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.

What it costs to keep this loaded
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 | $0.00072 | $0.01799 |
| Opus 5 | $0.00036 | $0.00899 |
| Sonnet 5 | $0.00014 | $0.00360 |
| Haiku 4.5 | $0.00007 | $0.00180 |
Grade A, and why
mcp-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 12d 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.

Supabase MCP Skill
Interact with Supabase database via MCP tools, execute queries, writes, migrations, and diagnostics.
Scope
Applies to:
- Need to perform "database actions" on Supabase: query/statistics/export, write (after confirmation), migration (DDL), type generation, query logs/advisors
Does not apply to:
- Need to complete "integration implementation" in Next.js project (env/client code/minimal data access layer/project structure)
→ Useworkflow-ship-faster(Step 6: Supabase integration) for project-side setup; this skill only handles DB-side actions and gates

Postgres Best Practices (Bundled)
Ship Faster vendors Supabase's Postgres best practices inside the supabase skill (install supabase alongside this skill if you want these references available locally):
- Full guide:
supabase/references/postgres-best-practices/AGENTS.md - Individual rules:
supabase/references/postgres-best-practices/rules/*.md
Consult it when:
- Writing/reviewing/optimizing SQL queries
- Designing indexes, schema changes, or RLS policies
- Diagnosing performance, locking, or connection issues
When proposing changes, cite the relevant rule file path (for example: supabase/references/postgres-best-practices/rules/query-missing-indexes.md) and keep changes minimal.
File-based Pipeline (Pass Paths Only)
When integrating database operations into multi-step workflows, persist all context and artifacts to disk, passing only paths between agents/sub-agents.
Recommended directory structure (within project): runs/<workflow>/active/<run_id>/
- Input:
01-input/goal.md(requirements),01-input/context.json(known tables/fields/IDs) - Plan:
03-plans/sql.md(SQL to execute; write operations must be written here before confirmation) - Output:
05-final/result.md(conclusion + key numbers + SQL + truncated results) - Logs:
logs/events.jsonl(summary of each tool call; do not log sensitive field values)
What ships with it
1 file 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.

mcp-supabase is a skill published in the GitHub repository Heyvhuang/ship-faster (339 stars, last pushed 27d ago), licensed MIT. It adds 72 tokens to every session and 1,799 once invoked, about $0.0004 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 2026-08-30.
