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 | $0.03290 | $0.03290 |
| Opus 5.5 | $0.01316 | $0.01316 |
| Sonnet 5.5 | $0.00658 | $0.00658 |
| Haiku 4.5 | $0.00329 | $0.00329 |
Grade C, and why
aspicio AGENTS.md scanned grade C 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 4d 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.
Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
`rm -rf dist && vp build`, and confirm the artifact — a size delta or a How it starts

Aspicio — agent guide
Aspicio (Latin: "I look at") — a TypeScript-first 2D drawing viewer (DXF and vector PDF) for the web, with a headless pipeline that also serves AI agents: an HTTP API, an MCP server, and installable skills/plugins. Live demo: https://aspicio.frontsail.app.
Tech stack
| What | Choice |
|---|---|
| Language / runtime | TypeScript; bun (package manager + runtime backend) |
| Toolchain | Vite+ (vp) — dev, build, test (vitest), lint/format (oxlint/oxfmt), pack (tsdown) |
| Rendering | Three.js WebGL (viewer); resvg WASM/native for headless PNG |
| Parsing | DXF: dxf-parser + custom entity handlers; PDF: own zero-dependency parser |
| E2E | Playwright e2e suites: demo + every example app (react/elements/vue/svelte/vanilla/widget) |
| Hosting / deploy | Vercel (custom domains on frontsail.app), prebuilt artifacts deployed from GitHub Actions |
| Agent protocol | MCP (official SDK; stdio + Streamable HTTP) + MCP Apps in-chat viewer |
Architecture in 30 seconds
parse → DrawingDocument → tessellate → { WebGL render | SVG | describe }.
Everything up to WebGL is headless (browser/Node/Workers). Core is
framework-free; embed UI lives once in the Lit web components
(packages/elements), with packages/react, packages/vue, and
packages/svelte as thin veneers over them; the API Worker and MCP
server expose the same pipeline to agents.
Details: docs/architecture.md.
Layout
Everything under packages/ publishes (INV-9) except where marked
private; apps/ and tools/ never publish. A private member of
packages/ may point its exports at source, because no consumer
outside this repo resolves it.
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.

aspicio AGENTS.md is an instructions file published in the GitHub repository frontsail-ai/aspicio (6 stars, last pushed 3d ago), licensed MIT. It adds 3,290 tokens to every session, about $0.0132 per session on Opus 5.5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
