41 tools

• list_datasets

  List available Taiwan-market datasets (discovery entry point). Returns id / 中文名 / category / tier / one-line description for each. Use this first to find the right data. Args: category: optional, e.g. 'chip'(籌碼) 'fundamental'(基本面) 'price'(行情) 'macro'(總經)…

• describe_dataset

  FULL semantics of one dataset: grain (what a row is), field meanings+units, ★TIME-CORRECTNESS rules (knowledge_time_field / point_in_time_safe — read before backtesting), relations for cross-table reasoning, agent_hints (when to use), quant_use (which factors). Args…

• query_dataset

  Query rows with built-in look-ahead protection. ★ POINT-IN-TIME: pass `as_of` (YYYY-MM-DD) for backtesting/agent-learning. For non-point-in-time-safe datasets (fundamentals, monthly_revenue, dividend_policy…) rows are filtered by DISCLOSURE date <= as_of, so the…

• find_related

  Traverse the knowledge graph for cross-table / supply-chain reasoning. - dataset_id: returns join-able datasets (+why) to plan multi-table analysis. - ticker: returns its industry value-chain node + peers in the same node (supply-chain reasoning). Args: dataset_id…

• search_filings

  Semantic search over MOPS filings, financial-statement notes and company news. Answers questions a keyword filter cannot: "what risks did this company disclose this quarter?", "which companies mentioned CoWoS capacity expansion?" — matching on MEANING, so a paragraph…

• explain_provenance

  Where did this number come from, and when could anyone have known it? (WP-6) ★ THIS IS THE GROUNDING TOOL. Every other tool's answer is supposed to be expandable through this one: given a ticker, a field and a date, it names the dataset that serves that field, the…

• get_inclusion_proof

  Prove a row was in the snapshot TWMD published — and check it yourself. Returns the Merkle sibling path, the signed root, and the checkpoint it belongs to. It returns the PATH rather than a yes/no on purpose: a service that answers "yes, it is included, trust me" is…

• cite_this

  Produce a bibliographic citation for TWMD data — APA, BibTeX, and a re-verifiable token. ★ FOR PAPERS, REGULATORY FILINGS AND ANYTHING A REVIEWER WILL RE-CHECK LATER. A dataset is corrected, backfilled and re-run. Three years from now a reviewer opening our API sees…

• read_primary_text

  Read the FULL TEXT of filings and announcements — with proof links and a knowledge cutoff. ★ NOT `search_filings`. That one ranks passages by similarity and hands you fragments; this hands you whole documents so you can read what was actually said and where it sat in…

• ask

  Answer a plain-language question in Taiwanese-market vocabulary, sentence by sourced sentence. ★ FOR BEGINNERS WHO DO NOT KNOW WHICH DATASET THEY WANT. Ask "PBR 是什麼" or "什麼叫漲跌停" in ordinary words; routing happens on our side. `describe_dataset` explains a table you…

• chart

  Turn rows you already fetched into a Vega-Lite drawing your chat window can render. ★ IT DRAWS; IT DOES NOT FETCH. Hand it the output of `query_dataset` — this tool never touches the database, so it cannot bypass the `as_of` filter those rows were selected under. A…

• screen

  Post-process rows already returned by query_dataset; without rows it returns a clear hint. Turn a spoken shortlist description into explicit numeric cut-offs, and show the cut-offs. ★ THE THRESHOLDS COME BACK WITH THE SHORTLIST. "低本益比" becomes `per < 15`, and that 15…

• query_regime

  The Taiwan business-cycle light (NDC monitoring indicator) as a monthly series. ★ THIS IS A REVISED FIGURE, NOT A POINT-IN-TIME ONE. Every response carries `revision_basis: as_revised`. Our source holds exactly one row per month — the CURRENT value, not the value as…

• calendar

  Sort corporate dates into what is still ahead and what has already passed. ★ TWO DATES, NOT ONE. What is "upcoming" is decided by the date the event HAPPENS; `as_of` filters on the date it was ANNOUNCED. An ex-dividend declared on 2026-08-01 for 2026-09-15 is both…

• compare

  Lay two to five named companies side by side on the same measures, gaps marked as gaps. ★ AN ABSENT FIGURE STAYS ABSENT, AND THE COMPANY STAYS ON THE TABLE. A blank cell is reported as `available: false`, never filled with a zero, a previous period, or by quietly…

• get_code_example

  Emit a copy-pasteable HTTP snippet wired to the real endpoint, header and parameter names. ★ FOR WRITING YOUR OWN CLIENT, NOT FOR GETTING DATA. Every other tool here answers a question; this one hands you source code so your program can ask it directly over HTTPS…

