Fleet law: canon #5 owns model policy; canon #6 owns launcher naming, registry override precedence, and skip-perms. This skill keeps invocation mechanics, examples, and troubleshooting.

Every project has launchers: {name}Claude, {name}Codex, {name}Cursor, {name}Gemini, {name}Kiro. The launcher handles EVERYTHING: cd to repo, MCP wiring, secrets, iTerm profile, badge. You NEVER need source ~/.zshrc && cd ~/Gits/X && claude -s. Just: brainlayerClaude -s.

UNIFIED FLAGS (same across ALL CLIs)

CRITICAL:

• -s = skip permissions. For Codex it is a compatibility no-op; golem-install validates approval_policy = "never" and sandbox_mode = "danger-full-access" in host config. Capital -S/--sonnet is a separate Claude-only model request and is refused for full panes.
• Model/session policy lives in canon #5. A bare Claude launch pins the current top Opus at 1M; a bare Codex launch pins the current top Sol. Explicit Codex -m and -E values pass through, including when supplied through cmux spawn_agent.
• -p is NOT for agent sessions or verification gates. Open scope: it may survive for non-agent scripted one-shots; confirm with Etan before using it in automation.
• Codex resume is fail-closed. -c requires at least one usable rollout for the launch cwd and skips malformed newer candidates; a fresh cwd with no usable rollout exits loudly. Bare resume picker mode is refused because the launcher cannot recover model/effort before the picker selects a session.
• Codex -p/--print cannot be combined with -c or explicit resume; that combination exits loudly instead of silently starting a fresh headless session. A resumed session restores its recorded model and effort; explicit -m and/or -E override the recovered field, and when both are explicit the launcher skips rollout-state recovery and lets Codex validate the requested session.
• -c on Cursor is a no-op (not supported yet)

LAUNCHER NAME PATTERN

{projectName}{CLI}

Examples:
  brainlayerClaude    brainlayerCodex    brainlayerCursor
  golemsClaude        golemsCodex        golemsCursor
  orcClaude           orcCodex           orcCursor
  6pmClaude           6pmCodex           6pmCursor
  dashboardClaude     dashboardCodex     dashboardCursor

The name is the project key from ~/.config/ralphtools/registry.json, lowercased.

Agent-style projects

Registry entries can include an agent field:

{
  "yash": {
    "path": "$HOME/Gits/golems",
    "agent": "yash",
    "clis": ["claude", "codex", "cursor", "gemini", "kiro"]
  }
}

Claude launchers pass this through as --agent <name>. Codex, Cursor, Gemini, and Kiro do not read Claude Agent SDK files directly, so repoGolem reads ~/.claude/agents/<name>.md and injects it as the launcher's initial prompt. It preserves the frontmatter initialPrompt block when present, strips the rest of the YAML metadata, then appends the Markdown body. This is intentional: yashCodex, yashCursor, yashGemini, and yashKiro should inherit the same agent protocol instead of acting like generic shells in the project directory.

Plain Codex worker mode

Agent-style *Codex launchers keep registry persona injection by default. Opt into a plain worker with the long-only --worker flag or GOLEM_ROLE=worker:

orcCodex --worker -s -w $HOME/Gits/orchestrator.wt/my-lane
GOLEM_ROLE=worker orcCodex -s -w $HOME/Gits/orchestrator.wt/my-lane

The generated *CodexWorker aliases remain compatible and select the same mode. Worker mode adds only a one-line role banner before an optional caller prompt; it does not inject registry agent front-matter or boot-store instructions. Short -w remains the worktree-path flag and always requires an absolute path.

WARNING — launcher names strip hyphens from repo names

repoGolem launcher names are generated from the registry key, not the raw repo folder name. If a repo name contains hyphens, the launcher drops them:

repo: skill-creator
wrong launcher guess: skill-creatorClaude
actual launcher:      skillcreatorClaude

This matters when another tool tries to build a launcher name from repo directly. Known live failure: mcp__cmuxlayer__spawn_agent({repo:"skill-creator", cli:"claude"}) guessed skill-creatorClaude, hit zsh: command not found, and left the agent stuck at booting.

Before relying on a generated launcher for a new repo, verify the real launcher first:

which skillcreatorClaude
which skillcreatorCodex
which skillcreatorCursor

If the launcher guess is wrong, use the verified repoGolem launcher manually until cmuxlayer normalizes repo -> launcher with the same hyphen-stripping rule.

