Windows: getProjectId() fails due to backslash path separators

[silvioduka]

Bug

On Windows, the getProjectId() function in all three hook files uses cwd.split('/').pop() which doesn't work because Windows uses backslash (\) as path separator.

Affected files:

• hooks/claude/session-start.ts
• hooks/claude/user-prompt.ts
• hooks/claude/curation.ts

Current code:

function getProjectId(cwd: string): string {
  return cwd.split('/').pop() || 'default'
}

Example: When cwd is E:\Code\claude-toolkit, split('/') returns ['E:\Code\claude-toolkit'] — the entire path as one element. So pop() returns the full path instead of just claude-toolkit.

Fix: Use path.basename() which handles both / and \:

function getProjectId(cwd: string): string {
  return require('path').basename(cwd) || 'default'
}

Impact: Memory hooks silently send wrong project IDs on Windows, so memories are never stored/retrieved correctly. The memory server shows 0 memories for projects even after multiple sessions.

Additional Windows Issues Found

While debugging further, I discovered two more issues preventing memory curation on Windows:

2. Bun.stdin.text() hangs on Windows (SessionEnd hook)

The SessionEnd hook calls Bun.stdin.text() which hangs indefinitely on Windows. Claude Code appears to close/not send stdin properly during session shutdown, causing the hook process to wait forever and never reach the fetch() call.

Affected files:

• hooks/claude/session-start.ts
• hooks/claude/user-prompt.ts
• hooks/claude/curation.ts

Evidence:
Debug logging showed the hook was called but execution stopped at Bun.stdin.text() — no subsequent log lines were ever written.

Fix: Wrap stdin read in a Promise.race with a timeout:

const inputText = await Promise.race([
  Bun.stdin.text(),
  new Promise<string>((_, reject) => setTimeout(() => reject(new Error('stdin timeout')), 3000))
])

3. ANTHROPIC_API_KEY required for SDK curation

The documentation suggests Claude Code OAuth is sufficient, but in practice the curation via @anthropic-ai/claude-agent-sdk requires ANTHROPIC_API_KEY to be set as an environment variable. Without it, curateWithSessionResume() and the transcript fallback silently fail with 0 memories extracted.

The server reads this from process.env.ANTHROPIC_API_KEY in serve.ts — users need to set this before starting the server.

Summary of all Windows fixes needed

#	Issue	Fix
1	cwd.split('/').pop() returns full path on Windows	Use require('path').basename(cwd)
2	Bun.stdin.text() hangs on SessionEnd	Add Promise.race with 3s timeout
3	SDK curation silently fails without API key	Document ANTHROPIC_API_KEY requirement

After applying all three fixes, the full pipeline works on Windows: hook fires → stdin parsed → checkpoint sent → server curates → memories stored.

Thanks for the detailed issues, will work on those right now!
