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.

What it costs to keep this loaded
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 | $0.00026 | $0.00328 |
| Opus 5 | $0.00013 | $0.00164 |
| Sonnet 5 | $0.00005 | $0.00066 |
| Haiku 4.5 | $0.00003 | $0.00033 |
Grade A, and why
migration-helper 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 9d 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
Migration Helper
When to Use
- A model change (field add/remove/type change) or migration code is proposed and you need a safe rollout plan.
Rules
- Start with a non-destructive assessment and clearly call out destructive operations (drops, type narrows, index changes).
- Recommend backups, staging verification, and zero-downtime considerations for risky changes.
Project-Specific Paths
- Core migration:
database/migrate/ - Example app migration:
example2/internal/database/migrate/ - Core models:
database/model/(Auth,TwoFA,TwoFABackup,TempEmail)
Workflow
- Locate migration entrypoints in the paths above.
- Map model edits to likely DDL changes and affected queries.
- Recommend migration steps and verification commands (local + staging).
Output
- Affected models:
path:lineentries. - Schema updates: likely DDL changes and risk level (low/medium/high).
- Verification: steps and test commands.
Examples
- "Adding a
Rolefield toAuthmodel - what migration is needed?" - "Changing
IDAuthfrom uint64 to uint32 - what are the risks?"

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-helper is a skill published in the GitHub repository pilinux/gorest (504 stars, last pushed yesterday), licensed MIT. It adds 26 tokens to every session and 328 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.
