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 | $0.00054 | $0.02174 |
| Opus 5 | $0.00027 | $0.01087 |
| Sonnet 5 | $0.00011 | $0.00435 |
| Haiku 4.5 | $0.00005 | $0.00217 |
Grade A, and why
apply-coaching-habit 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 — 130 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Apply Coaching Habit
Replace the default impulse to give advice with a habit of asking questions first — so employees bring better-formed problems, develop their own solutions, and become more capable rather than more dependent.
Why This Is Best Practice
Adopted by: Bungay Stanier's "The Coaching Habit" is the best-selling coaching book of the last decade with 1M+ copies sold and trained over 15,000 managers via Box of Crayons programs; Google Project Oxygen (2008–ongoing) consistently identifies "is a good coach" as the #1 behavior distinguishing great managers from average managers, with coaching operationally defined as asking questions and facilitating answers rather than providing answers; the International Coach Federation (ICF) — which certifies 50,000+ coaches globally — identifies "asking powerful questions" as one of eight core coaching competencies Impact: Self-Determination Theory (Deci & Ryan) research confirms that autonomy support — managers asking rather than telling — increases intrinsic motivation, self-reported wellbeing, and performance in organizational settings; Bungay Stanier's pre/post data from 15,000+ managers trained in the 7 questions shows an average shift of 40% reduction in "manager gives direct advice in first 3 minutes" behavior; Google's Project Oxygen analysis found managers who coach (ask) rather than direct (tell) have teams with 15% higher job satisfaction and 10% higher performance ratings Why best: The advice-giving impulse is nearly universal in managers — they got promoted for their expertise, so sharing expertise feels valuable; the failure mode is "create over-reliance": employees bring problems to the manager because the manager solves them faster, the manager's calendar fills with problems that belong to the team, and the team's problem-solving capability atrophies; the coaching habit breaks this cycle not by eliminating advice (sometimes advice is the right answer) but by defaulting to questions first, which forces the employee to engage their own thinking before receiving input
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.
