Pulled straight from the server with tools/list on 2026-10-17.
get_company_fileread-only

One covered company's living research file (company_file.v1): business, three drivers, the last eight fiscal quarters from SEC XBRL with provenance on every number, the desk's own estimates and revision log, the thesis and what changes it, the market-memory bands or an explicit coverage 'none', published notes, and the scorecard. symbol is a stock ticker; optional as_of (YYYY-MM-DD) r

get_company_statusread-only

Current monitoring alongside the immutable company file. Preserve scan versus review clocks, pending discovery leads, source failures and limitations. Never use current monitoring as historical evidence or as approval to promote a company. No arguments other than a ticker.

get_company_revisionsread-only

Browse immutable published versions, reasons and pinned JSON/CSV links. Follow next_offset.

compare_company_revisionsread-only

Compare facts, assumptions, scenarios and thesis between immutable revisions. Omit to_revision for latest.

run_company_scenarioread-only

Calculate a temporary scenario from 1-20 assumption cell IDs and numerical values in their published units. Read get_company_file first. Reported facts, guidance and the published revision stay unchanged. Preserve limitations and identify user assumptions. No recommendation or valuation is implied.

check_company_forecastsread-only

Compare frozen revenue forecasts with reported results. Forecasts must precede quarter end. Missing results and definition mismatches remain unavailable. This is not market-memory calibration.

compare_company_historyread-only

Two to six companies, one quarter end (YYYY-MM-DD), USD history and provenance. Mismatched source concepts or missing history never become comparable numerical values.

get_company_watchlistread-only

Latest model revisions, current review status and qualified checkpoints for 1-20 companies. No list is saved on the server. Compare revisions with your own last-seen markers. This reads published research, not new source checks or live quotes. Preserve unavailable rows.

list_coverageread-only

The research hub's coverage universe: clusters and symbols, with each symbol's company-file revision, as_of date, whether a compiled file exists, and skeleton=true when the authored half is empty. file=true is not coverage. No arguments. Read a file with get_company_file(symbol).

market_stateread-only

One call: completed-session state, tape, historical analogs, outcome ranges and transition memory. symbol is a stock ticker; optional date is YYYY-MM-DD. Omit date for the latest built session, not real-time prices. Preserve status, sample sizes, dates, informative receipts, meta.warnings and meta.context_quality (missing tape fields, descriptive industry label and provenance). Ve

daily_noteread-only

Read the published daily research, its selection rule and settled-note tally in one call. No arguments needed. Optional date (YYYY-MM-DD) selects a published session. A missing note or unsettled outcome is unavailable evidence, not zero. The note is research selected by a disclosed rule, not a stock-pick list.

research_qualityread-only

Read the published five-session calibration receipt; no arguments or earlier tool call needed. Preserve the receipt's dates, sample sizes and qualifications. Coverage applies to the calibrated cohort-band method and population named in the response, NOT automatically to market_state's empirical excess ranges, all research, or future returns. Daily-note results have a separate tall

search_researchread-only

Find published studies, Casebook and agent protocols by keyword. kind: all, study, casebook or agent_protocol. limit 1-20; use next_offset for more results. Returns exact IDs, findings, verdicts, dates, samples and document versions. Partial status means one publication source was unavailable. Proposed protocols are not findings. This is document search, not analog ranking. Di

read_researchread-only

Read a publication ID returned by search_research, preserving its evidence. source_fields returns exact catalog status/receipt fields; content.source_rows exposes literal result tables/mappings with source positions and heading scope. These are source projections, not AI conclusions. Missing parsed rows do not establish absence of a result. Use the text/guide for interpretation an
