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 | $0.02819 | $0.02819 |
| Opus 5.5 | $0.01128 | $0.01128 |
| Sonnet 5.5 | $0.00564 | $0.00564 |
| Haiku 4.5 | $0.00282 | $0.00282 |
Grade B, and why
Sparo-OS AGENTS.md scanned grade B 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 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.
Sends data to an external URLmediumData exfiltration
A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

Project Overview
Sparo OS is an Agentic OS for building and running intelligent apps. The first-class product surfaces are the Tauri desktop app and the CLI, both backed by shared Rust core services. The React/TypeScript Web UI is the desktop app surface.
Focus routine development on:
src/apps/desktop- Tauri 2 desktop shell, commands, capabilities, and desktop-only integration.src/apps/cli- CLI command surface, terminal/TUI rendering, and CLI-only integration.src/web-ui- React 18 + TypeScript UI used by the desktop app.src/crates/core- platform-agnostic business logic, agent runtime, services, storage, paths, and tools.src/crates/events- platform-agnostic event contracts.src/crates/transport- adapters between core/events and app surfaces.
Do not describe or design features around a general-purpose app server target unless the user explicitly asks for it. The supported product paths are desktop + Web UI and CLI; Remote Connect relay is a separate infrastructure crate, not a Sparo app server.

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.
