coding-simplification

coding-simplification is a skill for Claude Code, Codex from evoelsewhere/evoflux. It costs 78 tokens per session (771 once invoked), scanned A, original, Apache-2.0.

Use this skill to refactor existing code for clarity or reduced duplication without changing its observable behavior — deep nesting, boolean-flag parameters, generic names, or duplicated logic. It requires understanding why the current shape exists before changing it and proving behavior is unchanged; do not use it to…

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

coding-simplification 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 today.

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 — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Simplify existing code

Preserve behavior exactly; simplification is a clarity change, not a feature or a bug fix. Do not load bundled references when this skill activates.

Understand before changing

  1. State what the code currently does, including behavior that looks accidental — an existing edge case, ordering, or error path may be load-bearing even without a visible reason. Do not remove it without understanding why it is there (Chesterton's Fence): if the reason is unclear from code, tests, and history, name the uncertainty instead of deleting silently.
  2. Scope the change to what motivated it. Do not restyle unrelated code in the same file, rename unrelated symbols, or introduce an abstraction the current requirement does not need.
  3. Read references/simplification-signals.md for concrete shape-to-refactor mappings and the codemod threshold.

When the code's current callers or the reason a pattern exists is not evident from the visible source, call code_context with action="search" once using the behavior or literal in question. Skip search when the exact symbol is already known.

For an exact symbol being simplified, use code_context to confirm direct callers/references so the refactor's public shape is preserved for every caller. Start at depth 1. Once the symbol and its callers are known, make the graph the next structural observation instead of continuing broad discovery.

Keep refresh=true for the first indexed query and after edits. Use refresh=false only for an immediate follow-up that intentionally reuses the same index version.

Read references/code-context-contract.md only after a result exposes ambiguity, cross-repository scope, or another static fallback gap.

Simplify

Prefer clarity over cleverness and follow the file's existing conventions over a personally preferred style. Do not introduce a generic abstraction to replace a handful of concrete, similar lines; three similar lines are often clearer than a premature parameter or interface. For a refactor spanning more than roughly 500 lines, prefer a codemod/AST-based transform over manual edits so the change stays mechanical and reviewable.

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

coding-simplification is a skill published in the GitHub repository evoelsewhere/evoflux (7 stars, last pushed today), licensed Apache-2.0. It adds 78 tokens to every session and 771 once invoked, about $0.0004 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 2026-09-05.
