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.

SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Memory Poisoning · line 3 Skill manipulates agent memory, state, or stored context. Memory corruption can alter personality, override safety rules, or cause unpredictable behavior.Fix: Protect agent memory and state from modification by untrusted content. Use read-only memory for critical instructions and validate all state changes.
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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00067 | $0.01649 |
| Opus 5 | $0.00034 | $0.00825 |
| Sonnet 5 | $0.00013 | $0.00330 |
| Haiku 4.5 | $0.00007 | $0.00165 |
Grade A, and why
adr-authoring 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.
How it starts
The opening of the file, as written. The whole thing — 109 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ADR Authoring
Architecture Decision Records for capturing design rationale. ADRs supply the temporal dimension — decisions over time — that structure-only views (C4) miss.
Start with Repository Conventions
- Read the repository's agent instructions, contributing guide, ADR index, template, and a few recent records before drafting. Reuse the established location, numbering, headings, status vocabulary, approval process, and amendment policy.
- Treat this skill's layouts and templates as fallbacks only. Do not move, renumber, rename, or rewrite existing ADRs to fit the skill. If local conventions conflict, preserve the existing records and identify the specific conflict before changing the convention.
- If no convention exists, use a flat
docs/adr/directory, stable sequential identifiers, a small index, and a lightweight Nygard template (MADR when option analysis needs more structure). Readreferences/project-setup-guide.mdonly when establishing a new decision log. - Read
references/adr-to-pyramid-mapping.mdonly if the project already uses artifact pyramids or the user requests that organization. Index links can provide layered navigation without relocating canonical records.
Decision, Approval, and Evidence
Keep these three facts distinct, using the repository's existing fields or linked records:
- Proposal: What is recommended, why, alternatives, consequences, and unresolved questions. A draft or recommendation is not an accepted decision.
- Decision authority and scope: Who approved what, when, and for which environment or stage. Approval to experiment permits the bounded experiment; it does not establish production adoption. An accepted ADR may authorize only an experiment if that scope is explicit. Do not invent a decider, date, or broader approval.
- Implementation evidence: Links to changes, checks, observed results, and remaining gaps. Acceptance does not prove implementation; passing a prototype check does not prove production readiness. Label a validation plan as planned until results exist.

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-authoring is a skill published in the GitHub repository magnus919/agent-skills (76 stars, last pushed today), licensed MIT. It adds 67 tokens to every session and 1,649 once invoked, about $0.0003 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 2026-08-30.
