What it does

Market Share Tracking is an agent skill from agentii-ai/agentii-investment-intelligence. Weekly product-level commercial tracking — TRx/NRx with current/4-wk/12-wk share and YoY, launch curves overlaid with same-class analogs plus a consensus-implied trajectory, LOE/biosimilar erosion series, GTN/net-price stress brackets, and per-row data-caveat discipline. Use to track any launched drug, biologic, device, or vaccine against its class and consensus.

Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/knowledge-frameworks.md` and `references/modes.md`).

The repository describes itself as: Claude-type skills for institutional equity research — 25 AI agent skills with SEC filings, XBRL financials, earnings calendars, DCF/comps/LBO models, and PPT generation. Powered… The licence is Apache-2.0.

When your agent uses it

  • Track any launched drug
  • Vaccine against its class and consensus

Example prompts

  • “/market-share-tracking”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. search_commercial_track — weekly track rows with stored previous values.
  2. Company-reported product sales: 10-K/Q XBRL (get_statement) and MD&A (search_documents).
  3. Transcript commentary on scripts/share/persistence via search_documents.
  4. Payer coverage/PA announcements and openFDA label events via search_documents + list_sources.
  5. Consensus: search_earnings_calendar company-level only; licensed Rx panels never assumed.

What it can do on your machine

Read from SKILL.md and the folder at commit 86980e1. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Market Share Tracking loads about 1.9k tokens when it runs, and up to ~3.4k if it reads all its reference files. Until then it costs about 97 tokens; SKILL.md has 713 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~97
When it runs · the whole SKILL.md, loaded when a task matches
~1.9k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~3.4k

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.

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.

Data Source Priority

  1. search_commercial_track — weekly track rows with stored previous values.
  2. Company-reported product sales: 10-K/Q XBRL (get_statement) and MD&A (search_documents).
  3. Transcript commentary on scripts/share/persistence via search_documents.
  4. Payer coverage/PA announcements and openFDA label events via search_documents + list_sources.
  5. Consensus: search_earnings_calendar company-level only; licensed Rx panels never assumed.

Methodology

Retrieval Scope

unstructured_document_search

Retrieval Strategy
  1. Resolve basket tickers via search_companies; map products to companies.
  2. Pull weekly rows via search_commercial_track (previous values stored alongside).
  3. Compute the three-window lattice from stored history; attach per-row caveats.
  4. Build the launch board: ≥2 named analog curves + consensus-implied trajectory arithmetic.
  5. LOE events: pair entrant share with branded YoY decay; date approval/launch.
  6. Stress net price (GTN brackets, $/Rx, channel mix); label derived values [DEDUCTED].
  7. Ground in knowledge (sectors=med); cite /v/ records.

Temporal Scope

See frontmatter temporal_scope block. Rolling windows recompute from stored history; holiday weeks are labeled.

Tool Allowlist

See frontmatter allowed_tools.

Protocol
  1. Ticker + product resolution
  2. Commercial-track pull (stored history)
  3. Three-window lattice computation
  4. Launch-board overlay + implied trajectory
  5. LOE erosion series (when applicable)
  6. GTN/net-price stress + caveat audit

Modes

  • Drug / biologic (default): scripts/share/erosion; LOE/biosimilar series.
  • Device: installed base, placements/procedures, utilization, ASP; no script numbers.
  • Vaccine: doses/serials, procurement, ACIP-cohort uptake; approval ≠ commercial availability.
  • Basket: multi-ticker watchlist with per-name sections.

  2. Launch Board — actuals vs ≥2 named analogs + consensus-implied path with stated arithmetic
  3. Share & YoY Lattice — current/4-wk/12-wk share and YoY with previous values
  4. LOE / Erosion Series — entrant share vs branded YoY decay with approval/launch dates
  5. Net-Price & GTN Stress — $/Rx, GTN brackets, channel mix, [DEDUCTED] labels
  6. Caveat Register — per-row annotations + coverage_gap list
  7. Coverage Gaps — missing sources and degraded modes

Error Handling
