Add Tavily provider

Port from upstream CodexBar v0.74.1. Upstream plugin, descriptor, and plugin tests are the spec.

Behavior

  • Bars "Plan credits" and "API key"; sections "Account plan", "API key", and "Pay as you go" when present, each with Used / Limit / Remaining in credits.
  • Unlimited API-key limit: no API-key bar, Limit "Unlimited", no Remaining row.
  • Errors: "Tavily returned HTTP .".

Matches the Mac v0.74.1 captures for success, 401, and unlimited-key states.

Checks (local full-checks.sh on the tree pushed as d9a3e393a)

  • cargo fmt --all -- --check: clean
  • cargo test --manifest-path rust/Cargo.toml: 4148 passed, 1 ignored
  • cargo clippy on both manifests with -D warnings: clean
  • cargo test --manifest-path apps/desktop-tauri/src-tauri/Cargo.toml: 707 passed
  • pnpm test, tsc, pnpm run build (apps/desktop-tauri): pass
    Log: W:/mac-parity/report/provider-tavily/checks-470dffc3c/SUMMARY.txt

Review follow-up (d9a3e393a)

  • The HTTP client fails closed instead of falling back to Client::new().
  • Local HTTP fixtures cover 200 with bearer auth, and 429 and 302 each sending exactly one request.
  • Added samples for a wrong-typed and a null PAYG field; both are rejected.
  • Frontend: 1106 Vitest tests passed; tsc and pnpm run build pass.

Windows proof

Captured before the review follow-up, which changes error mapping and tests only, so the captured screens are unchanged.
Fresh proof build from the pre-review head, captured against mock routes:
W:/mac-parity/report/provider-tavily/proof-470dffc3c/COMPARISON.md.

Summary by CodeRabbit

  • New Features
    • Added Tavily as a supported provider, with API-key setup and account-plan, API-key, and pay-as-you-go usage details.
  • Bug Fixes
    • Usage sections and provider cards now omit metrics marked as hidden while retaining other visible usage details.
  • Documentation
    • Added Tavily setup and usage information to the provider documentation.

- Implement Tavily API usage fetcher for account plan, API key, and pay-as-you-go credits
- Bearer-authenticated GET /usage endpoint with account and key-level meters
- Ported from upstream CodexBar v0.74.1 (Resources/Plugins/tavily.js)
- Add Tavily variant to ProviderId enum and wire into factory (count: 96 -> 97)
- Add Tavily to providers/mod.rs module exports and provider_factory instantiate/pace_capability
- Add Tavily to token_accounts exhaustive match (returns None; API-key provider)

📝 Walkthrough

This change adds Tavily as a provider and retrieves usage data from its /usage endpoint. It also excludes usage windows marked hiddenOnCard from desktop usage descriptors and settings rows.

Changes: Tavily usage provider

Layer / File(s) Summary
Register and route Tavily
rust/src/core/provider.rs, rust/src/core/provider_factory.rs, rust/src/core/token_accounts.rs, rust/src/providers/mod.rs, rust/src/settings/api_keys.rs
Adds Tavily to provider identifiers, names, CLI parsing, metadata, API-key configuration, factory construction, and capability mappings.
Fetch and parse Tavily usage
rust/src/providers/tavily/mod.rs, apps/desktop-tauri/src/components/providers/providerIcons.ts, apps/desktop-tauri/src/test/providerCatalog.ts, README.md, docs/PROVIDERS.md
Adds the /usage request flow, source handling, response validation, and usage conversion. Adds Tavily to the desktop catalog and icon registry, and documents API-key setup and usage data. Tests cover parsing, request behavior, and error mapping.

Hidden usage windows

Layer / File(s) Summary
Filter card-hidden usage windows
apps/desktop-tauri/src-tauri/src/commands/usage_items.rs, apps/desktop-tauri/src-tauri/src/commands/tests.rs, apps/desktop-tauri/src/surfaces/settings/providers/sections/UsageSection.tsx, apps/desktop-tauri/src/surfaces/settings/providers/sections/UsageSection.test.tsx
Usage descriptors and settings rows now omit windows marked hidden on the card. Tests verify that hidden windows are omitted while visible usage windows and details remain.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: ⚪ Minimal · up to fa6e2

The Tavily provider now rejects negative and malformed usage values instead of showing them as valid usage. The only remaining item is a small test-coverage suggestion, so there is no actionable merge-blocking risk.

Full details: Provider Data Stays Siloed

Explanation

The standing failure remains. The pull request adds ProviderId::Tavily branches in shared rust/src/core/provider.rs for the provider list, CLI name, display name, cookie domain, CLI parsing, and brand color. It also adds ProviderId::Tavily to the shared capability match in rust/src/core/token_accounts.rs. These files are outside rust/src/providers/tavily/ and rust/src/core/provider_factory.rs, so they violate the explicit cross-provider branching condition.

Resolution

Remove the Tavily-specific branches from shared files outside the allowed paths. Move provider metadata and capability behavior to provider-owned metadata or neutral generic mechanisms, so Tavily registration does not require ProviderId::Tavily matches in rust/src/core/provider.rs or rust/src/core/token_accounts.rs.

Review comments at @rust/src/providers/tavily/mod.rs:
- Line 71: Update the HTTP client builder fallback in the Tavily provider to
return or propagate the build error instead of substituting Client::new,
preserving the configured 15-second timeout and no-redirect policy for
credentialed requests.
- Around line 90-113: Add deterministic HTTP-response tests for the fetch path
that cover a successful 200 response, a 429 response, and a 3xx response. Assert
that 429 is not retried and redirects are not followed; use the existing
fetch-path test helpers and keep the status-handling behavior in the response
match unchanged.
- Around line 194-197: Validate plan_usage, plan_limit, and key.usage as
nonnegative before building a usage window; reject negative values with the
existing parse-error path so they cannot be treated as unused credit. Update the
parsing flow around plan_usage and apply the same validation to the other
reported counts.
- Line 210: Update the `key_limit` parsing to accept an explicit JSON null as
unlimited, while returning a parse error when `limit` is missing or has a
non-integer type; do not treat `as_i64()` returning `None` as unlimited for all
cases.
- Around line 169-175: Update Tavily’s `into_result` flow to carry reported
pay-as-you-go and account-plan used/limit counts into usage details, including
zero-limit plans and keys with null limits. Preserve missing percentages as
absent rather than converting them to a 0% `RateWindow`, while retaining the
existing plan and secondary-window data.

🟡 Minor · Reject malformed key.limit and PAYG fields. · mod.rs:189-193

rust/src/providers/tavily/mod.rs:189-193
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Reject malformed key.limit and PAYG fields.

Line 189 turns a present but wrongly typed limit into None. For example, "limit": "200" becomes an unlimited key. Lines 192-193 do the same for paygo_usage and paygo_limit. The PAYG pairing check then accepts the response and drops the PAYG details. Accept absent or JSON null as "not set". Return ProviderError::Parse for any other non-integer value. Add test samples for both cases.

As per path instructions: "Flag fetch or parse changes that come without deterministic samples or fixtures."

Proposed fix
-    let key_limit = key.get("limit").and_then(|v| v.as_i64());
+    let opt_int = |obj: &serde_json::Map<String, Value>, name: &str| -> Result<Option<i64>, ProviderError> {

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Reject negative usage counts.

plan_usage and key.usage accept negative integers. With a positive limit, each produces a 0% window while the details display a negative Used value. plan_limit is already rejected unless it is positive, so validate only the two usage fields here.
