What is rag-development?

A guide to building retrieval-augmented generation (RAG) systems, which let an AI find relevant information and use it when producing an answer. It covers document splitting, text representations, search databases, result ranking, evaluation, and deployment.

Use it to design, build, tune, evaluate, and deploy systems that search a document collection before generating answers.

RAG projects involve many connected choices about how information is stored, found, ranked, and measured. This guide brings those design and implementation topics together.

Security

Grade A, and why

rag-development 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 today.

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 installs

The manifest is a name and a version. 1 skill, 1 command, 2 agents travel with it, and installing the plugin installs all of them — 300 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.

rag-development is a plugin published in the GitHub repository acaprino/daodan (8 stars, last pushed yesterday), licensed MIT. Its token cost is not measured: this kind of file is read by the harness, not the model. 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 2026-09-05.
