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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00055 | $0.01906 |
| Opus 5 | $0.00028 | $0.00953 |
| Sonnet 5 | $0.00011 | $0.00381 |
| Haiku 4.5 | $0.00006 | $0.00191 |
Grade A, and why
api-tester scanned grade A with 1 finding 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.

API Tester
프론트엔드 ↔ 백엔드 API 연동을 실제로 검증하는 테스트 스킬.
사용법
"로그인 API 테스트해줘"
"프론트-백엔드 연동 검증해줘"
"/api-tester"
워크플로우
1. 환경 감지
서버 실행 상태 확인:
# 백엔드 포트 확인
curl -s http://localhost:8000/health || curl -s http://localhost:3001/health
# 프론트엔드 포트 확인
curl -s http://localhost:3000 || curl -s http://localhost:5173
프록시 설정 확인 (vite.config.ts, next.config.js, package.json proxy 등):
# Vite 프록시
grep -r "proxy" vite.config.* 2>/dev/null
# Next.js rewrites
grep -r "rewrites\|destination" next.config.* 2>/dev/null
# CRA proxy
grep "proxy" package.json 2>/dev/null
2. CORS 검증
# preflight OPTIONS 요청
curl -v -X OPTIONS http://localhost:8000/api/users \
-H "Origin: http://localhost:3000" \
-H "Access-Control-Request-Method: POST" \
-H "Access-Control-Request-Headers: Content-Type,Authorization" \
2>&1 | grep -i "access-control"
기대 결과:
Access-Control-Allow-Origin: 프론트엔드 origin 포함Access-Control-Allow-Methods: 필요한 HTTP 메서드 포함Access-Control-Allow-Headers: Content-Type, Authorization 포함Access-Control-Allow-Credentials: true (쿠키 사용 시)
3. 인증 흐름 검증
# 로그인 → 토큰 발급
TOKEN=$(curl -s -X POST http://localhost:8000/api/auth/login \
-H "Content-Type: application/json" \
-d '{"email":"[email protected]","password":"test1234"}' \
| jq -r '.token // .access_token // .accessToken')
echo "Token: ${TOKEN:0:20}..."
# 보호된 API 호출
curl -s http://localhost:8000/api/users/me \
-H "Authorization: Bearer $TOKEN" | jq .
# 만료/잘못된 토큰
curl -s -w "\nHTTP Status: %{http_code}\n" \
http://localhost:8000/api/users/me \
-H "Authorization: Bearer invalid-token"
기대 결과:
- 올바른 토큰: 200 + 사용자 정보
- 잘못된 토큰: 401 Unauthorized
- 토큰 없음: 401 또는 403
4. CRUD 엔드포인트 검증
# CREATE
curl -s -X POST http://localhost:8000/api/items \
-H "Content-Type: application/json" \
-H "Authorization: Bearer $TOKEN" \
-d '{"name":"테스트 항목","description":"테스트용"}' | jq .
# READ (목록)
curl -s http://localhost:8000/api/items \
-H "Authorization: Bearer $TOKEN" | jq .
# READ (단건)
curl -s http://localhost:8000/api/items/1 \
-H "Authorization: Bearer $TOKEN" | jq .
# UPDATE
curl -s -X PUT http://localhost:8000/api/items/1 \
-H "Content-Type: application/json" \
-H "Authorization: Bearer $TOKEN" \
-d '{"name":"수정된 항목"}' | jq .
# DELETE
curl -s -X DELETE http://localhost:8000/api/items/1 \
-H "Authorization: Bearer $TOKEN" -w "\nHTTP: %{http_code}\n"
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.
- 4d ago First seen · 234 lines · 55 tokens per session scan A 20c7ab48c8dd
api-tester is a skill published in the GitHub repository Dannykkh/skill-olympus (5 stars, last pushed 3d ago), licensed MIT. It adds 55 tokens to every session and 1,906 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
