name: run-centaur-dev description: "Bring up the full Centaur development stack locally with cargo-run Rust API, Kind agent sandboxes, onepassword/iron-proxy credentials, Tailscale Funnel Slack webhooks, Slack app manifest setup, and centaur-session-cli smoke tests or thread attachment."

Run Centaur Dev

Use this when the user asks to run Centaur locally end-to-end with the Rust API, real agent sandboxes, Slackbot v2, Tailscale Funnel, or centaur-session-cli.

Ground Rules

  • Stay local. Do not SSH to the deploy box and do not touch production unless explicitly asked.
  • Use services/api-rs for the Rust control plane. The API should run on the host with cargo run; sandboxes run in Kind.
  • Prefer onepassword/iron-proxy for model/tool credentials. Do not pass real LLM keys into sandbox env unless the user explicitly asks for a shortcut.
  • Never print secret values. Use op read/op item get into env vars and only log which secret names were used.
  • Before branch changes or cleanup, check git status --short --branch and preserve unrelated dirty files.

Prereqs

Required CLIs: cargo, docker, kind, kubectl, just, bun, tailscale, op.

If 1Password is not signed in, run op signin. The usual vaults are centaur-agent for agent/iron-proxy credentials and prd-centaur-infra for deployed Slack app or infra references. Do not guess item paths; discover them:

op item list --vault centaur-agent | rg -i 'slack|openai|anthropic|amp|iron|broker'
op item list --vault prd-centaur-infra | rg -i 'slack|centaur'

1. Start Kind Agent Sandbox Infra

From repo root:

cd services/api-rs
just kind-e2e-up

This creates/uses kind-centaur-api-rs-e2e, installs the Agent Sandbox CRD/controller, and creates namespace centaur-sandbox-e2e.

Build the images the sandbox backend needs, then load them only if the Kind node does not already have them:

just kind-e2e-build-images
just kind-e2e-load-images

kind-e2e-load-images skips kind load when centaur-agent:latest and centaur-iron-proxy:latest are already present in the Kind node. Re-run with KIND_E2E_FORCE_IMAGE_LOAD=1 just kind-e2e-load-images only after changing the sandbox image, iron-proxy image, or baked sandbox skills/prompts. If you keep the Kind cluster around, the images stay around too; deleting the Kind cluster deletes that node-local image cache.

Bootstrap namespace secrets for the sandbox namespace. Set real values first; SLACKBOT_API_KEY can be a local random service key because api-rs currently has no auth middleware.

export OP_SERVICE_ACCOUNT_TOKEN="$(op read 'op://centaur-agent/<item>/<field>')"
export OP_VAULT=centaur-agent
export SLACK_BOT_TOKEN="$(op read 'op://<vault>/<slack-item>/<bot-token-field>')"
export SLACK_SIGNING_SECRET="$(op read 'op://<vault>/<slack-item>/<signing-secret-field>')"
export SLACKBOT_API_KEY="${SLACKBOT_API_KEY:-$(openssl rand -hex 32)}"

CENTAUR_NAMESPACE=centaur-sandbox-e2e just bootstrap-secrets

Verify:

kubectl --context kind-centaur-api-rs-e2e -n agent-sandbox-system rollout status deploy/agent-sandbox-controller --timeout=120s
kubectl --context kind-centaur-api-rs-e2e -n centaur-sandbox-e2e get secrets centaur-infra-env centaur-firewall-ca centaur-firewall-ca-key

2. Start Postgres

For host-run api-rs, use a host-reachable Postgres. A disposable local container is usually fastest:

docker rm -f centaur-api-rs-postgres 2>/dev/null || true
docker run --name centaur-api-rs-postgres \
  -e POSTGRES_USER=postgres \
  -e POSTGRES_PASSWORD=postgres \
  -e POSTGRES_DB=centaur \
  -p 5432:5432 \
  -d postgres:16

export DATABASE_URL=postgresql://postgres:postgres@127.0.0.1:5432/centaur

If port 5432 is occupied, map another host port and update DATABASE_URL.