• run_recipe

  Replay a saved multi-step routine over rows you fetched, with every step listed. ★ THREE ROUTINES: `momentum_scan` (rank by a return column), `earnings_surprise` (actual versus estimate), `dividend_capture` (which ex-dates are still ahead). ★ A SAVED ROUTINE IS NOT…

• try_sample

  Hand an unregistered caller a short taste of an open dataset, plus where to unlock the rest. ★ WHAT AN ACCOUNTLESS CALLER GETS INSTEAD OF A BARE REFUSAL. Somebody arriving through a chat connector with no plan would otherwise meet a flat rejection, which the host model…

• run_backtest

  Submit a point-in-time backtest. NON-BLOCKING: returns a run_id at once; poll get_backtest. `job_status` tells you where it is: `cached` (this exact backtest was already computed — the stored result is returned immediately), `done` (it finished within…

• get_backtest

  Retrieve a previous backtest by run_id — the full record, including why it was rejected. Only runs in YOUR namespace are visible; a run_id belonging to someone else is simply not found. Args: run_id (the `twmd_bt_…` handle returned by run_backtest).

• replay_backtest

  Re-run a stored backtest and report whether it still produces the same numbers. Same spec, same `as_of`, same data questions. If the numbers moved, either the engine version changed or the underlying data was restated — both are reported, neither is…

• list_backtests

  Browse an INDEX of your past backtest runs — ids and headline metrics only, no re-execution. Use when you want to find a run whose id you have forgotten. It never re-computes anything: `run_backtest` executes a new one, `get_backtest` opens a single record in…

• memory_save

  Remember something, with its sources and its knowledge time. Nothing is ever overwritten: saving a `factor_def` or `watchlist` under an existing key SUPERSEDES the previous version (both rows survive, so "what did I believe in June?" stays answerable)…

• memory_search

  Recall your own memories — hybrid (semantic + exact-term), with provenance attached. Every result carries where it came from (`source_query_ids`, replayable), when it was believed (`valid_from`/`valid_to`) and what knowledge time it is about (`as_of`), plus a…

• memory_get_watchlist

  Read the tickers on one named watchlist, as it stands right now. A curated roster you maintain — distinct from `memory_search`, which digs through everything you ever recorded, and from `list_alerts`, which is about price triggers rather than symbols you…

• memory_replay_query

  Re-run a remembered query by its `twmd_q_…` id, through the read API's own replay store. This is what makes a recalled finding checkable: the memory says where it came from, and this fetches that same data again. It never re-executes the query by another route…

• run_research

  Run a multi-agent research pass and return a structured, sourced report. Six roles run in order — data analyst, factor researcher, backtest engineer, risk officer, portfolio manager, compliance officer. Each step's output carries the `query_ids` behind it…

• get_research

  Retrieve one of YOUR previous research reports. Others' runs are simply not found. Args: research_id — the identifier `run_research` returned when it started that run.

• list_pending_actions

  Financial actions proposed by your research runs that are waiting for a human decision. Nothing here has been executed or ever will be by this system. These are proposals.

• approve_action

  Record a HUMAN's approval of a proposed action. This writes an audit record naming who approved what, and when. It does NOT execute the action: TWMD has no order or funds path, by design. Execution, if any, happens elsewhere and is performed by a person…

• list_alerts

  Show the price-trigger rules you have armed, and whether each is still armed. A read-only inventory of thresholds you asked to be watched — it arms nothing and cancels nothing (`set_price_alert` arms, `delete_alert` cancels). Another customer's triggers are…

• set_price_alert

  Leave a standing instruction: tell me when this symbol crosses this price. The alert OUTLIVES this conversation. It is evaluated against official daily closes by a resident agent and delivered to your realtime stream and to any webhook endpoints you have…

• delete_alert

  Cancel one armed price trigger permanently, by its rule id. Disarms a single watch so it will not fire again — the opposite of `set_price_alert`, and unlike `list_alerts` it changes state rather than reporting it. Cancellation is irreversible: re-arming…

• risk_assess

  Measure a portfolio you state against limits you state, on official point-in-time prices. Reports concentration and peak-to-trough drawdown, and NAMES every position it could not price rather than quietly assessing the rest — an assessment covering 60% of a…

• agent_activity

  What YOUR agents have actually done, from the durable audit trail. Every resident agent records what it did and ON WHAT BASIS — the rule and the two closes behind an alert, the coverage and limits behind a risk finding, the run_id and declared trial…

• list_factor_findings

  Verdicts from the overnight factor search on YOUR namespace — including the rejections. The rejections are returned deliberately. A research log that keeps only the winners is the highlight reel overfitting lives in, and the acceptance RATE is the number that…
