Subject: [PATCH 2/8] Update Claude Code GitHub Action from beta to v1 (#3018)

Updates the Claude Code GitHub Action to use the stable v1 GA release instead of the beta version.

## Changes
- Updates action version from `@beta` to `@v1`
- Migrates `allowed_tools` to `claude_args: --allowedTools`
- Migrates `custom_instructions` to `claude_args: --system-prompt`
- Retains `additional_permissions` and `assignee_trigger` (both still supported in v1)

## Behavior
The action continues to work the same way:
- Triggers on `@claude` mentions in comments, reviews, and issues
- Triggers when assigned to an issue as "claude"
- Allows Claude to run Bash commands
- Allows Claude to read CI results on PRs
- Applies custom instructions for posting concise summaries

Subject: [PATCH 3/8] fix(ci): test failures should fail the build (#3019)

The 'Check if tests exist' step was actually running tests with
continue-on-error: true. If tests failed, it would set has-tests=false
and skip the actual test step, making CI appear green even with failing tests.

Simplified to use 'npm test --if-present' which:
- Runs tests if a test script exists (and fails if tests fail)
- Does nothing and exits 0 if no test script exists
- Removes the need for the complex check logic

Fixes the issue where PR #3014 had failing tests but CI was green.

Subject: [PATCH 4/8] fix(filesystem): convert to modern TypeScript SDK APIs
 (#3016)

* fix(filesystem): convert to modern TypeScript SDK APIs

Convert the filesystem server to use the modern McpServer API instead
of the low-level Server API.

Key changes:
- Replace Server with McpServer from @modelcontextprotocol/sdk/server/mcp.js
- Convert all 13 tools to use registerTool() instead of manual request handlers
- Use Zod schemas directly in inputSchema/outputSchema
- Add structuredContent to all tool responses
- Fix type literals to use 'as const' assertions
- Update roots protocol handling to use server.server.* pattern
- Fix tsconfig to exclude vitest.config.ts

Tools converted:
- read_file (deprecated)
- read_text_file
- read_media_file
- read_multiple_files
- write_file
- edit_file
- create_directory
- list_directory
- list_directory_with_sizes
- directory_tree
- move_file
- search_files
- get_file_info
- list_allowed_directories

The modern API provides:
- Less boilerplate code
- Better type safety with Zod
- More declarative tool registration
- Cleaner, more maintainable code

* fix: use default import for minimatch

minimatch v10+ uses default export instead of named export

* fix(filesystem): use named import for minimatch

The minimatch module doesn't have a default export, so we need to use
the named import syntax instead.

Fixes TypeScript compilation error:
error TS2613: Module has no default export. Did you mean to use
'import { minimatch } from "minimatch"' instead?

Subject: [PATCH 5/8] fix(sequential-thinking): convert to modern TypeScript
 SDK APIs (#3014)

* fix(sequential-thinking): convert to modern TypeScript SDK APIs

Convert the sequential-thinking server to use the modern McpServer API
instead of the low-level Server API.

Key changes:
- Replace Server with McpServer from @modelcontextprotocol/sdk/server/mcp.js
- Use registerTool() method instead of manual request handlers
- Use Zod schemas directly in inputSchema/outputSchema
- Add structuredContent to tool responses
- Fix type literals to use 'as const' assertions

The modern API provides:
- Less boilerplate code
- Better type safety with Zod
- More declarative tool registration
- Cleaner, more maintainable code

* fix: exclude test files from TypeScript build

Add exclude for test files and vitest.config.ts to tsconfig

* refactor: remove redundant validation now handled by Zod

Zod schema already validates all required fields and types. Removed
validateThoughtData() method and kept only business logic validation
(adjusting totalThoughts if needed).

* fix(sequentialthinking): add Zod validation to processThought method

The modern API migration removed manual validation from processThought(),
but tests call this method directly, bypassing the Zod validation in the
tool registration layer. This commit adds Zod validation directly in the
processThought() method to ensure validation works both when called via
MCP and when called directly (e.g., in tests).

Also improves error message formatting to match the expected error
messages in the tests.

* refactor: simplify by removing redundant validation

Since processThought() is only called through the tool registration in
production, validation always happens via Zod schemas at that layer.
Removed redundant validation logic from processThought() and updated
tests to reflect this architectural decision.

Changes:
- Remove Zod validation from processThought() method
- Accept ThoughtData type instead of unknown
- Remove 10 validation tests that are now handled at tool registration
- Add comment explaining validation approach

Subject: [PATCH 6/8] fix(memory): convert to modern TypeScript SDK APIs
 (#3015)

* fix(memory): convert to modern TypeScript SDK APIs

Convert the memory server to use the modern McpServer API instead of
the low-level Server API.

Key changes:
- Replace Server with McpServer from @modelcontextprotocol/sdk/server/mcp.js
- Convert all 9 tools to use registerTool() instead of manual request handlers
- Create reusable Zod schemas for Entity and Relation types
- Use Zod schemas directly in inputSchema/outputSchema
- Add structuredContent to all tool responses
- Fix type literals to use 'as const' assertions

The modern API provides:
- Less boilerplate code (removed ~200 lines of schema definitions)
- Better type safety with Zod
- More declarative tool registration
- Cleaner, more maintainable code

* fix: exclude test files from TypeScript build

Add exclude for test files and vitest.config.ts to tsconfig

Subject: [PATCH 7/8] fix(filesystem): address review feedback from #3016
 (#3031)

Address two items from Camila's review:

1. Use blob type for non-image/non-audio media files, restoring the
   original behavior. This matches the previous implementation which
   used blob as the fallback for unknown binary types. Use type
   assertion to satisfy the SDK's type constraints.

2. Reuse ReadTextFileArgsSchema.shape in the deprecated read_file tool
   instead of redefining the schema inline.

Subject: [PATCH 8/8] fix: simplify output schemas for text-only tools and add
 structuredContent

For text-only tool responses, simplify outputSchemas from complex nested
arrays to simple { content: z.string() } format. All tool responses now
include structuredContent matching their outputSchema, fixing MCP protocol
violations when tools had output schemas but no structured content.

This applies to both filesystem and everything servers.
