/flow-next:capture — agent-native conversation → spec

A free-form discussion (or a /flow-next:prospect survivor) frequently produces enough material for a complete spec, but stops short of the formal flowctl spec create + spec set-plan heredoc documented in CLAUDE.md. Without an explicit synthesis step, that context decays — the next session loses the conversation, the spec never lands, and the user re-explains the same idea to /flow-next:plan.

This skill IS the synthesis. The host agent (Claude Code / Codex / Droid) extracts the recent user turns, drafts a CLAUDE.md-shaped spec with per-line source tags ([user] / [paraphrase] / [inferred]), shows the full draft back via AskUserQuestion, and only then writes the spec via existing flowctl plumbing. There is no Python synthesizer, no codex / copilot subprocess, no fast-model classifier. The host agent is already an LLM and does the work directly.

flowctl provides only thin spec plumbing (spec create, spec set-plan, optional spec set-branch, memory search for duplicate detection). No new flowctl subcommands.

Read workflow.md for the full phase-by-phase execution. Read phases.md for the must-ask cases lookup, source-tag taxonomy, confidence tiers, and forbidden-behaviors list.

CRITICAL: flowctl is BUNDLED — NOT installed globally. which flowctl will fail (expected). Always use:

FLOWCTL="${DROID_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}/scripts/flowctl"

Inline skill (no context: fork) — AskUserQuestion must stay reachable across phases. Subagents can't call blocking question tools (Claude Code issues #12890, #34592). Phase 0 (duplicate detection) and Phase 4 (read-back loop) both require user choice in interactive mode. (sync-codex.sh rewrites AskUserQuestion to request_user_input in the Codex mirror.)
