TTL Policy Skill

Purpose

Manage Time-To-Live (TTL) policies for content consumed from the multi-agent-os framework. Ensures information freshness and triggers review cycles when content expires.

When to Use

• When consuming content from framework
• When checking document freshness
• When syncing from upstream
• When reviewing stale content

TTL by Content Type

Status States

Copy🟢 FRESH    → now < expires - 7d    → Use normally
🟡 EXPIRING → expires-7d < now < expires → Alert, plan review
🔴 EXPIRED  → now >= expires        → Block usage, require refresh

PROV Tag Format

Add provenance tracking to consumed content:

Compact (1-line)

Copy<!-- PROV: https://github.com/ekson73/multi-agent-os/blob/main/protocols/hmp.md | v1.0 | sync:2026-01-07 | TTL:90d | exp:2026-04-07 -->

Inline (Markdown-safe)

Copy[//]: # (PROV: https://github.com/ekson73/multi-agent-os/blob/main/protocols/hmp.md|v1.0|2026-01-07|TTL90|exp:2026-04-07)
