What it does

Apex is an agent skill from oracle/skills, published by the product's own GitHub organization. Oracle APEX skills for Oracle APEX application development.

Example prompts

  • “/apex”

Workflow steps

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

  1. Start with the routing table below.
  2. For APEXlang work, open apex/apexlang/SKILL.md and route to the matching APEX version.
  3. Read only the specific file or category you need.

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

Apex loads about 379 tokens when it runs. Until then it costs about 16 tokens; SKILL.md has 78 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~16
When it runs · the whole SKILL.md, loaded when a task matches
~379

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 78 words (~379 tokens).

“This domain contains Oracle APEX skills for Oracle APEX application development.”
