- Add terminal_width module with get_terminal_width(), clip_line(),
compress_path(), and compress_command() utilities
- Update ConsoleUiWriter to use dynamic terminal width for all tool output
- Tool output lines are clipped to fit without wrapping
- Tool headers use semantic compression (paths preserve filename,
commands clip from right)
- 4-character right margin for visual clarity
- Minimum 40 columns, default 80 when terminal size unavailable
- All truncation is UTF-8 safe (char counting, not byte slicing)
- Add 13 unit tests for terminal width utilities
- Remove the interactive prompt that asked users to resume in-progress sessions
- Remove unused new_session parameter from run_interactive()
- Remove unused info_inline() function from G3Status
- Explicit --resume <session_id> flag still works
- Add --resume CLI flag that conflicts with --new-session
- Add load_continuation_by_id() to load sessions by full or partial ID
- Support loading from latest.json or falling back to session.json
- Handle --resume in both normal and agent modes
- Agent mode validates session belongs to correct agent
Implements the Agent Skills specification (https://agentskills.io) for
portable skill packages that give the agent new capabilities.
Changes:
- Add skills module with SKILL.md parser (YAML frontmatter + markdown body)
- Implement skill discovery from ~/.g3/skills/, config extra_paths, and .g3/skills/
- Generate <available_skills> XML for system prompt injection
- Add SkillsConfig to g3-config with enabled flag and extra_paths
- Wire skills discovery into CLI startup
- Add 29 unit tests for parser, discovery, and prompt generation
- Update README with Agent Skills documentation
Skill locations (priority order):
1. ~/.g3/skills/ (global)
2. Config extra_paths
3. .g3/skills/ (workspace, highest priority)
At startup, g3 scans skill directories and injects a summary into the
system prompt. When the agent needs a skill, it reads the full SKILL.md
using the read_file tool.
When users type prompts in interactive mode, the input is now
reformatted in place with enhanced highlighting:
- ALL CAPS words (2+ chars) become bold green (e.g., FIX, BUG, HTTP2)
- Quoted text ("..." or ...) becomes cyan
- Standard markdown formatting is also supported
New module: input_formatter.rs with 10 unit tests
Integrated into interactive.rs for both single-line and multiline input
- Add CommonFlags struct to group flags that apply across all modes
- Refactor run_agent_mode() to accept CommonFlags instead of individual params
- Add project loading logic for agent chat mode
- Add integration tests for --project with agent mode
This refactor prevents future bugs where new flags work in one mode
but are forgotten in another.
README.md is no longer auto-loaded into the LLM context at startup.
This saves ~4,600 tokens per session while AGENTS.md and memory.md
still provide all critical information for code tasks.
Changes:
- Delete read_project_readme() function
- Remove readme_content parameter from combine_project_content()
- Rename extract_readme_heading() -> extract_project_heading()
- Rename Agent constructors: *_with_readme_* -> *_with_project_context_*
- Update context preservation to only check for Agent Configuration
- Remove has_readme field from LoadedContent
- Update all tests to use new markers and function names
The LLM can still read README.md on-demand via read_file when needed.
Adds a new --project <PATH> flag that loads project files (brief.md,
contacts.yaml, status.md) at startup, similar to the /project command
but WITHOUT auto-executing the project status prompt.
Changes:
- Add --project flag to cli_args.rs
- Add load_and_validate_project() helper in project.rs (shared by both
--project flag and /project command)
- Modify run_interactive() to accept optional initial_project parameter
- Wire up --project in lib.rs to load project before interactive mode
- Refactor /project command to use shared helper (reduces duplication)
- Add 4 new tests for load_and_validate_project()
Rename all references from "Project Memory" to "Workspace Memory" to avoid
future conflation if a "project" concept is introduced later.
Changes:
- Rename read_project_memory() -> read_workspace_memory()
- Update all prompts, tool descriptions, and comments
- Update header parsing in memory.rs to use "# Workspace Memory"
- Update display detection for "=== Workspace Memory ==="
- Update documentation and analysis/memory.md
11 files changed, ~36 occurrences updated.
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

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.
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.
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.
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.
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.
- 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
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
• Agent prompts are now embedded within the g3 binary
• README.md - Added new "Agent Mode" section documenting:
• All 7 built-in agents with their focus areas
• Usage examples (--list-agents, --agent <name>)
• How to create custom workspace agents
Behavior
1. Workspace agents take priority - If agents/<name>.md exists in the workspace, it's used
2. Embedded fallback - If no workspace agent exists, the embedded version is used
3. Portability - g3 binary now works on any repo without needing the agents/ directory
4. Discoverability - g3 --list-agents shows all available agents and their source
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.
- Move run_flock_mode() to autonomous.rs (parallel execution mode belongs with autonomous code)
- Move initialize_logging() to utils.rs (utility function with simple bool parameter)
- lib.rs reduced from 274 to 216 lines
No behavior changes. All 28 unit tests pass.

