Mohamed BoudraandGitHub dfd18a44a7 Document Hub and let docs pages nest (#2864)
* feat(website): nest docs pages under landable groups

The docs sidebar could already render groups from subdirectories in
public-docs, but nothing used it because every doc was a flat file, and
two things stopped it being usable.

A group had no page of its own, so its label was only a toggle and its
name came from the directory name via formatLabel. A directory's
index.md now supplies the group's label, order, and href, which makes
the group landable and lets the label be authored rather than derived.

Categories and top-level directories named the same thing, so a
categorised doc at hub/index.md produced a group nested inside its own
category. Only directories below the top level become groups now.

Also fixes two behaviours in the sidebar:

- The open/closed effect assigned containsActive on every change, so a
  group you expanded to browse collapsed the moment you navigated
  anywhere else. Navigating in now opens a group and navigating away
  leaves it alone.
- The sidebar scrolls independently of the page and never scrolled the
  active entry into view, so loading or refreshing a page far down the
  list left the sidebar parked at the top with no visible position.

The group row is a single target: it navigates and expands, and
collapses when clicked again from the page it points at. A separate
chevron button would put two actions a few pixels apart.

* docs(hub): document Hub

Adds a Hub section covering what it is, how it works, daemons,
triggers, configuration, activity, and the two ways to run it.

The section separates using Hub from running it. Overview, quickstart,
daemons, triggers, and configuration hold regardless of who operates
the deployment; the self-hosting branch owns deploying the service and
creating the GitHub, Slack, and Discord apps it talks to. That split
falls on a real seam, because those apps are exactly what a hosted Hub
would own on your behalf. Hosted is a placeholder until it ships.

Each provider gets a trigger page carrying its events, filter
semantics, and the full paseo.event.* reference for the data a prompt
can read. That data is the thing a config author actually needs and
the thing they cannot get from anywhere else.

Every YAML block was parsed against the Hub config schema rather than
eyeballed, which kept several plausible-looking things out of the
docs: worktree prNumber takes a literal number and not a merge
variable, only daemon environments run today, and github.push has no
actor so it can never satisfy the required from_users filter.

Troubleshooting moves to order 90 so it stays last.

* refactor(website): let the active docs entry scroll itself into view

The layout queried the sidebar for the active entry after every
navigation, which coupled it to when that entry mounts. A link inside a
collapsed group only mounts once the group's own effect opens it, so
the query could run against a DOM that does not contain it yet.

Moving the scroll to the entry removes the ordering question rather
than answering it, and drops the ref and the cross-component query.

Reported by Greptile on #2864. The failure it described does not
reproduce: navigating from a page outside a collapsed group into one of
its children still scrolls correctly, verified with the group confirmed
collapsed and the sidebar forced to the top. The coupling was real even
though the bug was not.

* docs(hub): stop listing BETTER_AUTH_URL as required

It falls back to PASEO_CLOUD_PUBLIC_URL, so a deployment that sets the
public origin already has a correct auth base URL. Listing it as
required made the Fly recipe look incomplete when it was not.

Moved to optional with its default, and recorded what actually breaks
without BETTER_AUTH_SECRET: the auth routes close and nobody can sign
in.

Reported by Codex on #2864, which read the same inconsistency the other
way round and proposed adding the variable to the Fly example.

* docs(hub): attach a database in the Fly recipe

The Fly section showed inline config and a secrets command, neither of
which supplied DATABASE_URL. It defaults to localhost:5432, which on
Fly reaches nothing, so the documented deployment could not start.

fly postgres attach sets DATABASE_URL as a secret, so the step is the
attach itself rather than another variable to copy.

Reported by Codex on #2864.

title: Hub triggers description: How Hub matches an inbound event to a trigger: events, filters, and the allowlist that gates every execution. nav: Triggers order: 64 category: Hub

Triggers

A trigger says: when this event arrives, from this source, from these people, run this agent with this prompt.

triggers:
  - name: mention
    on: github.issue_comment
    environment: dev
    filters:
      repo: acme/api
      contains: "@paseo"
      from_users: [alice]
    agent:
      provider: codex
      mode: full-access
    prompt: ${{ paseo.event.github.comment.body }}

Field-by-field detail is in the hub.yml reference. This page covers matching.

Events

on Fires when
github.issue_comment A comment on an issue or pull request
github.issues An issue is opened or edited
github.pull_request_review A review is submitted
github.pull_request_review_comment A comment on a diff
slack.mention The bot is mentioned in a channel
discord.mention The bot is mentioned in a guild
manual.run A run started from the API

Each provider page documents its events and the data they expose:

Filters

filters is required, and from_users must be present and non-empty. A trigger without it is rejected at validation.

The allowlist is what keeps a stranger's comment on a public issue from starting an agent on your machine. There is no default, because a safe default differs per repository.

Filter Applies to Matches
from_users all GitHub: login. Slack and Discord: user id, not display name
repo GitHub owner/name
workspace Slack Team id, T01234567
guild Discord Guild id
channels Slack, Discord Channel ids
contains all Substring of the message text
pattern all Prefix of the message text
connection all A connection slug, when the organization has several

All conditions must pass. There is no any mode.

Which connection an event comes from

repo, workspace, and guild are resolved to immutable ids when the configuration activates, along with the connection that owns them. Naming a resource the organization has no connection for fails activation, so you find out on push rather than when someone comments.

Omit the resource filter and the trigger listens to every connection of that provider in the organization. To pin it to one:

filters:
  connection: acme-github
  from_users: [alice]

See How Hub works for what activation compiles.

When two triggers match

Both run. Triggers are not ordered and do not shadow each other, in one configuration or across projects.

Replying

allow_outputs gives the agent a single-use reply tool for the conversation that triggered it:

allow_outputs:
  - type: slack.reply

Only slack.reply and discord.reply exist. GitHub-triggered agents reply with the scoped GH_TOKEN they already have, so gh issue comment works.
