Guided Onboarding

Walk a new developer through the codebase in structured stages.

When NOT To Use

Ad-hoc questions outside a staged path (use gauntlet:challenge)
The knowledge base does not exist yet (use gauntlet:extract)

Stages

|-------|-------|------------|------------|

| 1 | Big picture | architecture, data_flow | 1-2 |

| 2 | Core domain | business_logic | 2-3 |

| 3 | Interfaces | api_contract, data_flow | 3 |

| 4 | Patterns | pattern, dependency | 3-4 |

| 5 | Hardening | error_handling, business_logic | 4-5 |

Steps

Load onboarding progress
Show current stage and progress summary
Present 5 challenges from current stage
Enable hints on first attempt
Track mastery (correct twice = mastered)
Check advancement (80% across 10+ challenges)
Report progress

Graduation

After stage 5, the developer enters the regular gauntlet.

Answer history carries over.

Exit Criteria

[ ] Onboarding progress persists across invocations: current stage

and challenge count survive session restarts and are loaded at

Step 1

[ ] Advancement to the next stage requires 80% correct across 10+

challenges in the current stage; partial completion does not

advance

[ ] Mastery tracking requires correct answers twice for a given

challenge before it is marked mastered

[ ] After Stage 5 completion, the developer's answer history

carries over into the regular gauntlet challenge pool without

loss
