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.

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 | $0.00000 | $0.03480 |
| Opus 5.5 | $0.00000 | $0.01392 |
| Sonnet 5.5 | $0.00000 | $0.00696 |
| Haiku 4.5 | $0.00000 | $0.00348 |
Grade A, and why
case-dev 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 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.
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.
How it starts
The opening of the file, as written. The whole thing — 617 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Case.dev SDK Skill
Purpose
This skill covers the Case.dev API platform integration for legal tech applications, including document vaults, AI models, OCR, transcription, and workflows.
Key Concepts
- Vaults: Encrypted document storage with semantic search and RAG
- LLMs: Unified gateway to 130+ AI models (Claude, GPT-4, CaseMark Core 1)
- OCR: Production-grade document digitization with table extraction
- Voice: Transcription with speaker diarization for depositions
- Workflows: 700+ expert-crafted legal prompts and processing pipelines
- Orbit Compute: Serverless functions and app deployments
Setup
Installation
# TypeScript/JavaScript
bun add git+ssh://[email protected]:stainless-sdks/router-typescript.git
# Once published to npm:
# bun add casedev
Environment Variables
# .env.local
CASE_API_KEY=sk_case_...
CASEDEV_API_KEY=sk_case_...
Initialize Client
// lib/case-dev/client.ts
import Casedev from 'casedev';
export const casedev = new Casedev({
apiKey: process.env.CASEDEV_API_KEY!,
environment: 'production', // or 'local' for development
});

Vaults - Document Storage
Create a Vault
// lib/case-dev/vaults.ts
import { casedev } from './client';
export async function createVault(name: string, description?: string) {
const vault = await casedev.vault.create({
name,
description,
});
return vault;
}
Upload Document to Vault
export async function uploadDocument(
vaultId: string,
file: File,
options?: {
ocr?: boolean;
semanticIndex?: boolean;
}
) {
const formData = new FormData();
formData.append('file', file);
formData.append('vault_id', vaultId);
if (options?.ocr) {
formData.append('ocr', 'true');
}
if (options?.semanticIndex) {
formData.append('semantic_index', 'true');
}
const doc = await casedev.vault.upload(formData);
return doc;
}
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.

case-dev is a skill published in the GitHub repository CaseMark/casedotdev-starter-app (2 stars, last pushed 1mo ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 3,480 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
