Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| get_growth_loopA | Get a newsletter growth loop with mechanism, when it wins, execution rules, and failure mode. Loops: lead_magnet, social_repurpose, cross_promo, referral, sponsorship_swap. Omit for all loops + selection logic. |
| get_welcome_sequenceB | The 6-email welcome sequence architecture: per-email job, timing, and subject shape (deliver → receipt → quick win → segment → soft offer → close), plus the one-job-per-email rules. |
| audit_subject_lineA | Audit an email subject line: mobile truncation length, all-caps, spam phrases, fake Re:/Fwd:, specificity. Returns PASS/NEEDS WORK. |
| interpret_list_metricA | Interpret a list metric against practitioner ranges: open_rate, click_rate, growth_rate, unsubscribe_rate, reply_rate. Returns healthy range, warning threshold, and the diagnostic. |
| get_monetization_readinessA | Given subscriber count (and optionally open/click rates as percents), returns readiness verdicts for the three monetization paths: own product, per-click sponsorships, flat-rate placements, with sequencing. Engagement monetizes; size impresses. |
| get_full_packA | The complete newsletter library in one payload: growth loops, welcome sequence, metric reads. |

Scored across 6 tools
Each tool addresses a distinct aspect of newsletter growth: the full library, specific growth loops, welcome sequence, subject line auditing, metric interpretation, and monetization readiness. Even though get_full_pack is an aggregate, its purpose as a one-shot summary is clearly separate from the detailed, focused tools.
Tool names follow a consistent verb_noun pattern: get_ for retrieval, audit_ for analysis, interpret_ for metric interpretation. All are lowercase with underscores, creating a predictable and coherent naming scheme.
With 6 tools, the server is well-scoped for a newsletter growth advisory domain. Each tool covers a major area without redundancy or bloat, making the surface easy to navigate.
The tool set covers the core lifecycle of newsletter growth strategy: acquisition (growth loops), onboarding (welcome sequence), content quality (subject line audit), measurement (metrics), and monetization. Minor gaps exist such as lack of tools for email body auditing or detailed revenue forecasting, but agents can still accomplish most workflows.
