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 | $0.00216 | $0.00216 |
| Opus 5 | $0.00108 | $0.00108 |
| Sonnet 5 | $0.00043 | $0.00043 |
| Haiku 4.5 | $0.00022 | $0.00022 |
Grade A, and why
XActions legacy-src.instructions.md 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 3d 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
Legacy Server (src/)
Status: Being migrated into packages/. For new features, prefer packages/core/.
This code still works and powers the dev server (pnpm dev) and CLI start command.
Architecture
src/server/— Express + Socket.IO, routes, socket handlers, turn manager, provider factorysrc/client/— Browser client: Socket.IO + Web Audio API + WebRTCsrc/browser/— Puppeteer automation for X Spaces (being migrated topackages/core/src/browser/)src/audio/— Audio bridge, PCM capture, WAV encoding
Rules
- Don't add new features here — implement in
packages/core/instead - Don't modify
server.js(root) — it's the compiled legacy entry point - Keep changes minimal: bug fixes and migration work only
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.
