adr

adr is a skill for Claude Code, Codex from DavidROliverBA/ArchitectKB. It costs 0 tokens per session (2,599 once invoked), scanned A, original, MIT.

A command for creating an Architecture Decision Record, a document that explains an important technical choice and why it was made. It follows an organisation's defined ADR process.

In plain words
What is it for?
Use it to create a new ADR, optionally attach it to a project, search for relevant organisational decisions, and show which existing decisions may constrain the choice.
Why use it?
It helps teams check existing decisions before making a new one, reducing conflicts and keeping technical reasoning recorded.

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.

/adr

Create a new Architecture Decision Record (ADR) following the official YourOrg ADR process.

Usage

/adr <title>
/adr <title> for <project>

Examples

/adr API Gateway Selection
/adr Kafka vs EventBridge for Project - MyDataIntegration
/adr Standalone Laptop for Offline Database Build

Instructions

1. Parse Command and Initial Setup

Parse the command for:

  • title: The ADR name (required)
  • project: Related project (optional)

2. Discover Relevant Organisational ADRs

IMPORTANT: Before creating a new ADR, search for existing organisational ADRs that may constrain or inform this decision.

Search the vault for relevant ADRs:

  1. Search +Sync/Org-ADRs/ for ADRs with authority: organizational
  2. Search vault root for ADRs with status: accepted
  3. Look for keywords matching the decision topic

Display found ADRs to the user:

📋 Relevant Organisational ADRs Found:

**Must Follow** (authority: organizational):
- [[ADR - API Gateway Selection]] - Mandates Kong for API management
- [[ADR - Cloud Provider Selection]] - Requires AWS for new services

**Consider** (authority: team, related domain):
- [[ADR - Kafka Event Patterns]] - Event-driven patterns for integration
- [[ADR - Data Product Standards]] - Data exchange formats

Would you like to reference any of these in your new ADR's `dependsOn` field?

Store selected references for later inclusion in frontmatter.

3. Check for Existing Guardrail

CRITICAL STEP: Before creating an ADR, check if a relevant guardrail already exists.

Ask the user:

"Before creating this ADR, have you checked if there's an existing guardrail that covers this decision? If a guardrail exists, you should follow it instead of creating an ADR."

If user confirms no guardrail exists, proceed to step 4.

4. Determine ADR Type

Ask the user to select the ADR type (explain each):

Question: "What type of ADR is this?"

Options:

  1. Technology_ADR - New technology/tool or significant change to existing technology
    • Examples: New database, cloud service, development tool, infrastructure component
    • Requires SME approvals for the specific technology area

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.
