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 | $0.00121 | $0.02190 |
| Opus 5 | $0.00060 | $0.01095 |
| Sonnet 5 | $0.00024 | $0.00438 |
| Haiku 4.5 | $0.00012 | $0.00219 |
Grade B, and why
fundos scanned grade B with 2 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 10d 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.

FundOS
FundOS is the system of record for a fund manager's operations. If the user is asking about their fund — its LPs, its money, its portfolio, its documents — the answer lives here, not in your memory. Fetch it.
This skill covers access and safety. The domain skills do the actual work:
| Ask | Skill |
|---|---|
| Issue / calculate / draft a capital call | fundos-capital-calls |
| Distributions, carry, hurdle, GP/LP split | fundos-waterfall |
| NAV, DPI/RVPI/TVPI, capital accounts, fees | fundos-fund-admin |
| Any letter or notice going to LPs | fundos-lp-reporting |
| Portfolio company covenant compliance | fundos-covenants |
| Data room, diligence, document gaps | fundos-vdr |
The safety contract — read this before any write
FundOS is a book of record for real money. Two rules, and they are not negotiable:
- Reads are free. Writes are proposals. Every write endpoint routes into a human
approval queue inside FundOS. A
200on a write means "a GP will see this", not "this happened". Never tell the user a capital call was issued, a covenant was recorded, or a notice was sent. Say it was drafted for approval, and say where. - Never send anything to an LP. You draft; a human sends. This applies to capital call notices, distribution notices, quarterly letters, and write-down disclosures.
If a task seems to require executing a trade, deleting a room or LP record, or granting someone access — stop and hand it back to the user. Those are human-only in FundOS and the API will refuse them.
How to call FundOS
Base URL: https://fundos.vantedgeai.com/api/v1
FundOS is reached through one shared org credential, so you never hold the key. Your
system prompt lists it under "Shared org credentials available to you" with the slug
(normally fundos) and host fundos.vantedgeai.com. If that entry is absent, you have no
FundOS access — say so and stop. Do not ask the user to paste an API key.
Define this helper once per session, then use it for everything:
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.
- 10d ago First seen · 179 lines · 121 tokens per session scan B d8a17b813a5a
fundos is a skill published in the GitHub repository 8vdx1/fundos-mcp (1 stars, last pushed 27d ago), licensed MIT. It adds 121 tokens to every session and 2,190 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it B with 2 findings (subtle steering, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
