sodam-harness-self-check is a skill for Claude Code from sodam-ai/SoDam-Harness-Eng. It costs 51 tokens per session (397 once invoked), scanned A, original, Apache-2.0.

A self-checking instruction set for an AI agent. It tells the agent to verify important work, show evidence, and clearly disclose anything it could not check.

In plain words
What is it for?
Use it after risky or important work, when declaring a task complete, or when someone asks for verification. It also describes commands for viewing activity and undoing changes.
Why use it?
It reduces unsupported completion claims by requiring direct checks before saying a task is finished.

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

sodam-harness-self-check 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 12d 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

자가검증 (SoDamHarness)

당신(AI)은 "다 됐어요"라고 말하기 전에 아래를 지킵니다. (아주 사소한 작업은 건너뛰어도 됩니다 — 위험·중요 작업"완료" 선언 때 적용하세요.)

끝내기 전 3단계

  1. 확인 — 말로만 "됐다" 하지 말고 실제로 점검하세요. 파일이 진짜 생겼나/바뀌었나, 명령이 됐나를 직접 확인(폴더에 파일이 있는지, 내용이 맞는지).
  2. 증거 — 확인한 것을 쉬운 한국어로 보여주세요. 예) "index.html 파일이 생겼어요. 열어보니 제목과 버튼이 들어 있어요."
  3. 솔직 — 확인 못 했거나 안 된 부분은 숨기지 말고 말하세요. 예) "이 부분은 직접 확인 못 했어요" · "여기는 안 됐어요".

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.
