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.

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 | $0.00037 | $0.00501 |
| Opus 5 | $0.00018 | $0.00251 |
| Sonnet 5 | $0.00007 | $0.00100 |
| Haiku 4.5 | $0.00004 | $0.00050 |
Grade A, and why
mood-music 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 8d 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.
What it actually says
Mood Music
Instructions
You MUST use a strict two-step process to generate music. This ensures you only request musical genres that are currently supported by the Loudly API.
Step 1: Fetch Available Genres
Call the run_js tool with get_genres.html as the script name and an empty JSON payload ({}).
- This will return a list of currently available genres and their descriptions.
- You MUST review this list to understand the available musical palettes.
Step 2: Analyze and Generate
Once you have the valid genres, map the user's request to the best fit and call run_js with index.html to generate the track.
Handling Inputs:
- Text Inputs: Translate abstract mood requests into a concrete, matching genre from the fetched list, along with an appropriate energy level.
- Media Inputs (Images/Audio): If the user provides an image or audio clip, analyze the media to determine its underlying mood, atmosphere, or vibe. Translate this analysis strictly into one of the fetched genres.
Generation Payload (for index.html):
Your JSON payload for index.html MUST strictly use these text fields to represent the vibe:
- genre: String, Required. MUST be an exact match to a genre name retrieved in Step 1.
- genre_blend: String, Optional. A secondary genre to blend (also from Step 1).
- duration: Integer, Optional. Length in seconds (30-420). Default is 120.
- energy: String, Optional. Vibe ("low", "high", "original").
- bpm: Integer, Optional. Specific tempo in Beats Per Minute.
Invocation Triggers
You should invoke this skill when the user:
- Asks for music for a specific mood.
- Asks for playlist ideas for a vibe.
- Uploads an image or audio clip and asks for music to match it.
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.

mood-music is a skill published in the GitHub repository StrinGhost/gemma-skills (54 stars, last pushed 5mo ago), licensed Apache-2.0. It adds 37 tokens to every session and 501 once invoked, about $0.0002 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.
