Generate and stitch short videos via Google Veo 3.x using the Gemini API (google-genai). Use when you need to create video clips from prompts (ads, UGC-style clips, product demos) and want a reproducible CLI workflow (generate, poll, download MP4, optionally stitch multiple segments).

What this skill does


# Veo 3 Video Generation (Gemini API)

Use the bundled script to generate an MP4 from a text prompt.

## Generate (text → video)

```bash
uv run {baseDir}/scripts/generate_video.py \
  --prompt "A close up of ..." \
  --filename "out.mp4" \
  --model "veo-3.1-generate-preview" \
  --aspect-ratio "9:16" \
  --poll-seconds 10
```

## Generate a longer video by stitching segments

Veo commonly outputs ~8s clips per request. Use `--segments` to generate multiple clips and concatenate them with ffmpeg.

**Important:** This skill sends **one prompt per segment** (one Veo request per segment). Use `--base-style` to keep style consistent across segments.

```bash
uv run {baseDir}/scripts/generate_video.py \
  --prompt "Same scene, consistent style..." \
  --filename "out-24s.mp4" \
  --model "veo-3.1-generate-preview" \
  --aspect-ratio "9:16" \
  --segments 3 \
  --segment-style continuation
```

Options:
- `--base-style "..."`: prepended to every segment prompt (recommended).
- `--segment-prompt "..."` (repeatable): provide one prompt per segment (overrides `--prompt`).
- `--segment-style continuation` (default): appends continuity instructions per segment (only when using `--prompt`).
- `--segment-style same`: uses the exact same prompt for each segment (only when using `--prompt`).
- `--use-last-frame`: for segment >=2, extract previous segment last frame and pass it as `lastFrame` for continuity.
- `--emit-segment-media`: print `MEDIA:` for each segment as it finishes (useful for progress).
- `--keep-segments`: keep intermediate `*.segXX.mp4` files.
- `--reference-image path.jpg` (repeatable): guide generation with product/style references.

## Requirements

- `GEMINI_API_KEY` env var (or `--api-key`).
- `ffmpeg` on PATH when using `--segments > 1`.

## Troubleshooting

- 429/RESOURCE_EXHAUSTED: API key has no quota/billing for video.
- 503/UNAVAILABLE: model overloaded; retry later.

rpg-migration-analyzer

Included

Analyzes legacy RPG (Report Program Generator) programs from AS/400 and IBM i systems for migration to modern Java applications. Extracts business logic from RPG III/IV/ILE source code, identifies data structures (D-specs), file operations (F-specs), program dependencies (CALLB/CALLP), and converts RPG constructs to Java equivalents. Generates migration reports, complexity estimates, and Java implementation strategies with POJO classes, JPA entities, and service methods. Use when modernizing AS/400 or IBM i legacy systems, analyzing RPG source files (.rpg, .rpgle, .RPGLE), converting RPG to Java, mapping data specifications to Java classes, planning legacy system migration, or when user mentions RPG analysis, Report Program Generator, RPG III/IV/ILE, AS/400 modernization, IBM i migration, packed decimal conversion, or mainframe application rewrite.

brand-library-architect

Included

Build a complete brand library for a product — visual asset render pipeline, brand documentation set (BRAND, COPY, MANIFESTO, BIOS, FAQ, GLOSSARY, TONE, PRICING), open-source convention files (README, CONTRIBUTING, SECURITY, CODE_OF_CONDUCT), and a self-contained press kit. This skill should be used when the user asks to "build a brand library / brand kit / press kit / brand assets" for a product, "set up a brand library workflow," "create a positioning manifesto plus visual identity," or any combination of brand documentation + visual asset pipeline. Apply phase-by-phase or run end-to-end. Templates are product-agnostic and use {{TOKEN}} placeholders the skill prompts the user to fill.

writing-tech-post

Included

Authors engineering blog posts end-to-end: launch deep-dives, incident postmortems, architecture migrations, performance case studies, tutorials, AI/agent system writeups, security disclosures, and research-to-product translations. Picks the correct archetype, plans the abstraction ladder, enforces an evidence cadence (diagrams, benchmarks, profiles, traces, code, ablations), tunes voice against publisher house styles (Datadog, Vercel, GitHub, AWS, Meta, Cloudflare, Jane Street), and runs a pre-publish gate for narrative momentum and disclosure ethics. Use when drafting a new engineering post, restructuring a draft that feels flat, deciding which evidence form belongs where, validating that depth and product context are balanced, or preparing a postmortem, migration, or performance narrative for external publication. Do not use for API reference documentation, README authoring, marketing copy, release notes, generic SEO content, ghost-written executive thought leadership, or non-engineering long-form essays.
