common-subagent-driven-development SKILL.md skillA

This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.

common-subagent-driven-development from hoangnguyen0403/agent-skills-standard is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add hoangnguyen0403/agent-skills-standard/common-subagent-driven-development@git:20261030.a5465a6

Execute an approved implementation plan at the context boundary that preserves required independence and review. Use when implementing plans, executing multi-task PRs, choosing between main-loop and dispatched execution, or transitioning from planning to implementation.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Subagent-Driven Development (SDD)

## **Priority: P1 (HIGH)**

Execute a multi-task plan with one implementation owner per slice, independent review after each task, and whole-branch review before completion.

## 1. Placement Decision

Choose placement before any edit. Delegate only for a named benefit: independent parallel work over disjoint owned paths verifiable alone; measured context pressure; a required independent verification gate owned by someone other than the implementer; or host-enforced permission isolation, because prompt text is not enforcement. A specialist label, workflow stage, file count, plan length, or "more thorough" fan-out is not a named benefit. Precedence, first match wins: controlling host authority, then required independence or isolation, then coupling and verifiability, then economical eligible capability (`common-task-complexity-routing`).

| Condition | Placement |
| --- | --- |
| Coupled sequential reasoning; host permits main-loop implementation | One implementation context, skills loaded progressively |
| Independent, bounded, verifiable slices with disjoint ownership | Concurrent bounded workers, one owner per component |

How to install

The exact contents, by fingerprint
mdr add hoangnguyen0403/agent-skills-standard/common-subagent-driven-development@sha256:427916c5ad67235e

The line at the top of this page pins the label git:20261030.a5465a6, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
