Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

apply-cross-functional-leadership 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 — 136 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Apply Cross-Functional Leadership

Lead projects and initiatives across organizational boundaries by building voluntary cooperation through credibility, reciprocity, and alignment of interests — rather than relying on authority that does not exist in cross-functional contexts.

Why This Is Best Practice

Adopted by: Cohen & Bradford's "Influence Without Authority" is the most widely cited framework for cross-functional leadership and is standard curriculum at HBS, Wharton, and INSEAD executive education programs; McKinsey's organizational design research (2016) found that 83% of Fortune 500 companies use matrix or cross-functional structures for at least 40% of their work — meaning cross-functional leadership without formal authority is the default condition for most initiatives, not the exception; the Project Management Institute (PMI) identifies stakeholder management and influence as the top two differentiating competencies of high-performing project managers Impact: PMI's "Pulse of the Profession" (2023, 5,000+ project professionals) found that insufficient stakeholder engagement is the primary reason for project failure — above technical failure, resource shortage, and scope creep; McKinsey research found that cross-functional teams with designated leaders who actively built influence and aligned stakeholder interests completed projects 40% faster and with 27% higher reported quality than those relying on formal authority or passive coordination; Maister, Green & Galford's trust equation (credibility + reliability + intimacy / self-orientation) predicts stakeholder alignment better than formal role power in cross-functional contexts Why best: In hierarchical contexts, a manager can direct action through formal authority; in cross-functional contexts, the people whose work you depend on have their own managers, their own priorities, and no formal obligation to your timeline; the manager who tries to use authority they don't have creates resentment and passive resistance; the manager who builds genuine alignment by understanding what each stakeholder needs and creating mutual benefit generates the voluntary cooperation that formal authority would have demanded

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.
