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.

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 | $0.00000 | $0.00274 |
| Opus 5.5 | $0.00000 | $0.00110 |
| Sonnet 5.5 | $0.00000 | $0.00055 |
| Haiku 4.5 | $0.00000 | $0.00027 |
Grade A, and why
50-rag-system 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 1mo 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.
What it actually says
RAG architecture:
- Separate ingestion, parsing, chunking, embedding, indexing, retrieval, reranking, context assembly, and answer generation.
- Keep retrieval logic independent from answer generation logic.
- Preserve source metadata for traceability.
RAG rules:
- Never dump raw full documents into prompts when chunking is expected.
- Use deterministic chunking strategies unless explicitly experimenting.
- Maintain chunk metadata such as source, page, section, title, tenant, and timestamps where relevant.
- Prefer source attribution/citations in outputs when the product requires trust and traceability.
- Add configurable retrieval parameters such as top_k, filters, score thresholds, and reranking options.
Ingestion expectations:
- Support clean document ingestion pipelines.
- Normalize and sanitize extracted text.
- Preserve source identity and version if relevant.
- Re-embed only when necessary.
Answering expectations:
- Ground answers in retrieved context.
- Handle no-context and low-confidence cases gracefully.
- Avoid hallucinating unavailable facts.
- Return structured outputs where the product requires it.
Do not:
- Mix ingestion code with runtime answer generation in the same module.
- Make retrieval behavior impossible to inspect or tune.
- Hide retrieval failures silently.
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.

50-rag-system is a cursor rule published in the GitHub repository aiagentwithdhruv/ai-dev-stack (11 stars, last pushed 3mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 274 tokens. 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.
