-
-          TODAY'S DATE: ${TODAY}
-
-          STEP 1: Gather today's issues
-          Search for all OPEN issues created today (${TODAY}) using:
-          gh issue list --repo ${{ github.repository }} --state open --search \"created:${TODAY}\" --json number,title,body,labels,state,comments,createdAt,author --limit 500
-
-          IMPORTANT: EXCLUDE all issues authored by Anomaly team members. Filter out issues where the author login matches ANY of these:
-          adamdotdevin, Brendonovich, fwang, Hona, iamdavidhill, jayair, kitlangton, kommander, MrMushrooooom, R44VC0RP, rekram1-node, thdxr
-          This recap is specifically for COMMUNITY (external) issues only.
-
-          STEP 2: Analyze and categorize
-          For each issue created today, categorize it:
-
-          **Severity Assessment:**
-          - CRITICAL: Crashes, data loss, security issues, blocks major functionality
-          - HIGH: Significant bugs affecting many users, important features broken
-          - MEDIUM: Bugs with workarounds, minor features broken
-          - LOW: Minor issues, cosmetic, nice-to-haves
-
-          **Activity Assessment:**
-          - Note issues with high comment counts or engagement
-          - Note issues from repeat reporters (check if author has filed before)
-
-          STEP 3: Cross-reference with existing issues
-          For issues that seem like feature requests or recurring bugs:
-          - Search for similar older issues to identify patterns
-          - Note if this is a frequently requested feature
-          - Identify any issues that are duplicates of long-standing requests
-
-          STEP 4: Generate the recap
-          Create a structured recap with these sections:
-
-          ===DISCORD_START===
-          **Daily Issues Recap - ${TODAY}**
-
-          **Summary Stats**
-          - Total issues opened today: [count]
-          - By category: [bugs/features/questions]
-
-          **Critical/High Priority Issues**
-          [List any CRITICAL or HIGH severity issues with brief descriptions and issue numbers]
-
-          **Most Active/Discussed**
-          [Issues with significant engagement or from active community members]
-
-          **Trending Topics**
-          [Patterns noticed - e.g., 'Multiple reports about X', 'Continued interest in Y feature']
-
-          **Duplicates & Related**
-          [Issues that relate to existing open issues]
-          ===DISCORD_END===
-
-          STEP 5: Format for Discord
-          Format the recap as a Discord-compatible message:
-          - Use Discord markdown (**, __, etc.)
-          - BE EXTREMELY CONCISE - this is an EOD summary, not a detailed report
-          - Use hyperlinked issue numbers with suppressed embeds: [#1234](<https://github.com/${{ github.repository }}/issues/1234>)
-          - Group related issues on single lines where possible
-          - Add emoji sparingly for critical items only
-          - HARD LIMIT: Keep under 1800 characters total
-          - Skip sections that have nothing notable (e.g., if no critical issues, omit that section)
-          - Prioritize signal over completeness - only surface what matters
-
-          OUTPUT: Output ONLY the content between ===DISCORD_START=== and ===DISCORD_END=== markers. Include the markers so I can extract it." > /tmp/recap_raw.txt

-          STEP 1: Gather PR data
-          Run these commands to gather PR information. ONLY include OPEN PRs created or updated TODAY (${TODAY}):
-
-          # Open PRs created today
-          gh pr list --repo ${{ github.repository }} --state open --search \"created:${TODAY}\" --json number,title,author,labels,createdAt,updatedAt,reviewDecision,isDraft,additions,deletions --limit 100

-          This recap is specifically for COMMUNITY (external) contributions only.
-
-
-
-          STEP 2: For high-activity PRs, check comment counts
-          For promising PRs, run:
-          gh pr view [NUMBER] --repo ${{ github.repository }} --json comments --jq '[.comments[] | select(.author.login != \"copilot-pull-request-reviewer\" and .author.login != \"github-actions\")] | length'

-          - copilot-pull-request-reviewer
-          - github-actions
-
-          STEP 3: Identify what matters (ONLY from today's PRs)
-
-          **Bug Fixes From Today:**
-          - PRs with 'fix' or 'bug' in title created/updated today
-          - Small bug fixes (< 100 lines changed) that are easy to review
-          - Bug fixes from community contributors
-
-          **High Activity Today:**
-          - PRs with significant human comments today (excluding bots listed above)
-          - PRs with back-and-forth discussion today
-
-          **Quick Wins:**
-          - Small PRs (< 50 lines) that are approved or nearly approved
-          - PRs that just need a final review
-
-          STEP 4: Generate the recap

 This file is the source of truth for ownership/routing rules.
 
