persona-knowledge

Persistent, incremental, searchable persona knowledge base — the data layer between raw sources and persona training.

Architecture: MemPalace (storage + search) + Knowledge Graph (relationships + timeline) + Karpathy LLM Wiki (knowledge accumulation)

Dependency chain: data sources → persona-knowledge → anyone-skill / persona-model-trainer

---

When to use this skill

Trigger phrases:

"create a dataset for this persona"

"add data to the dataset"

"import my Obsidian vault"

"import my Twitter archive"

"build a knowledge base for X"

"export training data"

"search the persona dataset"

Not suitable when:

User wants a quick one-shot distillation without persistent storage (use anyone-skill alone)

User only has < 50 messages of data (too little to warrant a dataset)

---

Phase 1: Init

Create a new persona dataset:

python scripts/init_knowledge.py --slug {slug} --name "Display Name"

This creates ~/.openpersona/knowledge/{slug}/ with:

~/.openpersona/knowledge/{slug}/
  dataset.json                 # metadata: slug, name, created_at, stats
  .mempalace/                  # MemPalace local data (per-dataset isolation via palace_path)
    palace/                    # MemPalace internal store (ChromaDB + KG)
  sources/                     # immutable source file backups
    .source-index.json         # per-file metadata: hash, import time, line count, PII flags
  wiki/                        # Karpathy wiki (LLM-maintained derived artifact)
    _schema.md                 # wiki maintenance rules
    identity.md
    voice.md
    values.md
    thinking.md
    relationships.md           # generated from Knowledge Graph
    timeline.md                # generated from Knowledge Graph
    _contradictions.md
    _changelog.md
    _evidence.md

MemPalace palace structure:

One Wing per persona (named by slug)

Halls mapped to 5 persona dimensions:

- hall_facts — Identity (background, career, education) - hall_events — Memory (key events, turning points) - hall_preferences — Personality (values, preferences, boundaries) - hall_discoveries — Procedure (mental models, decision heuristics) - hall_voice — Interaction (vocabulary, rhythm, humor, emotional temperature)

Gate: Confirm slug and display name with the user before proceeding.

---

Phase 2: Ingest

Import data sources into the dataset. Can be called multiple times for incremental ingestion.

python scripts/ingest.py --slug {slug} --source  [--adapter ] [--since ]

Three adapters cover all supported formats:

| Source | Adapter | Detection | |--------|---------|-----------| | Obsidian vault | universal | Directory containing .obsidian/ or *.md files | | GBrain export dir | universal | Markdown directory with .raw/ sidecar dirs | | .md / .txt / .csv / .pdf | universal | File extension | | .jsonl / .json | universal | File extension | | GBrain JSON export | universal | .json with memories key or --entity flag | | WhatsApp .txt export | chat_export | Matches WhatsApp timestamp pattern | | Telegram result.json | chat_export | JSON with chats key | | Signal export | chat_export | JSON with Signal message format | | iMessage .db | chat_export | SQLite with message + handle tables | | X (Twitter) archive | social | Directory containing data/tweets.js | | Instagram archive | social | Directory containing content/posts_1.json |

Ingest pipeline (per source):

1. Parse — adapter converts source to unified [{role, content, timestamp, source_file, source_type}] 2. PII scan — flag SSN, credit card, email, password patterns 3. Hash dedup — SHA-256 content hash, skip already-ingested entries 4. Write sources/ — save parsed data as JSONL backup (immutable, one file per source) 5. Store in MemPalace — verbatim text into ChromaDB via palace wing/hall structure 6. Extract KG triples — detect entities and relationships, write to Knowledge Graph with temporal validity 7. Report — print source name, message count, assistant turns, PII flags, new KG entities

After each source is ingested, report:

✅ whatsapp-2024.txt → 1,247 messages (892 assistant turns)
   PII: none detected
   KG: +3 entities, +7 relationships
   → sources/whatsapp-2024.jsonl

---

Phase 3: Wiki Build (agent task — not a script)

After ingesting new data, the agent reads MemPalace content and Knowledge Graph relationships, then builds or updates the wiki pages following the Karpathy LLM Wiki pattern.

> This phase is driven by agent intelligence (SKILL.md instructions), not by automated scripts. The LLM decides which pages to update, how to phrase entries, and how to tag evidence.

