- Shows web search capability via simple tool pattern
- Demonstrates how easy it is to extend pi with custom tools
- Clear stance: no background bash execution
- Alternative: use tmux or tterminal-cp
- Link to tterminal-cp repo
- Rationale: long-running commands need proper terminal sessions
Planning:
- Clear stance: no built-in planning mode
- Alternative: write plans to PLAN.md files
- Persists across sessions, can be versioned
- Example provided showing structured approach
Auto-compaction:
- Added alternative: switch to bigger context model (Gemini)
- Can summarize session with larger model mid-session

- Apply proper color coding for added/removed/context lines
- Remove unused generateDiff function
- Match TUI's diff rendering approach
- Remove statusContainer.clear() from clearEditor()
- Loading animation should only be removed when agent finishes
- Ctrl+C once should only clear editor text, not status
- Context files now appended to system prompt
- Added current date/time to system prompt
- Added current working directory to system prompt
- Date/time and cwd placed at end of system prompt
- Updated README to reflect system prompt integration
- Walk up parent directories to load all AGENT.md/CLAUDE.md files
- Load global context from ~/.pi/agent/AGENT.md or CLAUDE.md
- Load order: global → top-most parent → ... → cwd
- Prefer AGENT.md over CLAUDE.md in each directory
- Each context file injected as separate message
- Updated README with detailed documentation
- Sessions are no longer created immediately on startup
- Session files only created after at least 1 user message and 1 assistant response
- Prevents empty session files when agent is launched and immediately quit
- Messages are queued until session is initialized
- Continue/resume modes properly mark sessions as already initialized
Session reconstruction only needs:
- type: 'session' - session metadata
- type: 'message' - conversation history
- type: 'thinking_level_change' - thinking level changes
- type: 'model_change' - model changes
Events like agent_start/end, tool_execution_start/end are not needed for
session reconstruction and only added bloat. This reduces session file size
significantly and speeds up writes.
- text mode: only outputs final assistant message text (default)
- json mode: streams all events as JSON (same as session manager writes)
- rpc mode: JSON output + listens for JSON input on stdin for headless operation
- Suppress informational messages in json/rpc modes
- Add generateDiffString() function in edit tool to create unified diffs with line numbers and 4 lines of context
- Store only the formatted diff string in tool result details instead of full file contents
- Update tool-execution renderer to parse and colorize the diff string
- Filter out message_update events from session saving to prevent verbose session files
- Add markdown nested list and table rendering tests
**Improved output messages:**
1. File fits within limits: Just outputs content (no notices)
2. Lines get truncated: Shows "Some lines were truncated to 2000 characters for display"
3. File doesn't fit limit: Shows "N more lines not shown. Use offset=X to continue reading"
4. Offset beyond file: Shows "Error: Offset X is beyond end of file (N lines total)"
5. Both truncations: Combines both notices with ". " separator
**Comprehensive test coverage:**
- Files within limits (no notices)
- Large files (line truncation)
- Long lines (character truncation)
- Offset parameter
- Limit parameter
- Offset + limit together
- Invalid offset (out of bounds)
- Combined truncations (both notices)
All 17 tests passing ✓
- Default limit of 2000 lines per read
- Maximum line length of 2000 characters (truncates longer lines)
- Add optional offset and limit parameters for pagination
- Show truncation notice with instruction to continue reading
- Plain text output (no line numbers)
Examples:
- `read path/to/file` - reads first 2000 lines
- `read path/to/file offset=2001` - continues from line 2001
- `read path/to/file limit=100` - reads only 100 lines
This prevents extremely large files from overwhelming context.
Changed export success/error messages to match the style used for thinking level changes:
- Use Spacer(1) instead of empty Text for proper blank line spacing
- Use chalk.dim() for success message instead of chalk.green()
- Add left padding (1, 0) to match other system messages
- Removed checkmark/x symbols for cleaner look
Now "Session exported to: filename.html" appears dimmed with proper spacing, just like "Thinking level: off"
**Header improvements:**
- Changed title from "pi coding-agent session" to "pi v{version}"
- Smaller, more compact header (16px instead of 20px)
- Info items now stack vertically with consistent labels (80px width)
- Reduced padding and spacing for cleaner look
- Labels aligned to left, values aligned to baseline
The header is now much less cramped and easier to read.
**Click-to-expand functionality:**
- Truncated tool outputs are now clickable to show full content
- Works for bash (>5 lines), read (>10 lines), write (>10 lines)
- Displays "... (N more lines) - click to expand" hint in cyan
- Smooth toggle between preview and full output
- Cursor changes to pointer on hover
**System prompt and tools display:**
- Added system prompt section with yellow header on dark brownish background
- Shows all available tools with names and descriptions
- Both sections appear before messages for context
- Subtle yellow/brown theme (rgb(60, 55, 40)) that's not too bright
The HTML export now provides better interactivity for large outputs and gives full context about the agent's configuration.
