refactor(box): remove legacy in-process runtime code and clean up smells MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit After the architecture settled on always using an independent Box Runtime service, several pieces of compatibility code and design shortcuts were left behind. This commit cleans them up: - Remove `LocalBoxRuntimeClient` and `create_box_runtime_client` from production code (moved to test-only helper). - Remove unused `_clip_bytes` method from backend. - Remove `__langbot_session_placeholder__` hack by making `BoxSpec.cmd` default to empty and validating non-empty only in `runtime.execute()`. - Extract `get_box_config()` helper to eliminate 5× duplicated config access boilerplate. - Remove `session_id`/`host_path`/`host_path_mode` from the LLM-facing tool schema to enforce request-scoped session isolation. - Fix dual shutdown path: `NativeToolLoader.shutdown()` no longer calls `box_service.shutdown()` (handled by `Application.dispose()`). - Simplify `_assert_session_compatible` with a loop. - Inline client creation in `BoxRuntimeConnector`. - Remove redundant `BOX__RUNTIME_URL` env var from docker-compose (auto-detected by code).

When no container runtime exists, LangBot starts normally and stdio MCP falls back to host-direct execution. ## What changed ### MCP stdio → Box integration (mcp.py) - Add `MCPServerBoxConfig` pydantic model for structured box configuration with validation and defaults (network, host_path_mode, timeouts, resources) - Auto-infer `host_path` from command/args with venv detection: recognizes `.venv/bin/python` patterns and walks up to the project root - Rewrite host paths to container `/workspace` paths transparently - Replace venv python commands with container-native `python` - Auto-detect `pyproject.toml`/`setup.py`/`requirements.txt` and run `pip install` inside the container before starting the MCP server - Copy project to `/tmp` before install to handle read-only mounts - Add retry with exponential backoff (3 retries, 2s/4s/8s delays) - Add Box managed process health monitoring (poll every 5s) - Fix session leak: `_cleanup_box_stdio_session()` now runs in `finally` block of `_lifecycle_loop`, covering all exit paths - Fix retry logic: `_ready_event` is only set after all retries exhaust or on success, not on first failure - Enhance `get_runtime_info_dict()` with `box_session_id` and `box_enabled` ### Box security (security.py — new) - `validate_sandbox_security()` blocks dangerous host paths: `/etc`, `/proc`, `/sys`, `/dev`, `/root`, `/boot`, `/run`, docker.sock, podman socket - Called at the start of `CLISandboxBackend.start_session()` ### Box models (models.py) - Add `BoxHostMountMode.NONE` — skips volume mount entirely - Adjust `validate_host_mount_consistency` to allow arbitrary workdir when `host_path_mode=NONE` ### Box backend (backend.py) - Add `validate_sandbox_security()` call in `start_session()` - Add `langbot.box.config_hash` label on containers for drift detection - Handle `BoxHostMountMode.NONE` — skip `-v` mount arg - Add `cleanup_orphaned_containers()` to base class (no-op default) and CLI implementation (single batched `rm -f` command) ### Box runtime (runtime.py) - Call `cleanup_orphaned_containers()` during `initialize()` to remove lingering containers from previous runs ### Box service (service.py) - Graceful degradation: `initialize()` catches runtime errors and sets `available=False` instead of crashing LangBot startup - Add `available` property and guard on `execute_sandbox_tool()` - Add `skip_host_mount_validation` parameter to `build_spec()` and `create_session()` — MCP paths are admin-configured and trusted, bypassing `allowed_host_mount_roots` restrictions meant for LLM-generated sandbox_exec commands ### Default behavior - stdio MCP servers automatically use Box when `box_service.available` is True (Podman/Docker detected); no explicit `box` config needed - When no container runtime exists, falls back to host-direct stdio - MCP Box defaults: `network=on` (for pip install), `read_only_rootfs=false` (for site-packages), `host_path_mode=ro`, `startup_timeout=120s` ### Tests - `test_box_security.py`: blocked paths, safe paths, subpath rejection - `test_mcp_box_integration.py`: config model, path rewriting, venv unwrap, host_path inference, payload building, runtime info, box availability check - `test_box_service.py`: `BoxHostMountMode.NONE` validation