A release-checking workflow for completing one planned slice of an engineering project. It runs the plan's checks, audits affected areas, records the results in HARNESS.md, and marks the plan complete only when all conditions pass.

It helps close planned work involving system boundaries, frame loops, bridges, or public APIs, with targeted audits and recorded verification results.

It prevents unfinished or unverified work from being treated as complete. Failed checks remain visible in the active plan instead of being hidden.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00033	$0.00234
Opus 5	$0.00016	$0.00117
Sonnet 5	$0.00007	$0.00047
Haiku 4.5	$0.00003	$0.00023

Measured 6d ago against content hash 2d2b0df71417, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-12, from the pricing page.

Security

Grade A, and why

close-epoch 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.

What it actually says

Close Epoch

plan의 검증 섹션 명령을 실제로 실행한다. 미실행을 성공으로 보고하지 않는다.
변경 영역에 해당하는 감사 서브에이전트만 실행한다(전부 돌리지 않는다): boundary/invariant 변경 → invariant-guard, 프레임 루프·브리지 → frame-perf-auditor, public API → api-surface-guard. 확정 위반만 수정 후 해당 검증 재실행, 의심은 보고에 추정으로 남긴다.
plan 완료 조건을 실제 결과로 갱신하고 HARNESS.md에 라운드를 append한다(변경 boundary, 실행한 검증과 결과, 다음 slice 한 줄).
완료 조건 전부 충족 시에만 plan을 completed/로 이동한다. 아니면 active에 남기고 실패를 plan에 기록한다.

Changes

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.

close-epoch is a skill published in the GitHub repository jigglypop/gaesup-world (22 stars, last pushed yesterday), licensed MIT. It adds 33 tokens to every session and 234 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 2026-09-06.
