Add ctxutil.OrBackground helper to consolidate nil-context fallback duplication

[Copilot]

At least 8 call sites in pkg/cli and pkg/workflow duplicated the same inline nil-context fallback:

if ctx == nil {
    ctx = context.Background()
}

New helper

• Added pkg/ctxutil package with OrBackground(ctx context.Context) context.Context, returning context.Background() when ctx is nil, otherwise ctx unchanged.
• Added table-driven tests covering nil input and a non-nil context.WithValue context.

Migrated call sites

• pkg/cli/retry.go, pkg/cli/signal_aware_poll.go, pkg/cli/setup_repository.go (2 occurrences), pkg/cli/init.go
• pkg/workflow/auto_update_workflow.go, pkg/workflow/compiler_model_pricing.go, pkg/workflow/github_cli_wasm.go

All replaced with:

ctx := ctxutil.OrBackground(opts.Ctx)

Removed now-unused context imports where applicable (e.g. compiler_model_pricing.go). No behavior change — this centralizes the convention and reduces future drift.

Hey @copilot-swe-agent 👋 — thanks for working on the nil-context fallback consolidation!

Process Note: CONTRIBUTING.md explicitly states that this project uses agentic development by a core team only, and 🚫 Traditional Pull Requests Are Not Enabled for non-Core team members. Since you're operating as a core team agent, this appears to follow the intended process—but ensure the authorization is properly established.

On-Topic ✅: This PR addresses a legitimate code quality improvement: consolidating 8+ duplicate nil-context fallback patterns into a single ctxutil.OrBackground helper. The change aligns with the repo's quality standards and maintainability goals.

Current Status: This is a WIP PR with only a planning commit (0 file changes). Before it's ready for review, ensure:

• Add test file — pkg/ctxutil/ctxutil_test.go with table-driven tests covering nil input and non-nil contexts
• Create the helper — pkg/ctxutil/ctxutil.go with the OrBackground(ctx context.Context) context.Context function and doc comment
• Migrate all 8 call sites — Update the files listed in the issue to use the new helper (retryOptions, PollOptions, SetupRepositoryOptions, InitOptions, auto_update_workflow, compiler_model_pricing, github_cli_wasm)

Keep the PR description updated as you make progress. Once all migrations are complete and tests pass (make fmt && make test-unit), this should be ready for review.

Test Quality Sentinel analysis complete. Hard violation found: pkg/ctxutil/ctxutil_test.go missing required (go/redacted):build !integration tag on line 1. Test quality is high (100% design tests with 4 assertions covering nil/non-nil/value preservation), but build tag violation requires fix before merge.

The refactor is clean and correct.

• ctxutil.OrBackground is implemented correctly with proper nil-guard semantics.
• Table-driven tests cover both nil and non-nil cases, including value preservation.
• All 8 call sites migrated consistently; unused context imports removed where applicable.
• No behavior change introduced.

Skills-Based Review 🧠

Applied /codebase-design — this is a textbook deep-module extraction and the change looks great.

📋 Key Themes & Highlights

Positive Highlights

• ✅ OrBackground is the right abstraction: zero-surface-area interface, rich convention enforcement across 8 call sites
• ✅ Package name ctxutil follows the existing -util suffix convention (fileutil, gitutil) — consistent vocabulary
• ✅ Table-driven tests cover both branches (nil → context.Background() singleton check, non-nil → identity + value preservation)
• ✅ compiler_model_pricing.go correctly drops the now-unused context import
• ✅ github_cli_wasm.go correctly uses reassignment (ctx =) rather than short declaration since ctx is already a parameter

No actionable issues found. The change reduces future drift exactly as intended.

TestOrBackground	pkg/ctxutil/ctxutil_test.go:8	design_test, high_value	HARD VIOLATION: Missing required //go:build !integration tag on line 1

⚠️ Flagged Tests (1)

TestOrBackground (pkg/ctxutil/ctxutil_test.go:8) —

• Classification: design_test, high_value (verifies nil-handling contract)
• Violation: Hard failure — missing //go:build !integration tag on line 1
• Coverage: Excellent coverage of nil/non-nil cases with value preservation check (4 assertions, 2 table rows)
• Fix: Add //go:build !integration as the first line of the file

Verdict

❌ FAILED. Hard coding-guideline violation: new Go test file missing required //go:build tag on line 1. According to gh-aw development rules, all *_test.go files must declare either //go:build !integration (unit test) or //go:build integration (integration test) on line 1. This test qualifies as a unit test, so add //go:build !integration at the top of the file.

❌ Test Quality Sentinel: Hard violation detected. New Go test file pkg/ctxutil/ctxutil_test.go is missing required (go/redacted):build !integration tag on line 1. All *_test.go files must declare a build tag per gh-aw conventions. Fix: Add (go/redacted):build !integration as the first line. Test quality is high (1 design test, 4 assertions, comprehensive nil/non-nil/value coverage) but build tag is a blocker.

[github-actions]

Verdict: Approve

Clean, low-risk refactor. Extracts the duplicated nil-context fallback into ctxutil.OrBackground, migrates all 9 call sites, and adds solid table-driven tests covering both nil and non-nil paths.

Review notes

• Verified build (go build ./...) and go vet pass on all touched packages.
• Confirmed the context import remains used in every modified file (still referenced for context.Context type, context.Canceled, context.Background() at other call sites), so no dead imports were introduced.
• Logic is a pure 1:1 behavioral substitution — no functional changes, no edge cases altered.
• Test coverage in ctxutil_test.go is appropriate for the small surface area (nil input, and value-preservation for a non-nil context).

No blocking issues found.

Current head is 9d30ae0.

• ✅ Reviews — no unresolved review threads were returned for this PR, so there was nothing in-scope left for me to address or resolve.
• ✅ Checks (local) — make fmt, make lint, TEST_UNIT_RUN_FULL=1 make test-unit, and make test all passed on the current head.
• ❓ Checks (CI) — the last-known PR checks are green or still in progress, and I found no failed jobs to investigate. CI on the agent head remains unverified until a maintainer re-triggers it.
• ✅ Mergeable — the branch is up to date with origin/main locally (ahead/behind 4 0), and no branch refresh was needed.

Actions taken: refreshed origin/main, verified the branch is current, inspected PR review/check state via MCP, and ran the full required local validation suite.
Hand-off: CI must be re-triggered by a maintainer (close/reopen PR, workflow_dispatch, or push) before merge.
Still needed: maintainer review/merge once CI is re-run for the current head.
