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 | $0.00071 | $0.00491 |
| Opus 5 | $0.00036 | $0.00246 |
| Sonnet 5 | $0.00014 | $0.00098 |
| Haiku 4.5 | $0.00007 | $0.00049 |
Grade A, and why
lifecycle-crm-email 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 7d 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 — 51 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Lifecycle CRM Email
Core Workflow
- Identify lifecycle stage, audience permission status, business goal, trigger, channel, message type, and compliance requirements.
- Segment by behavior, fit, lifecycle stage, product usage, source, intent, value, and consent.
- Map journey logic: entry criteria, message sequence, waits, branches, suppression, exits, and handoffs.
- Write emails around relevance, promise, proof, one primary CTA, and expected next step.
- Protect deliverability: permission, authentication, clean lists, engagement, suppression, frequency, and unsubscribe handling.
- Measure conversion, engagement, unsubscribe, complaint, bounce, downstream pipeline/revenue, and cohort retention.
Freshness Rule
Verify current official guidance for CAN-SPAM, CASL, GDPR/ePrivacy, SMS rules, platform acceptable-use policies, unsubscribe requirements, and email provider deliverability requirements when making compliance-sensitive recommendations. This skill is not legal advice.
Program Types
- Welcome and onboarding
- Lead nurture and MQL/SQL handoff
- Trial activation and product adoption
- Event/webinar follow-up
- Re-engagement and winback
- Renewal, expansion, and customer education
- Transactional or relationship messages with clear separation from promotional content
Compliance Guidance
Commercial email must use truthful sender/subject information, identify promotional content where required, include a valid physical address where applicable, provide an opt-out path, and honor opt-outs promptly. This is not legal advice; verify jurisdiction-specific requirements for GDPR, CASL, SMS, and industry rules when relevant.
Deliverable Shape
For lifecycle or email work, provide:
- Audience, lifecycle stage, and consent assumptions
- Trigger and segmentation logic
- Journey map or email sequence
- Message strategy and CTA
- Suppression, exit, and handoff rules
- Deliverability and compliance checks
- Measurement plan
References
- Read

What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

lifecycle-crm-email is a skill published in the GitHub repository jeremylongworth-source/AgentSkills (1 stars, last pushed 8d ago), licensed MIT. It adds 71 tokens to every session and 491 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings.
