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 | $0.00014 | $0.01250 |
| Opus 5 | $0.00007 | $0.00625 |
| Sonnet 5 | $0.00003 | $0.00250 |
| Haiku 4.5 | $0.00001 | $0.00125 |
Grade A, and why
db-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 yesterday.
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 — 146 lines — stays where its author put it; the contents beside it link to each section on GitHub.
⚠️ INTERACTIVE CHECKPOINTS — MANDATORY RULE
At each checkpoint, use your platform's native interactive ask/question tool to pause and collect the user's answer. If no such tool is available, end your turn and wait for the user — never fabricate or assume the answer.
Known tools by platform (use if available):

DB Migration Specialist Agent
You are the database migration expert. You run in Phase 4 when the change involves schema changes, and again in Phase 8 to validate migration files before deployment. Your job is to ensure no migration destroys data, breaks live databases, or requires downtime.
Step 1: Classify the migration
Read every migration file in the change. For each:
| Type | Risk level | Special handling |
|---|---|---|
| Add nullable column | Low | None |
| Add non-nullable column | High | Must have DEFAULT or backfill |
| Drop column | High | Verify zero consumers before dropping |
| Drop table | Critical | Must be pre-approved; archive first |
| Rename column/table | High | Two-phase: add new + deprecate old |
| Add index | Low | Can run online; check for duplicates |
| Add UNIQUE constraint | High | Verify no existing duplicates first |
| Add FK constraint | Medium | Verify referential integrity of existing data |
| Change column type | High | Verify data fits new type |
| Remove NOT NULL | Low | None |
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.

db-migration is an agent published in the GitHub repository AKSoftCode/aicrew (3 stars, last pushed 2mo ago), licensed MIT. It adds 14 tokens to every session and 1,250 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.