-## Labels
+Assign issues by choosing the team with the strongest overlap. The github-triage tool will assign a random member from that team.
 
-### windows
+Do not add labels to issues. Only assign an owner.
 
-Use for any issue that mentions Windows (the OS). Be sure they are saying that they are on Windows.
+When calling github-triage, pass one of these team values: tui, desktop_web, core, inference, windows.
 
-- Use if they mention WSL too
+## Teams
 
-#### perf
+### TUI
 
-Performance-related issues:
+Terminal UI issues, including rendering, keybindings, scrolling, terminal compatibility, SSH behavior, crashes in the TUI, and low-level TUI performance.
 
-- Slow performance
-- High RAM usage
-- High CPU usage
+### Desktop / Web
 
-**Only** add if it's likely a RAM or CPU issue. **Do not** add for LLM slowness.
+Desktop application and browser-based app issues, including `opencode web`, desktop-specific UI behavior, packaging, and web view problems.
 
-#### desktop
+### Core
 
-Desktop app issues:
+Core opencode server and harness issues, including sqlite, snapshots, memory, API behavior, agent context construction, tool execution, provider integrations, model behavior, documentation, and larger architectural features.
 
-- `opencode web` command
-- The desktop app itself
+### Inference
 
-**Only** add if it's specifically about the Desktop application or `opencode web` view. **Do not** add for terminal, TUI, or general opencode issues.
+OpenCode Zen, OpenCode Go, and billing issues.
 
-#### nix
+### Windows
 
-**Only** add if the issue explicitly mentions nix.
-
-If the issue does not mention nix, do not add nix.
-
-If the issue mentions nix, assign to `rekram1-node`.
-
-#### zen
-
-**Only** add if the issue mentions "zen" or "opencode zen" or "opencode black".
-
-If the issue doesn't have "zen" or "opencode black" in it then don't add zen label
-
-#### core
-
-Use for core server issues in `packages/opencode/`, excluding `packages/opencode/src/cli/cmd/tui/`.
-
-Examples:
-
-- LSP server behavior
-- Harness behavior (agent + tools)
-- Feature requests for server behavior
-- Agent context construction
-- API endpoints
-- Provider integration issues
-- New, broken, or poor-quality models
-
-#### acp
-
-If the issue mentions acp support, assign acp label.
-
-#### docs
-
-Add if the issue requests better documentation or docs updates.
-
-#### opentui
-
-TUI issues potentially caused by our underlying TUI library:
-
-- Keybindings not working
-- Scroll speed issues (too fast/slow/laggy)
-- Screen flickering
-- Crashes with opentui in the log
-
-**Do not** add for general TUI bugs.
-
-When assigning to people here are the following rules:
-
-Desktop / Web:
-Use for desktop-labeled issues only.
-
-- adamdotdevin
-- iamdavidhill
-- Brendonovich
-- nexxeln
-
-Zen:
-ONLY assign if the issue will have the "zen" label.
-
-- fwang
-- MrMushrooooom
-
-TUI (`packages/opencode/src/cli/cmd/tui/...`):
-
-- thdxr for TUI UX/UI product decisions and interaction flow
-- kommander for OpenTUI engine issues: rendering artifacts, keybind handling, terminal compatibility, SSH behavior, and low-level perf bottlenecks
-- rekram1-node for TUI bugs that are not clearly OpenTUI engine issues
-
-Core (`packages/opencode/...`, excluding TUI subtree):
-
-- thdxr for sqlite/snapshot/memory bugs and larger architectural core features
-- jlongster for opencode server + API feature work (tool currently remaps jlongster -> thdxr until assignable)
-- rekram1-node for harness issues, provider issues, and other bug-squashing
-
-For core bugs that do not clearly map, either thdxr or rekram1-node is acceptable.
-
-Docs:
-
-- R44VC0RP
-
-Windows:
-
-- Hona (assign any issue that mentions Windows or is likely Windows-specific)
-
-Determinism rules:
-
-- If title + body does not contain "zen", do not add the "zen" label
-- If "nix" label is added but title + body does not mention nix/nixos, the tool will drop "nix"
-- If title + body mentions nix/nixos, assign to `rekram1-node`
-- If "desktop" label is added, the tool will override assignee and randomly pick one Desktop / Web owner
-
-In all other cases, choose the team/section with the most overlap with the issue and assign a member from that team at random.
-
-ACP:
-
-- rekram1-node (assign any acp issues to rekram1-node)
+Windows-specific issues, including native Windows behavior, WSL interactions, path handling, shell compatibility, and installation or runtime problems that only happen on Windows.
