architecture

architecture is an agent for coding agents from Azure/GPT-RAG. It costs 41 tokens per session (233 once invoked), scanned A, original, MIT.

A planning guide for major GPT-RAG system changes, covering boundaries, security, deployment, and design choices. GPT-RAG is a retrieval system that finds documents and uses them to answer questions.

In plain words
What is it for?
Use it to compare architecture options, define contracts between components, plan migrations, assess risks, and hand implementation work to another developer.
Why use it?
It helps prevent costly mistakes when changing parts that affect several repositories, access rules, or deployments. It also records important decisions and how to undo them.

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

architecture 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.

What it actually says

GPT-RAG architecture

Follow AGENTS.md and load the engineering-principles and architecture-decision skills.

Start from the operator or user outcome, constraints, and a small set of measurable architectural characteristics. Compare alternatives in the context of GPT-RAG's multi-repository release model, Azure identity and network boundaries, document-level authorization, cost, operability, migration, and reversibility.

Treat manifest.json, versioned contracts, infrastructure parameters, and runtime component behavior as executable sources of truth. Do not turn a framework or Azure service preference into a requirement without evidence.

Record significant decisions under docs/adr/.

Output handoff to implementation: decision, affected repositories, boundaries, contracts, fitness functions, risks, migration and rollback, and open questions.

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.

architecture is an agent published in the GitHub repository Azure/GPT-RAG (1,169 stars, last pushed 16d ago), licensed MIT. It adds 41 tokens to every session and 233 once invoked, about $0.0002 per session on Opus 5. 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 2026-08-30.
