The pattern is already reviewed and approved. It handles both cases: called from inside an existing Tokio runtime (e.g., future-proofing) and called from a plain sync thread (current CLI paths). + +### Decision: `update_check.rs` spawn strategy + +**Choice**: `spawn()` creates a new `tokio::runtime::Runtime` scoped to the task and runs the async check via `Runtime::block_on` on a detached `std::thread`.

(b) Move update check into an async main — rejected; out of scope per proposal. (c) Bridge pattern in `spawn()` — rejected; adds complexity with no benefit since there's no pre-existing runtime to reuse. + +**Rationale**: `main.rs:188` calls `spawn()` once at startup on a detached `std::thread`. Creating a dedicated `Runtime` for this one-shot task is the simplest correct approach. `std::thread` is retained for the OS thread wrapper (naming, background behavior) but the actual HTTP work runs on the Tokio runtime. + +### Decision: Error context on HTTP failures + +**Choice**: Add a new `UpdateCheckError` enum with variants `Timeout`, `Connection`, `HttpStatus`, `ParseError` — replacing the silent `.ok()?` fallthrough in `fetch_latest_version`. Each network variant carries `url` plus a contextual field so diagnostics identify the failing request. + +```rust +#[derive(Debug, thiserror::Error)] +pub enum UpdateCheckError { + #[error("update check timed out after {duration_secs}s for url {url}")] + Timeout { url: String, duration_secs: u64 }, + #[error("connection failed for {url}: {reason}")] + Connection { url: String, reason: String }, + #[error("unexpected HTTP status {status} for {url}")] + HttpStatus { url: String, status: u16 }, + #[error("failed to parse version: {0}")] + ParseError(String), +} +``` + +**Alternatives considered**: Using `anyhow` for all errors — rejected; the success criteria requires categorizing errors (timeout vs. connection vs. status). `thiserror` gives structured variants for QA and logging. + +**Rationale**: Aligns with `SkillInstallError` in `install.rs` which already uses `thiserror` with `Network` variants. Structured errors make the acceptance criteria verifiable.

Keeping the OS thread wrapper and creating a dedicated Tokio runtime for this one-shot task is the cleanest path — `main.rs` has no Tokio runtime at all, so `tokio::spawn` is not an option there. + +Implementation: keep `std::thread::Builder::new().name("agentsync-update-check")` and inside the thread create `tokio::runtime::Runtime::new()` and run `rt.block_on(check_and_notify_async())`. The `fetch_latest_version` function becomes `async fn fetch_latest_version_async()` using `reqwest::Client` (not blocking). + +#### 2. `src/skills/provider.rs` — `resolve_via_search()` +**Current**: blocking reqwest called from synchronous CLI paths (suggest/install commands). +**Target**: async reqwest using the bridge pattern from `install.rs:244-253`. + +The bridge pattern checks for an existing Tokio runtime and either runs the async operation inline or spins up a temporary runtime: + +```rust +let result = match tokio::runtime::Handle::try_current() { + Ok(handle) => handle.block_on(async_http_call()), + Err(_) => { + let rt = tokio::runtime::Runtime::new().map_err(MyError::AsyncSetup)?; + rt.block_on(async_http_call()) + } +}; +``` + +This mirrors exactly what `install.rs:244-253` does with `fetch_and_unpack_to_tempdir`. The async HTTP call helper is extracted as `async fn resolve_via_search_http(source: &str) -> Result<...>`. + +#### 3. `tests/test_catalog_integrity.rs` — E2E test +**Current**: synchronous test using `reqwest::blocking::Client`. +**Target**: `#[tokio::test]` using `reqwest::Client`. + +The test function becomes `async fn` with `#[tokio::test]`. The blocking client builder is replaced with `reqwest::Client::builder()`. Retry logic stays the same.
