What it does

Improve Oas is an agent skill from elastic/kibana, published by the product's own GitHub organization. Add or improve OpenAPI descriptions, examples, and code samples for a Kibana API area. Use when a plugin or package needs better OAS documentation — missing descriptions on schema fields, missing route summaries, missing examples, or missing code samples.

Its SKILL.md is about 4.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).

It sits in Backend & APIs, covering OpenAPI specifications. It works with Elasticsearch, OpenAPI and TypeScript. The repository describes itself as: Your window into all of your data.

Workflow steps

What it can do on your machine

Read from SKILL.md and the folder at commit 452e025. 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
Shell commands in SKILL.md call:
- npx
- pnpm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npx and pnpm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
- API_KEY
- ELASTIC_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Improve Oas loads about 4.8k tokens when it runs. Until then it costs about 67 tokens; SKILL.md has 2,309 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~67
When it runs · the whole SKILL.md, loaded when a task matches: ~4.8k

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 (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 2,309 words (~4,801 tokens).

“Add descriptions, examples, and code samples to a Kibana API area so that the generated OpenAPI specification is complete and useful for humans and AI agents.”
