Short answer

How do I make sure my AI drafts don't exceed character limits?

Your agent uses the validate_context_integrity tool to scan drafts for exact character and word counts. This prevents API errors and ensures your content fits specific UI constraints. You'll see exactly where your text fails or passes these checks.

The outcomes of a length check.

Where your results land.

The AI processes your text and categorizes the result based on your constraints.

PASS

Valid text length

The AI confirms the draft stays within your specified bounds. You get a clean confirmation that the text is ready to use.

FAIL

Constraint violation

The AI identifies exactly how many characters or words you are over or under. You get a clear report of the discrepancy.

REVISE

Human review needed

When a draft is too close to the limit, the AI flags it for you. You decide if the content needs trimming or padding.

ERROR

Platform mismatch

The AI detects if the text will trigger a hard error in your target application. You get a warning to fix the length before attempting to post.

The workflow

What your AI does when the text arrives.

The AI acts as a gatekeeper for your content length.

  1. Scan draft

    The AI reads your provided text and calculates the raw character and word counts.

    validate_context_integrity

  2. Compare limits

    The agent compares those counts against the specific constraints you provided in the prompt.

    validate_context_integrity

  3. Identify gaps

    It pinpoints exactly how much text needs to be added or removed to meet the target.

  4. Report status

    The AI delivers a final verdict on whether the text is safe to send to your destination.

FAQ

How the length validation behaves

  • 01

    Can the AI rewrite the text to fit the limit?

    No. This tool only validates the length. You must ask your agent to rewrite the text in a separate instruction.

  • 02

    Does it count spaces as characters?

    Yes. The validation includes all characters, including spaces and punctuation, to ensure platform accuracy.

  • 03

    Can it automatically post to my social media?

    No. The AI only checks the text. You remain in control of the actual posting process.

  • 04

    Will it change my formatting?

    No. The tool reads your text to check length but does not modify your original content.

  • 05

    Can I set different limits for different platforms?

    Yes. You simply tell the agent what the specific character or word limit is for each check.
