In plain words
What is it for?

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 →

  • medium Rogue Agent · line 3
    Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
    Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

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

learning-vault 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.

The scan reads SKILL.md. This mod also ships 1 executable file (dataview-plugin/main.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.

Learning Vault Generator

Create a fully structured Obsidian vault for any learning goal — certification exams, courses, skill acquisition, or research programs.

Trigger Phrases

  • "create a learning vault for X"
  • "build a study vault"
  • "set up a certification vault"
  • "learning vault for [topic]"
  • "/learning-vault"

Interactive Setup

Ask the user these questions (use AskUserQuestion):

1. Subject & Goal

  • What is the learning goal? (certification, course, skill, research)
  • What is the subject? (e.g., "AWS Solutions Architect", "Rust programming", "Machine Learning")
  • Is there a specific exam or assessment? If yes, get: format, passing score, domains/topics, timeline

2. Structure

  • How many main topics/domains? (auto-detect from curriculum if URL provided)
  • Are there courses to track? (get URLs, lesson counts)
  • Are there scenarios/practice areas?

3. Self-Assessment

  • For each domain/topic, ask: "How confident are you?" (expert/strong/moderate/needs-work/no-experience)
  • This drives the study priority ordering

4. Configuration

  • Vault location (default: ~/Brains/{subject-slug}/)
  • Daily notes? (yes/no)
  • Dataview plugin assumed? (yes — required for queries)

What ships with it

4 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.

Changes

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.
