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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00047 | $0.00954 |
| Opus 5 | $0.00023 | $0.00477 |
| Sonnet 5 | $0.00009 | $0.00191 |
| Haiku 4.5 | $0.00005 | $0.00095 |
Grade A, and why
knowledge-catalog-discovery 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 3d 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 — 94 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Usage
All scripts can be executed using Node.js. Replace <param_name> and <param_value> with actual values.
Bash:
node <skill_dir>/scripts/<script_name>.js '{"<param_name>": "<param_value>"}'
PowerShell:
node <skill_dir>/scripts/<script_name>.js '{\"<param_name>\": \"<param_value>\"}'
Note: The scripts automatically load the environment variables from various .env files. Do not ask the user to set vars unless skill executions fails due to env var absence.
Scripts
lookup_context
Retrieves rich metadata regarding one or more data assets along with their relationships.
Parameters
| Name | Type | Description | Required | Default |
|---|---|---|---|---|
| resources | array | Required. A list of up to 10 resource names. Resources may belong to different projects, but all must belong to the same location. | Yes |
lookup_entry
Retrieves a specific metadata regarding a data asset (e.g. table/dataset/view) from Catalog
Parameters
| Name | Type | Description | Required | Default |
|---|---|---|---|---|
| entry | string | Required. The resource name of the Entry in the following form: projects/{project}/locations/{location}/entryGroups/{entryGroup}/entries/{entry}. | Yes | |
| view | integer |
## Argument: view
**Type:** Integer
**Description:** Optional. Specifies the parts of the entry and its aspects to return.
**Possible Values:**
* 1 (BASIC): Returns entry without aspects.
* 2 (FULL): Return all required aspects and the keys of non-required aspects. (Default)
* 3 (CUSTOM): Return the entry and aspects requested in aspect_types field (at most 100 aspects). Always use this view when aspect_types is not empty.
* 4 (ALL): Return the entry and both required and optional aspects (at most 100 aspects)
| No | `2` |
| aspectTypes | array | Optional. Limits the aspects returned to the provided aspect types. It only works when used together with CUSTOM view. | No | [] |
What ships with it
4 files 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.
