* fix(build): use file glob instead of sidebar parsing for llms-full.txt

Replace brittle sidebar.js regex parsing with recursive file glob.
The old approach captured non-file strings like 'autogenerated' and
category labels, resulting in only 5 files being processed.

Now correctly processes all 86+ markdown files (~95k tokens).

* fix(seo): use absolute URLs in AI meta tags for agent discoverability

AI web-browsing agents couldn't follow relative paths in meta tags due to
URL security restrictions. Changed llms-full.txt and llms.txt meta tag
URLs from relative (baseUrl) to absolute (urlParts.origin + baseUrl).

* refactor(docs): recategorize misplaced files per Diataxis analysis

Phase 2.5 categorization fixes based on post-migration analysis:

Moved to correct Diataxis categories:
- tutorials/installation.md → deleted (duplicate of how-to/install-bmad.md)
- tutorials/brownfield-onboarding.md → how-to/brownfield/index.md
- reference/faq/* (8 files) → explanation/faq/
- reference/agents/barry-quick-flow.md → explanation/agents/
- reference/agents/bmgd-agents.md → explanation/game-dev/agents.md

Created:

* fix(css): use fixed width layout to prevent content shifting

Apply React Native docs approach: set both width and max-width at
largest breakpoint (1400px) so content area maintains consistent
size regardless of content length. Switches to fluid 100% below
1416px breakpoint.

Test Architect (TEA) Overview Understanding the Test Architect (TEA) agent and its role in BMad Method

The Test Architect (TEA) is a specialized agent focused on quality strategy, test automation, and release gates in BMad Method projects.

Overview

  • Persona: Murat, Master Test Architect and Quality Advisor focused on risk-based testing, fixture architecture, ATDD, and CI/CD governance.
  • Mission: Deliver actionable quality strategies, automation coverage, and gate decisions that scale with project complexity and compliance demands.
  • Use When: BMad Method or Enterprise track projects, integration risk is non-trivial, brownfield regression risk exists, or compliance/NFR evidence is required. (Quick Flow projects typically don't require TEA)

Choose Your TEA Engagement Model

BMad does not mandate TEA. There are five valid ways to use it (or skip it). Pick one intentionally.

  1. No TEA

    • Skip all TEA workflows. Use your existing team testing approach.
  2. TEA-only (Standalone)

    • Use TEA on a non-BMad project. Bring your own requirements, acceptance criteria, and environments.
    • Typical sequence: *test-design (system or epic) -> *atdd and/or *automate -> optional *test-review -> *trace for coverage and gate decisions.
    • Run *framework or *ci only if you want TEA to scaffold the harness or pipeline.
  3. Integrated: Greenfield - BMad Method (Simple/Standard Work)

    • Phase 3: system-level *test-design, then *framework and *ci.
    • Phase 4: per-epic *test-design, optional *atdd, then *automate and optional *test-review.
    • Gate (Phase 2): *trace.
  4. Integrated: Brownfield - BMad Method or Enterprise (Simple or Complex)

    • Phase 2: baseline *trace.
    • Phase 3: system-level *test-design, then *framework and *ci.
    • Phase 4: per-epic *test-design focused on regression and integration risks.
    • Gate (Phase 2): *trace; *nfr-assess (if not done earlier).
    • For brownfield BMad Method, follow the same flow with *nfr-assess optional.
  5. Integrated: Greenfield - Enterprise Method (Enterprise/Compliance Work)

    • Phase 2: *nfr-assess.
    • Phase 3: system-level *test-design, then *framework and *ci.
    • Phase 4: per-epic *test-design, plus *atdd/*automate/*test-review.
    • Gate (Phase 2): *trace; archive artifacts as needed.

If you are unsure, default to the integrated path for your track and adjust later.

