What it does

Makemigrations is an agent skill from deusXmachina-dev/memorylane. Create SQLite migrations for MemoryLane storage schema changes. Use when interfaces or persisted fields change in src/main/storage/index.ts, when a new column/index/table/trigger is needed, or when the user asks to add a migration similar to 0001initialschema.ts.

Its SKILL.md is about 970 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Databases. It works with SQLite. The licence is GPL-3.0.

When your agent uses it

Persisted fields change in src/main/storage/index.ts
A new column/index/table/trigger is needed
The user asks to add a migration similar to 0001initialschema.ts

Example prompts

“/makemigrations”

Workflow steps

6 steps, taken from the step headings in SKILL.md.

Identify schema delta
Create migration file
Implement safe SQL
Register migration
Tests
Validate

What it can do on your machine

Read from SKILL.md and the folder at commit 16abbe0. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- npm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Makemigrations loads about 973 tokens when it runs. Until then it costs about 70 tokens; SKILL.md has 340 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~70
When it runs · the whole SKILL.md, loaded when a task matches: ~973

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

name: makemigrations
description: Create SQLite migrations for MemoryLane storage schema changes. Use when interfaces or persisted fields change in src/main/storage/index.ts, when a new column/index/table/trigger is needed, or when the user asks to add a migration similar to 0001_initial_schema.ts.

Create Storage Migration

Purpose

Keep runtime storage schema in sync with src/main/storage/index.ts by adding forward-only migrations in src/main/storage/migrations/.

When to Use

Use this skill when any persisted shape changes, especially:

StoredActivity or ActivitySummary field changes in src/main/storage/index.ts
SQL statements in StorageService change selected/inserted columns
New filters require indexes
Legacy table/data needs migration into current tables

Rules

Never edit or reorder existing migration files after they ship.
Always add a new migration with a monotonically increasing 4-digit prefix (0003_*, 0004_*, ...).
Migration must be idempotent where possible (IF EXISTS / IF NOT EXISTS).
Migration must be safe on partially migrated user data.
Register the new migration in src/main/storage/migrations/index.ts.

Workflow

Copy this checklist and execute in order:

text

Migration Progress
- [ ] 1) Identify schema delta from index.ts changes
- [ ] 2) Create next migration file in src/main/storage/migrations/
- [ ] 3) Implement migration.up(db) with safe SQL
- [ ] 4) Register migration in src/main/storage/migrations/index.ts
- [ ] 5) Add/update storage migration tests
- [ ] 6) Run tests and lint for touched files

1) Identify schema delta

Map TypeScript/API changes to SQLite changes:

Added persisted field -> ALTER TABLE ... ADD COLUMN (or backfill strategy)
Removed field -> usually keep column; stop reading/writing it first, remove later with explicit migration plan
Renamed field -> add new column + backfill + dual-read/write strategy if needed
New query pattern -> add index
New text search shape -> update FTS table/trigger strategy
Vector shape/dimension changes -> explicit data migration strategy

2) Create migration file

Name pattern:

File: src/main/storage/migrations/000X_descriptive_name.ts
Export: export const migration: Migration
name must match file stem exactly (example: 0003_add_window_title_index)

Template:

typescript

import Database from 'better-sqlite3'
import type { Migration } from '../migrator'

export const migration: Migration = {
  name: '000X_descriptive_name',
  up(db: Database.Database): void {
    // schema/data updates
  },
}

3) Implement safe SQL

Preferred patterns:

db.exec(...) for DDL batches
db.prepare(...).run() for parameterized DML
Guard checks using sqlite_master when needed
Wrap multi-step data migrations in db.transaction(() => { ... })()

For data moves:

Use INSERT OR IGNORE where duplicate IDs may exist
Backfill defaults for new NOT NULL columns
Drop legacy objects only after successful copy

4) Register migration

Update src/main/storage/migrations/index.ts:

Add import for the new migration
Append to migrations array at the end (preserve order)

5) Tests

Update src/main/storage/storage.test.ts (or related tests) to cover:

Fresh DB applies all migrations successfully
Existing DB at previous schema upgrades correctly
Backfilled/default values are correct
Expected indexes/tables/triggers exist after migration

6) Validate

Run relevant checks:

bash

npm test -- src/main/storage/storage.test.ts
npm run lint

If tests are broad or expensive, run targeted tests first, then full suite when requested.

Examples in Repo

Baseline schema setup: src/main/storage/migrations/0001_initial_schema.ts
Legacy data migration + cleanup: src/main/storage/migrations/0002_migrate_context_events.ts
