image-prompting SKILL.md skillA
image-prompting from blockrunai/blockrun-mcp is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add blockrunai/blockrun-mcp/image-prompting@git:20261020.af250dbPins git:20261020.af250db in mdr.lock. Pin the fingerprint instead.

Use when generating or editing images via `blockrun_image` — especially with GPT Image 2, Nano Banana, or Grok Imagine for posters, UI mockups, marketing assets, product shots, or anything with on-image text. Turns vague user requests ("make me a cool poster") into structured, text-accurate prompts that actually render what you asked for.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Image Prompting Most image failures are prompt failures. This skill gives the MCP agent a repeatable structure for turning any user request into a prompt that renders clean typography, preserves layout on edits, and avoids AI slop. Defaults are tuned for **GPT Image 2** (best legible text), with fallbacks for Nano Banana, Grok Imagine, and CogView. ## Quick Decision Table **Prices:** per image, and they change — look the model up live rather than trusting a number here: `GET https://blockrun.ai/api/v1/models` (Solana: `https://sol.blockrun.ai/api/v1/models`), find the entry whose `id` is the model below, and read `pricing.per_image` plus `pricing.transaction_fee`. That is the base-size rate; the exact amount for your size and quality is quoted in the HTTP 402 challenge before anything is signed. **Size is the biggest lever:** any dimension above 1024 moves GPT Image 2 to the large tier and roughly doubles the price ($0.064 → $0.127). Ask for `1536x1024` only when you need it. | User wants... | Model | Mode | Size | |---|---|---|---| | Poster / typography-heavy asset | `openai/gpt-image-2` | generate | `1536x1024` or `1024x1536` | …

How to install
mdr add blockrunai/blockrun-mcp/image-prompting@sha256:7875145c401f36a7The line at the top of this page pins the label git:20261020.af250db, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
