Cline Delegate

Cline Delegate

When to Use

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

You are the orchestrator. Delegate a bounded coding task to a separate implementer - the Cline coding agent CLI - then review what it produced and land it yourself. You write the brief and own the judgment; the implementer makes changes in its own session in a clean working tree; 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.
• The cline CLI is not installed or authenticated.
• You require the relay to configure a sandbox. Cline exposes sandbox controls, but this relay leaves them to the CLI environment; use --plan when the run must be read-only.

Prerequisites (check once)

1. Install cline (npm or bundled binary; the relay probes cline --version).
2. Authenticate: run cline auth (interactive sign-in), or configure ANTHROPIC_API_KEY / an OpenAI-compatible base URL.
3. Confirm cline --version succeeds.
4. Work in, or point --cd at, the target git repository.

Choose the model (optional)

Cline picks a default model. To choose another, pass the separate --model <id> or --provider <name> (e.g. anthropic, openai-native, openrouter). The relay accepts letters, digits, and . _ : / - only (the value reaches a shell on Windows).

The loop

Run these five steps per task. Steps 1, 4, and 5 require judgment; 2 and 3 are mechanical.

1. Write a brief

Cline sees only the text you send. It cannot read your conversation: the brief must stand alone with the goal, current state, what to change, what to leave untouched, the project's real gates, and a report contract. Keep each brief to a single task. Write it to a file and pass it as the relay's --brief. See references/writing-the-brief.md.

2. Dispatch

Use the bundled relay. It runs cline --json -v, streams the brief on stdin behind a fixed positional instruction, captures the JSON event stream, and writes result.json.

node "<skill-dir>/scripts/relay.mjs" --brief brief.txt --cd /path/to/repo
# choose a model / provider:        add --model <id>  --provider <name>
# read-only planning pass:          add --plan   (forces --auto-approve false)
# deny approval-required tools:     add --auto-approve false
# hard time limit (watchdog):        add --timeout 2h   (the 30m default suits brief runs; most implementation briefs should be 1-2h)
# see all options:                   node .../relay.mjs --help

The child'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

The relay blocks until cline 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 cline exits 127 and writes status: "cline_unavailable".

Completion means the process exited and result.json exists - trust process state and the working tree, not the progress display. Cline's final message is the finalMessage field of result.json.

4. Review - do not trust the self-report

• Re-run the project's gates yourself.
• Read the diff against the brief, starting with touchedFiles.
• Run relevant guard skills if installed.

See references/review-and-land.md.

5. Land it

If the work is good, commit it. The relay never commits - the diff and result.json are the record; run git status and git diff first to confirm exactly what changed. If the group has a PR flow, make the commit and push a branch; let human review happen. If the diff is wrong or incomplete, re-dispatch a corrected brief in a fresh run and review again.

Autonomy and permissions

The relay explicitly passes Cline's --auto-approve, defaulting to true in act mode. Cline plan mode can request a switch to act mode, so --plan forces --auto-approve false; the relay rejects --plan --auto-approve true. That pair is the read-only gate. Cline also exposes sandbox through --data-dir / CLINE_SANDBOX, but the relay does not configure or override it. Plan-first for anything risky, then review the plan before a separate act-mode dispatch. Malformed or malicious briefs remain dangerous in act mode because commands run as the current user.

Authorization model

Delegation is something the human opts into. Once briefed, cline works as a tool you approved use of. The boundary is: do not accept conclusions from the self-report; verify everything on disk. For anything touching credentials, production data, or irreversible operations, stop and ask the human first instead of encoding it in a brief.

Limitations

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