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 | $0.00111 | $0.02435 |
| Opus 5 | $0.00056 | $0.01218 |
| Sonnet 5 | $0.00022 | $0.00487 |
| Haiku 4.5 | $0.00011 | $0.00244 |
Grade B, and why
hifi-download scanned grade B 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 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
| `PYTHON=missing` | `brew install python3` | `sudo apt install python3` | How it starts
The opening of the file, as written. The whole thing — 273 lines — stays where its author put it; the contents beside it link to each section on GitHub.
MusicMaster
Music discovery (Spotify, Last.fm) and Hi-Res audio downloads (Qobuz, TIDAL) through a unified CLI.
Language
Match user's language: Respond in the same language the user uses.
All commands use bash ${SKILL_PATH}/run.sh <script> [args...], which activates the venv and runs the corresponding Python script. Output is human-readable by default; use --json where supported for structured output.
First-Time Setup
Step 1: Check Dependencies
bash ${SKILL_PATH}/scripts/setup.sh check
Output is key=value pairs. If VENV=missing, run install first.
Step 2: Install
bash ${SKILL_PATH}/scripts/setup.sh install [--with-qobuz] [--with-tidal]
Creates .venv, installs core dependencies (spotipy, pylast, requests, python-dotenv), and optionally installs download backends.
Step 3: Configure Credentials
IMPORTANT: Do NOT ask the user for credentials in chat. Instead:
- Create
.envfrom template if not exists:cp ${SKILL_PATH}/.env.example ${SKILL_PATH}/.env - Tell user to edit
${SKILL_PATH}/.envwith their credentials - Wait for confirmation, then verify with Step 4
Where to get credentials:
- Spotify: https://developer.spotify.com/dashboard (free)
- Last.fm: https://www.last.fm/api/account/create (free)
- Qobuz: Requires Studio/Sublime subscription
- TIDAL: Run
tiddl auth loginin venv for OAuth (no.enventry needed)
Step 4: Verify
bash ${SKILL_PATH}/run.sh status
Shows which services are READY, DISABLED, or need setup. Only use services marked READY.
Preflight Check → Fix Table

| TIDAL: NOT CONFIGURED | Run tiddl auth login inside the venv |
Same |
| Spotify/Last.fm/Qobuz: ERROR (validation failed) | Check credentials in .env are correct, re-obtain from dashboard if needed |
Same |
| TIDAL: ERROR (token expired) | Run tiddl auth refresh or tiddl auth login inside the venv |

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.

hifi-download is a skill published in the GitHub repository psylch/media-master (5 stars, last pushed 6mo ago), licensed MIT.
