simplify

When user uses /simplify slash command, review recently changed code for safe simplifications (dead code, redundant logic, naming, types), show every proposed change with before/after, and apply only after explicit user approval.

Made for: Claude Code.

Per session 48 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 1,078 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin unknown No closer match found in the catalogue.
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 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 — 153 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/simplify — Code Simplification

When the user invokes /simplify [scope], review code for safe simplifications and apply them with user approval.

Command Scope What gets reviewed
/simplify uncommitted Staged + unstaged changes (default)
/simplify HEAD~N recent commits Changes in the last N commits
/simplify <file> single file Only that file

Workflow

1. Determine Scope

Default to uncommitted changes when no argument is provided.

git status --short --branch

For uncommitted changes:

git diff --staged --name-only
git diff --name-only

For commit range (e.g., HEAD~3):

git diff HEAD~3 --name-only

For a single file, verify it exists and read it.

Stop if:

  • no changed files in the requested scope
  • merge conflicts are present

2. Read And Analyze

Read the full content of each changed file (not just the diff) so that simplifications are informed by surrounding context.

Look for:

Category Examples
Dead code Unused imports, unreachable branches, commented-out blocks, unused variables/functions
Redundant logic Duplicate conditions, double negation, unnecessary else after return, if x return true else return false
Naming Misleading names, single-letter variables in non-trivial scope, inconsistent conventions within the file
Type tightening Overly broad types (any, interface{}), missing return types, unnecessary type assertions
Unnecessary wrappers Trivial wrapper functions, redundant intermediate variables, over-abstracted single-use helpers
Simplifiable expressions Ternaries that can be boolean expressions, verbose null checks replaceable by optional chaining, long-form iterations replaceable by standard library calls

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 command published in the GitHub repository n9e/fe (302 stars, last pushed today), licensed Apache-2.0. It adds 48 tokens to every session and 1,078 once invoked, about $0.0002 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 2026-09-01.
