Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

PVYai is an AI coding agent for your local terminal. It can inspect a repository, edit files, run commands, use browser/terminal helpers, and keep durable local sessions while you choose the model and the permission level.

pvyai
pvyai exec "fix the failing test in ./pkg"
pvyai exec --output-format stream-json < turns.jsonl

Why PVYai Agent

  • Use the model you want. Bring PVYai, OpenAI, Anthropic, Gemini, Groq, OpenRouter, DeepSeek, Mistral, xAI, Qwen, Kimi, GitHub Models, Ollama, LM Studio, or any OpenAI-/Anthropic-compatible endpoint.
  • Stay in control. File writes, shell commands, network access, and out-of-workspace writes go through PVYai Agent permission and sandbox policy.
  • Works in the terminal. The TUI has model/provider pickers, image input, slash commands, live plan/tool rendering, scrollback, themes, and resume/fork support.
  • Works without the TUI. pvyai exec is scriptable, supports text/JSON/ stream-JSON I/O, isolated worktrees, spec-first runs, and meaningful exit codes for CI.
  • Keeps context local. Sessions are stored on disk, searchable, resumable, and never uploaded as telemetry by PVYai.
  • Extensible when you need it. Use local MCP servers, skills, plugins, hooks, and specialist subagents from the same CLI.
  • PVYai Sentinel integration. PVYai Sentinel watch and simulates the outcome of your LLM interations in real time, and prevents harmful actions before LLM can execute.
  • PVYai Memory integration. PVYai Memory offers for PVYai LLM Models automatic and manual Memory management for findings, session handover, iniated and monitored by PVYai Sentinel Intelligence. It offers users Private Memory Wing or allocated Primary Shared Memory, Secondary Shared Memory and Third, for interdisciplinary cross-domain preservation.
  • PVYai Sentinel Orchestration. As an Orchestrator, he manage your Team Agents and evict and re-onboard them automatic based on real-time metrics instead of classical turn/tool call count.
  • PVYai Unified SSE API. Chosing PVYai as Provider, drives our sophisticated, OpenAI API compatible, unified SSE Stream API, which offers native function call for our MCP Services. Your PVYai Agent can execute all tools offered in parallel instead of serial curl commands, also the Specialists/Sub-agents.

Install

npm

npm install -g @pvyswiss/pvyai-agent
pvyai

The npm package installs a small wrapper plus the matching PVYai binary for your platform from GitHub Releases. It supports Linux, macOS, and Windows on x64 and arm64.

Bun

Bun does not run dependency lifecycle scripts by default, so the postinstall that fetches the PVYai binary is skipped and the first run fails with No native binary found next to the npm wrapper.

The simplest fix is to trust the package after installing, which runs the blocked postinstall. This works for project and global installs:

# project install
bun add @pvyswiss/pvyai-agent
bun pm trust @pvyswiss/pvyai-agent

# global install
bun add -g @pvyswiss/pvyai-agent
bun pm -g trust @pvyswiss/pvyai-agent

Alternatives: allow the postinstall up front by adding "trustedDependencies": ["@pvyswiss/pvyai-agent"] to your project's package.json before bun add, or run the installer manually (node node_modules/@pvyswiss/pvyai/scripts/postinstall.mjs) on Bun versions that do not have bun pm trust.

Install scripts

Linux/macOS:

curl -fsSL https://raw.githubusercontent.com/pvyswiss/pvyai-coding-agent/main/scripts/install.sh | bash

Windows PowerShell:

irm https://raw.githubusercontent.com/pvyswiss/pvyai-coding-agent/main/scripts/install.ps1 | iex

From source

Source builds require Go 1.25+.

git clone https://github.com/pvyswiss/pvyai-coding-agent.git
cd pvyai-coding-agent
go run ./cmd/pvyai

Release installers and the npm wrapper require published GitHub Release assets. If you are testing before the first public release, build from source:

go build -o pvyai ./cmd/pvyai

On Linux, build the sandbox helper too if you want native sandboxing:

go build -o pvyai-sandbox ./cmd/pvyai-linux-sandbox
go build -o pvyai-seccomp ./cmd/pvyai-seccomp   # optional compatibility wrapper

Put pvyai and pvyai-sandbox in the same directory on PATH (~/.local/bin is a good default). macOS does not need an extra helper binary. Windows source builds can use the main pvyai.exe as their sandbox helper; release archives still ship standalone Windows helper executables.

More install details: docs/INSTALL.md.

First Run

Start the TUI:

pvyai

The setup wizard helps you pick a provider and model. You can also configure providers from the command line:

pvyai setup
pvyai providers list
pvyai models list
pvyai doctor

For API providers, set the matching environment variable before setup or enter the key in the wizard:

export OPENAI_API_KEY=sk-...
export ANTHROPIC_API_KEY=...
export GEMINI_API_KEY=...
export LONGCAT_API_KEY=...

