1c-ssl-skills: Skill for Claude Code

.agents/skills/hosted-agents/SKILL.md

hosted-agents is a skill for Claude Code, Codex from brake71/1c-ssl-skills. It costs 46 tokens per session (3,401 once invoked), scanned A, a copy of hosted-agents, MIT.

A design guide for agents that run in remote, isolated environments instead of on a developer's computer. It covers persistent sessions, shared work, parallel agents, and sandboxed execution.

In plain words
What is it for?
It helps build hosted coding agents, remote execution environments, background workers, shared agent sessions, and systems that start additional agents for parallel tasks.
Why use it?
Local machines limit where background agents can run and how many tasks they can handle at once. Remote sandboxes provide separate environments for independent or collaborative work.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: mentions subagents; installed under .agents/ (shared by several agents); mentions OpenCode.

This is brake71/1c-ssl-skills's own configuration. It tells Claude Code and Codex how to work on 1c-ssl-skills itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything 1c-ssl-skills configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

hosted-agents scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 17d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/sandbox_manager.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Hosted Agent Infrastructure

Hosted agents run in remote sandboxed environments rather than on local machines. When designed well, they provide unlimited concurrency, consistent execution environments, and multiplayer collaboration. The critical insight is that session speed should be limited only by model provider time-to-first-token, with all infrastructure setup completed before the user starts their session.

When to Activate

Activate this skill when:

  • Building background coding agents that run independently of user devices
  • Designing sandboxed execution environments for agent workloads
  • Implementing multiplayer agent sessions with shared state
  • Creating multi-client agent interfaces (Slack, Web, Chrome extensions)
  • Scaling agent infrastructure beyond local machine constraints
  • Building systems where agents spawn sub-agents for parallel work

Do not activate this skill for adjacent work owned by other skills:

  • Designing the autonomous research loop, novelty gates, rollback policy, or merge boundaries: harness-engineering.
  • Choosing supervisor, swarm, or handoff topology without hosted infrastructure concerns: multi-agent-patterns.
  • Designing the tools used by a hosted agent, such as spawn/status tools or PR tools: tool-design.
  • Managing file-backed state inside a session rather than the hosted runtime itself: filesystem-context.

Core Concepts

Move agent execution to remote sandboxed environments to eliminate the fundamental limits of local execution: resource contention, environment inconsistency, and single-user constraints. Remote sandboxes unlock unlimited concurrency, reproducible environments, and collaborative workflows because each session gets its own isolated compute with a known-good environment image.

Design the architecture in three layers because each layer scales independently. Build sandbox infrastructure for isolated execution, an API layer for state management and client coordination, and client interfaces for user interaction across platforms. Keep these layers cleanly separated so sandbox changes do not ripple into clients.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
