simplify

simplify is a skill for Claude Code, Codex from ronaknnathani/relay. It costs 108 tokens per session (1,247 once invoked), scanned A, original, MIT.

A code-cleanup skill that makes recently changed code clearer while preserving its behavior. It looks for needless complexity, duplication, dead code, and misleading names.

In plain words
What is it for?
Use it after implementation or before review to simplify the working code changes.
Why use it?
It reduces the effort needed to understand and maintain a change without altering what the software does.

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

simplify 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 3d 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.

How it starts

The opening of the file, as written. The whole thing — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Simplify

Make a change simpler and clearer without changing what it does. The bar: readable, explicit code over clever, compact code — would a senior engineer call this overcomplicated? Scope is the recently changed code — the working diff (e.g. git diff against the branch point) unless the caller names files. This is quality-only: it does not hunt for bugs (that's review).

Step 0 — the invariant

Preserve functionality. Never change what the code does, only how it does it. Every original feature, output, and behavior stays intact. If a simplification would alter behavior, it is a review or implementation concern, not a simplification — stop and surface it.

Scan — three buckets

Look at the changed code for:

  • Structural — nesting depth ≥ 3, functions longer than ~50 lines, nested ternaries, boolean-flag parameters that select behavior, indirection that only forwards a call.
  • Namingdata/result/temp/foo, names that mislead, names that imply something broader or different than the thing actually is.
  • Redundancy — duplicated logic, dead/unreachable code, unused parameters/variables/fields, over-abstraction (a helper, wrapper, or interface used in exactly one place), defensive code for states an upstream invariant already makes impossible.

The deletion test

For each abstraction or layer of indirection, ask: would removing it concentrate complexity (then keep it — it's earning its keep) or merely relocate it (then remove it — it's not)? A single-use helper usually relocates; inline it. A wrapper that hides a genuinely complex subsystem behind a small interface usually concentrates; keep it.

Two-sided guardrail

Simplifying is a balance, not a race to fewer lines. Pair every "look for" with a "don't":

Look for Don't
reduce nesting and indirection introduce a nested ternary or a dense one-liner
inline a single-use helper inline a helper that names a genuinely complex step
remove a redundant abstraction remove a helpful abstraction that organizes the code
consolidate duplicated logic merge unrelated concerns into one function
clearer names, fewer obvious comments make the code harder to debug or extend

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.

simplify is a skill published in the GitHub repository ronaknnathani/relay (3 stars, last pushed 7d ago), licensed MIT. It adds 108 tokens to every session and 1,247 once invoked, about $0.0005 per session on Opus 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 2026-08-31.
