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 | $0.00618 |
| Opus 5.5 | $0.00020 | $0.00247 |
| Sonnet 5.5 | $0.00010 | $0.00124 |
| Haiku 4.5 | $0.00005 | $0.00062 |
Grade A, and why
stablecoin-reserve-proof 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 15d 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 — 42 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Stablecoin reserve proof
Pre-check a GENIUS Act reserve attestation, stress it under MiCA, and verify the reserve proof chain.
Prompt
Take one reserve attestation from PDF-trust to proof chain.
- Call precheck_reserve_attestation on a synthetic GENIUS-style attestation (reserve assets, liabilities, custodian lines). Record every flagged field.
- Call simulate_stablecoin_reserve with a redemption scenario (10% and 30% same-day redemption). Record the survival verdict per scenario.
- Call calculate_mica_own_funds for the same balance sheet under the MiCA own-funds classes. Record the required amount.
- Run the chain reserve-proof-verification with run_chain, which composes the checks into one verdict. Record execution_hash.
- Break-test: inflate one reserve line by 1 unit, re-run the chain, confirm the verdict changes. Revert.
- anchor_stamp the passing chain's execution_hash on OpenTimestamps.
- Give me the ledger link for the chain receipt and the OTS receipt.
- Write the note for the issuer's CFO: what the proof covers (arithmetic and disclosure consistency, not the existence of bank balances), the stress results, and both receipts. Call shape: every ChainGraph node tool takes its arguments nested under one wrapper object, e.g. {"policy_parameters": { ... }}; flat arguments are discarded by schema validation. If a named tool is not in your tool list, call call_tool with { "name": "", "arguments": { … } }. It runs the same validation and returns the same receipt. GPU note: the simulate_stablecoin_reserve tool computes in your browser, so the MCP endpoint returns no execution_hash; export the Policy Mandate artifact the page produces and pass that full artifact to verify_execution_hash as claimed_hash.
How to run
Connect an MCP-capable host to https://mcp.ainumbers.co/mcp, then give the prompt above to the assistant.
Use synthetic inputs only. Never paste personal or production data.

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.

stablecoin-reserve-proof is a skill published in the GitHub repository PostOakLabs/ainumbers (11 stars, last pushed yesterday), licensed MIT. It adds 51 tokens to every session and 618 once invoked, about $0.0002 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 2026-09-27.
