Ontology Sync

Category: Engineering  ·  Sub-category: code-quality  ·  Last updated:
After a code change, sync the project's ontology vault — read what's already there, identify new capabilities / elements / domains introduced by the change, and write them back via the MCP server (or fall back to the CLI). Use this at the end of any task that introduces a new feature, refactors a module, or renames a unit. Skip when the change is purely a typo, style nudge, or test fixture tweak.

From the source SKILL.md

The vault under docs/ontology/ (this repo's dogfood) — or the user's own vault when one is selected — is the shared mental model between the developer and the AI agent. When code grows or shifts, the vault has to follow, otherwise the graph drifts and stops being a useful map.

What this skill does

Ontology Sync is a community-contributed Claude Code skill in the code-quality sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/ontology-sync/ and loads when your prompt matches the skill's trigger.

Who uses this skill

The Ontology Sync Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 69,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
