📝 Walkthrough

Walkthrough

ADR-0016 is refined to specify a clearer staged PR execution sequence with explicit ownership boundaries between agentkit reusable primitives and coding_agent concrete integrations. PR 1–4 descriptions are updated with distinct responsibilities around environment, runtime context, tool governance, and inbound messaging. Acceptance criteria and rejected alternatives are revised to reflect the new partitioning and deferral rules.

Changes

ADR-0016 Staged PR Sequencing and Ownership Boundaries

Layer / File(s)	Summary
Decision Framework & Ownership Boundaries coding-agent/docs/adr/0016-stage-environment-runtime-and-tool-orchestration-prs.md (lines 14–67)	Replaces PR-sequence text with a detailed agentkit vs coding_agent ownership boundary framework and an updated ordered plan for PR 1–4, specifying what each PR implements and what sourcing remains deferred to session runtime metadata (PR 86).
Inbound Runtime Messaging & Idempotency coding-agent/docs/adr/0016-stage-environment-runtime-and-tool-orchestration-prs.md (lines 69–75)	PR 4 description now explicitly enumerates inbound runtime message types (interrupt, user steering, approval decision, subagent message, system notice) with idempotency/consumption semantics.
Follow-on PR Staging & Subagent Deferral coding-agent/docs/adr/0016-stage-environment-runtime-and-tool-orchestration-prs.md (lines 77–93)	Introduces PR 5 tool proxy governance notes and clarifies that generic subagent foundations may move to agentkit, while full coding subagent orchestration remains in coding_agent until stability conditions are met.
Acceptance Criteria & Rejected Alternatives coding-agent/docs/adr/0016-stage-environment-runtime-and-tool-orchestration-prs.md (lines 94–118)	Expands "Parallel agents," "Alternatives Rejected," and "Acceptance Criteria" sections to align with refined boundaries, explicitly deferring cloud execution and full subagent orchestration, and detailing which subagent primitives may move to agentkit.

Sequenced with wisdom, one PR per day! ✨
