hyper-setup

A prerequisite checker for the hyperclaude development workflow. It tests whether required programs and command-line options are installed and reports each check as structured data.

In plain words
What is it for?
Use it to check Node.js, Codex CLI, Git, the Codex search option, and Claude Code versions. It reports the status and severity of every prerequisite.
Why use it?
It finds missing or unsupported tools before the workflow fails later. The report also gives a suggested fix for each failed check.

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.

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-setup 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 yesterday.

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 — 57 lines — stays where its author put it; the contents beside it link to each section on GitHub.

hyper-setup

Run the doctor probe. Parse the JSON it emits and report per-check status plus the overall verdict.

Prerequisite probe: !node "${CLAUDE_PLUGIN_ROOT}/scripts/setup-doctor.mjs"

What it checks

The probe emits one JSON line: { ok, checks: [{name, detected, required, status, severity, remediation}] }.

The five checks:

  1. Node.js >= 18 — severity: hard. hyperclaude's bridge is stdlib Node; versions below 18 are unsupported.
  2. codex-cli >= 0.130.0 on PATH — severity: hard. Version-floor check only (no capability probe). The bridge spawns codex exec; the tool must be present and at a known-good version.
  3. git on PATH — severity: hard. The bridge reads git state for slug generation and diff targets.
  4. codex --search global flag (pre-subcommand) — severity: hard. The bridge passes --search as a global flag before the subcommand on every Codex spawn; codex-cli must accept codex --search exec --help (exit 0).
  5. Claude Code >= 2.1.232 — severity: conditional. 2.1.232 is the known-good floor for the background-agent transport hyper-plan-loop, hyper-implement-loop, hyper-docs-loop, and hyper-auto (which chains hyper-plan-loop → hyper-implement-loop) use to reach their agent. Surfaced, not gated: a below-floor or unknown version (claude off PATH, unparseable output) is a WARN that never flips the verdict and blocks nothing — the full research→plan→implement flow works regardless.

Reporting directive

The inline probe above runs automatically; parse the single JSON line it emitted to stdout (do not run it again).

Distinguish by shape before deciding how to report:

  • If the JSON has a checks[] array — render the per-check table and verdict. This includes the normal ok:false "prerequisites failing" case. Do NOT use the fallback for this shape.
  • ONLY if there is no parseable JSON at all, or the JSON has an error key (the {ok:false,error:...} probe-failure shape with no usable checks[]) — use the fallback sentence below; never the fallback for a normal ok:false result that has checks[].

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-setup is a skill published in the GitHub repository zeikar/hyperclaude (3 stars, last pushed 14d ago), licensed MIT. It adds 13 tokens to every session and 1,025 once invoked, about $0.0001 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.
