Core library fixes:
- session-manager.js: wrap all statSync calls in try-catch to prevent
TOCTOU crashes when files are deleted between readdir and stat
- session-manager.js: use birthtime||ctime fallback for Linux compat
- session-manager.js: remove redundant existsSync before readFile
- utils.js: fix findFiles TOCTOU race on statSync inside readdir loop
Hook improvements:
- Add 1MB stdin buffer limits to all PostToolUse hooks to prevent
unbounded memory growth from large payloads
- suggest-compact.js: use fd-based atomic read+write for counter file
to reduce race window between concurrent invocations
- session-end.js: log when transcript file is missing, check
replaceInFile return value for failed timestamp updates
- start-observer.sh: log claude CLI failures instead of silently
swallowing them, check observations file exists before analysis
Test fixes:
- Fix blocking hook tests to send matching input (dev server command)
and expect correct exit code 2 instead of 1
utils.js:
- Fix countInFile: enforce global flag on regex to prevent silent
under-counting (match() without /g returns only first match)
- Add 5s timeout to readStdinJson to prevent hooks hanging forever
- Handle EEXIST race condition in ensureDir
- Pre-compile regex patterns in getGitModifiedFiles to avoid N*M
compilations and catch invalid patterns before filtering
- Add JSDoc documentation to all improved functions
session-manager.js:
- Fix getSessionById triple file read: pass pre-read content to
getSessionStats instead of re-reading from disk
- Allow getSessionStats to accept content string directly
session-aliases.js:
- Wrap temp file cleanup in try/catch to prevent cascading errors
check-console-log.js:
- Refactor to use shared utils (isGitRepo, getGitModifiedFiles, log)
instead of raw execSync calls
- Add exclusion patterns for test files, config files, and scripts/
where console.log is intentional
session-end.js:
- Log count of skipped unparseable transcript lines for diagnostics
suggest-compact.js:
- Guard against NaN from corrupted counter files
package-manager.js:
- Remove dead fallbackOrder parameter (unused after #162 fix)
Add a new /sessions command to manage Claude Code session history with
alias support for quick access to previous sessions.
Features:
- List sessions with pagination and filtering (by date, ID)
- Load and view session content and metadata
- Create memorable aliases for sessions
- Remove aliases
- Display session statistics (lines, items, size)
- List all aliases
New libraries:
- scripts/lib/session-manager.js - Core session CRUD operations
- scripts/lib/session-aliases.js - Alias management with atomic saves
New command:
- commands/sessions.md - Complete command with embedded scripts
Modified:
- scripts/lib/utils.js - Add getAliasesPath() export
- scripts/hooks/session-start.js - Show available aliases on session start
Session format support:
- Old: YYYY-MM-DD-session.tmp
- New: YYYY-MM-DD-<short-id>-session.tmp
Aliases are stored in ~/.claude/session-aliases.json with Windows-
compatible atomic writes and backup support.
