- During execution: show tool labels, thinking, and text in main message
- After completion: replace main message with only final assistant text
- Post thinking (italic) and text to thread for full audit trail
- Add promise queue to ensure ctx.respond calls execute sequentially
- Add log.logThinking() and log.logResponse() for console output
- Get final text from agent.state.messages instead of tracking
Closes#65
- Footer now displays active git branch after directory path (e.g., ~/project (main))
- Branch detected by reading .git/HEAD directly (fast, synchronous)
- Cache refreshed after each assistant message to detect branch changes
- Handles normal branches, detached HEAD, and non-git repos
Closes#55
Implements ability to include files directly in the initial message using @ prefix.
Features:
- All @file arguments are coalesced into the first user message
- Text files wrapped in <file name="path">content</file> tags
- Images (.jpg, .jpeg, .png, .gif, .webp) attached as base64-encoded attachments
- Supports ~ expansion, relative and absolute paths
- Empty files are skipped silently
- Non-existent files cause immediate error with clear message
- Works in interactive, --print, and --mode text/json modes
- Not supported in --mode rpc (errors with clear message)
Examples:
pi @prompt.md @image.png "Do this"
pi --print @code.ts "Review this code"
pi @requirements.md @design.png "Implement this"
Closes#54
- Added timestamps to each user and assistant message (HH:MM:SS format)
- Fixed text clipping issues with comprehensive word-wrapping CSS
- Improved font selection: ui-monospace, Cascadia Code, Source Code Pro
- Reduced font sizes for more compact display (12px base, down from 14px)
- Added model switch indicators in conversation timeline with subtle background
- Created dedicated Tokens & Cost section showing:
- Cumulative input/output/cache read/write tokens
- Cost breakdown by token type with 4 decimal precision
- Total cost in bold
- Context usage with token count, percentage, and model identification
- Now displays all unique models used during session (not just initial model)
- Made Messages section more compact (reduced gaps, removed redundant fields)
Closes#51Closes#52
- Up/down arrows now navigate visual (wrapped) lines instead of logical lines
- Fixed double cursor display at wrap boundaries
- Added word by word navigation via Option+Left/Right or Ctrl+Left/Right
- Updated README keyboard shortcuts documentation
Closes#61
- Fix line numbers showing incorrect values for edits far from file start
(e.g., 1,2,3 instead of 336,337,338). Skip count was added after displaying
lines instead of before.
- Rewrite splitIntoTokensWithAnsi in pi-tui to preserve whitespace as separate
tokens instead of discarding it. Wrapped lines now maintain proper alignment
and code indentation.
- Update mom README: rename title, remove em-dashes for cleaner prose
- Type @ to fuzzy-search files/folders across project
- Respects .gitignore and skips hidden files
- Pure Node.js implementation using readdir with withFileTypes
- No external dependencies (fd/find) required
- Also optimized Tab completion to use withFileTypes instead of statSync
Based on PR #60 by @fightbulc, reimplemented for performance.
Fixed crash when rendering text containing emojis followed by long content.
The breakLongWord function was iterating over UTF-16 code units instead of
grapheme clusters, causing emojis (surrogate pairs) to be miscounted during
line wrapping. Now uses Intl.Segmenter to properly handle multi-codepoint
characters.
Removed confusing parenthetical that suggested context files aren't loaded when continuing/resuming sessions. They are always freshly loaded from disk at startup - the parenthetical only applied to console logging behavior.
