context

A workflow for extracting governed metadata from Collibra, a system for managing an organization’s data knowledge graph.

In plain words
What is it for?
Use it to discover, inspect, and run Context Specifications—blueprints that select related assets and fields and return them in a defined shape.
Why use it?
It helps retrieve only the metadata needed for a target system instead of handling the entire knowledge graph.

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

context 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.

Context generation: extract shaped metadata for any target system

A Context Specification is a blueprint that defines a governed subset of Collibra's Knowledge Graph. Starting from an asset (e.g., a Table), it specifies which relations to traverse, what fields to pull, and what shape to return for any target system: Snowflake, Databricks, a data product UI, or an AI agent's reasoning process.

In other words: Context Specifications define which slice of the Knowledge Graph matters for a specific use case, and what shape that slice should take when delivered to downstream consumers.

This skill explains the three-tool workflow: discover which specs are available, inspect a spec if needed, and execute it to get the shaped output.


The three tools

Tool Purpose Returns When required
list_context_specifications Discover which Context Specifications (Knowledge Graph blueprints) are available for an asset or asset type List of spec names, descriptions, and IDs Always, entry point
get_context_specification Inspect a spec's blueprint: which relations it defines, what fields it extracts from the Knowledge Graph, what transforms it applies Complete YAML mapping and spec metadata Optional, only when user asks what a spec covers
get_asset_details (with contextSpecificationId) Execute a spec's blueprint against an asset to extract and shape its governed metadata subset; returns full asset details alongside the generated context Asset details + structured YAML context shaped for the target system Always, output step

Decision rule: which tool to call first

Always start with list_context_specifications. It takes one of two parameters:

Option A: You have an asset UUID

Call list_context_specifications(assetId=<UUID>) to find specs whose source asset type matches that asset's type.

Use when: You've already resolved a user's request to a specific Collibra asset (e.g., "the Orders table" → resolved to UUID abc-123).

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.

context is a skill published in the GitHub repository collibra/chip (36 stars, last pushed 4d ago), licensed Apache-2.0. It adds 53 tokens to every session and 2,786 once invoked, about $0.0003 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.
