gsp-sim is a skill for Claude Code, Codex from esp-mosaico/esp-mosaico-vibe. It costs 65 tokens per session (1,412 once invoked), scanned A, original, no licence file.

A PC simulator for previewing ESP-GSP scenes, which are JSON-based user-interface scenes for ESP-Mosaico, before putting them on the device.

In plain words
What is it for?
It is for authoring and debugging GSP JSON and checking ESP-Mosaico screens without first deploying them to the device.
Why use it?
It lets developers inspect and debug the interface on a computer before flashing it to embedded hardware.

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

gsp-sim 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 today.

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 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.
