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 | $0.00095 | $0.00984 |
| Opus 5.5 | $0.00038 | $0.00394 |
| Sonnet 5.5 | $0.00019 | $0.00197 |
| Haiku 4.5 | $0.00010 | $0.00098 |
Grade A, and why
celestial-threads 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 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.
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.
How it starts
The opening of the file, as written. The whole thing — 106 lines — stays where its author put it; the contents beside it link to each section on GitHub.
What it does
This prompt instructs an AI image generator to create a highly detailed, surreal depiction of a celestial subject formed from flowing fiber-optic filaments and glowing particles, posed in a graceful curved silhouette with semi-transparent, pearlescent white and deep-blue luminosity. The result is an ethereal, majestic figure set against a dark void, with starlight-like streams, drifting sparks, and magical dust accentuating the glowing, otherworldly atmosphere.

Inputs
textInputs
Pass each text input using --input <key>=<value> flags.
| Variable key | Required? | Description | Defaults |
|---|---|---|---|
SUBJECT |
Required | (none) |
Models and options
This skill's modality is: image.
To discover which model values you can use (and which options keys/values are valid for each model), run:
betterprompt resources --models-only --json
Then filter the returned JSON array to entries where modality is "image".
How to run
Step 1: Collect inputs
First, run betterprompt resources --models-only --json and filter to modality: "image" to discover valid models and available options:
betterprompt resources --models-only --json
Use only the models and option values that appear in the filtered results.
Then collect all inputs from the human:
- Required text inputs:
SUBJECT
- Optional: model and options.
- Present the human with the default model
gpt-image-1and its available options. Look upgpt-image-1in thebetterprompt resourcesoutput (filtered to modality"image") and show itsavailableOptionsas:key: val1, val2 (default), val3 | key2: .... Mark a value(default)if it matches these defaults:{"quality":"medium"}. - If the human does not specify, defaults are used: model
gpt-image-1, options{"quality":"medium"}. Other models from the resources call are also available.
- Present the human with the default model
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.

celestial-threads is a skill published in the GitHub repository BetterPromptme/skills (5 stars, last pushed 3mo ago), licensed MIT. It adds 95 tokens to every session and 984 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
