description

Interactive settings menu for nyann preferences. View current values in a table, then pick one setting to change at a time via AskUserQuestion. Re-runnable anytime — does not require a full setup wizard. TRIGGER when the user says "change nyann settings", "nyann preferences", "configure nyann settings", "update my preferences", "toggle triage", "disable sentinel", "enable session triage", "/nyann:settings", "show nyann settings", "nyann config". ALSO trigger on direct shortcut: "/nyann:settings <key> <value>" — skip the menu and write the value directly. Do NOT trigger on "/nyann:setup" — that is the first-run wizard. Do NOT trigger on "/nyann:check-prereqs" — that inspects host tools, not nyann config.

CRITICAL: This skill uses AskUserQuestion for every choice. NEVER ask the user questions as plain text.

Script paths: nyann is a Claude Code plugin. Plugin root is two levels above this SKILL.md (<plugin_root>/skills/settings/SKILL.md). All scripts live at <plugin_root>/bin/.

Step 0: Verify setup ran

Run bash <plugin_root>/bin/setup.sh --check --json. If status != "configured", hand off to the setup skill — settings edits a file that doesn't exist yet.

Step 1: Direct shortcut path

If the user typed /nyann:settings <key> <value> (or otherwise gave both a key and a value in natural language), skip the menu and run:

bash <plugin_root>/bin/settings.sh --set <key> <value>

Surface the one-line confirmation and stop. No further prompts.

Step 2: Show current preferences

Run bash <plugin_root>/bin/settings.sh --show and render the output as a markdown table:

| Setting                          | Value                       |
|----------------------------------|-----------------------------|
| Default profile                  | auto-detect                 |
| Branching strategy               | auto-detect                 |
| Commit format                    | conventional-commits        |
| GitHub CLI                       | enabled                     |
| Documentation storage            | local                       |
| Auto-sync team profiles          | off                         |
| Session triage                   | enabled                     |
| Guard severity (default)         | advisory                    |
| CI sentinel notifications        | enabled                     |
| Staleness alerts                 | enabled                     |
| Git identity                     | Name <email>                |

Step 3: Ask which setting to change

Call AskUserQuestion with options listing each setting. Add a final "Done — no changes" option:

AskUserQuestion caps the options array at 4 entries per question, so present the picker in two passes: first ask the user which group of settings to explore, then ask which specific setting in that group to change.

Pass 1 — group picker:

{
  "questions": [
    {
      "question": "Which group of settings would you like to change?",
      "header": "Group",
      "multiSelect": false,
      "options": [
        { "label": "Core (profile, branching, commits, GitHub CLI)", "description": "Day-to-day defaults" },
        { "label": "Documentation + team sync",                       "description": "Docs storage, auto-sync of team profile sources" },
        { "label": "Proactive features (triage, guards, notifications)", "description": "Awareness + monitoring toggles" },
        { "label": "Done — no changes",                                "description": "Exit without writing" }
      ]
    }
  ]
}

Pass 2 — based on the group, ask the specific setting:

Core group:

{
  "questions": [{
    "question": "Which core setting would you like to change?",
    "header": "Setting",
    "multiSelect": false,
    "options": [
      { "label": "Default profile",    "description": "Stack-aware preference for which profile to apply" },
      { "label": "Branching strategy", "description": "github-flow | gitflow | trunk-based | auto-detect" },
      { "label": "Commit format",      "description": "conventional-commits | custom" },
      { "label": "GitHub CLI",         "description": "enabled | disabled (branch protection, PR helpers)" }
    ]
  }]
}

Documentation + team sync group:

{
  "questions": [{
    "question": "Which documentation / team-sync setting?",
    "header": "Setting",
    "multiSelect": false,
    "options": [
      { "label": "Documentation storage",   "description": "local | obsidian | notion" },
      { "label": "Auto-sync team profiles", "description": "Auto-sync team profile sources during bootstrap" }
    ]
  }]
}

Proactive features group:

{
  "questions": [{
    "question": "Which proactive-feature toggle?",
    "header": "Setting",
    "multiSelect": false,
    "options": [
      { "label": "Session triage",                "description": "Quiet drift check on first message each session" },
      { "label": "Guard severity (default)",      "description": "advisory | confirm — pre-action guard severity floor" },
      { "label": "Notifications (sentinel/staleness)", "description": "In-session CI sentinel + doc staleness toggles" },
      { "label": "Notification delivery",         "description": "Send alerts to Slack/Discord/webhook/email" }
    ]
  }]
}

If the user picks Notifications (sentinel/staleness), ask which of the two in-session toggles to change (CI sentinel notifications | Staleness alerts), then go to Step 4 for that toggle.

If the user picks Notification delivery, run the delivery sub-flow (Step 3a) below instead of Step 4 — delivery channels are multi-field, not a single enum.

