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 | $0.00049 | $0.02213 |
| Opus 5 | $0.00024 | $0.01107 |
| Sonnet 5 | $0.00010 | $0.00443 |
| Haiku 4.5 | $0.00005 | $0.00221 |
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
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.
