Implements a pipeline that orchestrates 7 g3 agents in sequence:
1. euler - dependency graph and hotspots analysis
2. breaker - whitebox exploration and edge-case discovery
3. hopper - deep testing and regression integrity
4. fowler - refactoring to deduplicate and reduce complexity
5. carmack - in-place rewriting for readability and concision
6. lamport - human-readable documentation and validation
7. huffman - semantic compression of memory
Features:
- Commit cursor tracking (--from flag to set starting point)
- Crash recovery (resumes from last incomplete stage)
- Git worktree isolation for all pipeline work
- Visual pipeline display with status icons
- Summary generation saved to .g3/sessions/sdlc/
- Pipeline state persisted to analysis/sdlc/pipeline.json
CLI:
- studio sdlc run [-c N] [--from COMMIT]
- studio sdlc status
- studio sdlc reset
Also adds huffman agent to embedded agents list.
- 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
- Start g3 in plan mode with ' >>' prompt and welcome message
- Add is_approval_input() to detect 'approve', 'a', 'yes', etc. and misspellings
- Allow trailing punctuation (!, ., ,) on approval words
- Call plan_approve tool directly without LLM when approval detected
- Add synthetic assistant message after approval for LLM context
- Exit plan mode after successful approval, return to 'g3>' prompt
- CTRL-D in plan mode exits plan mode first, then exits g3
- /plan command enters plan mode and shows welcome message
- Agent mode (--agent) does not start in plan mode
- Add CommandResult enum to signal plan mode entry from commands
- Fix vertical bar continuation: │ continues all the way down, only the
very last sub-line (boundary of last item) gets └
- Add visual gap before plan file path and change 📄 to ->
- Dedent file path to align with tree root
- Fix plan_approve to use proper compact tool format (was missing from
is_compact_tool matches! in print_tool_compact, causing it to fall
through to regular output with | prefix)
- Update command matching from /feature to /plan in commands.rs
- Update help text, usage message, and example
- Update workspace memory references
- /feature is no longer recognized (completely removed)
Fixes two bugs in the input formatter:
1. Single/double quote regex now requires word boundaries:
- Contractions like it's, don't, won't no longer trigger highlighting
- Only properly quoted text like 'special' or "hello" gets cyan
- Mixed input like "it's a 'test' case" only highlights 'test'
2. Visual line calculation fix for exact terminal width:
- When text exactly fills terminal width, cursor wraps to next line
- Added +1 adjustment to account for this edge case
- Extracted calculate_visual_lines() for testability
Added 9 new tests covering all edge cases.
Plan tools (plan_read, plan_write) now display with elegant tree-style
formatting similar to the old todo_write UI:
- State indicators: □ (todo), ◐ (doing), ■ (done), ⊘ (blocked)
- Tree prefixes (├/└) for items with child details
- Strikethrough for completed items
- Shows touches and all three checks (happy/negative/boundary)
- Displays plan file path link at the end
plan_approve uses compact single-line format like read_file:
- Shows approval status and revision number
- Handles already-approved and error cases
Changes:
- Add print_plan_compact() to UiWriter trait with default impl
- Implement print_plan_compact() in ConsoleUiWriter
- Call print_plan_compact() from execute_plan_read/write
- Add plan_read/plan_write to is_self_handled_tool()
- Add plan_approve to is_compact_tool() with format_plan_approve_summary()
- Add serde_yaml dependency to g3-cli
Plan Mode is a cognitive forcing system that requires reasoning about:
- Happy path
- Negative case
- Boundary condition
New tools:
- plan_read: Read current plan for session
- plan_write: Create/update plan with YAML content (validates structure)
- plan_approve: Mark current revision as approved
New command:
- /feature <description>: Start Plan Mode for a new feature
Plan schema requires:
- plan_id, revision, approved_revision
- items with id, description, state, touches, checks (happy/negative/boundary)
- evidence and notes required when marking items done
Verification:
- plan_verify() called automatically when all items are done/blocked
Removed:
- todo_read, todo_write tools
- todo.rs module and related tests
Allow users to view research reports directly from the CLI:
- /research - List all research tasks (unchanged)
- /research <id> - View the full report for a specific research task
- /research latest - View the most recent completed research report
Report display includes query, status, elapsed time, and full content.
