# /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]`), **prints the full draft as ordinary markdown then issues a short approval ask** (print-then-ask — never embed multi-paragraph drafts in `AskUserQuestion` bodies), 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](workflow.md) for the full phase-by-phase execution. Read [phases.md](phases.md) for the must-ask cases lookup, source-tag taxonomy, confidence tiers, and forbidden-behaviors list.** ## Preamble **CRITICAL: flowctl is BUNDLED — NOT installed globally.** `w...
