Pace Config

Configure a pace dashboard

Generate a config.yaml for pace from a user's description of what they want to track.

Source of truth: The snippets in this skill are illustrative and may lag behind the running version. Always confirm current shapes with:

pace adapters list
pace adapters explain <type>
pace transforms list
pace transforms explain <type>
pace presets list

Process

0. Check whether a bundled preset already covers the user's request -- see "Start from a preset" below.
1. Ask the user what topics, communities, or content types they care about.
2. Map those interests to adapters (see reference below).
3. Choose sensible params and transforms for each adapter.
4. If multiple adapters feed the same topic, create a pipeline to merge and dedupe them.
5. Design a layout that gives more space to primary interests.
6. If the user wants summaries, filtering by relevance, or interest-based ranking, add LLM config.
7. Write the final config.yaml.
8. Run pace config check config.yaml to validate before handing off to the user.

Start from a preset

Before building from scratch, check whether a bundled preset already matches the user's theme:

pace presets list
# tech-news        -- Tech news: HN + Lobsters frontpage, Lemmy communities, news/blogs, releases
# ml-ai            -- AI and machine learning: arXiv papers, local-LLM community, releases, curated blogs
# daily-brief      -- Morning briefing: world headlines, Wikipedia in-the-news/most-read, big HN stories
# product-launches -- Product launches: Product Hunt, Show HN, trending repos, fresh npm packages
# release-tracker  -- Software release tracking
# academic-papers  -- Academic papers: arXiv, CS theory Q&A, science journalism
# video-podcast    -- Video and podcast content

To use a preset as the starting point:

# Bun:
pace --preset tech-news

# Docker:
docker run -d -p 7453:7453 -v pace-data:/app/data ghcr.io/av/pace:latest --preset tech-news

Guidance: prefer preset + targeted edits when the user's ask matches a theme. Only build from scratch when no preset is close. When using a preset, copy it to config.yaml, make the minimal changes the user requested, and validate with pace config check.

Modifying an existing config

When the user already has a config.yaml:

Example -- "drop YouTube, show only LLM news from HN":

# BEFORE
adapters:
  - type: hackernews
    params:
      feed: top
      limit: 50
  - type: youtube
    params:
      channels: [UCXuqSBlHAE6Xw-yeJA0Tunw]
      limit: 15

# AFTER -- youtube adapter removed; hackernews gains an llm-filter transform
adapters:
  - type: hackernews
    params:
      feed: top
      limit: 50
    transforms:
      - type: llm-filter
        criteria: "relevant to LLM or AI research"

1. Read the current file before making any edits.
2. Make the minimal changes required -- remove/replace adapters the user no longer wants, add new ones, adjust params and transforms.
3. Validate the edited config:

   pace config check config.yaml
   

   This catches schema errors and unknown adapter types without starting the server -- fast iteration loop.
4. Restart required: pace reads config.yaml once at startup; it does not watch the file for changes. After writing the new config, the server must be restarted to pick it up:

   # Bun dev:
   # Ctrl-C, then: bun run dev
   
   # Docker Compose:
   docker compose restart
   
   # Docker direct:
   docker stop <container> && docker run ...
   

5. Immediate panel refresh (after restart): trigger a panel to fetch content right away without waiting for refresh_interval:

   curl -X POST http://localhost:7453/refresh/<panel-id>
   # e.g.: curl -X POST http://localhost:7453/refresh/hackernews
   

Adapter reference

Every adapter has an optional refresh_interval (minutes, default 15, minimum 1) and an optional transforms list applied at ingest time. The name field disambiguates multiple instances of the same type.

hackernews

Hacker News stories.

# Authoritative shape: pace adapters explain hackernews
- type: hackernews
  params:
    type: top          # highest-priority alias (type > feed > stories); top, new, best, ask, show, job
    feed: top          # mid-priority alias; same values. Aliases: newest→new, front→top, askhn→ask, showhn→show, jobs→job
    stories: top       # lowest-priority alias for feed
    limit: 30          # max 200
    min_score: 0       # drop items below this point threshold

rss

Any RSS or Atom feed.

# Authoritative shape: pace adapters explain rss
- type: rss
  params:
    urls:
      - https://example.com/feed.xml
    limit: 50          # max 200; omit for unlimited (per feed)

reddit

Reddit subreddits.

Caveat: Reddit's public unauthenticated .json API often returns HTTP 403 upstream, so this adapter may not work without credentials. Bundled presets omit Reddit for this reason. For community discussions that work out of the box, prefer lemmy (used in tech-news and ml-ai presets).

# Authoritative shape: pace adapters explain reddit
- type: reddit
  params:
    subreddits: [programming, selfhosted]
    sort: hot          # hot, new, top, rising (aliases: popular→hot, trending→rising, best→top)
    limit: 25          # max 100
    min_score: 0
    time: day          # hour, day, week, month, year, all (for sort: top)

github

# Authoritative shape: pace adapters explain github-releases
- type: github-releases
  params:
    repos: [denoland/deno, oven-sh/bun]

  params:
    channels:
      - UCXuqSBlHAE6Xw-yeJA0Tunw   # channel IDs
    playlists: []                    # playlist IDs
    limit: 15                        # max 50

Pipelines

Pipelines merge items from multiple adapters and apply cross-source transforms. Define them when the user wants a combined view.

pipelines:
  - name: combined
    sources: [hackernews, reddit]   # adapter names
    refresh_interval: 15            # optional
    transforms:
      - type: dedupe
        strategy: url
      - type: latest
        count: 40

A panel references a pipeline by using the pipeline name as its source.

