Input Channels

  • Telegram bot — voice, images, history, /new
  • Discord bot — threads, attachments, interactive coding sessions
  • Web dashboard — audit, cron, usage, templates, skills
  • CLI — start, stop, onboard, tools, cron

Core Runtime

  • Fastify gateway on :18790 with bearer auth
  • Agent runner with tool loop, history, and memory
  • Unified provider router (Anthropic / Codex / OpenAI-compat)
  • Cron scheduler + heartbeat keep-alive

Tools

  • Read, Write, Glob, Bash, Fetch + Playwright browser
  • Path-scoped to allowedPaths — no free filesystem access
  • MCP tools auto-discovered via mcporter

Safety Gate

  • Exec approval classifies bash commands tier 0–3
  • Tiers 2–3 pause and require human approval
  • Approval requests route to the active channel

Coding Agents

  • code_with_agent spawns Claude, Codex, or Kimi CLI
  • Monorepo-aware validation scoped to changed packages
  • Live stdout streaming + cost / token tracking
  • Discord threads: bidirectional claude --resume sessions

Local Storage

  • Config at ~/.skimpyclaw/config.json (0600 perms)
  • JSONL logs: audit, usage, code-agents, interactive-sessions
  • Skills at ~/.skimpyclaw/skills/<name>/SKILL.md
  • Agent templates at ~/.skimpyclaw/agents/<name>/

External APIs

  • Anthropic (Claude Opus / Sonnet / Haiku) — OAuth or API key
  • Codex backend via ChatGPT responses endpoint
  • Any OpenAI-compatible provider (OpenRouter, Groq, Together)
  • MCP servers auto-discovered via mcporter
