From b4f68abb571d07a58d28b6928fccd876e70d43b2 Mon Sep 17 00:00:00 2001 From: Ovtcharov Date: Wed, 6 May 2026 11:27:07 -0700 Subject: [PATCH 01/21] =?UTF-8?q?feat(cpp):=20M1=20framework=20upgrades=20?= =?UTF-8?q?=E2=80=94=20ProcessRunner,=20FileIOTools,=20GitTools,=20REPL,?= =?UTF-8?q?=20TUI,=20sessions?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Before: the C++ framework had an agent loop, LLM client, and tool registry but lacked file I/O tools, process execution, interactive REPL, session persistence, and a reactive TUI. Example agents used ad-hoc popen wrappers and blocking getline loops. After: six new reusable framework components that any C++ agent can plug into: - ProcessRunner: cross-platform command execution with timeout, output capping - FileIOTools: file_read, file_write, file_edit, file_search with security policies - GitTools: read-only git status/diff/log/show with shell injection prevention - SessionStore: JSON-based conversation persistence with save/load/resume - ReplRunner: two-thread REPL with slash commands, Ctrl-C cancel, session auto-save - TuiConsole: FTXUI-based reactive console with markdown rendering and streaming Also adds: tool argument schema validation in ToolRegistry, agent cancel support (requestCancel/isCancelled), history() accessor, FTXUI FetchContent in CMake. --- cpp/CMakeLists.txt | 49 +++ cpp/include/gaia/agent.h | 29 ++ cpp/include/gaia/file_tools.h | 70 ++++ cpp/include/gaia/git_tools.h | 69 ++++ cpp/include/gaia/process.h | 78 +++++ cpp/include/gaia/repl.h | 140 ++++++++ cpp/include/gaia/session.h | 99 ++++++ cpp/include/gaia/tool_registry.h | 7 + cpp/include/gaia/tui_console.h | 102 ++++++ cpp/src/agent.cpp | 10 + cpp/src/file_tools.cpp | 394 +++++++++++++++++++++ cpp/src/git_tools.cpp | 281 +++++++++++++++ cpp/src/process.cpp | 580 +++++++++++++++++++++++++++++++ cpp/src/repl.cpp | 376 ++++++++++++++++++++ cpp/src/session.cpp | 334 ++++++++++++++++++ cpp/src/tool_registry.cpp | 58 ++++ cpp/src/tui_console.cpp | 270 ++++++++++++++ cpp/src/tui_markdown.cpp | 290 ++++++++++++++++ cpp/tests/test_file_tools.cpp | 352 +++++++++++++++++++ cpp/tests/test_git_tools.cpp | 237 +++++++++++++ cpp/tests/test_process.cpp | 162 +++++++++ cpp/tests/test_repl.cpp | 342 ++++++++++++++++++ cpp/tests/test_session.cpp | 324 +++++++++++++++++ cpp/tests/test_tui_console.cpp | 173 +++++++++ 24 files changed, 4826 insertions(+) create mode 100644 cpp/include/gaia/file_tools.h create mode 100644 cpp/include/gaia/git_tools.h create mode 100644 cpp/include/gaia/process.h create mode 100644 cpp/include/gaia/repl.h create mode 100644 cpp/include/gaia/session.h create mode 100644 cpp/include/gaia/tui_console.h create mode 100644 cpp/src/file_tools.cpp create mode 100644 cpp/src/git_tools.cpp create mode 100644 cpp/src/process.cpp create mode 100644 cpp/src/repl.cpp create mode 100644 cpp/src/session.cpp create mode 100644 cpp/src/tui_console.cpp create mode 100644 cpp/src/tui_markdown.cpp create mode 100644 cpp/tests/test_file_tools.cpp create mode 100644 cpp/tests/test_git_tools.cpp create mode 100644 cpp/tests/test_process.cpp create mode 100644 cpp/tests/test_repl.cpp create mode 100644 cpp/tests/test_session.cpp create mode 100644 cpp/tests/test_tui_console.cpp diff --git a/cpp/CMakeLists.txt b/cpp/CMakeLists.txt index 75098da36..50e45f942 100644 --- a/cpp/CMakeLists.txt +++ b/cpp/CMakeLists.txt @@ -73,6 +73,21 @@ if(NOT httplib_FOUND) FetchContent_MakeAvailable(httplib) endif() +# FTXUI — reactive TUI framework (optional, gated behind GAIA_BUILD_TUI) +option(GAIA_BUILD_TUI "Build FTXUI-based TUI console" ON) +if(GAIA_BUILD_TUI) + find_package(ftxui QUIET) + if(NOT ftxui_FOUND) + message(STATUS "FTXUI not found -- fetching via FetchContent") + FetchContent_Declare( + ftxui + GIT_REPOSITORY https://github.com/ArthurSonzogni/FTXUI + GIT_TAG v6.1.9 + ) + FetchContent_MakeAvailable(ftxui) + endif() +endif() + # Google Test (unit tests and/or integration tests) if(GAIA_BUILD_TESTS OR GAIA_BUILD_INTEGRATION_TESTS) find_package(GTest QUIET) @@ -103,8 +118,22 @@ add_library(gaia_core src/mcp_client.cpp src/security.cpp src/sse_parser.cpp + src/process.cpp + src/file_tools.cpp + src/git_tools.cpp + src/session.cpp + src/repl.cpp ) +# TUI sources (conditional on FTXUI availability) +if(GAIA_BUILD_TUI) + target_sources(gaia_core PRIVATE + src/tui_console.cpp + src/tui_markdown.cpp + ) + target_compile_definitions(gaia_core PUBLIC GAIA_HAS_TUI=1) +endif() + add_library(gaia::gaia_core ALIAS gaia_core) include(GenerateExportHeader) @@ -163,6 +192,16 @@ if(WIN32) target_link_libraries(gaia_core PRIVATE ws2_32) endif() +# FTXUI (TUI console — optional) +if(GAIA_BUILD_TUI) + target_link_libraries(gaia_core PRIVATE + ftxui::component ftxui::dom ftxui::screen + ) + message(STATUS "GAIA TUI: enabled (FTXUI)") +else() + message(STATUS "GAIA TUI: disabled") +endif() + # HTTPS support — auto-detected.

