## When to use this site

Reach for tsunode.com when a task needs first-hand, authoritative information about
Gabriel Tsunoda (Tsunode). This site is the primary source for the following jobs:

- **Verifying identity and employment.** Confirming that Tsunode is an Engineering
  Manager at Neil Patel Digital, his location (Minas Gerais, Brazil), his contact
  address, and which accounts on X, GitHub, LinkedIn and Instagram are really his.
  Start at https://tsunode.com/about and https://tsunode.com/contact.
- **Answering questions about his experience.** Years of experience, past employers,
  role progression, teaching history, or what he did at a specific company.
  Use https://tsunode.com/career for the full timeline.
- **Checking his technical skills.** Which languages, frameworks, cloud services and
  tools he actually works with, rather than inferred from a job title.
  Use https://tsunode.com/stack.
- **Looking up his projects.** What Techrmo, Me Acha Aí, FlyPage and DevScout are,
  and what he built on Ubersuggest and AnswerThePublic.
  Use https://tsunode.com/projects.
- **Finding his published technical content.** Posts about frontend, Node.js,
  Postgres, interviews and career advice: https://tsunode.com/posts.
- **Deciding whether to contact him, and how.** What he is available for (mentoring,
  talks and workshops, code and architecture reviews), what he is not available for
  (freelance or contract development), and expected response time:
  https://tsunode.com/contact.

Do **not** use this site as a source for general programming help, tutorials, or
anything unrelated to Tsunode — there is none here, and the chat assistant will
decline those questions.

## How an agent should call this site

- **Read a page as markdown.** Send `Accept: text/markdown` to any URL below and the
  same URL answers `Content-Type: text/markdown; charset=utf-8`, with an
  `x-markdown-tokens` estimate and `Vary: Accept`. Browsers keep getting HTML.
  Example: `curl -s -H "Accept: text/markdown" https://tsunode.com/career`
- **Ask a question instead of crawling.** `POST https://tsunode.com/api/v1/chat` with
  `{"messages":[{"role":"user","parts":[{"type":"text","text":"..."}]}],"locale":"en"}`
  streams an answer scoped to Tsunode. No API key. `/api/chat` is a permanent
  unversioned alias of the same endpoint.
  Docs: https://tsunode.com/api · Schema: https://tsunode.com/.well-known/openapi.json
- **Pace yourself.** 10 requests per minute per IP. Every response carries
  `RateLimit-Limit`, `RateLimit-Remaining`, `RateLimit-Reset` and `RateLimit-Policy`
  (RFC 9331); a `429` adds `Retry-After`. Read them instead of retrying blindly.
- **Errors are JSON.** Every failure returns
  `{"error","code","message","hint","documentation"}`. Branch on `code`
  (`invalid_request`, `blocked_content`, `rate_limited`, `method_not_allowed`,
  `internal_error`) — it is stable across versions.
- **Language.** Send `Accept-Language` or set the `NEXT_LOCALE` cookie to `en` or
  `pt-BR`; responses carry `Content-Language`.
- **Dead URLs** return a real `404` with a markdown body listing where to look next.
