What it does
Protected Files is an agent skill from bradygaster/squad. Zero-dependency bootstrap files that must never import npm packages or SDK code
Its SKILL.md is about 710 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It works with npm. The repository describes itself as: Squad: AI agent teams for any project. The licence is MIT.
Example prompts
- “/protected-files”
Requirements
- Node.js
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Add it to the Protected File List table above
- Write a matching zero-dependency regression test (see detect-squad-dir-zero-deps.test.ts for the pattern)
- Add — zero dependencies marker in the file header
What it can do on your machine
Read from SKILL.md and the folder at commit 1fd7e03. 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
Protected Files loads about 712 tokens when it runs. Until then it costs about 24 tokens; SKILL.md has 315 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.

- earned — CLI startup crashes when bootstrap files import SDK code
Context
The CLI (squad-cli) has bootstrap utilities that run before the Squad SDK is loaded. If these files import SDK code (e.g., FSStorageProvider, anything from squad-sdk), the CLI breaks at startup — no helpful error, just a crash.
This skill applies when:
- Touching any file in
packages/squad-cli/src/cli/core/ - Running sweeping refactors (e.g., "convert all
fscalls toStorageProvider") - Adding new bootstrap utilities
Protected File List
| File | Purpose |
|---|---|
packages/squad-cli/src/cli/core/detect-squad-dir.ts | Finds .squad/ directory at startup — runs before SDK init |
packages/squad-cli/src/cli/core/errors.ts | Error classes (SquadError, fatal()) — used by all CLI entry points |
packages/squad-cli/src/cli/core/gh-cli.ts | GitHub CLI wrapper — uses only node:child_process and node:util |
packages/squad-cli/src/cli/core/output.ts | Color/emoji console output — pure ANSI codes, zero imports |
packages/squad-cli/src/cli/core/history-split.ts | Separates portable knowledge from project data — pure string logic |
Rules
- ❌ NEVER convert these files to use
FSStorageProvider,StorageProvider, or any SDK abstraction - ❌ NEVER add
importorrequirestatements referencing packages outsidenode:*built-ins - ✅ ONLY use
node:fs,node:path,node:child_process,node:util, and other Node.js built-in modules - ✅ DO check this list before sweeping refactors
- ✅ LOOK for
— zero dependenciesmarkers in file headers as a signal
SDK/CLI Package Boundary
The packages/squad-cli/src/cli/core/ directory contains a mix of early-startup bootstrap utilities and later SDK-dependent modules. The protected list above is the authoritative set of zero-dependency bootstrap files. If you need to add SDK imports to another core/ file, verify it is not in the protected list and confirm the SDK is loaded at that point in the startup sequence.
Anti-Patterns
- Converting all
fscalls toStorageProviderwithout checking this list first - Adding
import { X } from '@bradygaster/squad-sdk'to a bootstrap file - Assuming every file in
core/can safely import SDK code
Adding New Bootstrap Utilities
When adding a new file that runs before SDK init:
- Add it to the Protected File List table above
- Write a matching zero-dependency regression test (see
detect-squad-dir-zero-deps.test.tsfor the pattern) - Add
— zero dependenciesmarker in the file header
Regression tests guard these files, but prevention is better than detection.

What does Protected Files do?
Zero-dependency bootstrap files that must never import npm packages or SDK code. Protected Files is an agent skill from bradygaster/squad.
How do I install Protected Files in Claude Code?
Run `npx skills add bradygaster/squad --skill protected-files -a claude-code`. Or copy the skill folder (.copilot/skills/protected-files in bradygaster/squad) into .claude/skills/protected-files in your project. Claude Code loads it when a task matches its description.
How do I install Protected Files in Codex?
Run `npx skills add bradygaster/squad --skill protected-files -a codex`. Or copy the skill folder (.copilot/skills/protected-files in bradygaster/squad) into .agents/skills/protected-files in your project. Codex loads it when a task matches its description.
Can I use Protected Files in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add bradygaster/squad --skill protected-files -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/protected-files, .gemini/skills/protected-files, .github/skills/protected-files and .opencode/skills/protected-files in your project.
What does Protected Files need to run?
SKILL.md names no scripts, command-line tools or credentials: Protected Files is instructions for the agent only. Our summary lists: Node.js.
Does Protected Files access the network?
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.
Is Protected Files safe to install?
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.
What licence does Protected Files use?
Protected Files is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Protected Files use?
About 712 tokens (SKILL.md is roughly 2.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
