OpenSpec Propose Skill
When to Invoke
Automatically activate when user:
- •Says "Fix this bug", "Small change", "Quick feature"
- •Asks "Simple fix for [issue]", "Minor update to [component]"
- •Mentions "bug fix", "small improvement", "quick change"
- •Has a Level 0-1 scoped change (small, low risk, no major unknowns)
- •Uses words like: bug, fix, small, quick, simple, minor, lightweight
Specific trigger phrases:
- •"Fix this bug: [description]"
- •"Small change to [component]"
- •"Quick feature: [simple feature]"
- •"Simple fix for [issue]"
- •"Minor update: [description]"
- •"Lightweight change proposal"
Prerequisites:
- •Change is Level 0-1 (small, well-defined)
- •No major unknowns or architectural changes
- •Existing codebase (not greenfield project)
Do NOT invoke when:
- •Complex feature requiring PRD (use BMAD instead)
- •Architectural changes needed (use bmad-architecture-design)
- •Multiple teams coordination (use BMAD)
- •Level 2+ complexity (escalate to BMAD)
- •Greenfield project (use BMAD workflow)
Auto-escalate to BMAD when:
- •Scope grows beyond Level 1
- •Major unknowns emerge
- •Requires cross-team coordination
Mission
Capture small change requests or bug fixes and translate them into concise proposals and task outlines without invoking the full BMAD workflow.
Inputs Required
- •change_request: description of the existing behavior and desired adjustment
- •impact_surface: files, services, or user flows likely affected
- •constraints: timeline, risk, or approvals that bound the solution
Outputs
- •
proposal.mdsummarizing problem, desired behavior, and acceptance signals (template:assets/proposal-template.md.template) - •
tasks.mdlisting actionable steps sized for rapid implementation (template:assets/tasks-template.md.template) - •
specs/spec-delta.mdcapturing ADDED/MODIFIED/REMOVED requirements (template:assets/spec-delta-template.md.template) - •Optional
design.mdscaffolded when deeper technical notes are required
scripts/scaffold_change.py creates this structure in openspec/changes/<change-id>/ using the templates above.
Process
- •Validate Level 0-1 scope using
CHECKLIST.md. - •Run
scripts/scaffold_change.py <change-id>to create the workspace underopenspec/changes/. - •Clarify current vs. target behavior and record feasibility notes in
proposal.md. - •Draft
tasks.mdand populatespecs/spec-delta.mdusing the templates inassets/. - •Highlight dependencies, approvals, and risks, then hand off for review or implementation scheduling.
Quality Gates
Ensure checklist items pass before finalizing. Escalate to BMAD if scope exceeds Level 1 or introduces major unknowns.
Error Handling
- •If information is insufficient, ask for missing context (screenshots, logs, reproduction steps).
- •When risks are high or ambiguity remains, recommend migrating to BMAD discovery-analysis.
