dvcrn catime — AI-Generated Hourly Cat Images 🐱
One-liner: Fetch the latest (or any) AI-generated cat image and send it to the user with a caption and story.
Every hour, catime generates a unique cat artwork using Google Gemini. This skill allows an AI agent to retrieve cat images by number, date, or recency and send them directly to the user via the message tool.
Installation
pip install catime
After installation the catime CLI is available. Verify:
catime --help
Quick Start for AI Agents
Step 1 — Retrieve a cat image with catime
Run the CLI to get image metadata. The most common command:
catime latest
Exact output:
Cat # 241 2026-02-11 04:57 UTC model: gemini-3-pro-image-preview
URL: https://github.com/yazelin/catime/releases/download/cats/cat_2026-02-11_0457_UTC.webp
Idea: 一隻以精緻黑絲線繡成的貓咪，正專注地在微縮的金色與黑色奢華香氛實驗室中，嗅聞試香紙上的氣味，整個場景以刺繡的微縮立體模型形式呈現。
Prompt: An embroidered illustration of an elegant black cat, crafted from exquisite black silk threads with visible needlework, satin stitch, and French knots. The cat is presented as a handcrafted textile art miniature diorama...
Story: 在一個宛如織品藝術品的微縮香室裡，環形燈的光線均勻地灑落，凸顯出所有織品與布料的精緻質感。這隻優雅的黑貓，其絲線繡成的毛髮閃爍著低調的光澤，牠全神貫注地分辨著香氣，周圍是數個鑲有金色瓶蓋的繡花香水瓶。牠正試圖從層疊的香氣中，捕捉那一縷最為珍貴的靈感。
Step 2 — Parse the output and send the image to the user
Extract the URL from the line starting with URL:. Then use the message tool (or equivalent) to send the image along with a caption.
Example message tool payload (YAML):
action: send_message

Prompt: An embroidered illustration of an elegant black cat…
Story: 在一個宛如織品藝術品的微縮香室裡…
Parse guidance: The first line says Found N cat(s) for 'today':. Then each cat entry follows the same format as catime latest. To send the newest, pick the last entry.
catime <number>
Fetch a specific cat by its sequential number.
Input:
catime 42
Output:
Cat # 42 2026-01-31 23:24 UTC model: gemini-3-pro-image-preview
URL: https://github.com/yazelin/catime/releases/download/cats/cat_2026-01-31_2324_UTC.webp
Parse guidance: Same format. Short entries (like numbered lookups) may only show the header and URL lines without Idea/Prompt/Story.
catime --list
List all cats (number + URL, compact format).
Input:
catime --list
Output (first 10 lines):
Cat # 1 2026-01-30 05:46 UTC model: gemini-2.5-flash-image
URL: https://github.com/yazelin/ccat/releases/download/cats/cat_2026-01-30_0546_UTC.png
Cat # 2 2026-01-30 05:56 UTC model: gemini-3-pro-image-preview
URL: https://github.com/yazelin/catime/releases/download/cats/cat_2026-01-30_0556_UTC.webp
Cat # 3 2026-01-30 06:23 UTC model: gemini-3-pro-image-preview
URL: https://github.com/yazelin/catime/releases/download/cats/cat_2026-01-30_0623_UTC.webp
Cat # 4 2026-01-30 06:33 UTC model: gemini-3-pro-image-preview
URL: https://github.com/yazelin/catime/releases/download/cats/cat_2026-01-30_0633_UTC.webp
Cat # 5 2026-01-30 06:53 UTC model: gemini-2.5-flash-image (fallback from gemini-3-pro-image-preview, reason: timeout after 180.0s)
URL: https://github.com/yazelin/catime/releases/download/cats/cat_2026-01-30_0653_UTC.webp
Parse guidance: Each cat takes 2 lines. Odd lines are headers, even lines are URLs. Use --list | tail -2 to get the latest, or --list | wc -l to count cats (divide by 2).
catime <date>
Fetch cats from a specific date (YYYY-MM-DD format).
Input:
catime 2026-01-30
catime view
Opens the web gallery in the default browser. Not useful for agents — use latest or a number instead.