Step 3a: Notification delivery sub-flow

External delivery fans queued notifications out to Slack, Discord, a generic webhook, or email. First pick the channel:

{
  "questions": [{
    "question": "Which delivery channel?",
    "header": "Channel",
    "multiSelect": false,
    "options": [
      { "label": "Slack",   "description": "Incoming webhook ({text: ...})" },
      { "label": "Discord", "description": "Webhook ({content: ...})" },
      { "label": "Webhook", "description": "Generic endpoint — raw JSON POST" },
      { "label": "Email",   "description": "sendmail or an SMTP relay" }
    ]
  }]
}

Then, because delivery secrets must never live in preferences.json, ask for the name of an environment variable that holds the endpoint URL — never the URL itself. Tell the user to export NYANN_SLACK_WEBHOOK=https://... in their shell profile, then store only the name here. Set the channel with the direct --set calls (one per field):

• Slack: notifications.delivery.slack.webhook_url_env <ENV_NAME> then notifications.delivery.slack.enabled true
• Discord: notifications.delivery.discord.webhook_url_env <ENV_NAME> then notifications.delivery.discord.enabled true
• Webhook: notifications.delivery.webhook.url_env <ENV_NAME> then notifications.delivery.webhook.enabled true
• Email: notifications.delivery.email.to <addr>, notifications.delivery.email.from <addr>, optional notifications.delivery.email.smtp_env <ENV_NAME>, then notifications.delivery.email.enabled true

bin/settings.sh REFUSES any value that looks like a URL (http(s)://) for a delivery key and prints why — surface that error verbatim and re-ask for the env-var NAME. After writing, return to Step 6.

(If the user expressed interest in a specific setting in their initial message — e.g., "toggle triage" — go straight to that setting's value picker without showing the group menu.)

Step 4: Ask for the new value

Once the user picks a setting, call AskUserQuestion with the valid values for that setting (see bin/settings.sh for the enums). Example for Session triage:

{
  "questions": [
    {
      "question": "Enable session-start drift triage?",
      "header": "Session triage",
      "multiSelect": false,
      "options": [
        { "label": "Enabled (Recommended)", "description": "Quiet drift check on first message each session" },
        { "label": "Disabled",              "description": "Skip the check; rely on /nyann:doctor manually" }
      ]
    }
  ]
}

Step 5: Write the value

Map the picker choice to the --set <key> <value> invocation. Key/value table:

Setting	Key	Values
Default profile	default_profile	auto-detect or <profile-name>
Branching strategy	branching_strategy	auto-detect, github-flow, gitflow, trunk-based
Commit format	commit_format	conventional-commits, custom
GitHub CLI	gh_integration	true, false
Documentation storage	documentation_storage	local, obsidian, notion
Auto-sync team profiles	auto_sync_team_profiles	true, false
Session triage	session_triage	true, false
Guard severity (default)	guard_default_severity	advisory, confirm
CI sentinel	notifications.sentinel	true, false
Staleness alerts	notifications.staleness_alerts	true, false
Slack delivery on/off	notifications.delivery.slack.enabled	true, false
Slack endpoint env name	notifications.delivery.slack.webhook_url_env	env-var NAME (e.g. NYANN_SLACK_WEBHOOK)
Discord delivery on/off	notifications.delivery.discord.enabled	true, false
Discord endpoint env name	notifications.delivery.discord.webhook_url_env	env-var NAME
Webhook delivery on/off	notifications.delivery.webhook.enabled	true, false
Webhook endpoint env name	notifications.delivery.webhook.url_env	env-var NAME
Email delivery on/off	notifications.delivery.email.enabled	true, false
Email recipient	notifications.delivery.email.to	address
Email sender	notifications.delivery.email.from	address
Email SMTP relay env name	notifications.delivery.email.smtp_env	env-var NAME (optional; else sendmail)

Run:

bash <plugin_root>/bin/settings.sh --set <key> <value>

Step 6: Loop or exit

After the write succeeds, show the updated row and call AskUserQuestion once more: "Change another setting?" → If yes, jump to Step 3. If no, print a short confirmation and exit.

Notes

• The script validates every value against the schema; if it rejects, surface the error verbatim and re-ask the picker.
• This skill never modifies git_identity interactively — git identity is set once at setup time. Edit it via the direct shortcut: /nyann:settings git_identity.name "Foo Bar".
• For first-time users with no preferences.json, hand off to the setup skill instead of trying to construct the file from scratch.
• Delivery secrets are never stored. The notifications.delivery.* *_env keys hold only the NAME of an environment variable; nyann reads the actual URL/token from that env var at delivery time. bin/settings.sh rejects any literal http(s):// value for a delivery key — if it does, the user pasted a URL where an env-var name belongs. Setting any delivery key upgrades the file to schemaVersion 3.
