Session opening ritual. Loads context via L0→L1 protocol, displays briefing with active decisions and pending items, checks for stale artifacts by priority. Triggers: "start session", "what's the context", "where were we", "catch me up".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# /session-start Load context. Display briefing. Flag staleness. Get to work. ## Steps ### 1. Load L0 — Session Continuity Read `NEXT.md` in the project root. ### 2. Load L1 — Project Context (~600 tokens) Read (skip if missing): - Project `AGENTS.md` - Vault `_context.md` — **top 3 sections only**: Summary + Key Numbers + Active Reasoning Artifacts table. STOP before Doc Index / Decision Log / Open Questions / Related sections. This is the L1 partial read rule. - Peer Card (`People/Self.md` in vault or memory folder) — structured user profile with communication style, decision patterns, strengths, growth areas. Load the **Communication Style** and **Decision Patterns** tables only (~20 lines). Template provided in starter vault. Skip if missing — suggest creating one on first session. ### 3. Seed Activation Check Scan `[S]` entries in the Active Reasoning Artifacts table: - If activation condition appears met → surface in briefing under "Seeds Ready" - If dormant > 90 days → flag for review - When a seed activates, suggest: "This seed is ready. Want to `/decide` on it?" ### 4. Staleness Check Scan `[D]`, `[I]`, `[E]` entries in the Active Reasoning Artifacts table: …

How to install
mdr add aiyo28/memento-os/session-start@sha256:c13fbb3fb839f1dcThe line at the top of this page pins the label v2.0.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
