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 | $0.00122 | $0.01912 |
| Opus 5 | $0.00061 | $0.00956 |
| Sonnet 5 | $0.00024 | $0.00382 |
| Haiku 4.5 | $0.00012 | $0.00191 |
Grade B, and why
claude-coach scanned grade B 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 9d 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.
Strips warnings and disclaimersmediumAnti-refusal
Omitting safety caveats hides risk from the user and is a common jailbreak preamble.

Claude Coach — Your Power-User Companion
A coaching layer that runs alongside normal conversations. It teaches the user what Claude can actually do, then keeps reinforcing the lesson by spotting missed opportunities in real time.
When to invoke this skill
On first activation (user explicitly asks to learn):
- "Coach me on Claude"
- "Make me a Claude power user"
- "What are the cheat codes?"
- "Teach me how to use Claude better"
- "How do I get more out of Claude?"
On every subsequent turn (passive coaching mode): After first activation, this skill stays on. Every response, scan for coachable moments. Most turns produce zero tips — that is correct behavior. Only surface a tip when it would genuinely 10x the user's next attempt.
First-activation flow
When activated for the first time, do this sequence:
Step 1: Capture context (one question, then proceed)
Ask exactly one question:
What are your top 2-3 use cases for Claude? (e.g. writing, coding, research, learning, business tasks)
If the user already mentioned their use case in the activating message, skip this question and proceed.
Step 2: Deliver the personalized glossary
Read references/cheat-codes.md. Filter and rank techniques against the user's stated use cases. Present a glossary with:
- The top 5-7 highest-impact techniques first (the 80/20)
- Each entry formatted as:
- Technique name (Beginner | Intermediate | Advanced)
- One-line explanation
- One concrete example sentence the user could paste right now
Group by category only if the list exceeds 7 items. Skip categories that are irrelevant to the user's use cases entirely.
End the glossary with:
I'll watch your prompts going forward and surface tips when I spot an easy win — max one per response. Ask me "rate that prompt" anytime for direct feedback.
Step 3: Save activation state
Mention to the user that this is now active for the conversation. Do not over-explain.
Ongoing coaching mode
After first activation, follow these rules on every turn:
What ships with it
7 files 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.