tests --- src/langbot/pkg/box/backend.py | 82 +++- src/langbot/pkg/box/client.py | 57 ++- src/langbot/pkg/box/errors.py | 8 + src/langbot/pkg/box/models.py | 55 +++ src/langbot/pkg/box/runtime.py | 168 ++++++- src/langbot/pkg/box/security.py | 42 ++ src/langbot/pkg/box/server.py | 96 +++- src/langbot/pkg/box/service.py | 92 +++- src/langbot/pkg/provider/tools/loaders/mcp.py | 351 ++++++++++++++- .../box/test_box_managed_process.py | 103 +++++ tests/unit_tests/box/test_box_security.py | 59 +++ tests/unit_tests/box/test_box_service.py | 50 +++ .../provider/test_mcp_box_integration.py | 421 ++++++++++++++++++ 13 files changed, 1543 insertions(+), 41 deletions(-) create mode 100644 src/langbot/pkg/box/security.py create mode 100644 tests/unit_tests/box/test_box_managed_process.py create mode 100644 tests/unit_tests/box/test_box_security.py create mode 100644 tests/unit_tests/provider/test_mcp_box_integration.py diff --git a/src/langbot/pkg/box/backend.py b/src/langbot/pkg/box/backend.py index ea74a0900..fda0846f0 100644 --- a/src/langbot/pkg/box/backend.py +++ b/src/langbot/pkg/box/backend.py @@ -4,6 +4,8 @@ import asyncio import dataclasses import datetime as dt +import hashlib +import json import logging import re import shlex @@ -12,7 +14,8 @@ import uuid from .errors import BoxError -from .models import DEFAULT_BOX_MOUNT_PATH, BoxExecutionResult, BoxExecutionStatus, BoxSessionInfo, BoxSpec +from .models import DEFAULT_BOX_MOUNT_PATH, BoxExecutionResult, BoxExecutionStatus, BoxHostMountMode, BoxSessionInfo, BoxSpec +from .security import validate_sandbox_security # Hard cap on raw subprocess output to prevent unbounded memory usage. # Container timeout already bounds duration, but fast commands can still @@ -54,6 +57,13 @@ async def exec(self, session: BoxSessionInfo, spec: BoxSpec) -> BoxExecutionResu async def stop_session(self, session: BoxSessionInfo): pass + async def start_managed_process(self, session: BoxSessionInfo, spec): + raise BoxError(f'{self.name} backend does not support managed processes') + + async def cleanup_orphaned_containers(self): + """Remove lingering containers from previous runs.

17 00:00:00 2001 From: youhuanghe <1051233107@qq.com> Date: Sat, 21 Mar 2026 05:19:48 +0000 Subject: [PATCH 013/129] feat(box/mcp): instance-based orphan cleanup, error classification, session API, and integration tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Changes ### Precise orphan container cleanup - Runtime generates a unique instance_id on startup - Every container gets a `langbot.box.instance_id` label - `cleanup_orphaned_containers()` only removes containers from previous instances, preserving containers owned by the current one - Containers from older versions (no label) are also cleaned up - `cleanup_orphaned_containers` added to `BaseSandboxBackend` as a no-op default method, removing hasattr duck-typing ### Fine-grained MCP error classification - New `MCPSessionErrorPhase` enum with 7 phases: session_create, dep_install, process_start, relay_connect, mcp_init, runtime, tool_call - Each phase in `_init_box_stdio_server()` sets the error phase before re-raising, enabling precise failure diagnosis - `retry_count` tracked across retry attempts - `get_runtime_info_dict()` exposes `error_phase` and `retry_count` ### GET /v1/sessions/{id} API - `BoxRuntime.get_session()` returns session details including managed process info when present - `handle_get_session` HTTP handler + route in server.py - `BoxRuntimeClient.get_session()` abstract method + remote impl ### stdio defaults to Box when runtime is available - `_uses_box_stdio()` checks `box_service.available` instead of requiring explicit `box` key in server_config - `BoxService.initialize()` catches runtime errors gracefully, sets `available=False` instead of crashing LangBot startup - When no container runtime exists, stdio MCP falls back to host-direct execution ### Code quality (from /simplify review) - Extracted `_VENV_DIRS` / `_VENV_BIN_DIRS` module-level constants - Removed dead `_box_network_mode()` method and unused `bc` variable - Fixed broken import `from ....box.models` → `from ...box.models` - Cached `_resolve_host_path()` result — computed once, passed through - Config hash now includes `host_path` field - Batched orphan cleanup into single `rm -f` command ### Session leak fix - `_cleanup_box_stdio_session()` now runs in `_lifecycle_loop`'s finally block, covering all exit paths (normal shutdown, error, retry, final failure) ### Integration tests - 6 end-to-end tests covering managed process lifecycle, WebSocket stdio bidirectional IO, session cleanup verification, single session query, process exit detection, and orphan cleanup safety --- src/langbot/pkg/box/backend.py | 34 +- src/langbot/pkg/box/client.py | 12 + src/langbot/pkg/box/runtime.py | 16 +- src/langbot/pkg/box/server.py | 10 +

