Postgres
timescale/pg-aiguide
A skill your agent uses for any PostgreSQL database work — table design, indexing, data types, constraints, extensions (pgvector, PostGIS, TimescaleDB), search, and migrations.
Administrative operations on the Knowledge base: connect new pgvector servers, check health, view stats, export data, install parser models.

Administrative operations on the Knowledge base: connect new pgvector servers, check health, view stats, export data, install parser models.
- Works in 5 steps: If args missing, ask interactively (chat) → POST /api/knowledge/connections —… → POST… → …

What it does
Knowledge Admin is an agent skill from evolution-foundation/evo-nexus. 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').
Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Databases, covering Knowledge bases. It works with pgvector. The repository describes itself as: The open source operating system for AI-powered businesses.
When your agent uses it
- 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
Example prompts
- “connect a new pgvector”
- “status of connections”
- “how many docs do we have”
- “/knowledge-admin”
Requirements
- Python 3
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- If args missing, ask interactively (chat)
- POST /api/knowledge/connections — register (encryption via workspace key)
- POST /api/knowledge/connections/:id/configure — runs
- Show phase-by-phase progress
- Output: final status + next steps ("create your first space via UI or knowledge-organize action=create")
What it can do on your machine
Read from SKILL.md and the folder at commit 7f5dd76. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are python).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Knowledge Admin loads about 1k tokens when it runs. Until then it costs about 87 tokens; SKILL.md has 215 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 215 words (~1,045 tokens).
“Group: Administration. Consolidates connect/health/stats/export/install-parser via subcommand.”
