adr-skill

adr-skill is a skill for Claude Code, Codex from joelhooks/joelclaw. It costs 89 tokens per session (5,221 once invoked), scanned A, original, no licence file.

A workflow for recording important software architecture decisions in Architecture Decision Records (ADRs), short documents that explain what was decided and why.

In plain words
What is it for?
Use it to create, update, approve, reject, retire, or replace ADRs, set up an ADR folder and index, and check earlier decisions before changing code.
Why use it?
It keeps decisions available to coding agents and developers instead of leaving them scattered in conversations or forgotten after implementation.

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-skill 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 6d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/bootstrap_adr.js, scripts/new_adr.js, scripts/set_adr_status.js), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 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.
