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 | $0.00052 | $0.01588 |
| Opus 5.5 | $0.00021 | $0.00635 |
| Sonnet 5.5 | $0.00010 | $0.00318 |
| Haiku 4.5 | $0.00005 | $0.00159 |
Grade A, and why
lifecycle-marketing 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 — 95 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Lifecycle Marketing
Reuse Growth Context
At the start, read .agents/growth-context.md when it exists. Reuse only product, customer, market, outcome, constraint, evidence, and routing fields whose scope, definition, source, and date remain compatible; state what is reused and surface conflicts or staleness before asking for decision-changing gaps. The file grants no system access or execution authority, and this Skill must not silently rewrite the primary diagnosis.
Plan lifecycle programs from bounded evidence and current channel permission. Public product information is enough to begin a useful blueprint. Private CRM, CDP, event, consent, account, and analytics artifacts are optional; record missing or declined private data as unavailable, never as failure, and do not request declined access again.
Read program-contract.md for intake, classification, draft gates, suppression, evidence, cadence, measurement, privacy, outputs, and handoffs. Read channel-gates.md whenever channel choice, fallback, market, language, locale, or localization affects the task. Read source-records.md before making a current platform, provider, regulatory, or capability claim.
Select One Mode
| Mode | Primary job |
|---|---|
welcome |
Establish the first expected relationship after a valid entry state |
activation |
Support a verified next-use milestone |
transactional |
Communicate a necessary service, account, or transaction state |
retention |
Support continued use or value realization |
win-back |
Invite an eligible former or inactive customer to return |
campaign |
Deliver a bounded non-sequence announcement or promotion |
Name one primary mode. Keep adjacent purposes separate rather than hiding promotion inside service content.
Freeze The Context
Record these as separate fields: market; language; locale; channel; mode; message classification; bounded audience and recipient eligibility; trigger/event semantics, source, and freshness; real sender; purpose; attributable claim evidence; channel-specific permission basis; platform and account-policy status; sender, account, or template registration status where applicable; current opt-out, do-not-contact, complaint, invalid-destination, consent-withdrawal, quiet-hour, frequency-cap, and suppression state; owner/legal/platform review state; cadence; collision policy; measurement capabilities; and source artifacts.
What ships with it
5 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-marketing is a skill published in the GitHub repository krillinai/growth-skills (43 stars, last pushed 2mo ago), licensed MIT. It adds 52 tokens to every session and 1,588 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
