Description
Manage Time-To-Live policies for framework content freshness

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

| Type | TTL (days) | Rationale | |------|------------|-----------| | Protocol/Standard | 90 | Core protocols are stable | | API Documentation | 60 | Interfaces change moderately | | Configuration | 30 | Configs need frequent updates | | Roadmap/Timeline | 14 | Time-sensitive | | Security Policy | 90 | Security requires stability | | Decision Record | 180 | Decisions are long-lived | | Tutorial/Guide | 60 | Examples may need updates | | Reference Data | 30 | Data freshness matters |

Status States

🟢 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)

<!-- 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)

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

JSON

{
  "_prov": "https://github.com/ekson73/multi-agent-os/blob/main/protocols/hmp.md|v1.0|2026-01-07|TTL90|exp:2026-04-07"
}

PROV Fields

| Field | Format | Example | |-------|--------|---------| | full-url | GitHub URL | https://github.com/.../file.md | | version | Semver | v1.0 | | sync | ISO date | sync:2026-01-07 | | TTL | Days | TTL:90d | | exp | ISO date | exp:2026-04-07 |

Agent Actions by Status

| Status | Agent Action | Human Action | |--------|--------------|--------------| | 🟢 FRESH | Use normally | None needed | | 🟡 EXPIRING | Warn human | Schedule review | | 🔴 EXPIRED | Block, require refresh | Sync from upstream |

Sync Protocol

When content is EXPIRED:

  1. Check upstream for updates
  2. Pull latest version
  3. Update sync date
  4. Recalculate expiration
  5. Update PROV tag
