Curate Sandwalk's persistent Memory (USER.md, MEMORY.md, Specialist PRIORS.md), Living Markdown Wiki ([[wikilinks]]), and Knowledge Graph (Omnigraph cookbooks, SPIKE signals/insights, and supporting vs. contradicting claims).
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
# Knowledge & Memory Steward Use this skill when capturing durable knowledge from a research, engineering, or analysis session, when organizing a project's Living Wiki, or when modeling structured claims and evidence in Sandwalk's Knowledge Graph. ## 1. Choose the Right Knowledge Tier Sandwalk separates knowledge into three distinct tiers so the system prompt stays fast and bounded while deep domain context remains one tool call away: 1. **Bounded Snapshot Memory (`memory.mutate` -> `USER.md`, `MEMORY.md`, `PRIORS.md`)**: - **Purpose**: Compact facts that must be present at the start of every session without a search round-trip. - **`target="user"` (`USER.md`, ~1,375 chars)**: User identity, communication style, preferred stack, plotting/citation conventions. - **`target="memory"` / `"project"` (`MEMORY.md`, ~2,200 chars)**: Environment facts, dataset caveats (e.g., *"Exclude sample_04 due to low read depth"*), architectural decisions, and verified tool workarounds. - **`target="specialist"` (`PRIORS.md`)**: Persona cognitive priors, skepticism heuristics, and methodological biases for the active Specialist. …

How to install
mdr add fastfold-ai/sandwalk/knowledge-steward@sha256:f5835d5c72f754f6The line at the top of this page pins the label v1.0.0, 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.
