Available Tools (19)

Public (no key required)

Tool	Description
canuckduck_search	Search 1,334 Canadian policy variables by keyword. Use first to find variable IDs for graph traversal.
canuckduck_stats	Graph summary statistics: variables, edges, organizations, cases, constitutional doctrines. Use to ground responses about graph scope.
canuckduck_geo_lookup	Look up any Canadian postal code or FSA code. Returns community name, city, province, and coordinates. Example: 'T2P 3H5' returns 'Downtown Commercial Core, Calgary, AB'.
canuckduck_geo_stats	Geographic data coverage: FSA codes, municipalities, federal ridings, postal codes, communities.

Registered (free API key)

Tool	Description
canuckduck_forward	Trace what a policy variable CAUSES downstream. Use to answer: 'If we change X, what else changes?'
canuckduck_backward	Trace what CAUSES a policy variable upstream. Use to answer: 'Why is X happening?' or 'What drives X?'
canuckduck_paths	Find all causal paths connecting two policy variables. Use to answer: 'How is X connected to Y?'
canuckduck_impact	Full causal impact radius — all downstream and upstream relationships scored by influence weight.
canuckduck_evidence	Source evidence and CanLII case citations supporting a causal relationship. Use when sourcing is needed.
canuckduck_news	Canadian news articles from government and media RSS feeds, filtered by policy topic.
canuckduck_geo_variables	Find RIPPLE variables scoped to a specific Canadian province. Returns provincial + national variables.
canuckduck_local_impact	Run a policy scenario and localize impacts to a specific community. Answers: 'What does this mean for MY community?'
canuckduck_propose	Propose a new variable, causal edge, or evidence to the RIPPLE graph. Enters a review queue — nothing modifies the active graph until approved.
canuckduck_review_queue	List pending graph proposals, check status, or approve/reject proposals.

Professional (paid key)

Tool	Description
canuckduck_constitutional	Explore 46 Canadian constitutional doctrines with connected policy variables. Covers Charter rights, division of powers, Duty to Consult.
canuckduck_root_trace	Trace a variable to constitutional roots with CanLII case citations and legal precedents.
canuckduck_cda_profile	Constitutional Divergence Analysis profile: pressure scores, Charter divergence, linked legal precedents.
canuckduck_simulate	Multi-variable policy scenario simulation with projected values, constitutional warnings, and geographic context.
canuckduck_gaps	Observatory gap analysis: graph health score, search miss clusters, path failures, simulation anomalies, evidence voids.
