hyper-plan

A planning skill that breaks a large software task into small, ordered work items and saves the plan in the project. For very large tasks, it first creates a roadmap and then expands one milestone into detailed tasks.

In plain words
What is it for?
Use it before starting a non-trivial implementation or when invoking the hyper-plan command to create an actionable plan.
Why use it?
It gives complex implementation work a clear sequence before coding begins and connects research, planning, review, and implementation documents.

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

hyper-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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 163 lines — stays where its author put it; the contents beside it link to each section on GitHub.

hyper-plan

Plan generation gate. Dispatches the planner agent to produce a multi-task plan; saves it to .hyperclaude/plans/<YYYYMMDD-HHMM>-<slug>.md. When a recent hyper-research artifact matches, the plan inherits its slug so research → plan → plan-review form a linked trio.

For an oversized task the planner returns an epic roadmap (tier: epic, saved under .hyperclaude/epics/) — a list of ## Milestone N: chunks — instead of one giant detailed plan; the skill then auto-expands Milestone 1 into a runnable detailed plan under .hyperclaude/plans/. Later milestones expand on demand via /hyperclaude:hyper-plan milestone <K>epic-aware: it reads the roadmap and carries that milestone's Depends on: context into the expansion. This keeps each plan — and each hyper-plan-review — small. Vocabulary: epic → milestone → task (the roadmap is the epic, its chunks are milestones, each milestone expands into a detailed plan of tasks).

When to use

  • User typed /hyperclaude:hyper-plan <task>.
  • About to start multi-task work; want a plan /hyperclaude:hyper-plan-review can critique and /hyperclaude:hyper-implement can execute.
  • Expanding the next milestone of an existing epic roadmap: /hyperclaude:hyper-plan milestone <K> (see Milestone expansion).

Skip when:

  • The task is one step — dispatch the implementer agent directly (pass run_in_background: false for the result inline).
  • A recent plan already covers this task.

How to invoke

--resume is not supported (re-plan by running again with a refined task).

Invocation argument: $ARGUMENTS

Step 1 — Resolve mode, task + slug

First, check for milestone-expansion intent. If $ARGUMENTS matches [<epic-roadmap-path>] milestone <K> — the word milestone followed by an integer, optionally preceded by a path to an epic roadmap, with nothing trailing (e.g. milestone 2) — this is a milestone expansion request: follow the Milestone expansion section below and skip the rest of Steps 1–5. (Trailing free text like milestone 2 of the rocket is NOT a match — treat it as a normal task.)

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.

hyper-plan is a skill published in the GitHub repository zeikar/hyperclaude (3 stars, last pushed 14d ago), licensed MIT. It adds 70 tokens to every session and 3,417 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
