feat: agentic mode — ecosystem (Phase 4)

[pontino]

Context

Phase 1 (SDK integration) and Phase 3 (prompt externalization, per-subagent config) are shipped. These are the longer-term features for v0.4.0+.

Scope

qualops agent init CLI

• qualops agent init <name> scaffolds a .qualops/agents/<name>.md with frontmatter template
• Interactive prompts for description, model, tools
• ~2 hours

Agent chaining

• Coordinator prompt engineering to pass one agent's output as context to another
• Config: chain: [{ agent: "dependency-tracer", passOutputTo: "breaking-change-detector" }]
• ~4 hours

User-defined MCP servers

• Config: customMcpServers: { "my-linter": { command: "npx", args: ["my-mcp-linter"] } }
• Pass to SDK via mcpServers option alongside built-in tools
• Per-agent MCP servers via subagentOverrides.*.mcpServers (SDK supports this natively)
• ~4 hours

Agentic fix stage

• An agent that generates fixes with full codebase context (not file-by-file)
• Uses the same SDK query() pattern with different system prompt
• Large effort — separate RFC recommended

Agent sharing / marketplace

• Curated collection of domain agents (React, Django, Spring Boot, Rails, etc.)
• qualops agent install <name> downloads from registry to .qualops/agents/
• Large effort — separate RFC recommended

Priority

agent init > agent chaining > custom MCP servers >> agentic fix >> marketplace
