setup — Setup, Configuration & Preflight

Type: Adaptive. Conversational when creating config, silent when checking drift.

Inputs

• Access to the project repository (gh CLI)
• Optionally: existing .github/buehler.yaml

Checklist

You MUST create a task for each of these items and complete them in order:

1. Detect environment — auto-detect owner/repo from git remote (Step 1)
2. Check for existing config — branch to wizard or preflight path (Step 2)
3. Wizard OR preflight — create config interactively or check drift silently (Steps 3-4)
4. Run preflight — execute runner.sh, parse JSONL results (Step 5)
5. Remediate — fix what the model can fix, guide the human on the rest (Step 6)
6. Converge — re-run preflight to confirm all green (Step 7)

Process

Step 1: Detect Environment

Auto-detect owner/repo from git remote:

gh repo view --json owner,name --jq '.owner.login + "/" + .name'

Also detect the default branch:

git symbolic-ref refs/remotes/origin/HEAD 2>/dev/null | sed 's@^refs/remotes/origin/@@' || echo "main"

Step 2: Check for Existing Config

Check if .github/buehler.yaml exists:

• Exists → go to Step 4 (preflight path)
• Does not exist → go to Step 3 (wizard path)

Step 3: Conversational Wizard (No Config)

Present recommended defaults section by section. For each section, show the default and ask: "Looks good, or want to change anything?"

Section order:

1. Project identity

   project:
     owner: {detected}
     repo: {detected}
     base_branch: {detected}
   

2. Project board — create or reuse a GitHub Project board for visual tracking.

   • Ask: "What would you like to name your project board?" Default recommendation: the repo name.
   • Check if a board with that title already exists: gh project list --owner {owner} --format json
   • If exists: "Found existing board '{title}' (#{number}). Use this one?" — if yes, store and skip creation.
   • If not:
     • Create: gh project create --owner {owner} --title "{title}" --format json — extract number
     • Get the project's GraphQL node ID: gh project view {number} --owner {owner} --format json --jq '.id'
     • Get the repo's GraphQL node ID: gh api graphql -f query='{ repository(owner: "{owner}", name: "{repo}") { id } }' --jq '.data.repository.id'
     • Link to repo:

       mutation { linkProjectV2ToRepository(input: { projectId: "{project_node_id}", repositoryId: "{repo_node_id}" }) { clientMutationId } }
       

     • Store board_number and board_title in config
   • Determine owner type for URL: gh api users/{owner} --jq '.type' (returns "User" or "Organization")
   • Present Status field update guide first (workflows reference statuses that must exist before automations can be configured):

     "First, update the board's Status field options. Open this URL:" https://github.com/{users|orgs}/{owner}/projects/{number}/settings/fields

     Edit the Status field and ensure these options exist (rename or add as needed):

     • Ready
     • In Progress
     • In Review
     • Blocked
     • Done

     Let me know when you've updated the Status field.

   • Wait for user confirmation that the Status field is updated.
   • Then present workflow automation guide (now that the referenced statuses exist):

     "Now configure the board's automation. Open this URL:" https://github.com/{users|orgs}/{owner}/projects/{number}/settings/workflows

     Enable these workflows:

     1. Item added to project → Set status to "Ready"
     2. Item closed → Set status to "Done"
     3. Item reopened → Set status to "Ready"

     Also set the default view to Board layout grouped by Status.

     Let me know when you've done this.

   • Wait for user confirmation before proceeding.

3. Sizing buckets

   sizing:
     metric: tokens
     buckets:
       xs: { lower: 1000, upper: 10000, description: "Trivial change, single file" }
       s: { lower: 10000, upper: 50000, description: "Small feature, few files" }
       m: { lower: 50000, upper: 200000, description: "Moderate feature, multiple files" }
       l: { lower: 200000, upper: 500000, description: "Large feature, significant scope" }
       xl: { lower: 500000, upper: null, description: "Must be split" }
   

4. Wiki settings

   wiki:
     directory: .wiki
     auto_clone: true
   

5. Labels — show the full default taxonomy:

   • Priority: critical, high, medium, low
   • Meta: ignore, mustread
   • Size: xs, s, m, l, xl
   • Status: ready, in-progress, in-review, blocked, done
   • Type: story, task, bug (only if Issue Types unavailable)
   • Backlog: now, next, later, icebox
   • Severity: critical, major, minor, trivial
   • Ask: "Any custom labels to add?"

