About

Connect your Hermes agent to Slack. Post messages to channels, read recent messages, create threads, upload files and respond to mentions — all without leaving your agent workflow.

Use Cases

  • Post automated status updates to a team channel
  • Alert the on-call engineer when a monitored service goes down
  • Summarise overnight Slack activity every morning

What Slack Integration can access

Broad access

Read this skill's SKILL.md in full before installing it. Run it against a disposable host or test account first, and give it the narrowest credentials that still work.

  • Needs your credentials

    You must supply secrets for this skill to work. A skill with a valid key can do anything that key permits, so scope each one as narrowly as the provider allows and never reuse an admin key.

    Declares 1 required credential: SLACK_BOT_TOKEN

  • Reads or writes your files

    It works with files on disk. Consider which directories the agent process can actually reach.

    This skill's own description refers to "file"

  • Sends messages as you

    It can send messages from your account. Anything it sends will look like it came from you, so mistakes are visible to other people.

    This skill's own description refers to "slack"

  • Makes outbound network calls

    It contacts external services. Outbound calls are how data leaves your machine, so it is worth knowing where it connects.

    This skill's own description refers to "integration"

These permissions are inferred from this listing — the credentials it declares, any maintainer warning, and the operations its own description mentions. ClawVault has not audited this skill's source code. Treat it as a starting point for your own review, not a substitute for one.

Installing Slack Integration on Hermes Agent

Hermes skills are on-demand knowledge documents stored in hermes/skills/, which is the single source of truth. Bundled skills are copied there on a fresh install, and hub-installed and agent-created skills land there too. Every installed skill automatically becomes a slash command, so a skill named plan is invoked with /plan.

  1. 1

    Search for the skill

    hermes skills search slack

    Add --source to widen the search: official for curated skills, skills-sh for the public skills.sh directory, browse-sh for site-specific browser automation, or well-known to point Hermes at a site publishing its own skill index.

  2. 2

    Inspect it before installing

    hermes skills inspect official/<category>/slack

    inspect shows the skill's contents and metadata. Use the fully qualified identifier that search returned, which includes its source and category.

  3. 3

    Install it

    hermes skills install official/<category>/slack

    Identifiers are source-qualified, for example official/migration/openclaw-migration or skills-sh/anthropics/skills/pdf. You can also install straight from a URL that serves a SKILL.md. --force overrides non-dangerous policy blocks but will not override a dangerous scan verdict.

  4. 4

    Use it as a slash command

    /slack

    Installed skills become slash commands in any chat session. Run hermes skills list to see everything available, or /skills from inside a session.

Commands follow the official Hermes Agent documentation. Placeholders such as <owner> are filled in by the search step, because registry references are publisher-scoped.

How Hermes Agent screens skills

Hermes checks third-party and community skills against policy before installing, and --force will not override a verdict it considers dangerous. Because Hermes can also write its own skills at runtime, review what the Curator has kept periodically with hermes skills list.