Working Indicator:
- Add '...' to channel messages while mom is processing
- Automatically removed when work completes or stops
- Applies to working message, not status messages
Improved Stop Command:
- Posts separate 'Stopping...' message that updates to 'Stopped'
- Original working message continues updating with tool results
- Clean separation between status and work output
- Properly handles abort during multi-step operations
Clean Stop Reason Handling:
- Agent run() now returns { stopReason } instead of throwing
- Handle 'aborted', 'error', 'stop', 'length', 'toolUse' cases cleanly
- No more exception-based control flow
- Track stopReason from assistant message.stopReason field
New SlackContext Methods:
- replaceMessage() - replace message text instead of appending
- setWorking() - add/remove working indicator
- Improved context tracking for stop command updates
Major improvements to mom's logging and cost reporting:
Centralized Logging System:
- Add src/log.ts with type-safe logging functions
- Colored console output (green=user, yellow=mom, dim=details)
- Consistent format: [HH:MM:SS] [context] message
- Replace scattered console.log/error calls throughout codebase
Usage Tracking & Cost Reporting:
- Track tokens (input, output, cache read/write) and costs per run
- Display summary at end of each run in console and Slack thread
- Example: 💰 Usage: 12,543 in + 847 out (5,234 cache read) = $0.0234
Prompt Caching Optimization:
- Move recent messages from system prompt to user message
- System prompt now mostly static (only changes with memory files)
- Enables effective use of Anthropic's prompt caching
- Significantly reduces costs on subsequent requests
Model & Cost Improvements:
- Switch from Claude Opus 4.5 to Sonnet 4.5 (~40% cost reduction)
- Fix Claude Opus 4.5 cache pricing in ai package (was 3x too expensive)
- Add manual override in generate-models.ts until upstream fix merges
- Submitted PR to models.dev: https://github.com/sst/models.dev/pull/439
UI/UX Improvements:
- Extract actual text from tool results instead of JSON wrapper
- Cleaner Slack thread formatting with duration and labels
- Tool args formatting shows paths with offset:limit notation
- Add chalk for colored terminal output
Dependencies:
- Add chalk package for terminal colors
- Add MEMORY.md files for persistent working memory
- Global memory: workspace/MEMORY.md (shared across channels)
- Channel memory: workspace/<channel>/MEMORY.md (channel-specific)
- Automatically loaded into system prompt on each request
- Enhance JSONL log format with ISO 8601 dates
- Add 'date' field for easy grepping (e.g., grep '"date":"2025-11-26"')
- Migrated existing logs to include date field
- Improve log query efficiency
- Add jq query patterns to prevent context overflow
- Emphasize limiting NUMBER of messages (10-50), not truncating text
- Show full message text and attachments in queries
- Handle null/empty attachments with (.attachments // [])
- Optimize system prompt
- Add current date/time for date-aware operations
- Format recent messages as TSV (43% token savings vs raw JSONL)
- Add efficient query examples with both JSON and TSV output
- Enhanced security documentation
- Add prompt injection risk warnings
- Document credential exfiltration scenarios
- Provide mitigation strategies
In -p, --mode json, and --mode rpc modes, don't print informational
messages like 'Loaded project context from:' or model restore messages.
Only the actual output should be printed.
BREAKING CHANGE: Passing a prompt on the command line now starts interactive
mode with the prompt pre-submitted, instead of exiting after completion.
Use --print or -p to get the previous non-interactive behavior.
- Add --print / -p flag for non-interactive mode
- Update runInteractiveMode to accept initial messages
- Update README documentation
- Fix Model Selection Priority docs to include --models scope
When pressing Enter on a highlighted slash command suggestion (e.g., typing
`/mod` with `/model` highlighted), the completion is now applied before
submitting. Previously, the partial text was submitted instead of the
selected command.
Fixes#49
PR #47 enhancements:
- Add thinking level syntax to --models (e.g., --models sonnet:high,haiku:low)
- First model in scope used as initial model when starting new session
- Auto-apply thinking level when cycling models with Ctrl+P
- Save both model and thinking to session AND settings for persistence
- Simplify UX by removing autoThinkingDisabled flag
- Fix model matching to prioritize exact matches over partial
- Support provider/modelId format (e.g., openrouter/openai/gpt-5.1-codex)
Issue #45:
- Add --thinking CLI flag to set thinking level directly
- Takes highest priority over all other thinking level sources
Closes#45
