adr

adr is a skill for Claude Code from rvdbreemen/adr-kit. It costs 19 tokens per session (312 once invoked), scanned A, original, MIT.

A skill for creating or reviewing Architecture Decision Records (ADRs), documents that record important technical choices and their reasoning.

In plain words
What is it for?
Use it to find related accepted decisions, create proposed ADRs, review alternatives and consequences, and formally accept or replace decisions.
Why use it?
It helps determine whether a decision is significant enough to document and checks that the record is complete, supported by evidence, and consistent with earlier decisions.

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.

What it actually says

ADR authoring

Invoke explicitly with $adr-kit:adr when needed. Resolve <plugin-root> from this installed skill. Use only bundled, local ADR Kit tools and follow this canonical workflow:

  1. Query the generated ADR index for relevant Accepted ADRs before writing, open only returned sources, and report conflicts.
  2. Run python <plugin-root>/bin/adr profiles --format json; use only a returned profile with available: true.
  3. Use madr as the default; support nygard and canonical only when returned as available, and never invent a profile or template.
  4. Qualify <subject> as a consequential, difficult-to-reverse decision before creating a record; do not create an ADR for an ordinary reversible implementation choice.
  5. Create a Proposed record, then follow the canonical grill protocol for context, decision, alternatives, consequences, risks, mitigations, evidence, scope, ownership, conflicts, and Open Questions.
  6. Show the final acceptance packet and require an explicit yes in this active session before invoking adr accept ... --confirm; require Completeness, Evidence, Clarity, and Consistency and supersede rather than rewriting Accepted decisions.

Do not contact another model or mutate user-owned instructions.

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.

adr is a skill published in the GitHub repository rvdbreemen/adr-kit (6 stars, last pushed 9d ago), licensed MIT. It adds 19 tokens to every session and 312 once invoked, about $0.0001 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 2026-08-31.
