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 5.1 | $0.00049 | $0.00453 |
| Opus 5 | $0.00024 | $0.00227 |
| Sonnet 5 | $0.00010 | $0.00091 |
| Haiku 4.5 | $0.00005 | $0.00045 |
Grade A, and why
handoff 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 6d 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.

HANDOFF.md란?
컨텍스트 리셋 전에 작업 상태를 기록하는 파일입니다. 새 세션에서 이 파일만 읽으면 바로 이어서 작업할 수 있습니다.

사용 시점
- 컨텍스트가 80-100k 토큰에 도달했을 때
- /compact 3번 사용 후
- 작업을 며칠 쉬기 전
- 복잡한 작업 중간에
새 세션에서 "HANDOFF.md 읽고 이어서 작업해줘"라고 하면 됩니다.
HANDOFF.md 크기 가이드라인
- 최대 100줄, 3000자 이내 목표
- 코드 스니펫은 최소한으로 (파일 경로만 기록)
- 핵심 컨텍스트만 기록, 세부사항은 코드에서 확인
- 새 세션의 초기 토큰 소비를 줄여 캐시 워밍업 비용 절약
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.

handoff is a skill published in the GitHub repository jh941213/codex-lattice (19 stars, last pushed 3mo ago), licensed MIT. It adds 49 tokens to every session and 453 once invoked, about $0.0002 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 2026-08-30.
