gsd-framework-selector

gsd-framework-selector is an agent for Claude Code from open-gsd/gsd-core. It costs 55 tokens per session (1,095 once invoked), scanned A, original, MIT.

An interactive decision tool that asks about an AI system and compares suitable AI frameworks, which are software libraries for building applications with language models.

In plain words
What is it for?
It recommends frameworks for systems such as document question-answering, chatbots, multi-agent workflows, structured extraction, and code automation.
Why use it?
It helps teams choose a framework using their use case, model provider, language, existing libraries, and team context instead of choosing blindly.

About the project

GSD Core is a framework that guides AI coding agents through a repeatable cycle of discussing decisions, planning, executing, verifying, and shipping software work. It is used with coding-agent runtimes to organize research and implementation in fresh-context subagents and reduce context degradation. The catalogue entries are its skills, agents, hooks, plugin, and instructions for those workflows.

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

gsd-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 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.

# question (header) multiSelect options
1 What type of AI system are you building? (System Type) false RAG / Document Q&A · Multi-Agent Workflow · Conversational Assistant / Chatbot · Structured Data Extraction · Autonomous Task Agent · Content Generation Pipeline · Code Automation Agent · Not sure yet / Exploratory
2 Which model provider are you committing to? (Model Provider) false OpenAI (GPT-4o, o3, etc.) · Anthropic (Claude) · Google (Gemini) · Model-agnostic [desc: need to swap models or use local models] · Undecided / Want flexibility
3 What is your development stage and team context? (Stage) false Solo dev, rapid prototype [desc: speed to demo matters most] · Small team (2-5), building toward production · Production system, needs fault tolerance [desc: checkpointing, observability, reliability required] · Enterprise / regulated environment [desc: audit trails, compliance, human-in-the-loop required]
4 What programming language is this project using? (Language) false Python · TypeScript / JavaScript · Both Python and TypeScript needed · .NET / C#
5 What is the most important requirement? (Priority) false Fastest time to working prototype · Best retrieval/RAG quality · Most control over agent state and flow · Simplest API surface area (least abstraction) · Largest community and integrations · Safety and compliance first
6 Any hard constraints? (Constraints) true No vendor lock-in · Must be open-source licensed · TypeScript required (no Python) · Must support local/self-hosted models · Enterprise SLA / support required · No new infrastructure (use existing DB) · None of the above

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.
