bex: Skill for Claude Code

.claude/skills/stripe-directory/SKILL.md

stripe-directory is a skill for Claude Code from bex-co/bex. It costs 73 tokens per session (1,449 once invoked), scanned A, original, Apache-2.0.

A directory search tool for finding businesses, software, service providers, and partners by industry, workflow, problem, or capability. It can also identify services that an agent can pay for and use directly.

In plain words
What is it for?
Finding and comparing vendors, tools, partners, and service providers, and, where supported, purchasing or consuming a service through its payment endpoint.
Why use it?
It turns a broad request into a short list of relevant providers, so you do not have to search through unrelated results yourself.

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.

Security

Grade A, and why

stripe-directory scanned grade A with 1 finding 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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Turn a vague market need into a short, relevant shortlist with stripe directory search. Use this even when the user never says “Stripe Directory” — any request to find vendors, tools, partners, or providers for a vertical, workflow, pain point, or job-to-be-done.

Most requests are discovery — find and compare services. That is the core job below. Some services are also MPP-supported (MPP = Machine Payment Protocol), meaning you (the agent) can pay their HTTP 402 (Payment Required) endpoint and consume them directly. When the user actually wants to use or buy a service, present those results and offer to purchase — see “Purchasing” at the end.

Process

  1. Clarify only what’s missing: buyer/vertical, job-to-be-done, must-have capability, geography (only if it matters).

  2. Search iteratively: stripe directory search "<query>" --format json

    • Short noun phrases, one angle per query; run 1-3, then broaden/narrow on results.
    • Angles to cover: vertical → workflow → pain point → adjacent. Two examples:
      • services/trades: vertical (electrician software, electrical contractor) → workflow (field service management, dispatch invoicing estimates) → pain point (job scheduling, quote automation) → adjacent (home services automation, contractor crm).
      • SaaS/software: vertical (b2b saas billing, developer tools) → workflow (subscription management, usage-based metering) → pain point (failed payment recovery, revenue recognition) → adjacent (analytics dashboards, customer onboarding).
    • Hard constraints → try filter flags if available: --countries-supported=US, --has-stripe-app=true, --link-supported=true, --stripe-projects-supported=true, --mpp-supported. Note: as of directory v0.3.0 the server ignores filter flags — only --limit (max 10) and --page affect results (stripe directory search --help → “Filter flags have no server-side equivalent yet and are ignored”). Keep queries narrow via the search term itself; re-check --help before relying on filters.
    • If the user wants to use/buy a service, also pass --mpp-supported in at least one search to find results you can pay for programmatically (even if currently server-ignored, it documents intent for when the server honors it).
    • Sparse niche? Raise --limit (max 10) and try the next --page before concluding it’s empty.

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.
