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 medium
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 29 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.
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 | $0.00077 | $0.01375 |
| Opus 5 | $0.00039 | $0.00687 |
| Sonnet 5 | $0.00015 | $0.00275 |
| Haiku 4.5 | $0.00008 | $0.00137 |
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.
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

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, runconfigcommand 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
What ships with it
6 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.
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.