To configure Meituan LongCat (LongCat-2.0) directly, run:

pvyai providers setup longcat --set-active

For local models, run Ollama or LM Studio and then use pvyai setup or pvyai providers detect.

Daily Use

Interactive TUI

pvai

Useful controls:

| Control | Action | | ----------- | ------------------------------ | | Enter | send the prompt | | / | open slash-command suggestions | | Shift+Tab | cycle permission mode | | Ctrl+X | show/hide the sidebar | | Ctrl+C | cancel or exit |

Common slash commands:

| Command | Purpose | | ------------------------------ | ----------------------------------------------- | | /model, /provider | switch the active model/provider | | /spec, /plan | draft and review a plan before building | | /image | attach an image for vision-capable models | | /resume, /rewind | continue or roll back local sessions | | /compact, /context | manage context usage | | /permissions, /tools | inspect available tools and policy | | /add-dir | allow an extra write directory for this session | | /theme, /doctor, /config | adjust appearance and inspect setup |

Headless exec

pvyai exec "explain internal/agent/loop.go"
pvyai exec --model claude-sonnet-4.5 "refactor the config loader"
pvyai exec --use-spec "add rate limiting to the API client"
pvyai exec --worktree "try the migration in an isolated worktree"
pvyai exec --resume
pvyai exec --fork <session-id> "try the other approach"

Programmatic use:

pvyai exec --input-format stream-json --output-format stream-json < turns.jsonl

The stream-JSON contract is documented in docs/STREAM_JSON_PROTOCOL.md.

Safety Model

PVYai is designed to make side effects visible.

  • Workspace reads are allowed by default.
  • File writes are limited to the workspace unless you grant another directory.
  • Shell commands, network access, destructive commands, and elevated actions are permission-gated.
  • --add-dir <path> and /add-dir <path> grant additional write roots without giving the agent the whole filesystem.
  • Unsafe/autonomous modes are explicit opt-ins.
  • Secrets are redacted from tool output and logs where PVYai controls the surface.
  • PVYai Sentinel Real World Model watches, predicts and simulate real action outcome, blocks harfmul action before LLM can execute it (Only for PVYai as Provider, but Anthropic Models included)

Example:

pvyai --add-dir ../docs-site
pvyai exec --add-dir ../shared "update both repos"

Sandbox behavior can be inspected with:

pvyai sandbox policy
pvyai sandbox grants list

Web And Local Control

PVYai includes local file/search/edit/shell tools, web_fetch for public URLs, and MCP support for additional tools.

For local dev servers, use shell commands such as curl through exec_command so the normal sandbox and permission policy applies. Long-running commands stay attached to a background terminal session and can be listed or stopped from the TUI.

The npm package also includes browser and terminal helper packages used by local browser/terminal tools. Source builds can use the same helpers when they are on PATH or configured in PVYai's local-control settings.

Extending PVYai

Project and personal instructions

PVYai appends project-specific guidance to the system prompt from the first AGENTS.md, PVYAI.md, or .pvyai/AGENTS.md file found in each directory from the git root down to your current working directory (checked in that order per directory). Files are injected general-to-specific, capped at 8 KiB per file and 32 KiB total.

A personal PVYAI.md under config.UserConfigDir()/pvyai/PVYAI.md ($XDG_CONFIG_HOME/pvyai/PVYAI.md or ~/.config/pvyai/PVYAI.md on Linux/macOS, %AppData%\Roaming\pvyai\PVYAI.md on Windows) applies across every workspace, ahead of any project guidelines.

Plugins

Plugins are discovered from ~/.config/pvyai/plugins/<name>/plugin.json (user scope — $XDG_CONFIG_HOME or ~/.config on every OS, independent of the config.UserConfigDir() path used above) and <cwd>/.pvyai/plugins/<name>/plugin.json (project scope — resolved from the current working directory, not the repo root), and managed with pvyai plugins. A manifest can declare:

  • tools — custom tools (command, args, inputSchema, and a permission of prompt or deny; allow is honored only when manifest tool auto-approval is enabled)
  • hooks — commands run on beforeTool, afterTool, sessionStart, or sessionEnd
  • prompts and skills — additional prompt/skill files

MCP servers (pvyai mcp) and standalone markdown skills (pvyai skills) use the same extension points and can also be wired up outside of a plugin manifest.

Appearance And Accessibility

| Control | Effect | | --------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | NO_COLOR=<anything> | disables color output | | PVYAI_THEME=<name> | selects the startup theme (auto, dark, light, or a color theme like dracula, nord, gruvbox, tokyo-night, catppuccin, one-dark, solarized-dark, rose-pine, everforest, solarized-light) | | --theme <name> | selects the TUI theme from the CLI (same names) | | /theme | opens the theme picker inside the TUI (live preview; /theme <name> switches directly) | | PVYAI_NO_FADE=1 | disables streaming fade animation |

Meaning does not rely on color alone; diffs, permissions, and statuses also use text or glyph markers.
