Fix pre_activation GH CLI auth in efficiency improver workflow

[Copilot]

The pre_activation job in the Efficiency Improver workflow fails before activation because a scheduled guard step runs gh pr list without GH CLI auth context. This PR fixes that auth gap so the pre-activation gate can execute as intended.

• Root cause (workflow guard step)

  • In .github/workflows/efficiency-improver.lock.yml, pre_activation step id: check calls:
    • gh pr list --repo "$GITHUB_REPOSITORY" ...
  • That step had no GH_TOKEN env, causing gh to exit with auth error.

• Change made

  • Added step-local token wiring for GH CLI in pre_activation:

    - id: check
      run: |
        MAX_OPEN_PRS=8
        if [[ "$GITHUB_EVENT_NAME" != "schedule" ]]; then exit 0; fi
        COUNT=$(gh pr list --repo "$GITHUB_REPOSITORY" --state open --search 'in:title "[efficiency-improver]"' --json number --jq 'length')
        [[ "$COUNT" -lt "$MAX_OPEN_PRS" ]]
      env:
        GH_TOKEN: ${{ github.token }}

• Scope

  • Single-file, surgical workflow fix.
  • No behavior changes outside the pre_activation auth context.

Greptile Summary

This PR fixes a missing authentication context in the pre_activation job of the Efficiency Improver workflow, where gh pr list was called without a GH_TOKEN env variable, causing the CLI to exit with an auth error on scheduled runs.

• The check step in pre_activation now has env: GH_TOKEN: ${{ github.token }}, which is sufficient given the job's existing pull-requests: read permission scope.
• A trailing newline at the end of the file is also removed as part of the edit.

Confidence Score: 5/5

Safe to merge — the change is a two-line, targeted addition of a well-scoped token to an already-permissioned job step.

The pre_activation job already declares permissions: pull-requests: read, so github.token carries exactly the right scope for gh pr list. The fix is isolated to a single step that previously could not authenticate on schedule events, and no other behavior is changed.

No files require special attention.

Important Files Changed

Filename	Overview
.github/workflows/efficiency-improver.lock.yml	Adds GH_TOKEN env to the check step in pre_activation so gh pr list can authenticate; also removes a trailing newline at EOF.
