Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00145 | $0.11769 |
| Opus 5.5 | $0.00058 | $0.04708 |
| Sonnet 5.5 | $0.00029 | $0.02354 |
| Haiku 4.5 | $0.00015 | $0.01177 |
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 2mo 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.
How it starts
The opening of the file, as written. The whole thing — 1,502 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/brand-voice — Brand Voice Engine
Generic copy converts worse than copy with a distinct voice. Not because the words are different — because the reader feels like they're hearing from a PERSON, not a marketing team.
This skill defines that voice. Either by extracting it from existing content, building it strategically from scratch, or auto-scraping a URL to analyze a brand's public presence.
Read ./brand/ per _system/brand-memory.md
Follow all output formatting rules from _system/output-format.md
Brand Memory Integration
On every invocation, check for existing brand context:
Reads (if they exist)
| File | What it provides | How it shapes output |
|---|---|---|
| ./brand/positioning.md | Market angles, differentiators | Informs voice positioning — a rebel brand sounds different from a trusted advisor |
| ./brand/audience.md | Buyer profiles, sophistication level | Jargon tolerance, formality level, cultural references |
Writes
| File | What it contains |
|---|---|
| ./brand/voice-profile.md | The complete voice profile (markdown + embedded JSON) |
Context Loading Behavior
- Check whether
./brand/exists. - If it exists, read
positioning.mdandaudience.mdif present. - If loaded, show the user what you found:
Brand context loaded: ├── Positioning ✓ "{primary angle summary}" └── Audience ✓ "{audience summary}" Using this to shape your voice profile. - If files are missing, proceed without them. Note at the end:
→ /positioning-angles would sharpen this profile → /audience-research would tune jargon level
Iteration Detection
Before starting any mode, check whether ./brand/voice-profile.md already
exists.
If voice-profile.md EXISTS → Update Mode
Do not start from scratch. Instead:
- Read the existing profile.
- Present a summary of the current voice:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ EXISTING VOICE PROFILE Last updated {date} by {skill} ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Voice summary: {current summary} Tone spectrum: ├── Formal ↔ Casual: {position} ├── Serious ↔ Playful: {position} ├── Reserved ↔ Bold: {position} ├── Simple ↔ Sophisticated: {position} └── Warm ↔ Direct: {position} ────────────────────────────────────────────── What would you like to change? ① Refine the tone (adjust the spectrum) ② Update vocabulary (add/remove words) ③ Add new content samples (re-extract) ④ Full rebuild (start from scratch) ⑤ Auto-scrape my site for fresh data
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.
