About this skill

Jaspr HTML Converter is a skill in rodydavis/signals.dart (819 stars). Its SKILL.md is about 378 tokens. Licence: Apache-2.0.

What it can do on your machine

Read from SKILL.md and the folder at commit 81d64e8. 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 (its code samples are bash).

    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

Jaspr HTML Converter loads about 378 tokens when it runs. Until then it costs about 27 tokens; SKILL.md has 173 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~27
When it runs · the whole SKILL.md, loaded when a task matches
~378

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.

Rules

Converting existing HTML into Jaspr component syntax by hand is prone to errors and wastes time.

  • Rule 1: You MUST ALWAYS use the jaspr convert-html command to convert existing HTML.
  • Rule 2: You MUST NEVER attempt to convert HTML to Jaspr code manually.
  • Rule 3: You MUST take the output from the daemon UNCHANGED and use it exactly as provided.

Usage

To convert HTML to Jaspr code, run one of the following commands in the terminal depending on your source:

From a local file:

bash
jaspr convert-html --file some/path/to/file.html

From a URL:

bash
jaspr convert-html --url https://example.com

The resulting Jaspr code is printed directly to the console. You can then copy this code directly into your component's build method.

Selecting Specific Elements

If you only need a portion of the HTML, you MUST use the --query option with a CSS selector to target specific elements rather than converting the whole file and deleting pieces manually.

bash
jaspr convert-html --file some/path/to/file.html --query "#my-id"

This will only convert and output the element with the id my-id.

Tip: To convert everything inside the <body> tag but exclude the <body> tag itself, use:

bash
jaspr convert-html --file some/path/to/file.html --query "body > *"
