funnel-analysis

funnel-analysis is a skill for Claude Code, Codex from event4u-app/agent-config. It costs 35 tokens per session (1,669 once invoked), scanned A, original, MIT.

A method for finding where people drop out of a product journey: visiting, signing up, becoming active, paying, and staying. This sequence is called a conversion funnel.

In plain words
What is it for?
Use it to compare signup sources, investigate a fall in paid conversions, and locate the stage where revenue is being lost between the first visit and long-term retention.
Why use it?
It shows which step is losing potential customers and helps separate a broad conversion problem from a problem affecting only certain groups or channels.

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 9d 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.

funnel-analysis

When to use

  • Conversion to paid dropped and nobody knows which step broke.
  • A new signup channel went live and you need to compare its funnel shape to the baseline.
  • A board ask: "where does the money leak between landing page and paying customer?"

Do NOT use for ranking features, valuation, or OKR decomposition (see Related Skills). Funnel analysis is a diagnostic, not a roadmap.

Cognition cluster

  • Mental model 16 — Leading vs. lagging indicators. Paid is lagging; activation is leading; signup is upstream of both. A funnel decision built on the lagging stage can only confirm the miss; the leading stage names the binding fix. See docs/contracts/mental-models.md § 16.
  • Mental model 13 — Occam's razor. When a stage drops, the simpler explanation usually wins: "acquisition mix shifted" beats "users no longer understand the product." Pick the simpler cause; it changes the move. See mental-models.md § 13.
  • Mental model 3 — Pareto (80/20). Drops are almost never uniform across segments; ~20 % of the segment × stage cells carry ~80 % of the loss. Segment before treating the average as actionable. See mental-models.md § 3.
  • Context-spine — product + customer-segment + funnel-stage. Read the product slot for what activation can actually mean in-product (the activation event must be shippable), the customer-segment slot for which segments' switch-events the funnel is built for, and the funnel-stage slot for the position of each stage relative to the buying journey. See context-spine.

Procedure

Step 0: Inspect

  1. Confirm the cognition cluster: this is conversion diagnosis, channel-agnostic. Paid social, organic, partner, and self-serve all share the same shape; only the inputs differ.
  2. Confirm event tracking exists for all 5 stages. If even one stage is inferred, the analysis is unreliable — flag and proceed under that caveat.

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 event4u-app/agent-config (10 stars, last pushed today), licensed MIT. It adds 35 tokens to every session and 1,669 once invoked, about $0.0002 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 2026-09-03.