16:09:06 +0800 Subject: [PATCH 029/129] feat(skills): add Agent Skills management system (#1917) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * feat(skills): add Agent Skills management system Implement comprehensive skills management feature inspired by agentskills spec: Backend: - Add Skill and SkillPipelineBinding database entities - Add database migration (dbm018) for skills tables - Implement SkillManager for skill loading, matching, and resolution - Implement SkillService for CRUD operations - Add skills API endpoints for skill and pipeline binding management - Integrate skill index injection into pipeline preprocessor - Add skill activation detection in LocalAgentRunner Frontend: - Add Skills page with listing, search, and type filter - Add SkillDetailDialog for create/edit with preview - Add SkillCard and SkillForm components - Add skills API methods to BackendClient - Add skills entry to sidebar navigation - Add i18n translations (en-US, zh-Hans) Features: - Support skill and workflow types - Sub-skill composition via {{INVOKE_SKILL: name}} syntax - Progressive disclosure (index in prompt, full instructions on activation) - Pipeline-specific skill bindings with priority * fix: resolve cherry-pick conflicts for agentskills onto sandbox - Remove non-existent external_kb service import - Add skill_mgr mock to localagent sandbox_exec tests - Keep database version at 24 (sandbox branch's latest) * feat(skills): upgrade to package-backed skills with sandbox execution Evolve the skills system from pure prompt-based to package-backed with sandbox tool execution support: - Add source_type/package_root/entry_file/skill_tools fields to Skill entity - SkillManager loads SKILL.md from local package directories - SkillToolLoader as 4th dispatch layer in ToolManager (query-scoped) - LocalAgent injects skill tools into use_funcs on skill activation - BoxService.execute_skill_tool() runs scripts in sandbox (ro mount, env params) - Skill tool names auto-namespaced as skill__{skill}__{tool} - API validation for package_root allowlist and entry path traversal - Frontend source_type toggle, package_root input, skill_tools editor - Migration renumbered to 025 with ALTER TABLE fallback for existing DBs - Fix unclosed limitation section in i18n files - Fix skills API methods misplaced outside BackendClient class * fix: test info * feat(skills): switch skills to package-backed storage and add import tooling - skills 从 inline/package 双轨收敛成 package-first - instructions 改为写入并读取 SKILL.md - 新增本地目录扫描和 GitHub 安装 skill - 前端把 skills 整合进 plugins 页，新增 SkillsComponent 和 GitHub 导入弹窗 - skill form 去掉 source_type / type 筛选，改成目录扫描驱动 - Box skill tool 挂载模式从 ro 改成 rw - 测试和中英文文案同步更新 * feat: simplify langbot skill create and import * refactor(skills): clean up legacy skill API and harden activation flow * refactor(skills): remove skill dependency expansion and add skill_get * fix: lint * fix: delete * fix(skills): align tool manager loader initialization * refactor: remove sandbox execute skill * fix(skills): hide activation markers and isolate skill activation flow * refactor(skills): switch skill model to filesystem-backed packages * refactor(skills): switch skill model to filesystem-backed packages * refactor(skills): unify runtime skill access around filesystem paths * refactor(skills): unify runtime skill access around filesystem paths * feat(skills): align rw package design and fix skill activation, visibility, and lint issues * refactor(skills): replace rich authoring API with import/reload flow and update Box design doc * feat(box): add sandbox_exec tool loop for local-agent calculations * feat(box): add host workspace mounting and sandbox_exec guidance * feat(box): add BoxProfile with resource limits and improved output truncation - Implement head+tail output truncation (60/40 split) so LLM sees both beginning and final results; add streaming byte-limited reads in backend to