architecture-decision

architecture-decision is a skill for Claude Code, Codex from Azure/GPT-RAG. It costs 42 tokens per session (209 once invoked), scanned A, original, MIT.

A recorded architecture decision for GPT-RAG systems. It compares technical options when a choice affects system boundaries, data, identity, deployment, or other costly-to-reverse parts of the design.

In plain words
What is it for?
Use it to create an architecture decision record, compare viable alternatives, define success measures and review triggers, and plan adoption and rollback.
Why use it?
It makes important design choices verifiable by documenting constraints, alternatives, trade-offs, measures, migration, and rollback. This helps teams avoid treating a personal tool preference as a required architecture.

About the project

GPT-RAG is an Azure solution accelerator for building agentic retrieval-augmented generation systems, where agents use connected organizational sources to ground their answers. It is for organizations deploying secure RAG applications with Microsoft Foundry, Microsoft Agent Framework, and Azure infrastructure. The catalogue add-ons provide agents, skills, and instructions for deploying and working with the accelerator.

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-decision 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 9d 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 architectural decision

  1. Load the relevant engineering-principles references.
  2. Define context, constraints, affected repositories, and up to five prioritized characteristics with measures.
  3. Compare at least two viable alternatives and the option of not changing.
  4. Evaluate identity, authorization, network isolation, component compatibility, cost, operation, migration, and reversibility.
  5. Record the decision under docs/adr/ using the ADR template.
  6. Define fitness functions, adoption order, rollback or roll-forward, and a review trigger.

Do not turn a tool or framework preference into an architectural requirement. When evidence is missing, record a time-bounded investigation and its decision criterion instead of guessing.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
