# Fix failing dependency-bot CI (https://www.shipfox.io/docs/examples/fix-dependency-ci) Description: Get a tested fix for every dependency update that breaks CI. Starts when: CI fails on a dependency-bot pull request. Integrations: GitHub. ## How it works 1. **A dependency update fails CI.** Dependabot or Renovate opens a pull request, and a check fails. 2. **The agent finds the cause.** It reads the failed logs and the changes in the update. 3. **The workflow runs your checks again.** The checks confirm that the fix works. 4. **The workflow pushes the fix or proposes it.** It pushes to the branch of the bot, or it posts a patch as a comment. ## What it writes - GitHub: Pushes to the bot branch or comments with a patch. ## Before you start - Connect GitHub. - Run CI on GitHub Actions, with Dependabot or Renovate opening update pull requests. - To push fixes, let the Shipfox app commit to the branches of the bot. ## Choices you make When you set up this workflow, your coding agent asks you these questions. The workflow file on this page uses the default answers. ### Which dependency bot opens update pull requests? - **Dependabot** (default): Repairs pull requests authored by Dependabot after its initial CI run fails. - **Renovate**: Repairs pull requests authored by Renovate after its initial CI run fails. - **Custom bot login**: Requires the exact GitHub login used by the bot. ### What should the workflow do after the fix passes? - **Push the fix** (default): Updates the bot branch and posts the result. Existing auto-merge rules can merge the repair. - **Comment only**: Leaves the branch unchanged and posts a tested patch or an actionable diagnosis. ## Models When you set up this workflow, your coding agent suggests models that your workspace can use. You choose the model for each step. - `fix`: Reads failed CI logs and repairs the dependency update branch. Tested with `gpt-6-sol` at high thinking. ## Set up this workflow Open your coding agent in your repository and paste this prompt. The agent needs the [Shipfox MCP server](https://www.shipfox.io/docs/how-to/set-up-work/connect-mcp-client). ```text Use Shipfox to create a workflow from the fix-dependency-ci template. ``` The workflow file, `.shipfox/workflows/fix-dependency-ci.yml`, with every default: ```yaml # yaml-language-server: $schema=https://www.shipfox.io/docs/workflow.schema.json # shipfox-template: fix-dependency-ci@2 source=github name: Fix failing dependency-bot CI runner: shipfox concurrency: group: 'dependency-ci-${{ event.repository.full_name }}-${{ event.workflow_run.pull_requests[0].number }}' cancel_in_progress: false triggers: on_dependency_ci_failure: source: github_source event: workflow_run.completed # Replace replace-with-owner/repository with the selected project repository before enabling this workflow. # option:bot_identity filter: >- event.repository.full_name == "replace-with-owner/repository" && event.workflow_run.conclusion == "failure" && event.workflow_run.pull_requests.size() == 1 && event.workflow_run.run_attempt == 1 && event.workflow_run.actor.login == "dependabot[bot]" jobs: inspect: checkout: false outputs: eligible: ${{ steps.read_pr.outputs.open && steps.read_pr.outputs.author == event.workflow_run.actor.login && steps.read_pr.outputs.repository == event.repository.full_name && steps.read_pr.outputs.branch == event.workflow_run.head_branch && steps.read_pr.outputs.head_sha == event.workflow_run.head_sha }} head_sha: ${{ steps.read_pr.outputs.head_sha }} steps: - key: read_pr tool: pull_request_read.get connection: github_source with: owner: ${{ event.repository.owner.login }} repo: ${{ event.repository.name }} pull_number: ${{ event.workflow_run.pull_requests[0].number }} outputs: open: ${{ result.state == "open" }} author: ${{ result.user.login }} repository: '${{ result.head.repo != null ? result.head.repo.full_name : "" }}' branch: ${{ result.head.ref }} head_sha: ${{ result.head.sha }} fix: needs: inspect if: ${{ needs.all(n, n.status == "succeeded") && jobs.inspect.outputs.eligible }} checkout: false outputs: outcome: ${{ steps.deliver.outputs.outcome }} commit: ${{ steps.deliver.outputs.commit }} patch_base64: ${{ steps.deliver.outputs.patch_base64 }} summary: ${{ steps.fix_failure.outputs.summary }} steps: - key: checkout_dependency_branch checkout: connection: github_source repository: ${{ event.repository.full_name }} ref: ${{ jobs.inspect.outputs.head_sha }} fetch-depth: 0 permissions: contents: write # slot:setup_commands - key: confirm_clean run: | if [ "$(git rev-parse HEAD)" != "$EXPECTED_HEAD" ] || [ -n "$(git status --porcelain)" ]; then echo "Bootstrap changed the checkout.

Read the PR diff with pull_request_read get_diff to understand the intended upgrade. Reproduce the failed check, including installation errors, before choosing a repair. Preserve the intended dependency upgrade. Do not revert or downgrade it, weaken tests, disable checks, remove security controls, or edit GitHub workflow files. Missing credentials, service outages, unconfirmed flakes, and checks that cannot run here need a diagnosis, not speculative edits. Choose one status: - repair_candidate: make the smallest repair that preserves the upgrade. Inspect the complete diff, including installation changes. Stage only the intended files with explicit git add paths, including new files. Set commit_title to a concise message following repository conventions. - no_change_needed: no repair is needed and the configured local checks pass. Leave no changes. Do not claim that GitHub CI passed. - needs_human: explain the missing configuration, unsupported check, migration decision, or other blocker. No changes will be delivered. Remove unrelated setup or test output from the proposed changes. Do not commit, push, comment, enable auto-merge, or rerun GitHub Actions. Later steps validate and deliver the result. Keep summary under 2000 characters: explain the cause, intended upgrade, changed files, checks you actually ran, and any remaining uncertainty. It must not claim a push or CI success.
