Tools

developmental_edit

Run a high-level developmental edit on a chapter or scene. Analyzes and scores:

• Structure — scene flow, transitions, narrative arc position
• Character — dialogue balance, show-vs-tell ratio, emotional depth
• Pacing — sentence rhythm, chapter length, tension appropriateness
• Theme — vocabulary diversity, genre-specific thematic guidance
• Dialogue — tag usage, adverb-tag combinations, voice differentiation

Returns priority revisions ranked by severity.

analyze_pacing

Map the tension curve of a chapter segment by segment. Detects:

• Slow openings that lose readers
• Saggy midpoints where engagement drops
• Relentless intensity without breathing room
• Weak chapter endings that don't pull forward

Each segment is scored 1-10 for tension with dominant mode (action, dialogue, introspection, narration).

check_consistency

Detect inconsistencies across a manuscript passage:

• Pronoun ambiguity — multiple characters of same gender with unclear "he"/"she"
• Tense shifts — mixed past/present tense usage
• Word repetition — overused words that flatten prose
• Character tracking — mention counts and presence mapping
• Timeline markers — extracted time references for continuity checking

analyze_character

Deep analysis of a specific character within a passage:

• Arc type classification (transformation, steadfast, flat, mirror, corruption)
• Growth stage detection (rising-conflict, dark-moment, transformation, resolution)
• Voice markers from dialogue patterns
• Relationship map with other characters
• Development indicators and recommendations

line_edit

Prose-level analysis with quantified metrics:

• Average sentence length and variety score
• Passive voice percentage
• Adverb density per 1,000 words
• Readability grade (Flesch-Kincaid)
• Show-vs-tell ratio
• Sentence opener repetition detection

Returns specific examples and fix recommendations for each issue.
