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 | $0.00078 | $0.01510 |
| Opus 5 | $0.00039 | $0.00755 |
| Sonnet 5 | $0.00016 | $0.00302 |
| Haiku 4.5 | $0.00008 | $0.00151 |
Grade A, and why
apply-full-lifecycle-investing 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 11d 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 — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Apply Full-Lifecycle Investing
Build the capability to invest in a portfolio company across its entire lifecycle — from seed and early-stage rounds through growth, pre-IPO, and beyond — rather than confining the firm's mandate to a single investment stage. This allows the strongest companies to be backed continuously by the same firm, without forcing a founder to rebuild investor relationships and re-pitch the business fundamentals at every new financing round.
Why This Is Best Practice
Adopted by: Neil Shen (沈南鹏), founder of Sequoia Capital China (now HongShan), built the firm's investment mandate specifically to span the full company lifecycle rather than a single stage — a structural choice documented across Sequoia China's public investment approach and reflected in the firm's continued participation in portfolio companies from seed rounds through their growth and pre-IPO financing. Impact: A single-stage-only VC firm loses continuity with its best portfolio companies once they outgrow that stage, forcing the founder to find and re-establish trust with an entirely new set of investors at each subsequent round — a costly, distracting process during a company's highest-growth period. A full-lifecycle firm instead maintains the accumulated relationship, institutional knowledge of the business, and trust built in earlier rounds, allowing it to continue supporting and investing in the company without this repeated re-establishment cost. Why best: Confining a firm to one stage (e.g., seed-only, or growth-only) optimizes for a specific risk/return profile at that stage but forces a structural handoff of the firm's most valuable, best-performing companies to new investors exactly when the accumulated relationship and business knowledge would be most useful to both the founder and the firm's own ability to keep participating in the company's success — a full-lifecycle mandate specifically avoids this forced handoff.

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.
