Splits part of #1084 into a focused PR, as requested there.

Depends on #1100 (custom API request body). The branch is based on that branch, so this diff currently includes its commit as well; it shrinks to just the connection test once #1100 merges. The probe deliberately merges the configured extra request body, so it needs that setting to exist.

What this does

The API Modes settings can now probe a configured provider with the smallest request that still proves the endpoint, key and model work together: one token, one "ping" message, no streaming. Test runs from each OpenAI-compatible / Azure / Anthropic row, and from the custom model field on the General tab.

Each provider family is probed through the same request shape its live path uses, so a mode that passes here is one that can be talked to:

  • OpenAI-compatible: same resolved URL, token parameter resolved from the provider rather than the raw id (max_completion_tokens for OpenAI-lineage GPT-5 models), completion modes send prompt + max_tokens instead of messages, and the extra request body is merged in.
  • Azure: deployment URL + api-key header.
  • Anthropic: /v1/messages with x-api-key / anthropic-version and the same thinking configuration as the live path.

Safety and correctness details:

  • Modes with no request shape (browser/cookie modes, the third-party relay, Ollama's native /api/chat endpoint) report unsupported-provider instead of a misleading red failure, and the Test action is not rendered for them.
  • Probes use redirect: 'manual', so credentials cannot be sent to whatever host a redirect points at; a redirect is reported as a failure.
  • Timeouts (20 s) and transport failures are reported as data, never thrown.
  • Results are keyed by mode identity rather than row index, so reordering rows cannot move a result, and the outcome is shown on the button itself (label, colour, tooltip) so the row layout stays stable.
  • The button is disabled while a probe is pending, so an older response cannot overwrite a newer one.

Requested in #916.

Tests

  • tests/unit/services/apis/test-connection.test.mjs — request shaping per provider family, the extra-body merge, unsupported modes, the Ollama guard, redirects and transport failures.
  • tests/unit/services/apis/connection-test-groups.test.mjs — which groups are testable.
  • tests/unit/popup/connection-test-status.test.mjs — button label/colour/tooltip mapping.

Validation

  • npm test — 1119 passing.
  • npm run lint — clean.
  • npm run build — all four variants build; expected artifacts present in build/chromium/.

Validation skipped: manual browser testing — no browser automation is available here. A smoke test would run Test against a working and a broken endpoint and check the button state.

Review in cubic

Summary by CodeRabbit

  • New Features
    • Added an optional JSON field for extra API request parameters. Valid object values are merged into supported provider requests; invalid or non-object JSON is flagged.
    • Added connection testing for supported API modes, including custom model endpoints, with pending, reachable, and unreachable status and elapsed-time feedback. Unsupported endpoints are identified as not testable.

ecokayiza and others added 2 commits October 3, 2026 17:39
Expose a JSON textarea under Advanced > API Params that merges user-provided fields into the OpenAI-compatible, Azure OpenAI and Anthropic request bodies, so parameters the extension does not surface (thinking, reasoning_effort) can be sent.

The stream key stays under extension control to keep SSE replies intact.

The API Modes settings can now probe a configured provider with the smallest
request that still proves the endpoint, key and model work together: one
token, one "ping" message, no streaming.

Each provider family is probed through the same request shape its live path
uses, so a mode that passes here is one that can be talked to:

- OpenAI-compatible modes resolve their URL, token parameter and extra request
  body exactly like a real request.
- Azure probes its deployment URL with the `api-key` header.
- Anthropic probes `/v1/messages` with `x-api-key` and the same thinking
  configuration as the live path.

Modes with no request shape (browser/cookie modes, the third-party relay,
Ollama's native chat endpoint) report "unsupported" instead of a misleading
failure. Probes use `redirect: 'manual'` so credentials cannot be sent to
whatever host a redirect points at, time out after 20 s, and report transport
failures and HTTP errors as data rather than throwing.

