Sponsio is a Python/TypeScript runtime safety layer for LLM agents: it evaluates deterministic contracts against each tool call and can block (enforce) or just log (observe) violations. (LLM-judged stochastic contracts — tone, prompt-injection, semantic PII, scope respect — are a Sponsio Cloud feature available via pip install sponsio[cloud]; the OSS engine is det-only.) This skill covers the full lifecycle — first-time setup, contract authoring/review, observe-mode tuning, and flipping to enforce — by orchestrating Sponsio's CLI and explaining its output in plain language.
Sponsio is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/sponsio/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when the user wants to set up / add / install Sponsio, add guardrails or runtime safety to an LLM agent, generate or refine a sponsio.yaml, audit tool configurations for risks (data leaks, unguarded writes, missing confirmations), explain or review existing contracts, check what Sponsio would have blocked (`sponsio report`), refresh the contract library from recent traces (`sponsio refresh`), move from observe to enforce mode, or debug why a contract is (or isn't) firing.
The Sponsio skill is built for Claude Code users and developers across all disciplines looking for general-purpose AI assistance. It is part of the open ClaudSkills registry, a community-curated catalog of 56,000+ capabilities you can install for Claude Code — the Claude CLI agent.
mkdir -p ~/.claude/skills/sponsio curl -L https://claudskills.com/skills/sponsio/SKILL.md \ -o ~/.claude/skills/sponsio/SKILL.md
Or just download SKILL.md directly and drop it into ~/.claude/skills/sponsio/. Claude Code auto-discovers it on next session.
Skills live at ~/.claude/skills/sponsio/SKILL.md on macOS/Linux, or %USERPROFILE%\.claude\skills\sponsio\SKILL.md on Windows. See the full install guide for step-by-step instructions.
