What OpenSpec Sync Specs does

OpenSpec Sync Specs updates main OpenSpec specification files with changes from a delta spec, handling added, modified, removed, and renamed requirements. Use it when a change’s delta specs need to be merged into the main specs without archiving the change.

OpenSpec Sync Specs is cataloged under Automation on DirSkills. OpenSpec Sync Specs comes from a repository tagged agent-teams, ai, ccg, claude-code and cli.

Documentation

README

Excerpt

Sync delta specs from a change to main specs.

This is an agent-driven operation - you will read delta specs and directly edit main specs to apply the changes. This allows intelligent merging (e.g., adding a scenario without copying the entire requirement).

Input: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.

Steps

If no change name provided, prompt for selection

Run openspec list --json to get available changes. Use the AskUserQuestion tool to let the user select.

Show changes that have delta specs (under specs/ directory).

IMPORTANT: Do NOT guess or auto-select a change. Always let the user choose.