Results are keyed by mode identity rather than row index and are shown on the
Test button itself, so reordering rows cannot move a result and the row layout
stays stable. The Test button is disabled while a probe is pending, so an
older response cannot overwrite a newer one.

Merge Risk: 🟡 Moderate · up to 23231

Connection tests can expose a key over non-local HTTP or report a provider as reachable when its response is invalid. Resolve those issues and the Anthropic probe mismatch before merging; the custom-model button also needs a pending-state fix.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 23231

Connection tests reuse existing provider credentials and destination selection, and prevent redirect forwarding. Credentials can still be sent to user-configured non-local HTTP endpoints, but this exposure already exists in normal API calls. End-to-end sender enforcement and consistency between test and live transport policies remain incompletely verified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — For plaintext credential exposure, the independently affected scope is the credential selected for a provider request in an installation. A network observer on a configured non-local HTTP path could obtain that credential and inherit its provider-side permissions. Those permissions, account-wide access, and tenant reach are not established by the repository evidence; loopback defaults alone do not establish remote exposure.

Security Findings and Attack Paths

  • observed — The two retained sensitive-data findings concern credential-bearing initial requests without an HTTPS-only destination requirement. Comparison with the available base shows the same credential and HTTP destination exposure in live provider calls before this PR. The probe reproduces that condition; no greater effective credential scope is established. Manual redirects do not protect the first HTTP transmission.

Trust Boundaries and Controls

  • observed — The sender policy trusts same-extension IDs, including content scripts on ordinary web pages; it is not a popup-only boundary. Without an ID, it requires an extension URL. Predicate tests explicitly accept content-script-shaped metadata and reject ordinary web-page, other-extension, and empty senders. The listener invokes this gate before credential access, but browser metadata provenance and end-to-end handler behavior remain coverage gaps.

Resilience and Maintainability Implications

  • observed — Probe execution uses direct fetch instead of the live shared transport. Consequently, it does not explicitly apply the live HTTP(S)-only and no-URL-userinfo validator. This is a policy-enforcement divergence, not proof of broader exploitable authority: browser fetch may reject unsafe URL forms, and complete effective parity has not been demonstrated.

Hardening Proposals

  • proposed — Define a shared credentialed-destination policy for live and probe requests, explicitly distinguishing encrypted remote endpoints from intentional local HTTP use. Applying the same URL validation policy to both transports would reduce reliance on platform-specific behavior and future control drift.

High-Level Assessment

The following are alternative approaches to this PR:

1. Extract shared provider request builders
  • ➕ Keeps probe and live request shaping aligned as provider behavior changes.
  • ➖ Requires a broader refactor of three live request paths for this focused feature.

Recommendation: The focused probe is a reasonable choice for this PR and reuses existing provider resolution and token-shaping helpers. Shared request builders would be preferable if probe/live-path drift emerges, but add substantially more scope now.

Grey Divider


Action required

1. Endpoints that stall can look reachable 🐞 Bug ≡ Correctness
Description
sendTestRequest returns success as soon as it receives successful HTTP headers, without reading
the body, and clears its timeout at that point. An endpoint that sends 200 but stalls or emits an
Anthropic stream error is marked reachable even though the live request must consume that stream and
can fail.
Code

src/services/apis/test-connection.mjs[146]

+    return { ok: true, status: response.status, elapsedMs }
Evidence
The probe never reads a successful response and clears its abort timer on return. The live Claude
handler rejects error events and requires a completed stream.

