Give Codex the business context behind the code.

Use the plan to define what Codex should implement

Repository instructions can explain where code belongs and which checks to run. They may say very little about who is allowed to change a record or what must happen after an approval. Those are product requirements, and they need to accompany the coding task.

AlphaTales develops the project context into reviewed workflows, feature specifications, and architecture direction. Give Codex the relevant feature and its surrounding workflow so it can connect an individual change to the expected business behaviour. Keep the task small enough that your team can review the result.

Use local files or request context through Build MCP

With Dev Pack, you select the planning material to export and let Codex read the extracted files in its workspace. This is a useful route when you want to review exactly which version of the plan accompanies the code. The download does not update itself when someone edits the plan.

For a connected workflow, Codex supports MCP servers. AlphaTales Build MCP provides project selection, planning context, and feature details that include requirements and acceptance checks. Authenticate, confirm the project, and ask for the relevant feature context before implementation. Connection support depends on the Codex surface and environment you use.

Configure AlphaTales for Codex

Keep repository instructions and project requirements distinct

Codex reads AGENTS.md instructions to understand how to work in a repository. Use those instructions for conventions, commands, and review expectations. AlphaTales supplies the project-specific behaviour and planning decisions. The two serve different purposes and should agree.

Ask Codex to inspect the implementation before proposing a change. If a requirement conflicts with the current architecture, have it explain the conflict and the options. Resolve the decision rather than letting the agent silently reinterpret the requirement.

Use the plugin for the wider planning journey

The AlphaTales Agent package combines planning and build connections with workflow skills. Its build skill verifies planning completion, selects the project in Build MCP, and guides the handoff. A Codex environment that supports the package can use that workflow; the package is separate from a Dev Pack download or a direct MCP server connection.

Installing a package does not grant access to every project or complete account authentication. Confirm the available tools and selected project before asking Codex to work. The coding and local repository changes still happen in the coding client's environment.

Review the implementation against the plan

This combination is useful when a business team defines the behaviour and a developer uses Codex to implement it, or when the project has rules that cannot be inferred from the code. The plan gives both people a common reference.

Have Codex report the checks it ran and any requirement it could not verify. Review permissions, exception paths, and the diff before release. If the plan changes, refresh the context before continuing. AlphaTales helps prepare the work; it does not make generated code correct by default.
