structure-image

structure-image is a skill for Claude Code from big-emotion/agent-atelier. It costs 97 tokens per session (894 once invoked), scanned A, original, MIT.

A planning tool that turns an approved subject report into a sourced single-image social post. It prepares the image brief, short text, alt text, network captions, source details, and supporting quotations.

In plain words
What is it for?
It helps create a title, a short image message, accessibility text, captions, source lists, and citation records for a one-picture post.
Why use it?
It keeps the post focused on one well-supported claim and gives the later production step the words, image reference, and evidence it needs.

Token cost

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.

Security

Grade A, and why

structure-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.

How it starts

The opening of the file, as written. The whole thing — 75 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Structure (single image)

Headings are fixed. Section headings are fixed identifiers: copy them exactly as written in the deliverable templates (English, with the same hash marks), whatever the language of the profile. Only the text under a heading is written in the profile's language.

Turns idea.md and idea.json into a one-picture post. It writes words and picks one image title; it does not render, redesign a layout or read a licence.

idea.md + idea.json  →  structure-image  →  image.json, captions.md, sources.md,
                                            images.json, citations.json  →  produce

Two ways to run it

  • Interactive: show the title, text, alt text and captions, and ask for approval.
  • Studio (project/studio.md exists): the contract wins. Never ask, never block, write only the five files, list every decision under ## Choix faits pour toi in captions.md.

What you read first

  1. inputs/idea.md and inputs/idea.json. Consume the subject report; do not choose a fresh argument. A single image carries one claim: pick the one the sources support best and leave the rest for another format. When idea.json carries a plan, take the claim of its best-sourced step and leave the other steps for another format; beforeWriting lists what the idea step could not verify, and the image never states a claim that depends on it. Without a plan, choose the claim from the report as before.
  2. project/profile.md: language, audience, networks and their register.
  3. On a revision: revision.md and inputs/previous/.

The rule that comes first

Every claim carries its source, and a claim you could not read is not in the piece. A title-only image makes no claim and needs no source.

The image brief: image.json

The shape is references/image.schema.json.

  • Title: eight words or fewer. It is what most people will see.
  • texte: at most two short sentences, twenty words each, subject first and its reference after, plain language. Optional; with it comes a source.
  • alt: required. One description of what the picture shows, 150 characters at most, written for someone who cannot see it. Not "image of…", not the claim.
  • image: an id from images.json and identite, one sentence on what the picture shows, without naming its author or licence.
  • Nothing internal is printed: no "TODO", no "to confirm", no markup.

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.
