Brand Context Sync

Synthesise the "Voice & Messaging" section for a client's CLAUDE.md from existing upstream skill outputs. This is a meta-skill — it reads files already in the project folder, it does not perform new research.

The purpose: every content skill auto-loads the client CLAUDE.md. By adding a standardised "Voice & Messaging" section, content skills get instant access to voice rules, messaging anchors, and competitive context without re-asking the user.

For full 3-phase process + DESIGN.md awareness rules → the premium reference.

Claude Code Triggers

Invoke this skill when:

• "sync brand context for [client]"
• "update voice section for [client]"
• "refresh client context"
• "add voice & messaging to CLAUDE.md"
• After completing /tov-guidelines for any client

Do NOT invoke when:

• User wants to run TOV analysis from scratch → use /tov-guidelines
• User wants full competitor research → use /competitor-research
• User wants to update project scope or file references in CLAUDE.md → edit manually

Input Requirements

Required

Input	Description	Source
Client project folder	Must be inside projects/consulting/{slug}/	User context or explicit path
Client CLAUDE.md	The file to update	projects/consulting/{slug}/CLAUDE.md

Optional (improve quality)

Input	How it helps
TOV guidelines output	Voice rules (Use/Avoid lists)
Brand guidelines output	Visual identity, vocabulary
Competitor research aggregate	Competitive quick-ref
ICP research output	ICP description, key people
Product messaging output	Messaging anchors (value prop, differentiators, CTA)
Expert POV output	Author voice and positioning

Validation checklist

Before proceeding, verify:

• Client CLAUDE.md exists and is readable
• At least one upstream file exists (brand/, competitors/, icp/, messaging/)
• Template file exists at VOICE-MESSAGING-TEMPLATE.md

If no upstream files exist: tell the user "No brand files found. Run /tov-guidelines first to generate source material."

Process at a glance

Phase	Purpose	Output
1. Locate	Scan project folder, determine CREATE vs UPDATE	File inventory + mode
2. Extract	Pull voice rules, vocabulary, messaging anchors, competitive quick-ref, key people	Section content (or MISSING markers)
3. Write	Format via template, insert/replace in client CLAUDE.md, verify	Updated CLAUDE.md

For full per-phase steps, MISSING-marker conventions, and DESIGN.md awareness → the premium reference.

Anti-Hallucination Guardrails

1. Verbatim voice rules. Copy Use/Avoid rules exactly from TOV. Don't paraphrase, generalise, or add rules not in source.
2. No invented messaging. If positioning/messaging output doesn't exist, mark as MISSING. Don't invent value props or differentiators.
3. No invented competitors. Only include competitors from competitor-research files. Don't add from general knowledge.
4. Source tracing. Every section must reference its source file.
5. Mark unknowns explicitly. Use [MISSING — run /[skill-name] first] for any section that can't be populated.

Quality Checklist (pre-delivery)

Content quality

• Voice rules are verbatim from source (not paraphrased)
• Max 12 Use + 12 Avoid rules (not more)
• Messaging anchors traced to positioning/messaging output
• Competitive quick-ref matches aggregate analysis
• MISSING sections clearly marked with the skill to run

Format quality

• Section header is exactly ## Voice & Messaging (auto-loaded by content skills)
• Subsection headers match template (Identity, Voice rules, Vocabulary, etc.)
• Arrows (→) used for differentiator lists
• Source file paths are relative to project root

Completeness

• All 7 subsections present (even if some are MISSING)
• Sources subsection lists all files that were read
• No other CLAUDE.md sections modified
