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 | $0.05930 | $0.05930 |
| Opus 5 | $0.02965 | $0.02965 |
| Sonnet 5 | $0.01186 | $0.01186 |
| Haiku 4.5 | $0.00593 | $0.00593 |
Grade C, and why
sdkck CLAUDE.md scanned grade C with 2 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 6d 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.

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Project Overview
sdkck is an agentic CLI built on the oclif framework that provides tools via a plugin architecture. It uses ESM modules, TypeScript with strict mode, and targets ES2022.
Common Commands
- Build:
npm run build(cleansdist/and compiles TypeScript) - Test:
npm run test(runs mocha, then lint viaposttest) - Run single test:
npx mocha --forbid-only "test/path/to/file.test.ts" - Lint:
npm run lint(ESLint with oclif + prettier configs) - Format:
npm run format(ESLint --fix + Prettier write) - Dev run:
./bin/dev.js <command>(runs CLI from source via ts-node, no build needed) - Production run:
./bin/run.js <command>(runs from compileddist/) - Generate manifest:
npx oclif manifest(createsoclif.manifest.jsonfor packaging)
Architecture
- Framework: oclif v4 — commands are auto-discovered from
src/commands/(compiled todist/commands/). Each file exports a class extendingCommand. - Entry points:
bin/run.js(production),bin/dev.js(development with ts-node/esm loader) - Plugin system: Uses oclif's built-in plugin architecture (
@oclif/plugin-plugins,@oclif/plugin-update, etc.). Third-party plugins are loaded via@oclif/plugin-*glob in package.jsonoclif.plugins. - Topic separator: Space-based (
topicSeparator: " "), so commands usesdkck topic commandnotsdkck topic:command. - Module system: ESM (
"type": "module"in package.json,"module": "Node16"in tsconfig) - Claude Code plugins:
plugins/contains Claude Code plugin definitions (api,cli,mcp) — agents, skills, and hooks that extend Claude Code using sdkck itself. Not part of the TypeScript build.
Built-in Features
API Import (api topic)
api import <source> reads an OpenAPI spec (JSON/YAML), Postman collection, or GraphQL schema (SDL file, introspection JSON, or live endpoint) and stores each operation as a StoredOperation. The name defaults to the spec title slug but can be overridden with --name. The init hook (src/hooks/init/register-api-commands.ts) runs at startup and calls registerApiCommands to load every stored operation as a first-class oclif command under <specName> <operationId>. These dynamic commands appear in sdkck help and sdkck commands exactly like static commands.
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.

sdkck CLAUDE.md is an instructions file published in the GitHub repository hesedcasa/sdkck (9 stars, last pushed 3d ago), licensed Apache-2.0. It adds 5,930 tokens to every session, about $0.0297 per session on Opus 5. A static security scan graded it C with 2 findings (hidden instructions, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
