What it does

Epi Demand Funnel is an agent skill from hh-health-AI/healthcare-equity. This skill should be used when the user asks for "TAM", "addressable population", "peak sales", "epi model", "how many patients", "bottoms-up market size", "penetration assumption", or wants to build or stress-test the patient funnel underneath a revenue forecast.

Its SKILL.md is about 820 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/funnel-sources.md`).

It sits in Testing & QA, covering Load testing. The repository describes itself as: Synthesis engine for buy-side healthcare equity research. The licence is MIT.

Context cost

Epi Demand Funnel loads about 822 tokens when it runs, and up to ~1.5k if it reads all its reference files. Until then it costs about 71 tokens; SKILL.md has 417 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~71
When it runs · the whole SKILL.md, loaded when a task matches: ~822
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~1.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Epidemiology demand funnel

Build the patient funnel underneath a peak-sales number, sourcing every step separately and showing where the estimate is actually fragile.

Workflow

Fix the population base. Incidence for acute or newly-diagnosed populations; prevalence for chronic ones. Getting this wrong is a first-order error: an incidence drug modelled off prevalence overstates by the disease duration. Sources: SEER for cancer, CDC WONDER for mortality and natality, NHANES and BRFSS for prevalence of chronic conditions, USRDS for dialysis, published registries for rare disease.
Apply the diagnosis rate, with a source. This is where funnels break. Many chronic diseases run diagnosis rates well below half. If no diagnosis rate is available, say so, use a range, and flag the funnel as unanchored at this step.
Apply label eligibility. Line of therapy, biomarker prevalence, severity threshold, age band, contraindications. Biomarker prevalence should come from the literature and, where available, from ChEMBL or genomic databases — not from the company's investor deck.
Apply the treated rate, then share, then duration and adherence. Persistence is the most commonly over-assumed variable in chronic therapy models; real-world discontinuation frequently runs far above trial discontinuation.
Apply net price per patient-year, taken from rx-utilization → gross-to-net-bridge rather than from list price.
Show the sensitivity. Identify the two steps with the widest ranges and tornado the peak-sales figure against them. The output the desk needs is not a point estimate but "peak sales is $2.1bn ± $900m, and almost all the variance is diagnosis rate and persistence".
Cross-check against the coded procedure or claims view. a procedure-exposure engine → exposure-map gives an ICD-10-anchored count. If the epidemiological funnel and the coded volume disagree by more than a factor of two, one of them is wrong and the funnel is usually the guilty party.
Instrument it. Name the observable that would confirm the funnel post-launch — typically SDUD or Part D volume at a stated month — and hand it to the watcher.
Emit the brief.

Where funnels go wrong, in order of frequency

Skipping the diagnosis rate.
Prevalence used for an incidence-driven product.
Trial persistence applied to the real world.
Biomarker prevalence taken from the sponsor's deck.
Assuming the eligible population is the treated population.
Ignoring competitive share loss at the exact point of peak.

Not-automatic

An epidemiological funnel does not license a revenue forecast on its own. Without an observed volume series to calibrate against, it is an upper bound with a shape.
