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 337 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 | $0.00089 | $0.09707 |
| Opus 5 | $0.00044 | $0.04854 |
| Sonnet 5 | $0.00018 | $0.01941 |
| Haiku 4.5 | $0.00009 | $0.00971 |
Grade A, and why
midjourney-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 9d 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 — 457 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Midjourney image production
Operating boundary
Use this skill to prepare and supervise image work in Midjourney's documented consumer surfaces:
- the Imagine bar, Create/Organize pages, Editor, Personalize page, and Moodboards page on
midjourney.com; - the Midjourney Bot and documented slash commands in Discord.
Do not translate those buttons, slash commands, parameters, job IDs, or image URLs into a supposed REST endpoint, SDK, webhook, environment variable, or machine-to-machine contract. As verified 2026-07-09, Midjourney's Terms prohibit automated tools from accessing, interacting with, or generating through the Services, and its Community Guidelines say that, with rare explicitly granted exceptions, Midjourney does not provide an API or authorized third-party scripts. A Discord command is a user-interface action, not an API.
For an agent-safe workflow:
- Prepare the brief, prompts, parameter matrix, reference manifest, consent record, and QA checklist offline.
- Ask the authorized account holder to submit approved jobs manually in the official website or Discord UI.
- Have the user return downloaded outputs and, when useful, the job ID, seed, final prompt, version, and parameter record.
- Perform selection, comparison, rights review, compositing, typography, metadata, and QA in authorized local tools.
- Never drive the website or Discord with browser automation, self-bots, unofficial clients, scraping, macros, or simulated clicks. Never share an account.
If a customer says they have a rare written Midjourney automation exception, require the actual provider-issued agreement and its technical documentation. Treat that separately from this consumer-interface skill; do not infer authorization from a subscription, bot access, or an internal wrapper.
This skill is about still images. Midjourney documents an Animate creation action that can turn a suitable still into a five-second video, but that is a handoff to a video workflow, not an image-generation parameter recipe here.
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.

midjourney-image is a skill published in the GitHub repository calesthio/generative-media-skills (170 stars, last pushed 2mo ago), licensed MIT. It adds 89 tokens to every session and 9,707 once invoked, about $0.0004 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 2026-09-03.
Other skills, from other repositories
cliptalk-cover-director
Produces evidence-backed cover candidates and reviewable cover variants for a ClipTalk video. Use when the user asks for a cover, poster frame, thumbnail, or multiple cover directions; do not use for timeline editing or social-video reframing.
cliptalk-smart-reframe
Creates a subject-aware, time-varying crop track and a review-only social-format preview from an accepted ClipTalk cut. Use for automatic vertical, square, or portrait reframing; do not use for a fixed manual crop or before content editing is accepted.
cliptalk-content-extractor
Locates and assembles source passages matching a semantic request. Use for extracting explanations, topics, quotes, demonstrations, or other specifically described content.
cliptalk-interview-editor
Produces a coherent interview edit by combining speaker discovery, topic selection, dialogue context, cleanup, subtitles, and preview. Use for interviews, podcasts, testimonials, or question-and-answer recordings.
cliptalk-shortform-hook-director
Finds and assembles a reviewable short-form cut with a strong opening hook. Use for Shorts, Reels, social clips, talking-head cutdowns, or requests for a punchier opening.
cliptalk-social-reframe-exporter
Creates a review-only 9:16, 4:5, 1:1, or 16:9 version from an existing accepted ClipTalk cut, then checks the rendered preview. Use only when a cut already exists and the user asks to adapt it for Shorts, Reels, Douyin, Xiaohongshu, WeChat Channels, or square feeds; do not use when the user still needs content found…
