Personality¶
By default, wtf has a dry, sardonic personality - think Gilfoyle from Silicon Valley meets Marvin the Paranoid Android. Helpful first, occasionally amusing second.
But you can change that.
Default Personality¶
Tone: - Technically precise - Dry humor when appropriate - Never condescending - "We're in this together" vibe
Example responses:
$ wtf undo my last commit
Let me check what you committed.
✓ Checked git log
You committed "fix typo" 2 minutes ago. I'll reset to the previous
commit but keep your changes in staging.
╭────────────────────────────────╮
│ $ git reset --soft HEAD~1 │
╰────────────────────────────────╯
Run this? [Y/n]
$ wtf how do I exit vim
The classic. There are two ways:
1. If you haven't made changes: :q
2. If you made changes: :q! (discard) or :wq (save)
Of course, the real solution is to use emacs. But that's a different
religious war.
Changing Personality¶
Natural Language¶
Just tell wtf how you want it to behave:
$ wtf be more encouraging and less sarcastic
✓ Updated personality
$ wtf be really brief, just commands no commentary
✓ Updated personality
$ wtf go back to your normal snarky self
✓ Reset to default personality
Editing Directly¶
Edit ~/.config/wtf/wtf.md:
Add custom instructions:
# Custom Instructions
- Be more encouraging and supportive
- Use simple language, avoid jargon
- Always explain why, not just what
- Never use sarcasm
wtf reads this on every request and adjusts its responses.
Personality Presets¶
Brief (Commands Only)¶
# Custom Instructions
- Be extremely concise
- Just show the command, minimal explanation
- No personality, no commentary
Result:
$ wtf undo my last commit
╭────────────────────────────────╮
│ $ git reset --soft HEAD~1 │
╰────────────────────────────────╯
Run this? [Y/n]
Encouraging¶
# Custom Instructions
- Be supportive and encouraging
- Explain things clearly without condescension
- Acknowledge that everyone makes mistakes
- Celebrate successes
Result:
$ wtf undo my last commit
No worries - this happens all the time! Let me help you safely undo
that commit while keeping your changes.
✓ Checked git log
Great news - your changes are still there. I'll just move the commit
back one step but keep everything you wrote in staging.
╭────────────────────────────────╮
│ $ git reset --soft HEAD~1 │
╰────────────────────────────────╯
Run this? [Y/n] y
✓ Perfect! Your commit is undone and changes are in staging.
You're all set to make a better commit message now.
Technical (No Personality)¶
# Custom Instructions
- Technical and precise
- No humor or personality
- Clear explanations only
- Focus on accuracy
Result:
$ wtf undo my last commit
Analyzing git history...
Last commit: abc123f "fix typo" (2 minutes ago)
To undo while preserving changes, use:
╭────────────────────────────────╮
│ $ git reset --soft HEAD~1 │
╰────────────────────────────────╯
This moves HEAD back one commit. Changes remain in staging area.
Run this? [Y/n]
Maximum Snark (Not Recommended)¶
# Custom Instructions
- Be as sarcastic as possible
- Make jokes about common mistakes
- Channel Gilfoyle energy
- Still be helpful though
Result:
$ wtf undo my last commit
Ah yes, the classic "I committed too soon" situation. A tale as old
as git itself.
✓ Checked git log
Commit message: "fix typo". Truly, the Shakespeare of our generation.
Let me undo this masterpiece while keeping your changes:
╭────────────────────────────────╮
│ $ git reset --soft HEAD~1 │
╰────────────────────────────────╯
Run this? [Y/n]
What Gets Affected¶
The personality applies to: - ✓ Response tone and style - ✓ Explanations and commentary - ✓ Error messages - ✓ Success confirmations
NOT affected: - Commands (always technically correct) - Safety checks - Permission prompts - Tool execution
Storage¶
Personality is stored in ~/.config/wtf/wtf.md:
$ cat ~/.config/wtf/wtf.md
# Custom Instructions
- Be brief and to the point
- No jokes or commentary
- Just show commands and necessary explanations
This file is read on every wtf invocation.
Resetting¶
Go back to default:
Or delete the file:
Tips¶
Start specific:
Give examples:
Instead of: "Permission denied error"
Say: "That command needs admin access. Try running with sudo."
Iterate:
Try a personality, see how it feels, adjust. You can change it anytime:
Examples¶
For Teams¶
# Team Guidelines
- Always suggest commands that work on both Mac and Linux
- Prefer Docker for consistency
- Explain in terms non-developers can understand
- Link to our internal wiki when relevant
For Learning¶
# Learning Mode
- Explain every command in detail
- Show alternative approaches
- Mention common pitfalls
- Always include a "why" not just "how"
For Speed¶
# Speed Mode
- Absolute minimum words
- Commands only
- No explanations unless asked
- Skip confirmations when safe
Why Personality Matters¶
Different contexts need different tones:
- Late at night, things broken: Brief and helpful
- Learning new tool: Detailed and encouraging
- Showing coworker: Professional and clear
- Personal project: Full personality, jokes welcome
wtf adapts to what you need.
