Prairie Labs builds prompt-native software systems: plain text programs that language models can read, follow, and operate as working interfaces. Scissortail is the source language for these systems, giving structure to screens, rules, settings, memory, search, applications, and agent behavior inside ordinary .txt files. The goal is simple: make AI systems more inspectable, portable, and controllable by keeping the program surface readable to people while still being usable by models.

POLICY GeneralDisclaimer
Scissortail is a prompt-programming specification for writing long .txt systems.
It is not legal advice, financial advice, medical advice, security advice, or a
guarantee of model behavior.
A Scissortail file does not override the policies, permissions, capabilities, or
limitations of any platform, model, harness, operating system, or tool provider.
External actions require actual tool or harness confirmation. File writes,
imports, exports, emails, payments, searches, system changes, and other outside
state changes must not be claimed unless they are actually performed and visible
to the current environment.
Outputs generated through Scissortail systems should be inspected by a human
before operational, commercial, legal, safety-critical, or public use.

THIS DOCUMENT IS A SPECIFICATION.
THIS DOCUMENT DEFINES PROMPT-CODE STYLE, NOT EXTERNAL IMPLEMENTATION.
THIS DOCUMENT PRESERVES SOURCE STYLE AND REMOVES ADVANCED MATH / GATE MACHINERY.
════════════════════════════════════════════════════════════════════════════════
§0. ROOT CONTRACT
════════════════════════════════════════════════════════════════════════════════
SYSTEM Scissortail
Scissortail is a prompt-programming syntax for long .txt systems.
The .txt file is the program surface.
The model reads the file and behaves according to the declared system.
The syntax is made from title cards, sections, named blocks, fields, screens,
menus, policies, constraints, kernels, process steps, render surfaces, and exports.
This specification is not a compiler document.
This specification is not an implementation plan.
This specification is not a request for external machinery.
This specification describes how the source files speak to the model.
The core language principle:
NAME THE THING
DEFINE WHAT IT IS
DECLARE ITS FIELDS
DECLARE ITS RULES
DECLARE ITS PROCESS
DECLARE ITS DISPLAY
DECLARE ITS FAILURE CONDITIONS
END
END
INVARIANT Source_Style_Lock
The language MUST retain the source-code visual grammar.
Title cards, dividers, uppercase heads, indentation, and END closures are semantic.
Spacing is not ornamental when it defines a screen, menu, or command surface.
A Scissortail document MUST feel like a loaded system, not a chat instruction.
END
INVARIANT Prompt_Code_Only
The language MUST remain a .txt prompt-programming language.
The language MUST NOT require an external compiler, hidden host, or separate interpreter.
The model is the reader and behavioral executor of the text.
Every construct MUST be usable inside a plain text file.
END
INVARIANT Stripped_Advanced_Machinery
The advanced mathematical engine layer is outside this stripped surface.
The advanced symbolic gate family is outside this stripped surface.
Formal field math, curvature math, and protected internal gate symbols are not included.
Scissortail keeps the source style while removing machinery that requires external code.
END
INVARIANT No_Drift
Do not invent syntax outside the source family.
Do not replace block syntax with conventional programming syntax.
Do not reduce the language to prose paragraphs.
Do not convert the file into JSON, YAML, Python, or Markdown as the primary form.
Use source-style declarations first; nested object syntax is allowed where the source uses it.

The order is conventional, not mandatory unless a document declares it mandatory.
The source family prefers clear loading order because the model reads top to bottom.
Identity should appear before behavior.
Rules should appear before screens.
Structures should appear before they are referenced by screens or process steps.
Exports should appear after the object they export.
────────────────────────────────────────────────────────────────────────────────
1.2 MINIMAL DOCUMENT
────────────────────────────────────────────────────────────────────────────────
A minimal Scissortail program uses a title, a system block, one invariant, one screen, and END.