6. Approval gates — these control where buehler pauses to ask for your permission. Present as a checklist of plain-language descriptions (not raw YAML). Default is fully autonomous (no gates enabled):

   • Pause before dispatching agents — ask before spawning implementation agents (default: off)
   • Pause before merging PRs — ask before merging approved task PRs into the feature branch (default: off)
   • Pause before closing milestones — ask before closing the milestone during integrate (default: off)
   • Pause before updating wiki — ask before pushing changes to the project wiki (default: off)

   Ask: "These are all off by default, meaning buehler will run autonomously. Want to enable any of these checkpoints?"

   Map selections back to approval_gates keys in the generated YAML:

   approval_gates:
     before_dispatch: false      # "Pause before dispatching agents"
     before_merge: false         # "Pause before merging PRs"
     before_close_milestone: false  # "Pause before closing milestones"
     before_wiki_update: false   # "Pause before updating wiki"
   

7. Subagent permissions — buehler agents need shell access to run git, tests, and linting.

   Auto-detect the project's stack using the same heuristics as build command detection:

   • Always include: Bash(git:*), Bash(gh:*), Bash(gh issue *)
   • package.json exists → add Bash(npm:*), Bash(npx:*), Bash(node:*)
   • Cargo.toml exists → add Bash(cargo:*)
   • pyproject.toml exists → add Bash(python3:*), Bash(pytest:*), Bash(ruff:*)
   • go.mod exists → add Bash(go:*)
   • Makefile exists → add Bash(make:*)

   Present the proposed permissions:

   buehler agents need shell access to run git, tests, and linting in parallel.
   Based on your project, here are the permissions I'd add to .claude/settings.json:
   
     - Bash(git:*)
     - Bash(gh:*)
     - Bash(gh issue *)
     - Bash(npm:*)       <- detected from package.json
     - Bash(npx:*)
     - Bash(node:*)
   
   Looks good, or want to change anything?
   

   After confirmation, read .claude/settings.json if it exists, merge the new permissions into the permissions.allow array (preserving existing entries), and write it back using the Write tool.

8. CODEOWNERS — buehler requires human review approval before merging PRs (review.require_codeowners defaults to true). This means a CODEOWNERS file must exist.

   Check for existing CODEOWNERS in standard locations (CODEOWNERS, .github/CODEOWNERS, docs/CODEOWNERS):

   • If found: "Found CODEOWNERS at {path}. Using existing file."
   • If not found:
     • Detect the repo owner: gh api repos/{owner}/{repo} --jq '.owner.login'
     • Propose a default CODEOWNERS file at .github/CODEOWNERS:

       # Default: repo owner is responsible for all files
       * @{owner}
       

     • Ask: "Who should be listed as code owners? Default is @{owner} for all files. You can add team-specific rules later."
     • After confirmation, write .github/CODEOWNERS using the Write tool

   If the user explicitly opts out of CODEOWNERS, set review.require_codeowners: false in the config and warn: "Without CODEOWNERS, buehler may self-merge PRs without human review."

Remaining config sections (branches, worktrees, commands, epics, validation, review) use sensible defaults and can be customized by editing .github/buehler.yaml directly after setup completes.

After all sections are confirmed, write .github/buehler.yaml using the Write tool directly (do NOT run mkdir first — Write creates parent directories automatically, and a separate mkdir triggers an unnecessary permission prompt).