Remediation recommended

2. Test result stays after the URL or key is edited 🐞 Bug ≡ Correctness
Description
In GeneralPart, connectionTest is stored without the custom-model URL, name, or credential it
tested, and ApiModes.getConnectionTestKey omits the resolved provider URL and secret from its
result identity. Editing those settings can leave an old result displayed for the new configuration,
including when a probe started before the edit finishes afterward.
Code

src/popup/sections/GeneralPart.jsx[R108-113]

+  const [connectionTest, setConnectionTest] = useState(null)
+
+  const runCustomModelConnectionTest = async () => {
+    // Ignore repeat clicks while a probe is running, so a stale result cannot win.
+    if (connectionTest?.pending) return
+    setConnectionTest({ pending: true })
Evidence
GeneralPart writes connectionTest in runCustomModelConnectionTest, but its settings handlers
do not clear the result, and the button derives its label and style directly from that shared value;
probe completion can also replace it after an edit. In ApiModes, the result key excludes
credentials and the resolved provider URL, while provider resolution can use a mode-specific API key
or a configured provider secret, so retrieving a result by the unchanged key can show an outcome
from the previous settings.

Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
Connection-test results can remain visible after the URL, model name, API key, or resolved provider settings used by the test change. A probe already in flight can also publish an outcome for settings that are no longer displayed.

- src/popup/sections/ApiModes.jsx[81-93]
- src/popup/sections/ApiModes.jsx[293-310]

## Recommended Fix
In `GeneralPart`, associate results with the tested configuration or clear `connectionTest` when the custom-model URL, name, or relevant API key/provider changes. Track in-flight probes so results started for earlier settings are discarded rather than displayed after an edit. In `ApiModes`, invalidate cached and in-flight results when a mode key or resolved provider URL or secret changes, either by including the resolved settings in the result identity or by clearing `connectionTests` when `customOpenAIProviders` or `providerSecrets` change. Do not expose credential values in rendered labels or tooltips.

3. Immediate tests can probe the old URL 🐞 Bug ≡ Correctness
Description
runCustomModelConnectionTest sends only a model selector, while the background test independently
reads persisted configuration. If a user edits the custom-model URL and immediately clicks Test, the
popup's queued storage write can still be pending, so the request uses the previously saved URL
rather than the one in the input.
Code

src/popup/sections/GeneralPart.jsx[R116-119]

+      result = await Browser.runtime.sendMessage({
+        type: 'TEST_API_CONNECTION',
+        data: { session: { modelName: 'customModel' } },
+      })
Evidence
The URL change starts an unawaited queued write, whereas the test message supplies no URL and the
background loads storage.

4. Probe failures show English-only details 📘 Rule violation ⚙ Maintainability
Description
sendTestRequest returns a hardcoded English redirect explanation, and the new probe also returns
fixed timeout and provider-resolution error strings without localization keys. The button tooltip
displays test.error directly, so these details bypass translation when a probe fails.
Code

src/services/apis/test-connection.mjs[139]

+        error: 'The endpoint redirected the request instead of answering it.',
Evidence
The probe returns a fixed English message on redirects, and the status helper interpolates returned
errors directly into a user-facing tooltip.

5. Most locales omit new settings text 📘 Rule violation ⚙ Maintainability
Description
The new request-body guidance and connection-test labels have keys in English and the two Chinese
locale files, but not in the other supported locale files. When those users open the settings, the
configured English fallback supplies the new text instead of a locale entry or marked placeholder.
Code

src/_locales/en/main.json[R134-137]

+  "Test": "Test",
+  "Testing...": "Testing...",
+  "Reachable": "Reachable",
+  "Unreachable": "Unreachable",
Evidence
English introduces the keys, but the resource registry includes ten other supported locales beyond
the two Chinese locales, and the cited French locale region has no corresponding entries.

7. A failing Claude token limit can pass 🐞 Bug ≡ Correctness
Description
resolveAnthropicTestMaxTokens raises the probe limit above an enabled thinking budget, while the
live Claude request uses config.maxResponseTokenLength without that adjustment. If the configured
response limit does not exceed the thinking budget, the probe tests a valid limit that the ensuing
conversation does not use.
Code

src/services/apis/test-connection.mjs[R87-89]

+  if (thinking?.type === 'enabled' && Number.isFinite(thinking.budget_tokens)) {
+    return Math.max(TEST_MAX_TOKENS, thinking.budget_tokens + 1)
+  }
Evidence
The probe deliberately chooses at least budget plus one, but the live body sends the configured
maximum and then applies the same extra thinking fields.

