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 | $0.00108 | $0.01974 |
| Opus 5 | $0.00054 | $0.00987 |
| Sonnet 5 | $0.00022 | $0.00395 |
| Haiku 4.5 | $0.00011 | $0.00197 |
Grade A, and why
blog-persona 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 9d 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.
This is a copy
88% identical to blog-persona — 29 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 210 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Blog Persona - Writing Voice Management
Create, store, and enforce writing personas based on the NNGroup 4-dimension tone framework and CMI Brand Voice Chart. Personas ensure consistent voice across all blog content produced by blog-write and blog-rewrite.
Commands
| Command | Purpose |
|---|---|
/blog persona create |
Interactive interview to build a new persona |
/blog persona list |
Show all saved personas |
/blog persona use <name> |
Set active persona for current session |
/blog persona show <name> |
Display full persona profile |
Create Workflow
Run the 6-step interactive interview. Ask each step, wait for response, then proceed.
Step 1: Brand Basics
Ask the user for:
- Brand name - company or personal brand
- Industry - primary sector (e.g., SaaS, health, finance, education)
- Target audience - who reads the blog (role, experience level, goals)
- One-sentence brand mission - what the brand helps people do
Step 2: Tone Dimensions (NNGroup Framework)
Present each dimension as a 0.0 to 1.0 slider. Explain both ends with examples.
| Dimension | 0.0 End | 1.0 End | Example at 0.0 | Example at 1.0 |
|---|---|---|---|---|
| funny_serious | Funny | Serious | "Let's be real, nobody reads Terms of Service" | "Understanding legal agreements protects your business" |
| formal_casual | Formal | Casual | "We are pleased to announce" | "Guess what - we shipped it!" |
| respectful_irreverent | Respectful | Irreverent | "We appreciate your patience" | "Yeah, that old way was broken" |
| enthusiastic_matter_of_fact | Enthusiastic | Matter-of-fact | "This changes everything!" | "Here are the results." |
Defaults if user is unsure: [0.6, 0.5, 0.3, 0.5] (slightly serious, balanced formality,
respectful, balanced enthusiasm).
Step 3: Writing Rules
Ask the user to pick a vocabulary tier first, then auto-suggest the matching readability band (user can override).
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.
