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 | $0.00046 | $0.02388 |
| Opus 5 | $0.00023 | $0.01194 |
| Sonnet 5 | $0.00009 | $0.00478 |
| Haiku 4.5 | $0.00005 | $0.00239 |
Grade A, and why
design-team-culture 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 8d 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 — 137 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Design Team Culture
Shape your team's culture intentionally — through leader behavior, rituals, stories, and signals — rather than letting it form by accident from whoever happens to be loudest or most tenured.
Why This Is Best Practice
Adopted by: Edgar Schein's "Organizational Culture and Leadership" is the foundational academic work on organizational culture and has shaped culture design practice at McKinsey, IBM, MIT Sloan, and Harvard Business School for 40 years; Daniel Coyle's "The Culture Code" (based on research in Navy SEAL teams, Pixar, San Antonio Spurs, IDEO) is used as a culture design framework at Google, Netflix, and multiple NBA organizations; Ben Horowitz's "What You Do Is Who You Are" is required reading for founders at Y Combinator and a16z portfolio companies and is used explicitly for culture design at Coinbase, Box, and Lyft Impact: Coyle's research found that team culture quality — specifically the presence of safety signals, vulnerability sharing, and shared purpose — explained more performance variance than IQ, skill, or strategic planning; Deloitte's Global Human Capital Trends (2016, 7,000 organizations) found that 82% of leaders believe culture is a competitive advantage, yet only 12% believe their organization's culture is performing as intended — meaning accidental culture is the default and intentional culture is rare; McKinsey's research on culture and organizational transformation found that companies with explicitly designed cultures achieved 3× higher total shareholder returns than industry peers over 10-year periods Why best: Culture forms regardless of whether a manager pays attention to it — through observed leader behavior, decisions under pressure, who gets rewarded, and who gets tolerated; accidental culture reflects these signals without intentional design, producing whatever the loudest or most senior person's habits happen to be; intentional culture design names the desired behaviors explicitly and then aligns rituals, recognition, and leader modeling to reinforce them; Schein's core insight: what leaders pay attention to, measure, and react to is more culturally powerful than what they say
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.

design-team-culture is a skill published in the GitHub repository jeffreytse/grimoire-core (4 stars, last pushed 23d ago), licensed MIT. It adds 46 tokens to every session and 2,388 once invoked, about $0.0002 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.
