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 | $0.00061 | $0.00645 |
| Opus 5.5 | $0.00024 | $0.00258 |
| Sonnet 5.5 | $0.00012 | $0.00129 |
| Haiku 4.5 | $0.00006 | $0.00064 |
Grade A, and why
email-writing-frameworks 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 1mo 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 — 124 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Email Writing Frameworks
1. Do the Maths Framework
Trigger + pitch + calculation + CTA
Structure:
Saw [trigger]. Companies like yours typically [problem costing X].
We helped [similar company] reduce this by [%].
Worth a quick call?
When to use: When you can quantify the problem or ROI
2. Short-Trigger Based Outreach
Rules:
- 3-4 sentences maximum
- Lead with observation, not pitch
- One clear CTA
Structure:
[Observation about their situation]
[Brief connection to pain point]
[Soft CTA]
When to use: Default framework for most cold outreach
3. Challenge of Similar Companies
Reference industry-specific pain and position as pattern you've seen.
Structure:
Companies doing [X revenue] in [industry] often struggle with [problem].
We've helped [similar companies] solve this by [solution].
Is this on your radar?
When to use: When targeting a specific vertical or company profile
4. Neutral Insight Framework
Share third-party resource (not your content) to build trust before pitching.
Structure:
Came across this [resource] that addresses [their problem].
Thought it might be useful given [observation about their situation].
[Optional soft pitch]
When to use: For warming up cold prospects, building trust first
5. Leader Responsibilities
Role-specific questions that prompt reflection.
Structure:
As [title], how are you currently handling [challenge]?
Most [titles] I talk to are dealing with [common problem].
Worth comparing notes?
When to use: When targeting specific roles with known pain points

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.
