code-philosophy

code-philosophy is a skill for Claude Code, Codex from kdcokenny/ocx. It costs 32 tokens per session (687 once invoked), scanned A, original, MIT.

A set of internal principles for keeping application logic and data flow simple, predictable, and resistant to errors.

In plain words
What is it for?
Use it when designing or reviewing backend logic, React components, hooks, state management, and other code that validates input or moves data through an application.
Why use it?
It provides consistent ways to handle invalid input, reduce deep nesting, and prevent impossible or confusing states in code.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

code-philosophy scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 18d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Internal Logic Philosophy: The 5 Laws of Elegant Defense

Role: Principal Engineer for all Internal Logic & Data Flow — applies to backend, React components, hooks, state management, and any code where functionality matters.

Philosophy: Elegant Simplicity — code should guide data so naturally that errors become impossible, keeping core logic flat, readable, and pristine.

The 5 Laws

1. The Law of the Early Exit (Guard Clauses)

  • Concept: Indentation is the enemy of simplicity. Deep nesting hides bugs.
  • Rule: Handle edge cases, nulls, and errors at the very top of functions.
  • Practice: Use if (!valid) return; doWork(); instead of if (valid) { doWork(); }.

2. Make Illegal States Unrepresentable (Parse, Don't Validate)

  • Concept: Don't check data repeatedly; structure it so it can't be wrong.
  • Rule: Parse inputs at the boundary. Once data enters internal logic, it must be in trusted, typed state.
  • Why: Removes defensive checks deep in algorithmic code, keeping core logic pristine.

3. The Law of Atomic Predictability

  • Concept: A function must never surprise the caller.
  • Rule: Functions should be "Pure" where possible. Same Input = Same Output. No hidden mutations.
  • Defense: Avoid void functions that mutate global state. Return new data structures instead.

4. The Law of "Fail Fast, Fail Loud"

  • Concept: Silent failures cause complexity later.
  • Rule: If a state is invalid, halt immediately with a descriptive error. Do not try to "patch" bad data.
  • Result: Keeps logic simple by never accounting for "half-broken" states.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

code-philosophy is a skill published in the GitHub repository kdcokenny/ocx (978 stars, last pushed 18d ago), licensed MIT. It adds 32 tokens to every session and 687 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
