faasjs-utils-dataA skill your agent uses when working with @faasjs/utils or FaasJS data helpers: deepMerge, streamToString, stringToStream, objectToStream, streamToObject, parseJson, parseObjectFromJson…
Faasjs Utils Data is an agent skill from faasjs/faasjs. Use when working with @faasjs/utils or FaasJS data helpers: deepMerge, streamToString, stringToStream, objectToStream, streamToObject, parseJson, parseObjectFromJson, parseArrayFromJson, parseYaml, z validation helpers, isObjectRecord, parseSchemaValue, formatSchemaError, and isPathInsideRoot.
Its SKILL.md is about 400 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `references/guidelines/json.md`, `references/guidelines/utils.md` and `references/guidelines/valid.md`).
It works with Zod. The repository describes itself as: 🚀 FaasJS is an agent-friendly full-stack TypeScript framework for building predictable, type-safe applications with minimal dependencies. The licence is MIT.
5 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 8136384. It shows what the files ask for, not the result of running them.
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.
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.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Faasjs Utils Data loads about 398 tokens when it runs, and up to ~4.1k if it reads all its reference files. Until then it costs about 78 tokens; SKILL.md has 159 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.
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.

A skill your agent uses when working with @faasjs/utils or FaasJS data helpers: deepMerge, streamToString, stringToStream, objectToStream, streamToObject, parseJson, parseObjectFromJson…. Faasjs Utils Data is an agent skill from faasjs/faasjs. Use when working with @faasjs/utils or FaasJS data helpers: deepMerge, streamToString, stringToStream, objectToStream, streamToObject, parseJson, parseObjectFromJson, parseArrayFromJson, parseYaml, z validation helpers, isObjectRecord, parseSchemaValue, formatSchemaError, and isPathInsideRoot.
Faasjs Utils Data fits situations like: working with @faasjs/utils; faasJS data helpers: deepMerge; parseObjectFromJson; parseArrayFromJson.
Run `npx skills add faasjs/faasjs --skill faasjs-utils-data -a claude-code`. Or copy the skill folder (skills/faasjs-utils-data in faasjs/faasjs) into .claude/skills/faasjs-utils-data in your project. Claude Code loads it when a task matches its description.
Run `npx skills add faasjs/faasjs --skill faasjs-utils-data -a codex`. Or copy the skill folder (skills/faasjs-utils-data in faasjs/faasjs) into .agents/skills/faasjs-utils-data in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add faasjs/faasjs --skill faasjs-utils-data -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/faasjs-utils-data, .gemini/skills/faasjs-utils-data, .github/skills/faasjs-utils-data and .opencode/skills/faasjs-utils-data in your project.
SKILL.md names no scripts, command-line tools or credentials: Faasjs Utils Data is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Faasjs Utils Data is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 398 tokens (SKILL.md is roughly 1.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 3.7k tokens, read only when the agent opens those files.
