DHDNA Profiler — Cognitive Pattern Extraction

A structured system for extracting the cognitive fingerprint of any text's author. Based on the Digital Human DNA (DHDNA) framework — the theory that every mind has a unique signature pattern expressed through how it reasons, decides, values, and communicates.

Published research: DHDNA Pre-print (DOI: 10.5281/zenodo.18736629) | IDNA Consolidation v2 (DOI: 10.5281/zenodo.18807387)

Core Concept

Just as biological DNA encodes physical identity through base pairs, Digital Human DNA encodes cognitive identity through thinking patterns. Every person's combination of analytical depth, creative range, emotional processing, strategic thinking, and ethical reasoning creates a unique cognitive signature — as distinctive as a fingerprint.

The profiler doesn't judge thinking as "good" or "bad." It maps the topology of how a mind works.

The 12 Cognitive Dimensions

When profiling text, score each dimension on a 1–10 scale based on evidence in the text:

The 6 Tension Pairs

Dimensions exist in tension — high scores on one often correlate with lower scores on its pair. These tensions ARE the cognitive signature:

How to Profile

Phase 1 — Evidence Collection

Read the text carefully. For each dimension, identify specific textual evidence:

Direct quotes that demonstrate the dimension
Structural patterns (how arguments are built)
What's present AND what's absent (gaps reveal as much as content)
Recurring patterns across multiple passages

Phase 2 — Scoring

For each of the 12 dimensions:

Score 1-10 based on evidence
Cite the strongest textual evidence for that score
Flag confidence level: HIGH (multiple clear signals), MEDIUM (some signals), LOW (inferred)

Phase 3 — Pattern Synthesis

After scoring, identify:

Dominant Pattern: The 2-3 highest-scoring dimensions — this is the mind's "home base"

Shadow Pattern: The 2-3 lowest-scoring dimensions — this is where the mind doesn't naturally go

Signature Tensions: Which tension pairs show the widest gap? These define the cognitive style more than any individual score.

Reasoning Topology: How does the mind move through ideas?

Linear (A → B → C → conclusion)
Spiral (approaches the same idea from multiple angles, each time deeper)
Web (connects disparate domains into synthesis)
Dialectic (thesis → antithesis → synthesis)
Fractal (same pattern at micro and macro levels)

Decision Fingerprint: When facing choices, does this mind:

Analyze first, then decide? (Analytical-dominant)
Feel first, then rationalize? (Emotional-dominant)
Envision the outcome first, then work backward? (Strategic-dominant)
Question the question itself? (Metacognitive-dominant)

Phase 4 — Profile Output

Present the profile as:

═══════════════════════════════════════════

Comparison Mode

When the user provides two or more texts from different authors, produce individual profiles and then a comparison synthesis:

Where do the minds converge? (shared high dimensions)
Where do they diverge? (opposing scores on the same dimension)
Which tension pairs would create productive disagreement?
If these minds were in a room together, what would the conversation look like?

Self-Profile Mode

If the user asks to profile their own thinking (using the conversation history as text), be transparent:

material and wait for an answer. Prior turns were written for a different purpose, and mining them for psychological inference is not something to do silently.

Ask before reading back through the conversation. Say what you intend to use as source

Score based on the conversation so far
Acknowledge that conversational text may not represent the full range
Note that people often think differently when writing for an AI vs. writing for humans
Offer to re-profile if the user provides other writing samples

Consent and Scope

This skill infers personal cognitive and psychological attributes. That is a different thing from summarizing a document, and the boundaries matter:

material about the same author — other files, earlier sessions, or anything you happened to read.

Profile the text the user brings you for the current request. Do not go looking for more

not in the conversation and has not agreed to be analyzed — a colleague from a forwarded email, a candidate from an application, an author from a paper — label the output as an inference from one text sample, not a finding about that person.

A profile of a third party is speculative and must say so. When the author is someone who is

admission, clinical, disciplinary, or credit decisions are out of bounds; this framework has no validation supporting that use, and a 1–10 cognitive score reads as far more authoritative than it is.

Decline profiling that feeds a consequential decision about someone. Hiring, promotion,

for and are not sent to any service.

Everything stays local to the session. Profiles are not written anywhere the user did not ask

What This Is NOT

Not a personality test (MBTI, Big Five, etc.) — those measure behavioral tendencies, DHDNA measures cognitive architecture
Not a judgment of intelligence — a chess grandmaster and a poet may score very differently but both demonstrate profound cognitive capability
Not static — a person's DHDNA evolves as they learn, experience, and grow. A profile is a snapshot, not a destiny.

Use for HPLC, LC-MS/MS, GC, CE, ICP-MS, dissolution, qNMR, qPCR, NIR, and ligand binding or cell-based assays whenever the question is whether a procedure is fit for its intended purpose. Triggers include "method validation", "analytical method validation", "AMV", "validation protocol", "acceptance criteria", "linearity", "reportable range", "accuracy and precision", "repeatability", "intermediate precision", "recovery", "LOD", "LOQ", "detection limit", "quantitation limit", "specificity", "robustness", "method transfer", "method comparison", "Deming", "Passing-Bablok", "Bland-Altman", "equivalence testing", "OOS investigation", "ICH Q2", "Q2(R2)", "Q14", "USP 1225", "ICH M10", "incurred sample reanalysis", "ISR", "CLSI EP", and any request to show that an assay works.
AanndataData structure for annotated matrices in single-cell analysis. Use when working with .h5ad files or integrating with the scverse ecosystem. This is the data format skill—for analysis workflows use scanpy; for probabilistic models use scvi-tools; for population-scale queries use cellxgene-census.
AarborAutonomously improve a real artifact (code, training recipe, agent harness, data pipeline, prompt) against an objective and an evaluator, using Hypothesis Tree Refinement (HTR) from the Arbor paper. Use this whenever someone wants to iteratively optimize something over many experiments without overfitting — e.g. "get my model's eval score up", "improve this agent/harness", "tune this pipeline", "beat the baseline on this benchmark", "run a search over approaches and keep the best", "do an MLE-bench / Kaggle-style optimization", or any long-horizon "make this artifact better and don't just memorize the dev set" task. Trigger it even when the user doesn't say "Arbor" or "hypothesis tree" but describes repeated experiment-and-evaluate loops, branching exploration of competing ideas, or worries about a dev/test gap. Runs Claude itself as the coordinator with subagent executors in isolated git worktrees; for the standalone `arbor` CLI tool see references/arbor-upstream.md.
AarboretoInfer gene regulatory networks (GRNs) from gene expression data using scalable algorithms (GRNBoost2, GENIE3). Use when analyzing transcriptomics data (bulk RNA-seq, single-cell RNA-seq) to identify transcription factor-target gene relationships and regulatory interactions. Supports distributed computation for large-scale datasets.
AastropyCore Python library for astronomy and astrophysics workflows that need Astropy APIs, including units/quantities, coordinates, FITS I/O, tables, time systems, WCS, and cosmology. Use when implementing or debugging astronomical data analysis code with Astropy.
AautoskillObserve the user's screen via screenpipe, detect repeated research workflows, match them against existing scientific-agent-skills, and draft new skills (or composition recipes that chain existing ones) for the patterns not yet covered. Use when the user asks to analyze their recent work and propose skills based on what they actually do. Requires the screenpipe daemon (https://github.com/screenpipe/screenpipe) running locally on port 3030 — the skill has no other data source and will refuse to run if screenpipe is unreachable. All detection runs locally; only redacted cluster summaries reach the LLM.
