Project Roadmap Manager

Maintain ROADMAP.md in the project root as the canonical roadmap record. Prefer updating existing sections over appending duplicates, and keep Current Milestone synchronized with the latest accepted plan.

Workflow

1. Identify project root and target file:
   • Use <project_root>/ROADMAP.md.
   • If root is ambiguous, infer from repository root.
2. Ensure ROADMAP.md exists:
   • If missing, create it using the template in this skill.
3. Classify the request into one of these event types:
   • Project bootstrap.
   • Plan acceptance/completion.
   • Milestone/version roadmap set or changed.
   • Milestone reached/blocked/de-scoped.
   • Roadmap reference/query.
4. Apply the event-specific update rules.
5. Keep all sections internally consistent:
   • Current Milestone matches active milestone in Milestones.
   • Plan History includes accepted plan snapshots.
   • Change Log captures each roadmap mutation with date and reason.

ROADMAP.md Template

Use this structure when creating a new roadmap:

# Project Roadmap

## Current Milestone
- ID: M1
- Name: Initial Setup
- Status: Planned
- Target Version: v0.1.0
- Last Updated: YYYY-MM-DD
- Summary: One-paragraph summary of the currently accepted plan.

## Milestones
| ID | Name | Target Version | Status | Target Date | Notes |
| --- | --- | --- | --- | --- | --- |
| M1 | Initial Setup | v0.1.0 | Planned | YYYY-MM-DD | Bootstrap milestone |

## Plan History
### YYYY-MM-DD - Accepted Plan (v0.1.0 / M1)
- Scope:
- Acceptance Criteria:
- Risks/Dependencies:

## Change Log
- YYYY-MM-DD: Initialized roadmap.

Event Handling Rules

Project Bootstrap

• Create ROADMAP.md if absent.
• Add an initial milestone (M1 unless user provides a different identifier).
• Add a changelog entry indicating roadmap initialization.

Plan Acceptance or Completion

• Update Current Milestone to reflect the accepted plan.
• Add or update corresponding row in Milestones.
• Append an Accepted Plan entry in Plan History with scope and acceptance criteria.
• Add a changelog entry summarizing what changed and why.

Milestone or Version Roadmap Set/Update

• Update existing milestone by ID/version if it exists.
• Add milestone only when no matching milestone exists.
• Avoid duplicate milestones for the same ID or target version.
• If the updated milestone is active, sync Current Milestone.

Milestone Reached/Changed

• Update milestone status (Completed, In Progress, Blocked, De-scoped, or Planned).
• Update Current Milestone if active milestone changed.
• Add a dated note in Change Log that captures transition and reason.

Roadmap Reference Requests

• Point explicitly to <project_root>/ROADMAP.md.
• Cite the relevant section name (Current Milestone, Milestones, Plan History, or Change Log).
• If file is missing, create it first, then reference it.

Quality Bar

• Preserve existing useful roadmap content.
• Use ISO date format (YYYY-MM-DD) for all dated fields.
• Keep edits minimal and deterministic.
• Never leave conflicting milestone statuses across sections.
