bump-schema

bump-schema is a command for Claude Code from korjwl1/toki. It costs 0 tokens per session (194 once invoked), scanned A, original, MIT.

A command that increments the database schema version after a change makes stored event data incompatible with the code.

In plain words
What is it for?
Use it after changing stored event fields, database key layouts, dictionary encoding, checkpoint format, or other serialized data structures.
Why use it?
It tells the application that rebuildable event databases need to be reset and rebuilt. It helps prevent new code from misreading old serialized data.

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

bump-schema 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

Bump the DB schema version after a structural change.

When to use

Run this command after modifying any of the following:

  • StoredEvent struct fields (src/common/types.rs)
  • Existing event-DB key/value encoding or keyspace layout in Database::open (src/db.rs)
  • Dictionary encoding format (src/db.rs)
  • Checkpoint format (src/checkpoint.rs)
  • Any change that makes existing serialized data incompatible with new code

Instructions

  1. Read src/db.rs and find the current SCHEMA_VERSION constant
  2. Increment it by 1
  3. Commit with message: chore: bump schema version to {NEW_VERSION}

This resets only the rebuildable <provider>.fjall event databases on next daemon start. It must not reset <provider>.windows.fjall: window history has its own WINDOWS_SCHEMA_VERSION and may not be reconstructable.

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.
