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 | $0.00066 | $0.02983 |
| Opus 5 | $0.00033 | $0.01491 |
| Sonnet 5 | $0.00013 | $0.00597 |
| Haiku 4.5 | $0.00007 | $0.00298 |
Grade A, and why
youtube-devrel 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 5d 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 — 417 lines — stays where its author put it; the contents beside it link to each section on GitHub.
YouTube for Developer Relations
YouTube is the second-largest search engine and where developers go to learn. This skill covers tutorial structure, screen recording setup, live coding, shorts vs long-form, thumbnails, and SEO for technical content.
Before You Start
- Read
.agents/developer-audience-context.mdif it exists - Audit existing technical YouTube channels in your space
- Understand: Developer YouTube is a long game — consistency > perfection
Understanding Developer YouTube
Who Watches Dev Content
| Audience | What they want | Video length |
|---|---|---|
| Learning developers | Complete tutorials | 15-45 min |
| Working developers | Quick solutions | 5-15 min |
| Senior developers | Deep dives, architecture | 30-60 min |
| Decision makers | Demos, overviews | 3-10 min |
| Conference attendees | Recorded talks | 20-45 min |
Content Types That Work
| Content type | View potential | Effort | Notes |
|---|---|---|---|
| Tutorial (build X) | Very high | High | Evergreen traffic |
| Problem/solution | High | Medium | Search-driven |
| Tool comparisons | High | Medium | High search volume |
| Live coding | Medium-high | Low | Engagement-focused |
| Project updates | Medium | Low | Community building |
| Conference talks | Medium | Low | Repurpose content |
| Shorts | High reach | Low | Discovery-focused |
Successful Dev YouTube Channels
| Channel | Style | Why it works |
|---|---|---|

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.
