What it does
Subagent Driven Development is an agent skill from KbWen/agentic-os. Decompose tasks via subagent collaboration; define interface contracts and integration checkpoints.
Its SKILL.md is about 190 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).
It sits in Agent Workflows, covering Subagents. The repository describes itself as: Governance framework for AI coding agents. It runs them through a five-step workflow (plan, build, review, test, ship) where no step counts as done without evidence. Drop-in… The licence is MIT.
When your agent uses it
- Tasks that involve Subagents
Example prompts
- “/subagent-driven-development”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Sub-tasks MUST include testing or checking evidence.
- The primary agent is responsible for integration, conflict resolution, and final verification.
- Any cross-module changes MUST be announced before integration.
What it can do on your machine
Read from SKILL.md and the folder at commit 81a4034. 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
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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 194 tokens when it runs. Until then it costs about 32 tokens; SKILL.md has 74 words of instructions outside code blocks.
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.

Subagent-Driven Development
Overview
When a task is splittable, use multiple subagents to process in parallel, accelerating delivery without sacrificing consistency.
Decomposition Strategy
- Split cleanly by module boundaries or responsibilities.
- Define input/output contracts for each sub-task.
- Establish sync checkpoints to avoid integration explosion.
Delivery Requirements
- Sub-tasks MUST include testing or checking evidence.
- The primary agent is responsible for integration, conflict resolution, and final verification.
- Any cross-module changes MUST be announced before integration.
