Nested system-manual reference: the expanded form of the resident substrate prompt — body/extensions, lifecycle states, the `system` tool in practice, communication and memory layers, collaboration topology, MCP/addon ownership, and (§11) the canonical `init.json` composition and preset runtime model. Route via `system-manual` when it is unclear whether this is the right node.
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
# Substrate Manual This is the expanded form of the resident `substrate` prompt — a nested skill-reference owned by `system-manual`, not a top-level catalog skill. Read it when the short resident rule is not enough; route via `system-manual` when it is unclear whether this is the right node. The resident substrate is kernel-owned and cross-app stable. It holds the minimal operating model every LingTai agent must keep resident; this manual expands that model without making the resident layer an operations handbook. ## 1. Body and extensions An agent has one active mind—the LLM turn loop—and several extensions: | Extension | Persistence | Use it for | Do not use it for | |---|---:|---|---| | **Shell (bash)** | One command / job | Deterministic host work: git, tests, scripts, curl, builds, file transforms | Long-lived specialization or social coordination | | **Daemon** | Ephemeral | Context-isolated exploration where you only need the conclusion or artifact | Work that must remember, own a relationship, or persist learning | …

How to install
mdr add lingtai-ai/lingtai-kernel/substrate-manual@sha256:4ca987267de73968The line at the top of this page pins the label v1.5.1, 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.
