Identifying the owning team

Use the canonical owners script at .github/scripts/owners.mjs. It parses .github/OWNERS with last-match-wins semantics and returns allocations sorted by file count with a share percentage. Using the script keeps this skill consistent with whatever CI uses.

1. Write the PR's changed file paths (from the files list) to a temp file, one per line:

   printf '%s\n' <path1> <path2> ... > /tmp/pr-<number>-files.txt

2. Run the script:

   node .github/scripts/owners.mjs /tmp/pr-<number>-files.txt

3. The script prints JSON of the form:

   {
     "totalFiles": 12,
     "allocations": [
       { "team": "@n8n-io/ai", "fileCount": 10, "share": 83, "files": [...] },
       { "team": "@n8n-io/catalysts", "fileCount": 2, "share": 17, "files": [...] }
     ]
   }

   Allocations are already sorted by fileCount descending — take the first entry as the winning team.
4. Clean up: rm /tmp/pr-<number>-files.txt.
5. Strip the @n8n-io/ prefix from allocations[0].team — the GitHub team slug is nodes, iam, ai, etc. If allocations is empty (no file matched any rule, which is possible only if .github/OWNERS lost its catch-all), fall back to catalysts.
6. Map the GitHub team slug to its Linear team name and PR label using the table below. The team field in the JSON output is the Linear team name. If the resolved GitHub team slug has no entry in the table, fall back to Engineering.

Sub-agent fallback: if node execution is denied by the sandbox, read .github/OWNERS directly and apply last-match-wins by hand. All the active rules fit on one screen.

GitHub team → Linear team → GitHub label

The GitHub team label column is what gets applied to the PR after a successful Linear assignment (see reference/label-flow.md).

Linear ticket label rules

When calling the available Linear MCP issue-update tool to assign a ticket to a team, pass a labels array composed of three pieces:

Always-on label

• GitHub — every community PR ticket carries this. In the Linear UI it renders as source > GitHub; the source prefix is a label-group parent, not part of the API name.

Type label (from PR title prefix)

Pass the child label name only — Linear silently drops unknown labels, so don't include type > prefixes.

Team-specific extra label

Worked examples

• feat PR going to Catalysts: ["GitHub", "feature", "Community PR"]
• fix PR going to NODES: ["GitHub", "bug", "community-pr"]
• perf PR going to AI: ["GitHub", "enhancement"]
• chore PR going to Lifecycle & Governance: ["GitHub", "enhancement"]

Destination state

NODES has a dedicated Review lane; every other team handles routing inside their own triage.

This same table governs the issue-ticket state move when a ready PR is linked onto a referenced issue ticket (SKILL.md step 7B): move the issue ticket to Review for NODES, Triage otherwise — keyed off the PR's resolved owner team.