8. Completion tests omit a live parameter 🐞 Bug ≡ Correctness
Description
buildOpenAICompatibleTestRequest leaves the completion request's stop field out of its base

probe but rejects that parameter can show a successful test despite rejecting the subsequent
conversation request.

+      ? { model, prompt: TEST_PROMPT, ...tokenParams }

The probe constructs a completion body without stop; the live builder includes it before applying
user extra fields.

10. Tests can miss temperature failures ✓ Resolved
Description
The probe builders omit getTemperatureParams even though the live OpenAI-compatible, Azure, and
Anthropic builders include it. When a temperature override is enabled, the test sends a different
body, so acceptance of the probe does not establish that the configured conversation request will be
accepted.
Code

11. One global extra body breaks other providers 🐞 Bug ≡ Correctness
Description
getExtraBodyParams(config) reads a single global config.extraBody and merges it unchanged into
OpenAI-compatible, Azure and Anthropic request bodies, and into every probe. A field meant for one
provider, such as the placeholder's reasoning_effort for OpenAI, is also sent to Anthropic's
/v1/messages, which rejects unknown fields. Switching modes then fails both live chat and the new
connection test with a 400 error.
Code

src/services/apis/extra-body-params.mjs[R23-28]

+export function getExtraBodyParams(config) {
+  const extraBody = parseExtraBody(config?.extraBody)
+  if (!extraBody) return {}
+  // Every API request is read as an SSE stream, so this key stays under extension control.
+  delete extraBody.stream
+  return extraBody
Evidence
The extra body has one source, config.extraBody, with no per-provider or per-mode scoping. It is
spread into the Azure body, Object.assign-ed onto the Claude body, and spread into both
OpenAI-compatible bodies. test-connection.mjs merges it into every probe family, so a body written
for one provider shows other providers as Unreachable.

sendTestRequest returns success as soon as it receives successful HTTP headers, without reading
the body, and clears its timeout at that point. An endpoint that sends 200 but stalls or emits an
Anthropic stream error is marked reachable even though the live request must consume that stream and
can fail.

10. Test result stays after the url or key is edited 🐞 Bug ≡ Correctness

In GeneralPart, connectionTest is stored without the custom-model URL, name, or credential it
tested, and ApiModes.getConnectionTestKey omits the resolved provider URL and secret from its
result identity. Editing those settings can leave an old result displayed for the new configuration,
including when a probe started before the edit finishes afterward.
Agent Prompt
## Issue description
Connection-test results can remain visible after the URL, model name, API key, or resolved provider settings used by the test change. A probe already in flight can also publish an outcome for settings that are no longer displayed.

- src/popup/sections/ApiModes.jsx[293-310]

## Recommended Fix
In `GeneralPart`, associate results with the tested configuration or clear `connectionTest` when the custom-model URL, name, or relevant API key/provider changes. Track in-flight probes so results started for earlier settings are discarded rather than displayed after an edit. In `ApiModes`, invalidate cached and in-flight results when a mode key or resolved provider URL or secret changes, either by including the resolved settings in the result identity or by clearing `connectionTests` when `customOpenAIProviders` or `providerSecrets` change. Do not expose credential values in rendered labels or tooltips.

ℹ️ No critical issues — one probe-parity edge to look at.

Reviewed changes

  • Connection-test service — new src/services/apis/test-connection.mjs builds a minimal probe per provider family (OpenAI-compatible, Azure, Anthropic), mirrors the resolved URL/auth/token-param/extra-body, refuses browser/cookie/relay and native Ollama paths, and returns transport failures and redirects as data.
  • Test UI — Test buttons in src/popup/sections/ApiModes.jsx and src/popup/sections/GeneralPart.jsx, with result label/colour/tooltip in connection-test-status.mjs, keyed by mode identity and disabled while pending.
  • Testability gate & background plumbing — connection-test-groups.mjs plus the TEST_API_CONNECTION handler in src/background/index.mjs.
  • Extra request body (dependency commit from #1100) — extra-body-params.mjs, the Advanced-tab textarea, and the merge into the OpenAI-compatible / Azure / Anthropic live requests.
  • i18n & tests — en/zh-hans/zh-hant strings and the new unit suites (all passing).

