dream

dream is a skill for Claude Code, Codex from ariaxhan/kernel-claude. It costs 39 tokens per session (1,704 once invoked), scanned A, original, MIT.

A structured idea-exploration skill that compares several viewpoints, challenges each proposal, and scores the results. It uses project files and prior recorded learnings when shaping an approach.

In plain words
What is it for?
Use it before significant design or implementation decisions to compare a minimal change, a complete architecture, and a smaller first version with an upgrade path.
Why use it?
It reduces the risk of choosing an attractive idea that does not fit the codebase, constraints, or security needs.

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

dream 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 — 196 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Not "give me 3 options" — structured divergence: competing value systems + adversarial stress test + integrity scoring.

The winning approach is the one that SURVIVES attack, not the one that sounds best.

Use before any non-trivial decision. Use when the obvious answer feels too easy.

Dreams that ignore the codebase are fantasies, not proposals.

Target: 90% code reduction. Must reference actual files that could be deleted.
Format: 3-8 lines. Effort estimate. Coverage percentage.
Target: complete solution. Must sketch actual architecture, not hand-wave.
Format: full description with component diagram. Effort estimate.
Target: 80% solution with clear upgrade path.
Must explicitly state what's deferred and the cost of deferral.
Format: concrete plan. Effort estimate. Tradeoff table.

Tier 1: generate all 3 inline. Tier 2+: spawn dreamer agent for codebase-grounded perspectives.

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.

dream is a skill published in the GitHub repository ariaxhan/kernel-claude (12 stars, last pushed today), licensed MIT. It adds 39 tokens to every session and 1,704 once invoked, about $0.0002 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 2026-08-30.