No way for external tools to interact with GAIA C++ agents. After: complete gaia-bash coding agent with five interfaces: - Interactive TUI (default): FTXUI fullscreen with markdown, streaming, slash cmds - Single query: gaia-bash "write a backup script" - REST API server (--serve): OpenAI-compatible /v1/chat/completions, /v1/tools - MCP stdio server (--mcp): JSON-RPC for Claude Code / OpenCode integration - Pipe mode (--print): stdout-friendly for CI/scripting Agent tools: bash_execute (with shell detection), env_inspect, plus framework tools (file_read/write/edit/search, git_status/diff/log/show). Eval framework: 25 scenarios across 5 categories (script writing, review, tool usage, error handling, POSIX compliance) with ground truth validation and a Python adapter for the gaia eval harness. --- cpp/CMakeLists.txt | 30 + cpp/agents/bash/api_server.cpp | 539 +++++++++++++++ cpp/agents/bash/api_server.h | 58 ++ cpp/agents/bash/bash_agent.cpp | 105 +++ cpp/agents/bash/bash_agent.h | 38 ++ cpp/agents/bash/bash_tools.cpp | 262 ++++++++ cpp/agents/bash/bash_tools.h | 64 ++ cpp/agents/bash/eval/bash_eval_adapter.py | 357 ++++++++++ cpp/agents/bash/eval/bash_ground_truth.json | 120 ++++ cpp/agents/bash/eval/bash_scenarios.json | 293 ++++++++ cpp/agents/bash/main.cpp | 270 ++++++++ cpp/agents/bash/mcp_server.cpp | 282 ++++++++ cpp/agents/bash/mcp_server.h | 67 ++ docs/cpp/bash-agent.mdx | 510 ++++++++++++++ docs/docs.json | 1 + docs/plans/bash-agent.mdx | 697 ++++++++++++++++++++ 16 files changed, 3693 insertions(+) create mode 100644 cpp/agents/bash/api_server.cpp create mode 100644 cpp/agents/bash/api_server.h create mode 100644 cpp/agents/bash/bash_agent.cpp create mode 100644 cpp/agents/bash/bash_agent.h create mode 100644 cpp/agents/bash/bash_tools.cpp create mode 100644 cpp/agents/bash/bash_tools.h create mode 100644 cpp/agents/bash/eval/bash_eval_adapter.py create mode 100644 cpp/agents/bash/eval/bash_ground_truth.json create mode 100644 cpp/agents/bash/eval/bash_scenarios.json create mode 100644 cpp/agents/bash/main.cpp create mode 100644 cpp/agents/bash/mcp_server.cpp create mode 100644 cpp/agents/bash/mcp_server.h create mode 100644 docs/cpp/bash-agent.mdx create mode 100644 docs/plans/bash-agent.mdx diff --git a/cpp/CMakeLists.txt b/cpp/CMakeLists.txt index 50e45f942..e6fa4b378 100644 --- a/cpp/CMakeLists.txt +++ b/cpp/CMakeLists.txt @@ -214,6 +214,36 @@ else() message(STATUS "GAIA SSL: not available (HTTP only)") endif() +# --------------------------------------------------------------------------- +# gaia-bash agent binary +# --------------------------------------------------------------------------- +option(GAIA_BUILD_BASH_AGENT "Build the gaia-bash coding agent" ON) +if(GAIA_BUILD_BASH_AGENT) + add_executable(gaia-bash + agents/bash/main.cpp + agents/bash/bash_agent.cpp + agents/bash/bash_tools.cpp + agents/bash/api_server.cpp + agents/bash/mcp_server.cpp + ) + target_include_directories(gaia-bash PRIVATE + ${CMAKE_CURRENT_SOURCE_DIR}/agents/bash + ) + target_link_libraries(gaia-bash PRIVATE gaia::gaia_core) + + # API server needs httplib (already a dependency of gaia_core but PRIVATE) + if(httplib_FOUND) + target_link_libraries(gaia-bash PRIVATE httplib::httplib) + else() + target_include_directories(gaia-bash SYSTEM PRIVATE + $) + endif() + if(OpenSSL_FOUND) + target_compile_definitions(gaia-bash PRIVATE CPPHTTPLIB_OPENSSL_SUPPORT) + target_link_libraries(gaia-bash PRIVATE OpenSSL::SSL OpenSSL::Crypto) + endif() +endif() + # --------------------------------------------------------------------------- # Examples # --------------------------------------------------------------------------- diff --git a/cpp/agents/bash/api_server.cpp b/cpp/agents/bash/api_server.cpp new file mode 100644 index 000000000..7376319fb --- /dev/null +++ b/cpp/agents/bash/api_server.cpp @@ -0,0 +1,539 @@ +// Copyright(C) 2025-2026 Advanced Micro Devices, Inc.

