What it does
Asyncredux Error Handling is an agent skill from marcglasberg/async_redux. Implement comprehensive error handling for actions. Covers the wrapError() method for action-level error wrapping, GlobalErrorObserver for app-wide error transformation and logging/monitoring (including Persistor errors, where the action is null), and the error handling flow (before → reduce → after).
Its SKILL.md is about 2.7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Error handling. The repository describes itself as: Powerful State Management for Flutter. Docs: https://asyncredux.com.
When your agent uses it
- Tasks that involve Error handling
Example prompts
- “/asyncredux-error-handling”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- If before() throws an error, the reducer doesn't execute and state remains unchanged
- If reduce() throws an error, execution halts without state modification
- The after() method always runs, even when errors occur (like a finally block)
What it can do on your machine
Read from SKILL.md and the folder at commit bbc4303. 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 Error Handling loads about 2.7k tokens when it runs. Until then it costs about 83 tokens; SKILL.md has 608 words of instructions outside code blocks.
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 608 words (~2,703 tokens).
“AsyncRedux provides a comprehensive error handling system with multiple layers: action-level wrapping, global error transformation, and error observation for logging/monitoring.”
