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 | $0.00096 | $0.06417 |
| Opus 5 | $0.00048 | $0.03209 |
| Sonnet 5 | $0.00019 | $0.01283 |
| Haiku 4.5 | $0.00010 | $0.00642 |
Grade A, and why
lean-canvas 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 7d 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.

Lean Canvas
Document your business model on one page and systematically de-risk it. Master Ash Maurya's adaptation of Business Model Canvas optimized for startups and uncertainty.
When to Use This Skill

Methodology Foundation
| Aspect | Details |
|---|---|
| Source | Ash Maurya - "Running Lean" (2012), adapted from Osterwalder's Business Model Canvas |
| Core Principle | "Document your Plan A, identify the riskiest parts, and systematically test them." |
| Why This Matters | A business plan is a 60-page guess. A Lean Canvas is a 1-page hypothesis you can test in weeks, not months. It replaces planning with learning. |

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.
