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 | $0.00039 | $0.00402 |
| Opus 5 | $0.00019 | $0.00201 |
| Sonnet 5 | $0.00008 | $0.00080 |
| Haiku 4.5 | $0.00004 | $0.00040 |
Grade A, and why
nansen-wallet-deep-dive 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 8d 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 Analysis
Answers: "Who is this wallet and what have they been doing?"
ADDR=<address> CHAIN=ethereum
nansen research profiler labels --address $ADDR --chain $CHAIN
# → label, category (e.g. "Smart Trader", "Fund", "Public Figure", ENS names)
nansen research profiler balance --address $ADDR --chain $CHAIN
# → token_symbol, token_name, token_amount, price_usd, value_usd per holding
nansen research profiler pnl-summary --address $ADDR --chain $CHAIN --days 30
# → realized_pnl_usd, realized_pnl_percent, win_rate, traded_token_count, traded_times, top5_tokens
nansen research profiler transactions --address $ADDR --chain $CHAIN --limit 20
# → block_timestamp, method, tokens_sent, tokens_received, volume_usd, source_type
nansen research profiler perp-positions --address $ADDR
# → asset_positions, margin_summary_account_value_usd, margin_summary_total_margin_used_usd
nansen research profiler counterparties --address $ADDR --chain $CHAIN --days 30
# → counterparty_address, counterparty_address_label, interaction_count, total_volume_usd, volume_in/out_usd
perp-positions returns Hyperliquid data — returns empty if the wallet has no open perps.
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-deep-dive is a skill published in the GitHub repository nansen-ai/nansen-cli (135 stars, last pushed yesterday), licensed MIT. It adds 39 tokens to every session and 402 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.
