What it does

Review Crds is an agent skill from agent-substrate/substrate. Reviews CRDs for compliance with Kubernetes API conventions.

Its SKILL.md is about 230 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/api-conventions.md`).

It sits in DevOps & Cloud, covering Container orchestration. It works with Kubernetes. The repository describes itself as: Agent Substrate: the core system. The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Container orchestration

Example prompts

  • “Use the review-crds skill to review CRDs for compliance with Kubernetes API conventions”
  • “/review-crds”

What it can do on your machine

Read from SKILL.md and the folder at commit 296e329. 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 (its code samples are json).

    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

Review Crds loads about 228 tokens when it runs, and up to ~29k if it reads all its reference files. Until then it costs about 18 tokens; SKILL.md has 98 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~18
When it runs · the whole SKILL.md, loaded when a task matches
~228
With references · SKILL.md plus every file in references/, read only if the agent opens them
~29k

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.
