asset-registrar

asset-registrar is a skill for Claude Code, Codex from WAJDA9/flutter-agent-skills. It costs 31 tokens per session (240 once invoked), scanned A, original, MIT.

A tool that checks an assets folder and lists its files in a Flutter project's pubspec.yaml. Assets are bundled files such as images and fonts that an app loads at runtime.

In plain words
What is it for?
Use it after adding images or fonts, or when Flutter cannot find an asset. It checks the asset folders and updates the Flutter asset declarations.
Why use it?
Flutter can fail with an asset-not-found error when a file is not declared in pubspec.yaml. Registering the folders makes those files available to the app.

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

asset-registrar 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 11d 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.

What it actually says

Instructions

When the developer adds new images or fonts, or complains about an "Asset not found" error:

  1. Use the list_dir tool to check the contents of the assets/ directory (e.g., assets/images/, assets/icons/).
  2. Read the pubspec.yaml file.
  3. Ensure that the flutter: section has an assets: block, and that the relevant folders are declared.
    • It is highly recommended to declare the directory (e.g., - assets/images/) rather than individual files, to cover all contents.
  4. If missing, use replace_string_in_file to add the required asset paths to the pubspec.yaml. Note that YAML indentation is strict; assets: must be indented under flutter:.
  5. Run flutter pub get via the terminal.
  6. Let the user know the assets were successfully registered and are ready to be used via Image.asset().
Changes

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.
