Our assessment of main-rules
main-rules scores 59/100 on our quality scale, 2730th of 2,863 Automation skills we index.
Its Cursor Rules is 3.2 KB long, well organised into 12 sections with 1 code example: a solid amount of guidance for an agent.
It has no GitHub stars yet, so there is no community track record; judge it on its content.
Maintenance, license and trust
- We could not determine when the repository was last updated.
- Our last check on 2026-10-18 found the source still online.
- No license is declared. By default that means all rights are reserved: you can read it, but reusing or redistributing it is not clearly permitted. Ask the author before building on it commercially.
- Its trust signals score 68/100, with 3 cautions from licensing, adoption, age or documentation. These come from repository metadata, not a code audit — read the skill file before letting an agent act on it.

Overview
This project uses Changesets for automated versioning and release management.
Changeset Workflow
When to Create/Update Changesets
For ANY changes that should result in a version bump and appear in the changelog:
-
Check for existing changesets first:
ls .changeset/*.md | grep -v "README.md" -
If a relevant changeset exists:
- Read the existing changeset file
- Append the new changes to the description
- Do NOT create a new changeset
-
If NO relevant changeset exists:
- Create a new empty changeset:
bun changeset add --empty - Populate it with the package and description
- Create a new empty changeset:
Changeset Format

Brief summary of changes
- Detailed bullet point 1
- Detailed bullet point 2
- etc.
Version Bump Guidelines
- patch (0.1.1 → 0.1.2): Bug fixes, minor tweaks, infrastructure improvements
- minor (0.1.1 → 0.2.0): New features, significant enhancements
- major (0.1.1 → 1.0.0): Breaking changes, major overhauls
Packages in this Project
@tabcanopy/extension- The browser extension package (main package)
When NOT to Create a Changeset
Do NOT create a changeset for:
- Changes that only affect documentation (README updates)
- Changes to tests only
- Typo fixes in comments
- Changes to CI/CD that don't affect the package
Testing
E2E Test Requirements
Most changes should include e2e tests. When making changes to extension behavior:
- Add e2e tests in
packages/e2e-tests/e2e/tab-tree.spec.ts(or relevant file) - Build before testing: E2E tests require a production build
bun run build - Run specific tests to verify your changes:
cd packages/e2e-tests bunx playwright test --grep "your test name" - Run full test suite to check for regressions:
bun run test:e2e
When to Add E2E Tests
Add e2e tests for:
- ✅ New tab creation behavior (window.open, ctrl+click, context menu)
- ✅ Tab tree structure changes (parent-child relationships)
- ✅ Tab movement and repositioning
- ✅ Collapse/expand behavior
- ✅ Tab closing behavior (single, with children, collapsed)
- ✅ Cross-window operations
- ✅ Any user-visible behavior changes
Skip e2e tests only for:
- ❌ Internal refactoring with no behavior changes
- ❌ Type-only changes
- ❌ Documentation updates
- ❌ Pure UI styling changes (consider visual regression tests instead)
Example Workflow
Scenario: User makes changes to extension code and infrastructure
- Check:
ls .changeset/*.mdshowsstrict-colts-watch.mdexists - Read: Check if it's relevant to current changes
- If relevant: Update
strict-colts-watch.mdwith new info - If not relevant: Create new changeset with
bun changeset add --empty
Release Process
The release is automated via GitHub Actions:
- Push changes to
mainwith a changeset - Changesets creates a "Version Packages" PR
- Merge the PR to trigger the release
- Extension uploads to Chrome Web Store as draft
- Manually publish from the dashboard
See docs/RELEASING.md for full details.
