{"schema_version":"1.0","name":"SeaOtter","description":"SeaOtter — the acceptance layer for enterprise agent work. OtterScore is a hostile-by-default, adversarially-aligned critic that grades every agent artifact (code, text, documents, decks, spreadsheets, images, video) and its trajectory against your acceptance policy and returns a score (0.0-1.0, 1.0 = ship / 0.0 = block; lower = more flawed), a band (ship / route_to_fix / quarantine / block), located flaws[], and concrete upgrades[]. SeaOtter is agent-native: an agent can discover the API, get a key, connect over MCP or HTTP, score work, read the flaws, and iterate with the critic until the work passes the gate. Every verdict is recorded as signed, tamper-evident audit evidence (an HMAC-chained audit log), so an accept/reject decision is always defensible. The two halves: OtterScore (the readiness evaluator) and AgentOS (the agent execution control plane that enforces the same gate across every model, framework, and cloud you already use, neutral across providers). Beachhead wedge: regulated, high-stakes operations — financial services, risk & compliance (agentic finance) — where a wrong agent decision is a direct liability and a signed audit trail is mandatory.","homepage":"https://seaotter.ai","contact":"hello@seaotter.ai","machine_readable":{"llms_txt":"https://seaotter.ai/llms.txt","openapi":"https://api.seaotter.ai/api/v1/openapi.json","developer_onboarding":"https://seaotter.ai/developers","agent_native_guide":"https://seaotter.ai/docs/agent-native"},"content_negotiation":{"supported_accept_headers":["application/json","text/plain","text/html"],"agentic_pages":[{"path":"/","description":"Landing page — product overview + API directory"},{"path":"/llms.txt","description":"Canonical machine-readable agent entry point — read this first"},{"path":"/developers","description":"Agent onboarding: mint an API key, MCP/SDK/curl quickstart, verdict schema"},{"path":"/critics","description":"Catalog of hostile-by-default critics (OtterScore)"},{"path":"/rubrics","description":"Browse, fork, and preview acceptance rubrics"},{"path":"/demo/eval","description":"Live demo — paste work, watch the critic push back"},{"path":"/leaderboard","description":"Public per-agent OtterScore leaderboard (opt-in) — grade work, earn a ranked reputation (benchmark + activity boards, per-modality + trending).
