market-share-tracking

market-share-tracking is a skill for Claude Code from agentii-ai/agentii-investment-intelligence. It costs 92 tokens per session (1,870 once invoked), scanned A, original, Apache-2.0.

A weekly commercial-tracking tool for measuring a medicine's prescriptions, market share, growth, launch progress, competitors, and loss of exclusivity. TRx means total prescriptions, and NRx means new prescriptions.

In plain words
What is it for?
Use it to compare a product with same-class products, track launch performance and prescription share, assess biosimilar effects, and test net-price assumptions.
Why use it?
It puts sales trends, competitor comparisons, patent-related erosion, and pricing assumptions in one view with caveats for each data row.

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

market-share-tracking 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 1mo 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 — 164 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Methodology inspired by publicly taught commercial-tracking approaches; all text is an original paraphrase.

Defaults

Parameter Default Value Rationale
windows current / 4-wk / 12-wk Three-window share + growth lattice
growth_metric TRx YoY Weekly, 4-wk, and 12-wk YoY alongside share
analog_count 2 ≥2 named same-class analogs on the launch board
consensus_source company-level Product consensus via segment-share math [DEDUCTED]
caveats per-row A number without a caveat annotation is a defect

Preflight

Run canonical pre-flight per contracts/preflight.md. Include the X-Agentii-Trace header on every tool call per contracts/x-agentii-trace-header.md — carry the _run_id from your first tool result and name yourself (and your parent, if you were spawned). Confirm ticker resolution via search_companies before commercial-track queries.

Triggers

  • "Is [product] tracking above or below consensus?"
  • "How is the [product] launch trending?"
  • "Build the launch board for [product] with class analogs."
  • "What is the consensus-implied trajectory for [product]?"
  • "Show [product]'s TRx share and YoY for the last 12 weeks."
  • "How fast is [biosimilar] eroding [branded product]?"
  • "Stress-test [product]'s net price and GTN."
  • "What are the caveats on [product]'s scripts?"
  • "Track installed base and utilization for [device]."
  • "How is ACIP-cohort uptake tracking for [vaccine]?"

Production Grounding

  • Three-window lattice: current / 4-wk / 12-wk share and YoY; previous values shown next to new values.
  • Launch boards: actuals vs ≥2 named same-class analogs + consensus-implied trajectory (consensus sales ÷ net price ÷ script duration → required TRx → linear path); assumptions stated.
  • LOE erosion: entrant share vs branded YoY decay with approval/launch dates.
  • GTN/net-price stress: GTN brackets (50→80% flex), $/Rx = quarterly sales ÷ scripts, channel mix; half-of-sales-minus-volume net price is a stated judgment [VIEW].
  • Modality vocabularies: scripts/share/erosion (drugs & biologics); installed base, placements/procedures, utilization, ASP (devices); doses/serials, procurement, ACIP-cohort uptake (vaccines); never a script number for a device or vaccine.
  • Per-row caveats: restricted scripts, rounding, indication-mixed, IV invisibility, holiday weeks — every row carries its caveat or coverage_gap.
  • Badges: [FACT]/[DEDUCTED]/[VIEW] with the summary table.

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.
