link-cli: Instructions file for Codex

AGENTS.md

link-cli AGENTS.md is an instructions file for Codex, OpenCode from stripe/link-cli. It costs 300 tokens per session, scanned A, original, MIT.

A repository guide for Stripe's `link-cli`, stored as an `AGENTS.md` instruction file. It explains how to use the installed Turborepo version, including where to find its local documentation and configuration.

In plain words
What is it for?
Use it before changing Turborepo configuration or commands, to resolve the correct installed package, read its matching documentation, and understand how the managed guidance block is maintained.
Why use it?
Turborepo behavior can differ between versions and workspaces, especially in a monorepo, which is a repository containing multiple related projects. The guide reduces the risk of running the wrong command or editing configuration based on outdated assumptions.

Written for Codex and OpenCode: the file is AGENTS.md.

This is stripe/link-cli's own configuration. It tells Codex and OpenCode how to work on link-cli itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything link-cli configures →

About the project

stripe/link-cli is a command-line tool that lets agents obtain temporary payment credentials from a Link wallet for approved purchases without exposing the user's real card details. It is used by agents to complete web checkouts or programmatic payments while requiring purchase approval. The catalogue entries provide components for integrating the CLI with agents.

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.

Security

Grade A, and why

link-cli AGENTS.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 5d 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.

What it actually says

This is NOT the Turborepo you know

Turborepo configuration, task behavior, and CLI commands can vary between installed versions and may differ from your training data. Resolve the turbo package from this file's directory or relevant workspace; in monorepos, it may not be visible from the repository root. For example, run node -p "require.resolve('turbo/package.json')" from a workspace that depends on turbo.

Read docs/README.md inside that installed package first, then read the relevant pages from its docs/ directory before changing Turborepo configuration or commands. Heed deprecation notices. These bundled docs match the installed package version and are available without network access.

This block is written and re-added by turbo before repository-scoped commands when an AI agent is detected. In the Turborepo source repository, its template is defined in crates/turborepo-cli/src/cli/agent_guidance.rs. Removing the managed block while updates are enabled means a later qualifying invocation will add it again. Set "agentGuidance": false in the root turbo.json or turbo.jsonc to opt out; this does not remove an existing block. Keep the block committed with your work to avoid an uncommitted change on the next agent invocation.

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.
