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 | $0.00074 | $0.01174 |
| Opus 5.5 | $0.00030 | $0.00470 |
| Sonnet 5.5 | $0.00015 | $0.00235 |
| Haiku 4.5 | $0.00007 | $0.00117 |
Grade A, and why
soundcloud-api-sync 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 4d 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
The opening of the file, as written. The whole thing — 87 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SoundCloud API sync
SoundCloud ships API changes with no email list and no versioning. The GitHub release notes are the only real changelog, and endpoints have been removed from the public API without deprecation — they just start returning 405. This skill re-derives what is true from the official sources.
Run the audit first
node .claude/skills/soundcloud-api-sync/audit.mjs # latest 8 releases
node .claude/skills/soundcloud-api-sync/audit.mjs --since 2026-10-28
It fetches the live spec and prints three things:
- NOT IMPLEMENTED — spec operations no tool calls yet, method-aware
(
POST /trackscounts as missing even though weGET /tracks). - CALLED BUT NOT IN SPEC — the dangerous direction. Anything listed here is a candidate for the silent 405 treatment; verify it live before trusting it.
- RELEASES — dated release-note headlines.
Synced through: 2026-10-28.
Pass --since with that date to see only what is new, then update it here when
done. The coverage gap list lives in
issue #2.
Authoritative sources, in order
| Source | URL | Use for |
|---|---|---|
| OpenAPI spec (YAML) | https://raw.githubusercontent.com/soundcloud/api/master/openapi/api.yaml |
The contract. Check before adding any endpoint. |
| Release notes | https://github.com/soundcloud/api/releases | The changelog. Nothing else lists changes. |
| Spec commit history | https://github.com/soundcloud/api/commits/master/openapi/api.yaml | Diffs between releases; chore: update OpenAPI spec commits land ahead of some notes. |

What ships with it
1 file 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.

soundcloud-api-sync is a skill published in the GitHub repository jamiew/soundcloud-mcp (1 stars, last pushed 5d ago), licensed MIT. It adds 74 tokens to every session and 1,174 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-09-01.
