Canonical page: https://toolindex.org/tools/acswi/ Type: CLI Category: Operations Version: 0.2.0 License: MIT Source: https://github.com/OpenRootdev/acswi Distribution: https://github.com/OpenRootdev/acswi/releases/download/v0.2.0/acswi-windows-x64.zip Scope: acswi.exe (the command) and acswi-desktop.exe (the window and tray menu) plus the licence. No source, docs or preview media. ## Installation ### 1. Download and unzip Unzip both programs into a folder on your PATH. Windows SmartScreen may warn the first time, because the programs are not code-signed yet. Release v0.2.0: https://github.com/OpenRootdev/acswi/releases/tag/v0.2.0 ### 2. Add a second account acswi saves the account you are signed in to now, signs the app out and lets you sign in the other one. After that, acswi on its own lists every app with numbered accounts; type a number to switch. ``` acswi add codex acswi ``` ### 3. Switch by name, or from scripts and agents acswi switches directly. Add --json for machine-readable output with stable exit codes; acswi never prints a token or password. Usage guide: https://github.com/OpenRootdev/acswi/blob/main/docs/usage.md ``` acswi claude work acswi gh sam-dev --json ``` ## Manual setup - Windows 11 (Windows 10 with the WebView2 runtime should work but is not tested). - Each app you want to switch, signed in once per account through acswi. - Apps not built in need a short TOML definition; acswi learn watches the app while you sign in and drafts one. ## Additional notes - Built in: GitHub CLI, Azure CLI, Claude Code, Codex CLI, Cursor, GitHub Desktop and Discord. - Saved sign-ins stay on the PC, encrypted with Windows DPAPI for the current user. Anything running as that user can still decrypt them, the same protection the apps give their own tokens. - Apps that keep several accounts themselves (GitHub CLI, Azure CLI) are switched with their own commands; nothing is copied for them. ## Contents - tools: acswi CLI, acswi-desktop window and tray, Windows 11 ## Review scope artifact-checked; reviewed 2026-11-03. Windows 11: the 17 automated tests pass (real DPAPI and Credential Manager). GitHub CLI and Azure CLI were switched between real accounts from the CLI and from the window; Discord and Cursor were switched both ways on real accounts. v0.2.0 release ZIP contents and the README download link checked. Claude Code, Codex CLI, GitHub Desktop and the tray menu are covered by automated tests only.

Start with a repository you control Start a new client session and request a review of changes split into small commits. Choose the branch and manual or automatic approval mode at session setup. Review each proposed change and configure the project's meaningful checks. ## Manual setup - An agent client that supports skills, Git, an existing working tree you are authorized to modify, and the project's own test and lint tools. - No separate MCP service or API key is required by this skill. Your agent client has its own account and model requirements. ## Additional notes - By Shahwat Hasnaine. The source repository contains additional independently scoped skills. - Manual approval gates each commit. Automatic mode permits a commit only after a clean review, passing checks and isolation verification; findings require human approval. - The workflow excludes pushing, amending, rebasing and hard resets. Its instructions do not guarantee correct code or replace project-specific checks. - Reviewed from source documentation only. The workflow was not executed and no third-party repository was modified. ## Contents - skills: 1 - files: 1 - mcp_tools: 0 - tools: Git, A skills-compatible coding agent, Project-specific test and lint tools ## Review scope setup-reviewed; reviewed 2026-11-05. Maintainer approved inclusion, and the ToolIndex operator requested publication. The pinned README, focused SKILL.md, complete file tree and MIT license were inspected. Installation scope and manual/automatic approval behavior documented. The skill was not installed or executed; no runtime or correctness guarantee.

Canonical page: https://toolindex.org/tools/harneloop/ Type: CLI Category: Coding Version: 0.0.2 License: Apache-2.0 Source: https://github.com/OpenRootdev/Harneloop Distribution: https://pypi.org/project/harneloop/0.0.2/ Scope: The harneloop command-line tool as a Python package. The repository also holds docs, examples, tests and translations that are not needed to use it. ## Installation ### 1. Install the command Install it as an isolated tool with uv, then run the doctor check. You can also use python -m pip install harneloop in your own Python 3.11+ environment. Harneloop on PyPI: https://pypi.org/project/harneloop/ ``` uv tool install harneloop harneloop doctor ``` ### 2. Give your agent the repository Harneloop is meant to be driven by an agent with file and terminal access. Ask it to read the README and docs/agent-onboarding.md, then use Harneloop to create a harness unit for the task you want it to get better at. Agent quick start prompt: https://github.com/OpenRootdev/Harneloop#agent-quick-start ``` harneloop onboard --format json ``` ### 3. Or start it yourself harneloop setup opens a guided menu that creates and registers a harness unit. After that you can check any unit by name from any folder. ``` harneloop setup harneloop units list ``` ## Manual setup - Python 3.11 or newer and git. uv is recommended for an isolated install; if uv says its tool folder is not on PATH, run uv tool update-shell and open a new terminal. - You bring the task and the environment it runs in. Harneloop does not discover endpoints, tools, screenshots or output paths for you; the agent maps them into the harness unit. ## Additional notes - Public alpha. The core loop works; the first published case study is Blender scene construction with ViperMesh. - It changes the harness around the model (instructions, tools, context and checks), not the model itself. A proposed change becomes the working version only after a test supports it. ## Contents - skills: 1 - tools: harneloop CLI, Python 3.11+, git ## Review scope setup-reviewed; reviewed 2026-11-01. Windows: installed harneloop 0.0.2 from PyPI in an isolated uv environment and harneloop doctor passed (Python, PyYAML, git, writable folder). README install and agent quick start reviewed. A full harness-unit run was not repeated for this listing.

