Scenario Text Overlay

What it does

When your agent uses it

• Text must appear letter-perfect on generated media: taglines
• Styled rich cards composited over Scenario images and video

Example prompts

• “/scenario-text-overlay”

Requirements

• Python 3
• Node.js

Workflow steps

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

1. 1Payload, with the changeable line as a variable
2. 2python3 overlay.py --payload super.json --out super.png, then open super.png: the line must read exactly as written, shrunk to fit the box.
3. 3Upload with upload_asset, then asset_update with the payload JSON as metadata.description and asset_add_tags with ["text-overlay"]…
4. 4Composite over the spot: model_schema_get on model_scenario-compose-video, then model_run with the base video at zIndex 0 and the super as…
5. 5The French variant is the same payload with one value edited, never a new template.

What it can do on your machine

Read from SKILL.md and the folder at commit f6f8ab7. 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 4 files in scripts/ (Python), which the agent can run.

  Shell commands in SKILL.md call:

  • python3
  • pip
  • npx

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

• Network

  No URLs in SKILL.md. Its commands use pip and npx, which can reach the network depending on how they are called.

  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

Scenario Text Overlay loads about 1.8k tokens when it runs, and up to ~3.8k if it reads all its reference files. Until then it costs about 90 tokens; SKILL.md has 816 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~90

When it runs · the whole SKILL.md, loaded when a task matches

~1.8k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~3.8k

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

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); the scripts in this folder are not scanned.
