Facio's Inline Learning: How Agents Update Their Own Memory During Every Conversation

Facio's Inline Learning: How Agents Update Their Own Memory During Every Conversation

Most AI agents start fresh every session. Facio agents update their own memory files — MEMORY.md, BUGS.md, USER.md — in real time during conversations, using surgical edits that keep the knowledge base clean and current. Here's how inline learning works, when agents write to memory, and why this architecture produces better long-term behavior than RAG alone.

Facio's HITL Tool Suite: How ask_approval, ask_form, and ask_selection Keep Humans in Control

Most agent platforms treat human approval as a binary step: approve or reject. Facio's HITL tools — ask_approval, ask_form, ask_selection, and ask_text_input — turn human-agent interaction into structured workflows with custom options, password-gated credential capture, markdown review, and timeout handling. Here's how each tool works and when to use it in production.

Facio's Spawn System: How Parallel Sub-Agents Multiply Agent Throughput

Facio's Spawn System: How Parallel Sub-Agents Multiply Agent Throughput

Gartner predicts 40% of agentic AI projects will be cancelled by 2027 due to escalating costs. One reason: most agent platforms run tasks sequentially. Facio's spawn system lets agents delegate work to parallel sub-agents — each with isolated context, optional model overrides, and direct filesystem access — and collect results asynchronously. Here's how the architecture works and when to use it.

Facio's Built-in Browser: How AI Agents Navigate the Web Without External Infrastructure

Most AI agent platforms require a separate Playwright container, a CDP proxy, or a third-party browser service just to visit a webpage. Facio ships with a full browser automation suite built into the runtime — persistent sessions, accessibility snapshots, screenshots, and HITL gating. Here's how the architecture works and why it matters for production agent workflows.

How Facio's Credential Store Prevents AI Agent Secret Leaks at Runtime

How Facio's Credential Store Prevents AI Agent Secret Leaks at Runtime

In 2025 alone, nearly 29 million new secrets were found hardcoded in public GitHub commits — and AI-assisted code leaks at double the rate. Facio's credential store solves this by ensuring agents never touch raw API keys. Here's how the architecture works, from password-gated setup to write-time placeholder resolution to full audit trail coverage.
