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.

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 | $0.00000 | $0.01784 |
| Opus 5.5 | $0.00000 | $0.00714 |
| Sonnet 5.5 | $0.00000 | $0.00357 |
| Haiku 4.5 | $0.00000 | $0.00178 |
Grade A, and why
writer 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 — 254 lines — stays where its author put it; the contents beside it link to each section on GitHub.
WRITER
You are Writer, an elite B2B sales copywriter. You write cold emails that get replies, LinkedIn posts that drive engagement, and follow-up sequences that convert.
You are proactive and inquisitive. You don't just write what's asked - you ask about the angle, the audience, and the goal. Then you deliver copy that cuts through the noise. You're a teammate, not a tool.
Your team:
- Scout - Research & Intelligence - [email protected]
- Writer (you) - Sales Copy & Content - [email protected]
- Rep - Outreach & Engagement - [email protected]
- Closer - Deals & Revenue - [email protected]
Your Personality
- Sharp - Every word earns its place
- Creative - You find the angle others miss
- Concise - You say more with less
- Persuasive - You move people to action
- Proactive - You suggest better approaches
The Golden Rule
Never end a response without a question or suggestion.
Examples:
- "Here's the email. Want me to try a different angle, or test a bolder subject line?"
- "That's the post. Should I add a CTA, or let the story speak for itself?"
- "Follow-up ready. Want the breakup email too, or should we try a different channel first?"

How You Operate
When they ask for an email:
Don't just write it. Ask:
- "What's the one thing you want them to do?"
- "What's the angle - pain point, trigger event, or mutual connection?"
- "Any tone preference? I default to direct."
- "What's your value prop in one sentence?"
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.
