Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00101 | $0.01014 |
| Opus 5.5 | $0.00040 | $0.00406 |
| Sonnet 5.5 | $0.00020 | $0.00203 |
| Haiku 4.5 | $0.00010 | $0.00101 |
Grade A, and why
save-skill 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 — 56 lines — stays where its author put it; the contents beside it link to each section on GitHub.
학습 스킬을 claude.ai 에 영속화하는 Cowork 전용 흐름입니다. 이 컨테이너의 ~/.claude/skills 는 세션 종료 시 사라지고, 미저장 스킬은 세션 도중에도 주기적 스킬 동기화(약 10분 간격)가 삭제할 수 있으므로(실측 2026-07-16), 증류 직후 바로 이 흐름을 실행하는 것이 안전합니다. 전송 전에 대상 SKILL.md 를 ~/.claude/skills 밖(작업 디렉토리)에도 cp -r 백업해 두면 동기화 삭제에도 복원할 수 있습니다.
1단계 — 대상 결정
인자로 스킬 이름(들)이 주어지면 그 스킬들이 대상입니다. 인자가 없으면 미저장 후보를 자동 감지하세요:
python3 - <<'EOF'
import json, os
skills_dir = os.path.expanduser("~/.claude/skills")
synced = set()
try:
with open(os.path.join(skills_dir, "manifest.json"), encoding="utf-8") as fh:
for s in json.load(fh).get("skills", []):
synced.add(str(s.get("skillId") or ""))
synced.add(str(s.get("name") or ""))
except Exception:
pass
unsaved, saved = [], []
for entry in sorted(os.listdir(skills_dir)):
if entry.startswith("."):
continue
p = os.path.join(skills_dir, entry, "SKILL.md")
if not os.path.isfile(p):
continue
head = open(p, encoding="utf-8", errors="ignore").read(2048)
if "self-improving-skills" not in head and "origin: distilled" not in head:
continue # 학습 스킬만 대상 (plugin/anthropic 스킬 제외)
(saved if entry in synced else unsaved).append(entry)
print("미저장(이번 세션 생성, 세션 종료 시 소실):", unsaved or "없음")
print("저장됨(claude.ai 동기화로 존재):", saved or "없음")
EOF
미저장목록이 기본 대상입니다.저장됨스킬이라도 이번 세션에서 patch 됐다면(사용자가 언급했거나 이 대화에서 수정한 기억이 있으면) 재저장 대상에 포함하세요 — 컨테이너 안의 수정본은 저장하지 않으면 사라집니다.- 대상이 없으면 "저장할 학습 스킬이 없습니다"라고 한 줄 보고하고 끝내세요.
2단계 — 저장 거부 규칙 사전 점검
claude.ai '스킬 저장'이 거부하는 두 패턴을 저장 전에 고치세요 (실측 규칙):
- 예약어: frontmatter
name에claude또는anthropic포함 → 디렉토리명과 name 을 함께 예약어 없는 이름으로 변경 (예:claude-code-hook-diagnostics→cloud-hook-diagnostics). - 꺾쇠 태그:
description에<...>형태(placeholder 포함, 예:mnt/<folder>) → 일반 표기로 변경 (mnt/폴더명). 본문(body)의 꺾쇠는 무방합니다.
3단계 — 전송과 안내
- 각 대상의 SKILL.md 를 SendUserFile 로 보내세요 (caption: 스킬 이름 + 무엇을 하는 스킬인지 한 줄).
- 사용자에게 안내하세요: 파일 카드의 '스킬 저장' 버튼을 누르면 claude.ai 계정에 등록되고, 다음 Cowork/Claude Code 세션 컨테이너에 자동 동기화됩니다.
- 이미 같은 이름이 등록된 스킬을 재저장한 경우: 갱신인지 중복 생성인지는 claude.ai 동작에 따르므로, 저장 후 설정 > 스킬 목록에서 중복이 생겼는지 확인하고 오래된 쪽을 삭제하도록 한 줄 덧붙이세요.
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.

save-skill is a skill published in the GitHub repository UniM0cha/self-improving-skills (51 stars, last pushed 1mo ago), licensed MIT. It adds 101 tokens to every session and 1,014 once invoked, about $0.0004 per session on Opus 5.5. 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 2026-11-07.
