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 | $0.00063 | $0.02406 |
| Opus 5.5 | $0.00025 | $0.00962 |
| Sonnet 5.5 | $0.00013 | $0.00481 |
| Haiku 4.5 | $0.00006 | $0.00241 |
Grade A, and why
golden-circle-purpose 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.
How it starts
The opening of the file, as written. The whole thing — 290 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Golden Circle purpose framework
Quick reference for purpose-driven brand building using Simon Sinek's Golden Circle methodology and complementary frameworks from Jim Collins, David Aaker, and Marty Neumeier.
"People don't buy what you do, they buy WHY you do it." — Simon Sinek
The Golden Circle
┌───────────────┐
│ WHY │ ← Purpose, cause, belief (LIMBIC BRAIN)
│ ┌───────────┐ │
│ │ HOW │ │ ← Values, process, differentiators (LIMBIC BRAIN)
│ │ ┌───────┐ │ │
│ │ │ WHAT │ │ │ ← Products, services, features (NEOCORTEX)
│ │ └───────┘ │ │
│ └───────────┘ │
└───────────────┘
| Circle | Definition | Brain Region |
|---|---|---|
| WHY | Purpose, cause, and belief: why you exist | Limbic (emotions, decisions) |
| HOW | Unique approach, values, differentiators | Limbic (emotions, decisions) |
| WHAT | Products, services, tangible proof | Neocortex (rational thought) |
The Core Insight: Leading with WHY speaks directly to the decision-making part of the brain.
WHY statement format
Structure: "To _____ so that _____"
- First blank = Your contribution (the action you take)
- Second blank = Your impact (the difference you make)
Examples:
- Simon Sinek: "To inspire people to do the things that inspire them so that, together, we can change our world"
- Airbnb: "To connect millions of people in real life all over the world so that you can Belong Anywhere"
Key Principle: you have only one WHY that never changes. Purpose is discovered, not invented.
WHY discovery process quick reference
From Simon Sinek, David Mead, Peter Docker ("Find Your Why")
Step 1: Preparation
- Find a partner (not spouse/family) to listen and take notes
- Set aside 3+ hours uninterrupted
- Partner's role: ask questions, identify themes, see patterns
Step 2: Share stories (Peaks and Valleys)
- Plot life's significant moments on a horizontal line
- Share 10-12 specific stories
- Include childhood, career, relationships
What ships with it
1 file 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.
