supabase-upgrade-migrationUpgrade Supabase SDK and CLI versions with breaking-change detection and automated code migration.
Supabase Upgrade Migration is an agent skill from jeremylongshore/tons-of-skills-marketplace. Upgrade Supabase SDK and CLI versions with breaking-change detection and automated code migration. Use when upgrading @supabase/supabase-js (v1→v2 or minor bumps), migrating auth/realtime/storage APIs, or updating the Supabase CLI. Trigger with phrases like "upgrade supabase", "supabase breaking changes", "migrate supabase v2", "update supabase SDK".
Its SKILL.md is about 2.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/errors.md`, `references/examples.md` and `references/implementation.md`). Compatibility notes: Designed for Claude Code
It sits in Development, covering Code migrations and Anomaly detection. It works with Supabase and Python. 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.
3 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.
Pre-approves these tools, so the agent can use them without asking each time:
ReadWriteEditBash(npm:*)Bash(npx:*)Bash(pip:*)Bash(supabase:*)Bash(git:*)GrepGlobFrom allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:

Links to these hosts (documentation or services it may open):
github.comsupabase.comFrom URLs in SKILL.md, links to its own repository left out.
Names these keys or tokens, usually read from environment variables:
NEXT_PUBLIC_SUPABASE_ANON_KEYFrom names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Designed for Claude Code
From compatibility in the SKILL.md frontmatter.
Supabase Upgrade Migration loads about 2.8k tokens when it runs, and up to ~3.3k if it reads all its reference files. Until then it costs about 95 tokens; SKILL.md has 553 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.
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.

Covers the v1-to-v2 migration path (auth method renames, data/error destructuring, realtime API overhaul), minor version bumps, @supabase/ssr adoption, and Python SDK upgrades via pip install --upgrade supabase.

error.message string parsing | error.code enum (PGRST116, etc.) | Reliable error matching |
.single() returns error on 0 rows | .maybeSingle() for optional rows | New method for nullable results |
supabase.from('t').on('INSERT', cb).subscribe() | supabase.channel('c').on('postgres_changes', ...).subscribe() | Realtime v2 channel API |

Going by SKILL.md and its folder, Supabase Upgrade Migration needs the command-line tools its instructions call (npm, pip, npx, supabase, git and python) and credentials named NEXT_PUBLIC_SUPABASE_ANON_KEY. Our summary lists: Python 3; Node.js; A credential in NEXT_PUBLIC_SUPABASE_ANON_KEY. Its frontmatter pre-approves these tools: Read, Write, Edit, Bash(npm:*), Bash(npx:*), Bash(pip:*), Bash(supabase:*), Bash(git:*), Grep, Glob. Compatibility (from SKILL.md): Designed for Claude Code.
SKILL.md names 2 domains. As links in the text: github.com and supabase.com. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Supabase Upgrade Migration is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.8k tokens (SKILL.md is roughly 11k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 562 tokens, read only when the agent opens those files.
