Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00077 | $0.02344 |
| Opus 5 | $0.00039 | $0.01172 |
| Sonnet 5 | $0.00015 | $0.00469 |
| Haiku 4.5 | $0.00008 | $0.00234 |
Grade A, and why
kafka-schema-registry 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 8d 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.

Kafka Schema Registry Skill
Scan a project to identify Kafka applications, extract schemas, generate Terraform for Schema Registry registration, and produce a comprehensive analysis report.
When to Use
Invoke this skill when:
- A user asks to analyze a project for Kafka usage in order to add event schemas or integrate Schema Registry
- A user wants to extract schemas from Kafka producers
- A user wants Terraform to register schemas to Schema Registry
- A user wants to audit Kafka producer/consumer configurations
Deliverables
This skill produces 3 outputs in the target project:
schema-report.md— Full analysis report with findings, risks, and upgrade recommendationsschemas/— Extracted schema files (Avro, JSON Schema, Protobuf) with PII taggingterraform/— Terraform configs using Confluent provider to register schemas
Optional: Code Migration Assistance
If the user asks for their application code to be updated to integrate Schema Registry, use the Code Migration Reference to update the code with proper Schema Registry integration patterns.
High-Level Workflow
Phase 0: Initialize
- Check for existing
schema.yamlandschemas/directory manually - Note any existing schema infrastructure in the report
Phase 1: Project Scan & Kafka Detection
- Find build files — Search for
pom.xml,build.gradle,requirements.txt,package.json, etc. - Detect Kafka dependencies — Look for
spring-kafka,confluent-kafka,kafkajs, etc. - Find producers & consumers — Grep for
KafkaTemplate,Producer(,producer.send, etc. - Extract topic names — From string literals, config properties, YAML files
- Identify serializers — Find
value.serializer,KafkaAvroSerializer, custom serializers - Build app catalog — Compile findings: app name, language, role, topics, serializer, category

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.
