Skill: pdq-add-ticket-to-pr

Overview

Use this workflow when asked to attach an issue/ticket to PDQ work. It creates a Platform Linear issue, handles either an existing PR or an unpushed branch, updates the PR title, waits for the Linear linkback comment, and reruns the Ensure work is ticketed check when a PR exists.

Scope Guardrail (required)

Run this skill only in PDQ repositories.

  • Verify remote first: git remote get-url origin
  • Continue only if remote matches github.com/pdq/ (SSH or HTTPS)
  • If not a PDQ repo, stop and report that this skill is out of scope

Inputs

  • PR number (optional; infer from current branch if a PR exists)
  • Short ticket title
  • Ticket body/context (PR URL, commit SHA, flaky/failure context)

Linear IDs

  • Platform team ID: c1bc5af0-4726-4381-b85b-49e0fabd3b31
  • Dorian user ID: e243e478-d3b3-4be0-84cc-cbb301e47ab6
  • 📋 Engineering Task label ID: 9e12be59-5086-4064-afb3-b4dbf005effa

Tool preference

  • Prefer GitHub MCP for GitHub operations when available
  • Use gh CLI as the fallback for GitHub operations
  • Use Bash for local git commands such as remote checks, upstream checks, commit SHA lookup, and branch rename
  • Use Linear MCP for Linear issue creation and gitBranchName lookup

Efficient Workflow

  1. Determine whether a PR already exists for the current branch.

    • gh pr view --json number,title,url,headRefName,baseRefName if no PR was provided
    • If this fails and git rev-parse --abbrev-ref --symbolic-full-name @{u} also fails, treat this as the no-PR/no-upstream path
    • git log -1 --format="%H" for commit SHA

  2. Create the Linear issue in Platform with the correct label.

    • Team: Platform (always use this)
    • Linear Issue Label: 📋 Engineering Task (always required)
    • Capture the returned issue ID (for example PLT-2976)

    If this is the no-PR/no-upstream path, fetch the created issue with the Linear MCP and rename the local branch before first push:

    • Use the issue's gitBranchName field exactly; this is Linear's Copy git branch value, for example plt-3282-finish-oban-migration
    • git branch -m <linear-git-branch-name>
    • Do not rename if a PR exists or the branch is already pushed

  3. If a PR exists, update the PR title by appending the issue id suffix.

    • Target format: <existing title> [PLT-xxxx]
    • the PR title must remain in conventional commits format and the issue id should always be appended at the end of the title. If the title becomes longer than 72 characters after adding the ticket you should rewrite it to be shorter without losing the intent/meaning and keeping conventional commits
    • Do not duplicate key if already present

  4. If a PR exists, wait for Linear linkback comment on the PR.

    • Poll gh api repos/pdq/<repo>/issues/<pr>/comments
    • Success condition: comment from linear[bot] or comment body containing the exact ticket key

  5. If a PR exists, rerun ticketing check in the fastest way.

    • Find failing check link from gh pr checks <pr> --json name,state,link
    • Locate Ensure work is ticketed
    • Extract run id from link: .../actions/runs/<run_id>/job/...
    • Rerun only failed jobs in that run: gh run rerun <run_id> --failed
    • Poll gh pr checks until Ensure work is ticketed is SUCCESS or FAILURE

Command Patterns

Prefer GitHub MCP equivalents when available; use these gh commands as fallbacks.

  • PR metadata:
    • gh pr view <pr> --json number,title,url,headRefName,baseRefName
  • Check status:
    • gh pr checks <pr> --json name,state,link
  • Rerun ticket check:
    • gh run rerun <run_id> --failed
  • Wait for check:
    • poll gh pr checks for Ensure work is ticketed
  • Wait for Linear comment:
    • poll gh api repos/pdq/<repo>/issues/<pr>/comments

Completion Criteria

  • Linear issue exists in Platform with 📋 Engineering Task label
  • If no PR/upstream existed, local branch is renamed to the issue's gitBranchName
  • If a PR exists, PR title ends with [PLT-xxxx]
  • If a PR exists, Linear bot linkback comment exists on the PR
  • If a PR exists, Ensure work is ticketed is rerun and finishes SUCCESS

Notes

  • Keep changes low-risk: this workflow only updates metadata (ticket + PR title + CI rerun)
  • If Linear comment does not appear after reasonable retries, report partial completion and include current check state
