claworc: Agent for Claude Code

.claude/agents/migration-author.md

migration-author is an agent for Claude Code from gluk-w/claworc. It costs 100 tokens per session (2,117 once invoked), scanned C, original, no licence file.

A coding agent that creates Go database migration files for schema changes that cannot be handled by automatic updates, or for filling existing data.

In plain words
What is it for?
Use it for data backfills or seeds, column type changes, dropped or renamed columns, and database constraints that automatic migration cannot express.
Why use it?
It helps avoid changing a database structure manually when a change could remove, rename, or alter data and needs a recorded migration.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter.

This is gluk-w/claworc's own configuration. It tells Claude Code how to work on claworc itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything claworc configures →

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 C, and why

migration-author scanned grade C with 1 finding 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 2mo 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.

Tells the agent never to refusehighAnti-refusal

Suppressing the ability to decline removes a core safety control; a later harmful request then succeeds.

- **Destructive change (drop a column with data, narrow a type).** Author the migration, but add a one-line comment above the body noting the data loss. Don't refuse.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.
