At a glance

Where a configuration value belongs — app config schema, agent-native.config.ts, or an environment variable — and how the layers resolve.

  • Tasks that involve Secrets management
  • SKILL.md covers The rule, Where a value goes, Adding a field and Resolution order, plus 3 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Configuration is an agent skill from BuilderIO/agent-native. Where a configuration value belongs — app config schema, agent-native.config.ts, or an environment variable — and how the layers resolve. Use before adding an env var, a configure/set function, a plugin option, or a register function, and when deciding whether something is config or a registry.

Its SKILL.md is about 2.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in DevOps & Cloud, covering Secrets management. The repository describes itself as: A framework for building agentic apps.

When your agent uses it

  • Tasks that involve Secrets management

Example prompts

  • “/configuration”

What it can do on your machine

Read from SKILL.md and the folder at commit e16da0c. 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 typescript).

    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

Configuration loads about 2.1k tokens when it runs. Until then it costs about 78 tokens; SKILL.md has 1,120 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~78
When it runs · the whole SKILL.md, loaded when a task matches
~2.1k

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

Without a licence we can't republish the file, so here is its outline and opening line. It has 1,120 words (~2,149 tokens).

“Core had 301 distinct environment variables and only 48 of them were secrets. The other 253 are product decisions that landed in process.env because at the call site that needed them, nothing else was reachable. This skill exists so the…”
