close

# Session Close > **Deprecated.** This skill is superseded by [[skills/context-capsule/SKILL.md|/context-capsule]] (docs/two-verb-lifecycle.md). New installs should reach for `/context-capsule`; this file stays for anyone still invoking `/close` by habit during the transition. Run the aigent-OS end-of-session memory commit inline. The close must be idempotent: rerunning it after a partial failure must not duplicate ledger entries, capsules, or session summaries. All operator-owned durable state lives under `vault/`. Framework indexes such as `memory/SKILL_LEDGER.md` remain outside the vault and are not session memory. ## Hardened compatibility contract The active two-verb lifecycle does not run a second close ceremony, but manual `/close` keeps the same shared postconditions as nightly: - exact already-authored decision outcomes append only through `daemons/nightly-decision-outcome.mjs`, with a unique decision/interval match and compare-and-swap; - bounded Session Log or Active Priorities trimming runs only through `skills/context-hygiene/SKILL.md`, archives before removal, and must end in `CONTEXT_HYGIENE PASS`; - Dream synthesis follows `skills/dream/SKILL.md` and must end in `DREAM_CONTRACT PASS`; - cognitive changes follow `skills/cognitive-update/SKILL.md` and must end in `COGNITIVE_CONTRACT PASS`; - missing canonical input is failure, not "nothing to do"; - judgment-bearing measurement entries are staged through `skills/nightly-ledger-capture/SKILL.m...
