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 | $0.00070 | $0.02890 |
| Opus 5.5 | $0.00028 | $0.01156 |
| Sonnet 5.5 | $0.00014 | $0.00578 |
| Haiku 4.5 | $0.00007 | $0.00289 |
Grade A, and why
email-composer 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.

Email Composer
Overview
Draft clear, effective professional emails with appropriate tone, structure, and purpose. This skill covers business correspondence, cold outreach, follow-ups, escalations, apologies, negotiations, internal communications, and stakeholder updates. Includes tone calibration, cultural sensitivity, and templates for common business scenarios.
Apply this skill whenever professional email communication needs to be drafted, refined, or strategized.
Multi-Phase Process
Phase 1: Context Assessment
- Identify the recipient(s) and their relationship to the sender
- Determine the email's primary purpose (inform, request, persuade, respond)
- Assess the appropriate formality level (see tone matrix)
- Consider cultural and organizational norms
- Identify any sensitive topics requiring careful framing
STOP — Do NOT begin drafting without knowing the recipient, purpose, and tone level.
Phase 2: Structure Planning
- Craft a clear, specific subject line
- Plan the opening (context-setting or relationship acknowledgment)
- Organize the body (one idea per paragraph, most important first)
- Define the call to action or next steps
- Choose an appropriate sign-off
STOP — Do NOT draft the full email without a subject line and clear CTA defined.
Phase 3: Drafting
- Write using the selected tone and formality level
- Keep paragraphs short (2-4 sentences maximum)
- Use bullet points for multiple items or action items
- Bold or highlight key dates, deadlines, or decisions
- Include all necessary context without over-explaining
STOP — Do NOT send without completing the review phase.
Phase 4: Review
- Read aloud for natural flow and tone
- Check that the subject line matches the content
- Verify all names, dates, and attachments are correct
- Ensure the CTA is clear and actionable
- Consider how the email reads if forwarded out of context
Email Type Decision Table
| Situation | Structure | Tone | Key Element |
|---|---|---|---|
| Status update to stakeholders | Inverted Pyramid | Professional | Bold status indicator, bullet points |
| Request for approval/decision | BLUF | Professional | Recommendation first, supporting data |
| Delivering bad news | Sandwich | Formal | Empathy, explanation, constructive close |
| Meeting request | Direct | Professional-Friendly | Agenda items, time options |
| Cold outreach | Personalized Hook | Professional | Specific observation about recipient |
| Follow-up (no response) | Gentle Reminder | Professional | Easy options, graceful out |
| Escalation | Structured Report | Formal | Impact, attempts made, specific ask |
| Apology | Acknowledgment + Action | Formal | Honest explanation, preventive measures |
| Internal team update | Quick Update | Friendly Professional | Brevity, action items highlighted |
| Negotiation | Collaborative | Professional | Shared interests, multiple options |
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.
