repoforge: Skill for Claude Code

.claude/skills/backend/generation/SKILL.md

add-generation-event is a skill for Claude Code from JNZader/repoforge. It costs 30 tokens per session (493 once invoked), scanned A, original, MIT.

A guide to creating and recording Generation and GenerationEvent database records. An ORM is a programming layer that lets code work with database records as objects.

In plain words
What is it for?
Use it when creating a generation record or logging an event linked to a particular generation.
Why use it?
It gives backend code a consistent way to store generations and the events associated with them.

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

add-generation-event 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 1mo 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

add-generation-event

This skill covers the creation and management of Generation and GenerationEvent ORM models.

Trigger: When working with generation data in the backend.

Quick Reference

Task Pattern
Create a Generation create-generation
Log a GenerationEvent log-generation-event

Critical Patterns (Summary)

  • Create a Generation: Use the Generation model to create new generation records.
  • Log a GenerationEvent: Utilize the GenerationEvent model to log events related to generations.

Critical Patterns (Detailed)

Create a Generation

This pattern demonstrates how to create a new Generation record using the Generation model.

from apps.server.app.models.generation import Generation
from uuid import uuid4
from datetime import datetime

new_generation = Generation(
    id=uuid4(),
    created_at=datetime.utcnow(),
    updated_at=datetime.utcnow()
)

Log a GenerationEvent

This pattern shows how to log a GenerationEvent related to a specific Generation.

from apps.server.app.models.generation import GenerationEvent
from uuid import uuid4
from datetime import datetime

event = GenerationEvent(
    id=uuid4(),
    generation_id=new_generation.id,
    event_time=datetime.utcnow(),
    description="Generation created"
)

When to Use

  • When you need to create a new generation record in the database.
  • When logging events related to a specific generation for tracking purposes.

Commands

python -m apps.server.app.models.generation

Anti-Patterns

Don't: Create Generation without Validation

Creating a Generation without proper validation can lead to data integrity issues.

# BAD
new_generation = Generation(id=None)  # Missing required fields

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.