────────────────────────────────────────────────────────────────────────────────
1.4 DOCUMENT END
────────────────────────────────────────────────────────────────────────────────
The file may end with one of the following forms:
END

END SYSTEM
END DOCUMENT
The source family relies on local END blocks more than a global END marker.
A global marker is allowed when the document is intended for import or reuse.
════════════════════════════════════════════════════════════════════════════════
§2. VISUAL GRAMMAR
════════════════════════════════════════════════════════════════════════════════
────────────────────────────────────────────────────────────────────────────────
2.1 ASCII TITLE CARD
────────────────────────────────────────────────────────────────────────────────
The title card is a system boundary.
It is the first attention anchor in the file.
It should name the system, the role, the layer, and the scope.
FORM:
╔═══════════════════════════════════════════════════════════════════════════════╗
║ ║
║ SYSTEM NAME ║
║ ║
║ System Role / Subtitle ║
║ ║
╚═══════════════════════════════════════════════════════════════════════════════╝
RULES:
- Keep the title uppercase or spaced uppercase when authority is desired.
- Use one title card at the top of a system file.
- Use smaller section dividers after the title card.
- Do not use title-card styling for ordinary notes.
- The title card may include layer, vendor, or mode lines.
────────────────────────────────────────────────────────────────────────────────
2.2 HEAVY SECTION DIVIDERS
────────────────────────────────────────────────────────────────────────────────
Heavy dividers mark major sections.
FORM:
════════════════════════════════════════════════════════════════════════════════
§N. SECTION NAME
════════════════════════════════════════════════════════════════════════════════
ALTERNATE FORM:
════════════════════════════════════════════════════════════════════════════════
SECTION N: SECTION NAME
════════════════════════════════════════════════════════════════════════════════
────────────────────────────────────────────────────────────────────────────────
2.3 THIN SUBSECTION DIVIDERS
────────────────────────────────────────────────────────────────────────────────
Thin dividers mark local topics inside a section.
FORM:
────────────────────────────────────────────────────────────────────────────────
N.N SUBSECTION NAME
────────────────────────────────────────────────────────────────────────────────
────────────────────────────────────────────────────────────────────────────────
2.4 INDENTATION
────────────────────────────────────────────────────────────────────────────────
- Block bodies are indented for authority and grouping.
- Fields are aligned when readability matters.
- Nested lists use four spaces per level.
- Screens preserve literal spacing.
- Process steps place action names on one line and details beneath.
- Object blocks use key alignment rather than prose indentation.
────────────────────────────────────────────────────────────────────────────────
2.5 PROMPT LINES
────────────────────────────────────────────────────────────────────────────────
Prompt-facing command lines use the greater-than marker.
> Type your search into the command line
> Select 1, 2, or 3
> Press Enter to return
Reader-facing immediate directives use triple greater-than markers.
>>> THIS IS NOT SIMULATED
>>> DISPLAY ONLY THE TITLE SCREEN
>>> THE PROGRAM STARTS IMMEDIATELY AFTER READING THIS
════════════════════════════════════════════════════════════════════════════════
§3. DECLARATION FAMILY
════════════════════════════════════════════════════════════════════════════════
────────────────────────────────────────────────────────────────────────────────
3.1 DECLARATION HEADS
────────────────────────────────────────────────────────────────────────────────
SYSTEM declares the root identity and behavioral contract
CONST declares a named literal value
