challenge
Presents adaptive codebase challenge questions with multiple-choice and trace exercises. Use when testing contributor knowledge of the codebase.
What this skill does
# Run Gauntlet Challenge
Present challenges from the knowledge base and evaluate answers.
## In-Loop Provider Setup
Before generating a challenge, register the in-loop variation
provider so we do not call out to the Anthropic API just to spawn
a sibling Claude (issue #464). Outside Claude Code this is a
no-op and the default Anthropic provider remains active.
```python
from gauntlet.providers.in_loop import (
register_in_loop_provider_if_inside_claude_code,
)
register_in_loop_provider_if_inside_claude_code()
```
## Steps
1. **Load state**: read `.gauntlet/knowledge.json` and developer
progress
2. **Check for pending challenge**: if
`.gauntlet/state/pending_challenge.json` exists, evaluate the
developer's most recent message as an answer before generating
a new one
3. **Generate challenge**: use adaptive weighting to select a
knowledge entry and challenge type
4. **Present challenge**: show the question with context
5. **Evaluate answer**: score the response (pass/partial/fail)
6. **Record result**: update developer progress and streak
7. **On pass**: write pass token if from pre-commit gate. Show
next challenge if in session.
8. **On fail**: show correct answer with explanation. Present a
new challenge.
## Scoring
| Result | Score | Streak |
|--------|-------|--------|
| Pass | 1.0 | +1 |
| Partial | 0.5 | reset |
| Fail | 0.0 | reset |

IncludedDraws the 12 Houses of the Zodiac Tarot spread to inject entropy into planning when prompts are vague, ambiguous, or casually delegated. Interprets the spread to guide next steps. Use when the user says 'let fate decide', 'YOLO', 'whatever', 'idk', or other nonchalant phrases, makes Yu-Gi-Oh references, or when you are about to arbitrarily pick between multiple reasonable approaches. Prefer over ask-questions-if-underspecified when the user's tone is casual or playful rather than precision-seeking.