Phase Numbering Note: BMad uses a 4-phase methodology with optional Phase 1 and documentation prerequisite:

  • Documentation (Optional for brownfield): Prerequisite using *document-project
  • Phase 1 (Optional): Discovery/Analysis (*brainstorm, *research, *product-brief)
  • Phase 2 (Required): Planning (*prd creates PRD with FRs/NFRs)
  • Phase 3 (Track-dependent): Solutioning (*architecture*test-design (system-level) → *create-epics-and-stories → TEA: *framework, *ci*implementation-readiness)
  • Phase 4 (Required): Implementation (*sprint-planning → per-epic: *test-design → per-story: dev workflows)

TEA workflows: *framework and *ci run once in Phase 3 after architecture. *test-design is dual-mode:

  • System-level (Phase 3): Run immediately after architecture/ADR drafting to produce test-design-system.md (testability review, ADR → test mapping, Architecturally Significant Requirements (ASRs), environment needs). Feeds the implementation-readiness gate.
  • Epic-level (Phase 4): Run per-epic to produce test-design-epic-N.md (risk, priorities, coverage plan).

Quick Flow track skips Phases 1 and 3. BMad Method and Enterprise use all phases based on project needs. When an ADR or architecture draft is produced, run *test-design in system-level mode before the implementation-readiness gate. This ensures the ADR has an attached testability review and ADR → test mapping. Keep the test-design updated if ADRs change.


Why TEA is Different from Other BMM Agents

TEA is the only BMM agent that operates in multiple phases (Phase 3 and Phase 4) and has its own knowledge base architecture.

Phase-Specific Agents (Standard Pattern)

Most BMM agents work in a single phase:

  • Phase 1 (Analysis): Analyst agent
  • Phase 2 (Planning): PM agent
  • Phase 3 (Solutioning): Architect agent
  • Phase 4 (Implementation): SM, DEV agents

TEA: Multi-Phase Quality Agent (Unique Pattern)

TEA is the only agent that operates in multiple phases:

Phase 1 (Analysis) → [TEA not typically used]
    ↓
Phase 2 (Planning) → [PM defines requirements - TEA not active]
    ↓
Phase 3 (Solutioning) → TEA: *framework, *ci (test infrastructure AFTER architecture)
    ↓
Phase 4 (Implementation) → TEA: *test-design (per epic: "how do I test THIS feature?")
                        → TEA: *atdd, *automate, *test-review, *trace (per story)
    ↓
Epic/Release Gate → TEA: *nfr-assess, *trace Phase 2 (release decision)

TEA's 8 Workflows Across Phases

Standard agents: 1-3 workflows per phase TEA: 8 workflows across Phase 3, Phase 4, and Release Gate

Phase TEA Workflows Frequency Purpose
Phase 2 (none) - Planning phase - PM defines requirements
Phase 3 *framework, *ci Once per project Setup test infrastructure AFTER architecture
Phase 4 *test-design, *atdd, *automate, *test-review, *trace Per epic/story Test planning per epic, then per-story testing
Release *nfr-assess, *trace (Phase 2: gate) Per epic/release Go/no-go decision

Note: *trace is a two-phase workflow: Phase 1 (traceability) + Phase 2 (gate decision). This reduces cognitive load while maintaining natural workflow.


TEA Command Catalog

Command Primary Outputs Notes
*framework Playwright/Cypress scaffold, .env.example, .nvmrc, sample specs Use when no production-ready harness exists
*ci CI workflow, selective test scripts, secrets checklist Platform-aware (GitHub Actions default)
*test-design Combined risk assessment, mitigation plan, and coverage strategy Risk scoring + optional exploratory mode
*atdd Failing acceptance tests + implementation checklist TDD red phase + optional recording mode
*automate Prioritized specs, fixtures, README/script updates, DoD summary Optional healing/recording, avoid duplicate coverage
*test-review Test quality review report with 0-100 score, violations, fixes Reviews tests against knowledge base patterns
*nfr-assess NFR assessment report with actions Focus on security/performance/reliability
*trace Phase 1: Coverage matrix, recommendations. Phase 2: Gate decision (PASS/CONCERNS/FAIL/WAIVED) Two-phase workflow: traceability + gate decision
