What it does

Tesseract Editor is an agent skill from mirage-hq/Tesseract. Build or modify a custom browser editor for Tesseract .tsrct files. Use for editor controls, previews, and saving projects; use the motion or video skill for direct project authoring.

Its SKILL.md is about 580 tokens, which your agent loads only when the skill is triggered. The skill folder holds 23 other files, including reference files and assets (for example `agents/openai.yaml`, `examples/bouncing-ball/README.md` and `examples/bouncing-ball/app.js`).

It sits in Media & Creative. The repository describes itself as: Tesseract by Mirage — CLI releases and agent skills for creating and editing videos.

When your agent uses it

  • Editor controls
  • Saving projects
  • Video skill for direct project authoring

Example prompts

  • “/tesseract-editor”

Requirements

  • Node.js

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

    Ships script files (JavaScript, from the files we listed), which the agent can run.

    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 Editor loads about 584 tokens when it runs, and up to ~4.4k if it reads all its reference files. Until then it costs about 50 tokens; SKILL.md has 268 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~50
When it runs · the whole SKILL.md, loaded when a task matches
~584
With references · SKILL.md plus every file in references/, read only if the agent opens them
~4.4k

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 268 words (~584 tokens).

“If the editor needs to import or export other tools’ project formats, 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.”
