Token cost

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.

Security

Grade A, and why

aftermath-perpetuals 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 4d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/check_api_changes.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Fast Routing

Choose one file first; do not load everything by default.

Default preference: start with native perpetuals endpoints (/api/perpetuals/*) because they expose the full Aftermath feature set. Use CCXT endpoints when you specifically need exchange-style compatibility.

  1. CCXT endpoint work -> ccxt.md
  2. Native perpetuals endpoint work -> native.md
  3. SDK method usage -> sdk-reference.md
  4. API failures/retries -> error-handling.md
  5. Trading safeguards -> safety-and-risk.md
  6. DCA and spot limit orders -> dca-and-limit-orders.md
  7. Staking -> staking.md
  8. AMM pools -> pools.md
  9. Coin and LP prices -> prices.md
  10. Builder codes/gas pool/referrals/rewards/rebates/router/metastable/birdeye/dynamic gas/zkLogin/coins -> auxiliary-endpoints.md
  11. Monitoring examples -> monitoring-patterns.md
  12. Edge-case pitfalls -> gotchas.md

Integration Modes

Preferred by default: Native perpetuals (/api/perpetuals/*) for complete API coverage.

Mode Best for Primary file
CCXT compatibility (/api/ccxt/*) Exchange-style payloads and build-sign-submit bots ccxt.md
Native perpetuals (/api/perpetuals/*) Full account/vault previews + tx builders native.md
TypeScript SDK (@aftermath-finance/sdk) Typed app integrations sdk-reference.md

High-Risk Guardrails

  • Sign signingDigest, not transactionBytes.
  • Keep ID types strict: CCXT write accountId (object ID) vs native accountId (numeric).
  • Send native BigInt fields using their exact "...n" wire format where required.
  • Treat preview responses as success/error unions.
  • Re-sync snapshots after stream reconnect before applying deltas.
  • Serialize coin/gas-object-sensitive operations to avoid version conflicts.

What ships with it

14 files 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.

Changes

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.
