* fix(mcp): prevent orphan processes by handling stdin close/end and startup race condition
Three gaps in stdin EOF handling:
1. Startup race: parent can die before `process.stdin.on("end", ...)` is
registered, so the event is missed entirely.
2. Missing "close" event: when pipe is forcibly closed (parent SIGKILL),
"close" fires without "end" on some platforms.
3. Transport layer did not propagate stdin termination to its onclose
callback.
Fixes:
- Check readableEnded/destroyed in start() before registering listeners.
- Register stdin end+close listeners in CompatibleStdioServerTransport.
- Add _closed guard for idempotent close().
- Throw if start() is called after close().
- Add process.stdin.on("close") in server.ts alongside existing handlers.
- Add 5 regression tests.
* fix(mcp): register stdin shutdown before server connect
* feat: configure prettier with pre-commit hook integration
Add prettier, lint-staged, and prettier-plugin-tailwindcss at the repo
root with husky pre-commit hook integration. Moves husky from
gitnexus/ to root package.json for reliable hook installation.
- Root package.json with prepare/format/format:check scripts
- .prettierrc with endOfLine:lf and tailwindStylesheet for TW v4
- .prettierignore excluding fixtures, vendor, generated, *.d.ts, *.md
- .gitattributes enforcing LF line endings for Windows consistency
- Pre-commit hook uses direct node_modules/.bin/ paths (no npx)
* style: apply prettier formatting to entire codebase
One-time bulk format. No logic changes.
Use .git-blame-ignore-revs to skip this commit in git blame.
* chore: add .git-blame-ignore-revs for prettier format commit
* perf: pre-commit hook runs only tests related to staged files
Use vitest --related to scope test execution to tests that import
the changed files, instead of running the full suite on every commit.
* perf: remove vitest from pre-commit hook, keep in CI only
Pre-commit now runs lint-staged + tsc only. Tests run in CI
(ci-tests.yml) where they belong — keeps commits fast.
* ci: add prettier format check to quality workflow
PRs will now fail if code isn't formatted with prettier.
* Fix MCP startup transport compatibility
* Preserve CLI flags in MCP startup fix
* Harden MCP transport error handling
* Harden transport security and improve type safety
Transport hardening:
- Add MAX_BUFFER_SIZE (10 MB) cap to prevent OOM from oversized
Content-Length or unbounded newline-delimited input
- Replace recursive readNewlineMessage with iterative loop to prevent
stack overflow from consecutive empty lines
- Tighten looksLikeContentLength to require 14+ bytes before matching
- Add closed-state guard and error handling to send()
- Simplify processReadBuffer loop to break on error
- Fix loose equality (==) to strict (===)
- Widen constructor param types to ReadableStream/WritableStream
Type safety:
- Constrain createLazyAction generics so export name is validated
against the module's actual exports at compile time
- Use proper type guard instead of lint suppression
- Fix test tsconfig type errors
Regression tests for all hardening fixes (13 tests passing).