KEY REGISTERED PROJECTS

brainlayer topology — bare-mirror-style hub, main lives elsewhere (2026-06-07 weave E12)

~/Gits/brainlayer is the repo HUB, not the canonical main checkout: main is checked out at ~/Gits/brainlayer-prod (the prod/deploy worktree), and feature branches live in worktrees under ~/Gits/brainlayer/.worktrees/. Two rules:

1. Briefs must PIN the exact worktree path (-w $HOME/Gits/brainlayer/.worktrees/<task>). A brief that just says "brainlayer" leaves the worker guessing among three checkouts — live failure: worker's git status failed despite .git existing because the brief never pinned a path (bl-orqi-codex#2).
2. Local merges fail there. Because main is held by brainlayer-prod, gh pr merge --delete-branch from any other checkout dies with 'main' is already used by worktree at '…/brainlayer-prod' — see /pr-loop "Worktree-Locked Local Merge" for the remote fallback.

USAGE PATTERNS

Interactive agent (most common)

brainlayerClaude -s          # Claude in brainlayer repo, skip-permissions
orcCodex -s                  # Codex in orchestrator repo, skip-permissions
golemsCursor -s              # Cursor in golems repo, skip-permissions

Continue/resume a session

brainlayerClaude -s -c       # Resume last Claude session in brainlayer
orcClaude --resume            # Session picker for orchestrator
brainlayerCodex -s -c         # Resume newest usable Codex rollout for this cwd
brainlayerCodex -s resume ID  # Resume an explicit Codex session UUID

Codex deliberately refuses bare resume picker mode, -c in a cwd with no usable rollout, and every resume combined with -p/--print. These are fail-closed continuity guards: use -c from the session's cwd or pass its UUID, and send any follow-up prompt after the interactive resume opens. The fresh-cwd -c failure says Cannot honor Codex resume: no rollout found for selector --last in ${CODEX_HOME:-$HOME/.codex}/sessions.; bare resume says Cannot honor Codex resume: no session id or --last selector was provided. If matching rollouts exist but none carries usable state, it says Cannot honor Codex resume: no usable model/effort state found for selector --last.

Launch in a worktree

# Create the worktree FIRST — bare names fail silently. IN-REPO convention (ratified 2026-08-09):
git -C ~/Gits/golems worktree add ~/Gits/golems/.worktrees/my-task -b feat/my-task origin/master
golemsCodex -s -w $HOME/Gits/golems/.worktrees/my-task
 
# (legacy sibling ~/Gits/<repo>.wt/ paths resolve read-only until 2026-09-30, then die)

The launcher consumes -w/--worktree, cds to the literal argument, and does not pass --worktree to the underlying CLI.

-w contract (gen-12 weave E16): the path must be a pre-created absolute worktree directory that already exists on disk. The launcher does NOT resolve bare names, create worktrees, or fall back to the main checkout.

WRONG: golemsCodex -s -w weave-edits-a
       → _golem_launch_codex:cd:22: no such file or directory: weave-edits-a
       → 120s boot-timeout waiting for a pane that never started (ea8514a2:[643])
RIGHT: git worktree add … then golemsCodex -s -w $HOME/Gits/golems/.worktrees/weave-edits-a

An absolute path that does not exist yet dies the same way, one step earlier: when the repo has a .mcp.json, the launcher copies it into the worktree before the cd (golem-dispatch.zsh:486), so a missing directory aborts at the cp and drops you back at the shell. The pane looks like it simply never booted — silent lane death (2026-08-09).

-w never creates — spawn_agent does. Use spawn_agent({repo, cli, worktree:true}) (or worktree:{name|path|branch|base}) to create/reuse the worktree at launch; -w is launch-in-an-already-existing-worktree only.

Alternative fix (not shipped here): teach the launcher to resolve/create worktree paths from bare names — until then, briefs must inline absolute verified paths.

Scripted one-shot (NOT agent sessions; scope under review)

brainlayerCursor -s -p "Audit all .py files for stubs"
# → runs cursor agent --yolo --approve-mcps --print --output-format text "prompt"

Do not use this form for workers, leads, or verification gates. Those are interactive repoGolem launcher sessions (brainlayerCursor -s, then send the prompt). Whether -p should remain for non-agent scripted one-shots is an open scope question for Etan; keep the flag documented, but do not apply it to agent sessions.

