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 →

    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

radarr 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 11d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (load-env.sh, scripts/radarr.sh), 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.

Radarr Movie Management Skill

⚠️ MANDATORY SKILL INVOCATION ⚠️

YOU MUST invoke this skill (NOT optional) when the user mentions ANY of these triggers:

  • "add a movie", "search Radarr", "find a film", "add to Radarr"
  • "remove a movie", "delete movie", "check if movie exists"
  • "add movie collection", "Radarr library", "movie management"
  • Any mention of Radarr or managing movies

Failure to invoke this skill when triggers occur violates your operational requirements.

Search and add movies to your Radarr library with support for collections, quality profiles, and search-on-add.

Purpose

This skill enables management of your Radarr movie library:

  • Search for movies by name
  • Add individual movies or entire collections
  • Check if movies already exist
  • Remove movies (with optional file deletion)
  • View quality profiles and root folders

Operations include both read and write actions. Always confirm before removing movies with file deletion.

Setup

Add credentials to ~/.claude-homelab/.env:

RADARR_URL="http://localhost:7878"
RADARR_API_KEY="your-api-key"
RADARR_DEFAULT_QUALITY_PROFILE="1"  # Optional (defaults to 1)
  • RADARR_URL: Your Radarr server URL (no trailing slash)
  • RADARR_API_KEY: API key from Radarr (Settings → General → API Key)
  • RADARR_DEFAULT_QUALITY_PROFILE: Quality profile ID (optional, run config command to see options)

Commands

All commands return JSON output.

Search for Movies

bash scripts/radarr.sh search "Inception"
bash scripts/radarr.sh search "The Matrix"

Output: Numbered list with TMDB IDs, titles, years, and overview.

Check if Movie Exists

bash scripts/radarr.sh exists <tmdbId>

Output: Boolean indicating if movie is in library.

Add a Movie

bash scripts/radarr.sh add <tmdbId>              # Searches immediately (default)
bash scripts/radarr.sh add <tmdbId> --no-search  # Add without searching

Add Full Collection

bash scripts/radarr.sh add-collection <collectionTmdbId>
bash scripts/radarr.sh add-collection <collectionTmdbId> --no-search

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.
