adr-methodology

adr-methodology is a skill for Claude Code from basher83/lunar-claude. It costs 30 tokens per session (1,101 once invoked), scanned A, original, MIT.

A structured method for documenting architecture decisions with templates, comparison tables, risk ratings, and human review. It uses MADR, a format for writing Architecture Decision Records.

In plain words
What is it for?
It helps generate assessment criteria, evaluate options, summarize trade-offs, and format decision records while keeping final accountability with people.
Why use it?
It makes technical decisions easier to compare and revisit by recording the context, criteria, alternatives, risks, and final reasoning.

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-methodology 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 Methodology

Structured frameworks for documenting architectural decisions with human-in-the-loop AI assistance.

Core Principle

AI handles drafting, formatting, and enumeration. Humans provide project-specific context, stakeholder awareness, and final decision accountability.

AI assists with:

  • Research and enumeration of options
  • Consistent formatting
  • Risk/trade-off summarization
  • Matrix generation

Humans provide:

  • Project-specific context and constraints
  • Stakeholder empathy and political nuance
  • Final decision accountability

Workflow Stages

Stage 1: Context to Criteria (/adr-assistant:new)

Gather decision context and generate assessment criteria.

  1. Ask for problem description, constraints, stakeholders, initial options
  2. Select appropriate framework (Salesforce Well-Architected or Technical Trade-off)
  3. Generate criteria grouped by framework pillars
  4. For each criterion: name, rationale for this decision, definition of "good"
  5. Write criteria to .claude/adr-session.yaml
  6. Prompt user to refine criteria before analysis

Stage 2: Options Matrix (/adr-assistant:analyze)

Evaluate options against criteria with risk ratings.

  1. Read criteria from .claude/adr-session.yaml
  2. For each option, rate against each criterion (Low/Medium/High risk)
  3. Include rationale for each rating
  4. Generate comparison matrix table
  5. Write analysis to state file
  6. Prompt user to refine ratings before generation

Stage 3: ADR Generation (/adr-assistant:generate)

Output final ADR document using MADR template.

  1. Read criteria and analysis from state file
  2. Ask user which option they're choosing and why
  3. Generate ADR with AI disclosure
  4. Auto-detect next ADR number from docs/adr/
  5. Write ADR file
  6. Clear state file

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.
