Hermes Agent is an AI assistant that learns from its use by creating and improving skills, retaining knowledge, searching past conversations, and adapting to its users. It is for people who want to run an agent through a terminal or messaging platforms while connecting it to different AI models and scheduled tasks.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00015 | $0.00784 |
| Opus 5 | $0.00008 | $0.00392 |
| Sonnet 5 | $0.00003 | $0.00157 |
| Haiku 4.5 | $0.00002 | $0.00078 |
Grade A, and why
agentmail scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

AgentMail Skill
AgentMail gives an agent its own email inbox for sending mail, receiving replies, completing email OTP flows, and running inbound email loops. Use it for agent-owned inboxes, not a user's existing IMAP/SMTP mailbox.
Use the agentmail CLI first. Use MCP only when the harness expects MCP tools;
use REST only when the CLI is missing a required operation.
When to Use
- The agent needs an email address it owns.
- The task involves email OTP flows, replies, threads, labels, or attachments.
- The agent needs webhook or WebSocket delivery for inbound mail.
Prerequisites
- Run commands through the
terminaltool. - Install the CLI:
npm install -g agentmail-cli@latest
- Export an API key:
export AGENTMAIL_API_KEY="am_..."
No API key yet? Use signup.md.
How to Run
Use --format json whenever another command or script needs IDs.
agentmail inboxes list --format json
Quick Reference
- AgentMail agent reference: hosted copy.
- AgentMail: product landing page.
- Console: API keys and account management.
- Docs: full product documentation.
- signup.md: self-signup and OTP verification.
- core.md: inboxes, messages, threads, labels, attachments.
- webhooks.md: events to a public HTTPS server.
- websockets.md: events to a local agent process.
- mcp.md: MCP integration.
Procedure
- Install
agentmail-cli@latestand verifyagentmail inboxes list --format json. - If no API key is available, complete signup.md.
- Use core.md for inbox, send, read, reply, forward, label, thread, and attachment flows.
- Add webhooks.md or websockets.md only when polling is not enough.
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

agentmail is a skill published in the GitHub repository NousResearch/hermes-agent (240,739 stars, last pushed yesterday), licensed MIT. It adds 15 tokens to every session and 784 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

memory-triage
Persistent long-term memory protocol powered by mem0. Evaluate conversations for durable facts worth storing via memoryadd. Handles identity, preferences, decisions, configurations, rules, projects, and relationships. Loaded by the openclaw-mem0 plugin when skills mode is active.
mem0-dream
Consolidates stored memories by merging duplicates, resolving contradictions, and pruning stale entries. Use when memory count is high, search results feel noisy or repetitive, or periodic cleanup is needed to maintain memory quality.
mem0-tour
Browses all stored memories grouped by category with full content display. Use when reviewing all project memories, exploring stored knowledge, onboarding to a project, or getting an overview of captured decisions, conventions, and learnings.
onboard
Sets up mem0 for a new project including API key configuration, MCP authentication, project file import, and coding categories. Use on first run in a new project, when API key needs updating, or to re-run initial setup after configuration changes.
mem0-vercel-ai-sdk
Mem0 provider for Vercel AI SDK (@mem0/vercel-ai-provider). TRIGGER when: user mentions "vercel ai sdk", "@mem0/vercel-ai-provider", "createMem0", "retrieveMemories", "addMemories", "getMemories", "searchMemories", "mem0 vercel", "AI SDK provider", "AI SDK memory", or is using generateText/streamText with mem0. Also…
mem0-scope
Views or changes the default memory scope (project, session, or global) used when saving and searching memories. Use when the user wants to control whether memories are scoped to this repo, this run, or shared across all their projects.
