What it does

Author a prompt-enhancement system prompt for a new ecosystem and register/update it on the orchestrator's prompt-analysis service. Use when onboarding a new ecosystem (e.g. happyhorse, a new Flux variant, a new Wan video version) and the user provides the ecosystem key plus a reference link, model card, or description. Produces a guide that mirrors the structure and tone of existing ecosystem guides so the prompt-analysis tool behaves consistently.

What this skill changes about the agent has not been set out here as a list. Its SKILL.md, shown below, says it in the author’s own words.

The skill itself

A skill is instructions the model reads, so you can see what you are getting: below is the start of its SKILL.md. The front matter loads with every session, the body loads when the skill triggers, and the whole file comes with the install.

6# Add Prompt Enhancement Guide

8The orchestrator runs a prompt-analysis service that, per ecosystem, takes a user's prompt and produces structured feedback + an enhanced rewrite. Each ecosystem has its own system prompt tuned to the model's prompting conventions (tag vs natural-language, weight syntax, negative-prompt support, text rendering, camera/motion vocab for video, etc.).
9
10This skill authors a new system prompt for an ecosystem the user names and (optionally) deploys it to the orchestrator.
11
12## Scope: image and video ecosystems only
13
14**Do not write guides for 3D, audio, or any other modality** — tripo, hunyuan3d, polygen (image-to-3D) and ace (audio) are explicitly out of scope, as is anything else non-image/video that appears later. If the user names one, say it is out of scope and stop.
15
16The guide template below is built entirely around subject / lighting / camera / composition / style. None of that describes "generate a mesh from this image" or "generate a song," so a guide written from this template for those modalities would be confidently wrong rather than merely thin. Leaving them on the built-in fallback is the deliberate choice.
17
18## Inputs the user must provide
19
201. **Ecosystem key** — the ecosystem's key from packages/civitai-shared/src/basemodel.constants.ts, lowercased. MiniMaxH3 → minimaxh3, Flux1Kontext → flux1kontext, WanVideo-25-I2V → wanvideo-25-i2v, HyV1 → hyv1. Confirm the key exists in that file before using it. (src/shared/constants/basemodel.constants.ts is a one-line re-export shim of the same module, not a stale duplicate — importing from either path is fine.)
21
22 **It is the AIR ecosystem value, lowercased** — the same string that appears in urn:air:<ecosystem>:.... getAirEcosystem in [air.ts](../../../src/shared/utils/air.ts) is the single source for both: stringifyAIR uses it, and so does createPromptEnhancementStep. If you know a model's AIR, you know its prompt-analysis key.
23
24 The consequence to watch: getRootEcosystem follows parentEcosystemId, so a child ecosystem never appears in an AIR and never reaches prompt analysis. Pony, Illustrious, and NoobAI all arrive as sdxl. Check parentEcosystemId before writing a guide — if the target has a parent, the guide belongs on the parent and has to serve every sibling.

Why you can read it

Nothing in a skill executes. The client loads the text and the model follows it, so a skill can be audited the way a runbook is — by reading it.

What it costs in context

Skills are not billed by the call. They are paid for in context: every token the instructions occupy is a token your code, your diff and your conversation cannot use. Here is what this one takes and when it takes it.

≈130

Ten skills this size would take about 54% of the window before you open a file.
050k100k150k200k context window

10.8k tokens, estimated from the bundle at four bytes to the token, held for the rest of the session once it triggers. Heavy. Teams tend to install this one per project rather than globally, and load it only when the job comes up.

Servers bill, skills cost

A server charges by the month. A skill charges once per session, in context, and then keeps charging it for as long as the session lives.

Before and after

The same question, put to the same model twice: once as it comes, and once with these instructions loaded.

No worked example has been published for this skill yet.

The procedure it runs

The procedure has not been set out here step by step. It is in the body of its SKILL.md: the start of it is shown above, and the whole file comes with the install.

Prose, not code

These steps are written for a model to follow, not executed by a runtime. It can still be told to skip one, and it will say so when it does.

Servers it uses

None. This skill calls no MCP servers at all.

Everything it needs is in the instructions, so it works in a project with nothing connected — the model reads the file and changes how it works with what it can already reach.

Its SKILL.md does not declare which tools it asks the agent for, so what it touches is whatever the instructions themselves ask for — read them before you install it.

What it asks for
Writes filesnot declared
Network accessnot declared

This SKILL.md carries no allowed-tools line, so neither is declared. A skill grants no permissions of its own — it can only ask for tools your client already has.

What it will not do

Every skill is narrow, and the useful ones say where they stop. These are the jobs this one is the wrong tool for.

What this skill is not for has not been published here. Nothing is implied by that: it is a section the author has not filled in.

What is in the bundle

8 files, 109.7 kB on disk. Mostly text — the instructions the model reads — with 6 scripts in it that your client would run only if the instructions tell it to.

  • SKILL.md33.7 kB
  • audit.mjs12.5 kB
  • build-candidates.sh1.5 kB
  • manage.mjs23.2 kB
  • measure.mjs15.6 kB
  • prompts.json9.5 kB
  • rewrite.mjs9.5 kB
  • run-queue.mjs4.2 kB
What is not in it

A skill installs nothing and depends on nothing: it is a folder your client reads. This one carries 6 scripts beside the text, so the bundle is 8 files you can review in full before installing. The Apache-2.0 licence covers the templates and examples as well as the instructions.

Install

Installing copies the bundle into your project. Nothing runs at install time — the files sit on disk until the model reads them.

# Add Prompt Enhancement Guide · 10.8k tokens when loaded · macOS, Linux mkdir -p .claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/add-prompt-enhancement-guide/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/add-prompt-enhancement-guide" ] && { [ ! -e .claude/skills/add-prompt-enhancement-guide ] || { mv .claude/skills/add-prompt-enhancement-guide "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/add-prompt-enhancement-guide" .claude/skills/ && echo "Installed .claude/skills/add-prompt-enhancement-guide"

Windows PowerShell says 'running scripts is disabled on this system'? Run Set-ExecutionPolicy -Scope CurrentUser RemoteSigned once, or type npx.cmd instead of npx (codex.cmd, gemini.cmd, grok.cmd likewise). PowerShell 7 needs neither. Writes to .claude/skills/add-prompt-enhancement-guide/ in the current project. For every project instead, run mkdir -p ~/.claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/add-prompt-enhancement-guide/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/add-prompt-enhancement-guide" ] && { [ ! -e ~/.claude/skills/add-prompt-enhancement-guide ] || { mv ~/.claude/skills/add-prompt-enhancement-guide "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/add-prompt-enhancement-guide" ~/.claude/skills/ && echo "Installed ~/.claude/skills/add-prompt-enhancement-guide" (macOS, Linux) — or add --global to the npx line. The curl line replaces .claude/skills/add-prompt-enhancement-guide/ only after the download succeeds, so files left there by another skill of the same name, or by an older release, do not mix in. A copy already there is moved aside, not deleted, and the line prints where.

Which clients pick it up on their own

A skill is a folder of text. Most of these read a skills folder and pick it up without being told; the rest take the same folder another way — an upload in the app, a parameter on an API call — and then choose it by its description just the same.

Versions

Its author publishes no version number, so there is nothing here to pin to: what you install is the folder as it stands today. Instructions change more often than APIs do — a skill can be rewritten entirely without anything it depends on moving.

Pinning

Nothing to pin to: this skill carries no version number of its own. What you install is what the folder holds on the day you install it.