Step 4: Preflight Path (Config Exists)

Run preflight silently:

{PLUGIN_ROOT}/scripts/preflight-checks/runner.sh

Parse the JSONL output. Three outcomes:

• All pass (exit 0, no fail lines): Report "Everything's in sync." and stop.
• Drift found (exit 1, has fail lines): Present the drift report and offer two paths:
  • "Fix drift" → proceed to Step 6 (remediation)
  • "Edit config" → reopen the wizard (Step 3) for relevant sections, then re-run preflight
• Warnings only (exit 0, has warn lines): Report warnings for awareness, but do not block.

Step 5: Run Preflight

Run the full preflight suite:

{PLUGIN_ROOT}/scripts/preflight-checks/runner.sh

Parse each JSONL line. Present results grouped by category:

## Preflight Results

### Environment
- [pass] gh 2.45.0 authenticated as {user}
- [pass] Inside a git repository
- [pass] GitHub remote found

### Repository Capabilities
- [pass] Wiki is enabled
- [warn] Issue Types API not available — will use type: labels
- [pass] Sub-issues API available

### Configuration
- [pass] Config file found
- [pass] YAML syntax valid

### Labels
- [fail] Missing label: priority:critical
- [fail] Missing label: status:ready
- [pass] Label exists: size:m
{...}

### Wiki
- [pass] Wiki repo is cloneable
- [fail] Home.md does not exist
- [warn] _Meta-Template.md does not exist yet

If any failures, proceed to Step 6. If all pass, report success and stop.

Step 6: Remediate

Read each failed check's fix field. Decide per-check:

Model can execute directly:

• Missing labels → run the gh label create commands from the fix fields
• Missing Home.md → clone wiki, create Home.md with a landing page, commit and push
• Missing config → should not happen here (wizard creates it), but generate defaults if needed
• Deprecated merge key in config → suggest removing it: "The merge section is no longer used — merge strategy is now hardcoded. Remove the merge: block from your .github/buehler.yaml."
• Missing board → create the board and link it to the repo using the commands from the wizard Section 2
• Board not linked → run the linkProjectV2ToRepository GraphQL mutation
• Missing .wiki/ in .gitignore → append .wiki/ (or configured wiki.directory value) to .gitignore
• Missing subagent permissions → read .claude/settings.json, merge required Bash permissions into permissions.allow, write back
• Missing CODEOWNERS → create .github/CODEOWNERS with * @{owner} as default, confirm with user
• Missing stabilization ticket → run bash scripts/create-stabilization-ticket.sh --owner {owner} --repo {repo} --milestone-title '{title}' --milestone-number {number} for each flagged milestone

Needs human action:

• Wiki not enabled → tell the user: "Wiki is not enabled. Enable it in repo Settings > General > Features > Wiki. Let me know when it's done and I'll re-check."
• gh CLI not authenticated → tell the user: "Run gh auth login and let me know when done."
• No GitHub remote → tell the user: "Add a GitHub remote: git remote add origin https://github.com/{owner}/{repo}.git"
• Workflow automations not configured → present the project board settings URL and walk the user through enabling the three workflows (Item added → Ready, Item closed → Done, Item reopened → Ready)

After executing all model-fixable items and confirming human-fixable items, proceed to Step 7.

Step 7: Converge

Re-run the preflight to confirm all checks now pass:

{PLUGIN_ROOT}/scripts/preflight-checks/runner.sh

• All green: "buehler is fully configured. You're ready to go. Next step: describe what you want to build (routes to superpowers:brainstorming to create a PRD), or if you already have a PRD, run /structure to convert it into GitHub issues and a milestone."
• Still has failures: Report remaining issues. If they're human-fixable, wait. If model-fixable items failed, investigate and retry (max 3 attempts).

Important Rules

1. Never mutate in preflight scripts — only the model remediates, reading the fix suggestions
2. Idempotent — running init multiple times is safe and expected
3. Wizard is conversational — one section at a time, confirm before moving on
4. Config is the source of truth — preflight checks desired state against config, not hardcoded values
5. Labels use : delimiter — never /
6. All skill references use buehler:{skill} format
