Line Counter

text.count_lines

ProductionBounded custom (Class B)Deterministicstrictinstantv1.0.0

File inputNo network

Overview

You pass text (or a file_ref); we count lines using logical_lines (all lines separated by breaks) or non_empty_lines (only lines with non-whitespace), with explicit trailing-newline handling. We detect LF, CRLF, and CR. Do not use this for paragraph or word counting.

Line counting varies by trailing-newline and empty-line policy — we make both explicit.

Reliability

STRICT and deterministic for a given policy and count_trailing_empty_line setting. Input validation (not retryable): neither text nor file_ref; both provided; text too long; invalid policy.

Context footprint

Removes ambiguity about trailing newline semantics with one call. Accepts inline text up to 1,000,000 chars or file input via file_ref (up to 2 MB). Upload files via POST /v1/files/upload before passing file_ref. A successful call costs 1 execution credit.

When to use it

When you need a deterministic line count and must document the policy used.

When you need paragraph-level structure — use text.count_paragraphs.

Scope

Note

Counts lines using explicit policy (logical_lines or non_empty_lines), handles LF/CRLF/CR line endings.

How we handle your data

Sensitive input, safe output

What this means

This skill may receive sensitive content, but it does not target sensitive data and returns only a structured non-sensitive result.

Squillify guarantees

Runs inside Squillify
This skill runs inside Squillify.
Payloads are not sent to an external service by this skill.
Squillify does not permanently store submitted payloads.
Telemetry records metadata only, not submitted content.
Submitted payloads are not used for training.
Submitted payloads are not reviewed by humans.
This skill does not target sensitive data.
The response does not contain submitted content.

Your responsibility

Squillify does not determine whether submitted content is sensitive. Your application is responsible for deciding what data it is allowed to submit. Your application is responsible for securing the response.

Input schema

Field	Type	Required	Description
text	string	No	Bounded inline text source. Required unless file_ref is provided.
file_ref	string	No	Tenant-scoped opaque text-file reference. Omit it to use the required inline text; never send both.
policy	string	No	Line policy; omit it for logical_lines.
count_trailing_empty_line	boolean	No	Whether a final break opens a counted line; omit it for true.
return_segments	boolean	No	Reserved segment flag; omit it for false.

Output schema

Field	Type	Required	Description
skill	string	Yes	Producing skill key.
count	integer	Yes	Counted lines. This non-negative total is bounded by the documented input limit.
unit	string	Yes	Measurement unit for the returned line total.
policy	string	Yes	Applied line policy.
count_trailing_empty_line	boolean	Yes	Applied trailing-line setting.
line_breaks_detected	array	Yes	Bounded array containing from 0 through 3 items, where each item is one detected line-break style: LF, CRLF, or CR.
warnings	array	Yes	Bounded warning array containing from 0 through 4 items, where each item is one non-fatal advisory string.

Tip

Trailing newline creates an empty third line

Non-empty lines only
