ANSI color codes in rustyline prompts cause various issues:
- \x01...\x02 markers break cursor movement
- Separate prefix printing causes gaps or disappearing text
Simplified to plain text prompt: 'butler | finances> '
This ensures reliable cursor positioning and tab completion.
Previously used empty string as readline prompt after printing colored
prefix, which caused cursor positioning issues (large gap between
project name and cursor).
Now the prefix contains 'butler | finances' (colored) and readline
gets '> ' as its prompt, so cursor appears immediately after '> '.
Rustyline's \x01...\x02 markers for ANSI codes didn't work correctly,
causing cursor positioning issues and breaking line editing.
New approach: build_prompt() returns (prefix, prompt) tuple where:
- prefix: colored text printed before readline (contains ANSI codes)
- prompt: plain text passed to readline (no ANSI codes)
This ensures rustyline correctly calculates line length while still
showing the colored project name.
When a project is loaded via /project, the prompt now shows:
agent_name |[project_name]>
where the |[project_name]> part is displayed in blue.
Examples:
- Default: g3>
- With project: g3 |[myapp]>
- Agent mode: butler>
- Agent + project: butler |[myapp]>
The prompt automatically resets when /unproject is called.
Added build_prompt() function with 7 unit tests covering all prompt states.
- Extract handle_command() from interactive.rs to new commands.rs module
(320 lines, 15 match arms for /help, /compact, /thinnify, etc.)
- Fix orphaned tests in completion.rs that were outside mod tests block
- Add #[allow(dead_code)] to with_include_prompt_filename() (used in tests)
- interactive.rs reduced from 595 to 290 lines

Created display.rs module with shared display functions:
- format_workspace_path() / print_workspace_path()
- LoadedContent struct for tracking loaded project files
- print_loaded_status() for status line display
- print_project_heading() for README heading
Updated interactive.rs and agent_mode.rs to use the new module,
eliminating duplicated workspace path formatting and loaded items
status line logic.
Results:
- interactive.rs: 641 → 595 lines (-46)
- agent_mode.rs: 312 → 288 lines (-24)
- New display.rs: 197 lines with 5 unit tests
Agent: fowler
New interactive command: /run <file-path>
- Reads the specified file and executes its content as a prompt
- Supports tilde expansion for home directory paths
- Behaves exactly like pasting the file content into the g3> prompt
- Shows helpful error messages for missing files or empty content
Extract a new g3_status module in g3-cli that provides consistent formatting
for all 'g3:' prefixed system status messages.
Key changes:
- Add G3Status struct with methods for progress, done, failed, error, etc.
- Add Status enum with Done, Failed, Error, Resolved, Insufficient, NoChanges
- Add ThinResult struct in g3-core for semantic thinning data
- Update UiWriter trait with print_thin_result() method
- Refactor context thinning to return ThinResult instead of formatted strings
- Update all callers to use the new centralized formatting
- Session resume/decline messages now use G3Status
- Compaction status messages now use G3Status
This maintains clean separation of concerns: g3-core emits semantic data,
g3-cli handles all terminal formatting and colors.
Output is now a single line:
Session number to resume (Enter to cancel): 1 ... resuming scout_88871653e8e5f4f7 [done]
- Session ID displayed in cyan
- [done] displayed in bold green
- [error: ...] displayed in bold red on failure
- Added print_inline() to SimpleOutput for inline prompts
- Combine session info and resume prompt on one line
- Show result inline after user input (y/n)
- Green '... resuming ... [done]' on successful resume
- Dark grey '... starting fresh' when declining
- Yellow '... failed: <error>' on restore failure
Changes the startup status line to only display items that were
actually loaded, instead of showing dots for missing items.
Before: " · README · AGENTS.md ✓ Memory"
After: " ✓ Memory"
Also adds include prompt to the status line when specified:
" ✓ prompt.md ✓ Memory"
The order matches the load order: README → AGENTS.md → include prompt → Memory
When running g3 --agent <name> --chat:
- Skip per-turn memory checkpoint calls (too onerous)
- Call memory checkpoint once when exiting (Ctrl-D)
When running g3 --agent <name> (single-shot):
- Preserve existing behavior: call memory checkpoint after each turn
This keeps the auto-memory feature useful without being intrusive
in interactive agent sessions.
When running g3 --agent <name> --chat, the output is now minimal:
- Workspace path (-> ~/path)
- Status line (README/AGENTS.md/Memory)
- Context progress bar
- Prompt (g3>)
Skipped in this mode:
- Session resume prompts
- "agent mode | name (source)" header
- "g3 programming agent" welcome
- Provider info display
- Language guidance messages
Added from_agent_mode parameter to run_interactive() to control
whether verbose welcome and session resume are shown.
When users explicitly pass --new-session, they want a fresh session.
Previously g3 would still prompt to resume an existing session.
Now the resume check is skipped entirely when the flag is set.
