Troubleshooting

Issue	Cause	Solution
Non-mql5.com URL	Skill only supports mql5.com	Use other tools for non-mql5.com sites
Article not found	Invalid article ID or removed	Verify URL exists by visiting in browser
User ID not recognized	Wrong user ID format	Use numeric ID from profile URL or exact username
Empty extraction	Rate limiting or site change	Wait and retry, check for site structure changes
Permission denied	Working directory mismatch	Run from $HOME/eon/mql5 directory
Batch too large	Too many articles requested	Limit batch size, use URL list file
Missing dependencies	Required tools not installed	Install curl, jq for extraction
Output encoding issues	Unicode in article content	Ensure UTF-8 output handling

Post-Execution Reflection

After this skill completes, check before closing:

1. Did the command succeed? — If not, fix the instruction or error table that caused the failure.
2. Did parameters or output change? — If the underlying tool's interface drifted, update Usage examples and Parameters table to match.
3. Was a workaround needed? — If you had to improvise (different flags, extra steps), update this SKILL.md so the next invocation doesn't need the same workaround.

Only update if the issue is real and reproducible — not speculative.
