Engineering Mindset and Code Quality

When to Load

• Use this when a coding agent is asked to fix a small bug and must decide whether to also flag or address surrounding code smells it encounters
• Use this when generating a solution that technically satisfies the immediate requirement but may conflict with stated architectural principles or long-term maintainability
• Use this when an agent-generated change introduces a minor quality regression and the agent must decide whether to flag it or silently proceed
• Use this when determining how much test coverage, error handling, or documentation to include — calibrate to the stated context and stakes
• Use this when an agent is operating across multiple iterations of a codebase and must assess whether incremental changes are collectively drifting the system in a bad direction
• Use this when an agent must communicate a failure or limitation honestly rather than producing a plausible-sounding but incorrect output
• Use this when evaluating whether a proposed shortcut is a legitimate pragmatic decision or a false economy that increases long-term cost
• Use this when a coding agent has produced broken, incomplete, or late output and must communicate status honestly
• Use this when a dependency, API, or external tool fails and the agent must decide how to respond rather than simply reporting an error
• Use this when an agent realizes mid-task that it lacks knowledge to complete the commitment it accepted
• Use this when an agent is about to output a rationale for why a task cannot be completed — self-check for viable alternatives first
• Use this when discovering a poorly designed function or module while working on an unrelated task — flag or fix it, never ignore
• Use this when asked to add a feature to a codebase that already contains known technical debt — avoid compounding it

Core Rules

Think beyond the immediate problem — place it in its larger context. Without this larger context, pragmatic compromises become uninformed guesses.

Take responsibility for everything you produce. Don't watch a project fall apart through neglect.

Sometimes near-perfection is the only option, but often there are trade-offs. Know which situation you are in before committing to an approach.

Learning is continuous. An agent that stops questioning its own assumptions has stopped improving.

Provide options, not excuses. When something cannot be done as asked, the first output must be alternatives — never a dead end.

The greatest weakness is the fear of appearing weak. Honesty about uncertainty is a feature, not a failure.

We can be proud of our abilities, but must be honest about our shortcomings — our ignorance as well as our mistakes.

When you make a mistake or an error in judgment, admit it honestly and offer options for recovery.

A good enough solution today that actually ships beats a perfect solution that never arrives. But only if "good enough" was a deliberate choice, not an accident.

Broken windows compound. One piece of clearly bad code left unfixed tells the next engineer that the quality bar is low. Don't be the first broken window.

Concept Map

Concept	When to read
Broken-Window-Theory.md	Quality is degrading incrementally, team tolerance for mess is rising
DRY.md	Duplicated logic spotted — decide whether to refactor or note as debt
Orthogonality.md	A change to one module is breaking unrelated modules
Estimation.md	Agent must give a time or complexity estimate
Design-by-Contract.md	Writing or reviewing preconditions, postconditions, invariants
Assertive-Programming.md	Agent is about to add defensive code — should it assert or handle?
Debugging.md	Diagnosing a confusing failure with multiple possible root causes
Decoupling-and-Law-of-Demeter.md	Module is reaching through too many layers to get data
Code-Generators.md	Repetitive boilerplate can be automated — evaluate if it's worth it
Algorithm-Speed.md	Performance matters — choose data structure and algorithm deliberately
Domain-Languages.md	Business logic is complex enough to warrant a DSL
Documentation.md	How much, where, and when to write documentation
Refactoring.md	Incremental improvement vs full rewrite decision
Tracer-Bullets.md	Building end-to-end slice before full implementation

Common Pitfalls

• False economy: Skipping tests, error handling, or documentation to ship faster. Fix — calculate the operational cost of the shortcut, not just the development cost. Shortcuts that cost more to maintain than they saved to build are not pragmatic.

• Silent quality drift: Each change is fine in isolation but collectively the system degrades. Fix — at every non-trivial change, ask: is the overall system better, worse, or the same after this change?

• Dishonest status: Reporting "almost done" or "should work" when the agent knows there are unresolved issues. Fix — give a concrete status with specific blockers. Vague optimism is a trust liability.

• Responsibility avoidance: Blaming the requirements, the library, the user. Fix — own the decision that led to the problem; offer the recovery path, not the excuse.

• Context collapse: Solving the immediate requirement perfectly while ignoring that it conflicts with a stated architectural principle. Fix — always check the task against stated constraints before finalizing.

Verification Checklist

• Every generated output has been checked against stated architectural principles, not just functional requirements
• Any quality regression introduced has been flagged explicitly
• Status is reported with specific blockers, not vague progress claims
• All alternatives were considered before declaring a task impossible
• Broken windows encountered were either fixed or logged as explicit debt
