What it does

Tesseract Design is an agent skill from mirage-hq/Tesseract. Create and revise static visual designs as editable Tesseract compositions and rendered PNGs, including posters, social graphics, slide layouts, diagrams, and web/UI mockups. Use when the requested deliverable is a design image.

Its SKILL.md is about 990 tokens, which your agent loads only when the skill is triggered. The skill folder holds 11 other files, including reference files and assets (for example `agents/openai.yaml`, `references/conversion.md` and `references/installation.md`).

It sits in Frontend & Design, covering UI design, Frontend development and Social media graphics. The repository describes itself as: Tesseract by Mirage — CLI releases and agent skills for creating and editing videos.

When your agent uses it

  • The requested deliverable is a design image
  • Tasks that involve UI design
  • Tasks that involve Frontend development

Example prompts

  • “/tesseract-design”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Resolve this skill's root from the directory containing this SKILL.md. Follow installation, check the required CLI version once per…
  2. Follow static authoring to create or revise the portable document, set its actual canvas dimensions, import fonts/images, and save…
  3. Keep text, shapes, diagram elements, and layout geometry as native editable layers. Use images for photography, logos, and other supplied…
  4. Render a PNG early, open it, and revise the saved composition. Review hierarchy, alignment, spacing, line breaks, clipping, image crops…

What it can do on your machine

Read from SKILL.md and the folder at commit fbc9458. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Tesseract Design loads about 986 tokens when it runs, and up to ~5.7k if it reads all its reference files. Until then it costs about 61 tokens; SKILL.md has 518 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~61
When it runs · the whole SKILL.md, loaded when a task matches
~986
With references · SKILL.md plus every file in references/, read only if the agent opens them
~5.7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 518 words (~986 tokens).

“For converting files to or from other editing tools, such as Premiere Pro or After Effects, read conversion. When opening shared or older .tsrct files, updating tools, or investigating load/render differences, read versions and compatibility.”
