What it does

Migration Codegen is an agent skill from AHS12/thoth-blueprint. Change Laravel, TypeORM, or Django migration generation and generated SQL parsing. Use when modifying framework code generation, foreign keys, indexes, naming, or migration artifacts.

Its SKILL.md is about 430 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 Backend & APIs, covering Backend development, Project scaffolding and SQL. It works with SQL, Django, Laravel and TypeORM. The repository describes itself as: Design databases the way you think. Create unlimited schemas, import existing designs, visualize relationships, export to multiple formats, and generate framework migrations… The licence is GPL-3.0.

What it can do on your machine

Read from SKILL.md and the folder at commit 075e0e3. 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
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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

Migration Codegen loads about 425 tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 188 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~50
When it runs · the whole SKILL.md, loaded when a task matches: ~425

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.

description: Change Laravel, TypeORM, or Django migration generation and generated SQL parsing. Use when modifying framework code generation, foreign keys, indexes, naming, or migration artifacts.

Migration Code Generation

Read First

src/lib/codegen/ and its Laravel, TypeORM, and Django generators.
src/lib/exporter/ for dialect-specific SQL generation.
src/lib/types.ts for columns, indexes, and edge metadata.
src/lib/utils.ts for IDs and relationship helpers.

Change Rules

Keep framework conventions explicit: Laravel timestamps and inferred foreign-key names, TypeORM's SQL parsing assumptions, and Django's yourapp placeholder.
Validate identifier quoting, nullable/default/generated columns, indexes, composite foreign keys, on-delete/on-update behavior, and table ordering.
Do not assume generated SQL has one formatting shape. If a generator parses SQL, keep the parser tolerant of the SQL it emits and test alterations as well as creates.
Preserve hyphenated IDs when resolving handles and columns. Never use split("-")[0] as a column-ID parser.
Treat output as a candidate artifact. Do not claim a migration is executable without reviewing or executing it against the target framework/database.

Verification

Generate artifacts for empty, single-table, indexed, related, composite-key, and altered schemas.
Inspect generated files for valid syntax, deterministic naming, and correct foreign-key direction.
Exercise each supported database type where the generator accepts it.
Run type-check, lint, and build; manually review generated output because no generated SQL test runner is configured.
