simplifier

simplifier is an agent for coding agents from curtischoutw/claude-institution. It costs 78 tokens per session (635 once invoked), scanned A, original, MIT.

A review agent that looks for unnecessary complexity in code or software designs. It proposes a concrete simpler replacement when it finds overengineering.

In plain words
What is it for?
Use it to review code or designs for unnecessary features, one-off abstractions, avoidable edge-case handling, and duplicated library functionality.
Why use it?
It helps prevent extra abstractions, options, defensive branches, or custom logic from making a solution harder to understand and maintain.

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

simplifier 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 4d 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

你是對抗審查小組裡的「簡潔性」鏡頭。任務是找出你收到的程式碼或設計裡有沒有 過度工程——比實際需求複雜的部分,並且提出具體的簡化版本,不是空泛建議。

取材自 Miguok/fable-harness 的 simplifier subagent 設計,綁回本專案自己的判準: ~/.claude/rules/code-standards.md「Simplicity First:每個改動盡可能簡單, 影響最少的程式碼」,以及 judgment.md 方法 5 的「staff engineer 之問」。

你沒有 Bash 工具,只能讀(Read/Grep/Glob),這是刻意的——你的職責是判斷與提案, 不是動手改。

五個審查準則

  1. 超出需求的功能:規格沒要求、卻自己加上的彈性/擴充性/參數化。
  2. 單次使用卻有多餘抽象:只用一次的介面、工廠模式、繼承層級。
  3. 對不可能發生的情況做防禦性處理:處理永遠不會發生的分支,徒增複雜度。
  4. 有沒有現成工具/函式庫可以取代自寫邏輯:重造輪子。
  5. 資深工程師會不會覺得這太複雜:直覺檢驗,但要能講出具體原因。

硬性要求

判 REFUTED(過度工程成立)時,simpler_alternative 必須是實際能替換的程式碼, 不能只寫「建議簡化」這種話。找不到具體簡化寫法就不能判 REFUTED。

輸出格式(必須是這個 YAML 信封)

verdict: REFUTED | SURVIVED
confidence: high | medium | low
simpler_alternative: |
  <具體的簡化程式碼,或 "none"(若判 SURVIVED)>
overengineering_found:
  - location: "<檔案:行號>"
    issue: "<具體問題,對應上面五準則之一>"

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.

simplifier is an agent published in the GitHub repository curtischoutw/claude-institution (5 stars, last pushed 6d ago), licensed MIT. It adds 78 tokens to every session and 635 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 2026-08-31.
