What it does

Flexport Reference Architecture is an agent skill from jeremylongshore/tons-of-skills-marketplace. Analyze and design a Flexport integration that separates REST v3 resources, MCP tools, webhook ingress, approval, and reconciliation. Use when producing an architecture, threat model, or service boundary. Trigger with: "design Flexport architecture", "Flexport MCP architecture", "Flexport integration boundaries".

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/official-docs.md`). Compatibility notes: Requires approved Flexport capabilities, account context, and organizational security/data constraints.

It sits in Backend & APIs, covering Webhooks, Accounting and bookkeeping and MCP servers. It works with Model Context Protocol. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.

When your agent uses it

  • Producing an architecture
  • Service boundary
  • With: design Flexport architecture
  • Flexport MCP architecture

Example prompts

  • “design Flexport architecture”
  • “Flexport MCP architecture”
  • “Flexport integration boundaries”
  • “/flexport-reference-architecture”

Requirements

  • Compatibility (from SKILL.md): Requires approved Flexport capabilities, account context, and organizational security/data constraints.
  • Pre-approved tools (allowed-tools): Read, Grep, Write, Edit

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Draw provider surfaces
  2. Place credential boundaries
  3. Separate control and data
  4. Add durable state
  5. Add reconciliation
  6. Prove failure paths

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Grep
    • Write
    • Edit

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are yaml).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • api.flexport.com
    • mcp.flexport.com

    Also links to:

    • apidocs.flexport.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Requires approved Flexport capabilities, account context, and organizational security/data constraints.

    From compatibility in the SKILL.md frontmatter.

Context cost

Flexport Reference Architecture loads about 1.1k tokens when it runs, and up to ~1.3k if it reads all its reference files. Until then it costs about 87 tokens; SKILL.md has 402 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~87
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Flexport REST, MCP, and Webhook Architecture

Overview

Use three explicit provider planes: REST v3 for resource operations, MCP Streamable HTTP JSON-RPC for permissioned assistant tools, and signed webhooks for notifications. Join them only through durable application policy and reconciliation.

Prerequisites

  • Capability inventory split into reads, mutations, events, and assistant tools
  • Identity, account, environment, and data-flow boundaries
  • Business approval, operation ledger, queue, and recovery requirements

Instructions

Step 1: Draw provider surfaces

Show api.flexport.com, mcp.flexport.com/mcp, and public HTTPS webhook ingress as distinct external nodes.

Step 2: Place credential boundaries

Use endpoint-scoped OAuth clients per REST workload, authenticated MCP sessions with documented tool roles, and a separate webhook secret.

Step 3: Separate control and data

Put business approval and policy before booking/trade mutations; keep payload handling in minimized data services.

Step 4: Add durable state

Persist operation keys, provider references, event dedupe state, cursor/link checkpoints, and redacted outcomes.

Step 5: Add reconciliation

Connect events and uncertain outcomes to authorized REST/resource reads. Never make webhook delivery the sole source of truth.

Step 6: Prove failure paths

Model token-cache failure, permission denial, additive schema change, duplicate/missing event, ambiguous mutation, and rollback.

Authentication

REST calls authenticate with a cached OAuth 2.0 client-credentials Bearer token using audience https://api.flexport.com, or an explicitly accepted broad API key. Use distinct credentials per workload and never log credentials or tokens. MCP calls use the authenticated connection to https://mcp.flexport.com/mcp and remain subject to each tool's documented account permissions.

Tool Discipline

Use Read and Grep for discovery and evidence. Use Write or Edit only for the approved artifact, code, configuration, test, or receipt described by this workflow; do not make an unapproved Flexport-side change.

Output

  • Scoped decision or implementation artifact
  • Redacted operation and validation receipt
  • Failure, rollback, and follow-up ownership record

Return a machine-reviewable receipt in this shape; adapt the operation values, but never place credentials or provider payloads in it:

yaml
surface: rest-v3
operation: shipment-read
decision: approved
outcome: verified
evidence:
  release_sha: recorded-out-of-band
  provider_reference: redacted
rollback_owner: logistics-platform

Examples

A booking assistant queries rates through MCP, sends an exact candidate to an approval service, and records one operation key before booking. Signed events enqueue notifications, while a reconciler reads provider state to close gaps.

Error Handling

REST and MCP contracts collapsedSplit transport, auth/session, errors, and pagination before implementation.