The OpenAI-compatible and Azure probes faithfully mirror their live counterparts. One paraphrase to flag inline.

The probe raises max_tokens to budget_tokens + 1 when the configured extra body enables thinking, but the live path keeps max_tokens: config.maxResponseTokenLength and merges the thinking config on top unchanged. With the default maxResponseTokenLength of 2000 and the PR's own example {"thinking":{"type":"enabled","budget_tokens":2048}}, the probe gets a 200 while the live request is rejected with a 400 — so the button can show a green "Reachable" for a mode that cannot chat.

Technical details
# Anthropic probe compensates max_tokens, live path does not

## Affected sites
- `src/services/apis/test-connection.mjs:85-91` — `resolveAnthropicTestMaxTokens` raises the probe's limit to `budget_tokens + 1` whenever `extraBody.thinking` is enabled.
- `src/services/apis/test-connection.mjs:102` — the raised value is used as the probe's `max_tokens`.
- `src/services/apis/claude-api.mjs:36,42` — the live request keeps `max_tokens: config.maxResponseTokenLength` and then merges the user thinking config on top, with no compensation.

## Required outcome
`budget_tokens` must be less than `max_tokens` (except for interleaved thinking). The probe should fail in the same cases the live request fails, so a green "Reachable" implies chat will succeed.

## Suggested approach (optional)
When the extra body enables thinking, mirror the live value (`config.maxResponseTokenLength`) instead of `budget_tokens + 1`; otherwise keep the one-token probe. That restores parity and surfaces a too-small `Max Response Token Length` as `Unreachable` rather than masking it.

  • With extended thinking enabled, claude-api.mjs can send a max_tokens value below the thinking budget, making live Claude requests invalid. Raise it to at least budget_tokens + 1.
  • test-connection.mjs can report reachable for a request the live completion rejects: the probe changes max_tokens and omits the live stop field. Match the live payload so the probe reflects actual request validity.
  • extra-body-params.mjs applies provider-specific fields to every provider, which can break unrelated live requests and probes. Scope these fields to the relevant provider or API mode.
  • In GeneralPart.jsx, clicking Test immediately after editing a key can use the previous credential because persistence is asynchronous. Await the write or pass the current key to the probe.

Comment thread src/popup/sections/GeneralPart.jsx
The Advanced "Extra Request Body (JSON)" setting is merged after the
token parameters, so a user-provided max_tokens (or
max_completion_tokens) could ride along with the key the selected model
family actually uses, and OpenAI rejects a request that carries both.

Run the configured fields through the same conflict handling already
applied to provider-supplied bodies, keeping the user override of the
applicable key, and cover both token-key families plus the completion
endpoint in tests.
The probe could be reached with stored credentials for a caller-supplied
URL, and it diverged from the live request in ways that made broken modes
look healthy:

- TEST_API_CONNECTION accepted any sender, so the guard FETCH already had
  moves into a shared helper used by both, keyed off the runtime base URL
  so it matches in Firefox as well.
- A configured body could re-add the token key the model family does not
  use, which OpenAI rejects; the probe now drops it like the live path.
- The probe skipped the temperature override the live request sends, so
  an override the endpoint rejects could still report as reachable.
- A mode with no request shape to send now reports a neutral, translated
  state instead of a red Unreachable carrying a raw error code.
- A General tab result is retired when the URL, model or key it ran
  against changes, so it cannot linger as a stale colour.

Follow-up pushed in 232315f.

