plan

plan is a command for coding agents from atuljha23/holocron. It costs 30 tokens per session (354 once invoked), scanned A, original, MIT.

A planning command that puts a coding task into a structured plan before implementation begins. The plan covers the goal, success checks, risks, files involved, verification, and rollback.

In plain words
What is it for?
Use it before implementing a feature, fix, migration, or other substantial change. It helps organize exploration and define how the result will be verified.
Why use it?
It makes the intended work and its boundaries explicit before code changes start. This helps reveal missing requirements and gives non-trivial tasks a way to be checked and undone.

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.

What it actually says

/holocron:plan

Enter plan mode immediately. Do not start implementing. Use the scaffold below to organize your exploration and drafted plan.

If the user provided a task in $ARGUMENTS, treat that as the objective. Otherwise, ask what they want to accomplish.

Plan scaffold to fill in

## Context
<one paragraph: what problem this solves, what the trigger was, what outcome defines success>

## Success criteria
- [ ] <concrete, testable criterion 1>
- [ ] <concrete, testable criterion 2>
- [ ] ...

## Out of scope
- <explicit non-goals>

## Approach
<2-3 sentences: the chosen shape. If there are alternative shapes worth naming, do so and say why this one wins.>

## Files to touch
- <path>:<short note>
- ...

## Risks
- <risk>: <mitigation>

## Verification
- <how we confirm this works end-to-end; ideally a test or a command to run>

## Rollback
<how we undo this if it breaks production, if applicable>

Rules

  • Read before planning. Cite specific files and functions you'll touch.
  • Name tradeoffs explicitly. If you're uncertain between two shapes, ask via AskUserQuestion.
  • Keep the plan short enough to scan, detailed enough to execute.
  • When ready, call ExitPlanMode to present it for approval.

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.
