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 | $0.00031 | $0.00262 |
| Opus 5 | $0.00015 | $0.00131 |
| Sonnet 5 | $0.00006 | $0.00052 |
| Haiku 4.5 | $0.00003 | $0.00026 |
Grade A, and why
nansen-defi-positions 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
DeFi Exposure
Answers: "What DeFi positions does this wallet have across protocols?"
ADDR=<address>
nansen research portfolio defi --wallet $ADDR
# → protocol_name, chain, total_value_usd, total_assets_usd, total_debts_usd, total_rewards_usd, tokens
nansen research profiler balance --address $ADDR --chain ethereum
# → token_symbol, token_name, token_amount, value_usd per holding
nansen research profiler balance --address $ADDR --chain base
Combine DeFi positions (lending, LPs, staking) with spot balances for a complete picture of on-chain exposure.
Note: portfolio defi may return empty for wallets with no tracked DeFi positions.
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-defi-positions is a skill published in the GitHub repository nansen-ai/nansen-cli (135 stars, last pushed yesterday), licensed MIT. It adds 31 tokens to every session and 262 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.
