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 | $0.00000 | $0.00632 |
| Opus 5 | $0.00000 | $0.00316 |
| Sonnet 5 | $0.00000 | $0.00126 |
| Haiku 4.5 | $0.00000 | $0.00063 |
Grade A, and why
planetscale 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 7d 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.
How it starts
The opening of the file, as written. The whole thing — 61 lines — stays where its author put it; the contents beside it link to each section on GitHub.
PlanetScale API Skill
Quick Start
PlanetScale provides branching workflows for MySQL. Install the @planetscale/database serverless driver to interact with it seamlessly over HTTP in Edge environments.
npm install @planetscale/database
Common Workflows
Non-Blocking Schema Changes
PlanetScale prohibits direct schema modifications in production. You must branch your database, apply the DDL (e.g., via Prisma db push), test your application, and then create a Deploy Request in PlanetScale to merge the schema change without locking tables.
Production Patterns
Edge Database Access
Traditional MySQL TCP connections (mysql2) are difficult in Vercel Edge/Cloudflare Workers due to connection pooling limits. Always utilize the @planetscale/database fetch-based driver to eliminate connection overhead and utilize connectionless HTTP execution.
Error Recovery
Handle standard MySQL errors wrapped by the serverless driver. The driver natively supports fetch retries. However, schema mismatch errors (e.g., querying a column that hasn't merged to main yet) require application-level feature flagging during the deploy window.
Security Notes
PlanetScale passwords represent highly privileged access. Scope your database passwords explicitly (e.g., read-only for analytics branches).
Performance Considerations
PlanetScale caches connections at the proxy layer, meaning HTTP fetch calls are remarkably fast. However, extremely large payloads over HTTP will incur JSON parsing overhead compared to binary TCP streams. Keep query results paginated.
Testing Guidance
Integrate the PlanetScale CLI (pscale) into your CI/CD. Create a new branch dynamically for every pull request, run your E2E test suite against the branch, and delete it upon success.
Troubleshooting
If you receive 'Foreign key constraints are not supported', note that PlanetScale relies on application-level relations (e.g., via Prisma's relationMode = "prisma") rather than database-level FKs to ensure horizontal scalability across Vitess shards.
What ships with it
7 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.

planetscale is a skill published in the GitHub repository ashish7802/awesome-api-skills (13 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 632 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.
