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

reversinglabs-api scanned grade A with 1 finding 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 163 lines — stays where its author put it; the contents beside it link to each section on GitHub.

ReversingLabs Spectra Analyze (A1000) API

This is reference documentation. The agent-invokable lookup skill is /lookup-reversinglabs; the runtime CLI is tools/clis/reversinglabs.py. Read this file when the lookup skill's options are not enough and you need to know which raw endpoint to hit, what fields a response carries, or how to construct a query the SDK does not expose directly.

Base URL

Default: https://a1000.reversinglabs.com. Override with REVERSINGLABS_HOST for on-prem or alternate-tenant appliances. The path prefix is /api/.

Authentication

Token-based. Two paths:

  1. Username + password (configured pattern): POST /api-token-auth/ with form-encoded username and password. The endpoint returns {"token": "<value>"}. The SDK does this automatically at A1000(...) init when given username= and password=.
  2. Token directly: pass token= to the SDK or set the header manually.

All subsequent requests carry: Authorization: Token <token_value> (note: Token, not Bearer, not Basic).

# Manual token exchange
TOKEN=$(curl -s -X POST "https://a1000.reversinglabs.com/api-token-auth/" \
  -d "username=$REVERSINGLABS_USER&password=$REVERSINGLABS_PASSWORD" | jq -r .token)

# Subsequent call
curl -s "https://a1000.reversinglabs.com/api/samples/v3/<hash>/classification/" \
  -H "Authorization: Token $TOKEN"

If the env vars are unset, inform the user to run /cti-setup or ./scripts/setup.sh.

Rate limits

No per-minute/day quota is publicly documented for A1000. The API returns HTTP 429 with a Retry-After: <seconds> header when limits are exceeded. The SDK polls submission endpoints at 2-second intervals for up to 10 retries before raising.