PRINCIPLE declares a philosophical rule or operating stance
AXIOM declares a non-negotiable law
INVARIANT declares a rule that remains true during operation
STRUCTURE declares a record shape
TYPE declares a type or semantic object
SCREEN declares a visible output surface
MENU declares a numbered navigation surface
PROGRAM declares a loadable prompt module
GAME declares a playable prompt module
POLICY declares behavioral governance
BOUNDARY declares a zone of restricted or forbidden content
CONSTRAINT declares a binding response rule
KERNEL declares a main loop or control routine
EXPORT declares importable or visible packaged objects
────────────────────────────────────────────────────────────────────────────────
3.2 STANDARD BLOCK FORM
────────────────────────────────────────────────────────────────────────────────
FORM:
DECLARATION_TYPE Name
prose definition
fields
rules
process
render surface
END
────────────────────────────────────────────────────────────────────────────────
3.3 OBJECT BLOCK FORM
────────────────────────────────────────────────────────────────────────────────
Object blocks are used when the source wants configuration density.
FORM:
DECLARATION_TYPE Name {
key: value
key: {
nested_key: nested_value
}
list:
- item
- item
}
────────────────────────────────────────────────────────────────────────────────
3.4 CLOSURE
────────────────────────────────────────────────────────────────────────────────
- A named block closes with END.
- An object block closes with }.
- Do not leave a declaration visually open.
- END is uppercase.
- Nested loops inside RENDER or PROCESS use END FOR or END WHILE.
- Local END markers should align with the declaration they close.
────────────────────────────────────────────────────────────────────────────────
3.5 PROSE AS BODY
────────────────────────────────────────────────────────────────────────────────
The source family does not treat prose as comments.
Prose is the behavioral payload.
A description line can carry as much force as a field line when it is inside a block.
VALID:
SYSTEM DeskAssistant
A calm assistant for office task triage.
The assistant routes requests by urgency and never invents completion.
END
The two prose lines are part of the system contract.
════════════════════════════════════════════════════════════════════════════════
§4. ACTIVATION DIRECTIVES
════════════════════════════════════════════════════════════════════════════════
────────────────────────────────────────────────────────────────────────────────
4.1 INSTALLATION FORM
────────────────────────────────────────────────────────────────────────────────
The source family often begins with a use or installation section.
FORM:
§0. INSTALLATION
1. Drop this file into LLM context.
2. System activates automatically.
3. Type: menu
4. Type: help
This form is declarative.
It tells the model how to treat the file after reading it.
────────────────────────────────────────────────────────────────────────────────
4.2 IMMEDIATE DIRECTIVE FORM
────────────────────────────────────────────────────────────────────────────────
>>> THIS IS NOT SIMULATED
>>> AFTER READING THIS FILE, DISPLAY ONLY THE TITLE SCREEN
>>> THE PROGRAM STARTS IMMEDIATELY AFTER READING THIS
>>> THIS IS NOT REAL CODE. IT IS A PROMPT.
>>> YOU ARE THE INTERFACE DESCRIBED BY THIS FILE.
Use this form sparingly.
It is high-authority and should appear before the root contract or inside §0.
────────────────────────────────────────────────────────────────────────────────
4.3 ACTIVATION RULES
────────────────────────────────────────────────────────────────────────────────
- Activation directives come before ordinary explanatory prose.
- They may instruct the model to render a title screen.
- They may declare that the program is active after reading.
- They may forbid simulated results if the program depends on live tools.
- They should not expose hidden machinery or speculate about implementation.
- They should be direct, uppercase, and unambiguous.

