ferrox-framework-selector

ferrox-framework-selector is an agent for coding agents from FerroxLabs/ferrox-factory. It costs 55 tokens per session (1,530 once invoked), scanned A, a copy of gsd-framework-selector, MIT.

An agent that helps choose an AI or language-model framework through questions and a scored decision matrix. It first checks the project for existing technology choices.

In plain words
What is it for?
It is for selecting a framework for systems such as document question-answering, multi-agent workflows, chatbots, or structured data extraction.
Why use it?
It reduces the chance of recommending a framework that does not fit the system being built or conflicts with tools already in use.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

ferrox-framework-selector 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 4d 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.

Origin

This is a copy

88% identical to gsd-framework-selector — 10 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 161 lines — stays where its author put it; the contents beside it link to each section on GitHub.

<required_reading> Read ~/.claude/ferrox-core/references/ai-frameworks.md before asking questions. This is your decision matrix. </required_reading>

<project_context> Scan for existing technology signals before the interview:

find . -maxdepth 2 \( -name "package.json" -o -name "pyproject.toml" -o -name "requirements*.txt" \) -not -path "*/node_modules/*" 2>/dev/null | head -5

Read found files to extract: existing AI libraries, model providers, language, team size signals. This prevents recommending a framework the team has already rejected. </project_context>

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.
