console-log
Skill627 starsChanged 8 days agoMITView on GitHub
Choose between `console.warn`, `console.error` and no log at all, knowing Datadog RUM reports every `console.error` as an error event. Read when adding or changing a `console.error`, `console.warn` or `console.log` call in app or package code, or when Datadog shows error events for expected or recoverable failures.

The file
We split this skill into the rules it gives an agent
3 rules. About 0 are common, 1 is distinctive, and 2 are very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈1
Distinctive · estimate
This author's own choices. Worth a look.
2
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Very specific: line 10
Use console.warn for expected or recoverable errors (network failures, optional feature unavailable, etc.)
- Very specific: line 11
Use console.error only for illegal/unexpected program states that should never occur in production
- Distinctive: line 12
Prefer dropping the log entirely when the error is neither actionable nor surprising
≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.
Files
Console Logging Convention
console.error is intercepted by Datadog RUM and forwarded as an error event.
- Use
console.warnfor expected or recoverable errors (network failures, optional feature unavailable, etc.) - Use
console.erroronly for illegal/unexpected program states that should never occur in production - Prefer dropping the log entirely when the error is neither actionable nor surprising
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

- Partly
- It didn't
Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
