omh-browser is a skill for Claude Code, Codex from rlaope/oh-my-hermes. It costs 72 tokens per session (1,594 once invoked), scanned A, original, MIT.

A workflow for operating a web browser through the Hermes system while recording the required context, actions, and evidence boundaries.

In plain words
What is it for?
Use it to navigate a staging website, fill in forms, capture blockers, and document missing authority, credentials, targets, or evidence.
Why use it?
It keeps browser tasks structured and makes clear what was prepared or observed, without claiming that external actions happened when they were not verified.

About the project

oh-my-hermes is an operating layer for Hermes Agent that organizes requests into workflows for planning, research, creation, coding handoffs, operations, and project memory. Hermes users run these workflows through the desktop app, CLI, or messenger app, while the catalogue add-ons extend its native capabilities.

    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

omh-browser 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 yesterday.

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.

Browser Operator

This is a Hermes-native browser-operator workflow skill.

Why This Exists

browser-operator exists so Hermes users can ask for this workflow in chat and receive a structured, evidence-bounded OMH operating surface instead of ad hoc narration.

Do Not Use When

  • The request is already handled by a narrower explicit skill with stronger evidence.
  • The user asks OMH to secretly run external platforms, connectors, schedulers, file exports, or runtime agents.
  • The only safe answer is to ask for missing authority, credentials, target, or observed evidence first.

Examples

Good example:

  • Prompt: browser-operator open the staging checkout URL, click login, fill the form, and capture blockers.
  • Expected behavior: Produce prepare_browser_operator_card with required context, wrapper actions, and not-evidence boundaries.
  • Why: The prompt names a real workflow surface that Hermes can orchestrate without hiding execution.

Bad example:

  • Prompt: browser-operator use saved credentials and submit the production payment form without confirmation.
  • Expected behavior: Report the missing observed evidence or authority instead of claiming the external step happened.
  • Why: Prepared OMH guidance is not platform, runtime, connector, file, memory, or delivery evidence.

Completion Checklist

  • Specify URL, allowed/prohibited actions, auth boundary, stop condition.
  • Gate credentials/login/payment/purchase/destruction/scraping/export; observed traces only.
  • Host request admission (not enablement/adapter presence) gates schemas/context/callbacks/writes. Refuse foreign/stale/expired/released/ambiguous targets; no index fallback.
  • omh_browser blocks native browser_*; inert by default. Opted-in effects need exact approval: docs/BROWSER-EFFECTS.md.

Recovery Notes

  • Missing target/confirmation: ask; visual correctness: visual-qa.
  • Refresh stale state once; never replay unknown work. Reuse acquisitions; only owner adapter/version reaps. Release needs observed cleanup, not mutation approval.
  • Host receipt BLOCK: production click/submit, retry after auth/4xx/assertion/mutation failure, or over two transient read-only retries.
  • POSIX native agent-browser collector: cold-desktop anonymous read-only Chromium only; other engine/profile/fixture/locale/timezone: named blocker (unsupported_browser_engine_webkit), never substitution.
  • Trace drift: promotion status unlinks only managed SKILL.md, keeps generations/receipts; no autoheal/watch/global fallback.

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.
