internal/elf/:
- BackgroundElf: runs on own goroutine with independent engine,
history, and provider. No shared mutable state.
- Manager: spawns elfs via router.Select() (picks best arm per
task type), tracks lifecycle, WaitAll(), CancelAll(), Cleanup().
internal/tool/agent/:
- Agent tool: LLM can call 'agent' to spawn sub-agents.
Supports task_type hint for routing, wait/background mode.
5-minute timeout, context cancellation propagated.
Concurrent tool execution:
- Read-only tools (fs.read, fs.grep, fs.glob, etc.) execute in
parallel via goroutines.
- Write tools (bash, fs.write, fs.edit) execute sequentially.
- Partition by tool.IsReadOnly().
TUI: /elf command explains how to use sub-agents.
5 elf tests. Exit criteria: parent spawns 3 background elfs on
different providers, collects and synthesizes results.
- ctrl+o toggles between 10-line truncated and full tool output
- Label shows "ctrl+o to expand" (lowercase)
- Fixed: auto permission mode now sticks — config default was
overriding flag default ("default" → "auto" in config defaults)
SummarizeStrategy: calls LLM to condense older messages into a
summary, preserving key decisions, file changes, tool outputs.
Falls back to truncation on failure. Keeps 6 recent messages.
Tool result persistence: outputs >50K chars saved to disk at
.gnoma/sessions/tool-results/{id}.txt with 2K preview inline.
TUI: /compact command for manual compaction, /clear now resets
engine history. Summarize strategy used by default (with
truncation fallback).
- ❯ flush left for user input, continuation lines indented 2 spaces
- ◆ purple icon for AI responses, continuation indented
- User multiline messages: ❯ first line, indented rest
- Tool output: indented under parent
- System messages: • prefix with multiline indent
- Input area: no extra padding, ❯ at column 0
Switch from textinput to textarea bubble:
- Enter submits message
- Shift+Enter / Ctrl+J inserts newline
- Input area auto-expands from 1 to 10 lines based on content
- Line numbers hidden, prompt preserved
Engine.InjectMessage() appends messages to history without triggering
a turn. When permission mode or incognito changes, the notification
is injected as a user+assistant pair so the model sees it as context.
Fixes: model now knows permissions changed and will retry tool calls
instead of remembering old denials from previous mode.
When permission mode changes (Shift+Tab or /permission), the system
message now says "previous tool denials no longer apply, retry if
asked" — helps the model understand it should re-attempt tools
instead of remembering old denials from conversation history.
- Default permission mode changed from bypass to default
- Removed mode info from status bar (shown on separator line instead)
- Ctrl+I toggles incognito mode
- Incognito mode: amber/yellow separator lines with 🔒 label
overrides permission mode color when active
- Shift+Tab cycles permission modes
Each permission mode has a distinct color:
- bypass: green, default: blue, plan: teal
- accept_edits: purple, auto: peach, deny: red
Top separator line shows mode label on right side in mode color.
Both separator lines (above/below input) colored to match.
Shift+Tab cycling visually changes the line colors.
- Shift+Tab cycles permission modes: bypass → default → plan →
accept_edits → auto → bypass
- /permission <mode> slash command to set specific mode
- Current mode shown in status bar (🛡 bypass)
- Permission checker wired into TUI config
- Fixed: chat content no longer overflows past allocated height.
Lines are measured for physical width and hard-truncated to
exactly the chat area height. Input + status bar always visible.
- Header scrolls with chat (not pinned), only input/status fixed
- Git branch in status bar (green, via git rev-parse)
- Alt screen mode — terminal scrollback disabled
- Mouse wheel + PgUp/PgDown scroll within TUI
- New EventToolResult: tool output as dimmed indented block
- Separator lines above/below input, no status bar backgrounds
Switch to bubbles textinput for proper keyboard handling (space,
cursor, backspace, clipboard all work correctly).
Improved design:
- ❯ user prompt, ◆ assistant prefix, ✗ error prefix
- Word wrapping for long responses
- Separator line between chat and input
- Streaming indicator (● streaming) in status bar
- Better color scheme (lighter purples/blues)
- Welcome message with usage hints
TUI launches when no piped input detected. Features:
- Chat panel with scrollable message history
- Streaming response with animated cursor
- User/assistant/tool/error message styling (purple theme)
- Status bar: provider, model, token count, turn count
- Input with basic editing
- Slash commands: /quit, /clear, /incognito (stub)
- Ctrl+C cancels current turn or exits
Built on charm.land/bubbletea/v2, charm.land/lipgloss/v2.
Session interface decouples TUI from engine via channels.
Pipe mode still works for non-interactive use.
