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.

What it costs to keep this loaded
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 | $0.00072 | $0.00415 |
| Opus 5 | $0.00036 | $0.00208 |
| Sonnet 5 | $0.00014 | $0.00083 |
| Haiku 4.5 | $0.00007 | $0.00042 |
Grade A, and why
zk-proofs 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 12d 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
ZK Proofs
When to Use
- Privacy-preserving transactions on Stellar
- On-chain ZK verification in Soroban contracts
- Private voting, identity, or credential systems
- Integrating Circom/Noir with Stellar
Toolchain Status
| Tool | On-Chain Verifiable | Notes |
|---|---|---|
| Circom | Yes (today) | Groth16 via BLS12-381 host functions |
| Noir | Pending BN254 | Attestation pattern until CAP-74 lands |
| RISC Zero | Pending BN254 | Attestation pattern for now |
Groth16 Verification (Circom)
Uses BLS12-381 pairing check host functions (available since Protocol 20).
circuit.circom → r1cs → zkey → proof.json + public.json
↓
Soroban contract verifier
(import soroban-zk-verifier)
Strict Rules
- Only Circom proofs can be verified on-chain today
- Noir and RISC Zero use the off-chain attestation pattern until BN254 lands
- ZK verifier contracts must import
soroban-zk-verifiercrate - Always test with small circuits first — proving is expensive
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.

zk-proofs is a skill published in the GitHub repository rylsherdamz-rgb/stellar-forge (17 stars, last pushed 2d ago), licensed MIT. It adds 72 tokens to every session and 415 once invoked, about $0.0004 per session on Opus 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 2026-08-30.
