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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00233 | $0.04367 |
| Opus 5.5 | $0.00093 | $0.01747 |
| Sonnet 5.5 | $0.00047 | $0.00873 |
| Haiku 4.5 | $0.00023 | $0.00437 |
Grade A, and why
fabric-variable-library 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 14d 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.
How it starts
The opening of the file, as written. The whole thing — 341 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Fabric Variable Library
Config-as-code for parameterizing notebooks and pipelines per environment. Stored as a Fabric item with definition parts under source control; consumed at runtime via notebookutils.variableLibrary (notebooks) or the libraryVariables block (pipelines).
Definition parts
| Part Path | Content | Required |
|---|---|---|
variables.json |
Variable names, types, default values | Yes |
settings.json |
valueSetsOrder (empty array when no Value Sets) |
Yes |
valueSets/<name>.json |
Per-environment overrides | Only when using Value Sets |
.platform |
Item metadata JSON | No (handled by Git/REST layer) |
VariableLibrary does not support the format field in definition requests: omit the key entirely, since even "format": null may cause errors. (See fabric-rest-api skill for the definition envelope.)
Supported variable types
| Type | Tier | Description |
|---|---|---|
String |
Basic | Text |
Boolean |
Basic | JSON true / false, never quoted |
Number |
Basic | Floating-point. Not supported in pipelines |
Integer |
Basic | Whole numbers |
DateTime |
Basic | ISO 8601 |
Guid |
Basic | GUID |
ItemReference |
Advanced | Fabric item binding ({itemId, workspaceId}) |
ConnectionReference |
Advanced | External connection (Snowflake, Azure SQL, …) by ID, so items reference it without embedded credentials; exposes .connectionId |
variables.json
{
"$schema": "https://developer.microsoft.com/json-schemas/fabric/item/variableLibrary/definition/variables/1.0.0/schema.json",
"variables": [
{ "name": "lakehouse_name", "type": "String", "value": "bronze_lakehouse" },
{ "name": "enable_logging", "type": "Boolean", "value": true },
{ "name": "target_warehouse", "type": "ItemReference",
"value": { "itemId": "...", "workspaceId": "..." } }
]
}
A Boolean's value is a bare JSON true or false: Learn's definition
article types value as JSON, and an update from Git took a bare one
and getDefinition returned it bare (a client estate, 2026-10-13).
Whether a sync rejects a quoted "true" or coerces it is unverified.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

fabric-variable-library is a skill published in the GitHub repository wardawgmalvicious/agent-config (1 stars, last pushed 10d ago), licensed MIT. It adds 233 tokens to every session and 4,367 once invoked, about $0.0009 per session on Opus 5.5. 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 2026-08-31.