3. Run api-rs On The Host

Pick the host URL that Kind pods can reach. On Docker Desktop this is usually host.docker.internal; on OrbStack it may be host.orb.internal.

export SANDBOX_HOST_API_URL=http://host.docker.internal:8080

Run the API:

cd services/api-rs
RUST_LOG=info \
DATABASE_URL="$DATABASE_URL" \
RUN_MIGRATIONS=true \
BIND_ADDR=0.0.0.0:8080 \
SESSION_SANDBOX_K8S_CONTEXT=kind-centaur-api-rs-e2e \
SESSION_SANDBOX_K8S_NAMESPACE=centaur-sandbox-e2e \
SESSION_SANDBOX_BACKEND=agent-k8s \
SESSION_SANDBOX_WORKLOAD=codex-app-server \
SESSION_SANDBOX_IMAGE=centaur-agent:latest \
SESSION_SANDBOX_IMAGE_PULL_POLICY=IfNotPresent \
KUBERNETES_SANDBOX_IRON_PROXY_MODE=enabled \
KUBERNETES_IRON_PROXY_IMAGE_PULL_POLICY=IfNotPresent \
KUBERNETES_FIREWALL_CA_SECRET_NAME=centaur-firewall-ca \
KUBERNETES_FIREWALL_CA_KEY_SECRET_NAME=centaur-firewall-ca-key \
FIREWALL_MANAGER_SECRET_SOURCE=onepassword \
KUBERNETES_BOOTSTRAP_SECRET_NAME=centaur-infra-env \
OP_VAULT="${OP_VAULT:-centaur-agent}" \
TOOL_DIRS="$PWD/../../tools" \
REPOS_PATH="$HOME/paradigmxyz" \
SESSION_SANDBOX_CENTAUR_API_URL="$SANDBOX_HOST_API_URL" \
CODEX_AUTH_MODE=api_key \
cargo run -p centaur-api-server

In another shell:

curl -sS http://127.0.0.1:8080/healthz
kubectl --context kind-centaur-api-rs-e2e -n centaur-sandbox-e2e run api-check --rm -i --restart=Never --image=curlimages/curl -- \
  curl -sS "$SANDBOX_HOST_API_URL/healthz"

If the pod check fails, switch SANDBOX_HOST_API_URL between host.docker.internal and host.orb.internal, restart api-rs, and retry.

4. Run Slackbot V2 Locally

In a separate shell:

cd services/slackbotv2
PORT=3002 \
CENTAUR_API_URL=http://127.0.0.1:8080 \
SLACK_BOT_TOKEN="$SLACK_BOT_TOKEN" \
SLACK_SIGNING_SECRET="$SLACK_SIGNING_SECRET" \
SLACKBOT_API_KEY="$SLACKBOT_API_KEY" \
SLACKBOTV2_DATABASE_URL="$DATABASE_URL" \
bun run dev

Check:

curl -sS http://127.0.0.1:3002/health

5. Expose Slackbot With Tailscale Funnel

tailscale funnel --bg --yes 3002
tailscale funnel status

Use the reported HTTPS URL plus /api/webhooks/slack as the Slack Request URL:

https://<machine>.<tailnet>.ts.net/api/webhooks/slack

Stop/reset when done:

tailscale funnel reset

6. Slack App Manifest

Use the Slack app UI manifest editor or Slack CLI. Set the Request URL to the Funnel URL from the previous step, reinstall the app after manifest changes, then refresh SLACK_BOT_TOKEN and SLACK_SIGNING_SECRET if Slack rotated them.

Minimal manifest shape:

display_information:
  name: Centaur Dev
features:
  bot_user:
    display_name: centaur-dev
    always_online: true
oauth_config:
  scopes:
    bot:
      - app_mentions:read
      - assistant:write
      - channels:history
      - channels:read
      - chat:write
      - groups:history
      - groups:read
      - im:history
      - im:read
      - mpim:history
      - mpim:read
      - users:read
settings:
  event_subscriptions:
    request_url: https://<machine>.<tailnet>.ts.net/api/webhooks/slack
    bot_events:
      - app_mention
      - message.channels
      - message.groups
      - message.im
      - message.mpim
  interactivity:
    is_enabled: true
    request_url: https://<machine>.<tailnet>.ts.net/api/webhooks/slack
  org_deploy_enabled: false
  socket_mode_enabled: false
  token_rotation_enabled: false

Do not put API-key auth in front of /api/webhooks/slack; Slackbot validates Slack signatures and then calls api-rs.