The LLM often hallucinates incorrect paths like /Users/jnbrymn/GitHub/g3
when the actual working directory is different. This causes wasted tokens
and failed commands as the LLM tries cd commands that fail.
Fix: Add the current working directory to the combined project content
that gets injected into the context at startup. This appears as:
📂 Working Directory: /actual/path/to/workspace
This is prepended before AGENTS.md, README.md, and project memory,
so the LLM knows the correct path from the start.
Implement compact display format for read_file, write_file, str_replace, and shell:
- read_file/write_file/str_replace: Single line with dimmed summary and timing
Format: ● tool_name | path [range] | summary | tokens ◉ time
- shell: Two-line format with command header and dimmed output
Format: ● shell | command
└─ output (N lines) | tokens ◉ time
Changes:
- Add print_tool_compact() method to UiWriter trait
- Add is_shell_compact state tracking in ConsoleUiWriter
- Add format_write_file_summary() and format_str_replace_summary() helpers
- Fix duplicate response output by checking if response is empty before printing
- Add finish_streaming_markdown() call before return to flush markdown buffer
Consolidate duplicated logic into canonical shared functions:
- Extract load_config_with_cli_overrides() to utils.rs
- Was duplicated in lib.rs and accumulative.rs with subtle differences
- lib.rs version had Chrome diagnostics + provider validation
- accumulative.rs version was missing both
- Now all callers use the complete canonical implementation
- Extract combine_project_content() to project_files.rs
- Was duplicated inline in lib.rs and agent_mode.rs
- Simplified implementation using iterator flatten
- Added unit tests for all cases
This eliminates drift risk where the duplicated implementations
could diverge over time (accumulative.rs was already missing
Chrome diagnostics and provider validation).

ACD (Aggressive Context Dehydration) fixes:
- Fixed dehydrate_context() to extract turn summary from context window
instead of using the passed-in final_response (which contained only
the timing footer, not the actual LLM response)
- Removed final_response parameter from dehydrate_context() since it
now self-extracts the last assistant message as the summary
- This ensures the actual turn summary is preserved after dehydration,
not just the timing footer
New /dump command:
- Added /dump command to dump entire context window to tmp/ for debugging
- Shows message index, role, kind, content length, and full content
- Available in both console and machine modes
UTF-8 safety:
- Fixed truncate_to_word_boundary() to use character indices instead of
byte indices, preventing panics on multi-byte UTF-8 characters
- Added UTF-8 string slicing guidance to AGENTS.md
Agent: g3
The agent mode header now shows:
- Agent name in uppercase with box art
- Working directory (truncated if too long)
- Status indicators for README, AGENTS.md, and Memory loading
- Task preview if provided
Also exports truncate_for_display and adds truncate_path_for_display
helper functions in project_files module.
Extract three cohesive modules from the monolithic lib.rs (3188 -> 2785 lines):
- metrics.rs (147 lines): Turn metrics tracking and histogram generation
- TurnMetrics struct
- format_elapsed_time() for human-readable durations
- generate_turn_histogram() for performance visualization
- Added unit tests for core functions
- project_files.rs (181 lines): Project file reading utilities
- read_agents_config() for AGENTS.md loading
- read_project_readme() for README detection
- read_project_memory() for .g3/memory.md
- extract_readme_heading() for display
- Added unit tests
- coach_feedback.rs (129 lines): Coach feedback extraction from session logs
- extract_from_logs() main entry point
- Helper functions for log parsing and text extraction
All modules have clear single responsibilities, improved documentation,
and maintain identical behavior to the original inline functions.

Agent mode was only loading README.md but not AGENTS.md or project
memory (.g3/memory.md). This meant agents were missing important
context that normal mode had access to.
Now agent mode uses the same read_agents_config(), read_project_readme(),
and read_project_memory() functions as normal mode, combining all three
into the agent context.
Simplify auto-memory by always enabling it in agent mode instead of
requiring the --auto-memory flag. This makes sense because:
- Agent mode is non-interactive, so blocking is acceptable
- Agents benefit from automatically saving discoveries to memory
- Reduces flag complexity for users
The --auto-memory flag still works for other modes if desired.
The --auto-memory flag was not being passed to run_agent_mode() and
send_auto_memory_reminder() was not being called after agent task
execution.
Changes:
- Pass auto_memory parameter to run_agent_mode()
- Add auto_memory parameter to run_agent_mode() function signature
- Call agent.set_auto_memory(true) when flag is enabled
- Call send_auto_memory_reminder() after execute_task() in agent mode
Adds a new --auto-memory CLI flag that automatically sends a reminder
to the LLM after each turn where tools were called, prompting it to
call the remember tool if it discovered any key code locations.
Changes:
- Add auto_memory field and set_auto_memory() method to Agent
- Add tool_calls_this_turn tracking in execute_tool_in_dir()
- Add send_auto_memory_reminder() that sends reminder after tool use
- Add --auto-memory CLI flag and wire it up in console/machine modes
- Call send_auto_memory_reminder() in single-shot and interactive modes
- Add visible status messages for auto-memory actions
Fixes bug where tool calls were not being tracked when execute_tool_in_dir
was called directly with working_dir=None.
