semantic-spacetime SKILL.md skillA
semantic-spacetime from magnus919/agent-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add magnus919/agent-skills/semantic-spacetime@git:20260902.035e58dPins git:20260902.035e58d in mdr.lock. Pin the fingerprint instead.

Model and analyze Semantic Spacetime (SST) graphs, distances, trajectories, drift, and model files. Do not use this skill for promise-theory vocabulary and fundamentals without SST modeling; use `promise-theory` for the substrate concepts.
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
# Semantic Spacetime Semantic Spacetime (SST) is Mark Burgess's discrete, graph-theoretic model of meaning over time. A *semantic element* is one autonomous agent plus its scalar promises; a *semantic spacetime* is a collection of such elements in which a local change in state, promises, or configuration is a local unit of time. Time is proper time — there is no global clock (the precedence view Burgess credits to Lamport). Causality is cooperative: every adjacency requires an offer (+) and an acceptance (−) promise on both ends, so space is made of cooperating nodes and edges. The 2025 γ(3,4) formalism types the graph: three node meta-types (events, things, concepts) connected by four link types (0 = NEAR, ±1 = LEADS TO, ±2 = CONTAINS, ±3 = EXPRESSES). Absorbing states in partial graphs leak information, and intentionality enters at the boundary. SST is built on Promise Theory — for the promise vocabulary, load [promise-theory](../promise-theory/SKILL.md) instead of re-deriving it here. This skill is a thin router: load the dense material only when a row in [Load By Need](#load-by-need) matches your task. ## When to use …

How to install
mdr add magnus919/agent-skills/semantic-spacetime@sha256:a26c4db145ec03a4The line at the top of this page pins the label git:20260902.035e58d, 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.
