evolve

evolve is a skill for Claude Code, Codex from KirSsuRyu/venom. It costs 93 tokens per session (1,690 once invoked), scanned A, original, MIT.

A skill for updating the Venom project harness when repeated mistakes, coding patterns, project changes, or user corrections reveal that its guidance needs to evolve. The harness is the project's collection of rules, skills, hooks, and notes.

In plain words
What is it for?
It helps strengthen rules, extract repeatable skills, add safety hooks, record decisions, and update build or test guidance.
Why use it?
It turns recurring lessons and changed project practices into lasting instructions instead of relying on someone to remember them.

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

evolve 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.

진화 스킬 — Venom의 자기 성장 엔진

이 스킬은 Venom을 살아있게 만드는 핵심이다. 프로젝트에서 일하면서 발견한 것을 규칙·스킬·hook·메모리로 응결시킨다.

트리거

  • 같은 태그의 실수가 mistakes.md에 2회 이상 기록됨
  • 같은 패턴의 코드를 3회 이상 작성함
  • 사용자가 관례를 교정해 줌 ("항상 이렇게 해", "그렇게 하면 안 돼")
  • 프로젝트 구조가 변경됨 (새 모듈, 새 의존성, 빌드 명령 변경)
  • 사용자가 명시적으로 진화를 요청함

진화 유형 판단

무엇을 진화시킬지 판단하는 기준:

상황 진화 대상 이유
같은 실수 반복 규칙 강화 또는 hook 신규 조언으로 안 되면 강제로
같은 작업 반복 스킬 추출 절차를 한 번에 따를 수 있도록
비자명한 사실 발견 메모리 기록 다음 세션에 전달
관례 교정 규칙 추가 영구적 행동 변경
아키텍처 결정 메모리 ADR 왜 그렇게 했는지 기록
위험 행동 감지 hook 추가 결정적으로 차단
빌드/테스트 변경 규칙 + 스킬 갱신 도구 명령 최신화

절차

1. 분석 — 무엇이 진화를 요구하는가

a) 트리거 원인을 한 줄로 적는다
b) 기존 규칙/스킬/hook 중 관련된 것이 있는지 확인한다
c) 새로 만들지, 기존을 보강할지 결정한다
   - 원칙: 기존 파일 보강 > 새 파일 생성

2. 기존 파일 보강 (기존 것이 있을 때)

a) 대상 파일을 읽는다
b) 추가할 내용을 정한다
c) Edit으로 추가한다
d) 변경 이유를 lessons.md 또는 decisions.md에 기록한다

3. 새 규칙 생성

a) 배치 위치 결정:
   - 기존 규칙 파일 보강 가능 → 기존 파일에 추가 (최우선)
   - 새 파일이 필요 → .claude/rules/evolved/<이름>.md
     (기존 00-55 번호 prefix 파일은 flat 유지, 진화 생성분은 evolved/)

b) 규칙 파일 작성:
   - 제목: # <규칙 영역>
   - 섹션별로 *무엇을* *왜* 해야 하는지 명시
   - 예제 포함 (좋은 예 vs 나쁜 예)

c) CLAUDE.md의 부록 테이블에 등재한다

d) decisions.md에 ADR로 남긴다

4. 새 스킬 생성

a) .claude/skills/evolved/<이름>/SKILL.md 생성
   (기존 기반 스킬은 skills/<name>/ 유지, 진화 생성분은 evolved/ 아래)

b) 형식:
   ---
   name: <kebab-case-이름>
   description: <트리거 조건, 한 줄>
   ---
   # <제목>
   <왜 필요한가>
   ## 절차
   1. ...
   ## 안티 패턴
   - ...

c) 실제 상황에 적용해본다 (머릿속 시뮬레이션이라도)

5. 새 hook 생성

a) .claude/hooks/evolved/<이름>.sh 작성
   - #!/usr/bin/env bash
   - set -euo pipefail
   - stdin에서 JSON 읽기
   - 차단 시 JSON 출력, 통과 시 exit 0
   (기존 기반 훅 flat 파일은 그대로 유지, 진화 생성분은 evolved/ 아래)

b) bash -n 문법 검증

c) chmod +x 부여

d) settings.json의 적절한 이벤트에 등록
   예: "$CLAUDE_PROJECT_DIR"/.claude/hooks/evolved/<이름>.sh

e) JSON 유효성 검증:
   python3 -c "import json; json.load(open('.claude/settings.json'))"

f) 대표 입력으로 스모크 테스트:
   echo '{"tool_name":"Bash","tool_input":{"command":"<테스트명령>"}}' \
     | bash .claude/hooks/evolved/<이름>.sh

g) decisions.md에 ADR로 남김

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.

evolve is a skill published in the GitHub repository KirSsuRyu/venom (5 stars, last pushed 4mo ago), licensed MIT. It adds 93 tokens to every session and 1,690 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.
