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 | $0.00085 | $0.01299 |
| Opus 5 | $0.00043 | $0.00649 |
| Sonnet 5 | $0.00017 | $0.00260 |
| Haiku 4.5 | $0.00009 | $0.00130 |
Grade A, and why
coaching-mode 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 today.
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.

coaching-mode is a skill published in the GitHub repository shrwnsan/vibekit-claude-plugins (7 stars, last pushed today), with no licence file. It adds 85 tokens to every session and 1,299 once invoked, about $0.0004 per session on Opus 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 2026-09-10.

quiz-me
Post-work comprehension check: after a change is complete, generate a self-contained HTML report of what was done (context, intuition, decisions) with a quiz at the bottom that you answer. Verifying the HUMAN absorbed the work, not the artifact. Non-gating by default; the quizpolicy userConfig tunes offer cadence.…
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'…
principles
Metric literacy for what this plugin reports: what cyclomatic complexity, cognitive complexity, Halstead difficulty, lines per file, duplication, coverage, CRAP, and type debt mean, and what none of them can tell you. Four reference files carry the definitions and what each collector computes, each bundled reference…
explain
One-shot plain-language explainer. Drops any concept, code, error, architecture, or the previous assistant response to genuinely plain words (concrete analogy, zero jargon), then layers altitude up only on request (high-school, then peer level). Use when: 'I don't understand this', 'I don't get it', 'what does this…
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…
deps-audit
Use when auditing, updating, or securing project dependencies. Covers multi-language dependency detection, security vulnerability scanning, outdated package identification, unused dependency detection, and update strategies for npm, pip, cargo, and go.
