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 9d 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.

backendpro "<query>" [--domain <domain>] [--stack <stack>] [-n N]
backendpro "<query>" --all
backendpro --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.

Run backendpro --list for the full domain/stack catalogue.

Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
