hyper-plan-review

hyper-plan-review is a skill for Claude Code, Codex from zeikar/hyperclaude. It costs 64 tokens per session (1,340 once invoked), scanned A, original, MIT.

A review step for checking an existing implementation plan before coding begins. It sends the plan to Codex for critique, saves the review, and uses that review to refine the plan.

In plain words
What is it for?
Use it to review a plan file in .hyperclaude/plans/ or resume an earlier plan review.
Why use it?
It can expose missing steps or questionable assumptions before they cause problems during implementation.

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.

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-review 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 4d 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 — 95 lines — stays where its author put it; the contents beside it link to each section on GitHub.

hyper-plan-review

Plan review gate. Locates a plan file, sends it to Codex for critique, saves the review to .hyperclaude/plan-reviews/<timestamp>-<slug>.md, and you read the review and refine the plan.

When to use

  • User typed /hyperclaude:hyper-plan-review (with or without an argument).
  • You just produced an implementation plan and want a critic pass before executing.

How to invoke

Invocation argument: $ARGUMENTS

--resume is supported. Paths with spaces are unsupported.

Argv grammar

Apply this regex to the trimmed $ARGUMENTS:

^(?:((?!--)\S+))?(?:\s*(--resume)(?:\s+(\S+))?)?\s*$
  • Group 1 = optional plan path (negative lookahead prevents matching --resume as a path)
  • Group 2 = literal "--resume" token (truthy when present, undefined when not)
  • Group 3 = optional resume artifact path

When Group 2 is '--resume' (truthy) and Group 3 is undefined, treat as --resume auto.

Valid invocations:

  • /hyperclaude:hyper-plan-review — auto-discovers most recent plan, fresh run
  • /hyperclaude:hyper-plan-review path/to/plan.md — explicit plan path, fresh run
  • /hyperclaude:hyper-plan-review --resume — auto-discovers plan, resumes from latest artifact (auto)
  • /hyperclaude:hyper-plan-review --resume <prev-artifact-path> — resumes from explicit artifact
  • /hyperclaude:hyper-plan-review path/to/plan.md --resume — explicit path, resume from auto
  • /hyperclaude:hyper-plan-review path/to/plan.md --resume <prev-artifact-path> — explicit path, explicit artifact

If the argument doesn't match the regex, ask the user to clarify and stop.

Resume semantics

See ${CLAUDE_PLUGIN_ROOT}/references/bridge-review-calls.md for the shared --resume semantics (explicit vs auto fallback, the template-version precondition). Plan-review's identity check keys on the plan path.

  • Budget exceeded (docs > 200KB after revision): bridge returns ok:false — NOT fallback. Tell user to narrow scope.

Step 1 — Resolve the plan path

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-review is a skill published in the GitHub repository zeikar/hyperclaude (3 stars, last pushed yesterday), licensed MIT. It adds 64 tokens to every session and 1,340 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.
