Appfolio Upgrade Migration

What it does

When your agent uses it

• Databases work in your project

Example prompts

• “appfolio upgrade”
• “/appfolio-upgrade-migration”

Requirements

• Compatibility (from SKILL.md): Designed for Claude Code
• Pre-approved tools (allowed-tools): Read, Write, Edit, Bash(npm:*), Bash(curl:*), Grep

Workflow steps

8 steps, taken from the first numbered list in SKILL.md.

1. 1Run version detection to compare your active API version against the latest.
2. 2Review the AppFolio changelog for breaking changes between the two versions.
3. 3Apply schema migration transforms to property and tenant response objects.
4. 4Update endpoint URLs from the old version prefix to the new one.
5. 5Switch pagination from offset to cursor-based if required by the new version.
6. 6Run the smoke test suite against staging to verify all endpoints respond.
7. 7Deploy to production with the rollback strategy enabled.
8. 8Monitor error logs for 410/401 responses indicating missed migration steps.

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
  • Write
  • Edit
  • Bash(npm:*)
  • Bash(curl:*)
  • Grep

  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 typescript).

  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:

  • acme.appfolio.com

  Also links to:

  • appfolio.com
  • engineering.appfolio.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

  Designed for Claude Code

  From compatibility in the SKILL.md frontmatter.

Context cost

Appfolio Upgrade Migration loads about 1.3k tokens when it runs. Until then it costs about 31 tokens; SKILL.md has 338 words of instructions outside code blocks.

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

~31

When it runs · the whole SKILL.md, loaded when a task matches

~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.
