Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00106 | $0.02857 |
| Opus 5 | $0.00053 | $0.01429 |
| Sonnet 5 | $0.00021 | $0.00571 |
| Haiku 4.5 | $0.00011 | $0.00286 |
Grade A, and why
adr-author 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 2d 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.
How it starts
The opening of the file, as written. The whole thing — 330 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ADR Authoring Guide
Help users write Architectural Decision Records that future developers actually read and that automated review systems can enforce. Based on Michael Nygard's format from Documenting Architecture Decisions.
How to Think About ADRs
An ADR captures a decision at a moment in time. It answers: what did we decide, why, and what happens because of it? The audience is a future developer (or an AI reviewer) who encounters code that seems odd and needs to understand the reasoning behind it.
The Decision section is the heart of an ADR — it's what gets enforced. The rest (Context, Consequences) provides the reasoning that makes enforcement feel reasonable rather than arbitrary. Spend most of your effort on the Decision section, and write it at the enforceability level the team actually needs.
Workflow
Step 1: Read Existing ADRs
Before writing anything, find and read the project's existing ADRs. They're
typically in docs/adr/, doc/arch/, or decisions/. Look for:
- Numbering scheme (sequential integers, date-prefixed, etc.)
- Section structure (some teams add "Alternatives Considered" or "References")
- Tone and detail level
- Status conventions
Match what's already there. Consistency matters more than any template.
Step 2: Understand the Decision
Ask the user (if not already clear from context):
- What's the decision? What architectural choice is being made?
- What's the problem? What forces or tensions led here?
- What alternatives were considered? Even briefly — this goes in Context.
- How should this be enforced? This determines enforceability level.
The fourth question is the key one this skill adds. Most ADR guides skip it, but it determines whether the ADR becomes a living contract or shelf-ware.
Step 3: Choose an Enforceability Level
Enforceability isn't about quality — a LOW enforceability ADR can be excellent. It's about what kind of verification is possible and appropriate.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-author is a skill published in the GitHub repository delexw/claude-code-misc (1 stars, last pushed 5mo ago), licensed MIT. It adds 106 tokens to every session and 2,857 once invoked, about $0.0005 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.
