Build a prioritised memory index from all memory files and reference trackers. Use when rebuilding the memory index, after memory CRUD operations, or when agents need a sorted discovery list.
Consolidate, promote, demote, and archive memories based on strength, usage patterns, and type transition rules. Use when running REM sleep, rebalancing memory strength, detecting conflicts, or cleaning up orphaned trackers.
File-based coordination primitives for meditation: artefact filename grammar (18 rows including `init-suggestions-{ts}.yml`, `finalisation-enhancements.yml`, per-tree ensemble variants, and 4 follow-up artefact types), placeholders, prefix-glob polling rule, never-hard-code invariant, retrospective template, Branch & Leaf Index template (single-model + ensemble variants). Use whenever the `crux-cursor-meditation-guide` agent reads, writes, or links a working-directory artefact.
Ensemble Aggregation function for meditation: reads N model consolidations, writes `cross-model-synthesis.md`, performs K10 root cross-model reflection (step 3c), manages K10 layered cadence steps 3b–3f (per-tree `finalisation-enhancements.yml` reads + root combined YAML write with `cross_model_candidates` + `union_candidates`), returns single combined `needs_user_input`, dispatches resume-handler by `source` provenance, and hands off to the report skill for ensemble HTML+PDF generation. Use when the `crux-cursor-meditation-guide` agent is spawned with `ensembleAggregation: true`.
Quick-mode meditation protocol: 6-step parallel fan-out with optional deep-confirm hook, warn-only citation validation, upfront child derivation, no peer review, K10c reflection (same rubric, warn-only at every richness level per K7). Use when the `crux-cursor-meditation-guide` agent runs the Quick depth-0 manager or any Quick-mode child agent.
Mandatory paired HTML+PDF report generation for meditation: Comprehensiveness Level Mapping (12 dimensions × 4 levels), anti-homogenisation rules, Universal Contrast, light/dark mode + print TOC, Chart.js / D3 / calculator content minima with static fallbacks, Per-Branch Section Rule, Depth-3 Leaf Inclusion Rule, Peer-Review Surfacing Rule, Init-Suggestions Honour rules, K10b Per-Cheap-Type Rendering Contract (7 cheap types), and Report-Skill Respawn Protocol resume-handler. Use when the `crux-cursor-meditation-guide` agent runs report generation (step 12), when the ensemble aggregator generates the ensemble-level report, or when the report skill is respawned via Dim 13.

Multi-purpose utility for CRUX compression workflows. Provides deterministic tools for token estimation and checksum calculation.
# Token count estimation
python3 .cursor/skills/crux/crux-utils/scripts/crux-utils.py --token-count <file>
# Compare source vs CRUX (ratio mode, default target 25%)
python3 .cursor/skills/crux/crux-utils/scripts/crux-utils.py --token-count --ratio <source> <crux>
# Compare with custom target (e.g. 40%)
python3 .cursor/skills/crux/crux-utils/scripts/crux-utils.py --token-count --ratio <source> <crux> --target 40
# Get checksum for sourceChecksum frontmatter
python3 .cursor/skills/crux/crux-utils/scripts/crux-utils.py --cksum <file>
--token-count <file>Estimate token count for a single file.
Output:
=== Token Estimate: example.md ===
Prose tokens: 397
Code tokens: 0
Special tokens: 0
---
TOTAL TOKENS: 397
--token-count --ratio <source> <crux> [--target <n>]Compare source file vs CRUX file and calculate compression ratio.
The --target option sets the compression target percentage (1-100). Defaults to 25 if omitted, matching the CRUX spec's recommended target for text/code content.
Output:

Source tokens: 397
CRUX tokens: 140
