El agente puede comentar, revisar y etiquetar, pero no puede hacer push. + +## Antes de empezar + +- **Un workspace encendido con las herramientas de tu repositorio.** El agente ejecuta los tests en uno de tus [workspaces](/es/docs/workspaces), así que necesita lo mismo que tu CI: Go, Node, Python... Instálalas una vez en el workspace, como lo harías en tu portátil, y mantenlo encendido: un workspace parado no puede lanzar runs, y los eventos que llegan mientras tanto se pierden.

Elige la plantilla **Pull request review**: viene con instrucciones, el filtro del webhook de GitHub y una fila de secreto `GITHUB_TOKEN` preparada. + + + +El editor tiene una tarjeta por tema.

El clon, la instalación de dependencias, los tests y la review lo comparten. Súbelo si tus tests son lentos. + +### Repositorio + + + +- **GitHub repository (optional)**: `owner/name` del repositorio que comprueba y en el que comenta. +- **Checkout**: **Fresh clone per run**. Antes de que arranque el agente, NaN clona el repositorio en el commit exacto del push, en una carpeta que solo usa ese run, y la borra, cachés incluidas, cuando termina el run, pase lo que pase. El agente no puede hacer push desde ahí, que es lo que necesita un revisor. Consulta [Clon nuevo por run](/es/docs/automations#clon-nuevo-por-run). +- **Run pull requests from forks and outside contributors**: déjalo desactivado. El agente ejecuta el código de la pull request junto a sus secretos, así que las pull requests de forks y de autores sin permiso de escritura se ignoran. Consulta [por qué](/es/docs/automations#pull-requests-de-forks-y-de-colaboradores-externos). +- **Keep one comment per pull request**: activado. El primer run publica el comentario y los siguientes lo editan. Consulta [Un comentario por pull request](/es/docs/automations#un-comentario-por-pull-request). + +### Secretos + + + +Cada fila tiene tres campos: el secreto guardado, el nombre de variable con el que lo ve el run y quién lo recibe. La plantilla añade una fila `GITHUB_TOKEN`. Elige en ella `GITHUB_WRITE_TOKEN`, con **Actions only (write access)**. Para un repositorio privado, pulsa **Add a secret** y añade `GITHUB_READ_TOKEN` como `GITHUB_TOKEN`, con **Agent (read access)**: NaN lo usa para clonar. Las dos filas usan el nombre de variable `GITHUB_TOKEN`, cada una para su destinatario. + +### Aprobación + + + +Elige **Fully automatic**. El editor te avisa de que los eventos de fuera pueden hacer que la automatización actúe sin preguntar: aquí es justo lo que buscas, y con un clon nuevo el agente solo puede comentar, revisar y etiquetar. Si quieres una red de seguridad, elige **Custom** y deja sin marcar solo **Comment on pull requests**: cualquier otra cosa que proponga te espera en **Needs approval**. + +### Límites + + + +- **When a run is active**: **Cancel the previous run**. La plantilla viene con **Skip the new event**, que seguiría revisando un commit viejo mientras subes otros nuevos. Con cancelar, un push cancela la review de la misma pull request que sigue en marcha, y solo el último commit recibe comentario. Las demás pull requests no se ven afectadas. Consulta [Cuando ya hay un run activo](/es/docs/automations#cuando-ya-hay-un-run-activo). +- **Runs per hour**: 30 por defecto. Súbelo para un repositorio con mucho movimiento, hasta 120. + +### Las instrucciones + +Las instrucciones son de confianza: son tuyas. El evento que lanza un run (la pull request, su título y su descripción) llega al agente como datos, nunca como instrucciones. Adapta las comprobaciones a tu repositorio y pega esto en **Instructions** (en inglés, como el comentario que escribe el agente): + +```text +You are the PR gatekeeper for this repository.

