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 | $0.00000 | $0.01306 |
| Opus 5.5 | $0.00000 | $0.00522 |
| Sonnet 5.5 | $0.00000 | $0.00261 |
| Haiku 4.5 | $0.00000 | $0.00131 |
Grade A, and why
start 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.
The source is not reproduced here
A licence we could not identify
The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.
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.

start is a skill published in the GitHub repository shrwnsan/vibekit-claude-plugins (7 stars, last pushed 2d ago), with no licence file. It costs nothing until one of its globs matches a file; then it loads 1,306 tokens. 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 2026-09-10.

quiz-me
Post-work comprehension check: a self-contained HTML report of a completed change (context, intuition, decisions) with a quiz at the bottom that tests the human, not the artifact; also recalls prior quizzed work. Non-gating by default; the quizpolicy userConfig tunes offer cadence. Use when the user says 'quiz me'…
eli5
Dead-simple VISUAL explainer. Produces a visual HTML explainer that assumes zero prior knowledge: one idea per diagram, minimal text. Works on a codebase object (a module, a tradeoff, an incident) or a general concept, and grounds in the real artifact before drawing anything. Use when: 'ELI5', 'explain like I'm five'…
illustrate
Visual explainer for a concept or codebase topic, one idea per diagram, grounded in the real artifact and written as a markdown record plus an interactive page (markdown only on request). Presets: newcomer (default) and zero-knowledge (ELI5). Options: an STE register, and a video view too when explainer-video is…
hold-my-hand
Standing posture for multi-step work: only the current phase (exact steps, expected output, common failure, who acts, advancing reply), later ones as a 'Phase 1 of 8' count. Use when: 'hold my hand', 'walk me through this', 'one step at a time', 'one phase at a time', 'don't show me the next step yet', 'guide me…
prerequisites
Read-only report of external tools the enabled plugin fleet declares, and which of them are missing. Use when a hook says a formatter or CLI is missing, or when asking whether this machine has what the enabled plugins need. Never installs.
grounding
Ground an approach in how a Dometrain course teaches it, via the Dometrain MCP server, and cite lessons with timestamped deep links. Use when: 'implementing', 'designing', 'reviewing', or 'debugging' anything covered by a Dometrain course: C#/.NET, ASP.NET Core, EF Core, testing, design patterns, architecture…
