Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00052 | $0.00544 |
| Opus 5.5 | $0.00021 | $0.00218 |
| Sonnet 5.5 | $0.00010 | $0.00109 |
| Haiku 4.5 | $0.00005 | $0.00054 |
Grade A, and why
instagram-posting 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 1mo 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.

Instagram Posting Workflow
Overview
This skill guides a browser-capable agent through automating the process of uploading and publishing a post (video or image) to Instagram. It handles media upload, correct aspect ratio cropping, and adding tags/content.
Workflow Execution Steps
1. Identify Media Aspect Ratio
Before opening the browser, calculate the aspect ratio of the media to select the correct crop option on the upload screen.
- Use the bundled script:
python scripts/get_media_aspect_ratio.py <path_to_media_file> - The script will output the appropriate crop option:
1:1,4:5,16:9,9:16, orOriginal. - Note this exact crop option for use in Step 2.
2. Browser Automation: Uploading Media
Using your browser-automation capability (e.g., Playwright or Selenium), navigate to https://www.instagram.com/ and execute the following:
- Click 'Add' (Create Post): Locate and click the 'New Post' or 'Create' button (often a '+' icon) in the navigation menu.
- Upload Provided Video or Image:
- To bypass the OS file upload window, locate the hidden
<input type="file">element on the upload modal and set its value to the absolute path of the media file, or simulate a drag-and-drop of the file into the dropzone.
- To bypass the OS file upload window, locate the hidden
- Select Crop Option:
- Once the media is previewed, click the 'Crop' selector button (usually located at the bottom left of the preview).
- Click the option that corresponds to the ratio identified in Step 1 (e.g., Original, 1:1, 4:5, 16:9, or 9:16).
- Click Next: Proceed past any filter or edit screens by clicking 'Next' until reaching the final share screen.
3. Adding Provided Content and Tags
On the final "Create new post" screen:
- Locate the caption/description text area.
- Enter the provided content exactly as requested.
- Append the provided tags (hashtags) to the end of the content.
4. Publishing the Post
- Locate and click the 'Share' or 'Publish' button.
- Await confirmation that the post has been shared successfully before concluding the automation task.

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.
