What is link-cli CLAUDE.md?

Project instructions for Link CLI, a command-line tool that gets secure, one-time payment credentials from a Link wallet. It covers a pnpm and Turborepo monorepo, meaning one repository containing multiple related packages.

Use it when working on the Link SDK or CLI, installing dependencies, building, running tests, checking types, or formatting code.

It gives coding agents the project layout, required commands, and testing instructions so changes are made and checked consistently across the packages.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5	$0.03641	$0.03641
Opus 5	$0.01820	$0.01820
Sonnet 5	$0.00728	$0.00728
Haiku 4.5	$0.00364	$0.00364

Security

Grade A, and why

link-cli CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Project Overview

Link CLI — lets agents get secure, one-time-use payment credentials from a Link wallet. pnpm + Turborepo monorepo:

@stripe/link-sdk (packages/sdk): Typed Link API client and resource implementations. It accepts accessToken or getAccessToken; it does not own OAuth state. Entry: src/index.ts.
@stripe/link-cli (packages/cli): Commander.js + Ink/React CLI that consumes @stripe/link-sdk. Entry: src/cli.tsx.

Commands

pnpm install                    # install dependencies
pnpm run build                  # build all packages (turbo)
pnpm run dev                    # watch mode
pnpm run test                   # run all tests
pnpm run typecheck              # type-check all packages
pnpm biome check .              # lint + format check (CI)
pnpm run check                  # lint + format with auto-fix

Run a single test:

cd packages/cli && pnpm vitest run src/utils/__tests__/line-item-parser.test.ts

The CLI integration tests in packages/cli/src/__tests__/cli.test.ts run against the compiled dist/cli.js. Run pnpm run build before running them if the source has changed.

Run the CLI locally:

node packages/cli/dist/cli.js <command>

Architecture

SDK Resources

Defined in packages/sdk/src/resources/interfaces.ts:

ISpendRequestResource — CRUD + request-approval for spend requests

The SDK only accepts credentials. Device authorization, refresh-token persistence, login state, and auth-specific errors live under packages/cli/src/auth/.

CLI Command Structure

Commands in packages/cli/src/cli.tsx (incur framework). Each has two output modes:

Interactive (default): Ink/React components from packages/cli/src/commands/
JSON (--format json): JSON to stdout, errors as JSON with code and message fields with exit code 1

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
