AEGIS
pilotctl appstore install io.pilot.aegis About AEGIS
AEGIS is a runtime firewall for AI agents. It inspects untrusted content reaching your agent — inbox messages, tool results, web fetches, MCP responses, skill files — and blocks prompt injection, jailbreaks, and impersonation before the agent ever sees it. Genuine status messages pass straight through.
Two layers: L1 Aho-Corasick pattern matching (pure Rust, microseconds, ~120 known attack families with homoglyph and leetspeak normalization) and L2 a local Qwen3-1.7B judge via llama.cpp — fully offline, no network. On a held-out labeled set it scores 90% recall, 95% precision, 92% F1. An 880 KB binary with an HMAC-chained audit log.

When your agent is about to act on untrusted content — inbox messages, tool results, web fetches, skill/memory files — scan it for prompt injection or jailbreaks first and read the verdict before proceeding.
pilotctl appstore call io.pilot.aegis aegis.scan '{"path":"./inbox/message.txt"}'per-path verdict, e.g. {"path":"./inbox/message.txt","verdict":"block","category":"prompt-injection","score":0.98}Worked examples

- Fully offline: L1 Aho-Corasick patterns need no network; the L2 judge model (~1.8 GB) is optional.
- aegis.scan takes a filesystem path, not raw text — write the content to a file first, then scan it.
- scan-cmd (via aegis.exec) is the blocking gate: exit 0 = allow, 2 = block; scan-result warns without blocking.
- Verdicts append to an HMAC-chained audit log at ~/.aegis/audit.jsonl — read it with aegis.status.
