What it does

Migrate Frontend Forms is an agent skill from getsentry/sentry, published by the product's own GitHub organization. Guide for migrating forms from the legacy JsonForm/FormModel system to the new TanStack-based form system.

Its SKILL.md is about 6.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Frontend & Design. It works with TanStack and Sentry. The repository describes itself as: Developer-first error tracking and performance monitoring.

When your agent uses it

  • Frontend & Design work in your project

Example prompts

  • “/migrate-frontend-forms”

What it can do on your machine

Read from SKILL.md and the folder at commit 87d1203. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • pnpm

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

  • Network

    No URLs in SKILL.md. Its commands use pnpm, which can reach the network depending on how they are called.

    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.

Context cost

Migrate Frontend Forms loads about 6.1k tokens when it runs. Until then it costs about 32 tokens; SKILL.md has 1,401 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~32
When it runs · the whole SKILL.md, loaded when a task matches
~6.1k

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,401 words (~6,057 tokens).

“This skill helps migrate forms from Sentry's legacy form system (JsonForm, FormModel) to the new TanStack-based system.”
