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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00113 | $0.01772 |
| Opus 5 | $0.00056 | $0.00886 |
| Sonnet 5 | $0.00023 | $0.00354 |
| Haiku 4.5 | $0.00011 | $0.00177 |
Grade A, and why
databricks-live-unity-catalog-grant-guard-at-azure 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 8d 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.

Databricks Live Unity Catalog Grant Guard at Azure
Purpose
Act as the live mutating guard for Unity Catalog privilege management on Azure Databricks. On receipt of explicit written human approval, execute exactly ONE GRANT <privilege> ON <securable_type> <securable> TO <principal> statement — or its exact inverse REVOKE — on a single Unity Catalog securable (schema, table, or volume), scoped to a single privilege and a single principal. Capture prior state before execution. Emit a signed attestation. Never mutate without approval. Never execute bulk, wildcard, ALL PRIVILEGES, ownership transfer, or admin-level grants.
When to use
- A single, specific Unity Catalog privilege must be granted or revoked on one securable, with a full audit trail
- A human operator has provided a written approval token naming the exact securable, privilege, principal, and blast radius
- A prior-state capture and named rollback plan are required before any mutation proceeds
- The operation must be idempotent and produce a signed attestation
Live-guard gate
This skill operates at mutating-runtime (Phase B). It is never auto-dispatched by a maestro. Before any mutation executes:
- Require explicit written human approval naming: exact securable, exact privilege, exact principal, blast radius.
- Run dry-run preflight: show current grants on the target securable + the single SQL statement to be executed.
- Confirm scope and environment with the approver.
- Capture prior grant state (record current grants on the target securable before execution).
- Execute the single statement.
- Emit signed output attestation (
signed_with: idempotency-key) referencing the approval token, idempotency key, statement executed, and prior state snapshot.
Strictly-scoped operation contract
- EXACTLY ONE
GRANTorREVOKEper invocation — one privilege, one securable, one principal. - Securable types: schema, table, or volume within Unity Catalog.
- Preferred principals: account groups. Service principals acceptable. Interactive users require additional justification.
- REVOKE is the inverse: REVOKE exactly mirrors the GRANT — same privilege, same securable, same principal. Prior state must be captured before REVOKE.
- Idempotent: if the grant already exists (for GRANT) or is already absent (for REVOKE), record and return without error.
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.

databricks-live-unity-catalog-grant-guard-at-azure is a skill published in the GitHub repository VincentChuWaiChow/vanguard-frontier-agentic (22 stars, last pushed yesterday), licensed Apache-2.0. It adds 113 tokens to every session and 1,772 once invoked, about $0.0006 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 2026-09-04.
