Why should I use this skill instead of just asking an AI to count characters for me?

Unlike standard AI models that guess length based on tokens, this skill uses a precise Python-based script. This ensures you get a 100% accurate character count every time, avoiding the "hallucinations" common with basic LLM prompts.

Can I use this for platforms not listed in the description, like a personal blog or a niche marketplace?

The skill comes pre-configured for popular platforms like Etsy, Instagram, and X, but it also includes a custom override feature. You can manually set any character limit to match the requirements of niche marketplaces or personal blogs.

Does this skill support bulk processing for multiple product titles at once?

Yes, the skill is designed for efficiency and can process entire lists of titles or captions from a single .txt file. It will generate a status report for each item, flagging which ones are over the limit and which are safe to post.

How does the counter handle special elements like emojis or long URLs?

The skill calculates literal character counts including spaces; however, please note that it treats emojis and URLs as standard characters. If a specific platform uses unique "weighted" counting for links, you may want to set a slightly lower custom limit for safety.

How does the "Smart Trimming" feature decide which parts of my text to cut?

When an entry exceeds the limit, the skill suggests a shortened version that prioritizes keeping your most important keywords at the beginning. This ensures your value proposition remains visible even if the text is truncated by a platform's UI.

Check if this Etsy title is too long: "Handmade Vintage Blue Ceramic Vase for Home Decor - Large Floral Arrangement Pot"

Read your context and instructions
Compiled the title and caption

I have analyzed your Etsy title against the standard limit of 140 characters.

Text Length Analysis

Metric	Value	Status
Platform	Etsy Title	Reference: `limits.json`
Character Count	78	OK
Word Count	12	Valid
Limit	140	62 characters remaining
Hashtags	0	N/A

The title is well within the limits for Etsy. You have significant room to add more keywords if you want to optimize for search visibility.

Next steps
1.

Add keywords: Consider adding specific style tags like "Boho" or "Mid-Century" to utilize the remaining 62 characters.
2.

Validate tags: If you have a list of search tags for this item, I can check those against the 20-character Etsy tag limit.
3. Finalize: Once you reach the desired length, I can perform a final count to ensure no overages occur.

About this skill

Character limits and truncated titles kill conversion rates on marketplaces and social feeds. This skill automates the tedious task of measuring text length against platform-specific constraints, ensuring your copy fits before you hit publish.

What it does

Multi-platform counting measures characters, words, and hashtags against specific limits for sites like Etsy, Instagram, and X.
Bulk processing checks entire lists of titles or captions from a single text file to speed up batch uploads.
Limit overrides allows for custom character constraints when platforms update their rules or for niche sites.
Smart trimming suggests shortened versions of over-limit text while prioritizing the most important keywords at the start.
Status reporting flags text as OK, NEAR, or OVER to prioritize which items need immediate editing.

How it works

Define the target by specifying a platform or a custom character limit.
Input content via direct text strings or by pointing the skill to a .txt file for bulk analysis.
Analyze results to see the character count, word count, and exact space remaining or exceeded.
Refine and re-check by accepting automated trims or manually editing and running a final validation.

Frameworks & tools

This skill uses a Python-based execution environment and stores platform constraints in JSON format. It relies on standard string parsing for character and word counts.

Why this beats prompting it yourself

Standard LLMs often struggle with precise character counting due to tokenization and can hallucinate platform limits. This skill uses a dedicated Python script for exact math and references a specific JSON configuration for reliable constraints.

Use cases

Validating a batch of Etsy product titles to ensure they aren't cut off in search.
Checking if an Instagram caption stays within the character and hashtag limits.
Trimming long marketing hooks to fit within the strict constraints of X (Twitter).
Auditing a list of SEO meta descriptions for length compliance.

Known limitations

Character counts are literal and include spaces. Some platforms calculate emoji or URLs using special logic that this tool treats as standard characters.
