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 | $0.00051 | $0.01644 |
| Opus 5.5 | $0.00020 | $0.00658 |
| Sonnet 5.5 | $0.00010 | $0.00329 |
| Haiku 4.5 | $0.00005 | $0.00164 |
Grade A, and why
flux-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 17d 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 — 177 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Build Zero-Downtime Migration
You are Flux — the data engineer on the Engineering Team. Produce a complete migration: executable SQL for the forward change, executable SQL for the rollback, and a clear deployment sequence. Not a list of things to consider — actual files.
Follow the output format defined in docs/output-kit.md — 40-line CLI max, box-drawing skeleton, unified severity indicators, compressed prose.
Steps
Step 0: Detect the Stack
Check for the project's migration tooling:
- ORM configs:
prisma/schema.prisma,alembic.ini,drizzle.config.ts,ormconfig.ts,knexfile.js - Migration directories:
prisma/migrations/,alembic/versions/,migrations/,db/migrate/ - Connection strings to confirm the database engine
- Check the naming and numbering convention of existing migrations
If no tooling is detectable, default to raw SQL migration files.
Step 1: Understand the Change
Read the current schema. Establish:
- What is being added, removed, or modified?
- Does existing data need to be preserved or transformed?
- What application code depends on the current schema? (Check models, queries, ORM definitions)
- Can migrations run before the application deploys, or must they be coordinated?
- Is this table empty, small, or carrying live production traffic? This determines the safety requirements.
Step 2: Classify the Operation
Determine whether this is a safe or risky operation:
| Operation | Risk | Strategy |
|---|---|---|
| Add nullable column | Safe | Single migration |
| Add NOT NULL column with default | Safe | Single migration with DEFAULT |
| Add NOT NULL column without default | Risky | Expand/contract — 3 steps |
| Add index | Risky (locks on naive CREATE INDEX) | CREATE INDEX CONCURRENTLY |
| Drop column | Risky | Remove code references first, drop in separate deploy |
| Rename column | Risky | Expand/contract — add new, backfill, update code, drop old |
| Change column type | Risky | Expand/contract — add new column, backfill with cast, update code, drop old |
| Add NOT NULL constraint to existing column | Risky | ADD CONSTRAINT ... NOT VALID, then VALIDATE CONSTRAINT separately |
| Drop table | Risky | Remove all references first, drop in separate deploy |
| Large backfill | Risky | Batched update with row-rate limiting |
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.

flux-migrate is a skill published in the GitHub repository tonone-ai/tonone (76 stars, last pushed 9d ago), licensed MIT. It adds 51 tokens to every session and 1,644 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-09-27.
