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 | $0.00015 | $0.00269 |
| Opus 5 | $0.00008 | $0.00134 |
| Sonnet 5 | $0.00003 | $0.00054 |
| Haiku 4.5 | $0.00002 | $0.00027 |
Grade A, and why
migration-run 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 6d 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 Migrations
- Check current migration status:
npx prisma migrate status 2>/dev/null \
|| npx knex migrate:status 2>/dev/null \
|| npx sequelize-cli db:migrate:status 2>/dev/null \
|| ls migrations/ | tail -5
-
Show pending migrations and what each one does (read migration files).
-
Ask for confirmation before running.
-
Run migrations:
npx prisma migrate deploy 2>/dev/null \
|| npx knex migrate:latest 2>/dev/null \
|| npx sequelize-cli db:migrate 2>/dev/null
-
Verify the result - check migration status again to confirm all are applied.
-
If migration fails:
- Show the exact error
- Check if it's a data conflict, constraint violation, or connection issue
- Suggest rollback if needed:
npx prisma migrate reset(caution: destructive) - Provide targeted fix
Safety rule: Never suggest dropping data without explicit confirmation and backup verification.
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.

migration-run is a skill published in the GitHub repository berkcangumusisik/claude-code-practices (10 stars, last pushed 4mo ago), licensed MIT. It adds 15 tokens to every session and 269 once invoked, about $0.0001 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 2026-08-31.