No videos or dependencies. ## Installation ### 1. Download the focused package Download the ZIP and SHA256SUMS.txt from the release. Verify the checksum with your system's checksum tool, then extract into a folder you control. Release and checksums: https://github.com/Ker102/smooth-motion-graphics/releases/tag/v1.0.0 ### 2. Point your agent at the skill Ask any agent to read this file. For an Agent Skills-compatible client, copy the complete skill folder to its documented skills directory. Discovery differs by client. ``` skills/smooth-motion-graphics/SKILL.md ``` ### 3. Optional: render a first preview Install Node.js 20+ and system FFmpeg for video encoding. From the skill folder, run these commands. Copy and adapt the example brief for your own brand before delivering a video. ``` npm ci node scripts/render.cjs stills assets/brand-brief.example.json output node scripts/render.cjs video assets/brand-brief.example.json output ``` ## Manual setup - No MCP, API key or image model is required. The instructions can be used with your existing animation tools. - Optional reference renderer: Node.js 20+, system FFmpeg with libx264 for encoding, and your own licensed font if desired. - Set SMOOTH_FFMPEG or SMOOTH_FONT_PATH only if using a non-default executable or local font. Inspect preview frames on the machine that will encode the video. ## Additional notes - Reference layouts: title, 2–4 inputs into a central object, and 3–7 workflow cards with explicit directed edges. Extend them when the story needs a different layout. - Optional Harneloop thin export is available in the release. It is a promoted snapshot for reuse; it does not include private development runs or claim a one-command import. - The example uses fictional Luma branding. Replace the story with verified facts for your product. ## Contents - skills: 1 - references: 1 - renderers: 1 - files: 6 - mcp_tools: 0 - tools: Node.js + @napi-rs/canvas (optional), FFmpeg (optional encoding) ## Review scope artifact-checked; reviewed 2026-10-10. Windows: fictional example and alternate brand frames inspected; layout/direction tests and 1080p60 encode/decode checked. Other platforms not runtime-tested. Evidence source: https://github.com/Ker102/smooth-motion-graphics#what-gets-checked ## Built with Harneloop Extracted, tested and promoted through an external Harneloop unit. The optional thin export contains the verified skill. https://harneloop.kaelux.dev # ViperMesh for Blender > A local Blender MCP workflow for building and checking 3D scenes. Canonical page: https://toolindex.org/tools/vipermesh-blender/ Type: MCP server Category: 3D & Blender Version: 1.3.0 License: MIT; preserve NOTICE.md attribution Source: https://github.com/OpenRootdev/vipermesh-blender Distribution: https://github.com/OpenRootdev/vipermesh-blender/releases/download/v1.3.0/vipermesh-blender-1.3.0.mcpb Scope: Focused MCPB server bundle. Install the separate Blender addon and optional source skill; the full mixed repository is not needed. ## Installation ### 1. Install and enable the Blender addon Download the addon from the release. In Blender, open Edit → Preferences → Add-ons → Install from Disk, select the downloaded Python addon file and enable ViperMesh for Blender. The maintainer currently tests Blender 5.2. Download Blender addon: https://github.com/OpenRootdev/vipermesh-blender/releases/download/v1.3.0/vipermesh-for-blender-addon-v1.3.0.py ### 2. Connect your MCP client Install Node.js 20+. Import the MCPB bundle into a client supporting local MCPB extensions. Keep the Blender viewport sidebar's ViperMesh Local Bridge running. Source-build/stdio configuration is documented in the repository for clients without MCPB import. Release, checksums and alternatives: https://github.com/OpenRootdev/vipermesh-blender/releases/tag/v1.3.0 ### 3. Load the agent skill and start a session Read the skill plus its five relative reference files from the linked source folder. Copy the whole folder to your agent's documented skill location if desired. Have the agent bootstrap, inspect the existing scene and discover relevant operations before editing. Skill and reference folder: https://github.com/OpenRootdev/vipermesh-blender/tree/main/skills/using-vipermesh-blender ``` bootstrap_vipermesh_session get_blender_agent_context list_blender_tools ``` ## Manual setup - A local Blender session, enabled addon, and running Local Bridge are required. This is a local workstation connector, not a hosted Blender service. - MCP client needs stdio support; MCPB import is optional. The client should manage one persistent Node server process per agent session. - The addon listens on loopback 127.0.0.1:9876. The connector can change scene state and exposes code execution; use it with trusted agents and approved output paths. ## Additional notes - Existing repository and release assets are listed unchanged. Nine top-level MCP tools route to a larger Blender operation registry; nine is not the total number of Blender operations. - The public connector and guidance are distinct from private studio capabilities and benchmark traces. Those are not included in this package. - Retain the source license and NOTICE.md when redistributing. Consult the upstream README for current supported Blender versions. ## Contents - skills: 1 - references: 5 - mcp_tools: 9 - tools: ViperMesh MCP server, Blender addon / Local Bridge, Node.js 20+ ## Review scope setup-reviewed; reviewed 2026-10-10.
