At a glance

Handle user-facing errors with UserException. An agent skill from marcglasberg/async_redux.

  • SKILL.md covers Throwing UserException from…, Converting Errors to…, Setting Up UserExceptionDialog and Customizing Error Dialogs, plus 7 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Asyncredux User Exceptions is an agent skill from marcglasberg/async_redux. Handle user-facing errors with UserException. Covers throwing UserException from actions, setting up UserExceptionDialog, customizing error dialogs with onShowUserExceptionDialog, and using UserExceptionAction for non-interrupting error display.

Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Powerful State Management for Flutter. Docs: https://asyncredux.com.

Example prompts

  • “/asyncredux-user-exceptions”

What it can do on your machine

Read from SKILL.md and the folder at commit a5e5c52. 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 dart).

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

  • Network

    Links to these hosts (documentation or services it may open):

    • asyncredux.com

    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

Asyncredux User Exceptions loads about 1.9k tokens when it runs. Until then it costs about 69 tokens; SKILL.md has 300 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~69
When it runs · the whole SKILL.md, loaded when a task matches
~1.9k

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 300 words (~1,856 tokens).

“UserException is a special error type for user-facing errors that should be displayed to the user rather than logged as bugs. These represent issues the user can address or should be informed about.”
