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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00046 | $0.03473 |
| Opus 5.5 | $0.00018 | $0.01389 |
| Sonnet 5.5 | $0.00009 | $0.00695 |
| Haiku 4.5 | $0.00005 | $0.00347 |
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 1mo ago.
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.
This is a copy
95% identical to hosted-agents — 6 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 308 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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.
Local safety overlay: bundled Python and shell fragments are architectural examples, not trusted entry points. Do not execute them automatically. Use argv-based subprocess APIs, keep credentials out of clone URLs and process listings, validate repository/identity inputs, and preserve human approval for pushes, deployments, credentials, and destructive lifecycle operations.
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.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

hosted-agents is a skill published in the GitHub repository docxology/template (20 stars, last pushed today), licensed Apache-2.0. It adds 46 tokens to every session and 3,473 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 95% identical to hosted-agents, differing in 6 lines, and is treated as a copy.
