Supports {{var}} syntax for variable substitution in included prompt files.
Currently supported variables:
- {{today}}: Current date in ISO format (YYYY-MM-DD)
Unknown variables trigger a warning and are left unchanged.
- Add template.rs module with process_template() function
- Integrate template processing into read_include_prompt()
- Add comprehensive tests for template processing
- 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
Agent: fowler
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
The --acd flag was being checked AFTER the agent mode early return,
so it was never applied when running with --agent.
Fix: Pass acd_enabled parameter to run_agent_mode() and call
agent.set_acd_enabled(true) when the flag is set.
Always shows at most 8 sessions in tab completion, sorted by newest first.
This applies whether the user types /resume <TAB> or /resume abc<TAB>.
Implementation:
- list_sessions() returns all sessions sorted by mtime (newest first)
- Completion filters by prefix, then takes first 8 matches
Phase 2 of tab completion: semantic completion for session IDs.
Features:
- /resume <TAB> lists all available sessions from .g3/sessions/
- /resume abc<TAB> filters to sessions starting with 'abc'
- Gracefully returns empty if .g3/sessions/ doesn't exist
Implementation:
- Added list_sessions() helper method to G3Helper
- Added Case 4 in complete() for /resume command
- Updated module docs to reflect new capability
Tests:
- test_resume_completion_lists_sessions - verifies listing and filtering
- test_resume_completion_graceful_no_panic - verifies no crash without sessions dir
Verifies that tab completion correctly ignores:
- Bare quotes: "<TAB> - no path prefix, no completion
- Quoted non-paths: "hello world<TAB> - not a path, no completion
- Quoted text without path prefix: "foo<TAB> - no completion
Also fixes test placement (moved tests inside mod tests block)
Edge cases now handled:
1. Unclosed quotes: "~/My <TAB> - completes paths inside quotes
2. Backslash escapes: ~/My\ <TAB> - unescapes before completing
3. Closed quotes: "~/My Files/"<TAB> - works correctly
Key changes:
- extract_word() now tracks backslash escapes (prev_was_backslash)
- is_path_prefix() strips leading quotes before checking
- Added strip_quotes() and unescape_path() helper methods
- complete() now:
- Strips quotes and unescapes paths before calling FilenameCompleter
- Re-wraps completions in quotes or escapes as appropriate
- Preserves user's quoting style (double vs single quotes)
- Uses backslash escapes if user was already using them
Tests added:
- test_actual_completion_with_quotes - verifies all three edge cases
Path completion now works for:
- ./<TAB> - current directory
- ../<TAB> - parent directory
- ~/<TAB> - home directory
- /<TAB> (not at start of line) - root directory
Command completion (/<TAB>) only triggers at the start of the line.
If no command matches, falls through to path completion (e.g., /etc).
Quote-aware word extraction handles paths with spaces:
- "~/My Files/<TAB>" works correctly
Added tests for:
- Path prefix detection
- Word extraction with quotes
- Command vs path disambiguation
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.
Two cosmetic bugs fixed:
1. JSON inside code fences was being filtered - now tracks fence state
and passes through all content inside ``` ... ``` blocks
2. Indented JSON was being filtered - now recognizes that real tool
calls are never indented, so indented JSON is always documentation
Changes:
- Added in_code_fence and fence_buffer fields to FilterState
- Added track_code_fence() to detect ``` markers (with/without language)
- Added pass_through_char() for content inside code fences
- Modified '{' handling to only filter when no leading whitespace
- Added 4 new unit tests for code fence and indentation cases
- Updated 3 stress tests to expect new (correct) behavior
All 16 filter_json unit tests and 59 stress tests pass.
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
- print_g3_progress now uses print! instead of println!
- print_g3_status completes the line with just the status
- Result: 'g3: compacting session ... [done]' on one line
- 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
Adds blackbox tests to verify:
- --include-prompt option is recognized by CLI parser
- --include-prompt appears in help output
- --no-auto-memory option is recognized by CLI parser
- --no-auto-memory appears in help output
Adds a flag to disable the automatic memory update reminder that runs
at the end of agent mode. Useful when running agents that should not
modify project memory.
- Add read_include_prompt() function to read prompt content from a file
- Update combine_project_content() to accept include_prompt parameter
- Change prompt order: cwd → agents → readme → language → include_prompt → memory
- Add section markers around Project Memory for clearer boundaries
- Add comprehensive tests for include prompt functionality and ordering
Updates lib.rs and agent_mode.rs to read the include prompt file
and pass it through to combine_project_content(). The include prompt
is placed after language prompts but before project memory.
Adds a new CLI flag that allows users to include additional prompt
content from a file. The content is appended to the system prompt
before project memory is loaded.
When --safari was passed, Chrome diagnostics were still running because
--chrome-headless defaults to true. This caused the CLI to hang while
running diagnostics for a browser that wouldn't be used.
Now skip Chrome diagnostics when --safari is explicitly set.
Simplify print_context_thinning to just print the message directly.
The message already contains proper ANSI formatting from context_window.rs.
