hyperplan

hyperplan is a skill for Claude Code, Codex from Master0fFate/parallax-claudecode. It costs 22 tokens per session (237 once invoked), scanned A, original, MIT.

A skill that improves a non-trivial implementation plan through three rounds of criticism and evidence-based synthesis. The critics examine practical delivery, integration tests, security, architecture, and human impact.

In plain words
What is it for?
Use it to challenge and refine plans for complex engineering work, then capture surviving constraints, decisions, risks, and open questions.
Why use it?
It exposes risks and weak assumptions before work begins, especially for integration, security, migration, architecture, or operational changes.

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

hyperplan 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

Hyperplan

Use parallax_hyperplan on $ARGUMENTS when integration, security, migration, architecture, or operational risk justifies the cost. Let trivial plans skip unless the user requests force.

  1. Generate the analysis round. Dispatch returned prompts independently so critics do not anchor on one another.
  2. Collect structured findings from the selected Pragmatist, Integration Tester, Sentinel, Architectural Strategist, and Humanist angles.
  3. Generate cross-attacks using all round-one findings. Require DEFEND, REFINE, or CONCEDE outcomes backed by evidence.
  4. Generate defenses from the attack map. A defense must cite a constraint or observation; rhetoric is not evidence.
  5. Synthesize all critiques. Apply surviving hard constraints, decisions, risks, and open questions to the plan.

Do not paste hostile-agent prose into the final plan. Deduplicate findings, reject unsupported claims, preserve provenance for material risks, and state what changed.

Changes

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.
