Classify Text Length

Overview

You pass text and a channel profile; we measure length in code points, grapheme clusters, and UTF-8 bytes, then classify it as too_short, optimal, acceptable, or too_long against versioned built-in limits (SMS, SEO/meta, social) or your customLimits. Do not treat built-in thresholds as live platform guarantees — pass customLimits when exact compliance matters.

Length limits are grapheme- and byte-sensitive — naive character counts mislead you.

Reliability

STRICT and deterministic. Classification: too_short (< minChars), optimal (≤ optimalMax), acceptable (≤ maxChars), too_long (> maxChars). Built-in profile thresholds are versioned (2026-05) and echoed in output.limits — editorial guidance, not a live mirror of any platform. Input validation (not retryable): missing text or profile; text too long; invalid profile or countMode; customLimits missing when profile=custom.

Context footprint

Returns classification, counts, applied limits, and overflow. A successful call costs 1 execution credit.

When to use it

When you check whether text fits a channel's length budget before publishing.

When you need exact live platform limits — pass customLimits instead.

Scope

Note

Classifies text length against channel or custom limits with grapheme awareness.

Input schema

Field	Type	Required	Description
text	string	Yes	Bounded text whose length is classified.
profile	string	Yes	Length-budget profile.
customLimits	object	No	Closed custom threshold object with minChars and maxChars properties; omit it to use the limits selected by a built-in profile.
countMode	string	No	Classification unit; omit it for graphemes.

Output schema

Field	Type	Required	Description
ok	boolean	Yes	Always true for a successful classification.
classification	string	Yes	Length-budget verdict.
counts	object	Yes	Closed measurement object with bounded codePoints, graphemes, and utf8Bytes properties.
limits	object	Yes	Closed resolved-limit object with profile, minChars, maxChars, countMode, and optional optimalMax and profileVersion properties.
overflowBy	integer	Yes	Units beyond the maximum. This non-negative total is bounded by the documented input limit.
