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 | $0.00101 | $0.05622 |
| Opus 5 | $0.00051 | $0.02811 |
| Sonnet 5 | $0.00020 | $0.01124 |
| Haiku 4.5 | $0.00010 | $0.00562 |
Grade C, and why
finding-original-cds scanned grade C with 2 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.

Finding original CDs on Discogs
Overview
Pick the best original or non-remastered CD pressing of an album and add it to the wantlist, balancing how common a pressing is (haves), price, and US availability. Core insight: have/want counts live in the public Discogs release API (WebFetch https://api.discogs.com/releases/<id>, no auth) — the discogs MCP tools cannot return them — and the live price lives in a second call, /marketplace/stats/<id>. That's the step that gets re-derived every session; don't.
Default target is a US CD unless the user says otherwise.
When to use
- "Find an original / non-remastered CD of [album]" · "add the original pressing to my wantlist"
- "Which [album] CD should I get / buy?" · comparing pressings · avoiding remaster/deluxe/anniversary editions
Not for: vinyl-specific hunts (same method, swap the format filter), buying/checkout, or non-Discogs catalogs.
Tool reality — what returns what
| Need | Tool | Returns | Missing |
|---|---|---|---|
| List pressings | search_discogs(type="release") |
format, label, year, ID | country, have/want |
| Pressing details | get_release(<id>) (MCP) |
country, catalog #, format, tracklist | have/want, price |
| Have/want + stock | WebFetch https://api.discogs.com/releases/<id> |
community.have/want, num_for_sale, country, year, catalog |
a trustworthy price — see below |
| The price you quote | curl "https://api.discogs.com/marketplace/stats/<id>?curr_abbr=USD" |
live {num_for_sale, lowest_price, blocked_from_sale} |
— (the only current figure) |
| Which master is on the disc | same call → identifiers[] (type == "Matrix / Runout") + notes |
matrix runout, SID codes, pressing-plant IDs, manufacturing-window notes | — (the only hard evidence; see matrix section) |
| Cover/case photos | curl api.discogs.com/releases/<id> → images[].uri, then download + Read |
public image URLs (no auth), then view the JPEGs | discogs.com website blocks WebFetch (403); the API doesn't |
| Add | add_to_wantlist(release_id) |
confirmation | takes release_id only |
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.

finding-original-cds is a skill published in the GitHub repository rianvdm/product-ai-public (16 stars, last pushed 2d ago), licensed MIT. It adds 101 tokens to every session and 5,622 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
