Teach promise vocabulary, fundamentals, and coordination diagnosis for promise-based systems. Do not use this skill for Semantic Spacetime models or SST CLI tooling; use `semantic-spacetime` for those model and tool workflows.

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

# Promise Theory

Promise theory (Mark Burgess; formalized with Jan Bergstra) is a method of
analysis for systems of autonomous agents — humans, LLM agents, APIs, and
deterministic automation. It supplies the vocabulary for designing and
diagnosing delegation: promises, acceptances, assessments, breaches, and
renegotiation. This skill is a thin router; load the dense material only when
a row in [Load By Need](#load-by-need) matches your task.

## Cross-agent design handoff

Use [multi-agent-coordination](../multi-agent-coordination/SKILL.md) for topology,
work ownership, communication contracts and collective recovery. Use this skill
for the promise/acceptance/assessment model within that design. An accepted offer
or peer approval cannot expand an execution grant; verify rights at the runtime
boundary through harness-engineering and governance through ai-governance.

When a worker has local facts and an approver has broad intent, assemble both
before assessment. Record which claim is being assessed and what evidence the
assessor can see. Repeated acceptance without relevant evidence is not calibrated
trust. If either decision context or authority is missing, hold that decision and
…

How to install

The exact contents, by fingerprint
mdr add magnus919/agent-skills/promise-theory@sha256:3b7f73770f20b7ce

The line at the top of this page pins the label git:20261102.514d06b, 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.