Agent Workflow: Send a Cat Image to User
Follow these steps exactly:
1. Decide which cat to fetch
| User request | Command to run |
|---|---|
| "Show me a cat" / "Send me a cat" | catime latest |
| "Show me today's cats" | catime today |
| "Show me cat number 42" | catime 42 |
| "Show me cats from Jan 30" | catime 2026-01-30 |
| "Show me a random cat" | catime $(shuf -i 1-241 -n 1) |
2. Run the command and capture stdout
output=$(catime latest 2>&1)
3. Parse the URL from stdout
Look for the line that starts with URL:. Extract everything after URL: .
Parsing rule (pseudocode):
for each line in output:
if line.strip().startswith("URL:"):
image_url = line.strip().removeprefix("URL:").strip()
break
Parsing rule (bash):
image_url=$(echo "$output" | grep ' URL: ' | head -1 | sed 's/.*URL: //')
4. Parse optional metadata
cat_number → from header line: regex `Cat #\s*(\d+)`
datetime → from header line: regex `(\d{4}-\d{2}-\d{2} \d{2}:\d{2} UTC)`
model → from header line: regex `model: (.+)$`
story → from line starting with ` Story: ` (everything after "Story: ")
prompt → from line starting with ` Prompt: ` (everything after "Prompt: ")
5. Send the image to the user
Use the message tool with the extracted URL and metadata:
action: send_message
media:
type: image
url: "<extracted image_url>"
caption: "🐱 Cat #<cat_number> — AI-generated cat of the hour!"
text: |
Here's your cat! Cat #<cat_number>, created at <datetime>.
Story: <story text>
metadata:
source: catime
cat_number: <cat_number>
model: <model>
generated_at: "<datetime>"
6. Fallback behavior
- If URL is missing: Tell the user the cat data was not available and suggest trying
catime latestor a different number. - If
catimeis not installed: Runpip install catimefirst, then retry. - If network error: The CLI fetches
catlist.jsonfrom GitHub. If offline, tell the user the cat gallery requires internet access. - If the user wants multiple cats: Use
catime todayand parse all entries (each entry separated by a blank line). Send the first or let the user choose.
Output Format Reference
Every catime command outputs cat entries in this format:
Cat # <NUMBER> <YYYY-MM-DD> <HH:MM> UTC model: <MODEL_NAME>
URL: <IMAGE_URL>
Idea: <SHORT_CONCEPT_TEXT>
Prompt: <FULL_GENERATION_PROMPT>
Story: <NARRATIVE_TEXT>
Field-by-field guide:
| Field | Line prefix | Always present? | Description |
|---|---|---|---|
| Number | Cat # (header) |
✅ Yes | Sequential cat ID (1, 2, 3, …) |
| Date/Time | header | ✅ Yes | UTC timestamp of generation |
| Model | model: (header) |
✅ Yes | AI model used (e.g. gemini-3-pro-image-preview) |
| URL | URL: |
✅ Yes | Direct link to the image file (.webp or .png) |
| Idea | Idea: |
Sometimes | Short concept (usually Chinese) |
| Prompt | Prompt: |
Sometimes | Full English prompt used for image generation |
| Story | Story: |
Sometimes | Narrative story for the cat (usually Chinese) |
Key notes for parsing:
- The
URLline is always present and is the critical field for sending images. Idea,Prompt, andStoryappear in detailed views (latest,today, specific number with detail) but may be absent in--listmode.- All URLs point to GitHub Releases — they are publicly accessible, no auth needed.
- Image formats are
.webp(most common) or.png(older cats).
Tips for AI Agents
- Always use
catime latestas the default when the user just wants "a cat." - The URL is on the line starting with
URL:— this is all you need to send an image. - Stories are in Chinese — you can translate them for English-speaking users or include them as-is for bilingual charm.
- Images are hosted on GitHub Releases — they load fast and don't require authentication.
- New cats appear every hour — if the user wants a fresh one,
latestalways works. - For random selection, pick a random number between 1 and the latest cat number.
--listis efficient for browsing — it only shows 2 lines per cat (header + URL).- Do not use
catime view— it opens a browser, which is not useful in agent/CLI context. - Include the story in your caption when available — it adds personality and delight.
- The Prompt field is useful if the user is curious about how the image was generated.
