plan

plan is a command for coding agents from 0xhimanshu/governor. It costs 14 tokens per session (286 once invoked), scanned A, original, MIT.

A planning command that creates a written implementation contract before a large app, website, game, or refactoring task.

In plain words
What is it for?
Use it to outline research assumptions, architecture, implementation phases, acceptance tests, and conditions for stopping. The developer approves the plan before implementation.
Why use it?
It turns a broad request into agreed requirements, design decisions, files, tests, and limits before coding starts.

Command

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

Install

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.

agentmods
npx agentmods add commands/0xhimanshu/governor/plan
Clone the repo
git clone --depth 1 https://github.com/0xhimanshu/governor

Or install governor, the plugin that ships this one along with the rest of its 1 skill, 11 commands, 5 hooks.

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 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.

What it actually says

Governor Plan

Create an implementation contract for $ARGUMENTS. This command is explicit opt-in governance: do not implement yet.

Use bounded research when facts are current or market/design/API dependent. Keep research compact and cite sources when browsing.

Return a contract with:

  • product concept and audience
  • key research facts or assumptions
  • brand/theme/storyline
  • UI strategy and responsive states
  • architecture and data model
  • implementation phases
  • planned files or file areas
  • acceptance tests
  • drift guardrails
  • stop conditions

At the end, include a JSON contract block with these keys:

{
  "title": "",
  "goal": "",
  "requirements": [],
  "planned_files": [],
  "acceptance_tests": [],
  "drift_guardrails": [],
  "stop_conditions": []
}

Also save the same JSON contract into plugin data before returning:

python3 "${CLAUDE_PLUGIN_ROOT}/scripts/governor.py" save-contract --title "SHORT TASK TITLE"

Pass the JSON on stdin. The helper generates a safe lowercase slug.

Tell the user implementation should begin only after they approve the contract. Do not make /governor:plan a hidden prerequisite for small focused fixes.

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.
