adr

adr is a skill for Claude Code, Codex from 0xrafasec/ai-workflow. It costs 75 tokens per session (652 once invoked), scanned A, original, MIT.

A guided workflow for writing an Architecture Decision Record, a short numbered document that preserves one important technical choice and why it was made.

In plain words
What is it for?
Use it to record the context, alternatives, chosen option, reasons, and accepted consequences of a technical decision.
Why use it?
It prevents the reasoning behind design decisions from being lost when the team or code changes later.

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

adr 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 5d 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.

Create an Architecture Decision Record. Argument: $ARGUMENTS

Context

ADRs capture a single decision — the context, options considered, and the choice made. They're lightweight and accumulate over time. Each ADR is a separate numbered file.

Context Gathering

  1. Check docs/adr/ for existing ADRs — determine the next number. If no ADRs exist, start at 0001.
  2. Read recent ADRs (last 2-3) to match the project's style and voice.
  3. If the decision relates to architecture, read docs/ARCHITECTURE.md for context.

Interview

Use AskUserQuestion to extract the decision. Keep it focused — an ADR is one decision, not a design doc.

  1. What's the decision? — What are you deciding? What triggered this decision?
  2. Context — What constraints, requirements, or pressures led to this? What's the current state?
  3. Options considered — What alternatives did you evaluate? What are the tradeoffs of each?
  4. Decision — What did you choose and why? What was the deciding factor?
  5. Consequences — What changes as a result? What are the known downsides you're accepting?

If the decision is straightforward (user already knows what they want and why), keep the interview to 1-2 questions to fill in gaps.

Write

- **Cons:** [drawbacks]

### Option B: [Name]

## Consequences

### Positive
- [What improves]

### Negative

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.
