plan

plan is a skill for Claude Code, Codex from S3YED/appie-kit. It costs 35 tokens per session (457 once invoked), scanned A, a copy of plan, MIT.

A planning mode for Hermes, a coding agent. It creates a written plan in the workspace and stops without carrying out the planned changes.

In plain words
What is it for?
Use it to inspect a project, record assumptions, outline implementation steps, identify likely files and tests, and note risks or open questions.
Why use it?
It lets you agree on the approach and affected files before code is modified. This is useful when you need review or want to separate planning from execution.

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 3d 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

88% identical to plan — 5 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.
