straddle-plan

straddle-plan is a skill for Claude Code, Codex from straddleio/ai. It costs 69 tokens per session (2,257 once invoked), scanned A, original, MIT.

A guided planning skill for building a Straddle payment integration, tailored to your use case, programming language, and payment needs. Straddle is a payment service with features such as bank payments and webhooks, which are messages sent when an event occurs.

In plain words
What is it for?
Use it to plan a sandbox integration, map your data to Straddle, design payment flows, and outline webhook handlers.
Why use it?
It turns an unfamiliar payment integration into a structured plan covering the relevant entities, API steps, code examples, webhooks, and compliance notes.

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

straddle-plan 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 3d 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.

How it starts

The opening of the file, as written. The whole thing — 238 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Purpose

Run a guided conversation (5-8 questions) that produces a complete Straddle integration plan. The plan covers entity mapping, API flows, code examples, webhook handlers, and compliance notes -- all tailored to the developer's specific use case and SDK language.

The plan is the artifact the developer uses to build their sandbox integration.

Scope boundaries

  • Execute API calls -> use sandbox-test
  • Answer ad-hoc integration questions -> use straddle-integrate
  • Set up MCP/CLI/keys -> use setup
  • Explain statuses -> use explain-status

Point users to the appropriate skill if they ask for something outside scope.

Reference files

Read before generating each plan section. Shared with straddle-integrate:

Topic Reference
Entities, statuses, webhooks, ACH <../straddle-integrate/references/domain.md>
Embed: onboarding, accounts, headers <../straddle-integrate/references/embed.md>
Pay by Bank: customer, bridge, payments <../straddle-integrate/references/pay-by-bank.md>
SDKs, Bridge Widget, errors <../straddle-integrate/references/sdk.md>

Doc search enforcement

Reference files contain stable structural and behavioral knowledge. Enumerated factual lists (return codes, event names, numeric limits) have been replaced with links to authoritative documentation pages.

Doc search tools:

  • search_docs MCP tool -- SDK and API reference (method signatures, parameters, code examples). Always pass language param.
  • Product docs -- search by POSTing to https://docs.straddle.com/mcp with {"jsonrpc":"2.0","method":"tools/call","params":{"name":"search_straddle_docs","arguments":{"query":"YOUR_QUERY"}},"id":1} and header Accept: application/json, text/event-stream. Returns payment guides, compliance, sandbox testing.

Default to search_docs for any code or API question.

For EACH section of the output plan:

  1. Read the relevant reference file for structural baseline
  2. Follow all documentation links in the reference file for current values
  3. Use search_docs (pass language param) for method signatures and code examples
  4. Search product docs (POST to https://docs.straddle.com/mcp) for current guides and compliance info
  5. Compare all sources. MCP results win on conflicts (they are live). Flag discrepancies.

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.
