What it does

Cc Sdd New Agent is an agent skill from gotalab/cc-sdd. 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.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `agents/openai.yaml`, `references/plan-output-checklist.md` and `references/skills-migration.md`).

It sits in Business, Finance & HR, covering Operations and SOPs and Subagents. The repository describes itself as: Turn approved specs into long-running autonomous implementation. A minimal, adaptable SDD harness with Agent Skills for Claude Code, Codex, Cursor, Copilot, Windsurf, OpenCode… The licence is MIT.

Workflow steps

5 steps, taken from the step headings in SKILL.md.

Run Phase 1 Research
Create Plan Document
Choose Base Pattern and Implement
Handle Migration Cases
Verify Before Reporting

What it can do on your machine

Read from SKILL.md and the folder at commit e2a0c67. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- npm
- node
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Cc Sdd New Agent loads about 1.1k tokens when it runs, and up to ~2k if it reads all its reference files. Until then it costs about 69 tokens; SKILL.md has 471 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~69
When it runs · the whole SKILL.md, loaded when a task matches: ~1.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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:

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

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

Show full SKILL.md (157 more words)Show less

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
