What it does
Effect V3 To V4 is an agent skill from NiceEval/NiceEval. Use when migrating a codebase from Effect v3 to Effect v4, upgrading effect or any @effect/ package across the v3/v4 boundary.
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: build eval for your agent in 10 mins.
When your agent uses it
- Migrating a codebase from Effect v3 to Effect v4
- Upgrading effect
- Any @effect/ package across the v3/v4 boundary
Example prompts
- “/effect-v3-to-v4”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Set up and validate the canonical v4 and v3 reference checkouts described below.
- Read .repos/effect/MIGRATION.md once and list .repos/effect/migration/ for the guide index.
- Migrate package manifests first: remove consolidated packages and align every retained Effect package on one exact v4 version.
- Run the repository typecheck to obtain the initial error inventory.
- For each error, search migration/v3-to-v4.md for the exact symbol, then escalate through the topic guide and exact source as needed. Never…
- Finish only after typecheck is clean; run the relevant tests and report their outcome honestly.
What it can do on your machine
Read from SKILL.md and the folder at commit 97f06fe. 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:
rggitnode
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:
github.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.
Context cost
Effect V3 To V4 loads about 1.1k tokens when it runs. Until then it costs about 36 tokens; SKILL.md has 463 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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 463 words (~1,074 tokens).
“This is NiceEval's repository-local adaptation of the official Effect migration skill. Drive every rename, removal, and signature change from upstream migration data; do not guess replacements.”
