A command that downloads all scene videos and joins them into one video, with optional text-to-speech narration. TTS converts written text into spoken audio.

Use it after creating scene videos when you need one concatenated video, optionally accompanied by generated narration.

It removes the manual work of collecting separate scene clips and combining them into a finished video.

How crisng95/flowkit configures Claude Code

About the project

FlowKit is a standalone system that uses a Chrome extension to connect AI agents to Google Flow for generating images and videos, including text-to-video and image-to-video work. It is for people who want to create video content through Google Flow rather than operate its web interface manually. The catalogue entries provide commands and instructions for working with FlowKit.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.00054
Opus 5.5	$0.00000	$0.00022
Sonnet 5.5	$0.00000	$0.00011
Haiku 4.5	$0.00000	$0.00005

Security

Grade A, and why

fk-concat 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 2mo 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.

Changes

What this file has done since we first saw it

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.
