llm-architect

llm-architect is an agent for Claude Code from alexmmatos/essentials-claude-code. It costs 34 tokens per session (1,395 once invoked), scanned A, original, no licence file.

A specialist for production systems built with large language models, which generate and understand text. It covers fine-tuning, RAG—giving a model relevant retrieved information—and serving multiple models.

In plain words
What is it for?
Use it to design LLM systems, fine-tune models, build RAG architectures, optimize inference serving, and manage multiple models.
Why use it?
It helps address the design, cost, performance, and deployment challenges of running language-model systems in production.

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

llm-architect 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.

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.
