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 | $0.00040 | $0.00818 |
| Opus 5 | $0.00020 | $0.00409 |
| Sonnet 5 | $0.00008 | $0.00164 |
| Haiku 4.5 | $0.00004 | $0.00082 |
Grade A, and why
alloydb-postgres-replication 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 11d 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.
This is a copy
97% identical to alloydb-postgres-replication — 8 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 99 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
database_overview
Fetches the current state of the PostgreSQL server, returning the version, whether it's a replica, uptime duration, maximum connection limit, number of current connections, number of active connections, and the percentage of connections in use.
get_instance
Retrieves details about a specific AlloyDB instance.
Parameters
| Name | Type | Description | Required | Default |
|---|---|---|---|---|
| project | string | The GCP project ID. This is pre-configured; do not ask for it unless the user explicitly provides a different one. | No | |
| location | string | The location of the instance (e.g., 'us-central1'). | Yes | |
| cluster | string | The ID of the cluster. | Yes | |
| instance | string | The ID of the instance. | Yes |
list_instances
Lists all AlloyDB instances in a given project, location and cluster.
Parameters
| Name | Type | Description | Required | Default |
|---|---|---|---|---|
| project | string | The GCP project ID. This is pre-configured; do not ask for it unless the user explicitly provides a different one. | No | |
| location | string | Optional: The location of the cluster (e.g., 'us-central1'). Use '-' to get results for all regions.(Default: '-') | No | - |
| cluster | string | Optional: The ID of the cluster to list instances from. Use '-' to get results for all clusters.(Default: '-') | No | - |
list_publication_tables
Parameters
| Name | Type | Description | Required | Default |
|---|---|---|---|---|
| table_names | string | Optional: Filters by a comma-separated list of table names. | No | `` |
| publication_names | string | Optional: Filters by a comma-separated list of publication names. | No | `` |
| schema_names | string | Optional: Filters by a comma-separated list of schema names. | No | `` |
| limit | integer | Optional: The maximum number of rows to return. | No | 50 |
What ships with it
6 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.
