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 | $0.00020 | $0.00310 |
| Opus 5 | $0.00010 | $0.00155 |
| Sonnet 5 | $0.00004 | $0.00062 |
| Haiku 4.5 | $0.00002 | $0.00031 |
Grade A, and why
gemini-generate-image 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 10d 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.
What it actually says
Generate Image with Gemini
Create images from text prompts using Google's Gemini AI.
Usage
# Basic generation
uv run python scripts/generate_image.py "a cat astronaut floating in space"
# With options
uv run python scripts/generate_image.py "sunset over mountains" --aspect 16:9
# Save to specific file
uv run python scripts/generate_image.py "abstract art" --output my_image.png
Options
| Option | Values | Default | Description |
|---|---|---|---|
--aspect |
1:1, 4:3, 16:9, 9:16 | 1:1 | Aspect ratio |
--output |
filename | auto-generated | Output filename |
Output
Images are saved to 04-workspace/generated-images/ with timestamp filenames unless --output is specified.
Examples
# Logo concept
uv run python scripts/generate_image.py "minimalist tech logo, blue gradient"
# Marketing asset
uv run python scripts/generate_image.py "happy team working together, modern office" --aspect 16:9
# Social media

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

gemini-generate-image is a skill published in the GitHub repository DorianSchlede/nexus-template (8 stars, last pushed 7mo ago), licensed MIT. It adds 20 tokens to every session and 310 once invoked, about $0.0001 per session on Opus 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 2026-08-31.
