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 | $0.00058 | $0.00571 |
| Opus 5.5 | $0.00023 | $0.00228 |
| Sonnet 5.5 | $0.00012 | $0.00114 |
| Haiku 4.5 | $0.00006 | $0.00057 |
Grade A, and why
supply-chain-provenance 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.
What it actually says
Supply chain provenance
Verify the DSCSA T3, the FSMA 204 CTEs, and the DPP carrier for this product.
Prompt
Provenance for one product across three regimes, one receipt.
- Call verify_dscsa_transaction_statement on the synthetic T3 data for the pharma line. Record pass/fail and the trading-party identifiers.
- Call validate_fsma204_cte on the food line's critical tracking events. Record which CTEs are present and which are missing for the KDE pairs.
- Call resolve_recall_trace for both lines: given a synthetic lot, record the trace-up and trace-down paths and their terminals.
- Call validate_dpp_data_carrier on the digital product passport carrier. Record whether the carrier resolves and what data it serves.
- Recall drill: pick one terminal node from step 3 and confirm the trace lists every affected lot, not just the first. Quote the lot count.
- build_session_receipt over the four checks; give me the ledger link.
- Write the provenance note for the quality team: what each regime check covers, the recall path summary, and the ledger link, so a regulator's question is answered by re-running the receipt. 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.
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.

supply-chain-provenance is a skill published in the GitHub repository PostOakLabs/ainumbers (11 stars, last pushed yesterday), licensed MIT. It adds 58 tokens to every session and 571 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.
