CRUX-Compress: Skill for Cursor

.cursor/skills/crux-skill-memory-meditation-research/SKILL.md

crux-skill-memory-meditation-research is a skill for Cursor from zotoio/CRUX-Compress. It costs 0 tokens per session (12,895 once invoked), scanned A, original, MIT.

A research procedure for CRUX memory meditation, which explores stored memories in depth before consolidating them. It coordinates recursive research, citations, reviews, additional focus areas, and final report preparation.

In plain words
What is it for?
Use it for full research-mode meditation runs and for agents working on their research branches or peer reviews. It is not for quick runs, ensemble aggregation, or final review tasks.
Why use it?
It keeps a complex memory review thorough and organized across several levels of investigation. It also ensures that the requested focus areas, citations, peer review, and report requirements are handled in the right sequence.

Skill for Cursor

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

crux-skill-memory-meditation-research 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 2mo 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.

CRUX Skill: Memory Meditation — Research Protocol

Implements the full Research-mode meditation contract: Phases A–G recursive depth-first exploration, depth-0 manager steps 1–13 (including step 4b 4-mode additional_focus_areas[] reconciliation, step 8 K10c in-pass reflection, and step 8b respawn-payload prep), facet registry lock, citations index, peer review file spec, and comprehensiveness honouring at leaf depth.

When to Use

Load this skill when:

  • The crux-cursor-meditation-guide agent is spawned in Research mode (no --quick flag, meditateMode: "research")
  • You are executing the depth-0 manager workflow (steps 1–13)
  • You are executing as a child Research-mode agent at depth 1, 2, or 3 (Phases A–G)
  • You are executing as a peer-review agent (peerReviewForBranch set)

Never load this skill in Quick mode, Ensemble Aggregation mode, or Adversarial Review function — those are owned by meditation-quick, meditation-ensemble, and meditation-review respectively.

Prerequisites

  1. Verify flags.enableMemories is "true" (abort if not)
  2. Confirm comprehensiveness: payload is present in the spawn prompt — abort with: "comprehensiveness: payload required; missing from spawn prompt — caller misconfigured" if missing
  3. Confirm theming: payload is present — abort with a clear error pointing at Theme Preflight if missing
  4. Confirm modelStrategy: payload is present — abort with: "modelStrategy: payload required; missing from spawn prompt — caller misconfigured" if missing

Input Parameters (depth-0 manager invocation)

The depth-0 manager receives these parameters from the calling agent:

meditateMode: "research"
workingDir: "<absolute path to meditations/{yyyymmdd}-{topic-slug}/>"
theming: { ... }                  # Theme Preflight payload — REQUIRED
comprehensiveness: { ... }        # Richness payload — REQUIRED; abort if missing
modelStrategy: { ... }            # Model strategy payload — REQUIRED; abort if missing
confirmDeepFacets: "none" | "depth_2_only" | "all_levels"
maxDepth: 1 | 2 | 3               # default 3
ensembleModel: "<model-slug>"     # derived from modelStrategy at the depth-0 manager; carrier for per-spawn model: selection
preConfirmedFacets: [ ... ]       # only when in ensemble_max — skip step 4 derivation

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.
