Principles

  • Keep it simple (KISS) — prefer the simplest solution that works
  • Don't repeat yourself (DRY) — extract when you see three duplicates, not before
  • Single Responsibility — each module/function does one thing
  • Use descriptive, intention-revealing names
  • Use kebab-case for files and folders
  • Functions should have clear inputs and outputs with minimal side effects
  • Keep functions right-sized — extract when logic needs a comment to explain
  • Delete dead code — don't comment it out
  • Never swallow errors silently
  • Measure before optimizing — no premature performance work
  • No premature abstraction — wait for three concrete duplicates before extracting

Rules

See rules index for detailed patterns.

Examples

Positive Trigger

User: "Review this service and remove duplication while keeping behavior unchanged."

Expected behavior: Use core-coding-standards guidance, follow its workflow, and return actionable output.

Non-Trigger

User: "Generate a one-off product marketing tagline."

Expected behavior: Do not prioritize core-coding-standards; choose a more relevant skill or proceed without it.

Troubleshooting

Skill Does Not Trigger

  • Error: The skill is not selected when expected.
  • Cause: Request wording does not clearly match the description trigger conditions.
  • Solution: Rephrase with explicit domain/task keywords from the description and retry.

Guidance Conflicts With Another Skill

  • Error: Instructions from multiple skills conflict in one task.
  • Cause: Overlapping scope across loaded skills.
  • Solution: State which skill is authoritative for the current step and apply that workflow first.

Output Is Too Generic

  • Error: Result lacks concrete, actionable detail.
  • Cause: Task input omitted context, constraints, or target format.
  • Solution: Add specific constraints (environment, scope, format, success criteria) and rerun.

Workflow

  1. Identify whether the request clearly matches core-coding-standards scope and triggers.
  2. Apply the skill rules and referenced guidance to produce a concrete result.
  3. Validate output quality against constraints; if gaps remain, refine once with explicit assumptions.
