📝 Walkthrough

Walkthrough

Adds end-to-end job artifact tracking for the Claude Code chat agent. New ChatJobArtifactResponse (Python) and ClaudeCodeChatJobArtifact (TypeScript) types are introduced. Backend record_tool_artifacts routes job_progress and studio_link (destination=job) tool inputs into job artifacts. Frontend state management, API parsing, and history panel rendering are extended to handle jobs. Agent system prompts are updated to prefer Studio UI over CLI commands.

Changes

Job Artifact Feature

Layer / File(s)	Summary
Job artifact type contracts web/.../ClaudeCodeChatRoute/types.ts, services/studio/src/nmp/studio/coding_agent_artifacts.py	ClaudeCodeChatJobArtifact interface and ChatJobArtifactResponse Pydantic model introduced; ClaudeCodeChatArtifacts and ChatArtifactsResponse extended with jobs arrays.
Backend job artifact recording services/studio/src/nmp/studio/coding_agent_artifacts.py	_upsert_job_artifact and _append_job_artifact helpers added; record_tool_artifacts updated to route studio_link (destination="job") and job_progress inputs into artifacts.jobs.
Frontend artifact state management web/.../ClaudeCodeChatRoute/artifacts.ts	jobs initialized in createEmptyClaudeCodeChatArtifacts and cloneArtifacts; upsertJob, buildJobHref, recordJobArtifact helpers added; recordToolArtifacts handles job_progress/__job_progress inputs.
API deserialization of job artifacts web/.../ClaudeCodeChatRoute/api.ts	parseJobArtifact helper added; parseChatArtifacts extended to map value.jobs into the returned artifacts object.
History panel job artifact rendering web/.../ClaudeCodeChatRoute/ClaudeCodeHistoryPanel.tsx	getJobArtifactHref and JobArtifacts renderer added; hasArtifacts guard and ClaudeCodeArtifactsPane updated to include job artifact display.
Agent prompt guidance services/studio/src/nmp/studio/coding_agent_mcp_tools.py, services/studio/src/nmp/studio/coding_agents.py	System prompts updated to prioritize NeMo Studio MCP tools/views over CLI commands; CLI use restricted to cases without a Studio UI equivalent or explicit user request.
Tests services/studio/tests/unit/test_coding_agents.py	Fixture adds mcp__nemo_studio__job_progress tool-use event; expected chat_artifacts updated with jobs block; streaming test asserts new prompt guidance strings.
