📝 Walkthrough

Walkthrough

This PR adds Context7 MCP server integration to the agent skills documentation and configuration, then refactors the chat API handler to access Cloudflare Worker bindings through the request context instead of direct imports, updates missing-binding error responses from 500 to 503, and refactors tests to use per-test environment injection.

Changes

Context7 MCP Server Integration

Layer / File(s)	Summary
Context7 skill documentation and agent listing .agents/skills/context7/SKILL.md, AGENTS.md	Introduces the Context7 skill with its purpose, usage workflow (library IDs, queries, ID resolution, and agent rules), and example prompts; adds context7 to the documented MCP server list and registers the skill in the agent skills section.
Context7 configuration and setup documentation mcp_config.json, docs/mcp.md	Registers context7 as a new MCP server with endpoint and API key header configuration; documents editor-specific setup for Cursor and Claude Desktop, and provides automated CLI setup workflow instructions.

Chat API Handler Binding Refactoring

Layer / File(s)	Summary
POST handler signature and binding access update src/pages/api/chat.ts	Changes the POST route handler signature to accept full context instead of destructured request, removes the direct cloudflare:workers import, updates AI and KV binding access to read from context.locals.runtime.env via type assertion, changes missing-AI error response from 500 to 503, and adds Cache-Control: no-store and X-Content-Type-Options: nosniff headers to the SSE stream response.
Test context and environment injection helpers src/__tests__/chat-api.test.ts (helpers section)	Refactors test setup to replace the shared mutable mockEnv with per-test environment injection; updates createContext to accept and store a runtimeEnv parameter under locals.runtime.env; updates postChat helper to inject { AI: ai, CHAT_STORE: undefined } directly into the context; adjusts the AI mock typing from vi.fn<() => Env>() to vi.fn<() => Promise<ReadableStream>>().
Error scenario and rate-limiting test updates src/__tests__/chat-api.test.ts (test cases)	Expands error handling coverage with three distinct 503 scenarios (missing AI binding, missing locals.runtime, missing locals.runtime.env), each asserting the exact JSON error message; updates the invalid JSON test to use the new env-injection path; updates all rate-limiting tests (exceeded, increment counter, counter initialization) to pass environment via createContext instead of global mutation; adjusts AI failure mock cases to use the new typed vi.fn with proper rejection shapes.
