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 | $0.00046 | $0.00547 |
| Opus 5.5 | $0.00018 | $0.00219 |
| Sonnet 5.5 | $0.00009 | $0.00109 |
| Haiku 4.5 | $0.00005 | $0.00055 |
Grade A, and why
pqc-migration-plan 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
PQC migration plan
Find where I am exposed to harvest-now-decrypt-later and get the migration plan.
Prompt
Turn post-quantum anxiety into a dated, receipted plan.
- Call run_pqc_timeline_fit with your synthetic crypto inventory (TLS endpoints, certificate lifetimes, data sensitivity classes). Record the fit verdict and the dates it assumes.
- Call plan_tls_pki_migration for the TLS/PKI estate. Record the migration order, the hybrid periods, and the cutover dates.
- Call classify_blockchain_quantum_risk for any chain exposure in the inventory. Record which assets are harvest-now-decrypt-later sensitive versus signature-only exposed.
- Name the data with the longest secrecy requirement; that is what HNDL actually threatens. Quote its decrypt-by horizon versus the migration date.
- build_session_receipt over the three runs; give me the ledger link.
- Write the plan for the security steering group: the three phases, the HNDL priority list, the ledger link, and the assumption that the timeline tools take standard dates as inputs, so the plan re-runs when NIST dates move. 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.

pqc-migration-plan is a skill published in the GitHub repository PostOakLabs/ainumbers (11 stars, last pushed yesterday), licensed MIT. It adds 46 tokens to every session and 547 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.
