o9k-new-rule — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited o9k-new-rule (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

First recorded scan — no prior version to compare against.
The primary manifest — the file an agent reads to learn what this artifact does.
R-prefix entries are surfaced in the session-start Rules listing for every session. A project-specific rule written as an R-entry leaks into other projects' context. A cross-project rule buried inside one project never surfaces when working on another. Same content, very different consequence — scope decides.
Ask the user, unless they already said:
"Gilt die Regel projektübergreifend (alle Projekte) oder nur für das aktive Projekt?"
Suggest a default from these heuristics:
| Signal | Likely scope |
|---|---|
| Rule names a specific repo path, file, CLI tool, schema field, project's tech stack | Project-specific |
| Rule mentions hmem code, propagation to end users, project structure | Project-specific (P0048-specific) |
| Rule is about agent behavior, communication style, write protocols, MCP interaction | Cross-project (R) |
| Rule references infrastructure used in many projects (e.g. Strato server, npm publish in general) | Cross-project (R) |
| Rule applies only when one specific project is active | Project-specific |
When in doubt, ask. Wrong scope is the most common failure mode of this workflow.

title="<short imperative title>",

tags=["#hmem", "#<topic-tag>"],

)links may include a project ID for context, but the rule still applies broadly.pinned=true only when the rule belongs in the always-visible Rules block at session start (after the v6.x hook trim, only pinned/favorite R-entries surface). Use sparingly — pinning everything defeats the purpose.First check whether the active project has a Rules section:
read_memory(id="P00XX") # look for an L2 child titled "Rules"If a Rules L2 exists (e.g. P0048.16):
append_memory(
id="P0048.16",
title="<short imperative title>",
body="<full rule text>"
)If no Rules L2 exists, create it with the rule as its first child by leveraging the schema-name exception (root append is allowed when the first line names a section):
append_memory(
id="P00XX",
content="Rules\n\t<short imperative title>\n\n\t<full rule text>"
)Project-specific rules need no tags or links (project-scoped by location) and should never be pinned (visibility is already scoped via the active project).
read_memory(id="<the-new-id>")Confirm title + body are stored correctly. If anything looks off, fix with update_memory immediately.
| Mistake | Why it hurts |
|---|---|
| Writing R-prefix for a one-project rule | Leaks into every other project's session-start Rules block |
| Writing P00XX.Rules.X for a workflow rule that applies to all projects | Invisible whenever a different project is active |
| Pinning a project-specific rule | Already scoped by project; pinning forces it cross-project anyway |
Setting obsolete=true without [✓ID] | Blocked by write protocol — write the correction first |
| Skipping the scope question because "it's obvious" | The previous offender did this and wrote R0028 for a P0048-only rule |