When background research completes, g3 now immediately prints a status
message instead of waiting for the next user interaction:
- Added ResearchCompletionNotification and broadcast channel to
PendingResearchManager for push-based notifications
- Added spawn_research_notification_handler() in interactive mode that
listens for completions in a background task
- When idle (at prompt): clears line, prints status, reprints prompt
- When busy (processing): prints status inline (interleaving is fine)
- Added G3Status::research_complete() for consistent formatting
- Added enable_research_notifications() method to Agent
Output format: "g3: 1 research report ... [done]"
Fixes three bugs in the input formatter introduced in 4e16942:
1. Bug 2 & 3 (missing newline, line duplication):
- Changed print! to println! to add trailing newline
- Calculate visual lines based on terminal width instead of
logical line count, fixing duplication for wrapped lines
2. Bug 1 (^M on non-interactive prompts):
- Added TTY check to skip formatting when stdout is not a terminal
- Prevents terminal state corruption for stdin prompts
The research tool now spawns the scout agent in a background tokio task
and returns immediately with a research_id placeholder. This allows the
agent to continue working while research runs (30-120 seconds).
Key changes:
- New PendingResearchManager for tracking async research tasks
- research tool returns immediately with placeholder containing research_id
- research_status tool to check progress of pending research
- Auto-injection of completed research at natural break points:
- Start of each tool iteration (before LLM call)
- Before prompting user in interactive mode
- /research CLI command to list all research tasks
- Updated system prompt to explain async behavior
The agent can:
- Continue with other work while research runs
- Check status with research_status tool
- Yield turn to user if results are critical before continuing
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()
- Add GeminiProvider with streaming and native tool calling
- Support gemini-2.5-pro, gemini-2.0-flash, gemini-1.5-pro/flash models
- Model-specific context window detection (1M-2M tokens)
- Message conversion: assistant -> model role mapping
- System messages extracted to system_instruction field
- Tool schema conversion with functionCall/functionResponse parts
- SSE streaming with JSON array buffer parsing
- 8 unit tests for conversion and parsing logic
- Register provider in g3-core and validate in g3-cli
- Use global OnceLock for llama.cpp backend to prevent BackendAlreadyInitialized error
- Suppress verbose llama.cpp stderr logging during model loading
- Fix provider validation to accept "embedded.name" format (extract type before dot)
Both multiline and single-line input paths in interactive.rs had identical
code for:
- Template processing (process_template)
- Task execution (execute_task_with_retry)
- Auto-memory reminder with error handling
Extracted to a single execute_user_input() helper function that handles
all three steps. This eliminates code-path aliasing where the two paths
could drift over time.
File reduced from 401 to 393 lines (-2%).
All 106 g3-cli tests pass.
Agent: fowler
Convert remaining ✅ emoji status messages in g3-cli to use the
consistent G3Status formatting system:
- accumulative.rs: 'autonomous run ... [done]'
- commands.rs /clear: 'clearing session ... [done]'
- commands.rs /readme: 'reloading README ... [done/failed/error]'
- commands.rs /unproject: 'unloading project ... [done]'
This provides a consistent 'g3: action ... [status]' format across
all CLI status messages.
Implement highlight_prompt() in G3Helper to colorize the project portion
of the prompt in blue. This uses rustyline's proper mechanism for ANSI
codes in prompts, which correctly handles cursor positioning.
Prompt 'butler | finances> ' now shows '| finances>' in blue.
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.
Remove duplicate logging initialization in agent_mode.rs. Logging is already
initialized in run() before agent mode is dispatched. The duplicate
tracing_subscriber::fmt::layer() was interfering with rustyline's terminal
state, breaking tab completion.
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.
Update test assertions to match new heading color scheme:
- H1: bold pink (\x1b[1;95m) instead of bold magenta
- H2: purple/magenta (\x1b[35m) - unchanged
- H3: cyan (\x1b[36m) instead of magenta
Warnings fixed:
- Remove unused 'warn' import from retry.rs
- Prefix unused 'output' param with underscore
- Prefix unused 'rel_start' with underscore
- Add #[allow(dead_code)] to G3Status::info()
Message format tweaked per feedback:
- 'g3: model overloaded [error]' (no attempt info)
- 'g3: retrying in 2.2s (1/3) ... [done]' (attempt info moved here)
- Handle empty error message in Status::Error to show just '[error]'
Agent prompt files (both workspace agents/<name>.md and embedded)
now support template variables like {{today}}.
This allows agent definitions to include dynamic content:
# My Agent
Today is {{today}}. Your mission is...