La respuesta de la API ([`GET /v1/automations/{id}/deliveries`](/es/docs/api#tag/automations)) también trae un `reason` para las entregas ignoradas: `event_filter` (el filtro de eventos no coincidió), `actor_filter` ([solo algunos usuarios de GitHub](/es/docs/webhooks#solo-algunos-usuarios-de-github)), `untrusted_head` (un fork o un autor de fuera), `ping` o `filter_invalid`. + +## Lo que cuesta + +Cada review es un run en tu workspace, y los tokens que usa su agente cuentan para tu plan como cualquier otra petición. Nuestras reviews de un repositorio de Go de tamaño medio tardan de 8 a 20 minutos; la de las capturas usó 430K tokens de entrada y 5K de salida. Casi todo es el agente leyendo código y la salida de los tests, así que un repositorio pequeño cuesta mucho menos. El run de aplicación no usa inferencia. + +Algunas cosas lo mantienen a raya: + +- **Cancel the previous run** hace que una ráfaga de push cueste una review, no una por push. +- **Runs per hour** pone un tope a la automatización (30 por defecto). +- Las reviews comparten los [límites de todos los runs](/es/docs/runs#cuántos-runs-a-la-vez): cuántos trabajan a la vez en el workspace y en todos tus workspaces juntos. Las pull requests que llegan mientras está ocupado esperan en la cola. +- Los borradores se ignoran hasta que están listos para revisar. + +La lista completa está en [Límites](/es/docs/automations#límites). + +## Ideas para adaptarlo + +Las mismas piezas (un webhook de GitHub, un clon nuevo, instrucciones, una acción propuesta) sirven para otras automatizaciones. Algunas ideas: + +- **Tus propias comprobaciones.** Cambia la lista: migraciones con su rollback, entradas en el changelog, cambios de API pública documentados, cabeceras de licencia, tamaño del bundle. El formato del comentario no cambia. +- **Etiquetas en vez de comentarios.** Pide `github_add_labels` con `needs-tests` o `ready-for-review`, para que tu tablero muestre el estado de un vistazo. +- **Una review en vez de un comentario.** `github_pr_review` con `COMMENT` o `REQUEST_CHANGES`. Deja **Approve** para una persona: elige la aprobación **Custom** y deja **Review pull requests** esperándote. +- **Triaje de issues.** La plantilla **Issue triage** analiza las issues nuevas y sus comentarios, y propone etiquetas. +- **Fallos de CI.** La plantilla **CI failure** investiga las ejecuciones de workflow fallidas y propone un arreglo o una explicación. + +
+ +No: una automatización actúa sobre un solo **GitHub repository**. Crea una por repositorio, como hacemos nosotros. Pueden compartir el workspace, las instrucciones y los tokens, siempre que cada token cubra los repositorios en los que se usa. + +
+ +
+ +No. Ejecuta los tests para comprobar la pull request, pero lo que protege la rama principal sigue siendo el CI. El gatekeeper añade lo que el CI no comprueba: si los tests corresponden a lo que dice la pull request, y una primera review. + +

