Three-layer customization (skill defaults → team → user) for BMad agents
and any skill that opts in. Users edit `_bmad/custom/{skill-name}.yaml`
(team, committed) or `{skill-name}.user.yaml` (personal, gitignored);
customizations survive updates.
Resolver is a Python script using PEP 723 inline metadata, invoked via
`uv run` so deps auto-install into a cached isolated env on first call.
This aligns with Anthropic's Agent Skills spec and BMB conventions, and
keeps the dependency declared (scannable by pip-audit/Dependabot) rather
than vendored.
## Design choices
- **Agent identity is hardcoded** in SKILL.md (name, title, Overview prose)
so skills can be invoked reliably by role *or* default name. Brand
recognition is preserved; customization shapes behavior, not identity.
- **Luminary-anchored personas** (e.g. "Channels Martin Fowler's
pragmatism and Werner Vogels's cloud-scale realism") deliver ~55%
token savings per agent while preserving distinctive voice beats.
- **Universal per-field merge rules** with v6.1-compatible agent
semantics: metadata shallow-merge, persona replace, critical_actions
and memories append, menu merge-by-code, all else deep-merge.
- **Workflow customization** shares the same surface — `bmad-product-brief`
pilots `activation_steps_prepend`, `activation_steps_append`, and
`skill_end` hooks that any workflow-style skill can adopt.
## Infrastructure
- `_bmad/scripts/` houses shared Python scripts (resolver + future).
- `_bmad/custom/` is provisioned empty with a seeded `.gitignore` for
`*.user.yaml` on fresh installs.
- Installer filters ensure `scripts/`, `custom/`, and sidecar-generated
`memory/` directories are never treated as modules.
- Dead v6.1 code cleaned up: `_config/agents/` no longer created,
`metadata.capabilities` removed from schema and CSV manifest.
fs-extra routes all operations through graceful-fs, which globally
monkey-patches node:fs with a deferred retry queue. During multi-module
installs (~500+ file ops), retried unlink operations from one module's
remove phase can fire after the next module's copy phase has written
files, silently deleting them non-deterministically.
Replace fs-extra with a thin fs-native.js wrapper over node:fs/promises
and node:fs. All 21 consumers now use native APIs with no global
monkey-patching, eliminating the retry-queue race condition entirely.
Closes#1779
* refactor(installer): remove custom content installation feature
Remove the entire local filesystem custom content feature from the
installer to make way for marketplace-based plugin installation.
Deleted: custom-handler.js, custom-module-cache.js, custom-modules.js
Removed: --custom-content CLI flag, interactive custom content prompts,
custom module caching, manifest tracking, missing-source resolution,
and related test suites. Updated docs across all translations.
* fix: address review findings from Augment
Fix admonition syntax (remove accidental space in :::note) across 4
translated docs files, and update stale JSDoc on listAvailable().
* refactor(installer): restructure installer with clean separation of concerns
Move tools/cli/ to tools/installer/ with major structural cleanup:
- InstallPaths async factory for path resolution and directory creation
- Config value object (frozen) replaces mutable config bag
- ExistingInstall value object replaces stateful Detector class
- OfficialModules + CustomModules + ExternalModuleManager replace monolithic ModuleManager
- install() is prompt-free; all user interaction in ui.js
- Update state returned explicitly instead of mutating customConfig
- Delete dead code: dependency-resolver, _base-ide, IdeConfigManager,
platform-codes helpers, npx wrapper, xml-utils
- Flatten directory structure: custom/handler → custom-handler,
tools/cli/ → tools/installer/, lib/ directories removed
- Update all path references in package.json, tests, CI, and docs
* fix(installer): guard ExistingInstall.version and surface module.yaml errors
Guard ExistingInstall.version access with .installed check in
uninstall.js, ui.js, and installer.js to prevent throwing on
empty/partial _bmad dirs. Surface invalid module.yaml parse errors
as warnings instead of silently returning empty results.
