Rails Agent Gateway

This skill works in tandem with the agent_gateway Ruby gem, a mountable Rails engine that must be installed and configured on the Rails side (gem "agent_gateway" + initializer). This skill handles the OpenClaw-side setup and usage for pulling data from that endpoint.

Quick Workflow

1. Confirm required env vars are available.
2. Validate endpoint connectivity with a non-destructive briefing fetch.
3. Pull briefing data for a selected period/resources.
4. Summarize result counts, aggregations, and latest records.
5. If requested, prepare commands suitable for cron/automation.

Required Environment

Require these variables before any live fetch:

• AGENT_GATEWAY_TOKEN (bearer token — set in the Rails app initializer as c.auth_token)
• AGENT_GATEWAY_SECRET (path secret — set as c.path_secret)

The OpenClaw helper script may also read:

• RAILS_GATEWAY_URL (full /briefing URL, e.g. https://myapp.com/agent-gateway/<secret>/briefing)
• RAILS_GATEWAY_TOKEN (maps to bearer token)

If env vars are missing, stop and show the exact export commands needed.

Authentication

The gem uses two-layer auth:

1. Path secret — embedded in the URL (/agent-gateway/<secret>/briefing). Wrong value returns 404 (endpoint appears nonexistent).
2. Bearer token — sent via Authorization header. Wrong/missing value returns 401.

Both are compared using timing-safe secure_compare.

Command Patterns

Direct curl

curl -H "Authorization: Bearer $AGENT_GATEWAY_TOKEN" 
  "https://myapp.com/agent-gateway/$AGENT_GATEWAY_SECRET/briefing?period=7d&resources=users,orders"

Helper script

Prefer the local helper script when present:

/home/node/.openclaw/workspace/scripts/rails-gateway-briefing --period 7d

With explicit env vars:

RAILS_GATEWAY_URL='https://myapp.com/agent-gateway/<secret>/briefing' 
RAILS_GATEWAY_TOKEN='***' 
/home/node/.openclaw/workspace/scripts/rails-gateway-briefing --period 7d --resources users,orders

Query Parameters

Resource-Scoped Pulls

Resources are configured per-app via the gem's DSL. Common examples:

• --resources users
• --resources orders

Use --latest N to cap detailed rows while keeping counts.

The gem DSL also supports aggregations (count, sum, avg) on numeric columns — these appear in the response alongside count and latest.

Safety Rules

• Never print or echo live tokens in user-visible output.
• Redact secrets in pasted commands.
• Do not perform external write actions unless explicitly asked.
• Keep pulls read-only (briefing endpoint usage only).

Troubleshooting

If calls fail:

1. Confirm helper script exists and is executable.
2. Confirm endpoint URL includes /agent-gateway/<secret>/briefing.
3. Confirm bearer token is current (AGENT_GATEWAY_TOKEN).
4. Check two-layer auth: 404 = bad path secret, 401 = bad bearer token.
5. Retry with minimal scope (--resources users --period 7d --latest 1).
6. Report exact error class (auth/network/format), then propose a fix.
