Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00040 | $0.03087 |
| Opus 5 | $0.00020 | $0.01543 |
| Sonnet 5 | $0.00008 | $0.00617 |
| Haiku 4.5 | $0.00004 | $0.00309 |
Grade A, and why
managing-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 4d 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.

Quick Reference
Supabase CLI enables local development, database migrations, Edge Functions deployment, and project management for Supabase projects.
Critical: Avoiding Interactive Mode
Supabase CLI can enter interactive mode which will hang Claude Code. Always use flags to bypass prompts:
| Command | WRONG (Interactive) | CORRECT (Non-Interactive) |
|---|---|---|
| Login | supabase login |
Use SUPABASE_ACCESS_TOKEN env var |
| Link project | supabase link |
supabase link --project-ref <ref> |
| Create project | supabase projects create |
supabase projects create <name> --org-id <id> --region <region> |
| Start local | supabase start |
supabase start (non-interactive by default) |
| Deploy functions | supabase functions deploy |
supabase functions deploy <name> --project-ref <ref> |
Never use in Claude Code:
supabase loginwithout token (opens browser)- Any command without
--project-refwhen not linked - Interactive prompts for organization/region selection
Always include:
SUPABASE_ACCESS_TOKENenvironment variable for authentication--project-refflag or pre-linked project- Explicit flags for all configuration options
Prerequisites
Installation Verification
supabase --version
# Expected: 2.x.x or higher
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 4d ago First seen · 447 lines · 40 tokens per session scan A 65edeb6ba47a
managing-supabase is a skill published in the GitHub repository FortiumPartners/ensemble (11 stars, last pushed today), licensed MIT. It adds 40 tokens to every session and 3,087 once invoked, about $0.0002 per session on Opus 5. 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.