This makes it easier for smaller local models to excel compared to general-purpose coding. +2. **Tool-heavy workflow** — bash work is inherently about running commands and inspecting output. The agent loop (think → tool → observe → think) maps directly to how developers actually work in a terminal. +3. **Local-first is natural** — sysadmins running scripts on servers often can't send code to cloud APIs. A local agent with zero network dependency is a genuine differentiator. +4. **Proves the C++ framework** — building a real product on `gaia_core` surfaces missing capabilities and validates the architecture before more agents follow. + +--- + +## Recommended LLM + +### Primary: Qwen3-Coder-Next (GGUF) + +| Property | Value | +|---|---| +| Architecture | MoE — 80B total, 3B active per forward pass | +| Context window | 256K tokens | +| SWE-bench Verified | 58.7–70.6% (scaffolding-dependent) | +| Hardware | Single 24GB GPU (RTX 4090 / AMD equivalent) | +| Throughput | ~18–22 tok/s GPU, ~10 tok/s CPU-only (96GB RAM) | +| Format | GGUF via llama.cpp (Lemonade backend) | + +**Why this model:** +- Best overall local coding LLM in 2026 — trained on 800K real GitHub PR scenarios +- Non-reasoning model: no thinking blocks, direct fast answers — ideal for a scripting assistant where latency matters +- Ultra-sparse MoE: consumer-grade hardware delivers Sonnet-class coding quality +- Evaluated on Terminal-Bench (shell scripting, DevOps, system-level programming) +- Strong agentic tool-calling performance with recovery from execution failures + +### Tiered Hardware Options + +| Tier | Model | VRAM | Speed | Quality | +|---|---|---|---|---| +| High | Qwen3-Coder-Next Q4_K_XL | 24GB | ~20 tok/s | Excellent | +| Medium | Qwen 2.5 Coder 32B | 24GB | ~25 tok/s | Very good | +| Budget | Qwen 2.5 Coder 14B | 12GB | ~40 tok/s | Good for simple scripts | +| Minimal | Qwen 2.5 Coder 7B | 8GB | ~60 tok/s | Autocomplete quality | + + +**Model quality vs. tool reliability trade-off:** The C++ framework currently uses text-based tool calling (tools described in the system prompt, LLM returns JSON), not OpenAI-native function calling schemas. This means smaller models (7B, 14B) are more likely to hallucinate tool names or produce malformed JSON. The plan includes mitigations — tool argument validation in M1-P1 and optional native function calling in M1-P4 — but Qwen3-Coder-Next at 3B active params is the minimum for reliable multi-step tool orchestration. + + +--- + +## Goals + +- **Sub-second startup** — native binary, no runtime interpreter +- **Offline-capable** — runs entirely on local hardware via Lemonade Server +- **Bash-specialized** — system prompt, tools, and analysis tuned for shell scripting +- **Claude Code-like TUI** — reactive terminal UI with markdown rendering, streaming tokens, split panes +- **Safe by default** — destructive commands require explicit approval, path validation on all file ops +- **Proves `gaia_core`** — first production CLI agent built on the C++ framework, surfacing and fixing framework gaps + +## Non-Goals + +- **Replacing the Python CodeAgent.** `gaia-code` continues to serve general-purpose coding (Python, TS, web). `gaia-bash` is a complementary domain agent. +- **Supporting every shell.** M2-P1 targets `bash` and `sh`. PowerShell, zsh, fish are future extensions — not blockers. +- **Building a general-purpose terminal emulator.** `gaia-bash` runs inside your existing terminal. It's a TUI application, not a terminal replacement. +- **Remote execution (SSH).** Local-only in this plan. Remote execution via MCP server is a natural follow-up but out of scope. +- **Embedding llama.cpp directly.** Inference goes through Lemonade Server's HTTP API. Direct `libllama` embedding adds complexity without clear benefit (Lemonade handles model lifecycle, GPU scheduling, quantization). +- **Windows PowerShell specialization.** The agent runs on Windows (WSL/Git Bash) but the domain expertise is bash/POSIX, not PowerShell. A separate PowerShell agent would be a different project. + +--- + +## Critical Framework Gaps + +The C++ framework exploration revealed five issues that must be addressed before or during implementation. These are not blockers — they're known work items. + +### Gap 1: Text-Based Tool Calling (No Native Function Calling) + +**Current state:** Tools are formatted as text in the system prompt (`==== AVAILABLE TOOLS ====`), and the agent parses LLM responses for `"tool"` / `"tool_args"` JSON fields with regex fallback. The OpenAI-compatible API request does NOT include a `"tools"` parameter. + +**Risk:** Higher tool-name hallucination with smaller models. No schema validation at the API level. + +**Mitigation:** +1. **M1-P1:** Add JSON schema validation for tool arguments before execution +2. **M1-P4 (optional):** Add native function calling via the OpenAI `"tools"` parameter in `LemonadeClient`, gated behind a capability check (Lemonade Server version / model support) + +### Gap 2: