description: >-
Delegate a coding task to the Mistral Vibe CLI (vibe) as a background implementer, then review its
diff and land it yourself. Use this whenever the user wants to hand implementation work to Vibe —
phrasings like "have Vibe implement X", "delegate this to Vibe", "run it through Mistral Vibe", "use
vibe to implement/fix/refactor" — or wants to run a queue of coding tasks through Vibe while staying
the reviewer. DO NOT USE for tasks small enough to do inline, or when the user wants the code written
directly without delegating.

Vibe Delegate
You are the orchestrator. Hand a bounded coding task to a separate implementer — the Mistral
Vibe CLI (vibe) — then review what it produced and land it yourself. You write the brief and own
the judgment; Vibe does the typing in its own session; you verify and commit.
The loop needs only a shell command and file access, so any comparable orchestrator can drive it.
When NOT to use this
The task is small enough to do inline; delegation overhead is not worth it.
Configure your API key with vibe --setup, or set MISTRAL_API_KEY in the environment.
Confirm vibe --version succeeds.
Work in, or point --cd at, the target git repository.
The loop
Run these five steps per task. Steps 1, 4, and 5 require judgment; 2 and 3 are mechanical.
1. Write the brief
Vibe sees only the text you send plus what it can inspect in the workspace — no chat history or shared
context. Include the goal, current state, what to change, what to leave untouched, the project's
actual gates, and a report contract. Tell Vibe not to commit. Keep one task per brief. See
references/writing-the-brief.md.
Default mode cannot approve most shell commands headlessly, so the orchestrator runs the gates. Ask
Vibe to run them only when the human explicitly authorized --full-access.
2. Dispatch
For Codex orchestration of background work, install and configure the separate
codex-background support utility first. If its MCP tools or registry are missing, stop and
report the setup requirement; do not silently fall back to model-driven polling. Then invoke its
registered delegate_run MCP tool once in place of the shell example below.
Follow that skill for structured common arguments, unchanged provider flags and reattachment by
runId. Keep the request pending until completion, then continue this skill's review and landing
steps. Other orchestrators keep the shell workflow below.
Use the bundled helper. It wraps Vibe's headless --prompt mode, captures the structured event
stream, and writes result.json. (<skill-dir> is the installed folder containing this SKILL.md.)
node "<skill-dir>/scripts/relay.mjs" --brief brief.txt --cd /path/to/repo
# limit turns for cost control: add --max-turns <n>
# indicative price threshold/token cap: add --max-price <usd> --max-tokens <n>
# planning/read-only: add --plan-only
# unrestricted shell and tools: add --full-access (explicit authorization required)
# resume the most recent session: add --resume-last (delta brief only)
# resume a specific session: add --session <id> (delta brief only)
# see all options: node .../relay.mjs --help
The child process's cwd pins the workspace. The relay writes artifacts under the system temp dir by
default and never commits. See references/dispatch-and-poll.md.
3. Wait for completion
Codex using codex-background keeps the original MCP request pending: no model-driven sleep,
status or log polling. Use delegate_wait only to reattach after an interrupted request.
The helper blocks until Vibe finishes. Run it with the orchestrator's background-command facility, or
background it in the shell and poll for result.json. A pre-run usage error exits 2 and writes no
result; a missing vibe exits 127 and writes status: "vibe_unavailable".
The watchdog writes status: "timeout"; terminating the relay on POSIX writes status: "aborted"
after stopping Vibe's process tree.
Trust process state and the working tree over a progress display. Completion means the process exited
and result.json exists.
4. Review — do not trust the self-report
Treat Vibe's final message and gate claims as claims:
Re-run the project's gates yourself.
Read the diff against the brief, starting with touchedFiles.
Run relevant guard skills if installed.
Round-trip migrations and grep for dangling references after removals or renames.
The implementer edits the working tree; the orchestrator commits. Commit only after the gates pass
and the diff holds. If rework is needed, send a delta brief with --resume-last or --session <id>,
then review again.
Autonomy and permissions
In --prompt mode the relay always sets the agent profile explicitly:
Relay flag
What Vibe gets
Use when
(default)
--agent accept-edits
Normal implementation — built-in file edits are approved
--plan-only
--agent plan
Read-only review, exploration, or planning
--full-access
--agent auto-approve
Explicitly authorized runs that need arbitrary shell/tools
Default mode lets Vibe edit files inside the target worktree. Approval-gated shell commands,
including most project gates, are denied headlessly; the orchestrator runs the gates.
--full-access disables Vibe's tool approvals and permits arbitrary shell/tool execution under the
user account; use it only with explicit human authorization. Always inspect touchedFiles and the
diff after a run.
--trust is always passed to prevent interactive directory-trust prompts in headless runs. It is
not a sandbox and does not grant tool permissions.
Authorization model
Delegation is something the human opts into. Once they have ("run this queue", "proceed"), committing
verified, gate-passing work is the agreed contract. Two limits remain: surface, don't absorb
(report Vibe's design decisions, defensible-but-unasked turns, and non-blocking nitpicks) and stop
for scope changes (if correct completion needs going beyond the brief, ask instead of expanding the
mandate). See references/review-and-land.md.
references/multi-task-queues.md — sequential queues, constraint
carry-forward, progress tracking, and the final coherence pass.
