funnel-analysis

funnel-analysis is a skill for Claude Code, Codex from krillinai/growth-skills. It costs 55 tokens per session (1,647 once invoked), scanned A, original, MIT.

A framework for analyzing funnels, meaning the observable steps customers or users pass through toward a goal, such as buying or adopting a product.

In plain words
What is it for?
Use it to define funnel states, calculate conversion and drop-off, compare cohorts or segments, diagnose constraints, and plan measurement or improvements.
Why use it?
It helps teams calculate where people drop out without changing the definitions or denominators, then separate observed losses from possible causes.

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

funnel-analysis 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 11d 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 — 83 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Funnel Analysis

Define how eligible customers move through observable value states, calculate loss without changing denominators, identify the most decision-relevant constraint, and design the next evidence or intervention. Work from supplied data or attributable public context. Private analytics, warehouse, CRM, product, billing, support, or research data is optional; mark missing or declined inputs unavailable, never fabricate funnel counts, rates, causes, or results.

Read funnel-contract.md for state definitions, evidence rules, metric contracts, identity, privacy, and reconciliation requirements. Read analysis-methods.md before calculating conversion, loss, time, cohort maturity, segment effects, or uncertainty. Read diagnosis-and-design.md before naming a constraint or proposing changes. Use playbook-sources.md to cite the pinned Growth Playbook basis.

Select One Mode

Mode Use
analysis Define or calculate a funnel or state model, reconcile counts, and compare mature cohorts or decision-relevant segments
diagnosis Separate an observed drop-off from candidate demand, qualification, value, friction, capacity, trust, retention, economics, or measurement mechanisms
design Design a funnel or state model, instrumentation contract, intervention portfolio, or validation plan for a supported constraint

Name one primary mode. A request may include secondary work, but keep observed calculations, causal hypotheses, and proposed interventions visibly separate.

Freeze The Funnel Contract

Record the decision and owner; final customer and business outcome; entity and level; canonical eligible starting population; ordered states or permitted state transitions; entry and success events for every state; numerator and denominator; observation and maturation windows; identity and deduplication; re-entry, skipping, reversal, and repeat rules; exclusions; timezone; market, language, locale, product surface, source, and segment boundaries; data version and capture date; guardrails; and known limitations.

Changes

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.

funnel-analysis is a skill published in the GitHub repository krillinai/growth-skills (43 stars, last pushed 15d ago), licensed MIT. It adds 55 tokens to every session and 1,647 once invoked, about $0.0003 per session on Opus 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.
