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 | $0.00090 | $0.01340 |
| Opus 5 | $0.00045 | $0.00670 |
| Sonnet 5 | $0.00018 | $0.00268 |
| Haiku 4.5 | $0.00009 | $0.00134 |
Grade A, and why
founder-brand-onboarding 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 3d 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 — 203 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Founder-Brand Onboarding — first-run setup
The most important setup in this pack. The point of founder-brand content is that it sounds like YOU. Without SOUL.md, the skill produces LinkedIn-influencer-voice slop.
Activation
Loaded automatically by founder-brand on missing brand-config.json
or SOUL.md.
Also user-invocable: "Set up founder-brand onboarding", "Configure voice".
Workflow
Step 1 — Voice in 3 sentences
Describe how you actually write — in 3 sentences. Not "professional yet
approachable." Specific.
Examples of useful answers:
"I write declarative, with one claim per sentence."
"I lead with the receipt before the explanation."
"I don't soften with hedges — I either claim it or cut it."
Don't generalize. Tell me what's true about YOUR writing.
Save to SOUL.md (top section).
Step 2 — Phrases I use a lot (5-10)
Pull up your last 10 emails / posts / messages. What phrases show up
repeatedly? These are your voice fingerprints.
Examples (not yours — yours will differ):
"The lever is..."
"Specifically:"
"Here's the receipt:"
"What actually moved the number..."
5-10 phrases. These show up naturally in every output.
Save to SOUL.md.
Step 3 — Phrases I refuse (5-10)
What phrases would you NEVER write? Be specific. These get banned in
addition to the framework's banned-patterns list.
Common refuses:
"Synergy"
"Leverage" (as verb)
"Circle back"
"Delve into"
"Game-changing"
YOUR refuses might include things others use freely. Capture them.
Save to SOUL.md.
Step 4 — Voice settings
Pick your settings:
Formality: Casual / Professional / Direct
Sentence length: Short (≤15w) / Medium / Mixed
Confidence: High (outright) / Hedged / Calibrated
Humor: Dry / Never / Often
Profanity: Never / Sparingly / Often
First-person: I / We / Both
Emoji: Never / Sparingly (≤1/post) / Often
Save to SOUL.md.
Step 5 — Stories reservoir (3-5)
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.
