How to set up Codex with Buffaly
Codex is Buffaly's source-editing partner. Buffaly should decide the goal, inspect evidence, constrain the edit, run validation, and commit only intended files; Codex should handle the focused source or file changes.
Codex, provider backends, and normal tools are different
| Concept | Use it for |
|---|---|
| Codex edit tool | Scoped repository inspection and source/file edits. |
| Model provider backend | The completion transport Buffaly uses for model calls. |
| Typed Buffaly tools | Files, processes, services, sessions, secrets, and domain-native operations. |
Use Codex for editing. Prefer typed Buffaly tools for inspection, validation, provider configuration, secrets, session management, and external-service operations when those tools exist.
When to use Codex
Good fit
- Razor or documentation edits
- Small code fixes
- Multi-file refactors with validation
- Source reorganization where a diff can prove scope
Use another path
- Secrets and credentials
- Runtime service discovery
- Direct SQL or provider configuration
- ProtoScript changes with a typed authoring tool
Safe Codex workflow
- Name the repository and the exact outcome.
- Ask Buffaly to inspect relevant files before editing.
- Limit the edit to the smallest coherent batch.
- Run the project's validation command.
- Review changed files and make sure no unrelated files are included.
- Commit only intended files and report the commit hash.
Good first request: “In the website repo, update one docs page, run the build, and commit only that page if validation passes.”
Walkthrough: Set up Codex inside Buffaly
The built-in walkthrough starts with Step 1 — Choose your first coding target. Pick a small, reversible project or repository first so Buffaly can inspect files, make only scoped edits, validate the result, commit only intended files, and summarize what changed.
Inspect this Buffaly project
Use this when you only want Buffaly and Codex to look at the current project, explain structure, or identify likely edit points.
Help with a small fix
Use this for a narrow, easy-to-verify change such as a docs tweak, route fix, validation error, or small UI correction.
Help with a new feature
Use this only after you can name the target repository, expected behavior, validation path, and acceptance criteria.
If you are unsure, start with inspection only. Move to a small fix after Buffaly has shown evidence from the files, and use a new feature only when the scope is clear enough to split into validated batches.
Validation and commits
A Codex edit is not done when files change. It is done when the intended diff is validated and committed.
- Ask for the validation command and result.
- Ask for a scoped diff summary.
- Ask for the commit hash.
- If validation fails, fix the root cause instead of hiding the failure.
Common failures and recovery
Codex edits the wrong path
Stop and re-anchor the repository root. Ask Buffaly to show the working directory and changed files before continuing.
Codex changes unrelated files
Do not commit the batch. Revert unrelated changes or create a new focused edit batch.
Codex cannot authenticate or reach its backend
Ask Buffaly to inspect local Codex setup and report the missing configuration rather than retrying blindly.
Validation fails after the edit
Use the failure output as evidence and fix the failing contract, syntax, route, or test.
Configuration and credentials, how to ask Buffaly to use Codex, and long-running Codex work
Codex configuration is separate from normal provider/model credentials. Confirm the Codex backend or embedded Codex path is installed, authenticated, and available to the account running Buffaly before asking for source edits.
Ask explicitly: “Use Codex to make this scoped edit, then validate and commit it.” Buffaly should keep ownership of the plan, inspect evidence, bound the edit, and validate the result instead of delegating judgment.
For long-running Codex work, use a durable task, split work into small batches, validate between batches, and keep recovery notes. If Codex fails, rerun only after changing the prompt, scope, or environment condition that caused the failure.
Next
After Codex is working, connect GitHub so Buffaly can combine source edits with repository, issue, and pull request context.
