tour

An interactive guide for a new engineer learning an existing codebase. It introduces the system one part at a time and asks questions during the walkthrough.

In plain words
What is it for?
Use it to get an onboarding tour, understand the entry point and modules, and learn how the project's technology and data-persistence rules work.
Why use it?
It avoids overwhelming newcomers with the entire architecture and checks their understanding before revealing more detail.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

tour scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Draft Tour: Interactive Onboarding

Provide an interactive codebase walk-through based on existing architecture and guardrail constraints.

Red Flags - STOP if you're

  • Dumping the entire architecture.md into the chat window.
  • Giving answers to foundational pattern questions before prompting the developer to guess.
  • Explaining code the developer hasn't explicitly asked to view yet.

Execution Constraints

  1. Load Context: Read draft/architecture.md, draft/tech-stack.md, and draft/guardrails.md.
  2. Interactive Cadence: Ask the developer if they are familiar with the tech stack constraints found in draft/tech-stack.md.
  3. Module Introduction: Instead of listing all modules, introduce the "Entry Point" module first.
  4. Active Challenge: After explaining a module's responsibility, challenge the developer: "Based on our Context-Driven Development rules, how do you think we handle data persistence here?" Wait for their answer before revealing the architecture strategy.
    • If the answer is correct, confirm briefly and cite the supporting line in architecture.md / guardrails.md.
    • If the answer is partially right, name what they got right, then ask a narrower follow-up (e.g., "Right that we cache reads — what's the invalidation trigger?") before revealing the rest.
    • If the answer is wrong, do not just hand them the answer. Quote the specific guardrail or HLD section that contradicts it, then re-prompt with a hint scoped to that section.
  5. Traceability: Highlight draft/.state/facts.json showing how module constraints have evolved.
  6. Track Lifecycle Walk: Show the full feature lifecycle and who owns each gate:
    • /draft:new-trackspec.md (requirements + classification + approvers) + plan.md (phases/tasks)
    • /draft:decomposehld.md (always, with graph-derived diagrams) + lld.md (when --lld or High-complexity module)
    • Approvers (HLD): Technical Leads, Architecture Review Board, Cloud Operations (SaaS), QA Leads (on-prem), PM Leads
    • Approvers (LLD): Team Leads, Technical Leads, Quality Assurance
    • /draft:implement → TDD loop reading lld.md/hld.md for stub generation
    • /draft:upload → blocks git upload for high/mission-critical tracks until HLD §Approvals signed
    • /draft:deploy-checklist → blocks deploy until HLD §Checklist + LLD §Alerting Thresholds populated
    • Walk a real example track from draft/tracks/ if any exist; otherwise sketch a hypothetical low-criticality flow.
  7. Completion: Guide the developer to create their first test track using /draft:new-track so they understand the artifact loop end-to-end.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

tour is a skill published in the GitHub repository drafthq/draft (40 stars, last pushed 15d ago), licensed MIT. It adds 31 tokens to every session and 647 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
