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 | $0.00032 | $0.00331 |
| Opus 5 | $0.00016 | $0.00166 |
| Sonnet 5 | $0.00006 | $0.00066 |
| Haiku 4.5 | $0.00003 | $0.00033 |
Grade A, and why
database-schema-reviewer 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 9d 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
Run database schema review for $ARGUMENTS.
Purpose
Evaluate database schema quality, integrity, and performance risks.
Primary scope
- supabase/migrations/*
- supabase/functions/*
- supabase/tests/*
Workflow
[ ] 1 Inspect schema definition
Read the latest migration files in:
supabase/migrations/*
[ ] 2 Inspect SQL functions and triggers
Review:
supabase/functions/*
[ ] 3 Evaluate schema integrity
Check:
- primary keys
- foreign keys
- unique constraints
- nullability rules
- enum usage
[ ] 4 Evaluate performance risks
Check:
- missing indexes
- large relation scans
- hot tables
- unbounded joins
[ ] 5 Evaluate migration safety
Look for:
- destructive schema changes
- column type rewrites
- large table locks
- incompatible constraints
Load references only when needed
- Review process: Schema review method
- Integrity rules: Database constraints and relationship checks
- Performance rules: Indexing and query optimization guidance
- Security rules: RLS policies and database security checks
Output
Report:
- schema risks
- missing constraints
- index recommendations
- migration safety issues
- suggested improvements
What ships with it
4 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.

database-schema-reviewer is a skill published in the GitHub repository conectlens/lenserfight (18 stars, last pushed 29d ago), licensed MIT. It adds 32 tokens to every session and 331 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 2026-08-30.