Ingest operation (after each Phase 2 run)

1. Read new data from MemPalace (search the wing for recently added entries) 2. For each relevant wiki page, check if the new data adds, contradicts, or refines existing content 3. Update 5-15 wiki pages with new information, using evidence tags: - [L1:source] — direct quote, traceable - [L2] — reported/paraphrased, verifiable - [L3:inferred] — reasonably inferred from multiple signals - [L4:inspired] — impression-based 4. Add backlinks between related pages using [[page]] wikilink syntax 5. Record contradictions in _contradictions.md with both sides cited 6. Append entry to _changelog.md 7. Update counts in _evidence.md

Query operation

When the user asks a question about the persona:

1. Search MemPalace semantically for relevant memories 2. Navigate wiki pages for structured knowledge 3. Synthesize an answer 4. If the query reveals new insights, write them back to the appropriate wiki page

Lint operation

Run periodically or before export:

python scripts/lint_wiki.py --slug {slug}

Checks:

Broken [[links]] (referenced page doesn't exist)

Empty pages (created but never populated)

Contradictions without resolution notes

Evidence coverage (pages with < 2 evidence tags)

Source coverage (MemPalace entries not reflected in any wiki page)

Wiki page structure (see references/wiki-schema.md for full spec)

Each page follows this template:

# {Page Title}
> One-sentence summary of this page's scope.
Content
{Structured content with [L?:source] evidence tags and [[backlinks]]}
Sources
{source_file}: {what was extracted} [L?]
See also
[[related_page]]

Knowledge Graph–driven pages

relationships.md and timeline.md are generated from the Knowledge Graph, not written freehand:

from mempalace.knowledge_graph import KnowledgeGraph
kg = KnowledgeGraph(palace_path)
kg.timeline(slug)           # → chronological event list for timeline.md
kg.query_entity(slug)       # → current relationships for relationships.md

After generating, the agent may annotate with evidence tags and additional context.

---

Phase 4: Export

Generate a training/ directory compatible with persona-model-trainer:

python scripts/export_training.py --slug {slug} --output training/

Each export is automatically versioned (v1, v2, …). Override with --version:

python scripts/export_training.py --slug {slug} --output training/ --version v3

List export history:

python scripts/export_training.py --slug {slug} --list
v1  2026-04-01 10:00  142 turns  sha256:a3f9c2d1  3 sources
v2  2026-04-10 14:22  198 turns  sha256:c7d2e1f3  4 sources

Output:

training/
  raw/                      # copied from sources/ (authentic voice, unmodified)
  conversations.jsonl       # generated from wiki pages (structured Q-A pairs)
  profile.md                # summarized from wiki identity/voice/values
  metadata.json             # slug, source count, turn count, export version + hash

How each file is built:

training/raw/ — direct copy of sources/*.jsonl and sources/*.txt files

training/conversations.jsonl — the agent reads wiki pages and generates distilled user/assistant turn pairs representing the persona's voice, knowledge, and values

training/profile.md — 300-500 word character sheet derived from identity.md, voice.md, values.md

training/metadata.json — slug, name, subject_type, created_at, source_count, total_words, distilled_turns, raw_files + versioning fields:

- export_version — version tag (e.g. "v2") - export_hash — SHA-256 of conversations.jsonl (e.g. "sha256:c7d2e1f3...") - source_snapshot — {filename: sha256_hash} dict of all source files at export time

Export history is appended to dataset.json → export_history[] after each run.

Downstream traceability: persona-model-trainer's pipeline.sh reads export_version and export_hash from metadata.json and injects them as dataset_version / dataset_export_hash into training_summary.json, forming a complete provenance chain from source data to trained model adapter.

This output is directly consumable by persona-model-trainer's prepare_data.py — no changes needed downstream.

→ Next step — train a local persona model:

bash skills/persona-model-trainer/scripts/pipeline.sh \
  --slug {slug} \
  --model google/gemma-4-E4B-it \
  --source ./training \
  --method mlx \       # or: unsloth (NVIDIA GPU) / colab (no GPU)
  --preset gemma4 \
  --probes ./training/probes.json

Phase 5: Search

Query the dataset using MemPalace's semantic search and Knowledge Graph:

# Semantic search across all stored memories
mempalace search "how does this person handle conflict" --wing {slug}
Knowledge Graph: look up an entity's relationships
python scripts/query_kg.py --slug {slug} --entity "Tom"
Knowledge Graph: shortest path between two entities
python scripts/query_kg.py --slug {slug} --path "Tom" "Alice"
Knowledge Graph: overall statistics
python scripts/query_kg.py --slug {slug} --stats
Knowledge Graph: JSON output (for programmatic use)
python scripts/query_kg.py --slug {slug} --entity "Tom" --json
Wake-up summary (~170 tokens)
mempalace wake-up --wing {slug}

The agent can also search programmatically during wiki build or distillation:

from mempalace.searcher import search_memories
results = search_memories("vocabulary patterns", palace_path="~/.openpersona/knowledge/{slug}/.mempalace/palace")

---

Phase 6: Maintain

Ongoing dataset management:

Add new source: run Phase 2 (Ingest) again with new files → triggers wiki update

Remove source: delete from sources/ + re-index → run wiki lint to flag orphaned content

Wiki lint: python scripts/lint_wiki.py --slug {slug} — health check

Dataset stats: python scripts/init_knowledge.py --slug {slug} --stats — show current stats

List datasets: ls ~/.openpersona/knowledge/ — all available datasets
