flow-next-capture

flow-next-capture is a skill for Claude Code, Codex from gmickel/flow-next. It costs 30 tokens per session (3,370 once invoked), scanned A, original, MIT.

A tool that turns a conversation about a proposed change into a written software specification.

In plain words
What is it for?
Use it to capture an idea as a draft specification, review its source details, and approve it for further planning.
Why use it?
It preserves decisions and requirements so later planning work does not depend on remembering the conversation.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

flow-next-capture scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 169 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/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.

Ask the user via plain text. Render the options below as a numbered list 1.N., followed by a final option N+1. Other — type your own answer. Print the question, then the numbered list, then stop and wait for the user's next message before continuing. Parse the reply as: a bare number 1N+1 → that option; the literal text of an option label → that option; free text after Other → custom answer.

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] / [strategy:<track>]), prints the full draft as ordinary markdown then issues a short approval ask (print-then-ask — never embed multi-paragraph drafts in plain-text numbered prompt 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 thin spec plumbing (spec create, spec set-plan, optional spec set-branch, memory search for duplicate detection) plus the chart handoff callback (chart link-spec) after a successful chart-briefing capture. Capture never writes chart files and never mutates a chart's ready flag; chart never writes .flow/specs.

Routing boundary (fn-135 / guide matrix)

Clear meaningful ideas and finished chart briefings route here - to capture (or direct spec authoring). Capture does not manufacture a chart for clear work. When intent and boundaries are already stateable, skip chart (signal absent). After a structured brief lands, narrow or skip interview only once read-back proves no material gaps - never pre-skip interview on hope. Unsure: /flow-next:guide.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

flow-next-capture is a skill published in the GitHub repository gmickel/flow-next (691 stars, last pushed today), licensed MIT. It adds 30 tokens to every session and 3,370 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