════════════════════════════════════════════════════════════════════════════════
§6. SYSTEM BLOCK
════════════════════════════════════════════════════════════════════════════════
────────────────────────────────────────────────────────────────────────────────
6.1 PURPOSE
────────────────────────────────────────────────────────────────────────────────
SYSTEM names the root identity of a prompt-program.
It declares what exists, what is visible, and what happens behind the scenes.
────────────────────────────────────────────────────────────────────────────────
6.2 FORM
────────────────────────────────────────────────────────────────────────────────
SYSTEM Name
A one-line identity statement.
A short role description.
A visible-surface list.
A behind-the-scenes behavior statement.
END
────────────────────────────────────────────────────────────────────────────────
6.3 CANONICAL EXAMPLE
────────────────────────────────────────────────────────────────────────────────
SYSTEM SourceFirstSearch
A source-first search interface.
The model searches, ranks, describes, and returns sources.
The model does not replace the result page with an answer layer.
The visible system contains only:
Title Screen
Result Screen
Preferences Page
Filters Page
History Page
All search execution, scoring, filtering, history writing, and state updates occur behind the scenes.
END
────────────────────────────────────────────────────────────────────────────────
6.4 SYSTEM RULES
────────────────────────────────────────────────────────────────────────────────
- SYSTEM appears near the top of the file.
- The first prose line should make the system legible in one sentence.
- Visible surfaces should be enumerated before hidden behavior.
- Do not put every rule inside SYSTEM; use INVARIANT and POLICY for rules.
- Do not introduce unreferenced roles in SYSTEM.
- If the program starts immediately, say so before or after SYSTEM.
════════════════════════════════════════════════════════════════════════════════
§7. PRINCIPLES, AXIOMS, AND INVARIANTS
════════════════════════════════════════════════════════════════════════════════
────────────────────────────────────────────────────────────────────────────────
7.1 PRINCIPLE FORM
────────────────────────────────────────────────────────────────────────────────
PRINCIPLE blocks express operating philosophy.
PRINCIPLE Stability_Over_Noise
Prefer stable output over decorative verbosity.
Under pressure, compress the response instead of expanding it.
When unsure, mark uncertainty plainly.
END
────────────────────────────────────────────────────────────────────────────────
7.2 AXIOM FORM
────────────────────────────────────────────────────────────────────────────────
AXIOM blocks declare non-negotiable laws.
AXIOM Text_Does_Not_Equal_Action {
rule:
"Saying an action happened does not make the action happen."
enforcement:
- Do not claim completion without evidence.
- Do not imply state change unless a state update is allowed.
- Rewrite false action claims into accurate status statements.
note:
"This protects the difference between language and action."
}
────────────────────────────────────────────────────────────────────────────────
7.3 INVARIANT FORM
────────────────────────────────────────────────────────────────────────────────
INVARIANT blocks declare a condition that must remain true.
INVARIANT Source_First_Display
Search results are displayed as sources.
Each source receives a direct link, rating bar, score, and source description.
The description helps the user decide whether to open the source.
The description must not become a full answer layer.
END
────────────────────────────────────────────────────────────────────────────────
7.4 FORCE LEVELS
────────────────────────────────────────────────────────────────────────────────
PRINCIPLE philosophy; shapes tone and judgment
AXIOM hard law; not negotiated
INVARIANT continuous condition; must remain true
POLICY domain rules; grouped governance
CONSTRAINT specific binding response behavior
BOUNDARY zone marker for restricted material
────────────────────────────────────────────────────────────────────────────────
7.5 RULE WORDS
────────────────────────────────────────────────────────────────────────────────
MUST
MUST NOT
REQUIRED
FORBIDDEN
ALLOWED
SHOULD
SHOULD NOT
MAY
DO NOT
NEVER
ALWAYS
Use high-force words only when behavior must be stable.
Too many high-force words can make the document noisy.

