3-15: 同じ backend 変更でフルテストが二重実行されています。
.github/workflows/ci.yml:1-46でも同じ push 条件でcargo test --all --all-featuresを実行していて、cargo llvm-covも内部でテストを走らせます。backend 変更のたびに同等のテストが 2 回走るので、PR 待ち時間と Actions コストがかなり増えます。coverage を毎回必須にしないなら、main/developへの push のみに絞るかworkflow_dispatchに逃がす方が軽いです。🤖 Prompt for AI Agents

In @.github/workflows/backend-coverage.yml:
- Around line 3-15: The backend coverage workflow is causing duplicate full test
runs because .github/workflows/backend-coverage.yml triggers on: push with
branches: - main - develop - feature/** (and on pull_request) while
.github/workflows/ci.yml already runs cargo test (and cargo llvm-cov runs tests
too); fix by narrowing the backend-coverage.yml triggers — e.g., remove
feature/** from on.push.branches and only keep main and develop, or replace the
push trigger with workflow_dispatch (manual) and adjust pull_request accordingly
— update the on: push / branches and/or add workflow_dispatch entries in
backend-coverage.yml so full tests aren’t run twice (reference: on: push,
branches: - main - develop - feature/**, pull_request, cargo llvm-cov,
.github/workflows/ci.yml).
- Line 30: Replace the external GitHub Action version tags with pinned commit
SHAs for each referenced action to prevent supply-chain changes: update usages
of actions/checkout@v4, dtolnay/rust-toolchain@stable, actions/cache@v4,
taiki-e/install-action@cargo-llvm-cov, and codecov/codecov-action@v5 to the
corresponding full commit SHA values in the workflow file; ensure you fetch the
canonical commit SHAs from each action's upstream repository and replace the tag
references with the SHA strings (keeping the same owner/repo names) so the
workflow runs a fixed commit.
