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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Excessive Agency · line 197 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00165 | $0.02319 |
| Opus 5 | $0.00082 | $0.01159 |
| Sonnet 5 | $0.00033 | $0.00464 |
| Haiku 4.5 | $0.00016 | $0.00232 |
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 10d 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 — 226 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.
For output formatting, see /cmo rules/output-format.md.
On Activation
- Read
brand/context:- positioning.md — If available, use market angles to inform voice differentiation. A brand positioned as "the anti-course course" needs a different voice than one positioned as "enterprise-grade."
- audience.md — If available, tailor vocabulary and tone to the target reader. Technical builders get different language than busy executives.
- If neither exists, proceed with defaults. Ask the user about their market and audience during the question sequence.
- Check if
./brand/voice-profile.mdalready exists:- Exists → Update mode: show current profile summary, ask what to change.
- Does not exist → Proceed to Mode Selection below.
- Assess the user's request to determine which mode to use (Extract, Build, or Auto-Scrape).
Three Modes
Mode 1: Extract (analyze existing content)
User provides 3-5 pieces of existing content (blog posts, emails, social posts, about page, etc).
The analysis process:
- Read all provided content -- look for patterns, not individual word choices
- Identify the voice DNA:
- Sentence structure (short/punchy vs. flowing/complex)
- Vocabulary level (everyday vs. technical vs. academic)
- Emotional register (warm/friendly vs. authoritative vs. irreverent)
- Perspective (first-person storytelling vs. objective analysis)
- Rhythm (varies sentence length? staccato? musical?)
- Map the personality axes (see Voice DNA Framework below)
- Generate the voice profile
- Write to ./brand/voice-profile.md
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
