What it does

Subagent Driven Development is an agent skill from Tai609/NebulaMat. Use when executing implementation plans with independent tasks — via fresh subagents (default), or sequential execution when subagents are unavailable or running in a separate session

Its SKILL.md is about 5.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including scripts (for example `implementer-prompt.md`, `re-review-prompt.md` and `task-reviewer-prompt.md`).

It sits in Agent Workflows, covering Subagents and Planning. The repository describes itself as: NebulaMat scientific materials research workbench.

When your agent uses it

Executing implementation plans with independent tasks — via fresh subagents (default)
Sequential execution when subagents are unavailable
Running in a separate session

Example prompts

“/subagent-driven-development”

Workflow steps

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

Dispatch the implementer
Handle the report
Review the task
The fix loop
Complete the task

What it can do on your machine

Read from SKILL.md and the folder at commit c906ed5. 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
Ships 3 files in scripts/, which the agent can run.
Shell commands in SKILL.md call:
- git
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, 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

Subagent Driven Development loads about 5.9k tokens when it runs. Until then it costs about 53 tokens; SKILL.md has 3,314 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~53
When it runs · the whole SKILL.md, loaded when a task matches: ~5.9k

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); the scripts in this folder are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 3,314 words (~5,916 tokens).

“Execute plan by dispatching a fresh implementer subagent per task, a task review (spec compliance + code quality) after each, and a broad whole-branch review at the end.”

Questions about Subagent Driven Development

What does Subagent Driven Development do?

When should I use Subagent Driven Development?

Subagent Driven Development fits situations like: executing implementation plans with independent tasks — via fresh subagents (default); sequential execution when subagents are unavailable; running in a separate session.

How do I install Subagent Driven Development in Claude Code?

Run `npx skills add Tai609/NebulaMat --skill subagent-driven-development -a claude-code`. Or copy the skill folder (runtime/skills-bundle/subagent-driven-development in Tai609/NebulaMat) into .claude/skills/subagent-driven-development in your project. Claude Code loads it when a task matches its description.

How do I install Subagent Driven Development in Codex?

Run `npx skills add Tai609/NebulaMat --skill subagent-driven-development -a codex`. Or copy the skill folder (runtime/skills-bundle/subagent-driven-development in Tai609/NebulaMat) into .agents/skills/subagent-driven-development in your project. Codex loads it when a task matches its description.

Can I use Subagent Driven Development in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Tai609/NebulaMat --skill subagent-driven-development -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/subagent-driven-development, .gemini/skills/subagent-driven-development, .github/skills/subagent-driven-development and .opencode/skills/subagent-driven-development in your project.

What does Subagent Driven Development need to run?

Going by SKILL.md and its folder, Subagent Driven Development needs the command-line tools its instructions call (git).

Does Subagent Driven Development access the network?

SKILL.md contains no URLs. Its commands use git, which can reach the network depending on how they are called. This is read from the text; nothing was executed.

Is Subagent Driven Development safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.

What licence does Subagent Driven Development use?

Subagent Driven Development has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.

How many tokens does Subagent Driven Development use?

About 5.9k tokens (SKILL.md is roughly 24k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Subagent Driven Development?

Skills that share tags, products or a category with Subagent Driven Development: Subagent Driven Development (Asvarox/allkaraoke, 261 stars), Executing Plans (GanyuanRan/Aegis, 1.3k stars), Exec (umputun/cc-thingz, 483 stars) and Autopilot End-to-End Builder (nick-vels/skills, 403 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Subagent Driven Development?

Tai609 (a GitHub user) maintains it in Tai609/NebulaMat, which has 100 GitHub stars. The repository holds 35 skills in this directory. The repository was last updated on September 6, 2026.
