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 5.1 | $0.00089 | $0.03803 |
| Opus 5 | $0.00044 | $0.01902 |
| Sonnet 5 | $0.00018 | $0.00761 |
| Haiku 4.5 | $0.00009 | $0.00380 |
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.
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.
This is a copy
100% identical to adr-skill — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

ADR Skill
Philosophy
ADRs created with this skill are executable specifications for coding agents. A human approves the decision; an agent implements it. The ADR must contain everything the agent needs to write correct code without asking follow-up questions.
This means:
- Constraints must be explicit and measurable, not vibes
- Decisions must be specific enough to act on ("use PostgreSQL 16 with pgvector" not "use a database")
- Consequences must map to concrete follow-up tasks
- Non-goals must be stated to prevent scope creep
- The ADR must be self-contained — no tribal knowledge assumptions
- The ADR must include an implementation plan — which files to touch, which patterns to follow, which tests to write, and how to verify the decision was implemented correctly
When to Write an ADR
Write an ADR when a decision:
- Changes how the system is built or operated (new dependency, architecture pattern, infrastructure choice, API design)
- Is hard to reverse once code is written against it
- Affects other people or agents who will work in this codebase later
- Has real alternatives that were considered and rejected
Do NOT write an ADR for:
- Routine implementation choices within an established pattern
- Bug fixes or typo corrections
- Decisions already captured in an existing ADR (update it instead)
- Style preferences already covered by linters or formatters
When in doubt: if a future agent working in this codebase would benefit from knowing why this choice was made, write the ADR.
Proactive ADR Triggers (For Agents)
If you are an agent coding in a repo and you encounter any of these situations, stop and propose an ADR before continuing:
- You are about to introduce a new dependency that doesn't already exist in the project
- You are about to create a new architectural pattern (new way of handling errors, new data access layer, new API convention) that other code will need to follow
- You are about to make a choice between two or more real alternatives and the tradeoffs are non-obvious
- You are about to change something that contradicts an existing accepted ADR
- You realize you're writing a long code comment explaining "why" — that reasoning belongs in an ADR
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-skill is a skill published in the GitHub repository Agent-Threat-Rule/agent-threat-rules (389 stars, last pushed today), licensed MIT. It adds 89 tokens to every session and 3,803 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to adr-skill, differing in 0 lines, and is treated as a copy.
