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 | $0.00033 | $0.00355 |
| Opus 5 | $0.00016 | $0.00178 |
| Sonnet 5 | $0.00007 | $0.00071 |
| Haiku 4.5 | $0.00003 | $0.00036 |
Grade A, and why
generate-migration 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
Act as Database Worker. Create a migration for: {migration_description}
- Run context-builder:
python3 .cursor/context/context-builder.py \ --phase database --task "{migration_description}" --agent database-worker \ --keywords "migration,schema,index" - Read
.memory/constraints.mdandAGENTS.md §3(migrations path)
Migration Location
Determined by AGENTS.md §3 — e.g.:
- TypeORM:
<backend_path>/database/migrations/YYYYMMDDHHMMSS-{Name}.ts - Prisma:
prisma/migrations/YYYYMMDDHHMMSS_{name}/migration.sql - Alembic:
alembic/versions/YYYYMMDDHHMMSS_{name}.py
Rules
- Both
up()anddown()— never a one-way migration - UUID or ULID primary keys (avoid auto-increment for distributed safety)
- Timestamp columns:
created_at,updated_at(timezone-aware) deleted_atfor soft delete where applicable- Indexes on all foreign keys and high-cardinality filter columns
CHECKconstraints on logical business rules- Never enable ORM auto-sync (
synchronize: falseor equivalent) - Apply compliance columns from
AGENTS.md §5(e.g.tenant_idfor multi-tenancy, encrypted fields for PII)

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.

generate-migration is a command published in the GitHub repository phuoctrung-ppt/ai-sdlc-workflow (2 stars, last pushed 19d ago), licensed MIT. It adds 33 tokens to every session and 355 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 2026-08-31.
