Random Empty State Copy Packet Generator

Description

Compose caller-supplied empty, error or loading copy with fictional contexts and actions, retaining full text and a codepoint preview without editorial-quality claims.

An interface fixture makes content and state explicit so a consumer can test a rendering or interaction. Literal labels, modeled states, and calculated geometry remain separate from what a browser or assistive technology actually displays or announces.

Compose caller-supplied empty, error or loading copy with fictional contexts and actions, retaining full text and a codepoint preview without editorial-quality claims.

When to use this tool

Use this generator to create reproducible empty state copy packet cases from the supplied model or bank. Inspect the returned evidence before using cases in a test or exercise.

How to use the tool and how it works

Supply templates, contexts, actions, count, previewLimit in the field shapes below. Set seed when you need an explicit replay.
Run the tool and correct any input error. For generated controls, distinguish a successful fixture containing an invalid case from failure to generate the fixture.
Read packets. Use the conventions below. Keep answer-bearing fields separate when presenting an exercise.

Sample an empty-state template, context, and action independently, substitute the literal context token, and return the full text with a code-point-limited preview and the supplied state kind.^[1]

Input field	Meaning and units	Accepted input
templates	Templates	Required. Array of Object; no unknown keys.; minimum items 1; maximum items 32.
templates[].kind	Kind	Required. Text; one of "empty", "error", "loading".
templates[].text	Text	Required. Text; maximum UTF-16 length 256.
contexts	Contexts	Required. Array of Text; minimum UTF-16 length 1; maximum UTF-16 length 128.; minimum items 1; maximum items 32.
actions	Actions	Required. Array of Text; minimum UTF-16 length 1; maximum UTF-16 length 128.; minimum items 1; maximum items 32.
count	Count	Required. Safe integer; minimum 1; maximum 32.
previewLimit	Preview Limit	Required. Safe integer; minimum 0; maximum 256.
seed	Optional numeric seed; takes precedence over context randomness. Without either, use the fixed tool.io default seed.	Optional. Safe integer.

Output field	Interpretation	Returned shape
packets	Packets	Required. Array of Object; no unknown keys.; minimum items 1; maximum items 32.
packets[].kind	Kind	Required. Text; one of "empty", "error", "loading".
packets[].context	Context	Required. Text; minimum UTF-16 length 1; maximum UTF-16 length 128.
packets[].text	Text	Required. Text; maximum UTF-16 length 32768.
packets[].preview	Preview	Required. Text; maximum UTF-16 length 512.
packets[].action	Action	Required. Text; minimum UTF-16 length 1; maximum UTF-16 length 128.
randomness	Replay source and normalized 32-bit seed, or null seed for an advancing context source.	Required. Object; no unknown keys.
randomness.seed	Optional safe-integer replay seed; normalization and precedence are explained below.	Required. Safe integer. or Null.
randomness.source	Source	Required. Text; one of "context", "seed".

An explicit safe-integer seed takes precedence over injected context randomness and is normalized to an unsigned 32-bit integer. With no seed and no context source, replay uses the fixed tool.io default seed. A context source must return finite values from zero inclusive to one exclusive; its advancing state must be retained separately. randomness records the source and normalized seed, or null for context. These generators are not cryptographic random sources.

Limitations and assumptions

The action is not semantically matched to the selected state or context. This is copy-fixture assembly, not translation, content generation, or tested interface guidance; review tone and relevance before use.
A replay requires the same complete input and implementation. The stated sampling convention applies within its eligible space. A finite draw does not exhaust all possible outputs; repeats remain possible unless a distinct-selection rule is explicit.
The field tables state structural bounds; cross-field constraints and bounded search or output budgets also apply. Unknown keys are rejected where the object contract disallows them. Input errors are distinct from null fields and deliberate invalid controls in a successful output.

Alternative or Complementary methods

For a supplied example, inspect the returned construction or delegated check directly. To evaluate a consumer, also test cases chosen for its own boundaries; a generated finite corpus does not establish exhaustive coverage.
