Flexport Upgrade Migration

What it does

When your agent uses it

• Changing the Flexport-Version header
• Testing a new schema
• Responding to added fields and event types
• With: upgrade Flexport API

Example prompts

• “upgrade Flexport API”
• “change Flexport version”
• “handle Flexport schema change”
• “/flexport-upgrade-migration”

Requirements

• Compatibility (from SKILL.md): Requires access to current Flexport version documentation, account version context, contract tests, and a rollback owner.
• Pre-approved tools (allowed-tools): Read, Grep, Write, Edit

Workflow steps

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

1. 1Discover effective versions
2. 2Classify changes
3. 3Harden readers
4. 4Test with overrides
5. 5Canary one cohort
6. 6Change default last

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 access to current Flexport version documentation, account version context, contract tests, and a rollback owner.

  From compatibility in the SKILL.md frontmatter.

Context cost

Flexport Upgrade Migration 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 92 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

~92

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

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.
