What it does

Flexport Migration Deep Dive is an agent skill from jeremylongshore/tons-of-skills-marketplace. Migrate a legacy or v2-era Flexport integration to current v3 and MCP-aware contracts without unsafe concurrent production writers. Use when inventorying old endpoints, changing versions, or replacing custom workflows. Trigger with: "migrate Flexport integration", "upgrade Flexport v2", "adopt 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 a legacy contract inventory, current Flexport account version context, and an authorized cutover owner.

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

  • Inventorying old endpoints
  • Changing versions
  • Replacing custom workflows
  • With: migrate Flexport integration

Example prompts

  • “migrate Flexport integration”
  • “upgrade Flexport v2”
  • “adopt Flexport MCP”
  • “/flexport-migration-deep-dive”

Requirements

  • Compatibility (from SKILL.md): Requires a legacy contract inventory, current Flexport account version context, and an authorized cutover owner.
  • Pre-approved tools (allowed-tools): Read, Grep, Write, Edit

Workflow steps

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

  1. Inventory reality
  2. Map to documented targets
  3. Build tolerant readers
  4. Shadow reads only
  5. Cut over one writer
  6. Verify and retire

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 a legacy contract inventory, current Flexport account version context, and an authorized cutover owner.

    From compatibility in the SKILL.md frontmatter.

Context cost

Flexport Migration Deep Dive 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 85 tokens; SKILL.md has 413 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~85
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.

Controlled Flexport Integration Migration

Overview

Migration is a sequence of read-only comparison, explicit field mapping, shadow evaluation, and one controlled write owner. Never dual-book freight or dual-create trade records merely to compare systems.

Prerequisites

  • Endpoint/tool inventory with read/write classification
  • Captured account default version and any Flexport-Version overrides
  • Business-key mapping, rollback plan, and reconciliation owner

Instructions

Step 1: Inventory reality

Trace every legacy path, version header, response assumption, event name, expansion, credential, and mutation.

Step 2: Map to documented targets

Choose current v3 REST endpoints or MCP tools by outcome. Record unsupported fields/operations rather than guessing equivalents.

Step 3: Build tolerant readers

Accept documented envelopes and additive fields, preserve opaque identifiers, and add sanitized fixtures for old/new differences.

Step 4: Shadow reads only

Compare current and target read paths over an approved sample. Normalize only business facts and investigate discrepancies.

Step 5: Cut over one writer

Freeze the legacy mutation queue, reconcile in-flight operations, switch one authoritative writer, and retain a rapid rollback that cannot produce concurrent writes.

Step 6: Verify and retire

Reconcile provider resources, events, and local operation keys across the cutover window before removing old credentials/code.

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 v2-era shipment reader moves to v3 with an explicit version override and tolerant fields. Its booking path remains unchanged until a separate approved cutover can guarantee one writer and reconcile every in-flight booking.
