What it does
Flexport SDK Patterns is an agent skill from jeremylongshore/tons-of-skills-marketplace. Design typed adapters for Flexport REST v3 and the Flexport MCP server while preserving their different contracts. Use when building a client library, response parser, MCP transport, or shared integration boundary. Trigger with: "build Flexport client", "type Flexport responses", "connect Flexport MCP".
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 current Flexport v3 and MCP schemas plus a typed application language or runtime validation library.
It sits in Agent Workflows, covering 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
- Building a client library
- Response parser
- Shared integration boundary
- With: build Flexport client
Example prompts
- “build Flexport client”
- “type Flexport responses”
- “connect Flexport MCP”
- “/flexport-sdk-patterns”
Requirements
- Compatibility (from SKILL.md): Requires current Flexport v3 and MCP schemas plus a typed application language or runtime validation library.
- Pre-approved tools (allowed-tools): Read, Grep, Write, Edit
Workflow steps
6 steps, taken from the step headings in SKILL.md.
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:
ReadGrepWriteEdit
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.commcp.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 current Flexport v3 and MCP schemas plus a typed application language or runtime validation library.
From compatibility in the SKILL.md frontmatter.
Context cost
Flexport SDK Patterns 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 82 tokens; SKILL.md has 412 words of instructions outside code blocks.
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 Dual-Surface Client Contracts
Overview
REST resources and MCP tools are two distinct public surfaces. Keep separate transports, authentication/session handling, error models, and pagination adapters behind business-level interfaces.
Prerequisites
- Inventory of required REST endpoints and MCP tools
- Pinned account/version behavior and schema snapshot date
- Runtime validation, redaction, timeout, and test-fixture strategy
Instructions
Step 1: Define business ports
Express outcomes such as readShipment, browseRisk, or evaluateRate; keep HTTP paths and MCP JSON-RPC details behind adapters.
Step 2: Build the REST adapter
Use base https://api.flexport.com, Bearer authentication, optional Flexport-Version, documented envelopes, status/code/message errors, and link-style pagination where documented.
Step 3: Build the MCP adapter
Use Streamable HTTP JSON-RPC at POST https://mcp.flexport.com/mcp. Treat the per-tool paths shown in reference pages as synthetic documentation, not literal REST routes.
Step 4: Validate at runtime
Accept documented additive fields, preserve opaque identifiers/cursors, and reject missing required fields without guessing replacements.
Step 5: Normalize evidence, not schemas
Return a stable application result and surface provider metadata separately; do not force REST and MCP payloads into one lossy provider model.
Step 6: Contract-test both surfaces
Replay sanitized official-shape fixtures for success, pagination, permission errors, additive fields, and ambiguous transport failure.
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.
Show full SKILL.md (170 more words)Show less
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:
surface: rest-v3
operation: shipment-read
decision: approved
outcome: verified
evidence:
release_sha: recorded-out-of-band
provider_reference: redacted
rollback_owner: logistics-platformExamples
The application calls one ShipmentReader interface. Its REST adapter follows shipment pagination links; its MCP adapter sends tools/call for browse_shipments and advances end_cursor, while both return the same minimal internal summary.
Error Handling
| Failure | Response |
|---|---|
| Synthetic tool path called as REST | Replace it with an MCP JSON-RPC tools/call request. |
| Unknown additive field | Preserve or ignore it safely; do not fail a tolerant reader. |
| Required field absent | Quarantine the response and compare against the current schema. |
| Transport outcome ambiguous | Reconcile the operation rather than blind-retrying a mutation. |
