Codex on Work You Can Explain

Adapt Shared Agent Skills to Your Own Workflow

Mon, 24 Aug 2026 00:00:00 -0500

An existing agent skill is a starting point, not an authority. Before you install, combine, or adapt one into a skill you already maintain, inspect what it assumes, compare it with your current workflow, and test the meaningful difference on a small safe task.

Keep at most one bounded adaptation at a time. Preserve the source, version, license, rationale, rejected alternatives, and rollback path. A passing example is evidence about that task and environment. It is not proof that one skill is universally better.

Grow With Skills: Improve the Agent While You Work

A completed task can reveal how a skill should improve, but the task is evidence, not proof. Record the observed gap, separate the reusable lesson from the task’s local context, and propose one bounded change. A shared skill can supply another design to compare, but it is a source, not an upstream workflow you must follow. Keep a local revision only when it addresses an observed need, preserves attribution and boundaries, and passes fresh-task tests.

Package a Repeatable AI Workflow as a Skill

Fri, 24 Jul 2026 00:00:00 -0500

Package a workflow as a skill when it recurs across tasks, contains several steps, requires some agent judgment, and benefits from shared instructions, references, scripts, templates, and a consistent output. Use ordinary code for deterministic operations and AGENTS.md for durable repository rules.

OpenAI’s current Codex Build skills documentation defines an agent skill as a directory with a required SKILL.md. That file supplies a name, a description that helps ChatGPT or Codex decide when to use the skill, and the workflow instructions. The directory can also include scripts, references, and assets. Follow the validation tools in the Codex environment where the skill will run; other products may package or distribute the same workflow differently.

Use `AGENTS.md` to Teach an AI About a Repository

Fri, 24 Jul 2026 00:00:00 -0500

Use AGENTS.md for durable guidance that should apply across many agent tasks in a repository. Put project conventions, reliable setup and verification commands, scope boundaries, and review expectations there. Keep the current objective, temporary context, and one-time preferences in the task prompt.

OpenAI’s current AGENTS.md documentation explains that Codex reads instruction files before working. Instructions closer to the current directory take precedence over broader repository guidance, and an AGENTS.override.md file can replace an AGENTS.md file at the same level. Confirm the files Codex actually loaded before relying on those rules.
