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.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00084 | $0.02974 |
| Opus 5 | $0.00042 | $0.01487 |
| Sonnet 5 | $0.00017 | $0.00595 |
| Haiku 4.5 | $0.00008 | $0.00297 |
Grade A, and why
financial-insights 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 today.
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.
How it starts
The opening of the file, as written. The whole thing — 317 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Financial insights
Use this skill to answer questions about a user’s Link-connected financial data, including:
- Recent transactions
- Spending patterns
- Account balances
- Linked wallet sources
- Basic summaries derived from the user’s financial data
All commands are read-only. They do not move money, initiate payments, modify accounts, or expose payment credentials.
Safety and privacy
Do not retrieve financial data until the user is authenticated with the required source actions.
Only retrieve the data needed to answer the user’s request. Do not run every list command by default.
Do not expose sensitive identifiers, access tokens, credentials, or payment instrument details. Summarize financial information at the level needed to answer the user’s question.
If the user asks for an action that would move money, reference skills/create-payment-credential/SKILL.md instead.
Authentication
Before retrieving financial data, check whether the user is authenticated and whether the current session has the required source actions.
link-cli auth status --format json
When present, inspect authorization_details in the response for entries with type: "source" and the required actions. The field may be absent when the token endpoint did not return authorization details or when authentication comes from LINK_ACCESS_TOKEN; in that case, run only the minimum data command needed and handle a permission error as described below.
If the user is not authenticated, start a login that requests only the source actions needed for the requested data. If the user is already authenticated but one or more required source actions are missing, use auth upgrade instead of auth login. auth upgrade preserves the current session while the user approves the additional access and replaces it only after approval succeeds.
Use the minimum required source actions:
- Transactions processed through Link:
read_link_transactions - Transactions imported from bank connections:
read_external_transactions - Account balances:
read_balances - Data source details and descriptions:
read_source_details
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.

financial-insights is a skill published in the GitHub repository stripe/link-cli (751 stars, last pushed today), licensed MIT. It adds 84 tokens to every session and 2,974 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
