+# ITC-WP-0017 — AgenticDrivesFunctional PracticePattern
+
+## Goal
+
+Name and document the practice of using agentic cross-repository work records
+as a flexible demand-discovery channel, then converting repeated, stable demand
+into direct functional service interfaces that reduce latency, token use, cost,
+and approval relays.
+
+## T01 — Define the practice
+
+```task
+id: ITC-WP-0017-T01
+status: progress
+priority: high
+```
+
+Document the context, forces, solution, feedback dynamics, invariants, evidence,
+consequences, and failure modes. Preserve repository ownership and explicit
+third-party approval boundaries while making the direct-interface-first rule
+clear.
+
+## T02 — Register and publish the pattern
+
+```task
+id: ITC-WP-0017-T02
+status: pending
+priority: medium
+```
+
+Register the artifact and its relationship to `InterfaceDeprecationStrangler`,
+add it to the pattern catalog, refresh generated retrieval assets, and validate
+the canon.
+
+## Acceptance
+
+- [ ] `AgenticDrivesFunctional` conforms to PracticePattern v0.1.
+- [ ] The pattern distinguishes direct interfaces from cross-repo task routing.
+- [ ] Repetition is treated as evidence for interface review, not an automatic
+      mandate to build an interface.
+- [ ] Interfaces preserve authorization, credential custody, and third-party
+      approval boundaries.
+- [ ] The pattern is registered, retrieval-visible, validated, committed, and
+      synchronized.
+
+## Out of scope
+
+- Implementing a new service API, CLI, or MCP interface in a consumer repo.
+- Defining one universal numeric threshold for interface extraction.
+- Replacing agentic communication for novel, ambiguous, or exceptional work.