Layout

Layout is a recursive flexbox tree. Each node is one of:

• Container (direction + children): row or column flex wrapper.
• Panel (panel + source): content feed panel. Optional display: counter renders stat cards instead of a content list.
• Image widget (image): static image from a URL.
• Text widget (text): static text block (plain, markdown, or html).
• Iframe widget (iframe): embedded external page in a sandboxed iframe.

Panel fields: panel (display name, must be unique), source (required), and optional flex, limit, display, id. source is an adapter name, a pipeline name, or a list of names — a multi-source panel merges items from every listed source into one feed. id pins the panel's storage/refresh identifier (used in POST /refresh/<id>); when omitted it is derived from the panel definition.

layout:
  direction: row           # row or column
  gap: 16px                # optional CSS gap between children
  children:
    - panel: hackernews
      source: hackernews   # adapter name or pipeline name
      flex: 2              # relative size
      limit: 30            # max items to display

    - panel: firehose
      source: [lobsters, mastodon]   # multi-source panel: merged feed from several sources

    - direction: column
      flex: 1
      children:
        - panel: reddit
          source: reddit
        - panel: releases
          source: gh-releases

    - panel: rss
      flex: 1
      source: rss
      limit: 20

Widget nodes

Widgets are layout leaves that display static content (no adapter source needed).

# Image widget
- image: https://example.com/banner.png
  alt: "Dashboard banner"          # optional alt text
  object_fit: cover                # cover, contain, fill, none (default: contain)
  max_height: 200px                # optional CSS max-height
  link: https://example.com        # optional clickable link (https or http://localhost only)
  flex: 1                          # optional relative size

# Text widget
- text: "Welcome to the dashboard"
  format: markdown                 # plain (default), markdown, html
  title: "Greeting"                # optional header
  flex: 1

# Iframe widget
- iframe: https://grafana.example.com/d/abc
  title: "Grafana"                 # optional header
  height: 400px                    # CSS length; takes priority over aspect_ratio
  aspect_ratio: 16/9               # fallback when height is not set (default: 16/9)
  sandbox: "allow-scripts allow-same-origin"  # optional sandbox tokens
  allow: "fullscreen"              # optional Permissions-Policy directives
  flex: 1

Counter display mode

Panels using the counter adapter should set display: counter to render stat cards:

- panel: metrics
  source: my-counter
  display: counter                 # renders stat cards instead of content list

The special source all shows items from every adapter. If layout is omitted entirely, pace renders a single "all" panel as the default.

Below 768px the layout collapses to a single column automatically.

LLM config (optional)

LLM transforms (llm-summarize, llm-filter, llm-rank, llm-merge) pass items through unchanged when the llm block is absent or misconfigured -- they never error out.

# Two concrete provider examples:

# Anthropic (Claude)
llm:
  provider: anthropic
  model: claude-sonnet-4-6
  api_key: ${LLM_API_KEY}
  interests:               # used by llm-rank
    - artificial intelligence
    - typescript

# OpenAI
llm:
  provider: openai
  model: gpt-4o
  api_key: ${LLM_API_KEY}
  interests:
    - artificial intelligence
    - typescript

Wiring the API key:

# Bun dev:
LLM_API_KEY=sk-... bun run dev

# Docker:
docker run -d -p 7453:7453 \
  -e LLM_API_KEY=sk-... \
  -v ./config.yaml:/app/config.yaml:ro \
  -v pace-data:/app/data \
  ghcr.io/av/pace:latest

The provider value is passed to pi-ai; supported providers include anthropic, openai, google, groq, mistral, and others -- see pi-ai docs for the full list.

Optional: timeout_seconds caps each LLM completion (default 120). Raise it for slow local models (e.g. Ollama on modest hardware); a completion that exceeds it is abandoned and the items pass through unchanged.

llm:
  provider: ollama
  model: llama3.1
  api_key: unused
  base_url: http://localhost:11434/v1
  timeout_seconds: 300

Server config (optional)

An optional top-level server block controls server behavior (unknown fields are a validation error):

server:
  base_path: /pace     # serve under a URL prefix behind a reverse proxy (default: none)
  retention_days: 30   # days to keep fetched items in SQLite; 0 disables pruning (default: 30)

• base_path (string): for deployments under a subpath like https://example.com/pace/. Normalized on load (leading / added, trailing / stripped). The server responds at both the prefix and the root, so it works whether or not the proxy strips the prefix.
• retention_days (non-negative integer): items last fetched more than this many days ago are pruned at startup and every 24 hours. 0 keeps everything.

Port and config path are NOT config fields: use --port/$PORT and --config/--preset/$PACE_CONFIG.
