# Module Setup

## Overview

Installs and configures a BMad module into a project. Module identity (name, code, version) comes from `assets/module.yaml`. Collects user preferences and writes them to three files:

- **`{project-root}/_bmad/config.yaml`** — shared project config: core settings at root (e.g. `output_folder`, `document_output_language`) plus a section per module with metadata and module-specific values. User-only keys (`user_name`, `communication_language`) are **never** written here.
- **`{project-root}/_bmad/config.user.yaml`** — personal settings intended to be gitignored: `user_name`, `communication_language`, and any module variable marked `user_setting: true` in `assets/module.yaml`. These values live exclusively here.
- **`{project-root}/_bmad/module-help.csv`** — registers module capabilities for the help system.

Both config scripts use an anti-zombie pattern — existing entries for this module are removed before writing fresh ones, so stale values never persist.

`{project-root}` is a **literal token** in config values — never substitute it with an actual path. It signals to the consuming LLM that the value is relative to the project root, not the skill root.

## On Activation

1. Read `assets/module.yaml` for module metadata and variable definitions (the `code` field is the module identifier)
2. Check if `{project-root}/_bmad/config.yaml` exists — if a section matching the module's code is already present, inform the user this is an update
3. Check for per-module configuration at `{project-root}/_bmad/prj/config.yaml` and `{project-root}/_bmad/core/config.yaml`. If either file exists:
   - If `{project-root}/_bmad/config.yaml` does **not** yet have a section for this module: this is a **fresh install**. Inform the user that installer config was detected and values will be consolidated into the new format.
   - If `{project-root}/_bmad/config.yaml` **already** has a section for this module: this is a **legacy migration**. Inform the user that legacy per-module config was found alongside existing config, and legacy values will be used as fallback defaults.
   - In both cases, per-module config files and directories will be cleaned up after setup.

If the user provides arguments (e.g. `accept all defaults`, `--headless`, or inline values like `user name is BMad, I speak Swahili`), map any provided values to config keys, use defaults for the rest, and skip interactive prompting. Still display the full confirmation summary at the end.

## Collect Configuration

Ask the user for values. Show defaults in brackets. Present all values together so the user can respond once with only the values they want to change (e.g. "change language to Swahili, rest are fine"). Never tell the user to "press enter" or "leave blank" — in a chat interface they must type something to respond.

**Default priority** (highest wins): existing new config values > legacy config values > `assets/module.yaml` defaults. When legacy configs exist, read them and use matching values as defaults instead of `module.yaml` defaults. Only keys that match the current schema are carried forward — changed or removed keys are ignored.

**Core config** (only if no core keys exist yet): `user_name` (default: BMad), `communication_language` and `document_output_language` (default: English — ask as a single language question, both keys get the same answer), `output_folder` (default: `{project-root}/_bmad-output`). Of these, `user_name` and `communication_language` are written exclusively to `config.user.yaml`. The rest go to `config.yaml` at root and are shared across all modules.

**Module config**: Read each variable in `assets/module.yaml` that has a `prompt` field. Ask using that prompt with its default value (or legacy value if available).

## Write Files

Write a temp JSON file with the collected answers structured as `{"core": {...}, "module": {...}}` (omit `core` if it already exists). Then run both scripts — they can run in parallel since they write to different files:

```bash
python3 scripts/merge-config.py --config-path "{project-root}/_bmad/config.yaml" --user-config-path "{project-root}/_bmad/config.user.yaml" --module-yaml assets/module.yaml --answers {temp-file} --legacy-dir "{project-root}/_bmad"
python3 scripts/merge-help-csv.py --target "{project-root}/_bmad/module-help.csv" --source assets/module-help.csv --legacy-dir "{project-root}/_bmad" --module-code prj
```

Both scripts output JSON to stdout with results. If either exits non-zero, surface the error and stop. The scripts automatically read legacy config values as fallback defaults, then delete the legacy files after a successful merge. Check `legacy_configs_deleted` and `legacy_csvs_deleted` in the output to confirm cleanup.

Run `scripts/merge-config.py --help` or `scripts/merge-help-csv.py --help` for full usage.

