Version 1.0.91

What: Added native support for grep and rg (ripgrep) commands within Claude's secure sandbox How to use:

# Search for patterns in files
grep "TODO" src/*.js
rg "function.*async" --type js

Details:

• Both commands are treated as read-only operations
• Added to command descriptors and safe commands list
• Integrates with existing path restriction framework
• Eliminates need for shell execution for basic search operations

What: New security feature that detects attempts to hide malicious command flags using quotes Implementation: New ML6 function at archive/pretty/pretty-v1.0.91.js:374835 How it works:

# These patterns will now trigger security prompts:
rm "-rf" /     # Quoted flag detected
ls "-"la       # Obfuscated flag pattern detected

Details:

• Analyzes command arguments for suspicious quoting patterns
• Prevents sophisticated command injection attempts
• Echo command exempted from checks as inherently safe
• Part of the enhanced command validation pipeline

What: Pre-configured workflow templates for Claude Code CI/CD integration Implementation: Two new templates added:

• e_B template for claude.yml workflow
• AxB template for claude-review.yml workflow

Details:

• Responds to @claude mentions in issues and PR comments
• Uses production anthropics/claude-code-action@v1 (upgraded from beta)
• Includes proper permissions and trigger configurations
• Supports both manual triggers and automatic code review

What: New shimmer and color interpolation animations for improved visual feedback Implementation: New animation functions yN0, xN0, bN0, fN0 at archive/pretty/pretty-v1.0.91.js:398709-398954 Details:

• RGB color interpolation for smooth transitions
• Character-by-character glimmer effects
• Sine-wave opacity for natural pulsing animations
• Enhanced visual feedback during tool operations

What: Status spinner now displays the activeForm field from in-progress todos Implementation: Removed feature flag MQ("false") at archive/pretty/pretty-v1.0.91.js:398916-398919 How it works:

• When a todo is marked as "in_progress", the spinner shows the activeForm text + "…"
• Example: "Fixing authentication bug…" instead of generic loading text
• Provides contextual progress feedback using present continuous tense

Details:

• Feature was implemented behind a disabled flag in v1.0.90
• Flag removal in v1.0.91 made the display unconditional
• Completes the TodoWrite enhancement that began with schema changes in v1.0.89

What: Automatic detection and reporting of Node.js runtime warnings Implementation: New UN2 function and warning patterns at archive/pretty/pretty-v1.0.91.js:356268 Details:

• Specifically monitors MaxListenersExceededWarning events
• Distinguishes between internal vs external warnings
• Tracks occurrence counts for telemetry
• Optional debug logging with CLAUDE_DEBUG=true

What: Enhanced OAuth callback server with dynamic port allocation Details:

• Server class restructured from zL0 to rL0
• Now starts on port 0 for OS-assigned available ports
• Prevents port conflicts during authentication flows
• Improved error handling and cleanup with removeAllListeners()

What: Structured OAuth error classes and better error recovery Details:

• New error classes: cI, ak1, Ve, Ke for different OAuth failure modes
• Enhanced metadata discovery with fallback mechanisms
• Better handling of various OAuth server implementations
• More robust token exchange processes

What: Fixed null pointer exception in command argument filtering Details:

• Changed filter condition from !B.startsWith("-") to !B?.startsWith("-")
• Prevents crashes when processing commands with null/undefined arguments
• Improves robustness of command parsing pipeline

The following were already present in v1.0.90 and are not new features:

• Statsig Analytics Integration: Full analytics infrastructure was already implemented
• OAuth Authentication Core: Basic OAuth functionality existed, only reliability improvements added
• Command Security Framework: Core security mechanisms were in place, only obfuscation detection added

• File structure similarity: 99.1% between versions
• Total changes: 74 additions, 16 deletions, 17 modifications
• Primary focus on security, reliability, and user experience refinements
