fetch

A command for retrieving objects from Weaviate collections by their ID or by filters such as property values, comparisons, and combined AND/OR conditions.

In plain words
What is it for?
Use it to fetch an object by UUID or find matching objects with simple or nested filter rules.
Why use it?
It avoids writing separate database queries when you need a specific record or a filtered set of records.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

fetch scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Fetch and Filter Objects

Fetch specific objects by ID or filter them using complex logic (AND/OR). Always use this command after exploring the collection using /weaviate:explore command.

Usage

/weaviate:fetch collection "CollectionName" filters '{"property": "prop", "operator": "equal", "value": "val"}'
/weaviate:fetch collection "CollectionName" id "UUID"

Workflow

  1. Fetch by ID:

    uv run ${CLAUDE_PLUGIN_ROOT}/skills/weaviate/scripts/fetch_filter.py "COLLECTION_NAME" --id "UUID"
    
  2. Fetch with Filters:

    uv run ${CLAUDE_PLUGIN_ROOT}/skills/weaviate/scripts/fetch_filter.py "COLLECTION_NAME" --filters 'JSON_STRING' --limit 10
    

Filter Syntax

Filters must be a JSON string.

Simple Filter:

[{"property": "category", "operator": "equal", "value": "Science"}]

OR Logic:

{
  "operator": "or",
  "filters": [
    {"property": "word_count", "operator": "greater_than", "value": 1000},
    {"property": "title", "operator": "like", "value": "*Research*"}
  ]
}

Complex Nesting:

{
  "operator": "and",
  "filters": [
    {"property": "is_published", "operator": "equal", "value": true},
    {
      "operator": "or", 
      "filters": [
        {"property": "author", "operator": "equal", "value": "Jane Doe"},
        {"property": "views", "operator": "greater_than", "value": 5000}
      ]
    }
  ]
}

Operators

  • equal, not_equal
  • less_than, less_or_equal
  • greater_than, greater_or_equal
  • like (use * for wildcards)
  • contains_any, contains_all (value must be a list)
  • is_none (value must be boolean)

Environment

Requires:

  • WEAVIATE_URL: Weaviate Cloud cluster URL
  • WEAVIATE_API_KEY: API key for authentication

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

fetch is a command published in the GitHub repository weaviate/agent-skills (103 stars, last pushed 2mo ago), licensed BSD-3-Clause. It adds 9 tokens to every session and 568 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
