Endpoint Probe

Endpoint Probe

Smoke-test the dashboard's main API surface by hitting each major route once and reporting whether it responds and what shape it returns.

Input

The user provides: $ARGUMENTS

Options: empty (default: probe all routes below), or a substring to filter which routes are probed (e.g. pricing probes only matching routes).

Data Sources

| Endpoint | Returns | |----------|---------| | GET /api/stats | { total_sessions, active_sessions, active_agents, total_agents, total_events, events_today, ws_connections, agents_by_status, sessions_by_status } | | GET /api/analytics | { overview, tokens, tool_usage, daily_events, daily_sessions, agent_types, event_types, avg_events_per_session, total_subagents, sessions_by_status, agents_by_status } | | GET /api/sessions | Session list; each: id, status, model, cwd, started_at, ended_at, cost, metadata | | GET /api/pricing/cost | { total_cost, breakdown:[{ model, input_tokens, output_tokens, cache_read_tokens, cache_write_tokens, cost, matched_rule }] } | | GET /api/workflows/runs | Workflow-tool run journals (fleets) | | GET /api/cc-config/overview | Claude Code config explorer overview (skills, agents, commands, plugins, mcp, hooks, etc.) |

Method

For each route, issue a single GET against http://localhost:4820 with a short timeout, capturing the HTTP status code, round-trip latency, and the top-level shape of the JSON body (object keys, or array length). A route counts as reachable when it returns a 2xx with parseable JSON.

If /api/stats itself fails to connect, the dashboard is not running — stop and tell the user to start it with npm start (or npm run dev) from the repo root.

Report Sections

1. Probe Matrix

A Markdown table — one row per route — with columns: endpoint, status (HTTP code), latency, reachable (✅/❌), shape (e.g. object: {total_cost, breakdown[…]} or array[N]).

2. Reachability Summary

Count of reachable vs total. Name any unreachable or non-2xx routes explicitly.

3. Verdict

One line: install looks healthy (all reachable) or partially wired (list the gaps and the most likely cause — server not running, route disabled, or empty data).

Output

• Compact Markdown; the probe matrix is the centerpiece.
• Cite the real status code, latency, and observed shape per route — never assume.
• Report shape from what actually came back; if a route returns an empty array or

object, say so rather than inferring fields.

• Keep currency, where shown, to 4 decimals (e.g. total_cost: $0.0000).
