What it does
Agent Builder Tool Review is an agent skill from elastic/kibana, published by the product's own GitHub organization. Review Agent Builder tool registrations for availability scoping, MCP hygiene, description quality, return value design, single responsibility, and annotation correctness. Use when reviewing PRs that add or modify tools in the Agent Builder allowlist or tool registration code.
Its SKILL.md is about 2.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `agents/openai.yaml` and `references/common-issues.md`).
It sits in AI & LLM Engineering, covering Building AI agents. It works with Model Context Protocol and Elasticsearch. The repository describes itself as: Your window into all of your data.
When your agent uses it
- Reviewing PRs that add
- Modify tools in the Agent Builder allowlist
- Tool registration code
Example prompts
- “/agent-builder-tool-review”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Find the registering plugin's kibana.jsonc and feature registration (look for features.registerKibanaFeature or…
- Check if the plugin or feature has runtime gates: project-type restrictions (supportedProjectTypes), license requirements…
- If gated by a runtime condition: verify the tool has an availability handler matching those conditions. If the handler checks…
- If not gated: confirm the tool genuinely works across all project types and deployment modes
What it can do on your machine
Read from SKILL.md and the folder at commit ee7c86b. 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
Agent Builder Tool Review loads about 2.9k tokens when it runs, and up to ~4.5k if it reads all its reference files. Until then it costs about 76 tokens; SKILL.md has 1,369 words of instructions outside code blocks.
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 1,369 words (~2,854 tokens).
