Use between workflow phases or when context feels bloated. Writes a structured checkpoint capturing task, findings, files, state, and next steps, then continues from that summary instead of the full history. Invoke standalone or automatically between quest phases.
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
# Lembas — Intentional Context Compression ## Overview Compresses the current conversation into a structured summary to keep the context window in the "smart zone." This is the intentional compaction pattern from context engineering — proactively trimming context between phases rather than waiting for overflow. Reasoning quality degrades as a context window fills — well before it overflows. This skill is the mechanism for staying in the sweet spot by compacting early and often. ## When to Use - Between phases of the quest workflow (invoked automatically by `/quest`) - After any stretch of verbose output you would not re-read (build logs, long file reads, exploratory searches, failed-attempt noise) — if in doubt, compact - Before switching focus within a session - Standalone via `/lembas` ## Process ### Step 1: Identify Current Phase Determine what just completed: - **Research:** Understanding the system, identifying files - **Plan:** Outlining steps, getting approval - **Implement:** Writing code, running tests - **Review:** Adversarial review, conventions, verification, PR - **Ad hoc:** No formal phase — general work ### Step 2: Extract Essentials …

How to install
mdr add justinjdev/fellowship/lembas@sha256:f86190fd85701b7eThe line at the top of this page pins the label git:20260906.bd1e158, 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.
