25# Summarize
26 
27Fast CLI to summarize URLs, local files, and YouTube links.
28 
29## When to use (trigger phrases)
30 
31Use this skill immediately when the user asks any of:
32 
33- “use summarize.sh”
34- “what’s this link/video about?”
35- “summarize this URL/article”
36- “transcribe this YouTube/video” (best-effort transcript extraction; no `yt-dlp` needed)
37 
38## Quick start
39 
40```bash
41summarize "https://example.com" --model google/gemini-3-flash-preview
42summarize "/path/to/file.pdf" --model google/gemini-3-flash-preview
43summarize "https://youtu.be/dQw4w9WgXcQ" --youtube auto
44```
45 
46## YouTube: summary vs transcript
47 
48Best-effort transcript (URLs only):
49 
50```bash
51summarize "https://youtu.be/dQw4w9WgXcQ" --youtube auto --extract-only
52```
53 
54If the user asked for a transcript but it’s huge, return a tight summary first, then ask which section/time range to expand.
55 
56## Model + keys
57 
58Set the API key for your chosen provider:
59 
60- OpenAI: `OPENAI_API_KEY`
61- Anthropic: `ANTHROPIC_API_KEY`
62- xAI: `XAI_API_KEY`
63- Google: `GEMINI_API_KEY` (aliases: `GOOGLE_GENERATIVE_AI_API_KEY`, `GOOGLE_API_KEY`)
64 
65Default model is `google/gemini-3-flash-preview` if none is set.
66 
67## Useful flags
68 
69- `--length short|medium|long|xl|xxl|<chars>`
70- `--max-output-tokens <count>`
71- `--extract-only` (URLs only)
72- `--json` (machine readable)
73- `--firecrawl auto|off|always` (fallback extraction)
74- `--youtube auto` (Apify fallback if `APIFY_API_TOKEN` set)
75 
76## Config