## Create Output Directories

After writing config, create any output directories that were configured. For filesystem operations only (such as creating directories), resolve the `{project-root}` token to the actual project root and create each path-type value from `config.yaml` that does not yet exist — this includes `output_folder` and any module variable whose value starts with `{project-root}/`. The paths stored in the config files must continue to use the literal `{project-root}` token; only the directories on disk should use the resolved paths. Use `mkdir -p` or equivalent to create the full path.

## Cleanup Legacy Directories

After both merge scripts complete successfully, remove the installer's package directories. Skills and agents in these directories are already installed at `.claude/skills/` — the `{project-root}/_bmad/` directory should only contain config files.

```bash
python3 scripts/cleanup-legacy.py --bmad-dir "{project-root}/_bmad" --module-code prj --also-remove _config --skills-dir "{project-root}/.claude/skills"
```

The script verifies that every skill in the legacy directories exists at `.claude/skills/` before removing anything. Directories without skills (like `_config/`) are removed directly. If the script exits non-zero, surface the error and stop. Missing directories (already cleaned by a prior run) are not errors — the script is idempotent.

Check `directories_removed` and `files_removed_count` in the JSON output for the confirmation step. Run `scripts/cleanup-legacy.py --help` for full usage.

## PR Jangler Extensions

Beyond standard config + help-CSV writes, PR Jangler setup validates its external dependencies and initializes the persistent workflow tree. Run after the config merge succeeds. Each extension is best-effort with clear error surfaces: a failed check is reported but does not abort setup unless explicitly noted.

### 1. Validate external CLIs

Check `gh`, `op`, and `git` are on PATH:

```bash
python3 scripts/check-deps.py
```

Reports each tool's presence and version. If `gh` is present, also checks it's authenticated and warns if the active user does not match `prj_bot_user`. If `op` is present, checks the user is signed in. Failures are warnings, not blocking — the user may install/authenticate after setup.

### 2. Test SMTP creds

Send a one-time "PR Jangler online" email to `prj_email_to` using the configured SMTP host + port + 1Password creds. Confirms the daily-report path works before the first cron tick.

```bash
python3 scripts/smtp-test.py --config-path "{project-root}/_bmad/config.toml"
```

Reports send success/failure. SMTP failure is a warning, not blocking — the user may reconfigure and re-test.

### 3. Pre-create GitHub labels

The orchestrator's siblings apply labels at runtime; those labels must exist on `prj_repo` first. Read `assets/labels.txt` (one label per line, format: `name|color|description`) and create each label on the target repo:

```bash
python3 scripts/create-labels.py --repo "{prj_repo}" --labels assets/labels.txt
```

Idempotent: existing labels with matching names are skipped, not overwritten. Failure on a single label is logged but does not abort the batch.

### 4. Initialize workflow tree

Create the `_bmad-output/pr-workflow/` skeleton and the empty `state.json` so the orchestrator's first run does not have to bootstrap:

```bash
python3 scripts/init-workflow.py --project-root "{project-root}" --repo "{prj_repo}"
```

Creates: `_bmad-output/pr-workflow/{state.json, prs/, logs/, reports/, worktrees/}`. Skips files that already exist.

### 5. Print consent banner template

Read `assets/consent-banner.md` and print it to the user with a one-line note: "Post this as a pinned issue on `{prj_repo}` before the bot opens its first fix-PR. Skipping this is fine for a personal test repo but expected for any repo with outside contributors."

## Confirm

Use the script JSON output to display what was written — config values set (written to `config.yaml` at root for core, module section for module values), user settings written to `config.user.yaml` (`user_keys` in result), help entries added, fresh install vs update. If legacy files were deleted, mention the migration. If legacy directories were removed, report the count and list (e.g. "Cleaned up 106 installer package files from bmb/, core/, \_config/ — skills are installed at .claude/skills/"). Also report:

- External CLI check results (gh, op, git versions; auth status)
- SMTP test result (sent / failed)
- Label creation results (created / skipped-existing / failed)
- Workflow tree init result (created / already-exists)

Then display the `module_greeting` from `assets/module.yaml` to the user.

## Outcome

Once the user's `user_name` and `communication_language` are known (from collected input, arguments, or existing config), use them consistently for the remainder of the session: address the user by their configured name and communicate in their configured `communication_language`.
