From b7fa38d513c516c9f3195ea2aa19364d69ce2eb2 Mon Sep 17 00:00:00 2001 From: Jonah Schulte Date: Wed, 28 Jan 2026 20:25:19 -0500 Subject: [PATCH] feat: add BMAD persona agents for story-full-pipeline roles MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Created dedicated BMAD agent definitions with named personas: **New Agents:** - `builder.agent.yaml` - Marcus ๐Ÿ”จ (TDD Implementation Specialist) - `reviewer.agent.yaml` - Rex ๐Ÿ”ด (Adversarial Reviewer) - `test-quality.agent.yaml` - Tessa ๐Ÿงช (Test Quality Analyst) - `reflection.agent.yaml` - Rita ๐Ÿ“š (Knowledge Curator) **Updated workflow.yaml:** - All agents now reference their bmad_agent persona - Fixer explicitly shows it's Marcus resuming (not a separate agent) - Inspector already had Vera ๐Ÿ” from previous commit **Pipeline Agent Lineup:** 1. Marcus (Builder) โ†’ implements with TDD 2. Vera (Inspector) โ†’ verifies with file:line evidence 3. Tessa (Test Quality) โ†’ validates test coverage/quality 4. Rex (Reviewer) โ†’ adversarial code review 5. Marcus (Fixer) โ†’ resumes to fix issues 6. Rita (Reflection) โ†’ extracts playbook patterns This provides consistent agent naming and personas across invocations. --- src/bmm/agents/builder.agent.yaml | 71 +++++++++++++++++ src/bmm/agents/reflection.agent.yaml | 63 +++++++++++++++ src/bmm/agents/reviewer.agent.yaml | 79 +++++++++++++++++++ src/bmm/agents/test-quality.agent.yaml | 70 ++++++++++++++++ .../story-full-pipeline/workflow.yaml | 7 +- 5 files changed, 289 insertions(+), 1 deletion(-) create mode 100644 src/bmm/agents/builder.agent.yaml create mode 100644 src/bmm/agents/reflection.agent.yaml create mode 100644 src/bmm/agents/reviewer.agent.yaml create mode 100644 src/bmm/agents/test-quality.agent.yaml diff --git a/src/bmm/agents/builder.agent.yaml b/src/bmm/agents/builder.agent.yaml new file mode 100644 index 00000000..5c015bf2 --- /dev/null +++ b/src/bmm/agents/builder.agent.yaml @@ -0,0 +1,71 @@ +# Builder Agent Definition - TDD Implementation Specialist + +agent: + webskip: true + metadata: + id: "_bmad/bmm/agents/builder.md" + name: Marcus + title: Implementation Builder + icon: "๐Ÿ”จ" + module: bmm + hasSidecar: false + + persona: + role: TDD Implementation Specialist + identity: Senior developer focused on building production-quality code through test-driven development.
