tools by shubham

Small systems for running code safely, understanding GPU fleets, sharing operational files, and giving coding agents useful access without giving them the whole machine.

tools

Built to be inspected, self-hosted, and used in production.

Git

Forgejo · self-hosted public mirrors

Public mirrors for Sandbox, Watchman, and UltraBalancer, hosted at git.yshubham.com.

A read-only Forgejo kept synced with GitHub every two minutes and served behind Cloudflare.

git clone https://git.yshubham.com/bas3line/sandbox.git

Context Bridge

cb · local-first agent handoffs

A Rust CLI for moving useful coding-session context between OpenCode, Claude Code, and Codex without pretending hidden model state is portable.

It keeps a local canonical event log, checks Git state before a handoff, applies strict redaction, and launches the next agent through documented interfaces.

cargo install --git https://github.com/bas3line/Context-Bridge.git --locked cb-cli

Sandbox

v0.1.0 · control plane + cli

Disposable coding environments for humans and AI agents, without handing either of them the keys to the whole machine.

A self-hosted Rust control plane with risk-aware AEGIS scheduling, Docker workers, PostgreSQL, optional NATS, and a typed remote CLI.

curl -fsSL https://tools.yshubham.com/sandbox/setup.sh | sh

Watchman

v0.8.3 · cli

A fast operator's lens for GPU inference servers: inspect them, benchmark them, and catch trouble before users do.

An open-source Rust utility for monitoring, debugging, benchmarking, and safely operating production GPU inference infrastructure.

curl -fsSL https://tools.yshubham.com/watchman/install.sh | sh

Objects

R2 + Queues · screened public files

Temporary public URLs for small reports, screenshots, and images—without bucket access, listing, or an origin server.

Uploads are rate-limited, inspected at ingress, screened again by a Queue consumer, and only then promoted. Every download is forced as an inert attachment.

curl --fail-with-body --data-binary @report.json -H 'content-type: application/json' https://objects.yshubham.com/v1/objects

use with agents

Skills and protocols for operating the tools from coding agents.

  • skill

    sandbox-platform

    Sandbox lifecycle, risk signals, recovery, capacity diagnosis, and secret boundaries through CLI and MCP.

    npx skills add bas3line/rool-repo --skill sandbox-platform --agent '*' --global --yes
  • skill

    watchman

    GPU incidents, telemetry, canaries, capacity planning, benchmarks, history, and rollout validation.

    npx skills add bas3line/rool-repo --skill watchman --agent '*' --global --yes
  • mcp

    sandbox-mcp

    The Sandbox control plane exposed to coding agents through 12 lifecycle tools, 3 resources, and 2 prompts.

    codex mcp add sandbox -- sandbox-mcp
  • skill

    objects-storage

    Upload small, screened reports and images through a Queue-gated R2 object API without exposing bucket paths or origin credentials.

    curl --data-binary @report.json -H 'content-type: application/json' https://objects.yshubham.com/v1/objects