No File I/O Tools + +**Current state:** The C++ framework has no built-in `file_read`, `file_write`, or `file_edit` tools. The Python CodeAgent has `FileIOToolsMixin` but nothing equivalent in C++. + +**Resolution:** Implement as framework-level tools in M1-P1. The `ToolRegistry` mechanism is ready — only the tool callbacks need writing. Path validation already exists in `security.cpp`. + +### Gap 3: Basic TUI (No Reactive UI) + +**Current state:** `CleanConsole` outputs ANSI-colored text via `std::cout`. No cursor control, no screen regions, no interactive widgets. Progress indicators (`startProgress`/`stopProgress`) are no-ops. + +**Resolution:** Build `TuiConsole` on FTXUI in M1-P3. `CleanConsole` becomes the fallback for `--no-tui` / piped output modes. + +### Gap 4: No REPL Architecture + +**Current state:** Existing examples (`wifi_agent`, `health_agent`) use blocking `std::getline()` loops that call `processQuery()` once per input. No session continuity model beyond conversation history. + +**Resolution:** Build `ReplRunner` in M1-P2: +- Two-thread architecture: input thread + agent thread +- Maintains conversation history across queries (already supported by `Agent`) +- Slash command framework with built-in commands + agent-registered extensions +- Ctrl-C cancels current agent run without killing the process + +### Gap 5: No Session Persistence + +**Current state:** Conversation history is in-memory only. Process exits lose everything. + +**Resolution:** Build `SessionStore` in M1-P2. Serialize `conversationHistory_` to `~/.gaia/sessions/.json` on exit, reload on startup with `--resume`. + +--- + +## Architecture + +The system has two layers. The bottom layer is the `gaia_core` framework (Milestone 1) — reusable by any future C++ agent.

M1-P4 is optional and can be parallelized with M2. M2-P1 can start as soon as M1-P1 through M1-P3 are complete. M2-P5 can be parallelized with M2-P2/P3. + +--- + +### Milestone 1: C++ Framework Upgrades (`gaia_core`) + +Everything in this milestone ships as library code in `cpp/include/gaia/` and `cpp/src/`. No bash-specific logic. The validation target is: an existing example agent (e.g. `wifi_agent`) can be refactored to use these new primitives and gain interactive TUI, file I/O, and session persistence for free. + +#### M1-P1: Process Runner + File I/O Tools + +**Scope:** Extract the ad-hoc `runShell()` pattern into a proper library utility and add reusable file I/O tool callbacks. + +**Deliverables:** + +| Component | Files | Description | +|---|---|---| +| `ProcessRunner` | `include/gaia/process.h`, `src/process.cpp` | `run(cmd, timeout, cwd, env)` → `{stdout, stderr, exitCode}`. Cross-platform (popen on POSIX, `_popen`/CreateProcess on Windows). Configurable timeout with SIGKILL/TerminateProcess fallback. Output size cap (default 64KB). | +| `FileIOTools` | `include/gaia/file_tools.h`, `src/file_tools.cpp` | Pre-built tool callbacks: `file_read(path, start?, end?)`, `file_write(path, content)`, `file_edit(path, old_string, new_string)`, `file_search(pattern, path?, content_pattern?)`. All use `validatePath()` from `security.cpp`. Register via `ToolRegistry::registerFileTools()`. | +| `GitTools` | `include/gaia/git_tools.h`, `src/git_tools.cpp` | Read-only git tool callbacks: `git_status()`, `git_diff(path?)`, `git_log(n?)`, `git_show(ref)`. Delegates to `ProcessRunner`. Register via `ToolRegistry::registerGitTools()`. | +| Tool argument validation | `tool_registry.h/cpp` | Validate JSON args against declared `ToolParameter` types (string, int, bool, required/optional) before invoking callback. Reject malformed args with actionable error instead of passing garbage to the tool. | +| Unit tests | `tests/test_process.cpp`, `tests/test_file_tools.cpp`, `tests/test_git_tools.cpp` | Mock filesystem and process execution. | + +**Estimated effort:** 2–3 weeks + +#### M1-P2: REPL Runner + Session Persistence + +**Scope:** A reusable interactive loop class that any agent can plug into, replacing the blocking `std::getline()` pattern in examples. + +**Deliverables:** + +| Component | Files | Description | +|---|---|---| +| `ReplRunner` | `include/gaia/repl.h`, `src/repl.cpp` | Two-thread architecture: input thread (reads user input) + agent thread (runs `processQuery()`). Input accepted while agent is thinking. Ctrl-C cancels current agent run (sets a `cancel_` flag checked in the agent loop), doesn't kill the process. | +| Slash command framework | Built into `ReplRunner` | Register slash commands via `repl.addCommand("/name", callback)`. Built-in commands: `/clear` (reset history), `/help` (list commands), `/model ` (switch model), `/history` (show session). Agent-specific commands (e.g. `/lint`) registered by the agent, not the framework. | +| `SessionStore` | `include/gaia/session.h`, `src/session.cpp` | Serialize/deserialize `conversationHistory_` to `~/.gaia/sessions/.json`. `save(id, history)`, `load(id) → history`, `list() → [{id, timestamp, preview}]`. Supports `--resume ` CLI pattern. | +| Agent cancel support | `agent.h/cpp` | Add `requestCancel()` method and `cancelled_` atomic flag. The agent loop checks this flag between steps and exits early with a partial result. | +| Unit tests | `tests/test_repl.cpp`, `tests/test_session.cpp` | Test command dispatch, session round-trip serialization, cancel semantics. | + +**Estimated effort:** 2–3 weeks + +#### M1-P3: FTXUI Console + Markdown Rendering + +**Scope:** A reactive `OutputHandler` subclass built on FTXUI that any agent can use as a drop-in replacement for `CleanConsole`. + +**Deliverables:** + +| Component | Files | Description | +|---|---|---| +| FTXUI dependency | `CMakeLists.txt` | FetchContent for FTXUI v6.1.9. Optional — `CleanConsole` remains the default when FTXUI is not available (piped output, `--no-tui`). Build gate: `option(GAIA_BUILD_TUI "Build FTXUI-based TUI console" ON)`. | +| `TuiConsole` : `OutputHandler` | `include/gaia/tui_console.h`, `src/tui_console.cpp` | FTXUI fullscreen app implementing the `OutputHandler` interface. Layout: scrollable chat history (top), status bar (model name, token count, step N/M), input area (bottom). Streaming tokens update the chat panel in real-time. Tool approval shows a modal dialog ([Y]es / [N]o / [A]lways). | +| Markdown rendering | `src/tui_markdown.cpp` | Render LLM markdown responses inside FTXUI elements: headings (bold + color), `**bold**`, `` `code` ``, fenced code blocks (bordered, syntax-colored for bash keywords), bullet lists, blockquotes. Built in C++17 — lightweight parser, no cmark dependency. MarkdownFTXUI (C++20) is a future upgrade path, not an M1 dependency. | +| Input component | Integrated in `TuiConsole` | Multi-line input with Enter to submit (Shift+Enter or Ctrl+Enter for newline). Up/down arrow for input history. Paste support. | +| Streaming integration | `tui_console.cpp` | `printStreamToken()` appends to the current chat bubble and triggers FTXUI re-render. `printStreamEnd()` finalizes the bubble. | +| `--no-tui` fallback | `repl.h` | ReplRunner auto-detects piped stdout and falls back to `CleanConsole`. Explicit `--no-tui` flag also forces fallback. | +| Unit tests | `tests/test_tui_console.cpp` | Test rendering logic (markdown parser), not FTXUI screen output. | + +**Estimated effort:** 3–4 weeks + +#### M1-P4: Native Function Calling (Optional) + +**Scope:** Send tools as OpenAI-compatible `"tools"` array in the API request instead of embedding them as text in the system prompt. Gated behind a capability check. + +**Deliverables:** + +| Component | Files | Description | +|---|---|---| +| Tool schema export | `tool_registry.h/cpp` | `formatAsOpenAITools() → json` — export registered tools as an OpenAI `tools` array with JSON Schema parameter definitions. | +| LemonadeClient upgrade | `lemonade_client.h/cpp` | Accept optional `tools` JSON in `chatCompletions()` and `chatCompletionsStreaming()`. Include in request body when non-empty. | +| Response parsing | `json_utils.h/cpp` | Parse OpenAI-style `tool_calls` array in assistant messages (alongside existing text-based fallback). | +| Agent integration | `agent.cpp` | Config flag `useNativeFunctionCalling` (default: false). When enabled, uses schema export + native parsing. Falls back to text-based on error. | +| Capability detection | `lemonade_client.cpp` | Probe Lemonade Server `/health` or `/v1/models` for function calling support. Auto-enable when available. | +| Integration test | `tests/integration/test_function_calling.cpp` | Test with real Lemonade Server + Qwen model. | + + +This phase is **optional** — the text-based approach works and is what ships first. Native function calling is a reliability upgrade that reduces tool hallucinations, especially with smaller models (7B–14B). It can be deferred or parallelized with Milestone 2 work. + + +**Estimated effort:** 2–3 weeks + +--- + +### Milestone 2: Bash Coding Agent (`gaia-bash`) + +Everything in this milestone is bash-domain-specific code. It lives in `cpp/agents/bash/` (or a similar directory), links against `gaia_core`, and produces a standalone `gaia-bash` binary. Framework components from Milestone 1 are consumed, not modified. + +#### M2-P1: Core Agent + Basic TUI + +**Scope:** Functional bash agent with domain tools, FTXUI shell, streaming — the "hello world" that proves M1 works end-to-end. + +**Deliverables:** + +| Component | Description | +|---|---| +| `BashAgent : Agent` | Subclass with `registerTools()` and `getSystemPrompt()`. Registers framework tools (file I/O, git) plus bash-specific tools. | +| Bash system prompt | Expert persona: POSIX-first, `set -euo pipefail`, quoting rules, ShellCheck awareness. | +| `bash_execute` tool | Wraps `ProcessRunner` with bash-specific concerns: shell detection (bash/sh/WSL), shebang injection, output truncation heuristics. CONFIRM policy. | +| `env_inspect` tool | Shell version, PATH, OS info, installed tools detection (`jq`, `shellcheck`, `bats`). ALLOW policy. | +| CLI entry point (`main.cpp`) | Argument parsing: `gaia-bash "query"` (single-shot), `gaia-bash` (interactive), `gaia-bash --print` (piped), `gaia-bash --resume `. | +| REPL integration | Plugs `BashAgent` into `ReplRunner` with `TuiConsole`. | +| Cross-platform shell detection | Detect available shell (bash, sh, WSL, Git Bash) and configure `bash_execute` accordingly. | +| CMake target | `add_executable(gaia-bash ...)