Borrowing AGENTS.md to curb overengineering? Keep the checks your project actually needs.
A collected X excerpt recommends OpenCode's AGENTS.md to constrain a coding agent's overengineering. Before adopting rules, compare them with the current task, existing conventions and real failure cases, then decide which ones fit.
What to consider
Apply rules to the scope of the current change, then check whether they solve a real problem. A collected X excerpt recommends OpenCode's AGENTS.md, arguing that its guidance can reduce Codex's overengineering and unnecessary defensive code. That is the author's assessment; the excerpt does not provide the full file or comparison results. Start with one rule relevant to a recent task. Use a small change to see whether it reduces extra structure while preserving existing behavior and necessary verification. We have not read the file or reproduced the author's experience.
Set a clear boundary for the current change
Before editing, state the problem, affected files and completion criteria. If the task is to fix a reproduced field-handling error, for example, first list correct and failing inputs. Ask the agent to propose a change around those criteria, making it easier to judge whether additional structure belongs in the task.
If a proposal adds configuration, dependencies or a general-purpose layer, ask which existing requirement it serves and what maintenance it introduces. Keep additions without a clear purpose as separate proposals, then decide whether the current task needs them. This makes the discussion more concrete than a general preference for simplicity.
Check how each rule affects existing project conventions
Compare proposed requirements with existing project instructions, marking duplication, conflicts and conditions of use. A preference for fewer abstractions needs to be understood in the context of the current code. A short rule should not replace interface conventions or delivery requirements that the project has explicitly adopted.
Before removing a check, identify the inputs, known errors or usage scenarios it was intended to handle. Keep corresponding verification for failures that can be reproduced. Investigate code with no documented purpose before deciding what to do. These are review suggestions; the excerpt does not establish how different coding tools load or execute AGENTS.md.
Use actual changes to decide whether a rule should stay
After trying a rule on a clearly scoped task, inspect the files changed, new conditions introduced and whether the original problem was solved. Keep the before-and-after results and records of human intervention. Use them to decide whether the requirement remains useful, rather than adopting it permanently because of one response's style.
If a rule causes essential verification to be skipped or treats an existing requirement as unnecessary design, clarify its conditions and try again. The excerpt provides no general code-reduction or quality-improvement figures, so none are promised here. Keep a rule when you can explain the improvement it produces in this project.
