Claude Delegate

When to Use

• You want to delegate a bounded coding task to a separate claude implementer (Claude Code) and then review its diff yourself.
• The user explicitly asked for delegation to this implementer.

You are the orchestrator. Delegate one bounded coding task to a separate implementer — a Claude
Code CLI session — then review what it produced and land it yourself. You write the brief and own the
judgment; the separate Claude session edits the working tree; you verify and commit.

This skill is not a signal for the current Claude to implement directly. Use it only after the human
explicitly asks for delegation to another Claude Code process or session.

When not to use this

• The human asked the current agent to implement the task directly.
• The task is small enough to do inline and the human did not request delegation.
• The claude CLI is missing or unauthenticated (claude auth status).
• The task needs a stronger host boundary than Claude Code's tool permissions and shell-only sandbox

provide. Use an isolated container or VM for that requirement.

Prerequisites

1. claude --version succeeds.
2. claude auth status reports an authenticated session. If the orchestrator cannot access

the credential store, report that boundary and use an approved isolated environment;
do not automatically disable or escalate its sandbox to retrieve credentials.

1. The target repository is the directory passed with --cd.
2. On Linux/WSL2, Claude's sandbox dependencies are installed. The normal relay profile is

configured to fail when the sandbox is unavailable instead of silently running shell commands
unsandboxed. Existing merged settings can still affect the effective boundary.

The loop

1. Write the brief

The separate session has no orchestrator chat history. It receives the brief on stdin and can inspect
the target working tree.

Claude Code automatically discovers the target project's CLAUDE.md and normal local Claude
configuration because the relay does not use --bare. It does not generically auto-load
AGENTS.md. Read AGENTS.md yourself and copy every load-bearing constraint and the real gate
commands into the brief. Tell the implementer not to commit. Keep one task per brief.

Template and details: references/writing-the-brief.md.

2. Dispatch

This distribution is documentation-only: scripts/relay.mjs is absent. The commands below
require a separately obtained, pinned and reviewed upstream runtime. Do not claim these
profiles are enforced by the installed documentation or run a missing local path.

node "<skill-dir>/scripts/relay.mjs" --brief brief.txt --cd /path/to/repo
# review/diagnosis only:                 add --read-only
# continue the latest session:           add --resume-last
# continue the recorded session:         add --session <id>
# choose limits:                         add --max-turns 40 --max-budget-usd 10
# hard relay deadline:                   add --timeout 2h
# inspect every option:                  node .../relay.mjs --help

<skill-dir> is this installed skill directory, the folder containing this SKILL.md.

The relay runs claude -p --output-format stream-json --verbose, sends the brief through stdin, and
writes artifacts under the system temp directory by default. It never uses --bg or --bare, and it
never commits. See references/dispatch-and-poll.md.

3. Wait

The relay blocks until Claude exits. Use the orchestrator's background-command facility, or run it in
the foreground and wait. Completion means the process exited and result.json exists.

• A pre-run usage error exits 2 and writes no result.json.
• A missing claude exits 127 and writes status: "claude_unavailable".
• Timeout and caught relay signals terminate the whole implementer process tree and preserve an

outcome artifact.

Read finalMessage, touchedFiles, resultSubtype, and the raw artifact paths from result.json.

4. Review

Treat the implementer's report and gate outcomes as claims:

• Review edits to existing tests before a green gate means anything.
• Re-run the project's actual gates yourself.
• Read the complete diff against the brief, starting with touchedFiles.
• Inspect untracked and staged content as well as the ordinary diff.
• Run relevant guard skills if installed.

Full checklist: references/review-and-land.md.

5. Land

The orchestrator commits only after the gates pass and the diff holds. For rework, resume the same
Claude session with a delta brief:

echo "Keep the implementation, replace the mocked DB test with the migrated fixture, and remove the
unused import." | node "<skill-dir>/scripts/relay.mjs" --session <id> --cd /path/to/repo

Review a resumed run exactly like the first run.

Permission profiles

The normal profile is deliberately explicit:

• acceptEdits permission mode.
• Built-in tools restricted to Read, Glob, Grep, Edit, Write, and the platform shell.
• On macOS, Linux, and WSL2, Claude's shell sandbox is enabled with startup failure on missing

dependencies and no unsandboxed retry. Commands that stay sandboxed are auto-approved so ordinary
gates can run headlessly. The sandbox governs shell processes and their children only; merged
local or managed sandbox settings can add effective paths or exclusions.

• Configured MCP discovery and Claude.ai connectors are disabled, all MCP tools are denied, and

skills, commands, and Claude's Agent tool are unavailable to the child. Project CLAUDE.md, hooks,
normal authentication, session persistence, and other local settings still load.

• String rules deny common direct shell forms of git commit, git push, and nested claude, plus

any command containing claude-delegate. Aliases, scripts, and wrappers can bypass them, so they
are only a speed bump; the brief's no-commit instruction and orchestrator review remain the boundary.

Native Windows does not support Claude's shell sandbox. The relay restricts the tool surface and
pre-approves PowerShell so the run remains non-interactive, but that shell is not OS-isolated. Native
claude.exe and npm claude.cmd launch paths are implemented; Windows verification is pending.

--read-only uses plan mode with only Read, Glob, and Grep. It removes edit, write, and shell paths,
then compares parsed git porcelain and fingerprints the working-tree identity and index entries of
Git-visible paths that were already dirty.
readOnlyViolation is true when either signal proves a change, false when coverage is complete and
detects none, and null when coverage is incomplete. This is a reporting tripwire, not an OS boundary:
ignored paths and perfect restores are outside it, local hooks can write, and concurrent changes cannot
be attributed to Claude.

--dangerously-skip-permissions is an explicit opt-in to Claude's bypassPermissions mode. The
restricted tool surface, direct commit/push deny rules, and supported-platform shell sandbox remain,
but direct file tools can cross normal permission boundaries. Use it only with the human's explicit
acceptance.

Complementary to native Claude features

Claude subagents, agent teams, and background sessions are useful when the current Claude environment
is already the orchestrator and native coordination is the goal. This skill is complementary: it
provides a cross-orchestrator contract — self-contained brief → dispatch → artifacts → review → land
— and keeps the commit with the orchestrator.

Limitations

• Docs-only import — executable scripts/relay.mjs not included; see upstream for full runtime. Requires claude CLI, Node 18+, git.
• Relay never commits — it only returns structured result JSON; you review and land the commit.