A pull request pushed ten times still has one comment, with the latest result. +- **Only the latest commit is reviewed.** A push while a review is running cancels that review and starts a new one. +- **Each review gets its own copy of the code**, at the exact commit of the push, and NaN deletes it with all its caches when the review ends. +- **Nothing to approve.** The comment is posted on its own. The agent can comment, review and label, but it cannot push. + +## Before you start + +- **A running workspace with your repository's toolchain.** The agent runs the tests in one of your [workspaces](/docs/workspaces), so it needs what your CI needs: Go, Node, Python... Install them once in the workspace, as you would on your laptop, and keep it running: a stopped workspace cannot start runs, and the events that arrive meanwhile are lost. The example uses a workspace called `work` with Go installed. +- **Pi or Hermes installed in that workspace**, from its [Software panel](/docs/workspaces#agents-and-the-software-panel). The example uses Pi. +- **A plan with inference.** Each review is an [agent run](/docs/runs) and uses your plan like any other request. +- **Admin access to the repository on GitHub**, to add the webhook and create the tokens. +- **A browser sign-in at [cloud.nan.builders](https://cloud.nan.builders/)**, with the email link: creating automations and saving secrets need it. + +## Save your GitHub tokens + +The automation needs to do two things on GitHub: clone the repository, if it is private, and post the comment. Use one token for each, both [fine-grained personal access tokens](https://github.com/settings/personal-access-tokens/new) limited to that one repository. In GitHub's form, under **Repository access**, choose **Only select repositories** and pick it, and set an expiration date. + +| Name to save it as | Permissions | Who receives it | +|---|---|---| +| `GITHUB_WRITE_TOKEN` | **Contents** read, **Pull requests** read and write | Only the step that posts the comment. The agent never sees it. | +| `GITHUB_READ_TOKEN` | **Contents** read | The agent, to clone. Never give it write permissions. | + +A public repository does not need the read token. + +Save both on the portal, with these names: your settings, **Secrets**, **Add secret**. A secret is write-only: once saved, nobody can read it back, not even you. See [Add a secret](/docs/automations#add-a-secret). + + +The agent runs the code of the pull request, tests included, and it can read every secret it receives. A test could try to send that token somewhere. Keep the token that can write out of the agent's hands: give it the read-only one, and let NaN post the comment with the other. Our own setup in the screenshots uses a single token for both rows; two tokens are the safer choice. + + +## Create the automation + +Open **Automations** on the portal and press **New automation**. Pick the **Pull request review** template: it comes with instructions, the GitHub webhook filter and a `GITHUB_TOKEN` secret row ready. + + + +The editor has one card per topic. These are the values of our gatekeeper, card by card. + +### What the agent does + + + +- **Name**: something you recognise in a list, for example `PR gatekeeper: owner/name`. +- **Instructions**: replace the template's text with the [instructions below](#the-instructions), adapted to your repository. +- **Workspace** and **Agent**: the workspace with your toolchain, and the agent installed in it. +- **Time limit (minutes)**: 30 is enough for a mid-sized Go or Node repository. The clone, installing dependencies, the tests and the review share it. Raise it if your test suite is slow. + +### Repository + + + +- **GitHub repository (optional)**: `owner/name` of the repository it checks and comments on. +- **Checkout**: **Fresh clone per run**. Before the agent starts, NaN clones the repository at the exact commit of the push into a folder only that run uses, and deletes it, caches included, when the run ends, whatever happens. The agent cannot push from it, which is what a reviewer needs. See [Fresh clone per run](/docs/automations#fresh-clone-per-run). +- **Run pull requests from forks and outside contributors**: leave it off. The agent runs the code of the pull request next to its secrets, so pull requests from forks and from authors without write access are ignored. See [why](/docs/automations#pull-requests-from-forks-and-outside-contributors). +- **Keep one comment per pull request**: on. The first run posts the comment and every later run edits it. See [One comment per pull request](/docs/automations#one-comment-per-pull-request). + +### Secrets + + + +Each row has three fields: the saved secret, the variable name the run sees it as, and who receives it. The template adds a `GITHUB_TOKEN` row. Pick `GITHUB_WRITE_TOKEN` in it, with **Actions only (write access)**. For a private repository, press **Add a secret** and add `GITHUB_READ_TOKEN` as `GITHUB_TOKEN`, with **Agent (read access)**: NaN uses it to clone. Both rows use the variable name `GITHUB_TOKEN`, each for its own receiver. + +### Approval + + + +Choose **Fully automatic**. The editor warns you that outside events can make the automation act without asking: that is the point here, and the agent can only comment, review and label with a fresh clone. If you want a safety net, choose **Custom** and leave only **Comment on pull requests** unticked: anything else it proposes waits for you in **Needs approval**. + +### Limits + + + +- **When a run is active**: **Cancel the previous run**. The template comes with **Skip the new event**, which would keep reviewing an old commit while you push new ones. With cancel, a push cancels the review of the same pull request that is still running, and only the latest commit gets a comment. Other pull requests are not affected. See [When a run is already active](/docs/automations#when-a-run-is-already-active). +- **Runs per hour**: 30 is the default. Raise it for a busy repository, up to 120. + +### The instructions + +The instructions are trusted: they are yours. The event that starts a run (the pull request, its title and body) reaches the agent as data, never as instructions. Adapt the checks to your repository and paste this into **Instructions**: + +```text +You are the PR gatekeeper for this repository. A pull request was opened or +updated (see the event in the input). Check that it meets the team's minimum +bar and report the result as ONE comment on the pull request. + +## 1.

An agent that clones again wastes time and could review the wrong commit. +- **It spells out the proposal.** NaN tells every automation's agent how to propose actions; writing the exact `actions.json` makes the result predictable. `$NAN_RUN_ARTIFACTS` is the folder for the run's files, and `body_artifact` points at the comment as `artifacts/`. +- **It always proposes the comment**, also when everything passes. With one comment per pull request, a green result replaces an old red one. +- **It treats the pull request as data.** Anyone who can open a pull request can write in its body; the last paragraph keeps the agent on your instructions. + +Press **Create automation**. It appears in your list, with its template, agent, workspace, repository and approval mode: + + + +## Connect GitHub + +The automation runs when GitHub tells it a pull request changed.

The run starts within seconds. + +### The run + +The **Runs** tab of the automation lists its runs, newest first. A webhook run shows what it checked out (`fresh @` and the commit) and the pull request.

