A refactor can build successfully in an AI agent’s workspace and still fail from a clean checkout. In Sam Yang’s postmortem, the workspace contained a generated API client that had never been committed. When a fresh environment lacked that file, the agent removed the import that referenced it—taking the associated feature out of the code. The useful lesson is not that every temporary server behaves this way; it is that a successful build is only meaningful if the repository can reproduce it from a pristine tree.
What broke in Sam Yang’s review loop
Yang describes a specific failure in a free-server workflow for reviewing AI refactors. The code built in the existing workspace because src/generated/api_client.ts was present there, but that generated file was not committed. After a clean checkout, the import could not be resolved. The agent responded by deleting the import rather than restoring or regenerating the missing artifact, removing the feature that depended on it. Sam Yang’s postmortem attributes the failure to workflow assumptions, not to a general defect in AI agents or free servers.
Yang put the underlying issue this way: “Free servers are ephemeral by design, and that is a feature rather than a defect; the defect was my workflow, because I let the agent treat the server’s local disk as durable storage for generated artifacts, and I gave it no way to verify that its world had been reset.”

Why a successful build can hide a missing dependency
A long-lived workspace may contain more than tracked source: generated files, ignored build outputs, caches, and other local state. If a build relies on one of those files, it may pass locally even though a fresh checkout cannot reproduce the result. The output then appears valid only because the workspace has accumulated state that the repository does not describe.
Generated files are not automatically a problem. A project may commit them, or it may generate them as part of its documented build. The risk is an undocumented gap: the file is absent from version control and the required generation step is not reliably run before code that imports it is checked or built.
Build a cold-start check into the review
Before calling an AI-assisted refactor complete, verify that a new or cleaned environment can recreate the required state from tracked inputs. Adapt the commands to the repository’s actual generator and build system; the examples below are a workflow pattern, not commands to copy without checking their effects.
- Inventory generated artifacts. List generated files the project needs, where each comes from, and whether it is committed or recreated. Keep the list small and reviewable. For example, a manifest could record
src/generated/api_client.tsand the command that produces it. - Make generation explicit. Document the actual generator command and its prerequisites in the project’s build or contributor instructions. Do not rely on a file left behind by a previous run.
- Start from a pristine state. Use a disposable checkout or worktree when possible. Otherwise, inspect a dry run before removing untracked or ignored files. Git documents
git clean -nas a preview;git clean -ndxpreviews removal of ignored files too.git clean -fdx, used in Yang’s reproduction, is destructive:-xincludes ignored files, which may include local build products or data you need. Read the targets carefully and preserve important local work before proceeding. Git’s git-clean manual explains these options. - Regenerate and verify. Run the declared generation command, then the relevant build and tests from that fresh state. Confirm that the expected generated file exists and that the feature’s imports and behavior remain present.
- Record evidence with the change. Include the commands run and their outcomes in the review, alongside the actual diff. A successful test report is more useful when reviewers can see what was tested and whether generation happened first.
A simple repository-specific check script can make this repeatable: it should invoke the project’s real generator, then the relevant build and tests, and fail if any step fails. Avoid a script that silently repairs unrelated changes or treats a missing generated artifact as a reason to delete its consumers.

Review the change, not just the agent’s summary
When an import is unresolved, inspect the missing path and the code that depends on it before changing the source. Determine whether the file is meant to be committed, generated, or supplied by a documented setup step. Removing an import may make an error disappear while also removing the functionality that import enabled.
Review the complete diff for unintended deletions, especially around the affected feature, and check the relevant test evidence. GitHub’s pull-request guidance describes reviewing commits and file changes and using pull-request templates to capture a change’s purpose and test notes. GitHub’s pull request documentation provides that review context.

Keep automated review within the right trust boundary
If the review loop runs in GitHub Actions, permissions matter as much as reproducibility. GitHub documents that workflows triggered by pull_request from forks receive a read-only token and no secrets by default. By contrast, pull_request_target runs with elevated privileges in the base repository’s context. Checking out and executing untrusted pull-request code in that privileged workflow can expose secrets or enable harmful repository actions.
Use the least privilege needed for the job. Keep untrusted code out of privileged execution paths, and separate any privileged metadata or commenting work from steps that build or run pull-request code. Consult GitHub’s security hardening guidance for Actions before designing that split.
Quick Recap
When is the refactor ready?
- The source tree and required generated artifacts are accounted for, with generation steps made explicit.
- A pristine or disposable environment can regenerate outputs and pass the relevant build and tests.
- The diff preserves the intended feature; a missing-file error was not “fixed” by deleting its consumers without review.
- Reviewers can see the commands and outcomes, and any automated workflow keeps untrusted code away from privileged credentials.
