Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00102 | $0.00424 |
| Opus 5.5 | $0.00041 | $0.00170 |
| Sonnet 5.5 | $0.00020 | $0.00085 |
| Haiku 4.5 | $0.00010 | $0.00042 |
Grade A, and why
nightmarquee-glasshouse-nine scanned grade A 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 6d 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
- Without it: `curl -s "https://nightmarquee.com/api/mcp/prompt/glasshouse-nine?tool=claude"` and use the `text` field. What it actually says
Glasshouse Nine
Walk into the glasshouse as you scroll. Live demo: https://nightmarquee.com/demo/glasshouse-nine
A nursery landing with an honest heartbeat: the hero drifts you through ferns and misted Victorian glass, the bench list shows live counts and keeps sold-out plants visible with their re-rooting dates, and pointing at any row floats a photo of the actual plant.
Get the prompt
The prompt is kept current on nightmarquee.com, so fetch it rather than writing the page from this summary.
- With the NightMarquee MCP server:
nightmarquee_get_prompt(slug: "glasshouse-nine", tool: "claude"). Pass thetoolfor the editor you are in (lovable, bolt, cursor, claude or codex) andbrandfor the person's own name. - Without it:
curl -s "https://nightmarquee.com/api/mcp/prompt/glasshouse-nine?tool=claude"and use thetextfield.
Footage
The demo's clips come with the prompt for anyone signed in to a free NightMarquee account, through the MCP server (nightmarquee_sign_in, then nightmarquee_get_footage(slug: "glasshouse-nine")). Download each clip into public/ under its name before building. Without them, follow the prompt's own footage steps.
Build the page, then compare it with the demo. Prompt licence: https://nightmarquee.com/license
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.
