Voice Validator Skill

Overview

This skill operates a rigorous critique-and-rewrite enforcement loop for voice fidelity. It scans content against voice-specific negative prompt checklists, documents violations with evidence, fixes them while preserving intent, and rescans to confirm the revision passes — up to 3 iterations maximum.

The workflow implements the Iterative Refinement pattern: scan → document violations → revise → rescan. This ensures voice violations are caught systematically and fixed methodically without over-engineering or changing meaning.

CRITICAL CONSTRAINT: Never revise content without first scanning against the full checklist. Every violation must cite a specific quote. After 3 failed iterations, output with flagged concerns rather than continuing indefinitely.

Instructions

Phase 1: IDENTIFY TARGET

Goal: Determine the voice, mode, and content to validate.

Step 1: Identify voice target

• Determine target voice from context or user instruction
• Identify mode if applicable — casual modes may have additional specific checks
• Reference the target voice's checklist (contact user if unclear)

Step 2: Load content

• Read the content to validate
• Note content length — longer content is more prone to drift

Gate: Voice target and mode identified. Content loaded. Proceed only when gate passes.

Phase 2: SCAN

Goal: Run full checklist against content and identify all violations with evidence.

Step 0: Run deterministic stylometry checks

When the target voice has a profile.json, run the stylometry script first. It emits structured findings (rule_id, span, severity) that anchor the scan in measured data:

python3 scripts/voice-stylometry.py check \
  --profile skills/voice-{name}/profile.json \
  --draft <content-file>

Deterministic checks it runs:

• Burstiness band (burstiness.band, warning): draft sentence-length variance must fall inside the author's measured band; uniform sentence length is an AI tell.
• Punctuation profile (punctuation.em_dash|semicolon|parenthetical, warning): em-dash, semicolon, and parenthetical rates classified never/rare/habitual; flags drafts whose class deviates from the author's.
• Corrective antithesis (ai_tell.corrective_antithesis, error): "not X, it's Y" constructions, inline and across sentence pairs.
• Temporal openers (ai_tell.temporal_opener, error): throat-clearing paragraph openers ("In today's...", "In an era...", "Now more than ever...").
• Uniform paragraph shapes (ai_tell.uniform_paragraphs, error): four or more consecutive paragraphs with identical sentence counts.
• Profile decay (profile.stale, advisory): profile older than its refresh_after_days window. Advisory only — it asks for a profile refresh and never blocks the draft. Exit code stays 0 when only advisory findings exist.

Exit code 1 means error/warning findings exist; carry each finding into the violation list below. Profiles without stylometry or decay fields skip those checks and remain valid.

Step 1: Run negative prompt checklist

Check all categories against the target voice's checklist. Standard categories include:

• Tone: Does the tone match the voice profile? (e.g., too polished, too corporate, missing warmth)
• Structure: Does the structure match? (e.g., front-loaded constraints, clean outlines, wrap-ups)
• Sentences: Do sentence patterns match? (e.g., dramatic short sentences, rhetorical flourishes, symmetrical structure)
• Language: Any banned words? (amazing, terrible, revolutionary, perfect, game-changing, transformative, incredible, outstanding, exceptional, groundbreaking), marketing/hype, inspirational, unnecessary superlatives
• Emotion: Does emotion handling match? (e.g., explicitly named emotions, venting/ranting, moralizing)
• Questions: Do question patterns match? (e.g., open-ended brainstorming, vague curiosity)
• Metaphors: Do metaphor patterns match? (e.g., journey/path, biological/growth, narrative/story)
• Narrative (500+ words only; full 13-check rubric in references/narrative-patterns.md):
  • Evidence speaks for itself, or narrator over-explains the point?
  • Emotional registers mixed (named feelings + behavioral cues + sensation)?
  • Secondary threads present that enrich the main argument?
  • Reader's experience acknowledged?
  • Temporal structure varied (callbacks, non-linear points)?
  • References specific (named people, works, sources)?
  • Room for uncertainty and loose ends, or subject has every answer?
  • Intensity varies (peaks and valleys), or flat throughout?
  • Event types diverse, or every paragraph does the same thing?
  • Ending carries forward motion, or defaults to tidy realization epilogue?