Model policy

orcClaude -s                              # Default: current top Opus at 1M
brainlayerClaude -s -m claude-opus-4-8   # Explicit non-Sonnet full pane
brainlayerClaude -s -S                    # Refused: Sonnet is headless/subagent-only
brainlayerClaude -s -p "one shot" -S     # Allowed headless Sonnet run
brainlayerCodex -s                        # Default: current top Sol
brainlayerCodex -s -m gpt-5.6-luna -E max # Explicit Codex model + effort

Launcher enforcement is defined by canon #5. Claude refuses Sonnet-tier models for full panes but accepts explicit non-Sonnet models. Codex passes explicit model and effort values through; its own runtime validates the requested model. -p remains scripted one-shot mode, not a worker/lead session or verification gate.

Via cmux (spawning from orchestrator)

spawn_agent({ repo: "brainlayer", cli: "codex", model: "gpt-5.6-luna", effort: "high", prompt: "Fix the FTS5 sync issue in search.py" })
→ returns agent_id
 
wait_for({ agent_id, target_state: "ready", timeout_ms: 120000 })
send_to_agent({ agent_id, text: "Keep the fix narrow and cite the changed file", press_enter: true })

cmuxlayer PR #396 is merged: an explicit Codex model is checked against codex debug models --bundled before a pane is created, then model and effort are passed to the repoGolem launcher as -m and -E. Omit model to use the launcher's bare top-Sol pin; include it when the mission requires a specific supported model. Unsupported models fail before surface creation; if cmuxlayer prepared a new worktree first, it rolls that worktree back. At read time spawn_agent.effort accepts medium, high, xhigh, and ultra; use the launcher directly for supported low or max.

NEVER do this:

# WRONG — raw CLI, no launcher
send_input(surface, "source ~/.zshrc && cd ~/Gits/brainlayer && codex --dangerously-bypass-approvals-and-sandbox")

WHAT LAUNCHERS HANDLE (so you don't have to)

1. cd to repo — changes to the correct directory
2. MCP wiring — builds .mcp.json from registry, merges with repo's .mcp.json
3. Secrets — sets up 1Password-backed env vars via ralph-secrets.zsh
4. iTerm profile — switches to "Golems" profile with correct font
5. Tab title + badge — sets emoji + project name (e.g., "🌔 golemsClaude")
6. BrainLayer project tag — worktree path becomes the project tag automatically (e.g., brainlayer-p0-hybrid → project:"brainlayer-p0-hybrid")

HOW TO ADD A NEW PROJECT

1. Edit ~/.config/ralphtools/registry.json:

"myproject": {
    "path": "$HOME/Gits/myproject",
    "displayName": "My Project",
    "mcps": [],
    "secrets": {},
    "created": "2026-04-05T00:00:00Z",
    "clis": ["claude", "codex", "cursor"]
}

1. Regenerate launchers:

_ralph_generate_launchers_from_registry
source ~/.config/ralphtools/launchers.zsh

1. Verify: which myprojectClaude should resolve.

HOW TO ADD A NEW CLI TO ALL PROJECTS

Example: adding cursor to all 27 projects (done April 4, 2026):

1. Edit registry.json — add "cursor" to each project's clis array
2. Regenerate: _ralph_generate_launchers_from_registry
3. Source: source ~/.config/ralphtools/launchers.zsh
4. Verify: which brainlayerCursor for a few projects

CRITICAL GOTCHAS

-s is a LAUNCHER flag, not a Claude CLI flag

-s only works with repoGolem launchers (brainlayerClaude -s). When using raw claude --agent, you MUST spell out --dangerously-skip-permissions. Evidence: claude --agent skill-creator -s failed; had to use claude --agent skill-creator --dangerously-skip-permissions.

Codex: bare pins Sol; explicit selections are first-class

Canon #5 owns the choice. Use the bare launcher when the current top Sol is intended; use -m/-E when the mission names a supported model or effort. cmux spawn_agent.model is equivalent for model selection, while its current effort enum is the four-value subset documented above. Verify effective values from Codex session metadata rather than the agent's self-description.

Cursor model: expect default/Auto

User complained when Cursor defaulted to a specific model instead of Auto. Don't override with --model for Cursor data-gathering tasks.

-p is NOT for agent sessions

For interactive agents (monitored via cmux), launch WITHOUT -p: brainlayerCursor -s. Then send prompt separately. This includes verification gates. -p remains documented only for possible non-agent scripted one-shots; that scope needs Etan confirmation before automation depends on it.
