Hermes Agent v0.8.0

🔔 Background Auto-Notifications

Long-running tasks notify the agent on completion. No polling needed — the agent keeps working and picks up results when they land.

🎛️ Live Model Switching

/model command works across CLI, Telegram, Discord, Slack. Switch providers mid-session with interactive pickers.

🧠 Self-Optimized GPT/Codex

Agent diagnosed and patched 5 failure modes through automated behavioral benchmarking. Dramatically improved OpenAI reliability.

🆓 Free MiMo v2 Pro

Xiaomi MiMo v2 Pro now available on Nous Portal free tier for auxiliary tasks (compression, vision, summarization).

⏱️ Smart Inactivity Timeouts

Timeouts track actual tool activity, not wall-clock time. Active tasks never killed — only truly idle agents time out.

✅ Approval Buttons

Slack & Telegram get native platform buttons for dangerous command approval. No more typing /approve.

Self-Optimized Tool Use

Agent ran automated behavioral benchmarks on GPT/Codex, identified 5 failure modes, and patched them with execution discipline guidance.

Thinking-Only Prefill

Structured reasoning responses with thinking block continuation. Accept reasoning-only responses without infinite retries.

Jittered Retry Backoff

Exponential backoff with jitter for API retries. Prevents thundering herd on rate limits.

Oversized Tool Results

Save to file instead of destructive truncation. Sandbox-aware persistence keeps context intact.

Config Structure Validation

Detect malformed YAML at startup with actionable error messages. Catches issues before cryptic failures.

Centralized Logging

Interactive CLI Improvements

Defer response until reasoning completes. Ghost status-bar lines cleared on resize. Native Windows image paste support.

Doctor Diagnostics

Sync provider checks, config migration, WAL and mem0 diagnostics. Timeout debug logging improved.

Inactivity-Based Timeout

Replaces wall-clock timeout. Active tasks run indefinitely — only truly idle agents time out.

Pre-Run Script Injection

Data collection and change detection before cron runs. Helps agent understand what changed since last run.

Delivery Failure Tracking

Job status includes delivery failures. Delivery guidance in prompts stops send_message thrashing.