prevent unbounded memory usage (_MAX_RAW_OUTPUT_BYTES = 1MB) - Define BoxProfile model with locked fields and max_timeout_sec clamping - Add four built-in profiles: default, offline_readonly, network_basic, network_extended with differentiated resource and security constraints - Add resource limit fields to BoxSpec (cpus, memory_mb, pids_limit, read_only_rootfs) and pass corresponding container CLI flags (--cpus, --memory, --pids-limit, --read-only, --tmpfs) - Profile loaded from config (box.profile), applied in service layer before BoxSpec validation; locked fields cannot be overridden by tool-call parameters * feat(box): add obs * refactor(box): unify box service lifecycle and local runtime management * refactor(box): remove legacy in-process runtime code and clean up smells After the architecture settled on always using an independent Box Runtime service, several pieces of compatibility code and design shortcuts were left behind. This commit cleans them up: - Remove `LocalBoxRuntimeClient` and `create_box_runtime_client` from production code (moved to test-only helper). - Remove unused `_clip_bytes` method from backend. - Remove `__langbot_session_placeholder__` hack by making `BoxSpec.cmd` default to empty and validating non-empty only in `runtime.execute()`. - Extract `get_box_config()` helper to eliminate 5× duplicated config access boilerplate. - Remove `session_id`/`host_path`/`host_path_mode` from the LLM-facing tool schema to enforce request-scoped session isolation. - Fix dual shutdown path: `NativeToolLoader.shutdown()` no longer calls `box_service.shutdown()` (handled by `Application.dispose()`). - Simplify `_assert_session_compatible` with a loop. - Inline client creation in `BoxRuntimeConnector`. - Remove redundant `BOX__RUNTIME_URL` env var from docker-compose (auto-detected by code). Co-Authored-By: Claude Opus 4.6 (1M context) * feat(box/mcp): integrate MCP stdio with Box sandbox — auto-isolation, dep install, security ## Summary When Podman/Docker is available, all stdio-mode MCP servers now automatically run inside Box containers with dependency installation, path rewriting, and lifecycle management. When no container runtime exists, LangBot starts normally and stdio MCP falls back to host-direct execution. ## What changed ### MCP stdio → Box integration (mcp.py) - Add `MCPServerBoxConfig` pydantic model for structured box configuration with validation and defaults (network, host_path_mode, timeouts, resources) - Auto-infer `host_path` from command/args with venv detection: recognizes `.venv/bin/python` patterns and walks up to the project root - Rewrite host paths to container `/workspace` paths transparently - Replace venv python commands with container-native `python` - Auto-detect `pyproject.toml`/`setup.py`/`requirements.txt` and run `pip install` inside the container before starting the MCP server - Copy project to `/tmp` before install to handle read-only mounts - Add retry with exponential backoff (3 retries, 2s/4s/8s delays) - Add Box managed process health monitoring (poll every 5s) - Fix session leak: `_cleanup_box_stdio_session()` now runs in `finally` block of `_lifecycle_loop`, covering all exit paths - Fix retry logic: `_ready_event` is only set after all retries exhaust or on success, not on first failure - Enhance `get_runtime_info_dict()` with `box_session_id` and `box_enabled` ### Box security (security.py — new) - `validate_sandbox_security()` blocks dangerous host paths: `/etc`, `/proc`, `/sys`, `/dev`, `/root`, `/boot`, `/run`, docker.sock, podman socket - Called at the start of `CLISandboxBackend.start_session()` ### Box models (models.py) - Add `BoxHostMountMode.NONE` — skips volume mount entirely - Adjust `validate_host_mount_consistency` to allow arbitrary workdir when `host_path_mode=NONE` ### Box backend (backend.py) - Add `validate_sandbox_security()` call in `start_session()` - Add `langbot.box.config_hash` label on containers for drift detection - Handle `BoxHostMountMode.NONE` — skip `-v` mount arg - Add `cleanup_orphaned_containers()` to base class (no-op default) and CLI implementation (single batched `rm -f` command) ### Box runtime (runtime.py) - Call `cleanup_orphaned_containers()` during `initialize()` to remove lingering containers from previous runs ### Box service (service.py) - Graceful degradation: `initialize()` catches runtime errors and sets `available=False` instead of crashing LangBot startup - Add `available` property and guard on `execute_sandbox_tool()` - Add `skip_host_mount_validation` parameter to `build_spec()` and `create_session()` — MCP paths are admin-configured and trusted, bypassing `allowed_host_mount_roots` restrictions meant for LLM-generated sandbox_exec commands ### Default behavior - stdio MCP servers automatically use Box when `box_service.available` is True (Podman/Docker detected); no explicit `box` config needed - When no container runtime exists, falls back to host-direct stdio - MCP Box defaults: `network=on` (for pip install), `read_only_rootfs=false` (for site-packages), `host_path_mode=ro`, `startup_timeout=120s` ### Tests - `test_box_security.py`: blocked paths, safe paths, subpath rejection - `test_mcp_box_integration.py`: config model, path rewriting, venv unwrap, host_path inference, payload building, runtime info, box availability check - `test_box_service.py`: `BoxHostMountMode.NONE` validation tests * feat(box/mcp): instance-based orphan cleanup, error classification, session API, and integration tests ## Changes ### Precise orphan container cleanup - Runtime generates a unique instance_id on startup - Every container gets a `langbot.box.instance_id` label - `cleanup_orphaned_containers()` only removes containers from previous instances, preserving containers owned by the current one - Containers from older versions (no label) are also cleaned up - `cleanup_orphaned_containers` added to `BaseSandboxBackend` as a no-op default method, removing hasattr duck-typing ### Fine-grained MCP error classification - New `MCPSessionErrorPhase` enum with 7 phases: session_create, dep_install, process_start, relay_connect, mcp_init, runtime, tool_call - Each phase in `_init_box_stdio_server()` sets the error phase before re-raising, enabling precise failure diagnosis - `retry_count` tracked across retry attempts - `get_runtime_info_dict()` exposes `error_phase` and `retry_count` ### GET /v1/sessions/{id} API - `BoxRuntime.get_session()` returns session details including managed process info when present - `handle_get_session` HTTP handler + route in server.py - `BoxRuntimeClient.get_session()` abstract method + remote impl ### stdio defaults to Box when runtime is available - `_uses_box_stdio()` checks `box_service.available` instead of requiring explicit `box` key in server_config - `BoxService.initialize()` catches runtime errors gracefully, sets `available=False` instead of crashing LangBot startup - When no container runtime exists, stdio MCP falls back to host-direct execution ### Code quality (from /simplify review) - Extracted `_VENV_DIRS` / `_VENV_BIN_DIRS` module-level constants - Removed dead `_box_network_mode()` method and unused `bc` variable - Fixed broken import `from ....box.models` → `from ...box.models` - Cached `_resolve_host_path()` result — computed once, passed through - Config hash now includes `host_path` field - Batched orphan cleanup into single `rm -f` command ### Session leak fix - `_cleanup_box_stdio_session()` now runs in `_lifecycle_loop`'s finally block, covering all exit paths (normal shutdown, error, retry, final failure) ### Integration tests - 6 end-to-end tests covering managed process lifecycle, WebSocket stdio bidirectional IO, session cleanup verification, single session query, process exit detection, and orphan cleanup safety * refactor: use rpc * fix: import * refactor(box): clean up sandbox subsystem code quality and efficiency - Fix O(n²) stderr trimming in runtime.py with running length tracker - Remove dead code: RESERVED_CONTAINER_PATHS, _subprocess_wait_task, unused config_hash computation, unused imports - Deduplicate connection callback in BoxRuntimeConnector, parse URL once - Use enum comparison instead of stringly-typed spec.network.value check - Replace manual _result_to_dict/_session_to_dict with model_dump() - Cache NativeToolLoader tool definition and sandbox system guidance - Extract _is_path_under() helper to eliminate duplicated path checks - Import SANDBOX_EXEC_TOOL_NAME from native.py instead of redefining - Add JSON startswith guard in logging_utils to skip futile json.loads - Fix ruff lint errors (F401 unused imports, F841 unused variables) * fix: ruff * refactor(sandbox): keep box logic out of pipeline and localagent - Move sandbox system-prompt guidance from LocalAgentRunner into