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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.01506 | $0.01506 |
| Opus 5 | $0.00753 | $0.00753 |
| Sonnet 5 | $0.00301 | $0.00301 |
| Haiku 4.5 | $0.00151 | $0.00151 |
Grade A, and why
backend-pro-max-skill CLAUDE.md 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 10d 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.
How it starts
The opening of the file, as written. The whole thing — 157 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) and other AI coding assistants when working with this repository.
Project Overview
Backend Pro Max is an AI skill that provides backend / distributed-systems engineering intelligence: searchable knowledge bases for programming languages, databases, message brokers, caching, cloud, IaC, containers, observability, API design, auth, security, CI/CD, testing, architecture, scaling, consistency, performance, reliability, and data engineering — plus language-specific stack guidelines.
It is intended to be installed as a skill / rules file in any AI coding assistant (Claude Code, Cursor, Windsurf, Copilot, Gemini, etc.).
Search Command
python3 src/backend-pro-max/scripts/search.py "<query>" --domain <domain> [-n <max_results>]
python3 src/backend-pro-max/scripts/search.py "<query>" --stack <stack>
python3 src/backend-pro-max/scripts/search.py "<query>" --all # cross-domain
python3 src/backend-pro-max/scripts/search.py compare "<A>" "<B>" [--domain <d>] # side-by-side
python3 src/backend-pro-max/scripts/search.py --stale --domain <d> --max-age-months 18
python3 src/backend-pro-max/scripts/search.py --interactive # REPL
python3 src/backend-pro-max/scripts/search.py --list # list domains & stacks
If installed as a package (pip install -e .):
backendpro "<query>"
backendpro compare "Kafka" "RabbitMQ" --domain messaging
backendpro --interactive
backendpro-validate # validate every CSV against its schema
Useful flags
--max-results / -n N— cap returned rows (default 5).--min-score F— drop weak matches (BM25 score ≤ F).--max-age-months N— drop rows whoseLast Updatedis older than N months.--no-expand— disable synonym expansion (e.g.partial failure → compensation, saga).--no-scores— hide BM25 confidence scores in markdown output.--json— machine-readable output (always includes_score).
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.

backend-pro-max-skill CLAUDE.md is an instructions file published in the GitHub repository shashankswe2020-ux/backend-pro-max-skill (5 stars, last pushed 4mo ago), licensed MIT. It adds 1,506 tokens to every session, about $0.0075 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 2026-08-31.
