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.

What it costs to keep this loaded
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 | $0.00020 | $0.00327 |
| Opus 5.5 | $0.00008 | $0.00131 |
| Sonnet 5.5 | $0.00004 | $0.00065 |
| Haiku 4.5 | $0.00002 | $0.00033 |
Grade A, and why
yt-dlp scanned grade A 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 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.

What it actually says
yt-dlp
Download YouTube videos, audio, and subtitles/transcripts.
Setup
Check if yt-dlp is installed, and download it if not:
if ! command -v yt-dlp &>/dev/null && [ ! -f ~/yt-dlp ]; then
curl -sL https://github.com/yt-dlp/yt-dlp/releases/latest/download/yt-dlp -o ~/yt-dlp && chmod +x ~/yt-dlp
fi
Then use ~/yt-dlp (or just yt-dlp if installed globally).
Examples
Download subtitles/transcript:
~/yt-dlp --write-auto-sub --sub-lang en --skip-download -o "/tmp/%(id)s" <url>
Download audio only:
~/yt-dlp -x --audio-format mp3 -o "/tmp/%(title)s.%(ext)s" <url>
Download video:
~/yt-dlp -o "/tmp/%(title)s.%(ext)s" <url>
Get video info (title, duration, description):
~/yt-dlp --print title --print duration_string --print description --no-download <url>
Notes
- Subtitles are saved as
.vttfiles - read them to get the transcript - Use
/tmp/for downloads to avoid cluttering the working directory
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.

yt-dlp is a skill published in the GitHub repository ykdojo/safeclaw (186 stars, last pushed 28d ago), licensed MIT. It adds 20 tokens to every session and 327 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

start
Use this skill when the user runs /start, says "start", "enable the SDLC workflow", "I want to build", "I want to fix", "set up", "get started", or otherwise signals they want to activate or re-enable the SDLC workflow. Handles three distinct paths based on marker state — fresh install (opt-in activation), re-enable…
domain-expert
Use this skill during /plan (between scope validation and writing the plan artifact) to inject domain-specific context, gap questions, and regulatory concerns into the plan. Triggers automatically when the plan skill evaluates the task and scope.md against the domain registry in domains/index.json using semantic…
plan
Use this skill at the START of every coding task — new builds, bug fixes, and change requests. Classifies the work item, validates it against project scope, produces a high-level estimate, proposes a technology stack, and checks stack compatibility. Writes a plan artifact to .claude/sdlc/plans/ that every downstream…
configure
Use this skill when the user runs /configure, /configure --needs, or /configure --check. Also auto-invoked by env-detect.sh on fresh install (Layer 0) and by skills that find required config missing at runtime (Layer 2). Guides setup of config/tools.json and config/tools.local.json through a question bank; handles…
status
Use this skill when the user asks "where am I", "what's the current task", "what's blocking me", "show status", "what needs sign-off", or "what's next". Prints a snapshot of the active plan, gate, sign-off progress, and next action. Reads only — writes nothing.
analyze
Use this skill after Phase 1 Plan to create or intake requirements for a task. Produces requirements with stable IDs (REQ-001, REQ-002, ...), validates each requirement against the project's scope statement, and — critically — halts and asks for UX designs and brand guidelines whenever the work touches a frontend or…
