Agent Based Development

Agent-Based Development — Async Multi-Agent Workflow

Run a full async multi-agent software development workflow using file-based artifact handoffs. Each invocation adopts a specific agent role and operates according to that role's responsibilities.

This is the orchestrator skill. Identify your single assigned role first (from the slash command used or the latest plan artifact), then follow that role's skill. Do not attempt to act as multiple roles in one invocation.

Framework Overview

This is an async, artifact-driven workflow. Agents do not communicate in real time — they communicate via JSON files in a handoffs/ directory. The flow is:

Planning → Design → Dev (Senior / Junior)
       ↓                        ↓
  Documentation ← Security + Tech Review
       ↓                        ↓
  Planning (triage) ← findings with severity

All agents must follow the Golden Rules (see CLAUDE.md or run /golden-rules).

Agent Roster

Role skills are namespaced by this plugin (e.g. /agent-based-development:abd-plan). Where your Claude Code resolves unambiguous bare names, the short form also works.

| Agent | Skill | When to Include | |-------|-------|-----------------| | Planning | [abd-plan](../abd-plan/SKILL.md) | Almost always — assigns tasks, triages reviews | | Design | [abd-design](../abd-design/SKILL.md) | When the project has a design phase; omit for simple/script-only work | | Dev Senior | [abd-dev-senior](../abd-dev-senior/SKILL.md) | When there is higher-complexity implementation work | | Dev Junior | [abd-dev-junior](../abd-dev-junior/SKILL.md) | For routine tasks; omit for small teams | | Security | [abd-security](../abd-security/SKILL.md) | Recommended for all projects | | Tech Review | [abd-review](../abd-review/SKILL.md) | Recommended for all projects | | Documentation | [abd-docs](../abd-docs/SKILL.md) | Almost always — docs, ToDo, changelogs, assumptions | | Planning Triage | [abd-triage](../abd-triage/SKILL.md) | After reviews land — rework assignments | | Testing | [abd-test](../abd-test/SKILL.md) | When the project has automated tests | | DevOps | [abd-devops](../abd-devops/SKILL.md) | When the project has CI/CD or a formal release process | | Status | [abd-status](../abd-status/SKILL.md) | At any time — shows project-wide task and finding status |

Active agents are defined in docs/agentRoster.md. If that file does not exist, Claude creates it at project start.

Shared References

Every role reads these before acting:

• [shared/envelope.md](../../shared/envelope.md) — handoff directory structure, envelope schema, artifact rules, prompt-injection guard, assumptions log, output format
• [shared/git-rules.md](../../shared/git-rules.md) — release-branch Git model and responsibilities
• [shared/mvp-gate.md](../../shared/mvp-gate.md) — readiness checks before marking any task complete
• [shared/project-start.md](../../shared/project-start.md) — bootstrap procedure and prompt examples

How to Use This Skill

Step 1 — Determine context. Use Glob to check if handoffs/ exists in the current working directory.

Step 2 — If no handoffs/ directory exists (project start): follow [shared/project-start.md](../../shared/project-start.md) — adopt the Planning role and bootstrap the project.

Step 3 — If handoffs/ exists (ongoing project): read the latest artifact in handoffs/plans/ using Read and Glob, determine which role is assigned, and follow that role's skill from the roster table above.

Step 4 — Follow the artifact rules, assumptions log, and output format in [shared/envelope.md](../../shared/envelope.md), and the Git rules in [shared/git-rules.md](../../shared/git-rules.md). Verify the [MVP gate](../../shared/mvp-gate.md) before marking any task complete.