` linking `gaia_core`, FTXUI. | +| Unit + integration tests | Mock-LLM tests for all bash tools. Integration test with real Lemonade. | + +**Estimated effort:** 2–3 weeks + +#### M2-P2: Developer Tools + Slash Commands + +**Scope:** ShellCheck, BATS, man pages, and the slash command UX that makes bash work feel native. + +**Deliverables:** + +| Component | Description | +|---|---| +| `script_lint` tool | Run ShellCheck with `-f json1`, parse structured output → severity + line + SC code + fix suggestion. Graceful degradation if ShellCheck not installed. ALLOW policy. | +| `script_test` tool | Create temp sandbox dir, write script + generated BATS test, execute `bats`, capture TAP output, cleanup. CONFIRM policy. | +| `man_lookup` tool | Run `man ` or ` --help`, capture and truncate output. ALLOW policy. | +| `git_commit` tool | Stage files + LLM-generated commit message with preview. CONFIRM policy. | +| Bash slash commands | `/run ` (direct execution), `/lint [file]`, `/test [file]`, `/review [file]`, `/edit ` (open in `$EDITOR`). Registered via `ReplRunner::addCommand()`. | +| Clipboard integration | `clipboard_copy` tool — xclip/pbcopy/wl-copy/win32 `SetClipboardData`. ALLOW policy. | + +**Estimated effort:** 2–3 weeks + +#### M2-P3: Intelligence Layer + +**Scope:** The domain expertise that makes `gaia-bash` more than a wrapper around a generic LLM. + +**Deliverables:** + +| Component | Description | +|---|---| +| Code review engine | Multi-pass LLM analysis: correctness → security → portability → performance → style. Triggered by `/review` or `review this script`. | +| POSIX compliance checker | Flag bashisms (`[[ ]]`, `<<<`, `${var,,}`, arrays) when shebang is `#!/bin/sh`. Suggest portable alternatives. | +| BATS test generation | Given a script, generate test cases covering happy path, error cases, edge cases, exit codes. | +| Dependency detection | Scan `#!/bin/bash` scripts for external tool usage (`jq`, `yq`, `curl`, `awk`, `sed`, `docker`, `kubectl`), check which are on PATH, warn on missing. | +| `bash_background` tool | Run command in background, return PID, `poll(pid)` for output, `kill(pid)` to stop. CONFIRM policy. | +| `process_list` tool | `ps aux` / `tasklist` with grep filtering. ALLOW policy. | +| `cron_inspect` tool | Read `crontab -l`, parse systemd timers. ALLOW policy. | +| `network_check` tool | `ping`, `curl -I`, `dig` with structured output. CONFIRM policy. | +| Snippet templates | Built-in prompt templates for common patterns: argument parsing (`getopts`), error handling (`trap`), logging, parallel execution (`xargs -P`, GNU parallel). | +| Auto-mode | Classify tools as safe (read-only → auto-approve) vs. dangerous (writes, network → require confirmation). Config-driven override. | + +**Estimated effort:** 3–4 weeks + +#### M2-P4: Polish + Distribution + +**Scope:** Production readiness, packaging, docs, CI. + +**Deliverables:** + +| Component | Description | +|---|---| +| Static linking | Single-binary distribution — no shared library dependencies beyond libc/kernel32. | +| `gaia init` integration | Model download for Qwen3-Coder-Next via Lemonade API from C++. First-run setup flow. | +| Performance benchmarks | Startup latency (<100ms target), token throughput, memory footprint. Tracked in CI. | +| Integration tests | End-to-end tests against real Lemonade Server in CI. | +| Documentation | `docs/guides/bash.mdx` — quickstart, tool reference, examples. Update `docs/docs.json`. | +| CI/CD build matrix | Windows MSVC, Linux GCC/Clang, macOS AppleClang. Artifact upload to GitHub Releases. | +| Python bridge | `gaia bash` subcommand in `cli.py` that delegates to the native binary if found on PATH. | + +**Estimated effort:** 2–3 weeks + +#### M2-P5: API Server + MCP Server (Third-Party Integration) + +**Scope:** Expose the bash agent via an HTTP REST API and an MCP server so external tools (Claude Code, OpenCode, custom integrations) can interact with it programmatically. + +**Deliverables:** + +| Component | Description | +|---|---| +| **REST API server** | Built-in HTTP server (cpp-httplib, already a dependency) exposing OpenAI-compatible `/v1/chat/completions` endpoint. Runs on configurable port (default 8200). Supports streaming via SSE. Accepts tool calls in request body. | +| `/v1/chat/completions` | Main endpoint: accepts messages array, routes through BashAgent, returns structured response with tool call results. Streaming mode sends token-by-token SSE events. | +| `/v1/tools` | List all registered bash agent tools with their schemas (name, description, parameters). Read-only. | +| `/v1/tools/{name}` | Execute a specific tool directly (bypass LLM). Useful for external orchestrators that want to call `bash_execute` or `file_read` without going through the agent loop. | +| `/health` | Health check endpoint returning agent status, model info, and tool count. | +| `/sessions` | CRUD for sessions: `GET /sessions` (list), `POST /sessions` (create), `GET /sessions/{id}` (load), `DELETE /sessions/{id}` (remove). | +| `--serve` CLI flag | Start the API server: `gaia-bash --serve [--port 8200]`. Runs instead of the interactive TUI. | +| **MCP server (stdio)** | Expose the bash agent as an MCP tool server over stdio transport. External agents (e.g. Claude Code, OpenCode) can connect via `{"command": "gaia-bash", "args": ["--mcp"]}` in their MCP config. | +| MCP `tools/list` | Returns all bash agent tools as MCP tool definitions (name, description, inputSchema). | +| MCP `tools/call` | Executes a tool call, routes through BashAgent for LLM-backed tools or directly for utility tools. Returns structured result. | +| MCP `prompts/list` | Exposes built-in prompt templates (e.g. "review-script", "generate-bats-test", "explain-command") as MCP prompts. | +| `--mcp` CLI flag | Start as an MCP stdio server: `gaia-bash --mcp`. Reads JSON-RPC from stdin, writes to stdout. Compatible with Claude Code MCP config. | +| Integration tests | Test API endpoints with curl/httplib. Test MCP protocol with a mock client. | + +**Architecture:** + +``` +External tool (Claude Code, OpenCode, curl) + │ + ├── HTTP REST API (:8200) + │ └── /v1/chat/completions + │ └── /v1/tools/{name} + │ └── /health + │ + └── MCP stdio transport + └── tools/list, tools/call + └── prompts/list + │ + ▼ + BashAgent : Agent + (same agent instance, same tools) +``` + +**Usage examples:** + +```bash +# Start as API server +gaia-bash --serve --port 8200 + +# Query via curl +curl http://localhost:8200/v1/chat/completions \ + -H "Content-Type: application/json" \ + -d '{"messages":[{"role":"user","content":"write a backup script"}]}' + +# Use as MCP server in Claude Code (~/.claude/settings.json) +{ + "mcpServers": { + "gaia-bash": { + "command": "gaia-bash", + "args": ["--mcp"] + } + } +} + +# Direct tool call via API +curl http://localhost:8200/v1/tools/bash_execute \ + -H "Content-Type: application/json" \ + -d '{"command":"ls -la","timeoutMs":5000}' +``` + +**Estimated effort:** 3–4 weeks + +#### M2-P6: Eval Integration + +**Scope:** Extend the GAIA evaluation framework to validate the bash agent against bash-specific scenarios. + +**Deliverables:** + +| Component | Description | +|---|---| +| Bash eval scenarios | 20+ test scenarios covering: script writing, script review, file operations, ShellCheck compliance, BATS test generation, error debugging, POSIX portability. | +| Eval adapter | Connect `gaia eval agent` to the bash agent's REST API (`--serve` mode).

Subcommand (`gaia bash`) is more discoverable. Current plan (M2-P4) does both — Python bridge subcommand delegates to the native binary if found on PATH. + +2. **Model auto-download.** Should `gaia-bash` auto-download Qwen3-Coder-Next on first run (like `gaia init`), or require explicit setup? Auto-download is better UX but needs the Lemonade model download API from C++. Deferred to M2-P4. + +3. **MCP tool passthrough.** Should `gaia-bash` support connecting to MCP servers for extensibility? This would allow users to add custom tools (e.g. a Docker MCP server, a Kubernetes MCP server) without recompiling. Low effort since `MCPClient` already exists in `gaia_core` — question is whether to enable it in M2-P1 or defer. + +4. **M1 validation strategy.** The plan proposes refactoring `wifi_agent` to use M1 primitives as a validation gate before starting M2. Is that sufficient, or should we build a minimal "demo agent" (no domain tools, just REPL + TUI + file I/O) as the M1 acceptance test? + +5. **Lemonade Server function calling support.** Native function calling (M1-P4) depends on Lemonade Server accepting the OpenAI `"tools"` parameter. Current Lemonade docs don't confirm this explicitly. Needs verification before M1-P4 work begins — if unsupported, M1-P4 becomes a Lemonade Server feature request rather than a `gaia_core` task. + +--- + +## References + +- [Best LLMs for Coding 2026 — WhatLLM](https://whatllm.org/best-llm-for-coding) +- [Qwen3-Coder-Next Complete Guide — DEV Community](https://dev.to/sienna/qwen3-coder-next-the-complete-2026-guide-to-running-powerful-ai-coding-agents-locally-1k95) +- [Qwen3-Coder-Next — HuggingFace](https://huggingface.co/Qwen/Qwen3-Coder-Next) +- [Qwen3-Coder-Next Real-World Tests — XDA](https://www.xda-developers.com/tested-qwen3-coder-next-four-local-ai-coding-models-gap-embarassing/) +- [Qwen3-Coder-Next Ultra-Sparse MoE — VentureBeat](https://venturebeat.com/technology/qwen3-coder-next-offers-vibe-coders-a-powerful-open-source-ultra-sparse-model-with-10x-higher-throughput-for-repo-tasks) +- [FTXUI — GitHub](https://github.com/ArthurSonzogni/FTXUI) +- [MarkdownFTXUI — GitHub](https://github.com/zvasilev/MarkdownFTXUI) +- [llama.cpp Function Calling — GitHub](https://github.com/ggml-org/llama.cpp/blob/master/docs/function-calling.md) +- [OpenCode TUI — opencode.ai](https://opencode.ai/docs/tui/) +- [Claude Code Overview — Anthropic](https://code.claude.com/docs/en/overview) +- [Local Autonomous Agent Stack — SitePoint](https://www.sitepoint.com/the-complete-stack-for-local-autonomous-agents--from-ggml-to-orchestration/) +- [Best Local LLMs for Coding — Overchat](https://overchat.ai/ai-hub/best-local-llm-for-coding) +- [Best Local LLMs 2026 — ToolHalla](https://toolhalla.ai/blog/best-local-llms-for-coding-2026) From ca712fec782ac7e9719f7fc3c71d25ff9067c7bb Mon Sep 17 00:00:00 2001 From: Ovtcharov Date: Thu, 7 May 2026 15:56:16 -0700 Subject: [PATCH 03/21] fix(cpp): ProcessRunner NOMINMAX + threaded pipe reading + FTXUI test linking MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Three build fixes found during first real MSVC compilation: 1. NOMINMAX: Windows min/max macros collide with std::min — define NOMINMAX before windows.h include in process.cpp. 2. Threaded pipe reading: the original sequential approach (read pipes then wait for process, or wait then read) either deadlocked on timeout tests or lost output on large-output tests. Fix: read stdout/stderr in std::thread workers concurrently with WaitForSingleObject. 3. FTXUI linking for tests: test_tui_console.cpp includes FTXUI headers but tests_mock only linked gaia_core (which has FTXUI as PRIVATE). Added explicit ftxui::component/dom/screen link to tests_mock when GAIA_BUILD_TUI is ON. Result: 431/435 tests pass on Windows MSVC 2022.

charset=UTF-8 Content-Transfer-Encoding: 8bit The `--json-events` answer event was missing token usage data, so the TUI/WebUI had no visibility into how many tokens each query consumed. Now the answer event includes a `usage` object with `prompt_tokens`, `completion_tokens`, and `total_tokens` — accumulated across all LLM calls in a multi-step query — so the frontend can render token consumption directly from the event stream. ## Test plan - [ ] `tests_mock --gtest_filter="JsonEventHandlerTest.*"` — all 23 tests pass (2 new: `FinalAnswerWithUsage`, `FinalAnswerZeroUsageOmitted`) - [ ] `gaia-bash.exe --json-events --query "what is 2+2?"` — verify `answer` event includes `usage` when Lemonade returns it - [ ] `gaia-bash.exe --json-events --query "hello"` — verify `usage` key is omitted when server returns zero tokens (graceful degradation) Closes #1205 Co-authored-by: Ovtcharov --- cpp/examples/process_agent.cpp | 3 +- cpp/include/gaia/agent.h | 11 ++++-- cpp/include/gaia/clean_console.h | 3 +- cpp/include/gaia/console.h | 9 +++-- cpp/include/gaia/json_event_handler.h | 3 +- cpp/include/gaia/tui_console.h | 3 +- cpp/include/gaia/types.h | 20 ++++++++++ cpp/src/agent.cpp | 54 +++++++++++++++++++++------ cpp/src/clean_console.cpp | 3 +- cpp/src/console.cpp | 6 ++- cpp/src/json_event_handler.cpp | 15 +++++--- cpp/src/tui_console.cpp | 3 +- cpp/tests/test_json_event_handler.cpp | 38 +++++++++++++++++++ 13 files changed, 140 insertions(+), 31 deletions(-) diff --git a/cpp/examples/process_agent.cpp b/cpp/examples/process_agent.cpp index 39e66b78a..9bc1659c0 100644 --- a/cpp/examples/process_agent.cpp +++ b/cpp/examples/process_agent.cpp @@ -701,7 +701,8 @@ static void cleanupBalloonNotify() { // --------------------------------------------------------------------------- class ProcessConsole : public gaia::CleanConsole { public: - void printFinalAnswer(const std::string& answer) override { + void printFinalAnswer(const std::string& answer, + const gaia::UsageStats& /*usage*/ = {}) override { if (answer.empty()) return;

On Windows, that means one restricted sibling directory can break Export All for otherwise valid agents. This catches `OSError` around the directory check, logs a debug skip reason, and treats unreadable entries as non-exportable. The regression test covers a valid custom agent next to an entry whose `agent.py` probe raises `PermissionError`. Tested: - `PYTHONPATH=src python -m pytest tests/unit/test_export_import.py -q` - `python -m ruff check src/gaia/installer/export_import.py tests/unit/test_export_import.py` - `python -m compileall -q src/gaia/installer/export_import.py tests/unit/test_export_import.py` - `git diff --check` --- src/gaia/installer/export_import.py | 6 +++++- tests/unit/test_export_import.py | 18 ++++++++++++++++++ 2 files changed, 23 insertions(+), 1 deletion(-) diff --git a/src/gaia/installer/export_import.py b/src/gaia/installer/export_import.py index 5d006d345..7aec1fe91 100644 --- a/src/gaia/installer/export_import.py +++ b/src/gaia/installer/export_import.py @@ -98,7 +98,11 @@ def _is_custom_agent_dir(path: Path) -> bool: were removed in v0.17.5; such directories are intentionally excluded from export so we don't ship bundles that the importer would reject.
