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 | $0.00046 | $0.00541 |
| Opus 5 | $0.00023 | $0.00270 |
| Sonnet 5 | $0.00009 | $0.00108 |
| Haiku 4.5 | $0.00005 | $0.00054 |
Grade A, and why
nansen-wallet-clustering 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 9d 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
Wallet Attribution
Answers: "Who controls this wallet? Are these wallets related?"
Chain: 0x → --chain ethereum (also base, arbitrum, optimism, polygon). Base58 → --chain solana.
ADDR=<address> CHAIN=<ethereum|solana|base|...> # detect from address format above
# 1. Identity
nansen research profiler labels --address $ADDR --chain $CHAIN
# 2. Related wallets (paginate with --page N)
nansen research profiler related-wallets --address $ADDR --chain $CHAIN
# 3. Counterparties (paginate with --page N; widen with --days 365 if empty)
nansen research profiler counterparties --address $ADDR --chain $CHAIN --days 90
# 4. Batch profile cluster
nansen research profiler batch --addresses "addr1,addr2" --chain $CHAIN --include labels,balance,pnl
# 5. Compare pairs → shared_counterparties, shared_tokens, balances
nansen research profiler compare --addresses "addr1,addr2" --chain $CHAIN
# 6. Historical balances (fingerprint drained wallets)
nansen research profiler historical-balances --address $ADDR --chain $CHAIN --days 90
# 7. Multi-hop trace (credit-heavy — keep --width ≤3)
nansen research profiler trace --address $ADDR --chain $CHAIN --depth 2 --width 3
Expansion: Run steps 1-2 on seed. For each new address found, ask the human before querying. Reserve step 3 for seed only. Stop when: known protocol/CEX · Low confidence · already visited · cluster > 10 wallets. Confidence: High = first funder / shared Safe signers / same CEX deposit. Medium = coordinated movements / related-wallets + label match. Exclude = ENS only, single CEX withdrawal, single deployer. Full attribution rules in REFERENCE.md.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

nansen-wallet-clustering is a skill published in the GitHub repository nansen-ai/nansen-cli (135 stars, last pushed today), licensed MIT. It adds 46 tokens to every session and 541 once invoked, about $0.0002 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.
