Package Exports

  • @spryv/agent

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@spryv/agent) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Spryv Agent

The autonomous coding agent that works with any model.

Give Spryv a task. It explores your codebase, diagnoses the root cause, writes the fix, runs the tests, and reports back — without you steering every step. The full autonomy of Claude Code, with the freedom to use any model you choose.

Why Spryv

Model freedom — the thing the others don't give you

Claude Code works only with Claude. Cursor locks you to their subscription. Spryv works with any OpenAI or Anthropic-compatible API — Claude, Gemini, DeepSeek, Kimi K2, any model on OpenRouter, Vertex AI, or a private self-hosted endpoint. Swap providers with a single flag. No lock-in, no walled garden, no subscription.

spryv --provider deepseek "refactor the payment module"
spryv --provider gemini "fix the race condition in the auth flow"
spryv --provider openrouter "add rate limiting to the API"

Full agent architecture — not a chat wrapper

Spryv runs a structured loop modeled on how a senior engineer actually works:

  1. Explore — reads relevant files, maps call graphs, traces execution paths
  2. Plan — builds an explicit plan before touching anything; reasoning is visible
  3. Execute — implements changes through an architect review pass before applying each patch
  4. Verify — runs tests, confirms results, reports exactly what changed and why

At every iteration it maintains a live state tree: confirmed facts, pending tasks, in-progress changes, sub-agent status. A health-check monitor detects loops and stalls and nudges the agent back on track.

Sub-agents and skills — built-in extensibility

Spawn parallel specialized sub-agents for exploration, planning, or code review. Each sub-agent gets its own context, tools, and iteration budget. Results merge back into the main session. Define custom agents and /slash-command skills in Markdown files — no code required.

Three interfaces, one engine

VS Code extension with a full chat panel, standalone Electron desktop app with a live state tree sidebar, and a CLI with phase-gated output. Same engine, same sessions, same capabilities across all three.

Install

VS Code

ext install faisalsalamah.spryv

Or install from the Marketplace / download .vsix from Releases.

CLI (Node.js 18+)

spryv --chat --resume <session-id>                  # resume a session
spryv --provider deepseek "fix the memory leak"    # switch provider
spryv --verbose "refactor the auth module"          # verbose output
