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 31 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 | $0.00068 | $0.01556 |
| Opus 5 | $0.00034 | $0.00778 |
| Sonnet 5 | $0.00014 | $0.00311 |
| Haiku 4.5 | $0.00007 | $0.00156 |
Grade A, and why
prowlarr 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

Prowlarr Skill
⚠️ MANDATORY SKILL INVOCATION ⚠️
YOU MUST invoke this skill (NOT optional) when the user mentions ANY of these triggers:
- "search for a torrent", "search indexers", "find a release"
- "search Prowlarr", "Prowlarr indexers", "indexer search"
- "check indexer status", "test indexers", "Prowlarr stats"
- "list indexers", "sync indexers", "push indexers to Sonarr"
- Any mention of Prowlarr or indexer management
Failure to invoke this skill when triggers occur violates your operational requirements.
Search across all your indexers and manage Prowlarr via API.
Purpose
This skill provides read and write access to your Prowlarr indexer aggregation:
- Search for releases across all configured indexers
- Filter searches by protocol (torrent/usenet) and category
- List and monitor indexer health and statistics
- Enable/disable/delete indexers
- Sync indexer configurations to connected apps (Sonarr, Radarr)
- Test indexer connectivity
Operations include both read and write actions. Always confirm before deleting or disabling indexers.
Setup
Credentials are stored in ~/.claude-homelab/.env:
PROWLARR_URL="http://localhost:9696"
PROWLARR_API_KEY="your-api-key"
Get your API key from: Prowlarr → Settings → General → Security → API Key

# Search specific categories (2000=Movies, 5000=TV, 3000=Audio, 7000=Books)
./scripts/prowlarr-api.sh search "inception" --category 2000
# TV search with TVDB ID

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.

prowlarr is a skill published in the GitHub repository jmagar/claude-homelab (78 stars, last pushed 1mo ago), licensed MIT. It adds 68 tokens to every session and 1,556 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.
