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 | $0.00089 | $0.01650 |
| Opus 5 | $0.00044 | $0.00825 |
| Sonnet 5 | $0.00018 | $0.00330 |
| Haiku 4.5 | $0.00009 | $0.00165 |
Grade A, and why
apply-golden-circle 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 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.
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 — 63 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Apply Golden Circle
Restructure a vision, pitch, or call to action to lead with Why (the belief or purpose driving the work), then How (the specific approach that makes it distinct), then What (the product or action itself) — because audiences respond to and remember purpose-led communication more than feature-led communication, even when the underlying facts communicated are identical.
Why This Is Best Practice
Why best: Most communication about a product, initiative, or organization defaults to leading with What (the specific thing being offered) and, if there's room, What it does differently (How), with the underlying Why left implicit or omitted entirely. Sinek's specific claim is that this ordering is backwards relative to what actually moves an audience to action or loyalty: leading explicitly with the belief or purpose behind the work, before describing the approach or the specific offering, produces stronger persuasion and identification than leading with the offering itself — the same facts, communicated in reverse order, produce a measurably different audience response.
Sinek, "Start with Why" (2009) and associated TED talk: Sinek's framework — the "Golden Circle" of three concentric layers, Why (purpose or belief) at the center, How (the specific approach) in the middle, and What (the product or action) on the outside — argues that most communicators work from the outside in (What, then How, then Why, if at all), while the organizations and leaders Sinek documents as unusually effective at inspiring loyalty and action communicate from the inside out, leading explicitly with Why. Sinek's TED talk presenting this framework is among the most-viewed TED talks ever recorded, and the book has been widely adopted in leadership and marketing communication training specifically for its practical reordering principle: state the purpose first, then the differentiated approach, then the specific offering — rather than the reverse.
Adopted by: "Start with Why" and the Golden Circle framework are widely taught in marketing, leadership communication, and brand strategy training; Sinek's TED talk on the framework is among the most-viewed talks in TED's history, reflecting broad practitioner and general-audience adoption of the reordering principle it presents. Impact: The framework's practical, widely-adopted claim is specifically about message ordering: communicating the same underlying facts (a product's features, an organization's approach) in Why-How-What order rather than What-How-Why order produces measurably stronger audience identification and motivation to act — a claim Sinek supports with case comparisons between organizations that lead with purpose and otherwise-comparable organizations that lead with product specifications alone.
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.

apply-golden-circle is a skill published in the GitHub repository jeffreytse/grimoire-core (4 stars, last pushed 23d ago), licensed MIT. It adds 89 tokens to every session and 1,650 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 2026-09-03.
