lifecycle

lifecycle is a skill for Claude Code, Codex from ali-demirbas/claude-lifecycle. It costs 117 tokens per session (1,823 once invoked), scanned A, original, MIT.

A router for lifecycle marketing work, which means planning and improving the stages of a customer's relationship with a business. It sends requests to the right specialised lifecycle tool, including work involving GA4, Google's web analytics service, and CRM campaigns.

In plain words
What is it for?
Use it to connect and check marketing data, map customer journeys, and route requests for lifecycle audits, copy, and marketing automation.
Why use it?
It helps choose the appropriate step when a marketing request could fit several related tools. This avoids using the wrong workflow or manually deciding which lifecycle task to run.

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

Token cost

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.

Security

Grade A, and why

lifecycle 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 4d 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.

Lifecycle — Router

You are the entry point of the claude-lifecycle engine. Parse the user's intent and route to the right sub-skill. Read ${CLAUDE_PLUGIN_ROOT}/CLAUDE.md rules before doing anything — they are binding.

When NOT to use this directly

  • The user already named an unambiguous subcommand or sub-skill ("run lifecycle-audit on this", "/lifecycle copy") — go straight to that skill; running it through the router's disambiguation step first is overhead with nothing to resolve.
  • Mid-pipeline, moving to the next stage the current skill already named (e.g. lifecycle-connect just finished and said "next: lifecycle-map") — continue directly; re-entering the router to re-derive a routing decision that was already made adds a step, not a check.
  • The request names something this plugin doesn't do at all (sending a live campaign, managing a CRM account) — don't force it into the closest-sounding row of the table below; say plainly what the plugin does and doesn't do (see Never do).

Routing table

User intent / subcommand Route to Notes
connect, "GA4 bağla", "verimi analiz et", "data quality" lifecycle-connect Always the first step for new projects
map, "event'leri haritala", "funnel çıkar" lifecycle-map Requires connect output (or runs it first)
journeys, "journey üret", "kampanya kur", "otomasyonlar" lifecycle-journeys The main deliverable
copy, "metin yaz", "email metni", "push metni" lifecycle-copy Can run standalone for an existing journey
audit, "journey'lerimi denetle" lifecycle-audit For existing/imported journey portfolios
results, "sonuçları gir", "performans verisi", "holdout sonuçları" lifecycle-results Closes the loop; needs a launched journey + performance data
export, "JSON ver", "dışa aktar" lifecycle-export Needs generated journeys
audience, "kitle sorgusu", "BigQuery SQL" lifecycle-audience Needs generated journeys + a data substrate (BigQuery export or CDP)
qa, "test payload", "tetikleyiciyi test et" lifecycle-qa Needs generated journeys
intake (rarely called directly) lifecycle-intake Usually triggered by other skills

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.
