What it does

Oracle Data Guard is an agent skill from oracle/skills, published by the product's own GitHub organization. Provide operational guidance for Oracle Data Guard and SQLcl DG. Use when a user asks about SQLcl DG commands, Data Guard Broker fixed views, FSFO or observer state, transport or apply lag, ASYNC/SYNC/FASTSYNC performance, redo apply tuning, SIRA/MIRA, or runnable Data Guard diagnostic SQL.

Its SKILL.md is about 650 tokens, which your agent loads only when the skill is triggered. The skill folder holds 14 other files, including reference files (for example `agents/openai.yaml`, `references/00_DG_RESOURCE_INDEX.md` and `references/01_SQLCL_DG_COMMANDS.md`).

It sits in Databases, covering SQL. It works with SQL. The repository describes itself as: Oracle Skills is a curated, open-source collection of practical, installable skills for working with Oracle technologies. It provides developers, administrators, and AI agents…

When your agent uses it

A user asks about SQLcl DG commands
Data Guard Broker fixed views
ASYNC/SYNC/FASTSYNC performance
Redo apply tuning

Example prompts

“/oracle-data-guard”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

Identify the topology and concern: Broker versus SQLcl, transport versus apply, and ASYNC versus SYNC/FASTSYNC where relevant.
Read the selected reference. Read 09_SQL_QUERY_COOKBOOK.md only when executable SQL directly helps.
State the evidence needed, provide safe diagnostic steps, and distinguish facts from hypotheses.
Treat example timestamps as placeholders; ask for the actual incident window when it affects a query.
When both transport and apply lag are zero, frame guidance as a health check, baseline, configuration review, or commit-latency…

What it can do on your machine

Read from SKILL.md and the folder at commit 6c57a52. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Oracle Data Guard loads about 646 tokens when it runs, and up to ~12k if it reads all its reference files. Until then it costs about 77 tokens; SKILL.md has 249 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~77
When it runs · the whole SKILL.md, loaded when a task matches: ~646
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~12k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (UPL-1.0) doesn't allow us to republish the file, so here is its outline and opening line. It has 249 words (~646 tokens).

“Use the bundled references as the source of truth for SQLcl MCP Data Guard guidance. Read only the smallest relevant reference. Do not claim to have inspected a live database, Broker configuration, or observer unless the user provides output or…”
