Blobless-safe git and PR history for this repo. An agent skill from BuilderIO/agent-native.

  • SKILL.md covers Never read history with blob…, Scripts, Reading the scores and Tuning
  • Runs TypeScript scripts from its folder; calls git and pnpm
  • What recently touched a file

What it does

System History is an agent skill from BuilderIO/agent-native. Blobless-safe git and PR history for this repo. Collects first-parent commits, scores systems against the repo's own baseline to separate fragile from fast-moving, lists recent changes to specific files as regression candidates, and reads PR diffs through GitHub. Use when you need to know how an area has been changing, what recently touched a file, or what a PR did.

Its SKILL.md is about 730 tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including scripts (for example `config.json`, `scripts/analyze.ts` and `scripts/collect.ts`).

It sits in Development. It works with Git and GitHub. The repository describes itself as: A framework for building agentic apps.

When your agent uses it

  • You need to know how an area has been changing
  • What recently touched a file

Example prompts

  • “/system-history”

Requirements

  • Node.js

What it can do on your machine

Read from SKILL.md and the folder at commit 1c2de07. 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

    Ships 5 files in scripts/ (TypeScript), which the agent can run.

    Shell commands in SKILL.md call:

    • git
    • pnpm

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git 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 no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

System History loads about 727 tokens when it runs. Until then it costs about 96 tokens; SKILL.md has 320 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~96
When it runs · the whole SKILL.md, loaded when a task matches
~727

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); the scripts in this folder are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 320 words (~727 tokens).
