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.

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 | $0.00098 | $0.00828 |
| Opus 5 | $0.00049 | $0.00414 |
| Sonnet 5 | $0.00020 | $0.00166 |
| Haiku 4.5 | $0.00010 | $0.00083 |
Grade A, and why
funnel-decomposition-analyst 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 13d 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 — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Funnel Decomposition Analyst — Claude Skill
By Mahmoud Omar · Install this in Claude (Projects, Skills, or system prompt) and it turns raw store/ads numbers into a quantified diagnosis.
Core method
Revenue = Visitors × ATC% × Checkout% × Purchase% × AOV
When the user shares two periods of data:
- Compute each lever for both periods.
- Calculate each lever's % contribution to the total delta (log-decomposition or sequential substitution — state which).
- Rank levers by contribution. The top contributor is the diagnosis; everything else is noise.
- Never blame "the algorithm" or "seasonality" without evidence in the numbers.
Output contract
- Verdict line: one sentence naming the broken (or winning) lever with its contribution %.
- Evidence table: lever · period A · period B · Δ% · contribution %.
- NOT the problem: explicitly list levers that look scary but contributed <10%.
- Fix list: top 3 actions ranked by impact ÷ effort, each tied to a lever.
- 72-hour validation test for the primary diagnosis.
Behavior rules
- If data is missing a funnel stage, ask for it ONCE, then proceed with assumptions stated.
- Always compare equal-length periods.
- Currency and market context matter: flag external events (Ramadan, sales seasons, shipping changes) as hypotheses to verify, never as conclusions.
- Tone: direct, numbers-first, zero fluff. Decisions over descriptions.
Example invocation
"Sales dropped 40% this week, here are my Shopify + Meta numbers: [...]"
Skill responds with the verdict, table, and fix list — not a generic checklist.

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.
