Package Exports

aiignore-cli
aiignore-cli/dist/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (aiignore-cli) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

aiignore

One command to protect your secrets from all AI coding tools.

Every AI tool has a different ignore mechanism — .cursorignore, .geminiignore, .codeiumignore, .claude/settings.json, .aiignore — each with its own quirks and undocumented bypass bugs. aiignore scans your project, detects which tools you use, and generates the right config for each one.

Quick Start

npx aiignore-cli init

Or install globally:

npm install -g aiignore-cli
aiignore init

Requires Node.js 18+.

Why not just create the files manually?

You could. A .cursorignore takes 30 seconds to write. But:

Do you know that Cursor also needs .cursorignore, Claude Code needs settings.json deny rules, Gemini CLI needs .geminiignore, JetBrains needs .aiignore, and Windsurf still uses .codeiumignore?
Do you know that Cursor's ignore is "best-effort" with 2 known CVEs, that Gemini's negation patterns are broken, or that Copilot has no ignore file at all?
Do you want to research each tool's format every time you set up a new project?

aiignore does the research for you. The security data behind each tool is the real value — the CLI just applies it.

Commands

`aiignore init`

aiignore init

`aiignore verify`

aiignore verify

aiignore                             # same as aiignore init
aiignore init                        # auto-detect and generate
aiignore init --all                  # all tools, skip detection
aiignore init --only cursor          # single tool
aiignore init --only cursor,gemini   # multiple tools (comma-separated)
aiignore init --append               # add missing patterns to existing files
aiignore init --dry-run              # preview only
aiignore init --force                # overwrite existing files
aiignore init -q                     # quiet mode (no output)

aiignore verify                      # protection status table
aiignore verify --ci                 # exit 1 if unprotected
aiignore verify --strict             # exit 1 if any tool is unreliable
aiignore verify --json               # machine-readable output

aiignore list                        # show supported tools and aliases

Tool Support

Tool	File Generated	Reliability	Key Issue
Cursor	`.cursorignore`	Low	"best-effort", agent bypass, `@` reference bypass
Claude Code	`.claude/settings.json`	Medium	`Read()` deny covers Bash too (tested)
Copilot	guide only	None	no ignore file exists for individual devs
Gemini CLI	`.geminiignore`	Low	negation patterns broken, self-blocks `.env`/`.pem`
JetBrains AI	`.aiignore`	High	most reliable; AI redacts sensitive filenames
Windsurf	`.codeiumignore`	Medium	negation can't override `.gitignore`

What Gets Protected

Patterns are sourced from built-in defaults + security-related entries in your .gitignore:

Category	Patterns
Environment	`.env`, `.env.*`, `.env.local`
Credentials	`credentials.json`, `service-account.json`, `secret*`, `token.json`
Keys	`.pem`, `.key`, `.p12`, `.pfx`, `*.jks`
SSH	`.ssh/`, `id_rsa`, `id_ed25519`, `id_ecdsa*`
Cloud	`.aws/`, `.gcp/`, `.azure/`, `gcloud/`
App Secrets	`config/secrets.yml`, `config/master.key`, `vault.json`
Database	`.sqlite`, `.db`, `dump.sql`
Certificates	`.crt`, `.cer`, `*.ca-bundle`

Tool Aliases

--only accepts these names (comma-separated):

cursor                     -> Cursor
claude / claude-code       -> Claude Code
copilot                    -> GitHub Copilot
gemini / gemini-cli        -> Gemini CLI
jetbrains / jb             -> JetBrains AI
windsurf / codeium         -> Windsurf/Codeium

Run aiignore list to see all tools and aliases.

Limitations

No AI tool guarantees 100% file exclusion. All tools share a common weakness: agent/terminal modes can bypass ignore files by running shell commands directly. Copilot has no ignore mechanism at all for individual developers.

This tool is one layer of defense. For production secrets, also use a secrets manager, pre-commit hooks (gitleaks, trufflehog), and keep secrets out of your project directory entirely.

For per-tool details (CVEs, known bugs, tested behavior), see AI Coding Tool Security Reference.