BoxService.get_system_guidance() so all box domain knowledge stays in the box module. - Remove standalone logging_utils.py; merge format_result_log() into MessageHandler base class alongside cut_str(). - Strip sandbox-specific JSON parsing from log formatting; tool results now use generic truncation. - Revert TYPE_CHECKING changes in stage.py and runner.py that were unrelated to this feature. - Skip two test files affected by a pre-existing circular import (runner ↔ app) until the import cycle is resolved in a separate PR. * refactor(box): move box runtime to langbot-plugin-sdk Extract self-contained box runtime modules (actions, backend, client, errors, models, runtime, security, server) to langbot-plugin-sdk and update all imports to use `langbot_plugin.box.*`. Keep only service and connector in LangBot core as they depend on the Application context. - Update docker-compose to use `langbot_plugin.box.server` entry point - Update pyproject.toml to use local SDK via `tool.uv.sources` - Remove migrated source files and their unit/integration tests - Update remaining test imports to match new module paths * fix: ruff * fix(box): tighten sandbox exposure and restore box integration coverage * refactor(types): remove quoted annotations under postponed evaluation * chore(sandbox): move MCP loader changes to follow-up branch * refactor(plugins): simplify GitHub install flow to default master archive * revert(api): restore plugin GitHub import flow in plugins controller * Improve data-root handling and skill install previews * Add managed skill authoring tools for local agents * Refactor the skills UI around sidebar detail pages * Document why managed skill authoring tools bypass box * fix: lint * feat(web): refactor plugin/skill install flows and fix skills page - Fix sidebar skill icon - Add skills route and error page component - Refactor plugin GitHub install from dialog modal to inline card - Add skill install dropdown menu (create/upload/github) in sidebar - Wire sidebar → skills page communication via pendingSkillInstallAction context - Add i18n keys for error page and skill install actions * fix(web): persist sidebar collapsible section open state on navigation Sections opened via sub-item navigation now retain their expanded state when the user switches to a different section, instead of collapsing because the isActive fallback becomes false. --------- Co-authored-by: youhuanghe <1051233107@qq.com> Co-authored-by: Claude Opus 4.6 (1M context) Co-authored-by: Junyan Qin --- pyproject.toml | 4 +- src/langbot/__main__.py | 4 +- .../controller/groups/pipelines/pipelines.py | 16 +- .../pkg/api/http/controller/groups/plugins.py | 81 +- .../pkg/api/http/controller/groups/skills.py | 146 ++++ src/langbot/pkg/api/http/service/pipeline.py | 5 + src/langbot/pkg/api/http/service/skill.py | 743 ++++++++++++++++++ src/langbot/pkg/box/service.py | 5 + src/langbot/pkg/core/app.py | 7 +- src/langbot/pkg/core/stages/build_app.py | 10 + src/langbot/pkg/pipeline/preproc/preproc.py | 69 +- .../pkg/provider/runners/localagent.py | 152 +++- .../pkg/provider/tools/loaders/native.py | 164 +++- .../pkg/provider/tools/loaders/skill.py | 285 +++++++ .../provider/tools/loaders/skill_authoring.py | 391 +++++++++ src/langbot/pkg/provider/tools/toolmgr.py | 61 +- src/langbot/pkg/skill/__init__.py | 3 + src/langbot/pkg/skill/activation.py | 154 ++++ src/langbot/pkg/skill/manager.py | 287 +++++++ src/langbot/pkg/skill/utils.py | 37 + src/langbot/pkg/utils/paths.py | 74 +- src/langbot/templates/config.yaml | 1 + .../provider/test_localagent_sandbox_exec.py | 212 +++++ tests/unit_tests/provider/test_skill_tools.py | 569 ++++++++++++++ .../provider/test_tool_manager_native.py | 17 +- tests/unit_tests/test_paths.py | 23 + tests/unit_tests/test_preproc.py | 134 ++++ tests/unit_tests/test_skill_service.py | 408 ++++++++++ .../components/home-sidebar/HomeSidebar.tsx | 130 ++- .../home-sidebar/SidebarDataContext.tsx | 31 + .../home-sidebar/sidbarConfigList.tsx | 23 +- web/src/app/home/layout.tsx | 7 +- .../pipeline-extensions/PipelineExtension.tsx | 234 +++++- web/src/app/home/plugins/page.tsx | 487 ++++++------ .../app/home/skills/SkillDetailContent.tsx | 166 ++++ .../components/SkillGithubImportPanel.tsx | 645 +++++++++++++++ .../components/skill-form/SkillForm.tsx | 249 ++++++ web/src/app/home/skills/page.tsx | 135 ++++ .../CreateCardComponent.tsx | 27 -