With **Fully automatic**, it says it was applied without approval: + + + +Further down, **Applying the actions** links the **apply run**: a separate step, with no agent, that posts the comment with your **Actions only** token. **View on GitHub** takes you to the comment: + + + +The review run ends as **Succeeded** as soon as its proposal is accepted, before the comment is posted. Whether the comment made it to GitHub is in the apply run. + +## Push again + +Fix what the comment asks for and push. The webhook sends `synchronize`, a new run reviews the new commit, and its apply run **edits** the same comment. The pull request keeps one comment, with the latest verdict: this is how our ❌ turned into ✅. + +If you push again while a review is still running, that review is cancelled and the new commit gets its own. The cancelled run shows **Superseded by run** and a link to the new one: + + + +A superseded run never posts anything: if its agent had already finished, its proposal is dropped, so an outdated review never reaches the pull request. + +## Troubleshooting + +Start with the **Deliveries** tab: it lists every webhook the automation received in the last 30 days, what happened with it and the run it started. + + + +| What you see | Why | What to do | +|---|---|---| +| No delivery at all | GitHub did not send it, or sent it somewhere else. | In GitHub, **Settings**, **Webhooks**, open the webhook and check **Recent Deliveries**. `401`: the secret does not match, paste it again or rotate it in NaN. `404`: wrong URL, or the trigger is paused. `415`: the content type is not `application/json`. | +| **Ignored by a filter** for every event | The event is not a pull request event, the pull request is a draft, or it is the `ping`. | Check that GitHub sends **Pull requests** and that the pull request is ready for review. | +| **Ignored by a filter** for one pull request | With **Fresh clone per run**, pull requests from forks or from authors without write access are ignored. | Expected. If you trust them, see [Pull requests from forks and outside contributors](/docs/automations#pull-requests-from-forks-and-outside-contributors). | +| **Not accepted: your membership does not include runs** | Your plan has no inference, the workspace is stopped, or its agent is not installed. GitHub does not retry it, so that event is lost. | Start the workspace and push again. | +| **Skipped: a run for the same subject is active** | **When a run is active** is still **Skip the new event**. | Set it to **Cancel the previous run**. | +| The run failed early, during the checkout | It could not clone: a private repository without a read token, or a token without access to it. | Add `GITHUB_READ_TOKEN` as `GITHUB_TOKEN` with **Agent (read access)**. The log says why. | +| The run failed with `proposal_invalid` | The proposal was not valid: a push (refused with a fresh clone), a malformed `actions.json`, or a `body_artifact` that is not `artifacts/` for a file the agent wrote. | Check **Output** and the files of the run. Ask for exactly the `actions.json` in the instructions above. | +| The run timed out | The tests took longer than the **Time limit (minutes)**. | Raise it, or ask the agent to run only the tests related to the changed files. | +| Run **Succeeded**, no comment | The comment is posted by the apply run, which failed (`action_failed`). | Open the apply run: usually the write token lacks **Pull requests** write, or expired. | +| A new comment on every push | **Keep one comment per pull request** is off, or the token is a GitHub App installation token. | Turn it on and use a personal access token. | + +From the terminal, `nan automations deliveries ` shows the same list. The API answer ([`GET /v1/automations/{id}/deliveries`](/docs/api#tag/automations)) also carries a `reason` for ignored deliveries: `event_filter` (the event filter did not match), `actor_filter` ([only some GitHub users](/docs/webhooks#only-some-github-users)), `untrusted_head` (a fork or an outside author), `ping` or `filter_invalid`. + +## What it costs + +Each review is a run in your workspace, and the tokens its agent uses count against your plan like any other request. Our reviews of a mid-sized Go repository take 8 to 20 minutes; the one in the screenshots used 430K input tokens and 5K output tokens. Most of it is the agent reading code and test output, so a small repository costs far less. The apply run uses no inference. + +Some things keep it in check: + +- **Cancel the previous run** means a burst of pushes costs one review, not one per push. +- **Runs per hour** caps the automation (30 by default). +- Reviews share the [limits of every run](/docs/runs#how-many-runs-at-once): how many work at once in the workspace, and in all your workspaces together. Pull requests that arrive while it is busy wait in the queue. +- Drafts are ignored until they are ready for review. + +The full list is in [Limits](/docs/automations#limits). + +## Ideas to adapt it + +The same pieces (a GitHub webhook, a fresh clone, instructions, one proposed action) make other automations. Some ideas: + +- **Your own checks.** Swap the checklist: migrations that come with a rollback, changelog entries, public API changes documented, licence headers, bundle size. The comment format stays the same. +- **Labels instead of comments.** Ask for `github_add_labels` with `needs-tests` or `ready-for-review`, so your board shows the state at a glance. +- **A review instead of a comment.** `github_pr_review` with `COMMENT` or `REQUEST_CHANGES`. Keep **Approve** for a human: choose **Custom** approval and leave **Review pull requests** waiting for you. +- **Issue triage.** The **Issue triage** template analyses new issues and their comments, and proposes labels. +- **CI failures.** The **CI failure** template investigates failed workflow runs and proposes a fix or an explanation. + +
+ +No: an automation acts on one **GitHub repository**. Create one per repository, as we do. They can share the workspace, the instructions and the tokens, as long as each token covers the repositories it is used on. + +
+ +
