Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00046 | $0.01903 |
| Opus 5 | $0.00023 | $0.00951 |
| Sonnet 5 | $0.00009 | $0.00381 |
| Haiku 4.5 | $0.00005 | $0.00190 |
Grade A, and why
brand-voice 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 4d 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 Voice Skill
Frameworks for documenting, applying, and enforcing brand voice and style guidelines across marketing content.
Brand Voice Documentation Framework
A complete brand voice document should cover these areas. Use this framework to help users define their brand voice or to understand an existing brand voice configuration.
1. Brand Personality
Define the brand as if it were a person. What are its defining traits?
Example: "If our brand were a person, they would be a knowledgeable colleague who explains complex things simply, celebrates your wins genuinely, and never talks down to you."
2. Voice Attributes
Select 3-5 attributes that define how the brand communicates. Each attribute should be defined with:
- What it means in practice
- What it does NOT mean (to prevent misinterpretation)
- An example demonstrating the attribute
3. Audience Awareness
- Who the brand is speaking to (primary and secondary audiences)
- What the audience cares about
- What level of expertise the audience has
- How the audience expects to be addressed
4. Core Messaging Pillars
- 3-5 key themes the brand consistently communicates
- The hierarchy of these messages (which comes first)
- How each pillar connects to audience needs
5. Tone Spectrum
How the voice adapts across contexts while remaining recognizably the same brand.
6. Style Rules
Specific grammar, formatting, and language rules. See the Style Guide Enforcement section below.
7. Terminology
Preferred and avoided terms. See the Terminology Management section below.
Voice Attributes
Common Voice Attribute Pairs
When defining brand voice, it helps to position attributes on a spectrum. Here are common attribute spectrums:
| Spectrum | One End | Other End |
|---|---|---|
| Formality | Formal, institutional | Casual, conversational |
| Authority | Expert, authoritative | Peer-level, collaborative |
| Emotion | Warm, empathetic | Direct, matter-of-fact |
| Complexity | Technical, precise | Simple, accessible |
| Energy | Bold, energetic | Calm, measured |
| Humor | Playful, witty | Serious, earnest |
| Innovation | Cutting-edge, forward-looking | Established, proven |
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.

brand-voice is a skill published in the GitHub repository fergupa/claude_plugins (2 stars, last pushed 7mo ago), licensed Apache-2.0. It adds 46 tokens to every session and 1,903 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
