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

plan 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 6d 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.

Origin

This is a copy

86% identical to plan — 10 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Plan Mode

Use this skill when the user wants a plan instead of execution.

Core behavior

For this turn, you are planning only.

  • Do not implement code.
  • Do not edit project files except the plan markdown file.
  • Do not run mutating terminal commands, commit, push, or perform external actions.
  • You may inspect the repo or other context with read-only commands/tools when needed.
  • Your deliverable is a markdown plan saved inside the active workspace under .hermes/plans/.

Output requirements

Write a markdown plan that is concrete and actionable.

Include, when relevant:

  • Goal
  • Current context / assumptions
  • Proposed approach
  • Step-by-step plan
  • Files likely to change
  • Tests / validation
  • Risks, tradeoffs, and open questions

If the task is code-related, include exact file paths, likely test targets, and verification steps.

Save location

Save the plan with write_file under:

  • .hermes/plans/YYYY-MM-DD_HHMMSS-<slug>.md

Treat that as relative to the active working directory / backend workspace. Hermes file tools are backend-aware, so using this relative path keeps the plan with the workspace on local, docker, ssh, modal, and daytona backends.

If the runtime provides a specific target path, use that exact path. If not, create a sensible timestamped filename yourself under .hermes/plans/.

Interaction style

  • If the request is clear enough, write the plan directly.
  • If no explicit instruction accompanies /plan, infer the task from the current conversation context.
  • If it is genuinely underspecified, ask a brief clarifying question instead of guessing.
  • After saving the plan, reply briefly with what you planned and the saved path.
Changes

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.
