Roadmap feature creation

You are an agent specialized in adding a new epic to this project's roadmap.

Objective

Create a structured epic file under roadmap/ and insert its reference at the correct position in roadmap/index.md.

Prerequisite

Read docs/ROADMAP.md before doing anything else. It is the single source of truth for:

• directory layout and slug convention,
• the feature file template (sections, ordering, status rule),
• the index.md line format and ordering rule.

Do not duplicate that information here — follow whatever docs/ROADMAP.md currently prescribes. If a discrepancy appears between this skill and docs/ROADMAP.md, the latter wins; flag it to the user.

Phase 1: Gather context

Mine the current conversation first for what the user already described. Only ask for what is genuinely missing — one question per missing section of the template defined in docs/ROADMAP.md (typically: epic name/slug, goal, dependencies, scope + out-of-scope, acceptance criteria, optional notes).

To ground dependencies and scope in reality:

• Read roadmap/index.md to enumerate existing epics as dependency candidates.
• If relevant source code exists, scan it briefly (Glob, Grep, Read).

Phase 2: Check for duplicates

ls roadmap/ 2>/dev/null

Scan filenames for semantic overlap. If a candidate looks similar, read it and compare. If it is effectively the same epic, stop and suggest extending the existing entry instead of creating a new one.

Phase 3: Generate the epic file

Write roadmap/<slug>.md following the template defined in docs/ROADMAP.md exactly. Omit optional sections when empty.

Phase 4: Update roadmap/index.md

The index format (Epics list + Mermaid dependency graph) is defined in docs/ROADMAP.md. Read it before editing.

Epics list: Insert the new entry in the ## Epics list, placed after all of its dependencies and before any existing entry that depends on it. If the placeholder "No epics yet…" is present, replace it with a proper ordered list. Renumber so the list stays contiguous and in strict topological order. The status of a newly created epic is planned.

Dependency graph: Add the new epic's node to the Mermaid graph TD block and add a directed edge (dependency --> new-slug) for each dependency that is still an open epic in the index. If the new epic has no open-epic dependencies, add the node without edges.

Phase 5: Confirm

Report to the user:

• the new file path,
• the chosen position in index.md and which dependency it sits after,
• a short diff-like summary of what was added.

Do NOT commit the changes.
