simplicity-review

simplicity-review is a command for coding agents from naimkatiman/continuous-improvement. It costs 53 tokens per session (429 once invoked), scanned A, original, MIT.

A command that reviews the current code changes for unnecessary complexity and reports whether they should be kept or trimmed without editing the files.

In plain words
What is it for?
Use it before shipping a change to inspect the diff, locate over-built sections, and receive file-and-line suggestions for simpler alternatives.
Why use it?
Passing tests shows that code works, but not that it is as small or simple as it could be. The review checks for existing code, standard-library features, platform features, or shorter solutions to reuse.

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

simplicity-review 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 5d 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.

What it actually says

/simplicity-review — Judge the Diff Before You Ship It

Read the current change like the laziest senior dev in the room: could this have been smaller? Passing tests prove correctness, not minimality. Backed by the simplicity-review skill.

What it does

Takes the working-tree diff (vs HEAD by default; accepts an optional commit range or file list), reads each changed block, and walks a fixed reuse ladder:

1. Does this need to exist?   -> skip it (YAGNI)
2. Already in this codebase?  -> reuse it
3. Stdlib does it?            -> use it
4. Native platform feature?   -> use it
5. Installed dependency?      -> use it
6. One line?                  -> one line
7. Only then:                    the minimum that works

It reports file:line, what is over-built, the specific simpler path, and closes with GO (already minimal) or TRIM (findings to apply). It does not edit code.

Default skeptical

A finding is a hypothesis. Read the surrounding code and prove the simpler path exists and preserves behavior before asserting it; a wrong trim is worse than the over-build. Never flag input validation, data-loss-preventing error handling, security, or accessibility — lazy, not negligent.

Pairs with

  • simplicity-review skill — the discipline this command runs.
  • proceed-with-the-recommendation — apply the trims under the 7 Laws.
  • verification-loop — the ladder to re-run on whatever you trim.
  • production-readiness-review — the sibling diff review for performance, security, UI, and test coverage.

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.

simplicity-review is a command published in the GitHub repository naimkatiman/continuous-improvement (7 stars, last pushed 10d ago), licensed MIT. It adds 53 tokens to every session and 429 once invoked, about $0.0003 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.
