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 | $0.00051 | $0.02105 |
| Opus 5 | $0.00026 | $0.01052 |
| Sonnet 5 | $0.00010 | $0.00421 |
| Haiku 4.5 | $0.00005 | $0.00211 |
Grade A, and why
apply-change-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 — 123 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Apply Change Leadership
Lead your team through organizational change by acknowledging what is ending, providing genuine clarity where it exists (and honesty where it doesn't), engaging the team in what they can control, and maintaining psychological safety and momentum through the transition.
Why This Is Best Practice
Adopted by: Kotter's 8-step "Leading Change" framework is the most widely cited change management model globally, used in change programs at IBM, GE, and the US Army; Bridges's "Transitions" model is the standard framework in organizational psychology for understanding the human side of change; the Prosci ADKAR model (Awareness, Desire, Knowledge, Ability, Reinforcement) is used in 80% of Fortune 500 change programs and is the basis for change management certification; McKinsey's change research (2009, 3,000 executives) is the most rigorous large-scale study of what drives change success or failure Impact: McKinsey (2009) found that 70% of organizational changes fail to achieve their intended impact — and that the primary cause of failure is not strategy or planning, but human factors: insufficient communication, unmanaged resistance, lack of leadership alignment; the same research found that change success rates more than doubled when frontline managers actively communicated the change to their teams; Bridges's research (adapted across 30+ years of consulting) found that the "neutral zone" — the ambiguous in-between period when the old way is gone but the new hasn't arrived — is where most change failures occur, and that structured leader behavior during this period determines whether the change produces improvement or dysfunction Why best: Organizational change is typically designed and announced at the executive level, but experienced and navigated at the team level; the gap between the announcement and the lived experience falls entirely on the frontline manager to bridge; managers who wait for complete clarity before communicating leave their teams in information vacuums that fill with rumor; managers who pretend change is simpler than it is lose credibility the moment complexity appears; the manager's specific role in change is neither to design it nor to simply comply with it, but to translate it for the team and maintain stability and engagement during the transition
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.
