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 | $0.00080 | $0.01643 |
| Opus 5.5 | $0.00032 | $0.00657 |
| Sonnet 5.5 | $0.00016 | $0.00329 |
| Haiku 4.5 | $0.00008 | $0.00164 |
Grade A, and why
apply-opportunity-and-sponsorship-strategy 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 1mo 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 — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Apply Opportunity and Sponsorship Strategy
Read situational openings before they're obvious, and deliberately cultivate sponsors — people who spend their own credibility advocating for you — rather than relying on mentorship or waiting to be noticed.
A note on this skill's name: it draws on a Chinese folk saying, 识天物，傍贵人, whose classical textual source could not be verified through research. It's used here as a mnemonic frame — "read the signs of opportunity, stand near people of influence" — not as an authoritative citation. The actual practice below is grounded in documented modern research, cited separately.
Why This Is Best Practice
Adopted by: Kirzner's concept of entrepreneurial alertness is foundational in entrepreneurship theory; Granovetter's weak-ties research and Burt's structural-holes theory are foundational, widely cited frameworks in network sociology; Sylvia Ann Hewlett's sponsorship research (Center for Talent Innovation) has been adopted as formal corporate sponsorship programs at firms including Deloitte, EY, and Intel.
Impact: Hewlett's research found employees with a sponsor — someone senior who actively advocates for them — request stretch assignments and raises far more often, and advance faster, than employees who have only a mentor. Granovetter's original study found that most job opportunities travel through weak ties (loose acquaintances), not close friends — network position and reach matter as much as who you already know well.
Why best: this separates two relationships that get conflated constantly — a mentor helps you get better through advice; a sponsor spends their own influence moving you forward, often when you're not in the room. Covering both halves — noticing the opening (alertness) and having someone with real credibility advocate you into it (sponsorship) — addresses the full mechanism, not just one piece of it.

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.

apply-opportunity-and-sponsorship-strategy is a skill published in the GitHub repository jeffreytse/grimoire-core (5 stars, last pushed 5d ago), licensed MIT. It adds 80 tokens to every session and 1,643 once invoked, about $0.0003 per session on Opus 5.5. 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.
