Brian Madison 1f488c956a feat(skills): TOML-based agent customization with stdlib Python resolver
Re-applies PR #2282's three-layer customization model (skill defaults →
team → user) but swaps YAML for TOML and uv for stdlib tomllib. Users
no longer need uv, pip, or a virtualenv — plain python3 (3.11+) is
sufficient, since tomllib shipped in the standard library.

## Schema changes vs PR #2282

- Flat agent schema: fields live directly under [agent], no nested
  metadata/persona sub-tables. Easier to author, less indentation.
- Non-configurable identity: name and title are declared in
  customize.toml as source-of-truth metadata (for future skill-manifest
  generation) but SKILL.md ignores overrides there — identity is
  hardcoded to preserve brand recognition.
- role redefined: now describes what the skill does for the user
  within its module phase, not a restatement of the title.
- persistent_facts replaces the activation-time file-context load AND
  the old memories concept. Entries can be literal sentences or
  file: prefixed paths/globs; avoids collision with the upcoming
  runtime memory sidecar.
- activation_steps_prepend / activation_steps_append harmonized across
  agents and workflows (replaces agent-specific critical_actions).
- [workflow] namespace mirrors [agent] for workflow customization.
  Same four structural rules, same field vocabulary.

## Resolver (src/scripts/resolve_customization.py)

Four purely structural merge rules, zero field-name hardcoding:

  - Scalars: override wins
  - Tables: deep merge
  - Arrays of tables where every item has `code` or `id`: merge by
    that key (matching keys replace, new keys append)
  - Any other array: append

No removal mechanism — overrides cannot delete base items. Fork the
skill or override by code with a no-op value to suppress defaults.

## Agents ported (6)

All six BMad agents now ship customize.toml + rewritten SKILL.md:
analyst (Mary), tech-writer (Paige), pm (John), ux-designer (Sally),
architect (Winston), dev (Amelia). Each uses the same 8-step
activation template: resolve → execute prepend → adopt persona →
load persistent facts → load config → greet (with {agent.icon}) →
execute append → dispatch or present menu.

Step 8 supports fast-path invocation: "hey Mary, let's brainstorm"
dispatches the matching menu item directly after greeting, skipping
the menu render when intent is clear. Chat, clarifying questions,
and bmad-help remain available when nothing on the menu fits.

## Installer + tooling

- _bmad/scripts/ provisioned on install (copies src/scripts/)
- _bmad/custom/ seeded with .gitignore for *.user.toml on fresh install
- Non-module-dir filter extended to skip _memory, memory, docs,
  scripts, and custom when scanning for modules
- Dead _config/agents/ directory no longer created
- metadata.capabilities removed from agent-manifest.csv and schema
- eslint config extended to cover src/scripts/**
- validate-file-refs.js knows about custom/ as install-only

## Deferred for follow-up

- bmad-product-brief workflow port (the pilot that demonstrates
  [workflow] + on_complete)
- Translated docs (cs/fr/vi-vn/zh-cn) — regenerate from English

BMad CLI Tool

Installing external repo BMad official modules

For external official modules to be discoverable during install, ensure an entry for the external repo is added to external-official-modules.yaml.

For community modules - this will be handled in a different way. This file is only for registration of modules under the bmad-code-org.

Post-Install Notes

Modules can display setup guidance to users after configuration is collected during npx bmad-method install. Notes are defined in the module's own module.yaml — no changes to the installer are needed.

Simple Format

Always displayed after the module is configured:

post-install-notes: |
  Thank you for choosing the XYZ Cool Module
  For Support about this Module call 555-1212  

Conditional Format

Display different messages based on a config question's answer:

post-install-notes:
  config_key_name:
    value1: |
      Instructions for value1...      
    value2: |
      Instructions for value2...      

Values without an entry (e.g., none) display nothing. Multiple config keys can each have their own conditional notes.

Example: TEA Module

The TEA module uses the conditional format keyed on tea_browser_automation:

post-install-notes:
  tea_browser_automation:
    cli: |
      Playwright CLI Setup:
        npm install -g @playwright/cli@latest
        playwright-cli install --skills      
    mcp: |
      Playwright MCP Setup (two servers):
        1. playwright    — npx @playwright/mcp@latest
        2. playwright-test — npx playwright run-test-mcp-server      
    auto: |
      Playwright CLI Setup:
        ...
      Playwright MCP Setup (two servers):
        ...      

When a user selects auto, they see both CLI and MCP instructions. When they select none, nothing is shown.
