msd-core/get-shit-done/workflows/settings.md

<purpose>
Interactive configuration of GSD workflow agents (research, plan_check, verifier) and model profile selection via multi-question prompt. Updates .planning/config.json with user preferences. Optionally saves settings as global defaults (~/.gsd/defaults.json) for future projects.
</purpose>

<required_reading>
Read all files referenced by the invoking prompt's execution_context before starting.
</required_reading>

<process>

<step name="ensure_and_load_config">
Ensure config exists and load current state:

```bash
gsd-sdk query config-ensure-section
GSD_CONFIG_PATH=$(node "$HOME/.claude/get-shit-done/bin/gsd-tools.cjs" config-path)
INIT=$(gsd-sdk query state.load)
if [[ "$INIT" == @file:* ]]; then INIT=$(cat "${INIT#@file:}"); fi
```

Creates config.json (at the workstream-aware path) with defaults if missing and loads current config values.
Store `$GSD_CONFIG_PATH` — all subsequent reads and writes use this path, not the hardcoded `.planning/config.json`, so active-workstream installs write to the correct location (#2282).
</step>

<step name="read_current">
```bash
cat "$GSD_CONFIG_PATH"
```

Parse current values (default to `true` if not present):
- `workflow.research` — spawn researcher during plan-phase
- `workflow.plan_check` — spawn plan checker during plan-phase
- `workflow.verifier` — spawn verifier during execute-phase
- `workflow.nyquist_validation` — validation architecture research during plan-phase (default: true if absent)
- `workflow.ui_phase` — generate UI-SPEC.md design contracts for frontend phases (default: true if absent)
- `workflow.ui_safety_gate` — prompt to run /gsd-ui-phase before planning frontend phases (default: true if absent)
- `workflow.ai_integration_phase` — framework selection + eval strategy for AI phases (default: true if absent)
- `model_profile` — which model each agent uses (default: `balanced`)
- `git.branching_strategy` — branching approach (default: `"none"`)
- `workflow.use_worktrees` — whether parallel executor agents run in worktree isolation (default: `true`)
</step>

<step name="present_settings">

**Text mode (`workflow.text_mode: true` in config or `--text` flag):** Set `TEXT_MODE=true` if `--text` is present in `$ARGUMENTS` OR `text_mode` from init JSON is `true`. When TEXT_MODE is active, replace every `AskUserQuestion` call with a plain-text numbered list and ask the user to type their choice number. This is required for non-Claude runtimes (OpenAI Codex, Gemini CLI, etc.) where `AskUserQuestion` is not available.
Use AskUserQuestion with current values pre-selected:

</step>

<step name="update_config">
Merge new settings into existing config.json:

```json
{
  ...existing_config,
  "model_profile": "quality" | "balanced" | "budget" | "adaptive" | "inherit",
  "workflow": {
    "research": true/false,
    "plan_check": true/false,
    "verifier": true/false,
    "auto_advance": true/false,
    "nyquist_validation": true/false,
    "ui_phase": true/false,
    "ui_safety_gate": true/false,
    "ai_integration_phase": true/false,
    "text_mode": true/false,
    "research_before_questions": true/false,
    "discuss_mode": "discuss" | "assumptions",
    "skip_discuss": true/false,
    "use_worktrees": true/false
  },
  "git": {
    "branching_strategy": "none" | "phase" | "milestone",
    "quick_branch_template": <string|null>
  },
  "hooks": {
    "context_warnings": true/false,
    "workflow_guard": true/false
  }
}
```

Write updated config to `$GSD_CONFIG_PATH` (the workstream-aware path resolved in `ensure_and_load_config`). Never hardcode `.planning/config.json` — workstream installs route to `.planning/workstreams/<slug>/config.json`.
</step>

<step name="save_as_defaults">
Ask whether to save these settings as global defaults for future projects:

```
AskUserQuestion([
  {
    question: "Save these as default settings for all new projects?",
    header: "Defaults",
    multiSelect: false,
    options: [
      { label: "Yes", description: "New projects start with these settings (saved to ~/.gsd/defaults.json)" },
      { label: "No", description: "Only apply to this project" }
    ]
  }
])
```

If "Yes": write the same config object (minus project-specific fields like `brave_search`) to `~/.gsd/defaults.json`:

```bash
mkdir -p ~/.gsd
```

Write `~/.gsd/defaults.json` with:
```json

These settings apply to future /gsd-plan-phase and /gsd-execute-phase runs.

Quick commands:
- /gsd-set-profile <profile> — switch model profile
- /gsd-plan-phase --research — force research
- /gsd-plan-phase --skip-research — skip research
- /gsd-plan-phase --skip-verify — skip plan check
```
