backend-pro-max-skill: Skill for Claude Code

.claude/skills/backend-pro-max/SKILL.md

backend-pro-max is a skill for Claude Code from shashankswe2020-ux/backend-pro-max-skill. It costs 72 tokens per session (391 once invoked), scanned A, original, MIT.

A command-line reference tool for backend, cloud, and distributed-systems engineering, with guidance organized by technical topic and programming language.

In plain words
What is it for?
Use it to query language or framework practices, investigate architecture and infrastructure choices, and get guidance on APIs, security, scaling, performance, and operations.
Why use it?
It reduces the need to remember or manually search for stack-specific advice about errors, concurrency, databases, deployment, testing, and reliability.

Skill for Claude Code

Written for Claude Code: installed under .claude/.

This is shashankswe2020-ux/backend-pro-max-skill's own configuration. It tells Claude Code how to work on backend-pro-max-skill itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything backend-pro-max-skill configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python3 src/backend-pro-max/scripts/search.py "<query>" [--domain <domain>] [--stack <stack>] [-n N].

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

backend-pro-max 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 11d 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.

What it actually says

Backend Pro Max

Use this skill whenever the user asks about backend, cloud, or distributed-systems engineering — choosing a language / database / broker, designing an API, sizing a cache, planning multi-region, debugging tail latency, hardening security, defining SLOs, etc.

python3 src/backend-pro-max/scripts/search.py "<query>" [--domain <domain>] [--stack <stack>] [-n N]
python3 src/backend-pro-max/scripts/search.py "<query>" --all
python3 src/backend-pro-max/scripts/search.py --list

Working principles

  1. Run a --stack <stack> query first if the user has named a language / framework. The stack CSV contains the strict guidelines for that ecosystem (concurrency, errors, build, testing, …) — follow them.
  2. Then run a --domain <domain> query to pull the right architectural pattern, infra component, or operational practice.
  3. Be explicit about consistency, idempotency, retries, timeouts, and failure handling in any code or design you produce.
  4. Default to managed services unless there is a concrete reason to self-host.
  5. Wire observability and security from the start — never bolt on later.

See src/backend-pro-max/templates/base/quick-reference.md for the full domain/stack catalogue and example queries.

Changes

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.