§13. KERNELS AND PROCESS
════════════════════════════════════════════════════════════════════════════════
────────────────────────────────────────────────────────────────────────────────
13.1 KERNEL PURPOSE
────────────────────────────────────────────────────────────────────────────────
KERNEL declares a main loop, initialization routine, command router, or page flow.
In Scissortail, a kernel is written as prompt-code process steps.
It remains plain text.
────────────────────────────────────────────────────────────────────────────────
13.2 KERNEL FORM
────────────────────────────────────────────────────────────────────────────────
KERNEL RunInterface
Main loop for the interface.
INPUT:
state : SystemState
OUTPUT:
screen : Screen
PROCESS:
1. Initialize visible state
state.current_screen ← TitleScreen
2. Render title screen
RENDER TitleScreen
3. Read command
command ← command line input
4. Route command
IF command = "P" THEN RENDER PreferencesPage
IF command = "H" THEN RENDER HistoryPage
IF command is text THEN handle as query or instruction
5. Continue
Return to command line after visible response
END
────────────────────────────────────────────────────────────────────────────────

────────────────────────────────────────────────────────────────────────────────
13.5 PROCESS RULES
────────────────────────────────────────────────────────────────────────────────
- Use numbered steps for long routines.
- Use phase labels when a routine has preparation, retrieval, rendering, and history steps.
- Use command routing in plain IF statements.
- Use RENDER when the next visible surface should be shown.
- Use WRITE only for declared logs, history, notes, or visible state.
- Do not claim external tool completion unless the tool result exists in the conversation.
- Do not use advanced mathematical notation in Scissortail kernels.
- Keep process readable to a human.
════════════════════════════════════════════════════════════════════════════════
§14. COMMAND SURFACE, STATE, AND HISTORY
════════════════════════════════════════════════════════════════════════════════
────────────────────────────────────────────────────────────────────────────────
14.1 COMMAND SURFACE FORM
────────────────────────────────────────────────────────────────────────────────
INVARIANT Command_Surface
The command line accepts:
P — open Preferences
F — open Filters
H — open History
text — execute text command
END
────────────────────────────────────────────────────────────────────────────────
14.2 COMMAND TABLE FORM
────────────────────────────────────────────────────────────────────────────────
COMMANDS:
P Preferences
F Filters
H History
menu Main menu
help Help screen
clear Return to title
text Default text action
────────────────────────────────────────────────────────────────────────────────
14.3 STATE DECLARATION FORM
────────────────────────────────────────────────────────────────────────────────
STRUCTURE SystemState
Active visible and remembered state.
current_screen : text — active screen name
preferences : Preferences — user-adjustable settings
filters : Filters — active filtering state
history : list<HistoryEntry> — visible history log
mode : text — current behavior mode
END
STRUCTURE Preferences
User-adjustable settings.
output_length : text — short | medium | long
display_mode : text — compact | normal | expanded
region : text — region hint for location-sensitive behavior
END
STRUCTURE Filters
User-adjustable inclusion and exclusion controls.
commercial_content : text — exclude | allow | only
minimum_rating : number [0,10] — lowest visible result score
custom_terms : list<text> — terms to include or exclude
END
────────────────────────────────────────────────────────────────────────────────
14.4 HISTORY RULES
────────────────────────────────────────────────────────────────────────────────
- History is declared if the system promises history.
- History entries should include timestamp, command, result summary, and visible screen.
- Do not claim a file was written unless the current environment actually created it.
- A History page is a browser for logs, not a guarantee of external persistence.
- If persistence is only in-chat, state that it is in-chat.
- If a program uses actual files, the file path or artifact should be visible.
════════════════════════════════════════════════════════════════════════════════
§15. CONTEXT RECORD SYNTAX
════════════════════════════════════════════════════════════════════════════════
────────────────────────────────────────────────────────────────────────────────
15.1 PURPOSE
────────────────────────────────────────────────────────────────────────────────
The source family includes context-layer records for simulations and domain systems.
Scissortail keeps the record syntax but removes advanced engine math.
Context records are plain structured prompt state.
────────────────────────────────────────────────────────────────────────────────
15.2 CONTEXT HEADER FORM
────────────────────────────────────────────────────────────────────────────────
CONTEXT FactoryOperations
name: "factory_ops"
description: "A factory operations simulation covering production, morale, maintenance, inventory, and finance."
END
────────────────────────────────────────────────────────────────────────────────
15.3 AXES AS RECORD LIST
────────────────────────────────────────────────────────────────────────────────
axes:
- id: "throughput"
name: "Throughput"
description: "Overall production output relative to target capacity."
min: 0
max: 100
initial: 60
high_semantics: "output is strong, lines moving efficiently"
low_semantics: "output is weak, bottlenecks forming, delays mounting"
critical_low: 20
- id: "morale"
name: "Worker Morale"
description: "Emotional and motivational condition of staff."
min: 0
max: 10
initial: 6
high_semantics: "motivated, cooperative, engaged workforce"
low_semantics: "fatigued, resistant, frustrated, burnout risk"
critical_low: 2
────────────────────────────────────────────────────────────────────────────────
15.4 TAGS AS RECORD LIST
────────────────────────────────────────────────────────────────────────────────
tag_definitions:
- id: "overtime_active"
name: "Overtime Active"
description: "Extra shifts or extended hours are running."
category: "labor"
- id: "breakdown"
name: "Machine Breakdown"
description: "A major piece of equipment has failed."
category: "maintenance"
────────────────────────────────────────────────────────────────────────────────
15.5 PHASES AS RECORD LIST
────────────────────────────────────────────────────────────────────────────────

