SYN-003
Context default
layer: clause
Prefer visible actor–action order
IF the reader must act or identify responsibility AND no stronger reason favors passive voice, THEN place the actor before the action ELSE retain.
Why the rule exists
Visible actors reduce ambiguity about responsibility.
Condition
The rule fires when this evaluates true. Paths marked below must be present in the fact base; the engine reports the rest rather than guessing them.
- ALL
- ANY
- context.purpose eq "instruct"
- content.responsibility_critical eq true
- clause.passive_justification eq false
- ANY
Facts this rule reads
| Path | Source |
|---|---|
context.purpose |
You supply it |
content.responsibility_critical |
You supply it |
clause.passive_justification |
You supply it |
Then
- convert — target
clause.voice, value"active"
Else
- retain — target
current_text, No triggering condition is present.

- Smallest sufficient intervention

Other syntax rules
- SYN-001 Complete clause for formal prose IF a unit is presented as a formal prose sentence AND lacks an independent clause, THEN attach it, complete it, or label it as a fragment ELSE retain. Hard constraint
- SYN-002 Separate fused independent clauses IF adjacent independent clauses have no valid boundary, THEN add a coordinator and punctuation, a semicolon, or a period ELSE retain. Hard constraint
- SYN-004 Use passive voice for a reason IF a clause is passive, THEN retain it only when the receiver is the topic, the actor is unknown or irrelevant, blame should be softened, or domain convention requires it ELSE convert to active. Context default
- SYN-005 Put conditions before instructions IF an instruction applies only under a condition, THEN state the condition before the imperative ELSE give the action directly. Context default
- SYN-006 One principal action per procedural step IF a step contains multiple independently verifiable actions, THEN split them into ordered steps ELSE retain a tightly coupled action. Context default
- SYN-007 Limit nested clauses for general audiences IF clause nesting exceeds two levels AND the audience is not expert-only, THEN split or promote a buried clause ELSE retain necessary complexity. Heuristic
- SYN-008 Given information before new information IF a sentence introduces new information before the anchor it depends on, THEN reorder from shared context to new contribution ELSE retain a deliberate surprise. Heuristic
- SYN-009 End-weight complex material IF a long complex phrase separates subject from verb OR delays the core relation, THEN move that weight later when meaning permits ELSE retain. Heuristic
