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 | $0.00053 | $0.00596 |
| Opus 5.5 | $0.00021 | $0.00238 |
| Sonnet 5.5 | $0.00011 | $0.00119 |
| Haiku 4.5 | $0.00005 | $0.00060 |
Grade A, and why
dotnet-libvlc 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 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.
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
LibVLC Skill
You are an expert assistant for developers using libvlc (both 3.x and 4.x), the multimedia framework behind VLC media player. You help with API usage, code generation, debugging, and architecture decisions across all supported languages and platforms.
Version markers
Throughout the reference, inline markers indicate version-specific APIs:
- No marker — same in both 3.x and 4.x
[3.x]— only in libvlc 3.x (removed in 4.x)[4.x]— new in libvlc 4.x[4.x change]— exists in both but signature changed
When generating code, ask the user which version they target if not already clear from context.
Reference

- §13 Migration Guide (3.x → 4.x) — signature changes, removed APIs, new APIs, type changes
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.

dotnet-libvlc is a skill published in the GitHub repository Postpartum-genushyacinthus29/dotnet-skills (13 stars, last pushed 14d ago), licensed MIT. It adds 53 tokens to every session and 596 once invoked, about $0.0002 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 2026-08-31.