7. Use centaur-session-cli

Build/run from services/api-rs.

Create a new thread in the TUI:

CENTAUR_API_URL=http://127.0.0.1:8080 \
cargo run -p centaur-session-cli -- --tui --harness-type codex

The CLI prints thread_key=cli:<uuid> for new threads. In the TUI, type a message and submit it.

Create a new non-TUI smoke turn:

CENTAUR_API_URL=http://127.0.0.1:8080 \
cargo run -p centaur-session-cli -- \
  --harness-type codex \
  --message "Reply with exactly PONG and nothing else." \
  --exit-on-terminal \
  --max-duration-ms 120000

Follow a Slack thread by durable thread key:

CENTAUR_API_URL=http://127.0.0.1:8080 \
cargo run -p centaur-session-cli -- \
  --attach \
  --thread-key 'slack:<CHANNEL_ID>:<THREAD_TS>' \
  --all-events

Attach with TUI:

CENTAUR_API_URL=http://127.0.0.1:8080 \
cargo run -p centaur-session-cli -- \
  --attach \
  --thread-key 'slack:<CHANNEL_ID>:<THREAD_TS>' \
  --tui

Resume from an event id:

cargo run -p centaur-session-cli -- \
  --thread-key 'slack:<CHANNEL_ID>:<THREAD_TS>' \
  --after-event-id <LAST_EVENT_ID> \
  --all-events

For non-TUI interactive input, add --stdin-events. Lines are messages by default; /message <text>, /input <raw-json-line>, /execute <json-array-or-line>, and /quit are supported.

8. Smoke The Full Path

  1. Mention the Slack app in the configured workspace/channel.
  2. Confirm Slackbot logs show slackbotv2_forward_started.
  3. Confirm api-rs logs show session creation/execution and no mock workload.
  4. Confirm Kind created an Agent Sandbox:
kubectl --context kind-centaur-api-rs-e2e -n centaur-sandbox-e2e get sandboxes,pods
  1. Attach to the Slack thread key with centaur-session-cli and verify events replay.

Troubleshooting

  • Mock output instead of Codex: restart api-rs with SESSION_SANDBOX_BACKEND=agent-k8s and SESSION_SANDBOX_WORKLOAD=codex-app-server.
  • Sandbox cannot call API/tools: verify SANDBOX_HOST_API_URL from inside a Kind pod and restart api-rs with the working value in SESSION_SANDBOX_CENTAUR_API_URL.
  • Agent or iron-proxy image pull failure after changing images: rebuild and run KIND_E2E_FORCE_IMAGE_LOAD=1 just kind-e2e-load-images; keep SESSION_SANDBOX_IMAGE_PULL_POLICY=IfNotPresent and KUBERNETES_IRON_PROXY_IMAGE_PULL_POLICY=IfNotPresent.
  • Iron-proxy missing CA: rerun CENTAUR_NAMESPACE=centaur-sandbox-e2e just bootstrap-secrets and verify centaur-firewall-ca plus centaur-firewall-ca-key exist.
  • Model auth failure: check api-rs sandbox env says CODEX_AUTH_MODE=api_key, iron-proxy is enabled, and FIREWALL_MANAGER_SECRET_SOURCE=onepassword has the expected OP_SERVICE_ACCOUNT_TOKEN/OP_VAULT in centaur-infra-env.
  • Slack does not reach the bot: tailscale funnel status, Slack Request URL must end in /api/webhooks/slack, and SLACK_SIGNING_SECRET must match the app.
  • Slackbot receives events but does not stream: check SLACKBOTV2_DATABASE_URL, Slack assistant:write scope, and chat.startStream/chat.appendStream errors in Slackbot logs.
  • Re-run sandbox invariant tests when changing sandbox/runtime behavior:
cd services/api-rs
just e2e-kind
