name: cc-sdd-new-agent description: Add or extend coding-agent support in cc-sdd by executing the SOP in docs/cc-sdd/sop-new-agent.md end-to-end. Use when introducing a new agent, adding a subagent-capable variant, or evaluating migration of an existing supported agent to skills-based templates.

CC-SDD New Agent Integration

Goal

Add a production-ready agent integration to tools/cc-sdd with complete research, implementation, and verification artifacts. Use the existing SOP and templates in this repository instead of inventing a new process.

Default Operation Mode

Use plan-first as the default:

• First deliverable: docs/cc-sdd/plans/agent-plan-{agent-id}.md
• Second deliverable (after plan approval): implementation changes in tools/cc-sdd/...

Do not skip the plan document unless the user explicitly requests direct implementation.

Collect Inputs First

Collect the minimum inputs before editing files:

• Target agent display name and agent id (kebab-case)
• Official documentation URL for command/agent/skills format
• Integration scope: commands-only, commands+agents, or skills
• Whether work type is new-agent or migration

If any item is unclear, resolve it during Phase 1 research before creating implementation files.

Execution Workflow

1) Run Phase 1 Research

Read docs/cc-sdd/sop-new-agent.md and extract all required spec details from official docs:

• commands directory
• agent directory (if supported)
• documentation filename
• command invocation format
• YAML frontmatter schema for commands and agents (or skills)
• placeholders/arguments format

Record exact values (not assumptions) in the plan document.

2) Create Plan Document

Copy and fill:

• docs/cc-sdd/templates/agent-plan-template.md

Include:

• Phase 1 research summary table
• Differences vs nearest existing agent pattern
• 5-step implementation plan
• changed-file list
• verification plan

Write the completed plan to:

• docs/cc-sdd/plans/agent-plan-{agent-id}.md

Before implementation, ensure the plan explicitly states:

• integration scope (commands-only, commands+agents, skills)
• whether this is new-agent or migration
• compatibility impact and rollback approach

3) Choose Base Pattern and Implement

Pick the nearest existing implementation and copy from it:

• commands-only: start from tools/cc-sdd/templates/agents/codex or another commands-only agent
• commands+agents: start from tools/cc-sdd/templates/agents/claude-code-agent or tools/cc-sdd/templates/agents/opencode-agent
• skills: start from tools/cc-sdd/templates/agents/claude-code-skills

Start implementation only after the plan file exists and the user has confirmed to proceed.

Apply the standard 5 implementation steps from SOP:

1. Update tools/cc-sdd/src/agents/registry.ts
2. Add tools/cc-sdd/templates/manifests/{agent-id}.json
3. Add tools/cc-sdd/templates/agents/{agent-id}/...
4. Convert YAML frontmatter to target-agent format (keep body unless incompatibility is confirmed)
5. Add tools/cc-sdd/test/realManifest{AgentName}.test.ts

For skills integration, generate SKILL.md-based command packages under templates/agents/{agent-id}/skills/.

4) Handle Migration Cases

If the request is migration (or migration may be needed), read references/skills-migration.md and decide strategy before editing:

• Recommended default: additive migration ({agent-id}-skills as a new option)
• Use in-place replacement only when explicitly requested

Always document compatibility impact and CLI flag impact in the plan.

5) Verify Before Reporting

Run verification in tools/cc-sdd:

• npm test
• npm run build && node dist/index.js --agent {agent-id} --dry-run
• local temp-directory apply test with --overwrite=force
• language checks (--lang ja, --lang en)
• generated file count checks

If tests cannot run, explicitly report which step is blocked and why.

Completion Criteria

• Plan file exists at docs/cc-sdd/plans/agent-plan-{agent-id}.md
• Registry entry exists and routes to the new manifest id
• Manifest artifacts match target integration scope
• Templates render to expected target directories
• Real manifest test exists and passes
• Dry-run output matches expected artifact plan
• Plan document is updated with research evidence and verification notes
