Add Agent

Agent name: $ARGUMENTS

Supported agents: claude, codex, gemini, opencode

Instructions

Step 0 — Check setup

Read ~/.code-reviewer/config.json. If it does not exist, tell the user:

"code-reviewer has not been set up yet. Run /code-reviewer:setup first." Then stop.

Step 1 — Verify the agent CLI is installed

Run a quick smoke test to confirm the CLI tool is available and working.

claude: Already running (you are Claude). Skip the smoke test — just add it.

codex:

echo "Say hello" | codex -a never exec -s read-only --ephemeral --color never -

gemini: Read ~/.code-reviewer/config.json to get gemini_model (default: gemini-2.5-flash), then run:

echo "Say hello" | gemini -p "" -m <model> -o text --approval-mode yolo

opencode:

printf 'Reply with exactly: HELLO\n' | timeout 30 opencode run --model openai/gpt-5.5 --format json | jq -r 'select(.type == "text") | .part.text'

opencode reads OPENAI_API_KEY from the environment. If the smoke test fails with an auth error, remind the user to either export OPENAI_API_KEY=sk-... in their shell rc or run opencode auth.

Step 2 — Handle smoke test result

Succeeded (exit 0, produced output): proceed to Step 3.

Failed / command not found: tell the user the CLI is not installed or not working. Install hints:

codex: npm install -g @openai/codex. Verify with codex --version.
gemini: npm install -g @anthropic-ai/gemini-cli. Verify with gemini --version.
opencode: install from https://opencode.ai or npm install -g opencode-ai, then verify with opencode --version and ensure OPENAI_API_KEY is exported.

Ask the user whether to add the agent anyway (they may plan to install it later) or cancel.

Step 3 — Add the agent

${CLAUDE_PLUGIN_ROOT}/scripts/agents.sh add $ARGUMENTS

Step 4 — Confirm

${CLAUDE_PLUGIN_ROOT}/scripts/agents.sh list