Step 2: Check pass conditions

Verify the content matches the target voice's positive identity markers. Common pass conditions include:

• Feels like the person actually wrote it
• Voice-specific patterns are present (thinking out loud, warmth, precision, etc.)
• Could NOT be posted on LinkedIn without edits (for casual voices) — this heuristic catches ~80% of voice violations
• Does NOT sound like AI wrote it
• Narrative structure shows variety — secondary threads, temporal variation, forward-motion ending
• Mode-specific patterns are present (casual modes: no preamble, no wrap-up; formal modes: structured flow)

Step 3: Document violations

For each violation, record:

1. Category (tone, structure, sentence, language, emotion, question, metaphor, narrative)
2. Quoted text from the content
3. Specific fix recommendation

Key constraint: Only scan at this stage; save revisions for the next phase. Subjective assessment without a checklist misses specific violations.

Gate: Full checklist scanned. All violations documented with evidence. Proceed only when gate passes.

Phase 3: REVISE

Goal: Fix all violations while preserving content intent and substance.

Step 1: Apply fixes

• Address each violation with the smallest change that resolves it
• Preserve the original meaning and information
• Maintain natural flow — fixes should not create new violations

Step 2: Verify no overcorrection

• Ensure revisions did not strip necessary content
• Confirm the substance and technical accuracy remain intact
• Keep the revision to voice-level changes only; leave paragraphs and arguments intact

Key constraint: Make the smallest change that resolves each violation. Preserve all meaning. Changing substance is scope creep.

Gate: All documented violations addressed. Intent preserved. Proceed only when gate passes.

Phase 4: VERIFY

Goal: Confirm revised content passes all checks.

Step 1: Rescan revised content

Run the full checklist from Phase 2 against the revised version.

Step 2: Evaluate result

• If PASS: Output final content with validation report
• If FAIL and iteration < 3: Return to Phase 3 with new violations
• If FAIL and iteration = 3: Output content with flagged remaining concerns

Key constraint: Always rescan. "Should be fine" is a rationalization. Fixes can introduce new violations.

Step 3: Output validation report

VOICE VALIDATION: [Voice Name] Mode [mode]
SCAN RESULT: [PASS/FAIL]
VIOLATIONS DETECTED: [N]
ITERATION: [1-3]

[If violations:]
1. [Category]: "[quoted violation]"
   Fix: [specific correction]

2. [Category]: "[quoted violation]"
   Fix: [specific correction]

REVISED OUTPUT:
[Corrected content]

RESCAN RESULT: [PASS/FAIL]

Gate: Content passes all checks, or maximum iterations reached with flagged concerns. Validation complete.

Examples

Example 1: Technical Voice Validation

User says: "Validate this draft is in the right voice"

Actions:

1. Identify target voice from context, determine mode from content style (IDENTIFY TARGET)
2. Run full 8-category checklist (Tone, Structure, Sentences, Language, Emotion, Questions, Metaphors, Narrative), find 2 violations (SCAN)
3. Fix "I'm excited to share" (named emotion) and "This changes everything" (dramatic short sentence) (REVISE)
4. Rescan revised content, confirm PASS (VERIFY)

Result: Clean content with validation report

Example 2: Community Voice Validation

User says: "Does this sound like the right voice?"

Actions:

1. Identify target voice from context (IDENTIFY TARGET)
2. Scan against voice checklist, find missing warmth and no sensory details (SCAN)
3. Add experiential language and warmth while preserving substance (REVISE)
4. Rescan, confirm warmth and sensory details present, PASS (VERIFY)

Result: Content matches voice profile

Error Handling

Error: "Voice Target Unclear"

Cause: Content doesn't specify which voice to validate against, or context is ambiguous

Solution:

1. Check conversation context for voice mentions
2. Look for voice-specific patterns to infer target
3. If still unclear, ask user to specify voice name and mode

Error: "Violations Persist After 3 Iterations"

Cause: Fundamental mismatch between content substance and voice requirements, or conflicting checklist items

Solution:

1. Output content with clearly flagged remaining violations
2. List specific checklist items that resist correction
3. Suggest the content may need to be regenerated from scratch with the correct voice skill

Error: "Revision Introduced New Violations"

Cause: Fixing one category created violations in another (e.g., removing dramatic sentences introduced polished phrasing)

Solution:

1. Address new violations in next iteration
2. If oscillating between two violation types, fix both simultaneously
3. Prioritize tone and language violations over structural ones
