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 | $0.10202 | $0.10202 |
| Opus 5.5 | $0.04081 | $0.04081 |
| Sonnet 5.5 | $0.02040 | $0.02040 |
| Haiku 4.5 | $0.01020 | $0.01020 |
Grade A, and why
sxo AGENTS.md scanned grade A with 2 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 2mo 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.
- `pnpm run test:runtimes` expects: `curl`, `pnpm`, plus `bun` and `deno` installed for their sections. Runs shell commandslowCapability
Expected in a hook, worth knowing in a rule or an instructions file.

Quick Start (TL;DR)

Architecture: ESM-only Node 20+ SSR framework. Dual esbuild outputs (dist/client public, dist/server SSR bundles). Route discovery from pages/ dir, manifest at dist/server/routes.json. JSX via Rust/WASM transformer. Middleware in src/middleware.js.
Style: Small modules, ESM imports, JSDoc on exported utilities. No React patterns. Pages return full HTML docs (<html> + <head>). See .rules/jsx-standards.md for examples, .rules/jsdoc.md for docs, .rules/testing.instructions.md for tests.
Constraints: Only modify src/js/** unless directed. Never edit jsx-transformer/jsx_transformer.js, dist/**, or generated artifacts. No mega-refactors (>300 LOC / >3 files) without confirmation. Preserve AIDEV-* anchors.
Key Files: src/js/esbuild/ (build pipeline), src/js/server/ (dev/prod servers), src/js/config.js (resolution), src/js/cli/ (commands). Read full sections below for details.
Loaders: Custom esbuild server loaders can be configured via CLI flags (--loaders ".svg=file"), env (LOADERS='{"svg":"file"}'), or config file ({"loaders":{".svg":"file"}}). Format supports both .svg and svg notation (dot auto-added). Repeatable flags merge together; comma-separated values supported. Only propagated to dev/build commands. Follow standard config precedence: flags > file > env > defaults.

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.

sxo AGENTS.md is an instructions file published in the GitHub repository gc-victor/sxo (51 stars, last pushed 12d ago), licensed MIT. It adds 10,202 tokens to every session, about $0.0408 per session on Opus 5.5. A static security scan graded it A with 2 findings (makes network calls, runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
