description	Remove redundant content from documentation. Use when sections repeat information unnecessarily, type definitions appear multiple times, concepts are introduced more than once, or transition words clutter meaning. Reduces cognitive load through deduplication and strategic cross-referencing.

Reduce Redundancy from Documentation

Overview

Redundancy slows readers down by forcing them to process repeated information. Documentation should express each concept exactly once, use each phrase once, and remove unnecessary transition words that don't guide meaning. This skill helps identify and fix three types of redundancy: lexical (repeated words/phrases), structural (unnecessary transitions), and semantic (repeated concepts across sections).

Agent Workflow

Phase 1 — Scanning (no edits)

1. Read the full document
2. Use the Redundancy Detection Guide below to identify violations
3. Create one task per redundancy found:
   • "Remove redundancy – section:(Type:<lexical|structural|semantic>): "
4. List all tasks for user confirmation before editing

Phase 2 — Execution

1. For each task, apply the appropriate fix strategy (see Fixing Strategies table)
2. When removing a repeated definition, add a cross-reference (link) instead
3. Preserve all meaning—remove only unnecessary words
4. Mark each task completed as you finish

Phase 3 — Verification

After all tasks complete, compile the documentation:

sbt "docs/mdoc --in <file.md>"

Verify:

• No compilation errors
• Cross-references are valid (no broken links)
• Sections flow naturally after cuts
• Concept clarity is preserved

Redundancy Detection Guide

Type	How to Identify	Signal	Example
Lexical	Word appears 2+ times in same/adjacent sentences where only one is needed	Synonym appears nearby; removing word keeps meaning intact	"return back", "free gift", "unexpected surprise"
Lexical	Same phrase repeats in consecutive paragraphs	Copy-paste patterns; look for identical 3+ word phrases	Same code snippet introduced identically twice
Structural	Transition words that don't clarify sequence or relationship	Removing "furthermore", "also", "in particular" leaves meaning clear	"Furthermore, also," (both signal addition); "In this regard," when context is obvious
Structural	Signposting phrase that restates what was just said	Phrase like "as mentioned above" or "as we discussed"	"We showed earlier that X works. As mentioned above, X is useful."
Semantic	Type defined or explained in 2+ places	Same definition appears in different sections; same type signature shown multiple times	"Chunk is an immutable sequence" appears in Overview, Use Cases, and API section
Semantic	Example pattern repeats across sections	Same use-case explained with similar code/narrative structure	Multiple "hello world" examples in consecutive sections
Semantic	Motivation explained more than once	Concept justified in intro, then justified again later	"We need deduplication for performance" appears in both Overview and Benefits

Fixing Strategies

Apply the appropriate strategy based on redundancy type:

Redundancy	Strategy	Example
Lexical: synonym nearby	Remove the redundant word; keep one	Change "return back" → "return"
Lexical: phrase repeats	Extract to section intro or single location; use cross-reference	Define once at top; link from repeated locations
Structural: unnecessary transition	Delete transition word; verify sentence still flows	Delete "Furthermore,"; sentence should still read naturally
Structural: restated signposting	Remove phrase; rely on document flow	Delete "As mentioned above," — reader can infer from prior section
Semantic: repeated definition	Keep definition in primary location (earliest, or most prominent); replace repeats with [See X](#link)	First definition in Overview; later sections link to it
Semantic: repeated example	Choose the best/clearest example; remove others; add comparative note if examples show different patterns	Keep one realistic example; remove toy examples
Semantic: repeated motivation	Keep motivation in one place (usually intro); remove from later sections	Explain "why" once; don't repeat in each section

Common Mistakes

Mistake	Why It Fails	Fix
Over-aggressive cutting	Removing context leaves section unclear	Remove only redundancy; preserve concept explanations
Cutting example entirely	Readers need at least one concrete example	Keep best example; remove duplicates, not all examples
Removing type definition completely	Later sections may reference it without context	Always keep definition in first/primary location; link from others
Breaking cross-references	Links become invalid after moving content	Verify links after removing redundant sections
Removing transitions that clarify logic	Some transitions guide meaning ("first", "then", "because")	Only remove decorative transitions ("furthermore", "also")
Cutting without re-reading	Section becomes grammatically broken	Always read edited section aloud after cutting

Detection Hints

• Grep for repeated phrases: grep -n "<phrase>" <file.md> to find all occurrences
• Read for transitions: Scan for words: "also", "furthermore", "moreover", "in addition", "as mentioned", "as we discussed", "in this regard"
• Count type mentions: Each type should have at most one full definition; others should cross-reference
• Scan for patterns: Look for identical code structures or narrative patterns in consecutive examples

Integration

After completing this skill, the document is ready for:

• Stylistic review: Use /docs-writing-style to check prose rules
• Compliance check: Use /docs-check-compliance to audit against all rules
• Integration: Use /docs-integrate if adding the document to the site
