1. Unsafe double-cast chatpostcontext 📜 Skill insight ✧ Quality
The new test code uses as unknown as ... double-casts to force types for process.env.AI and context, bypassing TypeScript's type safety and potentially masking real type/interface mismatches. This violates the rule disallowing non-standard/unsafe as casts.
Agent Prompt
## Issue description
`src/__tests__/chat-api.test.ts` introduces `as unknown as ...` double-casts to coerce values into types (`(typeof process.env)['AI']` and `ChatPostContext`). This bypasses type checking and is explicitly disallowed.
## Issue Context
The test sets `process.env.AI` and builds a `ChatPostContext`-like object, but instead of constructing a correctly typed object (or updating helper typings), it forces the types via double-casting.
## Fix Focus Areas
- src/__tests__/chat-api.test.ts[494-502]
## Suggested approach
- Avoid `as unknown as ...`.
- Make `createAi()` return the correct type expected by `process.env.AI` (or define a typed test helper for the AI binding) so you can write `const ai: (typeof process.env)['AI'] = createAi();` without casting.
- Construct a fully valid `ChatPostContext` object and use `satisfies ChatPostContext` to type-check it, adding any required missing fields rather than force-casting.

2. Leaky global stubs 🐞 Bug ☼ Reliability
The new github-releases caching tests stub global window/sessionStorage but never restore them, so subsequent tests can observe mocked globals rather than jsdom’s originals. This creates order-dependent failures (especially since the last added test stubs sessionStorage without setItem).
Agent Prompt
### Issue description
`src/__tests__/github-releases.test.ts` uses `vi.stubGlobal` in multiple tests (including the newly-added cache JSON edge cases) but does not consistently call `vi.unstubAllGlobals()` afterward. In a `jsdom` test environment, this can leak mocked `window`/`sessionStorage` into later tests and make the suite order-dependent.
### Issue Context
Vitest is configured to run in `jsdom`, so other tests expect real jsdom globals by default.
### Fix Focus Areas
- src/__tests__/github-releases.test.ts[11-16]
- src/__tests__/github-releases.test.ts[242-363]
- vitest.config.ts[3-16]
### Suggested fix
Add an `afterEach(() => vi.unstubAllGlobals())` (and if needed `vi.unstubAllEnvs()`) near the top-level `describe`, and remove ad-hoc un-stubs that become redundant, or ensure each test that stubs globals uses `try/finally` to restore them.

3. Env restore not in finally 🐞 Bug ☼ Reliability
The new chat-api test replaces process.env and restores it only at the end of the test; if POST() throws or an assertion fails before cleanup, later tests will see a modified process.env. This can cause hard-to-debug, order-dependent test failures.
Agent Prompt
### Issue description
`src/__tests__/chat-api.test.ts` mutates the global `process.env` in the new test and restores it only at the bottom of the test body. Any thrown error before the restore line will leak the modified environment into subsequent tests.
### Issue Context
This file already contains a similar pattern in the prior test; the new test repeats it, increasing the risk of cross-test contamination.
### Fix Focus Areas
- src/__tests__/chat-api.test.ts[475-509]
### Suggested fix
Wrap the `process.env` mutation in `try/finally`:
```ts
const originalEnv = process.env;
try {
process.env = { ...originalEnv, AI: ... };
...
} finally {
process.env = originalEnv;
}
```
Alternatively, centralize cleanup with an `afterEach` that restores `process.env`.
