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 | $0.00018 | $0.00348 |
| Opus 5 | $0.00009 | $0.00174 |
| Sonnet 5 | $0.00004 | $0.00070 |
| Haiku 4.5 | $0.00002 | $0.00035 |
Grade A, and why
database-migrate scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Database Migrate
Generate and apply database migration scripts from schema changes.
When to Use This Skill
Use when the user modifies database models and needs to create a migration, or when applying pending migrations to an environment.
Implementation Steps
Step 1: Detect Migration Tool
Check the project for migration tooling:
alembic.ini→ Alembic (Python / SQLAlchemy)knexfile.js→ Knex (Node.js)dbconfig.yml→ Goose (Go)
Step 2: Generate Migration
Create a new migration file from the current model diff:
- Alembic:
alembic revision --autogenerate -m "$DESCRIPTION" - Knex:
npx knex migrate:make $DESCRIPTION - Goose:
goose create $DESCRIPTION sql
Step 3: Review the Migration
Display the generated SQL and ask the user to confirm:
- Check for destructive operations (DROP TABLE, DROP COLUMN)
- Verify index additions won't lock large tables
- Confirm data backfill steps are idempotent
Step 4: Apply
Run the migration against the target database:
- Alembic:
alembic upgrade head - Knex:
npx knex migrate:latest - Goose:
goose up
Report the migration version and any errors.
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-migrate is a skill published in the GitHub repository stbenjam/skillsaw (59 stars, last pushed 4d ago), licensed Apache-2.0. It adds 18 tokens to every session and 348 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 2026-08-30.
