Gh Oss Go Bump

Go Version Bump

Batch workflow for bumping Go versions across multiple OSS repositories. Follows the three-phase pattern: discover and investigate, test locally, then create PRs — with user confirmation gates before every irreversible action.

Step 1: Discover Go Repos and Latest Go Version

Run these two commands in parallel:

1. List Go repos:

   gh oss-watch list
   

   Filter to repos where the language column is "Go".

2. Find latest Go version: Web search for the latest stable Go release. Identify both the latest minor (e.g., 1.26) and latest patch (e.g., 1.26.1).

Present findings to the user:

• Number of Go repos found
• Latest stable Go version
• Key highlights of the new version (security fixes, notable features)

Step 2: Investigate Each Repo (parallelize if possible)

For each Go repo, dispatch one agent to check:

1. Current Go version — fetch go.mod via gh api repos/<owner>/<repo>/contents/go.mod
2. CI version strategy — check if workflows use go-version-file: go.mod or hardcoded versions
3. Open PRs/issues — check for conflicts with gh pr list and gh issue list
4. Test coverage — check for presence of _test.go files
5. Deprecated patterns — scan for io/ioutil, reflect.SliceHeader, or other patterns removed in the target Go version

Each agent returns a structured assessment: repo name, current version, CI strategy, has tests, safe-to-bump verdict, and any concerns.

Present Investigation Summary

Show a table to the user:

| Repo | Current Go | CI Strategy | Has Tests? | Safe? | Notes |
|------|-----------|-------------|-----------|-------|-------|

Flag any repos with:

• Large version jumps (2+ minor versions)
• Old dependencies that may need updating
• Hardcoded Go versions in CI (requires extra file changes)
• No tests (higher risk)

Ask the user to confirm which repos to proceed with before moving to Step 3.

Step 3: Test Locally (parallelize if possible)

After user confirms the repo list, dispatch one agent per repo. Each agent:

1. Clones the repo to /tmp/go-bump/<repo-name>
2. Edits go.mod to set the new Go version
3. Runs go mod tidy
4. Runs go test ./...
5. Reports: success/failure, any test output, any dependency changes from tidy

Important: these are local-only operations — no branches pushed, no PRs created. This phase is purely for verification.

Present Test Results

Show a results table:

| Repo | Old → New | mod tidy | tests | verdict |
|------|-----------|----------|-------|---------|

If any repo fails:

• Show the failure details
• Suggest whether it's fixable (e.g., dependency needs updating) or should be skipped
• Let the user decide

Ask the user to confirm before creating PRs. This is the last gate before irreversible actions.

Step 4: Create PRs (parallelize if possible)

Only after explicit user confirmation. Dispatch one agent per repo using the already-cloned repos in /tmp/go-bump/. Each agent:

1. Creates branch chore/bump-go-<version> (e.g., chore/bump-go-1.26.1)
2. Stages go.mod and go.sum
3. Commits: chore: bump Go version from <old> to <new>
4. Pushes with -u flag
5. Creates PR via gh pr create:
   • Title: chore: bump Go version to <new>
   • Body includes: version change, key improvements (security fixes, performance), and local test results

Each agent returns the PR URL.

Present PR Summary

Show all created PRs in a table:

| Repo | PR URL |
|------|--------|

Step 5: Merge (only if user explicitly requests)

Never auto-merge. Only proceed when the user explicitly asks to merge.

Check CI First

gh pr checks <number> --repo <owner>/<repo>

Present CI status for all PRs. If any are still running, wait and re-check.

Merge

After all checks pass and user confirms:

gh pr merge <number> --repo <owner>/<repo> --squash --delete-branch

If --squash fails (repo settings), try --merge. If that also fails, try --rebase.

Present final status table showing all merged PRs.

Step 6: Cleanup

After all PRs are merged (or the workflow is done):

rm -rf /tmp/go-bump/

Confirmation Gates

This workflow has three user confirmation points before irreversible actions:

Never skip these gates. If the user says "do everything", still present the investigation summary (Gate 1) — but you may proceed through Gates 2 and 3 without pausing if the user explicitly asked for full automation.

Key Principles

• Maximize parallelism — investigate, test, and create PRs concurrently across repos
• Test before pushing — always verify locally with go mod tidy and go test ./...
• Confirm before irreversible actions — PRs and merges require explicit user approval
• Skip gracefully — if a repo fails testing, skip it and continue with the rest
• Clean up — remove /tmp/go-bump/ clones when done
• Detect merge strategy — repos may require squash, merge, or rebase; try squash first
