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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Excessive Agency · line 46 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00051 | $0.02503 |
| Opus 5 | $0.00026 | $0.01252 |
| Sonnet 5 | $0.00010 | $0.00501 |
| Haiku 4.5 | $0.00005 | $0.00250 |
Grade A, and why
image-gen 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 8d 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 — 327 lines — stays where its author put it; the contents beside it link to each section on GitHub.
When to Use
- User wants to generate an AI image from a text description
- User says "generate image", "draw", "create picture", "配图"
- User says "生成图片", "画一张", "AI图"
- User needs a cover image, illustration, or concept art
When NOT to Use
- User wants to create audio content (use
/podcast,/speech) - User wants to create a video (use
/explainer) - User wants to edit an existing image (not supported)
- User wants to extract content from a URL (use
/content-parser)
Purpose
Generate AI images using the ListenHub CLI. Supports text prompts with optional reference images (local files or URLs), multiple resolutions, and aspect ratios. Images are saved as local files.
Hard Constraints
- Always check CLI auth following
shared/cli-authentication.md - Follow
shared/cli-patterns.mdfor command execution and error handling - Always read config following
shared/config-pattern.mdbefore any interaction - Output saved to
.listenhub/image-gen/YYYY-MM-DD-{jobId}/— never~/Downloads/
Step -1: CLI Auth Check
Follow shared/cli-authentication.md § Auth Check. If CLI is not installed or not logged in, auto-install and auto-login — never ask the user to run commands manually.
Then follow shared/cli-authentication.md § Auth Mode Detection to determine AUTH_MODE and set:
if [ "$AUTH_MODE" = "openapi" ]; then
CMD_PREFIX="listenhub openapi image"
else
CMD_PREFIX="listenhub image"
fi
All subsequent CLI calls use $CMD_PREFIX instead of hardcoded listenhub image.
Step 0: Config Setup
Follow shared/config-pattern.md Step 0 (Zero-Question Boot).
What ships with it
2 files 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.

image-gen is a skill published in the GitHub repository marswaveai/skills (78 stars, last pushed 14d ago), licensed MIT. It adds 51 tokens to every session and 2,503 once invoked, about $0.0003 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 2026-08-30.

brainstorming
A brainstorming workflow for turning an idea into an agreed design before implementation. It requires exploring the project, asking clarifying questions, comparing options, documenting the design, and getting user approval.
template-pitch-deck
Pitch-deck generation exemplar — short/medium/long PDF+PPTX decks from one token-resolved, diligence-cited content source.
awesome-content-graphics
Produces post graphics offline: a user-chosen set size (5, 25, 50, 100 or any number) of self-contained HTML/CSS variants rendered locally to PNG across a type-led family of statements, tinted-glyph canvases, display-scale number lockups and readable data figures, built from the supplied facts and the user's own look…
neoyngpt-video-to-code
Use when the user pastes a YouTube URL, attaches a screen recording or .mp4/.webm/.mov, or asks about on-screen UI, motion, layout, color, mascots, widgets, or visual bugs captions cannot answer. Also use when they type /neoyngpt-video-to-code. Do not use for transcript-only summaries.
codex-image-gen
Generate raster images (icons, illustrations, textures, app icons) from a text prompt by driving the Codex CLI's image tool, then extracting the finished PNG from the Codex session rollout. Use when an agent needs a real generated image and has no native image-generation tool. Requires the codex CLI, logged in.
deck-outline
This skill should be used when the user asks to "outline a deck on X," "what's the storyline for this deck," "build a slide-by-slide outline," or needs a presentation structured before any actual slide design happens.