Removes the flash animation and 'Context optimized successfully' footer.
The response was being printed twice: once during streaming and again
after task completion. Removed the redundant print_smart() call since
streaming already displays the response in real-time.
When running g3 --agent butler, the process title is now "g3 [butler]"
which shows up in ps, Activity Monitor, top, etc.
Uses the proctitle crate for cross-platform support.
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.
The JSON filter only suppresses tool calls at line boundaries. When
"Memory checkpoint: " was printed without a trailing newline, the LLM
response `{"tool": "remember", ...}` appeared on the same line and
leaked through to the UI.
Fix:
- Add trailing newline to "Memory checkpoint:" message
- Reset JSON filter state before streaming the response
Added test: test_tool_call_not_at_line_start_passes_through
Documents the filter behavior and references the fix location.
- Remove chat from conflicts_with_all for --agent flag
- Add chat parameter to run_agent_mode()
- Run interactive loop instead of single task when --chat is passed
Usage: g3 --agent <name> --chat
The print_todo_compact() function was missing the call to clear the
streaming hint line before printing the final tool output. This caused
the tool name to appear twice when the hint line wasn't cleared:
● todo_read ● todo_read | empty
Added the missing handle_hint(ToolParsingHint::Complete) call to match
the behavior of print_tool_compact().
Agent: carmack
Changes:
- streaming_parser.rs: Unified find_first/last_tool_call_start into single
find_tool_call_start with SearchDirection enum, reducing duplication.
Simplified is_json_invalidated from 45 to 20 lines with clearer logic.
Fixed redundant !escape_next check in find_complete_json_object_end.
- filter_json.rs: Simplified check_tool_pattern from 40 to 24 lines.
Replaced repetitive prefix checks with loop over ["t", "to", "too", "tool"].
Reduced trailing return statements with direct expression returns.
- ui_writer_impl.rs: Added ansi module for duration color constants.
Simplified duration_color function by removing redundant comments.
- language_prompts.rs: Fixed test assertions to match actual prompt content
("obvious, readable Racket" instead of "RACKET-SPECIFIC GUIDANCE").
All 174+ tests pass. No behavior changes.
- Add ToolParsingHint enum (Detected/Active/Complete) for UI feedback
- New UiWriter methods: print_tool_streaming_hint(), print_tool_streaming_active()
- Refactor ConsoleUiWriter state to use atomics in ParsingHintState
- Add tool_call_streaming field to CompletionChunk for provider hints
- Anthropic provider sends streaming hints when tool name detected
- New streaming helpers: make_tool_streaming_hint(), make_tool_streaming_active()
Parser improvements:
- Add is_json_invalidated() to detect false positive tool patterns
- Fix tool result poisoning when file contents contain partial JSON
- Unescaped newlines in strings or prose after JSON invalidates detection
User sees ' ● tool_name |' immediately when tool call starts streaming,
with blinking indicator while args are received.
Rust-specific readability guidance for the carmack agent including:
- let...else example for shallow control flow
- Async: don't block the runtime (tokio::fs, spawn_blocking, Send)
- Visibility: prefer pub(crate), private fields with accessors
- Generics: impl Trait over explicit params, avoid complex where clauses
- Improved iterator guidance: if you need a comment, use a loop
- UTF-8 string slicing warnings
- Ownership/lifetime pragmatism
- Anti-patterns: no macros/typestate/proc-macros unless already in repo
Also adds Rust detection to LANGUAGE_PROMPTS (empty base prompt,
agent-specific prompts handle the guidance).
When running in agent mode (e.g., --agent carmack) in a workspace with
detected languages, inject agent+language-specific prompts from
prompts/langs/<agent>.<lang>.md at the end of the system prompt.
Changes:
- Add AGENT_LANGUAGE_PROMPTS static array for compile-time embedding
- Add get_agent_language_prompt() to look up specific agent+lang combos
- Add get_agent_language_prompts_for_workspace_with_langs() that returns
both content and matched languages for display
- Update agent_mode.rs to inject prompts and show which languages loaded
- Display format: '✓ carmack: racket language guidance'
- Add tests for new functionality
Uses the same detect_languages() mechanism as regular language prompts
to avoid code-path aliasing.
Use try_init() instead of init() for tracing subscriber setup to
gracefully handle cases where a global subscriber is already set.
This fixes a panic in the scout agent subprocess when spawned by the
research tool, where a dependency may have already initialized tracing.

Move initialize_logging() call to run immediately after CLI parsing,
before any mode checks. This ensures the --verbose flag works correctly
in planning mode, which previously bypassed logging initialization.
Previously, planning mode would return early before initialize_logging()
was called, causing verbose output to be silently ignored.
- Add language_prompts module that auto-detects programming languages in workspace
- Scan for language files with depth limit (2) to inject relevant toolchain prompts
- Add prompts/langs/ directory for language-specific markdown files
- Include Racket/raco toolchain guidance as first language prompt
- Update combine_project_content() to accept language_content parameter
- Integrate language detection into main CLI flow and agent mode
- Update project memory with new feature documentation
