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.

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 | $0.00076 | $0.01821 |
| Opus 5.5 | $0.00030 | $0.00728 |
| Sonnet 5.5 | $0.00015 | $0.00364 |
| Haiku 4.5 | $0.00008 | $0.00182 |
Grade A, and why
plex scanned grade A with 1 finding 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 1mo 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Plex Media Server Skill
⚠️ MANDATORY SKILL INVOCATION ⚠️
YOU MUST invoke this skill (NOT optional) when the user mentions ANY of these triggers:
- "Plex library", "search Plex", "what's on Plex"
- "Plex sessions", "who's watching", "active streams"
- "browse Plex", "check Plex", "Plex status"
- Any mention of Plex Media Server or querying media
Failure to invoke this skill when triggers occur violates your operational requirements.
Control and query Plex Media Server using the Plex API. Browse libraries, search media, and monitor active sessions.
Purpose
This skill provides read-only access to your Plex Media Server:
- Browse library sections (Movies, TV, Music, Photos)
- Search for specific media
- View recently added content
- Check what's currently playing (active sessions)
- View "On Deck" (continue watching)
- List available clients/players
All operations are GET-only and safe for monitoring/browsing.
Setup
Add your Plex server credentials to ~/.claude-homelab/.env:
# Plex Media Server
PLEX_URL="http://192.168.1.100:32400"
PLEX_TOKEN="<your_plex_token>"
PLEX_URL: Your Plex server URL with port (default: 32400)PLEX_TOKEN: Your Plex authentication token
Getting your Plex token:
- Go to plex.tv → Account → Authorized Devices
- Click on any device, then "View XML"
- Find
X-Plex-Tokenin the URL - Or: Open any media in Plex Web, click "Get Info" → "View XML" and find token in URL
Commands
All commands output JSON. Use jq for formatting or filtering.
The plex-api.sh helper script simplifies API access. Located at: skills/plex/scripts/plex-api.sh
Server Info
# Using helper script
./skills/plex/scripts/plex-api.sh info
# Or raw curl
curl -s "$PLEX_URL/?X-Plex-Token=$PLEX_TOKEN" -H "Accept: application/json"
Browse Libraries
List all library sections:
# Using helper script
./skills/plex/scripts/plex-api.sh libraries
# Or raw curl
curl -s "$PLEX_URL/library/sections?X-Plex-Token=$PLEX_TOKEN" -H "Accept: application/json"
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.

plex is a skill published in the GitHub repository jmagar/claude-homelab (87 stars, last pushed 25d ago), licensed MIT. It adds 76 tokens to every session and 1,821 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls).
