Linear Issue Tracking

We track tickets and projects in Linear (https://linear.app). Use the linearis CLI tool via Bash.

Run linearis usage to see all available commands and options.

Quick Reference

Command	Purpose
linearis issues read ABC-123	Get issue details + attachments
linearis issues search "keyword"	Search issues
linearis issues create "Title" --team Team	Create issue
linearis issues update ABC-123 --status "Done"	Update issue
linearis comments create ABC-123 --body "text"	Add comment
linearis documents list --issue ABC-123	List attached docs
linearis embeds download "<url>" --output ./file --overwrite	Download attachment

Conventions

• Ticket format: ABC-<number> (e.g., FOR-123)
• Always reference tickets by their identifier
• When creating subtasks, use parent ticket's project by default
• If project unclear when creating tickets, ask the user

Workflow: Starting Work on an Issue

When the user asks to start working on a Linear issue, these steps must be included in your plan (using TodoWrite or similar planning tools):

1. Read the issue details:

   linearis issues read ABC-123
   

2. Switch to main branch:

   • Ensures you're creating the feature branch from the latest main
   • Avoids creating branches from other feature branches

   git checkout main
   git pull origin main
   

3. Create a feature branch:

   • Branch name format: feature/ABC-123-brief-description
   • Example: feature/FOR-123-add-costs-projection

   git checkout -b feature/ABC-123-brief-description
   

4. Update issue status to "In Progress":

   linearis issues update ABC-123 --status "In Progress"
   

5. Implement the feature:

   • Follow the task requirements from the issue description
   • Add progress comments as needed

6. Verify implementation and get user sign-off:

   • Before committing, verify the implementation matches the plan
   • Suggest running: /verify-plan <PLAN-PATH> (if a plan file exists)
   • Wait for explicit user approval before proceeding to create the PR
   • This ensures the work meets requirements and follows the intended approach

7. When complete and approved, create a pull request:

   git push -u origin feature/ABC-123-brief-description
   gh pr create --title "ABC-123: Brief description" --body "Resolves ABC-123\n\n## Summary\n- Implemented feature...\n\n## Test plan\n- [ ] Tested scenario..."
   

8. Update issue status to "In Review":

   linearis issues update ABC-123 --status "In Review"
   

Critical: When planning work on a Linear issue, include ALL these workflow steps in your TodoWrite plan. Don't just implement the feature - the plan must include branch creation at the start, user sign-off verification before committing, and PR creation at the end.

Workflow: Investigating an Issue

When the user asks to investigate/explore/look into a Linear issue (without immediately implementing):

1. Read the issue details with linearis issues read ABC-123
2. Search the codebase for related files (grep for keywords, component names, API endpoints mentioned in the ticket)
3. Summarize findings directly to the user with:
   • Ticket requirements and acceptance criteria
   • Relevant files and their roles
   • Proposed implementation approach
   • Open questions or blockers
   • Estimated complexity (S/M/L)

Always produce a visible summary even if the investigation is cut short. The summary is the deliverable.

Working with Issues

Read issue with attachments:

linearis issues read ABC-123

Returns JSON including an embeds array containing uploaded files (screenshots, documents, etc.) with signed download URLs and expiration timestamps.

Download attachments to .linear-tmp/ (gitignored):

mkdir -p .linear-tmp
linearis embeds download "https://uploads.linear.app/..." --output .linear-tmp/screenshot.png --overwrite

Progress Updates

• When task status changes in ticket description (e.g., - [ ] task → - [x] task), update the description accordingly
• When adding progress reports (more than checkbox changes), add as ticket comment:

linearis comments create ABC-123 --body "Progress update: ..."

Authentication

A project-local token file .linear_api_token exists in the project root. Always pass it explicitly when running linearis commands:

linearis --api-token "$(cat .linear_api_token)" <command>

Do NOT rely on ~/.linear_api_token or LINEAR_API_TOKEN env var — those may belong to a different team.
