Capabilities

Tools

6 tools
calculate_view
Run a financial calculation with the provided input values. Pass field values as a dict mapping field names to values. Use the types from get_view_signature: amount fields take numbers (e.g. 300000), percent fields take decimals (0.05 = 5%), count fields take integers, yesno fields take true/false. Args: owner_username: The view owner's username viewname: The view's URL slug inputs: Dict of field_name -> value for input fields

Input schema 
{'type': 'object', 'title': 'calculate_viewArguments', 'required': ['owner_username', 'viewname', 'inputs'], 'properties': {'inputs': {'type': 'object', 'title': 'Inputs', 'additionalProperties': {'anyOf': [{'type': 'number'}, {'type': 'integer'}, {'type': 'string'}]}}, 'viewname': {'type': 'string', 'title': 'Viewname'}, 'owner_username': {'type': 'string', 'title': 'Owner Username'}}}
get_pulse
Get the current FinFam Pulse — FinFam's twice-daily money-news digest. Use this for "what's happening in finance / markets / the economy right now" questions instead of answering from memory. Returns a dated headline and paragraph, the overall mood, a finfam.app permalink, the external grounding sources, and the edition's story cards (each with its own article URL). Cite the permalink and the story URLs. Returns null when nothing is published yet. Args: period: 'today' for the latest daily read, 'week' for the running weekly read

Output schema 
{'type': 'object', 'title': 'get_pulseOutput', 'required': ['result'], 'properties': {'result': {'anyOf': [{'type': 'object', 'additionalProperties': True}, {'type': 'null'}], 'title': 'Result'}}}
get_view_signature
Get the full input/output contract for a financial calculator. Returns field names, types, defaults, and hints so you know exactly what inputs to collect from the user before running a calculation. Args: owner_username: The view owner's username (from search results) viewname: The view's URL slug (from search results)

Input schema 
{'type': 'object', 'title': 'get_view_signatureArguments', 'required': ['owner_username', 'viewname'], 'properties': {'viewname': {'type': 'string', 'title': 'Viewname'}, 'owner_username': {'type': 'string', 'title': 'Owner Username'}}}
get_view_source
Get the source code/formulas of an open-source financial calculator. Only available for views that have been published as open-source. Returns the calculation logic as a readable TSV showing fields, types, defaults, and formulas. Args: owner_username: The view owner's username viewname: The view's URL slug
Read only Idempotent
Input schema 
{'type': 'object', 'title': 'get_view_sourceArguments', 'required': ['owner_username', 'viewname'], 'properties': {'viewname': {'type': 'string', 'title': 'Viewname'}, 'owner_username': {'type': 'string', 'title': 'Owner Username'}}}
search_pulse
Search past FinFam Pulse editions by topic (e.g. "Fed", "mortgage rates", "layoffs"). Matches both the editions' prose and their individual story cards. Each result is one dated edition with its headline, paragraph, permalink, sources, and the story cards that matched. Best match first, newest as the tiebreak. Args: query: Topic or keywords to match days: How many days back to search (default 30, max 365) limit: Maximum number of editions to return (default 5, max 20) category: Optional card category filter — one of markets, rates, housing, jobs, spending, debt, money_drama, human_interest, retirement, taxes