description: "Production under pressure, disruptions active."
next_phases: ["normal_ops", "crisis"]
- id: "crisis"
name: "Crisis State"
description: "Multiple systems failing; urgent mitigation required."
next_phases: ["recovery"]
────────────────────────────────────────────────────────────────────────────────
15.6 ROOT FRAME AS TEXT BLOCK
────────────────────────────────────────────────────────────────────────────────
root_frame:
header: |
You are simulating the dynamic operations of a manufacturing plant.
Reflect state values in the narrative.
Treat tags as active conditions.
Show consequences that follow from the user's choices.
Keep all events believable within the declared context.
────────────────────────────────────────────────────────────────────────────────
15.7 CONTEXT RULES
────────────────────────────────────────────────────────────────────────────────
- Context records may use YAML-like lists when the source style uses them.
- Axis records describe value ranges and semantic meaning.
- Tag records describe discrete conditions.
- Phase records describe scenario modes and possible transitions.
- Root frame text anchors the domain behavior.
- Context records must remain readable as .txt.
- Do not add advanced field math to Scissortail context records.
════════════════════════════════════════════════════════════════════════════════
§16. EXPORTS
════════════════════════════════════════════════════════════════════════════════
────────────────────────────────────────────────────────────────────────────────
16.1 EXPORT PURPOSE
────────────────────────────────────────────────────────────────────────────────
EXPORT sections package systems, programs, profiles, policies, or attestations for import into another prompt file.
The source family uses both compact export lists and object exports.
────────────────────────────────────────────────────────────────────────────────
16.2 COMPACT EXPORT FORM
────────────────────────────────────────────────────────────────────────────────
SYSTEM_EXPORT:

}
────────────────────────────────────────────────────────────────────────────────
16.4 EXPORT RULES
────────────────────────────────────────────────────────────────────────────────
- Exports should appear after the objects they reference.
- Export names should be stable identifiers.
- An export should not include hidden secrets.
- Object exports may contain nested policy, boundary, and program records.
- Compact exports are better for module lists.
- Object exports are better for complete systems.

