knowledge-admin

name	knowledge-admin
description	Administrative operations on the Knowledge base: connect new pgvector servers, check health, view stats, export data, install parser models. Use when the user wants to configure/monitor the system ('connect a new pgvector', 'status of connections', 'how many docs do we have', 'export backup of space X', 'install Marker models').

knowledge-admin

Group: Administration. Consolidates connect/health/stats/export/install-parser via subcommand.

When to trigger

• "Connect a new pgvector"
• "Status of connections"
• "How many docs are in Academy?"
• "Export space X as backup"
• "Install Marker models"

Arguments

Name	Type	Required	Description
action	str	yes	connect | health | stats | export | install-parser
(action-specific args)			see below

Actions

connect — New connection wizard

Optional args: slug, name, host, port, database, username, password, ssl_mode, connection_string.

Flow:

1. If args missing, ask interactively (chat):
   • Name ("What do you want to call this connection?")
   • Host, port (default 5432), user, password, database, SSL mode
   • OR paste a full connection string
2. POST /api/knowledge/connections — register (encryption via workspace key)
3. POST /api/knowledge/connections/:id/configure — runs:
   • SELECT version() (Postgres >= 14)
   • Validate pgvector >= 0.5
   • PgBouncer detect (port 6543, pooler, ?pgbouncer=true) → HTTP 422 with message
   • Alembic upgrade head
   • Seed knowledge_config
4. Show phase-by-phase progress
5. Output: final status + next steps ("create your first space via UI or knowledge-organize action=create")

health

from dashboard.backend.sdk_client import evo

conns = evo.get("/api/knowledge/connections")
for c in conns:
    health = evo.get(f"/api/knowledge/connections/{c['id']}/health")
    # aggregate: status, schema_version, pgvector_version, chunks, spaces, last_error

Output:

| Connection | Status | Schema | pgvector | Spaces | Chunks | Last health |
|---|---|---|---|---|---|---|
| academy | ✅ ready | v3 | 0.5.1 | 5 | 12,400 | 2026-04-20 14:05 |
| acme | ⚠️ needs_mig | v2 | 0.5.0 | 2 | 3,100 | 2026-04-20 14:05 |
| staging | ❌ error | — | — | — | — | `connection refused` |

stats

Aggregates per-connection + global stats:

stats = evo.get("/api/knowledge/stats")
# { connections: [...], total_documents: N, total_chunks: M, by_content_type: {...}, growth_7d: X }

Output:

## Knowledge stats

Total documents: {N}
Total chunks: {M}
Total spaces: {S}
Growth (last 7d): +{X} docs, +{Y} chunks

### By content_type
- lesson: {N}
- tutorial: {N}
- faq: {N}
...

### Per connection
| Connection | Docs | Chunks | Spaces |
...

export

Args: space_id (yes), format (default "jsonl"), connection.

docs = evo.get(
    "/api/knowledge/v1/documents",
    params={"space_id": space_id, "format": "jsonl", "include_chunks": True},
    headers={"X-Knowledge-Connection": connection},
)

# Save to workspace/data/knowledge-exports/{connection}_{space_slug}_{timestamp}.jsonl
from pathlib import Path
import json
from datetime import datetime

out = Path("workspace/data/knowledge-exports") / \
      f"{connection}_{space_id}_{datetime.now():%Y%m%d_%H%M%S}.jsonl"
out.parent.mkdir(parents=True, exist_ok=True)
with out.open("w") as f:
    for doc in docs:
        f.write(json.dumps(doc, ensure_ascii=False) + "\n")

print(f"Exported {len(docs)} docs to {out}")

install-parser

Downloads Marker models (Surya OCR ~500MB). Idempotent — uses sentinel file.

resp = evo.post("/api/knowledge/parsers/install", {})
# poll /api/knowledge/parsers/status until installed=true

Show progress. If already installed, no-op.

Actionable failures

• Invalid action → list actions
• Invalid credentials on connect → "Check host/port/user"
• PgBouncer detected → exact message from ADR-009
• Export without write permission → "Create workspace/data/knowledge-exports/ manually"
• Install-parser without disk → "No space. Marker needs ~500MB."
