Token cost

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.

Security

Grade A, and why

migration-preview 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 8d 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-preview

Routing skill for database migration work. Loads the memory-bank files relevant for schema changes and data backfills.

Load:

  • memory-bank/project/brief.md
  • memory-bank/technical/architecture.md
  • memory-bank/project/domain.md
  • memory-bank/technical/stack.md (for migration tooling and conventions)

Reminder: schema changes touch durable state. Confirm the migration is reversible (or that irreversibility is intentional and documented) before applying. See docs/automation-patterns.md if a bot will write the migration log entry.

No knowledge in this file — the listed files are the source. memory-bank/_index.md is the inventory if you need to discover what else exists.

Changes

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.
