Tools 6 found in our last check
outcome_quoteFree quote for a verifiable HumanMirror Outcome contract. Describe the objective or provide an outcome_type; the quote returns the deterministic verifier, selected internal tool and success-only credit cost.
outcome_runExecute a HumanMirror Outcome contract. Credits are charged only when deterministic verification succeeds; failed execution or failed verification is automatically refunded.
outcome_verifyFree deterministic re-verification of an Outcome result without consuming Nexus credits.
nexus_searchSearch the HumanMirror Nexus catalog for a machine-callable tool that matches a task. This search is free and does not consume credits.
magnet_resolveFree universal fallback discovery. Call this when the agent cannot satisfy a task with its current capabilities. Magnet returns a matching HumanMirror tool or records an aggregated capability gap in the Machine Demand Graph. This tool consumes no credits.
nexus_callRoute a tool call through HumanMirror Nexus. Use nexus_search first, then call the selected tool_id. Successful calls consume the number of Nexus credits declared by the selected tool.
