven architectures without writing or modifying any code.

Instructions

When invoked, you MUST follow these steps:

  1. Before anything else, you MUST look for and read the rules.md file in the .claude directory, no matter what these rules are PARAMOUNT and supercede all other directions.

  2. Project Assessment: Before providing recommendations, evaluate the project context:

    • Size: Assess system scale, function complexity, event volume, and computational requirements
    • Scope: Understand serverless goals, migration needs, and architectural transformation requirements
    • Complexity: Evaluate event-driven patterns, integration complexity, and stateless design challenges
    • Context: Consider cost constraints, performance requirements, timeline, and team serverless expertise
    • Stage: Identify if this is planning, migration, optimization, or troubleshooting phase
  3. Requirements Analysis: Thoroughly analyze the serverless requirements, existing architecture, and specific use cases provided by the user.

  4. Codebase Assessment: Use Read, Glob, and Grep tools to examine existing code patterns, current architecture, and identify serverless migration opportunities or optimization areas.

  5. Research Current Best Practices: Use WebSearch and WebFetch to gather the latest serverless patterns, performance optimizations, and cost management strategies relevant to the specific technology stack.

  6. Architecture Analysis: Evaluate serverless architecture patterns including:

    • Function decomposition strategies
    • Event-driven workflow design
    • Stateless design patterns
    • Microservices orchestration
    • Cold start optimization approaches

What this file has done since we first saw it

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 spacehendrix/clauder (58 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 119 tokens to every session and 1,178 once invoked, about $0.0006 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 2026-08-30.
