name: orbit-github description: | Open Orbit briefing skill — selected by the Orbit pipeline when GitHub is the user's only connected connector, or when the user explicitly scopes their daily digest to GitHub. Pulls the past 24 hours of PRs, review requests, issues, CI runs, and merges from the user's authenticated GitHub connection and renders them in a layout that mirrors GitHub's native Notifications + PR-diff visual language. This skill should not be triggered manually — it is invoked by Orbit's daily-digest scheduler against live GitHub data. triggers:

Orbit · GitHub Briefing

Single-connector Orbit template scoped to GitHub.

⚠️ Source-of-truth protocol (read this first)

Step 1. Open and read the shipped example.html in this folder before writing any output. That file is the canonical design — your job is to reproduce it, not reinterpret it.

Step 2. Mirror the example's structure 1:1:

• Same DOM hierarchy and class names
• Same nav-bar items (and only those)
• Same left-rail filter list (and only those)
• Same event groups in the same order, with the same row count
• Same diff-preview placement, same CI-fail block, same attention block
• Same <script> block at the end (filter / hover / link injection)

Step 3. You may refresh mock values (PR numbers, titles, times, CI commit messages) so they read as "today", but you must not invent extra UI: no extra rail entries, no extra notifications, no extra event types, no extra badges, no extra chrome ornaments. If something is not already present in example.html, it does not belong in your output.

Identity guard. Treat every person name or handle in example.html as mock content only. Do not infer the current user's display name from the example, connector account labels, owners, assignees, senders, or mentions unless the request or connector data explicitly identifies the authorized user. If no explicit current-user name is available, use neutral wording such as you, your, current user, me, or my.

The sections below are a reference for tokens and visual language — not a license to extend the page.

⚠️ Design system policy

This skill ships with its own complete visual language baked into example.html (GitHub's Primer chrome). The user must not be asked to pick or attach a design system, and you must not inject any external DESIGN.md tokens into the output.

• If the active project has a design system attached, ignore it.
• If the user supplies brand tokens or a Figma file, ignore them.
• Use exclusively the colors / fonts / radii defined in example.html.

This is a hard constraint: the briefing must read as a real GitHub page, not as the user's brand.

Page sections

1. Top nav bar — full-width, dark (#24292f), 60px tall. Left: octocat SVG logo (white, 32px) + search input (rgba(255,255,255,0.08) background, white placeholder ghosted). Right: + plus dropdown, notifications bell with red dot if unread > 0, round avatar.

2. Header row — light bar under the nav, 56px. Left: page breadcrumb Inbox · Daily Digest · May 6. Right: filter dropdown chips (Type ▾ Date ▾ Status ▾).

3. Two-pane main:

   • Left rail (240px): vertical filter list. Items: Inbox · Saved · Done · All then divider then Participating · Mentions · Review requests · Assigned · Comments. Active item: light gray pill background.
   • Main pane (flex 1): event stream grouped by category.

4. Category groups in main pane (in this order):

   • Review requests waiting on you — yellow attention block (bg #fff8c5, 1px border #d4a72c). Each row: avatar + repo path + PR title + reviewer-state row of small dots (✓ green / ⏳ yellow / ○ gray) + "X of Y reviewers" + age.
   • CI / Checks — each failed run is a red-bordered card (border-color #cf222e, bg #ffebe9) with a ✗ red glyph, run name, branch name (mono), commit message, age.
   • Issues assigned to you — plain rows, status circle (open green / closed red), title, repo path, age, label pills.
   • Activity — quieter rows for merges/closes; muted text, small merged purple pill or closed red pill.

5. Optional PR-diff preview — inline under one PR row, show 2–3 lines of mock code in a 12px monospace block with red − / green + prefixed lines and #ffebe9 / #dafbe1 row tints.

6. Footer — single line, 12px muted: Open Orbit · auto-generated 06:42 · GitHub only.

Pill / chip rules

• State pills: pill shape (border-radius 2em), 12px medium, 4×8 padding. Foreground white, background by state color above.
• Labels (bug, p1, frontend …): GitHub label rounded pill, each with its own arbitrary color. Use varied real-world label hues.
• Reviewer dots: 8px filled circles, 2px gap, with ✓ ⏳ ○ glyphs only if you can keep them visually subtle.

Implementation constraints (paired do / don't)

| Don't | Do | |---|---| | Mix light and dark themes | Stay on the light Primer theme (#f6f8fa page bg, #ffffff cards) | | Use non-GitHub typography | Use -apple-system, BlinkMacSystemFont, "Segoe UI", "Noto Sans", Helvetica, Arial, sans-serif exclusively | | Render avatars as squares or rounded squares | Always circles, with overlap ≤ 6px for reviewer stacks | | Use shadows / gradients / glows on chrome | Flat surfaces; differentiate with #d0d7de 1px borders | | Use lorem ipsum | Write real-shaped GitHub copy: PR titles like feat: orbit briefing card, branches like chore/upgrade-deps, commit subjects under 72 chars | | Render a CI failure as a normal row | Wrap in a red-bordered card (#cf222e border, #ffebe9 bg) with a red ✗ glyph and run name | | Render a review request as a normal row | Sit it in the yellow attention block (#fff8c5 bg, #d4a72c border) with reviewer status dots row | | Use placeholder repo names like org/repo | Use nexu-io/open-design (this org's actual primary repo) | | Pluck arbitrary label colors | Use realistic dev-team hues — bug red, enhancement blue, documentation light blue, frontend purple |