  • TEST_API_CONNECTION now goes through the same sender check FETCH already had; the guard moved to src/background/message-sender.mjs and keys off the runtime base URL, so it also matches id-less extension pages in Firefox.
  • The probe drops the token key the resolved model family does not use, the same way the live path does, so a configured max_tokens can no longer ride along with max_completion_tokens.
  • The probe sends the configured temperature override, which the live request sends too, so an override the endpoint rejects no longer reports as reachable.
  • A mode with no request shape to send (native Ollama chat URL) reports a neutral, translated "Not testable" instead of a red "Unreachable" carrying the raw unsupported-provider code.
  • A General tab result is retired once the custom model URL, name or key it was probed with changes, instead of lingering as a stale colour.

Validation on this branch: npm test 1127 passing, npm run lint clean, npm run build green with all four variants, and every changed file re-checked against the repo Prettier config. Manual browser smoke test still not run.

The branch also carries the #1100 token-key fix (6880978) so the probe and the live path stay in step before that PR lands; it will drop out on rebase.

Deliberately not changed here: the extra request body is still one global value merged into every provider family. Scoping it per provider, or at least saying so in the UI text, is a #1100 design decision and should be settled there.

ℹ️ No new issues in the incremental changes — the sender gate, token-limit filtering and temperature parity all check out. The prior open thread on Anthropic probe parity remains valid and is not addressed by the new commits, so I'm not approving yet.

Reviewed changes

  • Sender gating — extracted isTrustedExtensionSender into src/background/message-sender.mjs, applied it to TEST_API_CONNECTION, and replaced the inline FETCH check with it (equivalent to the previous origin-based logic).
  • Token-limit key filtering — the live OpenAI-compatible path and the probe now drop the token key the resolved model family does not use, so a configured extra body cannot send both max_tokens and max_completion_tokens.
  • Temperature parity — the probe and the live Azure/Claude/OpenAI-compatible paths now apply getTemperatureParams consistently.
  • Unsupported state — modes with no request shape return unsupported: true and render a neutral "Not testable" button (connection-test-status.mjs, new i18n key in en/zh-hans/zh-hant) instead of a red failure.
  • Custom-model result identity — the General-tab result is keyed by a URL + model + key signature, so editing any of them retires a stale result.
  • Tests — new sender-trust, token-key, temperature-override and unsupported-state assertions (28 targeted tests pass; lint/prettier clean).

Check the API response before reporting a successful connection.

A server can return 200 with an HTML login page or an API error payload. Line 160 reports that response as reachable without checking whether the provider answered the non-streaming ping. Read and validate a bounded response body before reporting success. Keep the timeout active during that read.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Allow a new test after the custom-model signature changes.

When the URL or model changes during a probe, customModelTest becomes null, so the Test button becomes enabled. The click guard still checks connectionTest?.pending and silently ignores that click for up to the old probe’s timeout. Check pending state for the current signature, and prevent an older completion from replacing the newer result.

Review comment at @src/popup/sections/GeneralPart.jsx at line 119:
Update the connection-test state and click guard in the GeneralPart flow to
consider a probe pending only when its signature matches the current
custom-model signature, so a changed URL or model can be tested immediately.
Ensure completion of an older probe cannot replace the result for the newer
signature.

  • tests/unit/background/message-sender.test.mjs doesn't cover the origin fallback in isTrustedExtensionSender, so a regression in that trust path could go unnoticed. Add a test that exercises a sender trusted through origin.

P3: The tests never exercise the `sender.origin` trust path even though `isTrustedExtensionSender` accepts `origin` as a fallback signal (src/background/message-sender.mjs line 13 and its JSDoc). Only `url` and `documentUrl` acceptance is asserted, so a regression that breaks or loosens the origin check would go unnoticed. Add a positive case (`{ origin: EXTENSION_PAGE_URL }`) and a negative case (`{ origin: 'https://example.com' }`) to the second and third tests.</violation>
