strategic-compact

strategic-compact is a skill for Claude Code, Codex from TeamSPWK/nova. It costs 69 tokens per session (1,693 once invoked), scanned A, original, MIT.

A set of rules for deciding when to shorten or clear an AI coding session's working context. It distinguishes a summary-preserving compaction from clearing context without a summary, and leaves the final action to the user.

In plain words
What is it for?
Use it after planning or design milestones, between unrelated tasks, or at the end of a work phase to decide whether to compact or clear the session.
Why use it?
Long sessions can make earlier details harder to manage, while clearing at the wrong time can lose useful context. The guidance helps choose a safer point for reducing session context.

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

strategic-compact 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 5d 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.

Nova Strategic Compact

세션-수준 컨텍스트 압축 시점을 판단한다. NOVA-STATE 본문 스냅샷 + events.jsonl 분리(v5.44.0+ 상태-수준 모델)와 짝을 이루는 세션-수준 (Claude Code 컨텍스트 창 자체)의 /clear·/compact 적기를 안내한다. Nova 5기둥 중 맥락 기둥의 마지막 한 조각 — 진단(P0-1 컨텍스트 로스트 4원인 카탈로그)에서 자동 안내까지 잇는 출구.

적용 규칙 (on-demand 로드)

  • docs/nova-rules.md §8 세션 상태 유지 — STATE 트림과 세션 압축의 분리
  • docs/nova-rules.md §10 관찰성 계약 — events.jsonl로 후험 검증 가능

핵심 원칙

  1. 상태-수준 ≠ 세션-수준. NOVA-STATE.md 본문 스냅샷 + events.jsonl 단일 진실원(skills/context-chain/SKILL.md, v5.44.0+)은 사람-읽는 인덱스 + 기계-읽는 시계열이지 Claude 컨텍스트 창 압축이 아니다. 둘은 별도 트리거, 별도 효과.
  2. /clear/compact. /clear는 무관 작업 사이 즉시 비움(요약 없음), /compact는 마일스톤 사이 요약 압축. 잘못 쓰면 Generator 컨텍스트가 회복 불가능하게 손실된다.
  3. AI는 제안, 인간은 결정. 본 스킬은 시점 안내만 한다 — /compact·/clear는 사용자가 직접 입력. 자동 실행 금지 (메모리 feedback_evidence_first_identity 정합).
  4. 9 진입점 동결 유지. 본 스킬은 NOVA-STATE 갱신 트리거를 추가하지 않는다 (v5.19.6 state-prune-symmetry 룰 보존).

Evaluator 검증 직전 적대적 검증은 같은 컨텍스트 재현 필요 — 압축 후 검증은 Generator-Evaluator 분리 원칙 훼손
블로커 분석 도중 블로커는 컨텍스트 의존적 — 압축 시 원인 추적 불가능
회귀 테스트 디버깅 도중 실패 메시지·스택은 원본 보존 가치 높음

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.

strategic-compact is a skill published in the GitHub repository TeamSPWK/nova (2 stars, last pushed 4d ago), licensed MIT. It adds 69 tokens to every session and 1,693 once invoked, about $0.0003 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 2026-08-31.
