Add Alias

Add new alias mappings or vague skill removals to jobdistill/skill_aliases.py, then re-apply to output files.

Steps

1. Parse user request — the user will specify either:

   • Aliases to merge: e.g. "merge Python 3 into Python"
   • Vague terms to remove: e.g. "remove Programming Languages"

2. Edit jobdistill/skill_aliases.py:

   • For aliases: add entries to SKILL_ALIASES dict (variant → canonical)
   • For vague terms: add entries to VAGUE_SKILLS set

3. Update source CSVs if needed:

   • If the user provides category corrections, update skill_categories.csv
   • If the user provides new alias groups, update skill_alias_mapping.csv

4. Run /remap-skills to re-apply aliases and regenerate skill_analysis_results.csv + dashboard.html.
