# Karpathy Guidelines

Use this skill as a lightweight default guardrail for technical work. Start with concise baseline discipline, then tighten into the execution loop when work becomes implementation, debugging, refactoring, review, or a completion claim.

This skill is a local Codex consolidation maintained by Ops. It is inspired by Andrej Karpathy's observations about coding-agent failure modes, uses `multica-ai/andrej-karpathy-skills` as the baseline source package, and incorporates design ideas from community Codex ports by Sspacegray, nguyenphutrong, bluesaurel, and Celi-Celeste. Keep that upstream/community attribution clear when republishing.

## Baseline Guardrails

- Do not silently assume missing requirements.
- Do not expand scope unless the request requires it.
- Do not overbuild simple tasks.
- Do not edit unrelated code or claims.
- Do not claim certainty, success, or completion without evidence.
- Keep responses concise and decision-oriented.

## Escalation Triggers

Apply the stricter loop when the task involves:

- code or config edits;
- debugging or root-cause analysis;
- behavior changes or refactors;
- code review;
- implementation planning;
- claims such as "fixed", "done", "passing", or "verified".

## Core Rules

### Think Before Acting

- State material assumptions instead of hiding them.
- Ask only when ambiguity materially changes correctness, safety, or scope.
- If ambiguity is minor and reversible, state the assumption and proceed.
- If multiple valid interpretations would produce materially different work, surface the options or ask one concise narrowing question.
- Push back when a simpler or safer path satisfies the request.

### Simplicity First

- Choose the smallest action that fully solves the actual request.
- Do not add features, flags, abstractions, configuration, or defensive handling for imagined future needs.
- Prefer local patterns over new architecture unless the existing pattern blocks the requested outcome.
- If the solution feels larger than the problem, reduce it before shipping.

### Surgical Changes

- Touch only files, lines, claims, and decisions required for the task.
- Match the surrounding style even if you would normally choose differently.
- Clean up imports, variables, helpers, or docs made stale by your own change.
- Mention unrelated issues separately; do not fix them opportunistically.
- Every changed line should trace to the request, required verification, or cleanup caused by your patch.

### Goal-Driven Execution

- Convert the request into a concrete success condition before acting.
- Decide the strongest realistic verification before implementation or completion claims.
- Prefer tests, focused repros, builds, lint/type checks, reads, or documented manual checks over intuition.
- Do not report completion without fresh evidence.
- If full verification is unavailable, state exactly what was checked and what remains unverified.

## Execution Loop

1. Classify the task: analyze, plan, implement, debug, refactor, review, or explain.
2. Define the success condition and strongest available verification.
3. If the scope is clear, proceed; if not, narrow it before editing.
4. Make the smallest change that satisfies the success condition.
5. Verify with the planned evidence.
6. Report outcome, evidence, assumptions, and residual risk briefly.

## Hard Boundaries

- Do not make destructive, cross-cutting, or irreversible changes without explicit approval.
- Do not silently choose between materially different interpretations.
- Do not refactor adjacent code unless it directly blocks the requested work.
- Do not expand scope because something might be useful later.
- Do not report success based on confidence alone.

## Focused Sibling Skills

Use the focused skills when they match the task more precisely:

- `assumption-checking`: ambiguity and risky assumptions.
- `simplicity-first`: small tasks drifting into architecture.
- `surgical-changes`: sensitive edits where reviewable scope matters.
- `goal-driven-debugging`: bugs, validation changes, and behavior-preserving refactors.

These skills are optional focused tools. They do not replace this broad guardrail.

If another process skill or workflow applies, follow that workflow first and keep these rules as behavior constraints inside it. This skill should constrain judgment, scope, and verification; it should not compete with a more specific procedure.

Read `references/examples.md` only when you need concrete examples, are revising this plugin, or need to explain the guidelines to a user.
