new Date('YYYY-MM-DD') creates UTC midnight, which in negative UTC offset
timezones (e.g., Hawaii) causes getDate() to return the previous day.
Replaced with new Date(year, month - 1, day) for correct local-time behavior.
Added 15 tests: session-manager datetime verification and edge cases (7),
package-manager getCommandPattern special characters (4), and
validators model/skill-reference validation (4). Tests: 651 → 666.
- session-manager: clamp offset/limit to safe non-negative integers to
prevent negative offset counting from end and NaN returning empty results
- session-aliases: add success field to cleanupAliases return value for
API contract consistency with setAlias/deleteAlias/renameAlias
- session-manager.js: fix getSessionStats path detection to handle
Windows paths (C:\...) in addition to Unix paths (/)
- package-manager.js: add try-catch to setPreferredPackageManager for
consistent error handling with setProjectPackageManager
- validate-hooks.js: extract duplicated hook entry validation into
reusable validateHookEntry() helper
- Update .d.ts JSDoc for both fixes
Bug fixes:
- utils.js: prevent duplicate 'g' flag in countInFile regex construction
- validate-agents.js: handle CRLF line endings in frontmatter parsing
- validate-hooks.js: handle \t and \\ escape sequences in inline JS validation
- session-aliases.js: prevent NaN in date sort when timestamps are missing
- session-aliases.js: persist rollback on rename failure instead of silent loss
- session-manager.js: require absolute paths in getSessionStats to prevent
content strings ending with .tmp from being treated as file paths
New tests (164 total, up from 97):
- session-manager.test.js: 27 tests covering parseSessionFilename,
parseSessionMetadata, getSessionStats, CRUD operations, getSessionSize,
getSessionTitle, edge cases (null input, non-existent files, directories)
- session-aliases.test.js: 40 tests covering loadAliases (corrupted JSON,
invalid structure), setAlias (validation, reserved names), resolveAlias,
listAliases (sort, search, limit), deleteAlias, renameAlias, updateAliasTitle,
resolveSessionAlias, getAliasesForSession, cleanupAliases, atomic write
Also includes hook-generated improvements:
- utils.d.ts: document that readStdinJson never rejects
- session-aliases.d.ts: fix updateAliasTitle type to accept null
- package-manager.js: add try-catch to setProjectPackageManager writeFile
- Fix renameAlias() leaving orphaned newAlias key on save failure,
causing in-memory data corruption with both old and new keys present
- Add sessionPath validation to setAlias() to reject empty/null paths
- Guard getSessionById() against empty string matching all sessions
(startsWith('') is always true in JavaScript)
- Fix suggest-compact.js NaN comparison when COMPACT_THRESHOLD env var
is set to a non-numeric value — falls back to 50 instead of silently
disabling the threshold check
- Sync suggest-compact.js to .cursor/ copy
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.
