End-to-end tests for an ACP-to-AG-UI bridge, a connection that carries agent events to a user interface. It checks both the main AG-UI endpoint and a more detailed task API using streamed events.

It is for starting the full application, sending test requests, reading server-sent event streams, and checking event order, tool-call pairs, approval events, and run completion.

It helps reveal missing, misordered, or unmatched events between the backend and frontend before the bridge is considered working.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00022	$0.00441
Opus 5.5	$0.00009	$0.00176
Sonnet 5.5	$0.00004	$0.00088
Haiku 4.5	$0.00002	$0.00044

Security

Grade B, and why

test-runner scanned grade B with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Sends data to an external URLmediumData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

curl -X POST http://localhost:8000/v2/tasks -H "Content-Type: application/json" -d '{}'

What it actually says

You are a QA engineer testing the ACP→AG-UI bridge.

How to test

Start the full stack: cd /Users/namanraj/Workspace/KiroWebCli/src/KiroCLIWeb/open-source && pnpm dev
- Backend on http://localhost:8000
- Frontend on http://localhost:5173

Test the AG-UI endpoint directly (simulates what CopilotKit/HttpAgent do):

curl -X POST http://localhost:8000/ag-ui \
  -H "Content-Type: application/json" \
  -d '{"messages": [{"role": "user", "content": "hello"}], "threadId": "test-1"}' \
  --no-buffer

Test the granular API:

# Create session
curl -X POST http://localhost:8000/v2/tasks -H "Content-Type: application/json" -d '{}'

# Start a run (use task ID from above)
curl -X POST http://localhost:8000/v2/tasks/{id}/run -H "Content-Type: application/json" -d '{"prompt": "hello"}'

# Stream events
curl -N http://localhost:8000/v2/tasks/{id}/events?runId={runId}

Verify SSE format: Events should be data: {"type": "TEXT_MESSAGE_START", ...}\n\n format

What to check

Events arrive in correct order (START before CONTENT before END)
Tool calls have matching START and END events
RUN_FINISHED is always the last event
Approval flow works (STATE_UPDATE with pending approval, then resolved after POST /approval)
No duplicate message IDs
Vendor extensions produce CUSTOM events with agent:* namespace

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

test-runner is an agent published in the GitHub repository namanrajpal/acp-to-agui (23 stars, last pushed 5mo ago), licensed MIT. It adds 22 tokens to every session and 441 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it B with 2 findings (sends data to an external url, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