§29. SOURCE CONFORMANCE NOTES
════════════════════════════════════════════════════════════════════════════════
- The source family uses files as active system surfaces.
- A file may begin by instructing the model what to display after reading.
- A file may declare that it is not simulated when it needs real behavior.
- A file may define a title screen and expect the title screen to render immediately.
- A file may use uppercase contract language to create binding force.
- A file may use object blocks for dense configuration.
- A file may use plain record lists for context worlds.
- A file may use menus as deterministic navigation skeletons.
- A file may use screens as literal UI surfaces.
- A file may use kernels as prose control loops.
- A file may use constraints to prevent false action claims.
- A file may use export blocks to package systems or modules.
- A file should not require code outside the text to make its syntax meaningful.
- A file should not expose protected internal mechanisms.
- A file should not mix advanced math with this stripped surface layer.
────────────────────────────────────────────────────────────────────────────────
29.1 SOURCE FAMILY MOTIF
────────────────────────────────────────────────────────────────────────────────
The dominant motif is ceremonial clarity.
The document looks like a system manual and behaves like a system prompt.
This is why the visual frame matters.
This is why END matters.
This is why screens are literal.
This is why rules are named.
────────────────────────────────────────────────────────────────────────────────
29.2 PROMPT-CODE DENSITY
────────────────────────────────────────────────────────────────────────────────
- Use a title card to establish identity.
- Use sections to establish order.
- Use blocks to establish semantics.
- Use structures to establish state.
- Use screens to establish output.
- Use policies to establish boundaries.
- Use kernels to establish flow.
- Use exports to establish modularity.
════════════════════════════════════════════════════════════════════════════════
§30. ANTI-PATTERNS
════════════════════════════════════════════════════════════════════════════════
────────────────────────────────────────────────────────────────────────────────
30.1 Loose Prompt
────────────────────────────────────────────────────────────────────────────────
A paragraph asking the model to behave generally, without blocks or sections.
Remedy:
Convert to SYSTEM, INVARIANT, SCREEN, and KERNEL blocks.
────────────────────────────────────────────────────────────────────────────────
30.2 Unclosed Block
────────────────────────────────────────────────────────────────────────────────
A declaration that starts but never ends.
Remedy:
Add END or close the object brace.
────────────────────────────────────────────────────────────────────────────────
30.3 Invisible State
────────────────────────────────────────────────────────────────────────────────
A program that claims to track state but never declares the state shape.
Remedy:
Add STRUCTURE declarations for the state being referenced.
────────────────────────────────────────────────────────────────────────────────
30.4 Screen Drift
────────────────────────────────────────────────────────────────────────────────
A screen that adds explanation outside its RENDER block.
Remedy:
Move visible text into RENDER or remove it.
────────────────────────────────────────────────────────────────────────────────
30.5 Menu Drift
────────────────────────────────────────────────────────────────────────────────
A menu whose numbers change without reason.
Remedy:
Freeze numbering and route commands explicitly.
────────────────────────────────────────────────────────────────────────────────
30.6 Policy Fog
────────────────────────────────────────────────────────────────────────────────
A policy that names danger but gives no remedy.
Remedy:
Add CONSTRAINT blocks with remedies.
────────────────────────────────────────────────────────────────────────────────
30.7 False Persistence
────────────────────────────────────────────────────────────────────────────────
A history feature that claims external storage without an actual artifact.
Remedy:
State whether history is in-chat or artifact-backed.
────────────────────────────────────────────────────────────────────────────────
30.8 Action Theater
────────────────────────────────────────────────────────────────────────────────
Text that claims an action happened when only text was produced.
Remedy:
Rewrite as capability, plan, or visible completed artifact.
────────────────────────────────────────────────────────────────────────────────
30.9 Syntax Inflation
────────────────────────────────────────────────────────────────────────────────
Adding new heads when existing heads are sufficient.
Remedy:
Reuse the core block family.
────────────────────────────────────────────────────────────────────────────────
30.10 Math Leakage
────────────────────────────────────────────────────────────────────────────────
Bringing advanced formulas into the stripped prompt surface.
Remedy:
Remove advanced formulas from this stripped surface.

§32. CONVERSION GUIDE
════════════════════════════════════════════════════════════════════════════════
To convert an existing long prompt into Scissortail:
Opening instruction → move into ACTIVATION DIRECTIVES or SYSTEM
Identity paragraph → move into SYSTEM
Hard rule → move into AXIOM or INVARIANT
Soft preference → move into PRINCIPLE or Preferences STRUCTURE
Data shape → move into STRUCTURE or TYPE
Visible output → move into SCREEN RENDER
Menu choices → move into MENU
Command handling → move into KERNEL PROCESS
Safety boundary → move into BOUNDARY
Boundary response → move into CONSTRAINT
Module → move into PROGRAM or GAME
Reusable package → move into EXPORT

§42. FINAL LOCK
════════════════════════════════════════════════════════════════════════════════
SCISSORTAIL is now defined as a stripped .txt prompt-programming syntax.
It preserves the source family surface.
It keeps title cards, sections, constants, systems, principles, axioms, invariants,
structures, types, screens, menus, programs, games, policies, boundaries,
constraints, kernels, process steps, context records, render surfaces, and exports.
It excludes advanced math and protected gate machinery.
It does not require external code to be meaningful.
It is written to be read directly by a model as source text.
