Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.00479 |
| Opus 5 | $0.00000 | $0.00239 |
| Sonnet 5 | $0.00000 | $0.00096 |
| Haiku 4.5 | $0.00000 | $0.00048 |
Grade A, and why
dev-supabase scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
DEV-SUPABASE Agent (pointer)
Configure and use Supabase as a backend (Auth, Database, Storage, Realtime, Edge Functions).
Context
$ARGUMENTS
Delegate to the vendor toolkit
claude-base's prior dev-supabase content (48-line checklist) is superseded by supabase/agent-skills — Supabase's own toolkit, maintained by the Supabase team in sync with the current API (Auth, DB, Edge Functions, Realtime, Storage), goes deeper than a hand-maintained checklist on a backend the vendor owns. The repo ships two skills (client patterns + Postgres best-practices). The sibling dev-supabase skill already graduated to this pointer.
Install:
# Vendor publishes via marketplace (verify on their README):
claude plugin install supabase@supabase
# Fallback — clone and symlink both skills:
git clone --depth 1 https://github.com/supabase/agent-skills ~/dev/vendor-skills/supabase
ln -s ~/dev/vendor-skills/supabase/skills/supabase ./.claude/skills/supabase
ln -s ~/dev/vendor-skills/supabase/skills/supabase-postgres-best-practices \
./.claude/skills/supabase-postgres-best-practices

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

dev-supabase is a command published in the GitHub repository christopherlouet/claude-base (5 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 479 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
