Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

cf-style-guide scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Brand Style Guide Importer

Import brand voice profiles from existing style guide documents, URLs, or manual input. Extracts tone, formality, personality traits, writing style, approved/banned terminology, and compliance guardrails into a structured brand profile JSON that the ContentForge pipeline uses for every piece of content it produces.

When to Use

Use /contentforge:cf-style-guide when:

  • You're onboarding a new brand and have an existing style guide document (.docx, .pdf) or URL
  • You need to update an existing brand profile with revised guidelines
  • You want to extract terminology and guardrails from compliance documents
  • You're setting up ContentForge for a regulated industry (Pharma, BFSI, Healthcare, Legal) where guardrails are critical
  • You want to validate that an existing brand profile matches current guidelines
  • A client provided a style guide URL (Notion page, Google Doc, website page) and you need to import it

For creating a brand profile from scratch (no existing style guide), use /contentforge:brand-setup with interactive mode. For using an existing brand profile, just reference it by name in /contentforge:create-content --brand=BrandName.

What This Command Does

  1. Load Style Guide — Fetch style guide from URL (via WebFetch), parse .docx/.pdf document, or accept manual input
  2. Extract Voice Characteristics — Identify tone (authoritative, conversational, technical, witty), formality level (1-5), personality traits, and writing style patterns
  3. Identify Terminology — Parse approved terms, banned/prohibited terms, industry-specific jargon, preferred spellings, and acronym definitions
  4. Parse Compliance Requirements — Extract guardrails, required disclaimers, prohibited claims, regulatory requirements, and sensitivity guidelines
  5. Capture Author Profiles (E-E-A-T) — If the style guide names authors/spokespeople (About/Team sections, byline conventions), extract name, title, credentials, bio, and profile URLs into author_profiles; otherwise prompt for at least one default author (or an explicit "authorless" choice, recorded with its SEO/AEO trade-off). Only user-confirmed facts — never invent credentials
  6. Configure the AI-Assistance Disclosure — Write the ai_disclosure block: {"mode": "claude-surfaces", "text": null, "author": null} by default. Explain the three modes plainly: claude-surfaces (default — the disclosure attaches when the pipeline runs on a Claude surface, or when the surface is uncertain; it is skipped only when a non-Claude harness is affirmatively detected), always (attach on every surface — the safest posture for brands with their own AI-transparency obligations), off (never attach; the brand owns that choice and its compliance implications). The author field is OPTIONAL and may stay null — the default wording ("reviewed by our editorial team") needs no name; when the brand does name someone, that name also feeds the E-E-A-T byline. Custom text replaces the default verbatim — note that the default is deliberately vendor-neutral and claims only the review the pipeline performs; a brand adding stronger claims owns them
  7. Generate Brand Profile JSON — Create or update a structured JSON profile following the brand-registry-template.json schema
  8. Save and Validate — Save profile to Google Drive (via MCP) or local cache using the brand-cache-manager pattern, and validate the profile works with the ContentForge pipeline
  9. Configure Tracking Backend — Choose where ContentForge tracks quality scores and delivers output files: Google Sheets + Drive, Airtable, or local filesystem

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
